Supporting the delivery of cost-effective interventions in primary health-care systems in low-income and middle-income countries: an overview of systematic reviews

Uneven primary healthcare supply of rural doctors and medical equipment in remote China: community impact and the moderating effect of policy intervention

BACKGROUND

Unequal access to primary healthcare (PHC) has become a critical issue in global health inequalities, requiring governments to implement policies tailored to communities' needs and abilities. However, the place-based facility dimension of PHCs is oversimplified in current healthcare literature, and formulating the equity-oriented PHC spatial planning remains challenging without understanding the multiple impacts of community socio-spatial dynamics, particularly in remote areas. This study aims to push the boundary of PHC studies one step further by presenting a nuanced and dynamic understanding of the impact of community environments on the uneven primary healthcare supply.

METHODS

Focusing on Shuicheng, a remote rural area in southwestern China, multiple data are included in this village-based study, i.e., the facility-level healthcare statistics data (2016-2019), the statistical yearbooks, WorldPop, and Chinese GDP's spatial distribution data. We evaluate villages' PHC service capacity using the number of doctors and essential equipment per capita, which are the major components of China's PHC delivery. The indicators describing community environments are selected based on extant literature and China's planning paradigms, including town- and village-level factors. Gini coefficients and local spatial autocorrelation analysis are used to present the divergences of PHC capacity, and multilevel regression model and (heterogeneous) difference in difference model are used to examine the driving role of community environments and the dynamics under the policy intervention.

RESULTS

Despite the general improvement, PHC inequalities remain significant in remote rural areas. The village's location, aging, topography, ethnic autonomy, and economic conditions significantly influence village-level PHC capacity, while demographic characteristics and healthcare delivery at the town level are also important. Although it may improve the hardware setting in village clinics (coef. = 0.350), the recent equity-oriented policy attempts may accelerate the loss of rural doctors (coef. = - 0.517). Notably, the associations between PHC and community environments are affected inconsistently by this round of policy intervention. The town healthcare centers with higher inpatient service capacity (coef. = - 0.514) and more licensed doctors (coef. = - 0.587) and nurses (coef. = - 0.344) may indicate more detrimental policy effects that reduced the number of rural doctors, while the centers with more professional equipment (coef. = 0.504) and nurses (coef. = 0.184) are beneficial for the improvement of hardware setting in clinics.

CONCLUSIONS

The findings suggest that the PHC inequalities are increasingly a result of joint social, economic, and institutional forces in recent years, underlining the increased complexity of the PHC resource allocation mechanism. Therefore, we claim the necessity to incorporate a broader understanding of community orientation in PHC delivery, particularly the interdisciplinary knowledge of the spatial lens of community, to support its sustainable development. Our findings also provide timely policy insights for ongoing primary healthcare reform in China.

Reforms and innovations in primary health care in different countries: scoping review

INTRODUCTION

The World Health Organization (WHO) recommends focusing on primary health care (PHC) as the first strategy of countries to achieve the improvement of the health level of communities and has emphasized it again in 2021. Therefore, we intend to take a different look at the PHC system with reform, innovation, and initiative by using the experiences of leading countries and identify practical and evidence-based solutions to achieve greater health.

METHODS

This is a scoping review study that has identified innovations and reforms related to PHC since the beginning of 2000 to the end of 2022. In this study, Scopus, Web Of Science, and PubMed databases have been searched using appropriate keywords. This study is done in six steps using Arkesy and O'Malley framework. In this study, the framework of six building blocks of WHO was used to summarize and report the findings.

RESULTS

By searching in different databases, we identified 39426 studies related to reforms in primary care, and after the screening process, 106 studies were analyzed. Our findings were classified and reported into 9 categories (aims, stewardship/leadership, financing & payment, service delivery, health workforce, information, outcomes, policies/considerations, and limitations).

CONCLUSION

The necessity and importance of strengthening PHC is obvious to everyone due to its great consequences, which requires a lot of will, effort, and coordination at the macro-level of the country, various organizations, and health teams, as well as the participation of people and society.

Interventions for improving coverage of childhood immunisation in low- and middle-income countries

BACKGROUND

Immunisation plays a major role in reducing childhood morbidity and mortality. Getting children immunised against potentially fatal and debilitating vaccine-preventable diseases remains a challenge despite the availability of efficacious vaccines, particularly in low- and middle-income countries. With the introduction of new vaccines, this becomes increasingly difficult. There is therefore a current need to synthesise the available evidence on the strategies used to bridge this gap. This is a second update of the Cochrane Review first published in 2011 and updated in 2016, and it focuses on interventions for improving childhood immunisation coverage in low- and middle-income countries.

OBJECTIVES

To evaluate the effectiveness of intervention strategies to boost demand and supply of childhood vaccines, and sustain high childhood immunisation coverage in low- and middle-income countries.

SEARCH METHODS

We searched CENTRAL, MEDLINE, CINAHL, and Global Index Medicus (11 July 2022). We searched Embase, LILACS, and Sociological Abstracts (2 September 2014). We searched WHO ICTRP and ClinicalTrials.gov (11 July 2022). In addition, we screened reference lists of relevant systematic reviews for potentially eligible studies, and carried out a citation search for 14 of the included studies (19 February 2020).

SELECTION CRITERIA

Eligible studies were randomised controlled trials (RCTs), non-randomised RCTs (nRCTs), controlled before-after studies, and interrupted time series conducted in low- and middle-income countries involving children that were under five years of age, caregivers, and healthcare providers.

DATA COLLECTION AND ANALYSIS

We independently screened the search output, reviewed full texts of potentially eligible articles, assessed the risk of bias, and extracted data in duplicate, resolving discrepancies by consensus. We conducted random-effects meta-analyses and used GRADE to assess the certainty of the evidence.

MAIN RESULTS

Forty-one studies involving 100,747 participants are included in the review. Twenty studies were cluster-randomised and 15 studies were individually randomised controlled trials. Six studies were quasi-randomised. The studies were conducted in four upper-middle-income countries (China, Georgia, Mexico, Guatemala), 11 lower-middle-income countries (Côte d'Ivoire, Ghana, Honduras, India, Indonesia, Kenya, Nigeria, Nepal, Nicaragua, Pakistan, Zimbabwe), and three lower-income countries (Afghanistan, Mali, Rwanda). The interventions evaluated in the studies were health education (seven studies), patient reminders (13 studies), digital register (two studies), household incentives (three studies), regular immunisation outreach sessions (two studies), home visits (one study), supportive supervision (two studies), integration of immunisation services with intermittent preventive treatment of malaria (one study), payment for performance (two studies), engagement of community leaders (one study), training on interpersonal communication skills (one study), and logistic support to health facilities (one study). We judged nine of the included studies to have low risk of bias; the risk of bias in eight studies was unclear and 24 studies had high risk of bias. We found low-certainty evidence that health education (risk ratio (RR) 1.36, 95% confidence interval (CI) 1.15 to 1.62; 6 studies, 4375 participants) and home-based records (RR 1.36, 95% CI 1.06 to 1.75; 3 studies, 4019 participants) may improve coverage with DTP3/Penta 3 vaccine. Phone calls/short messages may have little or no effect on DTP3/Penta 3 vaccine uptake (RR 1.12, 95% CI 1.00 to 1.25; 6 studies, 3869 participants; low-certainty evidence); wearable reminders probably have little or no effect on DTP3/Penta 3 uptake (RR 1.02, 95% CI 0.97 to 1.07; 2 studies, 1567 participants; moderate-certainty evidence). Use of community leaders in combination with provider intervention probably increases the uptake of DTP3/Penta 3 vaccine (RR 1.37, 95% CI 1.11 to 1.69; 1 study, 2020 participants; moderate-certainty evidence). We are uncertain about the effect of immunisation outreach on DTP3/Penta 3 vaccine uptake in children under two years of age (RR 1.32, 95% CI 1.11 to 1.56; 1 study, 541 participants; very low-certainty evidence). We are also uncertain about the following interventions improving full vaccination of children under two years of age: training of health providers on interpersonal communication skills (RR 5.65, 95% CI 3.62 to 8.83; 1 study, 420 participants; very low-certainty evidence), and home visits (RR 1.29, 95% CI 1.15 to 1.45; 1 study, 419 participants; very low-certainty evidence). The same applies to the effect of training of health providers on interpersonal communication skills on the uptake of DTP3/Penta 3 by one year of age (very low-certainty evidence). The integration of immunisation with other services may, however, improve full vaccination (RR 1.29, 95% CI 1.16 to 1.44; 1 study, 1700 participants; low-certainty evidence).

AUTHORS' CONCLUSIONS

Health education, home-based records, a combination of involvement of community leaders with health provider intervention, and integration of immunisation services may improve vaccine uptake. The certainty of the evidence for the included interventions ranged from moderate to very low. Low certainty of the evidence implies that the true effect of the interventions might be markedly different from the estimated effect. Further, more rigorous RCTs are, therefore, required to generate high-certainty evidence to inform policy and practice.

Determinants of non-institutional childbirth: Evidence from the Peruvian demographic and health survey

Objective

We aimed to evaluate the determinants of non-institutional delivery among women of childbearing age in Peru.

Methods

We conducted a secondary analysis of data from the Peru 2019 Demographic and Family Health Survey (ENDES). This multi-stage survey sampling is representative at the urban-rural, regional, and national levels. The outcome variable was place of delivery, collected by self-reporting. Binary logistic regression models were used to assess the factors associated with non-institutionalized delivery. Thus, we estimated crude and adjusted odd ratios (aOR). For the multivariable model, the manual forward selection method and the Wald test were used to obtain a final parsimonious model.

Results

The final sample included 14,061 women of reproductive age between the ages of 15 and 49. The prevalence of non-institutional delivery was 7.8 %. Multivariate regression analysis found that having a secondary education (aOR:0.48; 95 % confidence interval [CI]:0.39-0.58) or higher (aOR:0.57; 95 %CI:0.42-0.78); belonging to the second (aOR:0.26; 95 %CI:0.20-0.33), third (aOR:0.28; 95 %CI:0.21-0.38), fourth (aOR:0.21; 95 %CI:0.13-0.33), or fifth wealth quintile (aOR:0.15; 95 %CI:0.09-0.27); and suffering intimate partner violence (aOR:0.76; 95 %CI:0.64-0.91) were associated with lower odds of non-institutional delivery, while not having some type of health insurance (aOR:3.12; 95 %CI:2.47-3.95), living in a rural area (aOR:1.93; 95 %CI:1.54-2.42), and having had three or more deliveries (aOR:1.36; 95 %CI:1.07-1.72), were associated with higher odds of non-institutional delivery.

Conclusions

We found that not having health insurance, residing in a rural area, and having had three or more deliveries were factors associated with non-institutional delivery in women of childbearing age. We propose that should focus public health strategies towards providing education to women about maternal health, and likewise, facilitating access to specialized health centers for rural populations.

Implementation strategies for knowledge products in primary healthcare: a systematic review of systematic reviews (Preprint)

Background

The underuse or overuse of knowledge products leads to waste in health care, and primary care is no exception.

Objective

This study aimed to characterize which knowledge products are frequently implemented, the implementation strategies used in primary care, and the implementation outcomes that are measured.

Methods

We performed a systematic review (SR) of SRs using the Cochrane systematic approach to include eligible SRs. The inclusion criteria were any primary care contexts, health care professionals and patients, any Effective Practice and Organization of Care implementation strategies of specified knowledge products, any comparators, and any implementation outcomes based on the Proctor framework. We searched the MEDLINE, EMBASE, CINAHL, Ovid PsycINFO, Web of Science, and Cochrane Library databases from their inception to October 2019 without any restrictions. We searched the references of the included SRs. Pairs of reviewers independently performed selection, data extraction, and methodological quality assessment by using A Measurement Tool to Assess Systematic Reviews 2. Data extraction was informed by the Effective Practice and Organization of Care taxonomy for implementation strategies and the Proctor framework for implementation outcomes. We performed a descriptive analysis and summarized the results by using a narrative synthesis.

Results

Of the 11,101 records identified, 81 (0.73%) SRs were included. Of these 81, a total of 47 (58%) SRs involved health care professionals alone. Moreover, 15 SRs had a high or moderate methodological quality. Most of them addressed 1 type of knowledge product (56/81, 69%), common clinical practice guidelines (26/56, 46%) or management, and behavioral or pharmacological health interventions (24/56, 43%). Mixed strategies were used for implementation (67/81, 83%), predominantly education-based (meetings in 60/81, 74%; materials distribution in 59/81, 73%; and academic detailing in 45/81, 56%), reminder (53/81, 36%), and audit and feedback (40/81, 49%) strategies. Education meetings (P=.13) and academic detailing (P=.11) seemed to be used more when the population was composed of health care professionals alone. Improvements in the adoption of knowledge products were the most commonly measured outcome (72/81, 89%). The evidence level was reported in 12% (10/81) of SRs on 62 outcomes (including 48 improvements in adoption), of which 16 (26%) outcomes were of moderate or high level.

Conclusions

Clinical practice guidelines and management and behavioral or pharmacological health interventions are the most commonly implemented knowledge products and are implemented through the mixed use of educational, reminder, and audit and feedback strategies. There is a need for a strong methodology for the SR of randomized controlled trials to explore their effectiveness and the entire cascade of implementation outcomes.

How effects on health equity are assessed in systematic reviews of interventions

BACKGROUND

Enhancing health equity is endorsed in the Sustainable Development Goals. The failure of systematic reviews to consider potential differences in effects across equity factors is cited by decision-makers as a limitation to their ability to inform policy and program decisions.  OBJECTIVES: To explore what methods systematic reviewers use to consider health equity in systematic reviews of effectiveness.

SEARCH METHODS

We searched the following databases up to 26 February 2021: MEDLINE, PsycINFO, the Cochrane Methodology Register, CINAHL, Education Resources Information Center, Education Abstracts, Criminal Justice Abstracts, Hein Index to Foreign Legal Periodicals, PAIS International, Social Services Abstracts, Sociological Abstracts, Digital Dissertations and the Health Technology Assessment Database. We searched SCOPUS to identify articles that cited any of the included studies on 10 June 10 2021. We contacted authors and searched the reference lists of included studies to identify additional potentially relevant studies.

SELECTION CRITERIA

We included empirical studies of cohorts of systematic reviews that assessed methods for measuring effects on health inequalities. We define health inequalities as unfair and avoidable differences across socially stratifying factors that limit opportunities for health. We operationalised this by assessing studies which evaluated differences in health across any component of the PROGRESS-Plus acronym, which stands for Place of residence, Race/ethnicity/culture/language, Occupation, Gender or sex, Religion, Education, Socioeconomic status, Social capital. "Plus" stands for other factors associated with discrimination, exclusion, marginalisation or vulnerability such as personal characteristics (e.g. age, disability), relationships that limit opportunities for health (e.g. children in a household with parents who smoke) or environmental situations which provide limited control of opportunities for health (e.g. school food environment).

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data using a pre-tested form. Risk of bias was appraised for included studies according to the potential for bias in selection and detection of systematic reviews.  MAIN RESULTS: In total, 48,814 studies were identified and the titles and abstracts were screened in duplicate. In this updated review, we identified an additional 124 methodological studies published in the 10 years since the first version of this review, which included 34 studies. Thus, 158 methodological studies met our criteria for inclusion. The methods used by these studies focused on evidence relevant to populations experiencing health inequity (108 out of 158 studies), assess subgroup analysis across PROGRESS-Plus (26 out of 158 studies), assess analysis of a gradient in effect across PROGRESS-Plus (2 out of 158 studies) or use a combination of subgroup analysis and focused approaches (20 out of 158 studies). The most common PROGRESS-Plus factors assessed were age (43 studies), socioeconomic status in 35 studies, low- and middle-income countries in 24 studies, gender or sex in 22 studies, race or ethnicity in 17 studies, and four studies assessed multiple factors across which health inequity may exist. Only 16 studies provided a definition of health inequity. Five methodological approaches to consider health equity in systematic reviews of effectiveness were identified: 1) descriptive assessment of reporting and analysis in systematic reviews (140 of 158 studies used a type of descriptive method); 2) descriptive assessment of reporting and analysis in original trials (50 studies); 3) analytic approaches which assessed differential effects across one or more PROGRESS-Plus factors (16 studies); 4) applicability assessment (25 studies) and 5) stakeholder engagement (28 studies), which is a new finding in this update and examines the appraisal of whether relevant stakeholders with lived experience of health inequity were included in the design of systematic reviews or design and delivery of interventions. Reporting for both approaches (analytic and applicability) lacked transparency and was insufficiently detailed to enable the assessment of credibility.

AUTHORS' CONCLUSIONS

There is a need for improvement in conceptual clarity about the definition of health equity, describing sufficient detail about analytic approaches (including subgroup analyses) and transparent reporting of judgments required for applicability assessments in order to consider health equity in systematic reviews of effectiveness.

Primary health-care goal and principles

Primary health care (PHC) is targeted to ensure the highest possible level of health and well-being and their equitable distribution by concentrating on the public needs for a sustainable healthy life without any financial burden on patients. It is also explained how to give special preference to women, families, and rural communities on a priority basis. The most impressive part of this chapter is the role of PHC in handling the COVID-19 pandemic, which is still beyond perfect control. In this connection, the role of WHO to bring preventive measures at the state and country level is also well explained.

Economic Aspects of Delivering Primary Care Services: An Evidence Synthesis to Inform Policy and Research Priorities

Policy Points The 2018 Declaration of Astana reemphasized the importance of primary health care and its role in achieving universal health coverage. While there is a large amount of literature on the economic aspects of delivering primary care services, there is a need for more comprehensive overviews of this evidence. In this article, we offer such an overview. Evidence suggests that there are several strategies involving coverage, financing, service delivery, and governance arrangements which can, if implemented, have positive economic impacts on the delivery of primary care services. These include arrangements such as worker task-shifting and telemedicine. The implementation of any such arrangements, based on positive economic evidence, should carefully account for potential impacts on overall health care access and quality. There are many opportunities for further research, with notable gaps in evidence on the impacts of increasing primary care funding or the overall supply of primary care services.

CONTEXT

The 2018 Declaration of Astana reemphasized the importance of primary health care and its role in achieving universal health coverage. To strengthen primary health care, policymakers need guidance on how to allocate resources in a manner that maximizes its economic benefits.

METHODS

We collated and synthesized published systematic reviews of evidence on the economic aspects of different models of delivering primary care services. Building on previous efforts, we adapted existing taxonomies of primary care components to classify our results according to four categories: coverage, financing, service delivery, and governance.

FINDINGS

We identified and classified 109 reviews that met our inclusion criteria according to our taxonomy of primary care components: coverage, financing, service delivery, and governance arrangements. A significant body of evidence suggests that several specific primary care arrangements, such as health workers' task shifting and telemedicine, can have positive economic impacts (such as lower overall health care costs). Notably absent were reviews on the impact of increasing primary care funding or the overall supply of primary care services.

CONCLUSIONS

There is a great opportunity for further research to systematically examine the broader economic impacts of investing in primary care services. Despite progress over the last decade, significant evidence gaps on the economic implications of different models of primary care services remain, which could help inform the basis of future research efforts.

An Overview of Systematic Reviews of Chinese Herbal Medicine for Alzheimer's Disease

Background: Multiple systematic reviews (SRs) have been conducted to evaluate the efficacy and safety of Chinese herbal medicine (CHM) in patients with Alzheimer's disease (AD). Here, we aim to perform an overview to assess the methodological quality and quality of evidence of the SRs to provide convincing data on the treatment of AD with CHM. Method: Six electronic databases including Chinese and English were searched, until April 31, 2021. Two researchers independently screen documents and extract data according to the predesigned rules. A Measure Tool to Assessment System Reviews 2 (AMSTAR-2) was used to investigate the methodological quality, and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to determine the quality of evidence for outcomes. Results: Twelve qualified SRs including 163 randomized controlled trials were reviewed. The methodological quality of the included SRs was considered extremely low assessed through AMSTAR-2. Compared with western medicines (WM) alone, CHM as an adjuvant treatment has shown significant effects in improving Mini-mental State Examination, Alzheimer's Disease Assessment Scale-Cognitive, and Clinical Dementia Rating scores. The same is true for CHM alone. Regarding the effect on Activities Daily Living, neither the single CHM nor the combination with WM has an obvious effect. For the total effective rate, both single CHM and the combination with WM shown significant effects. Nine SRs suggested that CHM as adjuvant therapy or single-use had fewer adverse events than WM. Additionally, the quality of evidence for the main outcome was reviewed as low or extremely low according to GRADE profiler data. Conclusion: Current evidence suggests that CHM may be beneficial in improving the cognitive function of AD patients. However, we should be cautious about the evidence due to methodological flaws and low quality. High-quality RCTs are further needed to confirm the efficacy and safety of CHM for AD.

Revisiting the four core functions (4Cs) of primary care: operational definitions and complexities

BACKGROUND

The four primary care (PC) core functions (the '4Cs', ie, first contact, comprehensiveness, coordination and continuity) are essential for good quality primary healthcare and their achievement leads to lower costs, less inequality and better population health. However, their broad definitions have led to variations in their assessment, in the innovations implemented to improve these functions and ultimately in their performance.

OBJECTIVES

To update and operationalise the 4Cs' definitions by using a literature review and analysis of enhancement strategies, and to identify innovations that may lead to their enhancement.

METHODS

Narrative, descriptive analysis of the 4Cs definitions, coming from PC international reports and organisations, to identify measurable features for each of these functions. Additionally, we performed an electronic search and analysis of enhancement strategies to improve these four Cs, to explore how the 4Cs inter-relate.

RESULTS

Specific operational elements for first contact include modality of contact, and conditions for which PC should be approached; for comprehensiveness, scope of services and spectrum of population needs; for coordination, links between PC and higher levels of care and social/community-based services, and workforce managing transitions and for continuity, type, level and context of continuity. Several innovations like enrolment, digital health technologies and new or enhanced PC provider's roles, simultaneously influenced two or more of the 4Cs.

CONCLUSION

Providing clear, well-defined operational elements for these 4Cs to measure their achievement and improve the way they function, and identifying the complex network of interactions among them, should contribute to the field in a way that supports efforts at practice innovation to optimise the processes and outcomes in PC.

Primary Care Networks and Starfield's 4Cs: A Case for Enhanced Chronic Disease Management

The primary care network (PCN) was implemented as a healthcare delivery model which organises private general practitioners (GPs) into groups and furnished with a certain level of resources for chronic disease management. A secondary qualitative analysis was conducted with data from an earlier study exploring facilitators and barriers GPs enrolled in PCN's face in chronic disease management. The objective of this study is to map features of PCN to Starfield's "4Cs" framework. The "4Cs" of primary care-comprehensiveness, first contact access, coordination and continuity-offer high-quality design options for chronic disease management. Interview transcripts of GPs (n = 30) from the original study were purposefully selected. Provision of ancillary services, manpower, a chronic disease registry and extended operating hours of GP practices demonstrated PCN's empowering features that fulfil the "4Cs". On the contrary, operational challenges such as the lack of an integrated electronic medical record and disproportionate GP payment structures limit PCNs from maximising the "4Cs". However, the enabling features mentioned above outweighs the shortfalls in all important aspects of delivering optimal chronic disease care. Therefore, even though PCN is in its early stage of development, it has shown to be well poised to steer GPs towards enhanced chronic disease management.

Cervical cancer screening invitations in low and middle income countries: Evidence from Armenia

Roughly 90 percent of cervical cancer deaths occur in low- and middle-income countries (LMICs), where the lack of adequate infrastructures hampers screening, while informational, cultural, and socio-economic barriers limit participation in the few programs that do exist. We conducted a field experiment with the Armenian cervical cancer screening program to determine whether, despite these barriers, the simple, economical invitation strategies adopted in high-income countries could enhance screening take-up in LMICs. We find that letters of invitation increase screening take-up, especially when there are follow-up reminders. Different ways of framing messages appear to have no impact. Finally, women in rural areas are more likely to respond to invitation by letter, helping to narrow the urban-rural screening gap.

Evidence for the Use of Triage, Respiratory Isolation, and Effective Treatment to Reduce the Transmission of Mycobacterium Tuberculosis in Healthcare Settings: A Systematic Review

Evidence is limited for infection prevention and control (IPC) measures reducing Mycobacterium tuberculosis (MTB) transmission in health facilities. This systematic review, 1 of 7 commissioned by the World Health Organization to inform the 2019 update of global tuberculosis (TB) IPC guidelines, asked: do triage and/or isolation and/or effective treatment of TB disease reduce MTB transmission in healthcare settings? Of 25 included articles, 19 reported latent TB infection (LTBI) incidence in healthcare workers (HCWs; absolute risk reductions 1%-21%); 5 reported TB disease incidence in HCWs (no/slight [high TB burden] or moderate [low burden] reduction) and 2 in human immunodeficiency virus-positive in-patients (6%-29% reduction). In total, 23/25 studies implemented multiple IPC measures; effects of individual measures could not be disaggregated. Packages of IPC measures appeared to reduce MTB transmission, but evidence for effectiveness of triage, isolation, or effective treatment, alone or in combination, was indirect and low quality. Harmonizing study designs and reporting frameworks will permit formal data syntheses and facilitate policy making.

A nationally quasi-experimental study to assess the impact of partial organized breast and cervical cancer screening programme on participation and inequalities

BACKGROUND

Organized breast and cervical cancer screening programme could only provide services at no cost for a fraction of socioeconomic-deprived women in China and other low-resource countries, however, little evidence exists for whether such a programme effectively affect the participation and inequalities at the population level.

METHODS

We used individual-level data from a nationally cross-sectional survey in 2014-2015 for breast and cervical cancer screening participation. Data for intervention and comparison grouping were from 2009 to 2014 national breast and cervical cancer screening programme, and counties covered by the programme were divided into intervention group. We assessed the impact of the intervention on the participation rates and the magnitude of inequalities with two approaches: multivariable multilevel logistic regressions adjusting for individual- and region-level covariates; and a difference analysis combined with propensity score matching that estimated the average intervention effect.

RESULTS

Of 69,875 included women aged 35-64 years, 21,620 were classified into the intervention group and 43,669 into the comparison group for breast cancer screening; and 31,794 into the intervention group, and 33,682 into the comparison group for cervical cancer screening. Participation rate was higher in intervention group than comparison group for breast cancer screening (25.3, 95% confidential interval [CI], 22.8-27.7%, vs 19.1, 17.4-20.7%), and cervical cancer screening (25.7, 23.8-27.7%, vs 21.5, 19.6-23.5%), respectively. Intervention significantly increased the likelihood of participation for both breast cancer and cervical cancer screening in overall women, rural women and urban women, whereas the effect was significantly higher in rural women than urban women. The average intervention effect on the participation rate was an increase of 7.5% (6.7-8.2%) for breast cancer screening, and 6.8% (6.1-7.5%) for cervical cancer screening, respectively. The inequalities were significantly decreased by 37-41% (P < 0.001) between rural and urban, however, were slightly decreased or even increased in terms of age, education status, and household income.

CONCLUSIONS

Organized breast and cervical cancer screening programme targeting for a fraction of women could increase the participation rates at population level, however, it could not significantly affect socioeconomic-introduced inequalities. Further studies are need to conduct time-series analyses and strengthen the causal correlation.

'Our village is dependent on us. That's why we can't leave our work'. Characterizing mechanisms of motivation to perform among Accredited Social Health Activists (ASHA) in Bihar

Community health workers (CHWs) play major roles in delivering primary healthcare services, linking communities to the formal health system and addressing the social determinants of health. Available evidence suggests that the performance of CHW programmes in low- and middle-income countries can be influenced by context-dependent causal mechanisms such as motivation to perform. There are gaps regarding what these mechanisms are, and what their contribution is to CHW performance. We used a theory-driven case study to characterize motivational mechanisms among Accredited Social Health Activists (ASHAs) in Bihar, India. Data were collected through semi-structured interviews with CHWs and focus group discussions with beneficiary women. Data were coded using a combined deductive and inductive approach. We found that ASHAs were motivated by a sense of autonomy and self-empowerment; a sense of competence, connection and community service; satisfaction of basic financial needs; social recognition; and feedback and answerability. Findings highlight the potential of ASHAs' intrinsic motivation to increase their commitment to communities and identification with the health system and of programme implementation and management challenges as sources of work dissatisfaction. Efforts to nurture and sustain ASHAs' intrinsic motivation while addressing these challenges are necessary for improving the performance of Bihar's ASHA programme. Further research is needed to characterize the dynamic interactions between ASHAs' motivation, commitment, job satisfaction and overall performance; also, to understand how work motivation is sustained or lost through time. This can inform policy and managerial reforms to improve ASHA programme's performance.

Impact of average temperature, energy demand, sectoral value added, and population growth on water resource quality and mortality rate: it is time to stop waiting around

It is an overwhelming concern that increases in global average temperature lead to serious consequences on the natural environment in the form of deteriorating water resource quality and damaging healthcare sustainability agenda. The sustainable innovation forum (COP21) shows a high concern on climate changes and suggested to reduce global average temperature less than 2 °C. The study brings an idea from the stated theme and analyzed the relationship between climate change and water resource quality in order to redesign economic and environmental policies to improve water quality and healthcare sustainability in the context of Pakistan. The country has serious issues regarding the provision of safe drinking water, improved water resource quality, and healthcare sustainability, which can be achieved by sustainable policies to handle the extreme temperature in Pakistan. The study employed simultaneous generalized method of moments (GMM) technique in order to estimate parameters of the study during the period of 1980-2016. The results show that energy demand and industry value added substantially decrease water resource quality (WRQ), while agriculture value added and per capita income significantly increase WRQ in a country. The other regression apparatus, where health expenditures serve as the response variable, shows that average temperature, industry value added, population growth, and foreign direct investment (FDI) inflows significantly increase healthcare expenditures while WRQ has a negative impact on healthcare expenditures in a country. The final regression model shows that average temperature and per capita income decrease, while WRQ and industrial value added increase mortality rate in a country. The overall results confirm that WRQ affected by climate change, energy demand, and population growth that need sustainable water resource policies in order to achieve long-term sustained growth. The climate actions required more policy instruments to combat environmental challenges that should support healthcare sustainability agenda across the globe.

Improving the usefulness of evidence concerning the effectiveness of implementation strategies for knowledge products in primary healthcare: protocol for a series of systematic reviews

BACKGROUND

The literature on the implementation of knowledge products is extensive. However, this literature is still difficult to interpret for policymakers and other stakeholders when faced with choosing implementation strategies likely to bring about successful change in their health systems. This work has the particularity to examine the scope of this literature, and to clarify the effectiveness of implementation strategies for different knowledge products. Consequently, we aim to (1) determine the strengths and weaknesses of existing literature overviews; (2) produce a detailed portrait of the literature on implementation strategies for various knowledge products; and (3) assess the effectiveness of implementation strategies for each knowledge product identified and classify them.

METHODS

We will use a three-phase approach consisting of a critical analysis of existing literature overviews, a systematic review of systematic reviews, and a series of systematic reviews and meta-analyses. We will follow the Cochrane Methodology for each of the three phases. Our eligibility criteria are defined following a PICOS approach: Population, individuals or stakeholders participating in healthcare delivery, specifically, healthcare providers, caregivers, and end users; Intervention, any type of strategy aiming to implement a knowledge product including, but not limited to, a decision support tool, a clinical practice guideline, a policy brief, or a decision-making tool, a one-pager, or a health intervention; Comparison, any comparator will be considered; Outcomes, phases 1 and 2-any outcome related to implementation strategies including, but not limited to, the measures of adherence/fidelity to the use of knowledge products, their acceptability, adoption, appropriateness, feasibility, adaptability, implementation costs, penetration/reach and sustainability; phase 3-any additional outcome related to patients (psychosocial, health behavioral, and clinical outcomes) or healthcare professionals (behavioral and performance outcomes); Setting, primary healthcare has to be covered. We will search MEDLINE (Ovid), EMBASE, Web of Science, PsycINFO, CINAHL, and the Cochrane Library from their inception onwards. For each phase, two reviewers will independently perform the selection of studies, data extraction, and assess their methodological quality. We will analyze extracted data, and perform narrative syntheses, and meta-analyses when possible.

DISCUSSION

Our results could inform not only the overviews' methodology but also the development of an online platform for the implementation strategies of knowledge products. This platform could be useful for stakeholders in implementation science.

Going operational with health systems governance: supervision and incentives to health workers for increased quality of care in Tanzania

Improving the quality of care is increasingly recognized as a priority of health systems in low- and middle-income countries. Given the labour-intensive nature of healthcare interventions, quality of care largely depends upon the number, training and management of health workers involved in service delivery. Policies available to boost the performance of health workers-and thus the quality of healthcare-include regulation, incentives and supervision-all of which are typically included in quality improvement frameworks and policies. This was the case in Tanzania, where we assessed the role of selected quality improvement policies. To do so, we analysed data from a representative sample of Tanzanian government-managed health facilities, part of the 2014/15 Service Provision Assessment component of the Demographic and Health Survey. We constructed two healthcare quality indicators from data on patient visits: (1) compliance with Integrated Management of Childhood Illness (IMCI) guidelines and (2) patient satisfaction. Using multilevel ordered logistic regression models, we estimated the associations between the outcomes and selected indicators of incentives and supervisory activity at health worker and health facility level. We did not identify any association for the different indicators of top-down supervision at facility and individual level, neither with IMCI compliance nor with patients' satisfaction. Bottom-up supervision, defined as meetings between community and health facility staff, was significantly associated with higher patient satisfaction. Financial incentives in the form of salary top-ups were positively associated with both IMCI compliance and patient satisfaction. Both housing allowances and government-subsidized housing were positively associated with our proxies of quality of care. Good healthcare quality is crucial for promoting health in Tanzania not only through direct outcomes of the process of care but also through increased care-seeking behaviour in the communities. The results of this study highlight the role of community involvement, better salary conditions and housing arrangements for health workers.

Exploring the influencing factors for non-utilisation of healthcare facilities during childbirth: a special mixed-method study of Bangladesh and 13 other low- and middle-income countries based on Demographic and Health Survey data

OBJECTIVE

To identify the associated factors affecting the decision regarding institutional delivery for pregnant women in 14 low- and middle-income countries (LMICs).

DESIGN

A special mixed-method design was used to combine cross-sectional studies for harmonising data from Bangladesh and 13 other countries to obtain extended viewpoints on non-utilisation of institutional healthcare facilities during childbirth.

SETTING

Demographic and Health Survey (DHS) data for 14 LMICs were used for the study.

PARTICIPANTS

There are several kinds of datasets in the DHS. Among them 'Individual Women's Records' was used as this study is based on all ever-married women.

RESULTS

In the binary logistic and meta-analysis models for Bangladesh, ORs for birth order were 0.57 and 0.51 and for respondents' age were 1.50 and 1.07, respectively. In all 14 LMICs, the most significant factors for not using institutional facilities during childbirth were respondents' age (OR 0.903, 95% CI 0.790 to 1.032) and birth order (OR 0.371, 95% CI 0.327 to 0.421).

CONCLUSION

Birth order and respondents' age were the two most significant factors for non-utilisation of healthcare facilities during childbirth in 14 LMICs.

Antenatal care in rural Bangladesh: current state of costs, content and recommendations for effective service delivery

Background

Measurement of antenatal care (ANC) service coverage is often limited to the number of contacts or type of providers, reflecting a gap in the assessment of quality as well as cost estimations and health impact. The study aims to determine service subcomponents and provider and patient costs of ANC services and compares them between community (i.e. satellite clinics) and facility care (i.e. primary and secondary health centers) settings in rural Bangladesh.

Methods

Service contents and cost data were collected by one researcher and four interviewers in various community and facility health care settings in Gaibandha district between September and December 2016. We conducted structured interviews with organization managers, observational studies of ANC service provision (n = 70) for service contents and provider costs (service and drug costs) and exit interviews with pregnant women (n = 70) for patient costs (direct and indirect costs) in health clinics at community and facility levels. Fisher’s exact tests were used to determine any different patient characteristics between community and facility settings. ANC service contents were assessed by 63 subitems categorized into 11 groups and compared within and across community and facility settings. Provider and patient costs were collected in Bangladesh taka and analyzed as 2016 US Dollars (0.013 exchange rate).

Results

We found generally similar provider and patient characteristics between the community and facility settings except in clients’ gestational age. High compliance (> 50%) of service subcomponents were observed in blood pressure monitoring, weight measurement, iron and folate supplementation given, and tetanus vaccine, while lower compliance of service subcomponents (< 50%) were observed in some physical examinations such as edema and ultrasonogram and routine tests such as blood test and urine test. Average unit costs of ANC service provision were about double at the facility level ($2.75) compared with community-based care ($1.62). ANC patient costs at facilities ($2.66) were about three times higher than in the community ($0.78).

Conclusion

The study reveals a delay in pregnant women’s initial ANC care seeking, gaps in compliance of ANC subcomponents and difference of provider and patient costs between facility and community settings.

Evidence gap map of performance measurement and management in primary healthcare systems in low-income and middle-income countries

Introduction

We mapped available evidence on performance measurement and management (PMM) strategies in primary healthcare (PHC) systems of low-income and middle-income countries (LMICs). Widely used, their effectiveness remains inconclusive. This evidence gap map characterises existing research and evidence gaps.

Methods

Systematic mapping of performance measurement and management research in LMICs from 2000 to mid-2018; literature searches of seven academic databases and institutional repositories of impact evaluations and systematic reviews. Using a combination of manual screening and machine learning, four reviewers appraised 38 088 titles and abstracts, and extracted metadata from 137 impact evaluations and 18 systematic reviews that met the inclusion criteria. The resulting visual representation of the evidence base was uploaded to a web-based platform.

Results

Since 2000, the number of studies has increased; the first systematic reviews were completed in 2010. Two-thirds of the studies were conducted in sub-Saharan Africa and South Asia. Randomised controlled trials were the most frequently used study design. The evidence is concentrated in two types of PMM strategies: implementation strategies (in-service training, continuing education, supervision) and performance-based financing. Major gaps exist in accountability arrangements particularly the use of audit and feedback. The least studied types of outcomes were unintended effects, harm and social equity.

Conclusions

The evidence is clustered around interventions that are unlikely to achieve transformational change in health outcomes. The gaps identified suggest that routinely used PMM strategies are implemented without sufficient knowledge of their effects. Future efforts at redesigning PHC systems need to be informed by evidence on the most effective approaches for using PMM strategies.

Organisation of primary health care in the Asia-Pacific region: developing a prioritised research agenda

Health system planners in low- and middle-income countries (LMIC) of the Asia-Pacific region seeking to reorient primary health care (PHC) systems to achieve universal health coverage may be hindered by lack of knowledge of what works in their setting. With limited resources for research available, it is important to identify evidence-based strategies for reorganising PHC delivery, determine where relevant evidence gaps exist and prioritise these for future study. This paper describes an approach for doing this using the best available evidence combined with consultation to establish evidence priorities. We first reviewed PHC organisational interventions in Asia-Pacific LMICs and ascertained evidence gaps. The largest gaps related to interventions to promote access to essential medicines, patient management tools, effective health promotion strategies and service planning and accountability. Evidence from Pacific Island countries was particularly scant. We then engaged an expert panel of 22 PHC stakeholders from seven Asia-Pacific LMICs in a Delphi exercise to identify priority questions for future research. Research priorities were: (1) identifying effective PHC service delivery models for chronic diseases; (2) devising sustainable models of disease integration; (3) optimising task shifting; (4) understanding barriers to care continuity; (5) projecting future PHC needs; and (6) designing appropriate PHC service packages. Notably, stakeholder-determined priorities reflected large, context-dependent system issues, while evidence gaps centred on discrete interventions. Future research on the organisation of PHC services in Asia-Pacific LMICs should incorporate codesign principles to engage researchers and national PHC system stakeholders, and innovative methods that build on existing evidence and account for system complexity.

Integration of schistosomiasis control activities within the primary health care system: a critical review

Background

Schistosomiasis is a chronic disease linked to poverty and is widely endemic, particularly in sub-Saharan Africa. For decades, the World Health Organization has called for a larger role of the primary health care system in schistosomiasis control, and its integration within the routine activities of primary health care facilities. Here, we reviewed existing studies on the integration of schistosomiasis control measures within the primary health care system, more precisely at the health centre, and we analysed their outcomes.

Methods

An online search of studies published via PubMed and Embase databases was carried out until December 2017. Keywords were used to identify articles related to the integration of schistosomiasis control within the primary health care system, especially at the health centre level. Studies on integration of the following control measures were included: diagnosis and treatment, supplemented or not with (i) health education; (ii) snail control; and (iii) clean water supply and sanitation. A qualitative review was undertaken. To conclude on the effectiveness of an intervention, intermediate outcomes (knowledge, attitude and practice, coverage, access to health care) and distal outcomes (prevalence, incidence, mortality) were considered, and pre/post-intervention results were compared.

Results

Of 569 records found, 11 met the inclusion criteria. Studies were classified in three groups, according to the control measures they included. Integration of diagnosis and treatment, and health education in the first group resulted in an improvement of knowledge level of care providers, access to health care and health care seeking behaviour of the community. However, no positive effect was observed on the knowledge level of symptoms and modes of transmission at the community level. Most studies in the second group (with snail control as additional measure) and the third group (with clean water supply and sanitation as additional measure) showed a positive effect on schistosomiasis prevalence and incidence post-intervention, independent of the additional control measures implemented.

Conclusions

The results of this review suggest a positive impact of integration of schistosomiasis control within the primary health care system. However, more robust studies are needed, especially in resource-limited regions, for conclusive evidence on the effectiveness and the sustainability of this strategy.

Clinical emergency care research in low-income and middle-income countries: opportunities and challenges

Disease processes that frequently require emergency care constitute approximately 50% of the total disease burden in low-income and middle-income countries (LMICs). Many LMICs continue to deal with emergencies caused by communicable disease states such as pneumonia, diarrhoea, malaria and meningitis, while also experiencing a marked increase in non-communicable diseases, such as cardiovascular diseases, diabetes mellitus and trauma. For many of these states, emergency care interventions have been developed through research in high-income countries (HICs) and advances in care have been achieved. However, in LMICs, clinical research, especially interventional trials, in emergency care are rare. Furthermore, there exists minimal research on the emergency management of diseases, which are rarely encountered in HICs but impact the majority of LMIC populations. This paper explores challenges in conducting clinical research in patients with emergency conditions in LMICs, identifies examples of successful clinical research and highlights the system, individual and study design characteristics that made such research possible in LMICs. Derived from the available literature, a focused list of high impact research considerations are put forth.

Socioeconomic factors associated with choice of delivery place among mothers: a population-based cross-sectional study in Guinea-Bissau

Background

Maternal death outcome remains high in Guinea-Bissau. Delivery-related complications and maternal mortality could be prevented by increasing women's access to skilled pregnancy care. Socioeconomic status (SES) is often associated with low health service utilisation in low/middle-income countries. In Guinea-Bissau, little is known on the relationship between SES and use of health facility for delivery. In this study, we examined the association between women's choice of health facility delivery with their SES.

Methods

Current data from Multiple Indicator Cluster Survey conducted in Guinea-Bissau, 2014 were used in this study. The place of delivery (home or health facility) was the outcome variable of interest using 7532 women of reproductive age (15-49 years). Respondents' characteristics were described by summary statistics, while multivariable logistic regression model was used to examine the association of demographic and socioeconomic characteristics on facility-based delivery. Adjusted ORs, 95% CIs and p values were computed to identify significant determinants.

Results

Results show that in proportion of women delivering at home was higher than of delivery at a health facility. Overall percentage of women who delivered at health facility was 39.8%, with the rate being substantially higher among urban (67.8%) compared with their rural (30.2%) counterparts. Percentage of delivering at home was highest in Oio region (23.8%) and that of delivery at a health facility was highest in the Sector Autónomo de Bissau region (18.7%). In the multivariable analysis, women in urban areas compared those who had no education, those who had primary and secondary/higher level of education were 2.2 and 3.3 times more likely to deliver at a health facility. The odds of facility were also highest among the women from the richest households, 5.3 and 5 times among urban and rural women, respectively.

Conclusion

Based on these findings, the study concludes that the percentage of health facility delivery is low in Guinea-Bissau, which can be promoted through scaling up women's SES. The findings could guide healthcare policy-makers to address the issue of unskilled delivery services and increase the use of facility-based delivery particularly among the disadvantaged women.

The meaning of "socialization of health" to Iranian policymakers and how it can be implemented

Complex nature of health and disease, the impact of various socioeconomic factors on the health system arrangements and health of the society, and also the impact of health on the social and economic conditions of the society require a social approach to health. This necessity has led to the creation of new policies and programs, under the name of socialization of health, to strengthen the social approach to health in the health system of Iran. However, there must be more convergence between various stakeholders about the definition, conceptual framework, and different dimensions of this term (socialization of health). Using the experts' opinions and scientific evidence, we clarified the concepts and different dimensions of socialization of health to be used by healthcare policymakers and managers.

Integrated HIV-Care Into Primary Health Care Clinics and the Influence on Diabetes and Hypertension Care: An Interrupted Time Series Analysis in Free State, South Africa Over 4 Years

BACKGROUND

Noncommunicable diseases (NCDs), specifically diabetes and hypertension, are rising in high HIV-burdened countries such as South Africa. How integrated HIV care into primary health care (PHC) influences NCD care is unknown. We aimed to understand whether differences existed in NCD care (pre- versus post-integration) and how changes may relate to HIV patient numbers.

SETTING

Public sector PHC clinics in Free State, South Africa.

METHODS

Using a quasiexperimental design, we analyzed monthly administrative data on 4 indicators for diabetes and hypertension (clinic and population levels) during 4 years as HIV integration was implemented in PHC. Data represented 131 PHC clinics with a catchment population of 1.5 million. We used interrupted time series analysis at ±18 and ±30 months from HIV integration in each clinic to identify changes in trends postintegration compared with those in preintegration. We used linear mixed-effect models to study relationships between HIV and NCD indicators.

RESULTS

Patients receiving antiretroviral therapy in the 131 PHC clinics studied increased from 1614 (April 2009) to 57, 958 (April 2013). Trends in new diabetes patients on treatment remained unchanged. However, population-level new hypertensives on treatment decreased at ±30 months from integration by 6/100, 000 (SE = 3, P < 0.02) and was associated with the number of new patients with HIV on treatment at the clinics.

CONCLUSIONS

Our findings suggest that during the implementation of integrated HIV care into PHC clinics, care for hypertensive patients could be compromised. Further research is needed to understand determinants of NCD care in South Africa and other high HIV-burdened settings to ensure patient-centered PHC.

Willing but unable? Extending theory to investigate community capacity to participate in Ghana's community-based health planning and service implementation

While primary health care programmes based on community participation are widely implemented in low- and middle- income settings, empirical evidence on whether and to what extent local people have the capacity to participate, support and drive such programmes scale up is scant in these countries. This paper assessed the level of community capacity to participate in one such programme - the Community-Based Health Planning and Service (CHPS) in Ghana. The capacity assessments were drawn from Chaskin's (2001) theorised indicators of community capacity with modifications to include: sense of community; community members commitment; community leadership commitment; problem solving mechanisms; and access to resources. These capacity measures guided the design of an interview guide used to collect data from community informants, frontline health providers (FLP) and district health managers. Key qualitative themes were built into a questionnaire administered to households selected through systematic sampling approach. Findings showed that growing individualism, low trust in neighbours and apathetic behaviours undermined the capacity of mutual support for CHPS. The capacity to support CHPS was high for local leadership and community social mobilisation groups who often dedicated time to working with FLP to promote maternal and reproductive health service use, and in advocating broader support for CHPS. Within the wider community, commitment to voluntarism was low as members perceived CHPS to be owned by, and run on government funds and resources. Poor voluntarism was compounded by poverty that crippled the capacity to provide needed resource support for CHPS. Findings have great implications for building strong capable communities for participation in community oriented health programmes.

How good is collaboration between maternity service providers in the Netherlands?

AIMS

To examine the experiences of inter-professional collaboration of maternity service providers in the Netherlands and to identify potential enhancing and inhibiting factors for inter-professional collaboration within maternity care in the Netherlands.

BACKGROUND

Good collaboration between health care professionals is a key element of safe, effective care, but creating a collaborative culture can be challenging. Good collaboration requires, among other things, negotiating different professional orientations and the organizational constraints of hierarchies and scheduling. Good collaboration is especially important in maternity care. In the Netherlands, suboptimal collaboration has been cited as a significant factor in maternal deaths and in adverse incidents occurring in hospitals during evenings, nights, and weekends. In spite of its importance for effective maternity care, little is known about the nature and quality of collaboration between maternity care professionals. In order to fill this gap, we examined the inter-professional collaboration within multi-disciplinary teams (MDTs) providing maternity services in the Netherlands.

METHODS

Online survey of MDTs (consisting of hospital and PCMs, doctors, and carers) involved in the provision of maternity services in the Netherlands. We used a validated measure of collaboration (the Leiden Quality of Work Questionnaire) to analyze the attitudes of those involved in the provision of maternity services about multi-disciplinary collaboration in their work. We used descriptive and inferential statistics to assess differences between the groups.

RESULTS

40% of all respondents were not satisfied with collaboration within their MDT. Overall, mean collaboration scores (MCS) were low. We found significant differences in MCS between professional groups. Midwives - community and hospital based - were pessimistic about collaboration in future models of maternity care.

DISCUSSION

In the Netherlands, collaboration in maternity care is less than optimal. Poor collaboration is associated with negative consequences for patient safety and quality of care. Strategies to address suboptimal collaboration exist; however, no one-size-fits-all approach is identified in the literature.

CONCLUSION

Suboptimal collaboration exists within the midwifery model of care in the Netherlands and the relationship between care providers is under pressure. This could affect patient safety and quality of care, according to the literature.

PRÉCIS

This paper presents an in-depth examination of the nature of, and attitudes about, collaboration between members of the MDT involved in the provision of maternity services in the Netherlands.

Midwife-assisted planned home birth: an essential component of improving the safety of childbirth in Sub-Saharan Africa

Hospital births, when compared to out-of-hospital births, have generally led to not only a significantly reduced maternal and perinatal mortality and morbidity but also an increase in certain interventions. A trend seems to be emerging, especially in the US where some women are requesting home births, which creates ethical challenges for obstetricians and the health care organizations and policy makers. In the developing world, a completely different reality exists. Home births constitute the majority of deliveries in the developing world. There are severe limitations in terms of facilities, health personnel and deeply entrenched cultural and socio-economic conditions militating against hospital births. As a consequence, maternal and perinatal mortality and morbidity remain the highest, especially in Sub-Saharan Africa (SSA). Midwife-assisted planned home birth therefore has a major role to play in increasing the safety of childbirth in SSA. The objective of this paper is to propose a model that can be used to improve the safety of childbirth in low resource countries and to outline why midwife assisted planned home birth with coordination of hospitals is the preferred alternative to unassisted or inadequately assisted planned home birth in SSA.

Revisiting Alma-Ata: what is the role of primary health care in achieving the Sustainable Development Goals?

The Sustainable Development Goals (SDGs) are now steering the global health and development agendas. Notably, the SDGs contain no mention of primary health care, reflecting the disappointing implementation of the Alma-Ata declaration of 1978 over the past four decades. The draft Astana declaration (Alma-Ata 2·0), released in June, 2018, restates the key principles of primary health care and renews these as driving forces for achieving the SDGs, emphasising universal health coverage. We use accumulating evidence to show that countries that reoriente their health systems towards primary care are better placed to achieve the SDGs than those with hospital-focused systems or low investment in health. We then argue that an even bolder approach, which fully embraces the Alma-Ata vision of primary health care, could deliver substantially greater SDG progress, by addressing the wider determinants of health, promoting equity and social justice throughout society, empowering communities, and being a catalyst for advancing and amplifying universal health coverage and synergies among SDGs.

Institutional delivery in India, 2004-14: unravelling the equity-enhancing contributions of the public sector

To achieve faster and equitable improvements in maternal and child health outcomes, the government of India launched the National Rural Health Mission in 2005. This paper describes the equity-enhancing role of the public sector in increasing use of institutional delivery care services in India between 2004 and 2014. Information on 24 661 births from nationally representative survey data for 2004 and 2014 is analysed. Concentration index is computed to describe socioeconomic-rank-related relative inequalities in institutional delivery and decomposition is used to assess the contributions of public and private sectors in overall socioeconomic inequality. Multilevel logistic regression is applied to examine the changes in socioeconomic gradient between 2004 and 2014. The analysis finds that utilization of institutional delivery care in India increased from 43% in 2004 to 83% in 2014. The bulk of the increase was in public sector use (21% in 2004 to 53% in 2014) with a modest increase in private sector use (22% in 2004 to 30% in 2014). The shift from a pro-rich to pro-poor distribution of public sector use is confirmed. Decomposition analysis indicates that 51% of these reductions in socioeconomic inequality are associated with improved pro-poor distribution of public sector births. Multilevel logistic regressions confirm the disappearance of a wealth-based gradient in public sector births between 2004 and 2014. We conclude that public health investments in India have significantly contributed towards an equitable increase in the coverage of institutional delivery care. Sustained policy efforts are necessary, however, with an emphasis on education, sociocultural and geographical factors to ensure universal coverage of institutional delivery care services in India.

NCD Countdown 2030: worldwide trends in non-communicable disease mortality and progress towards Sustainable Development Goal target 3.4

The third UN High-Level Meeting on Non-Communicable Diseases (NCDs) on Sept 27, 2018, will review national and global progress towards the prevention and control of NCDs, and provide an opportunity to renew, reinforce, and enhance commitments to reduce their burden. NCD Countdown 2030 is an independent collaboration to inform policies that aim to reduce the worldwide burden of NCDs, and to ensure accountability towards this aim. In 2016, an estimated 40·5 million (71%) of the 56·9 million worldwide deaths were from NCDs. Of these, an estimated 1·7 million (4% of NCD deaths) occurred in people younger than 30 years of age, 15·2 million (38%) in people aged between 30 years and 70 years, and 23·6 million (58%) in people aged 70 years and older. An estimated 32·2 million NCD deaths (80%) were due to cancers, cardiovascular diseases, chronic respiratory diseases, and diabetes, and another 8·3 million (20%) were from other NCDs. Women in 164 (88%) and men in 165 (89%) of 186 countries and territories had a higher probability of dying before 70 years of age from an NCD than from communicable, maternal, perinatal, and nutritional conditions combined. Globally, the lowest risks of NCD mortality in 2016 were seen in high-income countries in Asia-Pacific, western Europe, and Australasia, and in Canada. The highest risks of dying from NCDs were observed in low-income and middle-income countries, especially in sub-Saharan Africa, and, for men, in central Asia and eastern Europe. Sustainable Development Goal (SDG) target 3.4-a one-third reduction, relative to 2015 levels, in the probability of dying between 30 years and 70 years of age from cancers, cardiovascular diseases, chronic respiratory diseases, and diabetes by 2030-will be achieved in 35 countries (19%) for women, and 30 (16%) for men, if these countries maintain or surpass their 2010-2016 rate of decline in NCD mortality. Most of these are high-income countries with already-low NCD mortality, and countries in central and eastern Europe. An additional 50 (27%) countries for women and 35 (19%) for men are projected to achieve such a reduction in the subsequent decade, and thus, with slight acceleration of decline, could meet the 2030 target. 86 (46%) countries for women and 97 (52%) for men need implementation of policies that substantially increase the rates of decline. Mortality from the four NCDs included in SDG target 3.4 has stagnated or increased since 2010 among women in 15 (8%) countries and men in 24 (13%) countries. NCDs and age groups other than those included in the SDG target 3.4 are responsible for a higher risk of death in low-income and middle-income countries than in high-income countries. Substantial reduction of NCD mortality requires policies that considerably reduce tobacco and alcohol use and blood pressure, and equitable access to efficacious and high-quality preventive and curative care for acute and chronic NCDs.

Who is the Woman in Women's Nutrition? A Narrative Review of Evidence and Actions to Support Women's Nutrition throughout Life

Nutrition interventions that target mothers alone inadequately address women's needs across their lives: during adolescence, preconception, and in later years of life. They also fail to capture nulliparous women. The extent to which nutrition interventions effectively reach women throughout the life course is not well documented. In this comprehensive narrative review, we summarized the impact and delivery platforms of nutrition-specific and nutrition-sensitive interventions targeting adolescent girls, women of reproductive age (nonpregnant, nonlactating), pregnant and lactating women, women with young children <5 y, and older women, with a focus on nutrition interventions delivered in low- and middle-income countries. We found that although there were many effective interventions that targeted women's nutrition, they largely targeted women who were pregnant and lactating or with young children. There were major gaps in the targeting of interventions to older women. For the delivery platforms, community-based settings, compared with facility-based settings, more equitably reached women across the life course, including adolescents, women of reproductive age, and older women. Nutrition-sensitive approaches were more often delivered in community-based settings; however, the evidence of their impact on women's nutritional outcomes was less clear. We also found major research and programming gaps relative to targeting overweight, obesity, and noncommunicable disease. We conclude that focused efforts on women during pregnancy and in the first couple of years postpartum fail to address the interrelation and compounding nature of nutritional disadvantages that are perpetuated across many women's lives. In order for policies and interventions to more effectively address inequities faced by women, and not only women as mothers, it is essential that they reflect on how, when, and where to engage with women across the life course.

Barriers and facilitators to implementation of essential health benefits package within primary health care settings in low-income and middle-income countries: A systematic review

BACKGROUND

One of the key requirements for achieving universal health coverage is the proper design and implementation of essential health benefits package (EHPs). We systematically reviewed the evidence on barriers and facilitators to the implementation of EHPs within primary health care settings in low-income and middle-income countries.

METHODS

We searched multiple databases and the gray literature. Two reviewers completed independently and in duplicate data selection, data extraction, and quality assessment. We synthesized the findings according to the following health systems arrangement levels: governance, financial, and delivery arrangements.

RESULTS

Ten studies met the eligibility criteria. At the governance level, key reported barriers were insufficient policymaker-implementer interactions, limited involvement of consumers and stakeholders, sub-optimal primary health care network arrangement, poor marketing and promotion of package, and insufficient coordination with community network. The key reported facilitator was the presence of a legal policy framework for package implementation. At the financial level, barriers included delays and inadequate remunerations to health care providers while facilitators included government and donor commitments to financing of package and flexibility in exploring new funding mechanisms. At the delivery level, barriers included inadequate supervision, poor facility infrastructure, limited availability of equipment and supplies, and shortages of workers. Facilitators included proper training and management of workforce, availability of female health workers, presence of clearly defined packages, and continuum of care, including referrals to promote comprehensive service delivery.

CONCLUSION

We identified a set of barriers and facilitators that need to be addressed to ensure proper implementation of EHPs within primary health care settings.

Supporting Indigenous families in the Cree territory: lessons from the  Mashkûpímâtsît Awash initiative

OBJECTIVE

We describe the adaptation of an early childcare and development program to the Indigenous context of the Cree territory in Québec. We also share lessons on the challenging implementation of home visits by Indigenous family support workers (FSWs), which is a critical component of the intervention.

PARTICIPANTS

 Mashkûpímâtsît Awash (AMA) aims to enhance the health and well-being of pregnant mothers, young children, and their families by providing intensive interdisciplinary care and follow-up. Indigenous female FSWs from the community are the key frontline workers and cornerstone of the program.

SETTING

AMA is implemented as part of the multidisciplinary services provided by the Community Miyupimaatisiiun Centres (primary health care centres) in three pilot communities of Eeyou Istchee.

INTERVENTION

AMA builds on family centredness and cultural safety, integration of services, and creation of family-friendly communities. It emphasizes the role of female local Indigenous FSWs in providing culturally safe outreach services in the form of home visits.

OUTCOMES

The main challenge was conducting home visits. FSWs' view of the pertinence of home visits, as well as their personal stories, seemed to influence their motivation to conduct home visits. Their level of experience appeared to facilitate home visits. Encouraging creativity, fostering autonomy, ensuring a step-by-step implementation, and promoting communication were found to create a supporting environment to facilitate home visits.

IMPLICATIONS

Hiring local Indigenous workers is necessary to ensure that early childhood development programs are culturally safe. Success of such programs relies on team management, provision of culturally adapted training, and quality of the ongoing emotional support provided to the FSWs.

Capacity gaps in health facilities for case management of intestinal schistosomiasis and soil-transmitted helminthiasis in Burundi

Background

Schistosomiasis and soil-transmitted helminthiasis (STH) are endemic diseases in Burundi. STH control is integrated into health facilities (HF) across the country, but schistosomiasis control is not. The present study aimed to assess the capacity of HF for integrating intestinal schistosomiasis case management into their routine activities. In addition, the current capacity for HF-based STH case management was evaluated.

Methods

A random cluster survey was carried out in July 2014, in 65 HF located in Schistosoma mansoni and STH endemic areas. Data were collected by semi-quantitative questionnaires. Staff with different functions at the HF were interviewed (managers, care providers, heads of laboratory and pharmacy and data clerks). Data pertaining to knowledge of intestinal schistosomiasis and STH symptoms, human and material resources and availability and costs of diagnostic tests and treatment were collected.

Findings

Less than half of the 65 care providers mentioned one or more major symptoms of intestinal schistosomiasis (abdominal pain 43.1%, bloody diarrhoea 13.9% and bloody stool 7.7%). Few staff members (15.7%) received higher education, and less than 10% were trained in-job on intestinal schistosomiasis case management. Clinical guidelines and laboratory protocols for intestinal schistosomiasis diagnosis and treatment were available in one third of the HF. Diagnosis was performed by direct smear only. Praziquantel was not available in any of the HF. The results for STH were similar, except that major symptoms were more known and cited (abdominal pain 69.2% and diarrhoea 60%). Clinical guidelines were available in 61.5% of HF, and albendazole or mebendazole was available in all HF.

Conclusions

The current capacity of HF for intestinal schistosomiasis and STH detection and management is inadequate. Treatment was not available for schistosomiasis. These issues need to be addressed to create an enabling environment for successful integration of intestinal schistosomiasis and STH case management into HF routine activities in Burundi for better control of these diseases.

Universal Health Coverage in Francophone Sub-Saharan Africa: Assessment of Global Health Experts' Confidence in Policy Options

Many countries rely on standard recipes for accelerating progress toward universal health coverage (UHC). With limited generalizable empirical evidence, expert confidence and consensus plays a major role in shaping country policy choices. This article presents an exploratory attempt conducted between April and September 2016 to measure confidence and consensus among a panel of global health experts in terms of the effectiveness and feasibility of a number of policy options commonly proposed for achieving UHC in low- and middle-income countries, such as fee exemptions for certain groups of people, ring-fenced domestic health budgets, and public-private partnerships. To ensure a relative homogeneity of contexts, we focused on French-speaking sub-Saharan Africa. We initially used the Delphi method to arrive at expert consensus, but since no consensus emerged after 2 rounds, we adjusted our approach to a statistical analysis of the results from our questionnaire by measuring the degree of consensus on each policy option through 100 (signifying total consensus) minus the size of the interquartile range of the individual scores. Seventeen global health experts from various backgrounds, but with at least 20 years' experience in the broad region, participated in the 2 rounds of the study. The results provide an initial "mapping" of the opinions of a group of experts and suggest interesting lessons. For the 18 policy options proposed, consensus emerged only on strengthening the supply of quality primary health care services (judged as being effective with a confidence score of 79 and consensus score of 90), and on fee exemptions for the poorest (judged as being fairly easy to implement with a confidence score of 66 and consensus score of 85). For none of the 18 common policy options was there consensus on both potential effectiveness and feasibility, with very diverging opinions concerning 5 policy options. The lack of confidence and consensus within the panel seems to reflect the lack of consistent evidence on the proposed policy options. This suggests that experts' opinions should be framed within strengthened inclusive and "evidence-informed deliberative processes" where the trade-offs along the 3 dimensions of UHC-extending the population covered against health hazards, expanding the range of services and benefits covered, and reducing out-of-pocket expenditures-can be discussed in a transparent and contextualized setting.

Cost-effectiveness of health care service delivery interventions in low and middle income countries: a systematic review

Background

Low and middle income countries (LMICs) face severe resource limitations but the highest burden of disease. There is a growing evidence base on effective and cost-effective interventions for these diseases. However, questions remain about the most cost-effective method of delivery for these interventions. We aimed to review the scope, quality, and findings of economic evaluations of service delivery interventions in LMICs.

Methods

We searched PUBMED, MEDLINE, EconLit, and NHS EED for studies published between 1st January 2000 and 30th October 2016 with no language restrictions. We included all economic evaluations that reported incremental costs and benefits or summary measures of the two such as an incremental cost effectiveness ratio. Studies were grouped by both disease area and outcome measure and permutation plots were completed for similar interventions. Quality was judged by the Drummond checklist.

Results

Overall, 3818 potentially relevant abstracts were identified of which 101 studies were selected for full text review. Thirty-seven studies were included in the final review. Twenty-three studies reported on interventions we classed as “changing by whom and where care was provided”, specifically interventions that entailed task-shifting from doctors to nurses or community health workers or from facilities into the community. Evidence suggests this type of intervention is likely to be cost-effective or cost-saving. Nine studies reported on quality improvement initiatives, which were generally found to be cost-effective. Quality and methods differed widely limiting comparability of the studies and findings.

Conclusions

There is significant heterogeneity in the literature, both methodologically and in quality. This renders further comparisons difficult and limits the utility of the available evidence to decision makers.

Systematic review and meta-analysis of global birth prevalence of clubfoot: a study protocol

INTRODUCTION

Clubfoot is a common congenital birth defect, with an average prevalence of approximately 1 per 1000 live births, although this rate is reported to vary among different countries around the world. If it remains untreated, clubfoot causes permanent disability, limits educational and employment opportunities, and personal growth. The aim of this systematic review and meta-analysis is to estimate the global birth prevalence of congenital clubfoot.

METHODS AND ANALYSIS

Electronic databases including MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Global Health, Latin American & Caribben Health Science Literature (LILACS), Maternity and Infant Care, Web of Science, Scopus and Google Scholar will be searched for observational studies based on predefined criteria and only in English language from inception of database in 1946 to 10 November 2017. A standard data extraction form will be used to extract relevant information from included studies. The Joanna Briggs Institute appraisal checklist will be used to assess the overall quality of studies reporting prevalence. All included studies will be assessed for risk of bias using a tool developed specifically for prevalence studies. Forest plots will be created to understand the overall random effects of pooled estimates with 95% CIs. An I2 test will be done for heterogeneity of the results (P>0.05), and to identify the source of heterogeneity across studies, subgroup or meta-regression will be used to assess the contribution of each variable to the overall heterogeneity. A funnel plot will be used to identify reporting bias, and sensitivity analysis will be used to assess the impact of methodological quality, study design, sample size and the impact of missing data.

ETHICS AND DISSEMINATION

This review will be conducted completely based on published data, so approval from an ethics committee or written consent will not be required. The results will be disseminated through a peer-reviewed publication and relevant conference presentations.

Ghana's community-based primary health care: Why women and children are 'disadvantaged' by its implementation

Policy analysis on why women and children in low- and middle-income settings are still disadvantaged by access to appropriate care despite Primary Health Care (PHC) programmes implementation is limited. Drawing on the street-level bureaucracy theory, we explored how and why frontline providers (FLP) actions on their own and in interaction with health system factors shape Ghana's community-based PHC implementation to the disadvantage of women and children accessing and using health services. This was a qualitative study conducted in 4 communities drawn from rural and urban districts of the Upper West region. Data were collected from 8 focus group discussions with community informants, 73 in-depth interviews with clients, 13 in-depth interviews with district health managers and FLP, and observations. Data were recorded, transcribed and coded deductively and inductively for themes with the aid of Nvivo 11 software. Findings showed that apart from FLP frequent lateness to, and absenteeism from work, that affected care seeking for children, their exercise of discretionary power in determining children who deserve care over others had ripple effects: families experienced financial hardships in seeking alternative care for children, and avoided that by managing symptoms with care provided in non-traditional spaces. FLP adverse behaviours were driven by weak implementation structures embedded in the district health systems. Basic obstetric facilities such as labour room, infusion stand, and beds for deliveries, detention and palpation were lacking prompting FLP to cope by conducting deliveries using a patchwork of improvised delivery methods which worked out to encourage unassisted home deliveries. Perceived poor conditions of service weakened FLP commitment to quality maternal and child care delivery. Findings suggest the need for strategies to induce behaviour change in FLP, strengthen district administrative structures, and improve on the supply chain and logistics system to address gaps in CHPS maternal and child care delivery.

Combining Best Practices and Patient, Caregiver, and Healthcare Provider Perspectives for Late-Life Supportive Care: LifeCourse

Healthcare systems seek effective ways to support and treat the growing number of individuals living with serious illness. The nature of these care episodes challenges delivery systems to attain proficiency in dealing with the multiplicity of chronic conditions in individuals and populations through understanding and attending to patients' medical and nonmedical aspects of health. This article describes LifeCourse, a healthcare approach that provides palliative care practices to patients with serious illness years prior to death.

Rationale for the prevention of oral diseases in primary health care: an international collaborative study in oral health education

Ensuring that members of society are healthy and reaching their full potential requires the prevention of oral diseases through the promotion of oral health and well-being. The present article identifies the best policy conditions of effective public health and primary care integration and the actors who promote and sustain these efforts. In this review, arguments and recommendations are provided to introduce an oral health collaborative promotion programme called Live.Learn.Laugh. phase 2, arising from an unique partnership between FDI World Dental Federation, the global company Unilever plc and an international network of National Dental Associations, health-care centres, schools and educators populations.

Implementation considerations when expanding health worker roles to include safe abortion care: a five-country case study synthesis

Background

Allowing a broader range of trained health workers to deliver services can be an important way of improving access to safe abortion care. However, the expansion of health worker roles may be challenging to implement. This study aimed to explore factors influencing the implementation of role expansion strategies for non-physician providers to include the delivery of abortion care.

Methods

We conducted a multi-country case study synthesis in Bangladesh, Ethiopia, Nepal, South Africa and Uruguay, where the roles of non-physician providers have been formally expanded to include the provision of abortion care. We searched for documentation from each country related to non-physician providers, abortion care services and role expansion through general internet searches, Google Scholar and PubMed, and gathered feedback from 12 key informants. We carried out a thematic analysis of the data, drawing on categories from the SURE Framework of factors affecting the implementation of policy options.

Results

Several factors appeared to affect the successful implementation of including non-physician providers to provide abortion care services. These included health workers’ knowledge about abortion legislation and services; and health workers’ willingness to provide abortion care. Health workers’ willingness appeared to be influenced by their personal views about abortion, the method of abortion and stage of pregnancy and their perceptions of their professional roles. While managers’ and co-workers’ attitudes towards the use of non-physician providers varied, the synthesis suggests that female clients focused less on the type of health worker and more on factors such as trust, privacy, cost, and closeness to home. Health systems factors also played a role, including workloads and incentives, training, supervision and support, supplies, referral systems, and monitoring and evaluation. Strategies used, with varying success, to address some of these issues in the study countries included values clarification workshops, health worker rotation, access to emotional support for health workers, the incorporation of abortion care services into pre-service curricula, and in-service training strategies.

Conclusions

To increase the likelihood of success for role expansion strategies in the area of safe abortion, programme planners must consider how to ensure motivation, support and reasonable working conditions for affected health workers.

Delivery arrangements for health systems in low-income countries: an overview of systematic reviews

BACKGROUND

Delivery arrangements include changes in who receives care and when, who provides care, the working conditions of those who provide care, coordination of care amongst different providers, where care is provided, the use of information and communication technology to deliver care, and quality and safety systems. How services are delivered can have impacts on the effectiveness, efficiency and equity of health systems. This broad overview of the findings of systematic reviews can help policymakers and other stakeholders identify strategies for addressing problems and improve the delivery of services.

OBJECTIVES

To provide an overview of the available evidence from up-to-date systematic reviews about the effects of delivery arrangements for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on delivery arrangements and informing refinements of the framework for delivery arrangements outlined in the review.

METHODS

We searched Health Systems Evidence in November 2010 and PDQ-Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of delivery arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use, healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty or employment) and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the findings. Two overview authors independently screened reviews, extracted data, and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence), and assessments of the relevance of findings to low-income countries.

MAIN RESULTS

We identified 7272 systematic reviews and included 51 of them in this overview. We judged 6 of the 51 reviews to have important methodological limitations and the other 45 to have only minor limitations. We grouped delivery arrangements into eight categories. Some reviews provided more than one comparison and were in more than one category. Across these categories, the following intervention were effective; that is, they have desirable effects on at least one outcome with moderate- or high-certainty evidence and no moderate- or high-certainty evidence of undesirable effects. Who receives care and when: queuing strategies and antenatal care to groups of mothers. Who provides care: lay health workers for caring for people with hypertension, lay health workers to deliver care for mothers and children or infectious diseases, lay health workers to deliver community-based neonatal care packages, midlevel health professionals for abortion care, social support to pregnant women at risk, midwife-led care for childbearing women, non-specialist providers in mental health and neurology, and physician-nurse substitution. Coordination of care: hospital clinical pathways, case management for people living with HIV and AIDS, interactive communication between primary care doctors and specialists, hospital discharge planning, adding a service to an existing service and integrating delivery models, referral from primary to secondary care, physician-led versus nurse-led triage in emergency departments, and team midwifery. Where care is provided: high-volume institutions, home-based care (with or without multidisciplinary team) for people living with HIV and AIDS, home-based management of malaria, home care for children with acute physical conditions, community-based interventions for childhood diarrhoea and pneumonia, out-of-facility HIV and reproductive health services for youth, and decentralised HIV care. Information and communication technology: mobile phone messaging for patients with long-term illnesses, mobile phone messaging reminders for attendance at healthcare appointments, mobile phone messaging to promote adherence to antiretroviral therapy, women carrying their own case notes in pregnancy, interventions to improve childhood vaccination. Quality and safety systems: decision support with clinical information systems for people living with HIV/AIDS. Complex interventions (cutting across delivery categories and other health system arrangements): emergency obstetric referral interventions.

AUTHORS' CONCLUSIONS

A wide range of strategies have been evaluated for improving delivery arrangements in low-income countries, using sound systematic review methods in both Cochrane and non-Cochrane reviews. These reviews have assessed a range of outcomes. Most of the available evidence focuses on who provides care, where care is provided and coordination of care. For all the main categories of delivery arrangements, we identified gaps in primary research related to uncertainty about the applicability of the evidence to low-income countries, low- or very low-certainty evidence or a lack of studies.

Implementation strategies for health systems in low-income countries: an overview of systematic reviews

BACKGROUND

A key function of health systems is implementing interventions to improve health, but coverage of essential health interventions remains low in low-income countries. Implementing interventions can be challenging, particularly if it entails complex changes in clinical routines; in collaborative patterns among different healthcare providers and disciplines; in the behaviour of providers, patients or other stakeholders; or in the organisation of care. Decision-makers may use a range of strategies to implement health interventions, and these choices should be based on evidence of the strategies' effectiveness.

OBJECTIVES

To provide an overview of the available evidence from up-to-date systematic reviews about the effects of implementation strategies for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on alternative implementation strategies and informing refinements of the framework for implementation strategies presented in the overview.

METHODS

We searched Health Systems Evidence in November 2010 and PDQ-Evidence up to December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of implementation strategies on professional practice and patient outcomes and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the review findings. Two overview authors independently screened reviews, extracted data and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence) and assessments of the relevance of findings to low-income countries.

MAIN RESULTS

We identified 7272 systematic reviews and included 39 of them in this overview. An additional four reviews provided supplementary information. Of the 39 reviews, 32 had only minor limitations and 7 had important methodological limitations. Most studies in the reviews were from high-income countries. There were no studies from low-income countries in eight reviews.Implementation strategies addressed in the reviews were grouped into four categories - strategies targeting:1. healthcare organisations (e.g. strategies to change organisational culture; 1 review);2. healthcare workers by type of intervention (e.g. printed educational materials; 14 reviews);3. healthcare workers to address a specific problem (e.g. unnecessary antibiotic prescription; 9 reviews);4. healthcare recipients (e.g. medication adherence; 15 reviews).Overall, we found the following interventions to have desirable effects on at least one outcome with moderate- or high-certainty evidence and no moderate- or high-certainty evidence of undesirable effects.1.Strategies targeted at healthcare workers: educational meetings, nutrition training of health workers, educational outreach, practice facilitation, local opinion leaders, audit and feedback, and tailored interventions.2.Strategies targeted at healthcare workers for specific types of problems: training healthcare workers to be more patient-centred in clinical consultations, use of birth kits, strategies such as clinician education and patient education to reduce antibiotic prescribing in ambulatory care settings, and in-service neonatal emergency care training.3. Strategies targeted at healthcare recipients: mass media interventions to increase uptake of HIV testing; intensive self-management and adherence, intensive disease management programmes to improve health literacy; behavioural interventions and mobile phone text messages for adherence to antiretroviral therapy; a one time incentive to start or continue tuberculosis prophylaxis; default reminders for patients being treated for active tuberculosis; use of sectioned polythene bags for adherence to malaria medication; community-based health education, and reminders and recall strategies to increase vaccination uptake; interventions to increase uptake of cervical screening (invitations, education, counselling, access to health promotion nurse and intensive recruitment); health insurance information and application support.

AUTHORS' CONCLUSIONS

Reliable systematic reviews have evaluated a wide range of strategies for implementing evidence-based interventions in low-income countries. Most of the available evidence is focused on strategies targeted at healthcare workers and healthcare recipients and relates to process-based outcomes. Evidence of the effects of strategies targeting healthcare organisations is scarce.
