Trends in task shifting in HIV treatment in Africa: Effectiveness, challenges and acceptability to the health professions

Task shifting for maternal and neonatal care in low-resource settings: A mixed-methods evaluation of a midwifery training program in rural Papua New Guinea

In an effort to reduce maternal and neonatal mortality, a rural health system in Papua New Guinea implemented a two-week midwifery training program for 47 nurses and community health workers. We evaluated this program by administering pre- and post-training knowledge tests, focus group discussions, a clinical vignette task, and key informant interviews. Participants improved significantly in their midwifery knowledge and demonstrated effective care in the clinical vignettes. Participants described the training as novel and beneficial. Program leaders were motivated to scale up the program and assess community-level impact. This program has strong potential to improve local obstetric care capacity.

A concept analysis: Support for lay healthcare workers in HIV services, Bojanala District, North West

BACKGROUND

 Different lay healthcare workers play an important role in the retention of clients to human immunodeficiency virus (HIV) care. Retention to HIV care is crucial to promote treatment continuation, viral suppression and reduced risk of transmission. However, lay healthcare workers view and perceive support differently.

OBJECTIVES

 The aim of the study was to investigate perceptions of healthcare workers regarding support provided to lay healthcare workers in HIV services. This article is a report of a concept analysis of healthcare workers' support provided to lay healthcare workers in HIV services, that was collected during the study. A concept analysis was done to explore the support attributes, clarify meaning and to understand its use within the lay healthcare workers' context in Bojanala District, situated in the North West province of South Africa.

METHOD

 The initial phase was data collection from lay healthcare workers, their supervisors and clients on antiretroviral therapy. Thereafter, the eight concept analysis steps of Walker and Avant were followed. Peer-reviewed articles on the support concept were searched and guided by data saturation.

RESULTS

 Responsiveness, provision, reciprocity and integration are key characteristics of support.

CONCLUSION

 Despite support being an interpersonal process, it is perceived subjectively. Support is necessary to continuously promote growth or endurance during adverse times.Contribution: The concept analysis will provide common understanding of support and information that is responsive to the needs of different lay healthcare workers.

Understanding the Role of Staff Nurses in Hypertension Management in Primary Care Facilities in India: A Time-Motion Study

INTRODUCTION

India is facing a shortage of staff nurses; thus, a better understanding of nurses' workloads is essential for improving and implementing noncommunicable disease (NCD) control strategies. We estimated the proportion of time spent by staff nurses on hypertension and other NCD activities in primary care facilities in 2 states in India.

METHODS

We conducted a cross-sectional study in 6 purposively selected primary care facilities in Punjab and Madhya Pradesh during July through September 2021. We used a standardized stopwatch to collect data for time spent on direct hypertension activities (measuring blood pressure, counseling, recording blood pressure measurement, and other NCD-related activities), indirect hypertension activities (data management, patient follow-up calls), and non-NCD activities. We used the Mann-Whitney U test to compare the median time spent on activities between facilities using paper-based records and the Simple mobile device-based app (open-source software).

RESULTS

Six staff nurses were observed for 213 person-hours. Nurses spent 111 person-hours (52%; 95% CI, 45%-59%) on direct hypertension activities and 30 person-hours (14%; 95% CI, 10%-19%) on indirect hypertension activities. The time spent on blood pressure measurement (34 minutes) and documentation (35 minutes) was the maximum time on any given day. Facilities that used paper records spent more median time (39 [IQR, 26-62] minutes) for indirect hypertension activities than those using the Simple app (15 [IQR, 11-19] minutes; P < .001).

CONCLUSION

Our study found that hypertension activities required more than half of nurses' time in India's primary care facilities. Digital systems can help to reduce the time spent on indirect hypertension activities.

Knowledge and Perceptions of Healthcare Workers about the Implementation of the Universal Test and Treat Guideline in Under-Resourced, High-HIV Prevalence Rural Settings

Background: South Africa (SA) began implementing its Universal Test and Treat (UTT) policy in September 2016 and Same Day Initiation (SDI) in 2017, aiming to meet the UNAIDS 90-90-90 targets by 2020. With significant advances in HIV testing, large gaps remain in the linkage and retention in care. As part of a contribution to the successful implementation of UTT, this study aims to examine progress in the implementation of the UTT and to identify gaps and facilitators in the successful implementation of the guidelines from the perspective of healthcare providers from under-resourced, high-HIV prevalence rural settings. Methods: We conducted a census of all 170 professional nurses from 18 primary healthcare (PHC) clinics in Rustenburg, South Africa, between October 2018 and February 2019. The perceptions, knowledge and attitudes of nursing staff associated with UTT implementation were investigated though the dissemination of self-administered questionnaires. Stata 16.0 was used to analyse the data. Frequency and contingency tables were used to present categorical data. The precision of the estimates was measured using a 95% confidence interval (95% CI), and the p-value of statistical significance is p < 0.05. Results: The facilities were found to have adequate governance and supervision, but gaps were identified, including staffing challenges, bottlenecks and under-resourced service delivery platforms. It was found that a high level of knowledge is a predictor of positive perception of the UTT programme and its implementation. Being supported by capacity development and having positive perceptions of UTT were important motivators for UTT implementation. Conclusions: This study was able to identify potential facilitators of the UTT strategy implementation at the selected facilities. Clinical guidelines and policies on UTT contributed to successful implementation, which means that the process of closing the gaps identified should prioritise the delivery, support and prioritisation of capacity development, infrastructure and the provision of clinical guidelines to all healthcare workers. It is recommended that nurses receive training on UTT and its benefits to increase their knowledge and promote its successful implementation in clinics.

Enabling mental health task-sharing: a collective case study of undergraduate clinical associate training programmes in South Africa

BACKGROUND

There is a shortage of the human resources needed to deliver mental health services which is likely to be exacerbated by COVID-19. Due to mental health workforce shortages, task-shifting and task-sharing approaches have been implemented in a number of countries. Clinical associates, a mid-level cadre working under the supervision of medical practitioners, could play a role in delivering mental health services but it is not clear if they are adequately prepared. This study explored the mental health curriculum content of the undergraduate clinical associate training programmes in South Africa and the views of key informants of the adequacy of training in mental health.

METHODS

A qualitative collective case study approach was utilised for this multisite study at the three universities in South Africa offering clinical associate degrees. The study consisted of in-depth interviews utilising videoconferencing of individuals involved in each programme and a document review. Thematic analysis of the data was conducted.

RESULTS

Nineteen interviews were conducted. Mental health formed part of the curriculum in all three programmes with the bulk of the training taking place in the final year of the three-year degree. Facility-based training ranged from two weeks to four weeks with one university only using hospitals with mental health units while two universities used hospitals at which the students were based for the year regardless of potential mental health exposure they would receive. The list of curricula inclusions extended to seldom-seen conditions. The quality of training and supervision appeared site-dependant and only one university set minimum experiential targets.

CONCLUSION

There is a basis on which to build the competencies and skills regarding mental health in this cadre. A training model that integrates mental health early in the undergraduate curriculum, focuses on common conditions and those with high disease burden, includes time in a mental health unit, provides facility-based trainers with detailed guidance to improve standardisation, and includes specific experiential targets that are monitored will enhance the potential utility of this cadre.

Risk factors for late linkage to care and delayed antiretroviral therapy initiation amongst HIV infected adults in sub-Saharan Africa: a systematic review and meta-analyses

BACKGROUND

Late treatment initiation threatens the clinical and public health benefits of antiretroviral therapy (ART). Quantitative synthesises of the existing evidence related to this is lacking in sub-Saharan Africa (SSA), which would help ascertain the best evidence-based interventions. This review aimed to systematically synthesise the available literature on factors affecting linkage to care and ART initiation amongst HIV-infected adults in SSA.

METHODS

Systematic searches were undertaken on four databases to identify observational studies investigating factors affecting both HIV care outcomes amongst adults (age ≥19 years) in SSA, and were published between January 1, 2015 and June 1, 2021. RevMan-5 software was used to conduct meta-analyses and Mantel-Haenszel statistics to pool outcomes with 95% confidence interval and <0.05 level of significance.

RESULTS

Forty-six studies were included in the systematic review, of which 18 fulfilled requirements for meta-analysis. In both narrative review and meta-analyses, factors related to health care delivery, individual perception and sociodemographic circumstances were associated with late linkage to care and delays in ART initiation.

CONCLUSION

This review identified a range of risk factors for late linkage to care and delayed ART initiation amongst HIV-infected adults in SSA. We recommend implementation of patient-centred intervention approaches to alleviate these barriers.

Training, Supervision, and Competence Assessment of Cameroonian Health Care Providers Using HPV Self-Sampling, Triage by Visual Inspection, and Treatment by Thermal Ablation in a Single Visit

Background

Developing human resource capacity and efficient deployment of skilled personnel are essential for cervical cancer screening program implementation in resource-limited countries. Our aim was to provide a context-specific training framework, supervision, and effectiveness evaluation of health care providers in a cervical cancer screening program.

Methods

A 5-year cervical cancer screening program was implemented in Dschang, West Cameroon. Women were invited to perform human papillomavirus self-sampling (Self-HPV), followed by triage using visual inspection with acetic acid (VIA) and thermal ablation if needed. Health care providers were trained in four key learning phases to perform counseling, screening, and treatment process in a single visit. Training included (i) a 3-day basic course, (ii) 3-day advanced practical training, (iii) 2 weeks of supervision, and (iv) bi-monthly supervision by a mentor. The diagnostic performance of health care providers was compared between two time periods, period I (September 2018 to April 2019) and period II (May 2019 to January 2020), for an overall 17-month study period.

Results

Fourteen health care providers were recruited for the training course and 12 of them completed the training objectives. Follow-up and evaluations were conducted for three health care providers working in the screening unit at Dschang District Hospital. During the study period, 1,609 women performed Self-HPV, among which 759 were screened during period I and 850 during period II. HPV positivity was 18.2 and 17.1%, and VIA positivity was 45.7 and 71.0% in period I and II, respectively. VIA sensitivity was 60.0% (95% confidence interval [CI] 26.2–87.8) and 80.8% (95% CI 60.6–93.4) in period I and II, respectively (p = 0.390). VIA specificity decreased between period I (57.4, 95% CI 48.1–66.3) and II (30.8, 95% CI 22.6–40.0) (p < 0.001). Health care providers demonstrated substantial agreement with their mentor in their diagnoses during both periods (period I: Cohen's kappa coefficient [k] = 0.73, 95% CI 0.62–0.85, and period II: k = 0.62 0.47–0.76; p = 0.0549).

Discussion

Training, supervision, and a focus on effectiveness in cervical cancer screening are interventions that contribute to improving frontline provider competencies and maintaining a high quality of health care service delivery.

A one-stop shop model for improved efficiency of pre-exposure prophylaxis delivery in public clinics in western Kenya: a mixed methods implementation science study

INTRODUCTION

In public clinics in Kenya, separate, sequential delivery of the component services of pre-exposure prophylaxis (PrEP) (e.g. HIV testing, counselling, and dispensing) creates long wait times that hinder clients' ability and desire to access and continue PrEP. We conducted a mixed methods study in four public clinics in western Kenya to identify strategies for operationalizing a one-stop shop (OSS) model and evaluate whether this model could improve client wait time and care acceptability among clients and providers without negatively impacting uptake or continuation.

METHODS

From January 2020 through November 2020, we collected and analysed 47 time-and-motion observations using Mann-Whitney U tests, 29 provider and client interviews, 68 technical assistance reports, and clinic flow maps from intervention clinics. We used controlled interrupted time series (cITS) to compare trends in PrEP initiation and on-time returns from a 12-month pre-intervention period (January-December 2019) to an 8-month post-period (January-November 2020, excluding a 3-month COVID-19 wash-out period) at intervention and control clinics.

RESULTS

From the pre- to post-period, median client wait time at intervention clinics dropped significantly from 31 to 6 minutes (p = 0.02), while median provider contact time remained around 23 minutes (p = 0.4). Intervention clinics achieved efficiency gains by moving PrEP delivery to lower volume departments, moving steps closer together (e.g. relocating supplies; cross-training and task-shifting), and differentiating clients based on the subset of services needed. Clients and providers found the OSS model highly acceptable and additionally identified increased privacy, reduced stigma, and higher quality client-provider interactions as benefits of the model. From the pre- to post-period, average monthly initiations at intervention and control clinics increased by 6 and 2.3, respectively, and percent of expected follow-up visits occurring on time decreased by 18% and 26%, respectively; cITS analysis of PrEP initiations (n = 1227) and follow-up visits (n = 2696) revealed no significant difference between intervention and control clinics in terms of trends in PrEP initiation and on-time returns (all p>0.05).

CONCLUSIONS

An OSS model significantly improved client wait time and care acceptability without negatively impacting initiations or continuations, thus highlighting opportunities to improve the efficiency of PrEP delivery efficiency and client-centredness.

Healthworker preparedness for COVID-19 management and implementation experiences: a mixed methods study in Uganda's refugee-hosting districts

Background

The negative impact of COVID-19 on population health outcomes raises critical questions on health system preparedness and resilience, especially in resource-limited settings. This study examined healthworker preparedness for COVID-19 management and implementation experiences in Uganda’s refugee-hosting districts.

Methods

A cross sectional, mixed-method descriptive study in 17 health facilities in 7 districts from 4 major regions. Total sample size was 485 including > 370 health care workers (HCWs). HCW knowledge, attitude and practices (KAP) was assessed by using a pre-validated questionnaire. The quantitative data was processed and analysed using SPSS 26, and statistical significance assumed at p < 0.05 for all statistical tests. Bloom's cutoff of 80% was used to determine threshold for sufficient knowledge level and practices with scores classified as high (80.0–100.0%), average (60.0–79.0%) and low (≤ 59.0%). HCW implementation experiences and key stakeholder opinions were further explored qualitatively using interviews which were audio-recorded, coded and thematically analysed.

Results

On average 71% of HCWs were knowledgeable on the various aspects of COVID-19, although there is a wide variation in knowledge. Awareness of symptoms ranked highest among 95% (p value < 0.0001) of HCWs while awareness of the criteria for intubation for COVID-19 patients ranked lowest with only 35% (p value < 0.0001). Variations were noted on falsehoods about COVID-19 causes, prevention and treatment across Central (p value < 0.0356) and West Nile (p value < 0.0161) regions. Protective practices include adequate ventilation, virtual meetings and HCW training. Deficient practices were around psychosocial and lifestyle support, remote working and contingency plans for HCW safety. The work environment has immensely changed with increased demands on the amount of work, skills and variation in nature of work. HCWs reported moderate control over their work environment but with a high level of support from supervisors (88%) and colleagues (93%).

Conclusions

HCWs preparedness is inadequate in some aspects. Implementation of healthcare interventions is constrained by the complexity of Uganda’s health system design, top-down approach of the national response to COVID-19 and longstanding health system bottlenecks. We recommend continuous information sharing on COVID-19, a design review with capacity strengthening at all health facility levels and investing in community-facing strategies.

Research priorities for accelerating the achievement of three 95 HIV goals in Cameroon: a consensus statement from the Cameroon HIV Research Forum (CAM-HERO)

INTRODUCTION

the Treat-All remains the globally endorsed approach to attain the 95-95-95 targets and end the AIDS pandemic by 2030, but requires some country-level contextualization. In Cameroon, the specific research agenda to inform strategies for improving HIV policy was yet to be defined.

METHODS

under the patronage of the Cameroon Ministry of health, researchers, policy makers, implementing partners, and clinicians from 13 institutions, used the Delphi method to arrive at a consensus of HIV research priorities. The process had five steps: 1) independent literature scan by 5 working groups; 2) review of the initial priority list; 3) appraisal of priorities list in a larger group; 4) refinement and consolidation by a consensus group; 5) rating of top research priorities.

RESULTS

five research priorities and corresponding research approaches, resulted from the process. These include: 1) effectiveness, safety and active toxicity monitoring of new and old antiretrovirals; 2) outcomes of Antiretroviral Therapy (ART) with focus in children and adolescents; 3) impact of HIV and ART on aging and major chronic diseases; 4) ART dispensation models and impact on adherence and retention; 5) evaluations of HIV treatment and prevention programs.

CONCLUSION

the research priorities resulted from a consensus amongst a multidisciplinary team and were based on current data about the pandemic and science to prevent, treat, and ultimately cure HIV. These priorities highlighted critical areas of investigation with potential relevance for the country, funders, and regulatory bodies.

Use of lay vaccinators in animal vaccination programmes: A scoping review

Background

The human resource gap in veterinary sectors, particularly in low-income countries, imposes limitations on the delivery of animal healthcare in hard-to-reach populations. Lay animal health workers have been deployed in these settings to fill the gap though there are mixed views about the benefits of doing this and whether they can deliver services safely. We mapped evidence on the nature and extent of roles assigned to lay animal vaccinators, and identified lessons useful for their future deployment.

Methodology/Principal findings

Following the PRISMA Extension for Scoping Reviews guidelines, we searched seven bibliographic databases for articles published between 1980 and 2021, with the search terms lay OR community-based OR volunteer AND "animal health worker" OR vaccinator*, and applied an a priori exclusion criteria to select studies. From 30 identified studies, lay vaccinators were used by non-government developmental (n = 12, 40%), research (n = 10, 33%) and government (n = 5, 17%) programmes to vaccinate domestic animals. The main reason for using lay vaccinators was to provide access to animal vaccination in the absence of professional veterinarians (n = 12, 40%). Reported positive outcomes of programmes included increased flock and herd sizes and farmer knowledge of best practice (n = 13, 43%); decreased disease transmission, outbreaks and mortality (n = 11, 37%); higher vaccination coverage (10, 33%); non-inferior seroconversion and birth rates among vaccinated herds (n = 3, 10%). The most frequently reported facilitating factor of lay vaccinator programmes was community participation (n = 14, 47%), whilst opposition from professional veterinarians (n = 8, 27%), stakeholders seeking financial gains to detriment of programmes goals (n = 8, 27%) and programming issues (n = 8, 27%) were the most frequently reported barriers. No study reported on cost-effectiveness and we found no record from a low and middle-income country of lay vaccinator programmes being integrated into national veterinary services.

Conclusion

Although the majority of included studies reported more benefits and positive perceptions of lay vaccinator programmes than problems and challenges, regularization will ensure the programmes can be designed and implemented to meet the needs of all stakeholders.

In the absence of professional animal healthcare workers in hard-to-reach settings, lay persons, with limited, non-formal training, have been used to provide animal healthcare services, including vaccination. In spite of the perceived crucial roles lay persons play in the animal health sector, their services are largely unrecognized within official animal healthcare systems. We compiled evidence on how lay persons have been used in animal vaccination programmes and make recommendations regarding how they can be used in more effective ways. We found they were used by both government and non-government institutions to vaccinate different domestic animals and provide regular animal healthcare services. They were mainly used where professional animal healthcare workers are not available or are limited in number. The programmes were more successful where they had the support of the public and institutions, and their outcomes were largely similar to those delivered by professionals. We also found that community participation was an important facilitating factor, whilst the main challenges they faced were opposition from professional veterinarians, financial interests of stakeholders and planning issues. We concluded that lay animal vaccinator programmes could be more beneficial if better regulated.

A nurse-led intervention to improve management of virological failure in public sector HIV clinics in Durban, South Africa: A pre- and post-implementation evaluation

BACKGROUND

Identification of patients on antiretroviral therapy (ART) with virological failure (VF) and the response in the public health sector remain significant challenges. We previously reported improvement in routine viral load (VL) monitoring after ART commencement through a health system-strengthening, nurse-led 'VL champion' programme as part of a multidisciplinary team in three public sector clinics in Durban, South Africa.

OBJECTIVES

To report on the impact of the VL champion model adapted to identify, support and co-ordinate the management of individuals with VF on first-line ART in a setting with limited electronic-based record capacity.

METHODS

We evaluated the VL champion model using a controlled before-after study design. A paper-based tool, the 'high VL register', was piloted under the supervision of the VL champion to improve data management, monitoring of counselling support, and enacting of clinical decisions. We abstracted chart and electronic data (TIER.net) for eligible individuals with VF in the year before and after implementation of the programme, and compared outcomes for individuals during these periods. Our primary outcome was successful completion of the VF pathway, defined as a repeat VL &lt;1 000 copies/mL or a change to second-line ART within 6 months of VF. In a secondary analysis, we assessed the completion of each step in the pathway.

RESULTS

We identified 60 and 56 individuals in the pre-intervention and post-intervention periods, respectively, with VF who met the inclusion criteria. Sociodemographic and clinical characteristics were similar between the periods. Repeat VL testing was completed in 61.7% and 57.8% of individuals in these two groups, respectively. We found no difference in the proportion achieving our primary outcome in the pre- and post-intervention periods: 11/60 (18.3%; 95% confidence interval (CI) 9 - 28) and 15/56 (22.8%; 95% CI 15 - 38), respectively (p=0.28). In multivariable logistic regression models adjusted for potential confounding factors, individuals in the post-intervention period had a non-significant doubling of the odds of achieving the primary outcome (adjusted odds ratio 2.07; 95% CI 0.75 - 5.72). However, there was no difference in the rates of completion of each step along the first-line VF cascade of care.

CONCLUSIONS

This enhanced intervention to improve VF in the public sector using a paper-based data management system failed to achieve significant improvements in first-line VF management over the standard of care. In addition to interventions that better address patient-centred factors that contribute to VF, we believe that there are substantial limitations to and staffing requirements involved in the ongoing utilisation of a paper-based tool. A prioritisation is needed to further expand and upgrade the electronic medical record system with capabilities for prompting staff regarding patients with missed visits and critical laboratory results demonstrating VF.

Feasibility of establishing a rehabilitation programme in a Vietnamese intensive care unit

Increasing numbers of people are surviving critical illness throughout the world, but survivorship is associated with long-term disability. In high-income settings physical rehabilitation is commonly employed to counter this and improve outcomes. These utilize highly-trained multidisciplinary teams and are unavailable and unaffordable in most low and middle income countries (LMICs). We aimed to design a sustainable intensive care unit (ICU) rehabilitation program and to evaluate its feasibility in a LMIC setting. In this project patients, care-givers and experts co-designed an innovative rehabilitation programme that can be delivered by non-expert ICU staff and family care-givers in a LMIC. We implemented this programme in adult patient with patients with tetanus at the Hospital for Tropical Diseases, Ho Chi Minh City over a 5-month period, evaluating the programme's acceptability, enablers and barriers. A 6-phase programme was designed, supported by written and video material. The programme was piloted in total of 30 patients. Rehabilitation was commenced a median 14 (inter quartile range (IQR) 10-18) days after admission. Each patient received a median of 25.5 (IQR 22.8-34.8) rehabilitation sessions out of a median 27 (22.8-35) intended (prescribed) sessions. There were no associated adverse events. Patients and staff found rehabilitation to be beneficial, enhanced relationships between carers, patients and staff and was deemed to be a positive step towards recovery and return to work. The main barrier was staff time. The programme was feasible for patients with tetanus and viewed positively by staff and participants. Staff time was identified as the major barrier to ongoing implementation.

Optimizing Differentiated HIV Treatment Models in Urban Zimbabwe: Assessing Patient Preferences Using a Discrete Choice Experiment

Differentiated service delivery holds great promise for streamlining the delivery of health services for HIV. This study used a discrete choice experiment to assess preferences for differentiated HIV treatment delivery model characteristics among 500 virally suppressed adults on antiretroviral therapy in Harare, Zimbabwe. Treatment model characteristics included location, consultation type, healthcare worker cadre, operation times, visit frequency and duration, and cost. A mixed effects logit model was used for parameter estimates to identify potential preference heterogeneity among participants, and interaction effects were estimated for sex and age as potential sources of divergence in preferences. Results indicated that participants preferred health facility-based services, less frequent visits, individual consultations, shorter waiting times, lower cost and, delivered by respectful and understanding healthcare workers. Some preference heterogeneity was found, particularly for location of service delivery and group vs. individual models; however, this was not fully explained by sex and age characteristics of participants. In urban areas, facility-based models, such as the Fast Track model requiring less frequent clinic visits, are likely to better align with patient preferences than some of the other community-based or group models that have been implemented. As Zimbabwe scales up differentiated treatment models for stable patients, a clear understanding of patient preferences can help in designing services that will ensure optimal utilization and improve the efficiency of service delivery.

Interest in Communication Technology by Rural Caregivers of Adolescents with Mental Health Issues in South Africa: The Mmogo-Method®

Caregivers determine the level of care adolescents with mental issues receive; however, caregivers' own needs are often unmet. Communication technology can be tailored to address these challenges, especially in a rural environment. This study aimed to explore caregivers' interest in using communication technology to provide support to address challenges. This study involved a visual-based narrative inquiry that gathered data through the Mmogo-method^®. Three (n = 3) groups were held with rural caregivers (n = 17) of adolescents with mental health issues in a rural area in the Free State province of South Africa during 2017. Three themes captured challenges confronting caregivers, namely, psychosocial, social resources, and informational challenges. Interest in communication technology was captured in a fourth theme. The findings indicate that communication technology can address caregivers' challenges by providing support and information to caregivers in rural areas. Communication technology, including mobile phones, electronic devices, and the Internet, has transformed healthcare services and proved to be valuable in resource constraint environments.

Universal HIV testing and treatment and HIV stigma reduction: a comparative thematic analysis of qualitative data from the HPTN 071 (PopART) trial in South Africa and Zambia

Despite continued development of effective HIV treatment, expanded access to care and advances in prevention modalities, HIV-related stigma persists. We examine how, in the context of a universal HIV-testing and treatment trial in South Africa and Zambia, increased availability of HIV services influenced conceptualisations of HIV. Using qualitative data, we explore people's stigma-related experiences of living in 'intervention' and 'control' study communities. We conducted exploratory data analysis from a qualitative cohort of 150 households in 13 study communities, collected between 2016 and 2018. We found that increased availability of HIV-testing services influenced conceptualisations of HIV as normative (non-exceptional) and the visibility of people living with HIV (PLHIV) in household and community spaces impacted opportunities for stigma. There was a shift in community narratives towards individual responsibility to take up (assumingly) widely available service - for PLHIV to take care of their own health and to prevent onward transmission. Based on empirical data, we show that, despite a growing acceptance of HIV-related testing services, anticipated stigma persists through the mechanism of shifting responsibilisation. To mitigate the responsibilisation of PLHIV, heath implementers need to adapt anti-stigma messaging and especially focus on anticipated stigma.

The association between HIV tri-therapy with the development of Type-2 Diabetes Mellitus in a rural South African District: A case-control study

BACKGROUND

Combination antiretroviral drugs (cARVs) prolong patients' lives but are unfortunately thought to increase complications related to metabolic disorders including type-2 Diabetes Mellitus (DM). We sought to confirm the association of cARVs with type-2 DM and ascertain the extent of this association in a rural South African setting.

METHODS

A case-control study of 177 (33.33%) cases with HIV/AIDS and type-2 DM were selected and compared with 354 (66.67%) non-DM HIV/AIDS unmatched controls from a rural district of South Africa's third most populous province (Eastern Cape). Cases were identified from community health centres using the district health information system, and controls were identified using simple random sampling from the same health facilities. Odds Ratios (OR), together with 95% confidence intervals, were calculated for all the univariable and multivariable logistic analyses.

RESULTS

This study found that cARVs significantly increased the occurrence of type-2 DM among HIV patients. Patients on protease inhibitors (PIs) were at least 21 times significantly (p<0.0001) more likely to be diabetic than those on the fixed dose combination (FDC); those on stavudine (D4T) and zidovudine (AZT) were 2.45 times and 9.44 times respectively more likely to be diabetic than those on FDC (p<0.05). The odds of diabetes increased by more than three-folds for those who had been on antiretroviral drugs for more than 6 years (p<0.005).

CONCLUSION

This study has been able to establish the association between cARVs and type-2 DM. It therefore proposes consideration of the usage of AZT, D4T, lopivavir and ritonavir for the treatment of HIV. The study further proposes more prospective research to test these findings further.

Task-shifting directly observed treatment and multidrug-resistant tuberculosis injection administration to lay health workers: stakeholder perceptions in rural Eswatini

BACKGROUND

Eswatini is facing a critical shortage of human resources for health (HRH) and limited access to multidrug-resistant tuberculosis (MDR-TB) treatment in rural areas. This study assessed multiple stakeholders' perceptions of task-shifting directly observed treatment (DOT) supervision and administration of intramuscular MDR-TB injections to lay health workers (LHWs).

METHODS

A mixed methods study comprising a cross-sectional survey using a semi-structured questionnaire with community treatment supporters (CTSs) and a focus group discussion with key stakeholders including representatives from the Eswatini Ministry of Health (MOH), donor organisations, professional regulatory institutions, nursing academia, civil society and healthcare providers was conducted in May 2017. Descriptive statistics, thematic content analysis and data triangulation aided in the interpretation of results.

RESULTS

A large majority of CTSs (n = 78; 95.1%) were female and 33 (40.2%) were older than 50 years. Most (n = 7; 70.0%) key stakeholders had over 10 years of work experience in policy-making, advocacy in the fields of HRH or day-to-day practice in MDR-TB management. Task-shifting of MDR-TB injection administration was implemented without national policy guidance and regulation. Stakeholders viewed the strategy to be driven by the prevailing shortage of professional frontline HRH and limited access to MDR-TB treatment. Task-shifting was perceived to improve medication adherence, and reduce stigma and transport-related MDR-TB treatment access barriers. Frontline healthcare workers and implementing donor partners fully supported task-shifting. Policy-makers and other stakeholders accepted task-shifting conditionally due to fears of poor standards of care related to perceived incompetence of CTSs. Appropriate compensation, adequate training and supervision, and non-financial incentives were suggested to retain CTSs. A holistic task-shifting policy and collaboration between the MOH, academia and nursing council in regulating the practice were recommended.

CONCLUSIONS

Stakeholders generally accepted the delegation of DOT supervision and administration of intramuscular MDR-TB injections to LHWs as a strategy to increase access to treatment, albeit with some apprehension. Findings from this study stress that task-shifting is not a panacea for HRH shortages, but a short-term solution that must form part of an overall simultaneous strategy to train, attract and retain adequate numbers of professional healthcare workers in Eswatini. To address some of the apprehension and ambivalence about expanding access to MDR-TB services through task-shifting, attention should be paid to important aspects such as competence-based training, certification and accreditation, adequate supportive on-the-job supervision, recognition, compensation, and expediting policy and regulatory support for LHWs.

Nurse- and Midwife-Led HIV Services in Eastern and Southern Africa: Challenges and Opportunities for Health Facilities

In eastern and southern Africa, much is unknown about implementation of nurse-initiated and managed antiretroviral therapy (NIMART). The purpose of this study was to identify perceived barriers and facilitators of NIMART for the prevention of mother-to-child transmission and pediatric HIV services in high-volume, high HIV-burden health facilities across this region. A total of 211 nurses, midwives, and nurse midwives and 62 supervisors from 30 health facilities in 11 countries participated in this mixed-methods evaluation. The findings show that although nurses, midwives, and nurse midwives clearly had the authority to provide NIMART services, they did not necessarily feel that they were well prepared and supported to do so. Deficits in supportive supervision and clinical mentorship were viewed as substantial challenges to effective provision of NIMART for the prevention of mother-to-child transmission and pediatric HIV services-particularly with respect to pediatric HIV services. Health facilities have important opportunities to advance NIMART practice through strengthening these aspects of in-service support.

Clinical outcomes after first-line HIV treatment failure in South Africa: the next cascade of care

Introduction

There is limited literature on the appropriateness of viral load (VL) monitoring and management of detectable VL in public health settings in rural South Africa.

Methods

We analysed data captured in the electronic patient register from HIV‐positive patients ≥ 15 years old initiating antiretroviral therapy (ART) in 17 public sector clinics in rural KwaZulu‐Natal, during 2010–2016. We estimated the completion rate for VL monitoring at 6, 12, and 24 months. We described the cascade of care for those with any VL measurement ≥ 1000 HIV‐1 RNA copies/mL after ≥ 20 weeks on ART, including the following proportions: (1) repeat VL within 6 months; (2) re‐suppressed; (3) switched to second‐line regimen.

Results

There were 29 384 individuals who initiated ART during the period [69% female, median age 31 years (interquartile range 25–39)]. Of those in care at 6, 12, and 24 months, 40.7% (9861/24 199), 34% (7765/22 807), and 25.5% (4334/16 965) had a VL test at each recommended time‐point, respectively. The VL results were documented at all recommended time‐points for 12% (2730/22 807) and 6.2% (1054/16 965) of ART‐treated patients for 12 and 24 months, respectively. Only 391 (18.3%) of 2135 individuals with VL ≥ 1000 copies/mL on first‐line ART had a repeat VL documenting re‐suppression or were appropriately changed to second‐line with persistent failure. Completion of the treatment failure cascade occurred a median of 338 days after failure was detected.

Conclusion

We found suboptimal VL monitoring and poor responses to virologic failure in public‐sector ART clinics in rural South Arica. Implications include increased likelihood of morbidity and transmission of drug‐resistant HIV.

An Electronic-Based Curriculum to Train Acute Care Providers in Rural Haiti and India

BACKGROUND

Access to a trained, competent health care workforce remains a challenge globally, particularly in rural settings. To bridge this gap, the World Health Organization calls for innovations in electronic learning and task shifting. Yet, these approaches are underutilized due to cost, challenges associated with implementing technology, and a lack of suitably educated trainees.

OBJECTIVE

We explored the feasibility of the Acute Care Providers Project (ACPP) to remotely train community members to be health care providers in 2 sites: Haiti and India.

METHODS

The ACP program is an asynchronous curriculum that provides core health content and a structured approach to clinical care through an electronic curriculum. The curriculum is reinforced with case-based practice and hands-on workshops for procedural skills. ACPP was deployed in rural Haiti and India. Evaluation of the program included multiple-choice pretests and posttests, an objective structured clinical examination (OSCE), and direct observation of skills.

RESULTS

Four Haitian and 55 Indian trainees completed the course. In Haiti, mean scores were 34.8% (SD 12.4) on the pretest and 78.0% (SD 6.5) on the posttest (P = .004). Trainees scored 100% on the OSCE and passed the skills checklist. In India, mean scores were 16.5% (SD 3.9) on the pretest and 81.7% (SD 9.0) on the posttest (P < .001). Trainees scored a median of 91.8% (SD 3.95) on the OSCE and all passed the skills checklist.

CONCLUSIONS

The ACPP offers a scalable, replicable asynchronous curriculum to train lay individuals to provide basic health care in rural communities.

Feasibility of engaging caregivers in at-home surveillance of children with uncomplicated severe acute malnutrition

Many factors can contribute to low coverage of treatment for severe acute malnutrition (SAM), and a limited number of health facilities and trained personnel can constrain the number of children that receive treatment. Alternative models of care that shift the responsibility for routine clinical and anthropometric surveillance from the health facility to the household could reduce the burden of care associated with frequent facility-based visits for both healthcare providers and caregivers. To assess the feasibility of shifting clinical surveillance to caregivers in the outpatient management of SAM, we conducted a pilot study to assess caregivers' understanding and retention of key concepts related to the surveillance of clinical danger signs and anthropometric measurement over a 28-day period. At the time of a child's admission to nutritional treatment, a study nurse provided a short training to groups of caregivers on two topics: (a) clinical danger signs in children with SAM that warrant facility-based care and (b) methods to measure and monitor their child's mid-upper arm circumference. Caregiver understanding was assessed using standardized questionnaires before training, immediately after training, and 28 days after training. Knowledge of most clinical danger signs (e.g., convulsions, edema, poor appetite, respiratory distress, and lethargy) was low (0-45%) before training but increased immediately after and was retained 28 days after training. Agreement between nurse-caregiver mid-upper arm circumference colour classifications was 77% (98/128) immediately after training and 80% after 28 days. These findings lend preliminary support to pursue further study of alternative models of care that allow for greater engagement of caregivers in the clinical and anthropometric surveillance of children with SAM.

Missed nursing care in newborn units: a cross-sectional direct observational study

BACKGROUND

Improved hospital care is needed to reduce newborn mortality in low/middle-income countries (LMIC). Nurses are essential to the delivery of safe and effective care, but nurse shortages and high patient workloads may result in missed care. We aimed to examine nursing care delivered to sick newborns and identify missed care using direct observational methods.

METHODS

A cross-sectional study using direct-observational methods for 216 newborns admitted in six health facilities in Nairobi, Kenya, was used to determine which tasks were completed. We report the frequency of tasks done and develop a nursing care index (NCI), an unweighted summary score of nursing tasks done for each baby, to explore how task completion is related to organisational and newborn characteristics.

RESULTS

Nursing tasks most commonly completed were handing over between shifts (97%), checking and where necessary changing diapers (96%). Tasks with lowest completion rates included nursing review of newborns (38%) and assessment of babies on phototherapy (15%). Overall the mean NCI was 60% (95% CI 58% to 62%), at least 80% of tasks were completed for only 14% of babies. Private sector facilities had a median ratio of babies to nurses of 3, with a maximum of 7 babies per nurse. In the public sector, the median ratio was 19 babies and a maximum exceeding 25 babies per nurse. In exploratory multivariable analyses, ratios of ≥12 babies per nurse were associated with a 24-point reduction in the mean NCI compared with ratios of ≤3 babies per nurse.

CONCLUSION

A significant proportion of nursing care is missed with potentially serious effects on patient safety and outcomes in this LMIC setting. Given that nurses caring for fewer babies on average performed more of the expected tasks, addressing nursing is key to ensuring delivery of essential aspects of care as part of improving quality and safety.

Strengthening and Expanding Child Services in Low Resource Communities: The Role of Task-Shifting and Just-in-Time Training

In the United States, the demand for child mental health services is increasing, while the supply is limited by workforce shortages. These shortages are unlikely to be corrected without significant structural changes in how mental health services are provided. One strategy for bridging this gap is task-shifting, defined as a process by which services that are typically delivered by professionals are moved to individuals with less extensive qualifications or training. Although task-shifting can increase the size of the workforce, there are challenges related to training new workers. In this paper, we propose Just-In-Time Training (JITT) as one strategy for improving task-shifting efforts. We define JITT as on-demand training experiences that only include what is necessary, when it is necessary, to promote competent service delivery. We offer a proof of concept from our own work shifting counseling and academic support tasks from school mental health professionals to pre-baccalaureate mentors, citing lessons learned during our iterative process of JITT development. We conclude with a series of key considerations for scaling up the pairing of task-shifting and JITT, including expanding the science of JITT and anticipating how task-shifting and JITT would work within the context of dynamic mental health service systems.

[Human Resources for health policy mapping in Francophone African countries.]

OBJECTIVE

To identify all training, recruitment, deployment and retention programmes for healthcare human resources in five Francophone African countries in order to analyse progress in the authorities' efforts to resolve the problems of human resources for health.

METHODS

Analysis of policy processes was based on the University of Wisconsin logical framework approach to identify and describe programmes detailing missions and objectives, and outcome indicators. Data were derived from document analysis and interviews with key resource persons (N = 69).

RESULTS

Four main processes were identified: (1) training policies; (2) recruitment interventions; (3) strategies to improve governance by the creation of professional boards; (4) interventions on financial and non-financial incentive mechanisms. Two main groups of countries can be distinguished. One group presents a coherent succession of strategy integration (Burkina Faso, Mali) focusing on training policies to gradually move towards recruitment policies, deployment and incentive mechanisms. The other group presents a rupture of this political process with a return to training policies (Chad, Côte d'Ivoire) and recruitment and deployment policies (Côte d'Ivoire).

CONCLUSION

This study highlights the absence of structural reforms to improve health care performance to achieve Universal Health Coverage. A lack of policy impact evaluation and evidence-based data was also observed.

Innovative Models in Mental Health Delivery Systems: Task Sharing Care with Non-specialist Providers to Close the Mental Health Treatment Gap

PURPOSE OF REVIEW

Most people do not have access to adequate mental health care, and lack of skilled human resources is a major factor. We provide a narrative review of approaches to implementing task sharing-engaging non-specialist providers-to deliver mental health care.

RECENT FINDINGS

There is strong evidence both for the effectiveness of task sharing as a means of delivering care for a range of conditions across settings and for the effectiveness of non-specialist providers and health workers in delivering elements of culturally adapted psychosocial and psychological interventions for common and severe mental disorders. Key approaches to facilitate task sharing of care include balanced care, collaborative care, sustained training and supervision, use of trans-diagnostic interventions based on a dimensional approach to wellness and illness, and the use of emerging digital technologies. Non-specialist providers and health workers are well positioned to deliver evidence-based interventions for mental disorders, and a variety of delivery approaches can support, facilitate, and sustain this innovation. These approaches should be used, and evaluated, to increase access to mental health services.

Task-shifting for cardiovascular risk factor management: lessons from the Global Alliance for Chronic Diseases

Task-shifting to non-physician health workers (NPHWs) has been an effective model for managing infectious diseases and improving maternal and child health. There is inadequate evidence to show the effectiveness of NPHWs to manage cardiovascular diseases (CVDs). In 2012, the Global Alliance for Chronic Diseases funded eight studies which focused on task-shifting to NPHWs for the management of hypertension. We report the lessons learnt from the field. From each of the studies, we obtained information on the types of tasks shifted, the professional level from which the task was shifted, the training provided and the challenges faced. Additionally, we collected more granular data on ‘lessons learnt ’ throughout the implementation process and ‘design to implementation’ changes that emerged in each project. The tasks shifted to NPHWs included screening of individuals, referral to physicians for diagnosis and management, patient education for lifestyle improvement, follow-up and reminders for medication adherence and appointments. In four studies, tasks were shifted from physicians to NPHWs and in four studies tasks were shared between two different levels of NPHWs. Training programmes ranged between 3 and 7 days with regular refresher training. Two studies used clinical decision support tools and mobile health components. Challenges faced included system level barriers such as inability to prescribe medicines, varying skill sets of NPHWs, high workload and staff turnover. With the acute shortage of the health workforce in low-income and middle-income countries (LMICs), achieving better health outcomes for the prevention and control of CVD is a major challenge. Task-shifting or sharing provides a practical model for the management of CVD in LMICs.

"Life continues": Patient, health care and community care workers perspectives on self-administered treatment for rifampicin-resistant tuberculosis in Khayelitsha, South Africa

Background

Self-administered treatment (SAT), a differentiated model of care for rifampicin-resistant tuberculosis (RR-TB), might address adherence challenges faced by patients and health care systems. This study explored patient, health-care worker (HCW) and community care worker (CCW) perspectives on a SAT pilot programme in South Africa, in which patients were given medication to take at home with the optional support of a CCW.

Methods

We conducted a mixed-methods study from July 2016-June 2017. The quantitative component included semi-structured questionnaires with patients, HCWs and CCWs; the qualitative component involved in-depth interviews with patients enrolled in the pilot programme. Interviews were conducted in isiXhosa, translated, transcribed and manually coded.

Results

Overall, 27 patients, 12 HCWs and 44 CCWs were enrolled in the quantitative component; nine patients were also interviewed. Of the 27 patients who completed semi-structured questionnaires, 22 were HIV-infected and 17 received a monthly supply of RR TB treatment. Most HCWs and CCWs (10 and 32, respectively) understood the pilot programme; approximately half (n = 14) of the patients could not correctly describe the pilot programme. Overall, 11 and 41 HCWs and CCWs reported that the pilot programme promoted treatment adherence. Additionally, 11 HCWs reported that the pilot programme relieved pressure on the clinic. Key qualitative findings highlighted the importance of a support person and how the flexibility of SAT enabled integration of treatment into their daily routines and reduced time spent in clinics. The pilot programme was also perceived to allow patients more autonomy and made it easier for them to manage side-effects.

Conclusion

The SAT pilot programme was acceptable from the perspective of patients, HCWs and CCWs and should be considered as a differentiated model of care for RR-TB, particularly in settings with high burdens of HIV, in order to ease management of treatment for patients and health-care providers.

Couples' voluntary HIV counseling and testing provider training evaluation, Zambia

With the expansion of couples' voluntary HIV counseling and testing (CVCT) in urban Zambia, there is a growing need to evaluate CVCT provider trainings to ensure that couples are receiving quality counseling and care. We evaluated provider knowledge scores, pre- and post-training and predictors of pre- and post-training test scores. Providers operating in 67 government clinics in four Copperbelt Province cities were trained from 2008 to 2013 in three domains: counseling, rapid HIV laboratory testing and data management. Trainees received pre- and post-training tests on domain-specific topics. Pre- and post-training test scores were tabulated by provider demographics and training type, and paired t-tests evaluated differences in pre- and post-training test scores. Multivariable ANCOVA determined predictors of pre- and post-training test scores. We trained 1226 providers, and average test scores increased from 68.8% pre-training to 83.8% post-training (p < 0.001). Test scores increased significantly for every demographic group and training type (p < 0.001) with one exception-test scores did not significantly increase for those receiving counseling or data management training who had less than a high school education. In multivariable analysis, higher educational level and having a medical background were predictive of a higher pre-test score; higher pre-test scores and having a medical background were predictive of higher post-test scores. Pre- and post-test assessments are critical to ensure quality services, particularly as task-shifting from medical to lay staff becomes more common. Assessments showed that our CVCT trainings are successful at increasing knowledge, and that those with lower education may benefit from repeat trainings.

Pathways of care for HIV infected children in Beira, Mozambique: pre-post intervention study to assess impact of task shifting

Background

In 2013, Mozambique implemented task-shifting (TS) from clinical officers to maternal and child nurses to improve care for HIV positive children < 5 years old. A retrospective, pre-post intervention study was designed to evaluate effectiveness of a new pathway of care in a sample of Beira District Local Health Facilities (LHFs), the primary, local, community healthcare services.

Methods

The study was conducted by accessing registries of At Risk Children Clinics (ARCCs) and HIV Health Services. Two time periods, pre- and post-intervention, were compared using a set of endpoints. Variables distribution was explored using descriptive statistics. T-student, Mann Whitney and Chi-square tests were used for comparisons.

Results

Overall, 588 HIV infected children (F = 51.4%) were recruited, 330 belonging to the post intervention period. The mean time from referral to ARCC until initiation of ART decreased from 2.3 (± 4.4) to 1.1 (± 5.0) months after the intervention implementation (p-value: 0.000). A significant increase of Isoniazid prophylaxis (O.R.: 2.69; 95%CI: 1.7–4.15) and a decrease of both regular nutritional assessment (O.R. = 0.45; 95%CI: 0.31–0.64) and CD4 count at the beginning of ART (O.R. = 0.46; 95%CI: 0.32–0.65) were documented after the intervention.

Conclusions

Despite several limitations and controversial results on nutrition assessment and CD4 count at the initiation of ART reported after the intervention, it could be assumed that TS alone may play a role in the improvement of the global effectiveness of care for HIV infected children only if integrated into a wider range of public health measures.

The impact of HIV prevalence, conflict, corruption, and GDP/capita on treatment cascades: data from 137 countries

OBJECTIVE

In 2014, UNAIDS and partners set the 90-90-90 targets for the HIV treatment cascade. Multiple social, political and structural factors might influence progress towards these targets. We assessed how close countries and regions are to reaching these targets, and compared cascade outcomes with HIV prevalence, gross domestic product (GDP)/capita, conflict and corruption.

METHODS

Country-level HIV cascade data on diagnosis, ART coverage and viral suppression, from 2010 to 2016 were extracted from national reports, published papers and the www.AIDSinfoOnline database, and analysed. Weighted least-squares regression was used to assess predictors of cascade achievement: region, HIV prevalence, GDP/capita, the 2016 Corruption Perceptions Index (CPI), which is an international ranking system, and the 2016 Global Peace Index (GPI), which ranks all countries based on three main categories: societal safety, militarisation and conflict.

RESULTS

Data were available for diagnosis for 84 countries, ART coverage for 137 countries, and viral suppression for 94 countries. Regions with the lowest ART coverage were South-east Asia and Pacific (36%), Eastern Europe and Central Asia (17%), and Middle East and North Africa (13%). Lower HIV prevalence was associated with poorer cascade results. Countries with higher GDP/capita achieved higher ART coverage (P<0.001). Furthermore, countries with lower levels of peace and higher corruption had lower ART coverage (P<0.001). Countries with a GPI >2.5 all had ART coverage of <40%.

CONCLUSION

Only one country has reached the UNAIDS 90-90-90 targets. International comparison remains difficult due to heterogeneous data reporting. Difficulty meeting UNAIDS targets is associated with lower GDP/capita, lower HIV prevalence, higher corruption and conflict levels.

Towards 90-90-90 Target: Factors Influencing Availability, Access, and Utilization of HIV Services-A Qualitative Study in 19 Ugandan Districts

Background

UNAIDS has set a new target 90-90-90 by 2020. To achieve this target, current programs need to address challenges that limit access, availability, and utilization of HIV testing and treatment services. Therefore, the aim of this study was to identify the barriers that influence access, availability, and utilization of HIV services in rural Uganda within the setting of a large donor funded program.

Methods

We conducted key informant interviews with stakeholders at the district level, staff of existing HIV/AIDS projects, and health facilities in 19 districts. Data were also collected from focus group discussions comprised of clients presenting for HIV care and treatment. Data were transcribed and analyzed using content analysis. Results. Barriers identified were as follows: (1) drug shortages including antiretroviral drugs at health facilities. Some patients were afraid to start ART because of worrying about shortages; (2) distance and (3) staffing shortages; (4) stigma persistence; (5) lack of social and economic support initiatives that enhance retention in treatment.

Conclusions

In conclusion, our study has identified several factors that influence access, availability, and utilization of HIV services. Programs need to address drug and staff shortages, HIV stigma, and long distances to health facilities to broaden access and utilization in order to realize the UNAIDS target.

Training And Supervision Did Not Meaningfully Improve Quality Of Care For Pregnant Women Or Sick Children In Sub-Saharan Africa

In-service training courses and supportive supervision of health workers are among the most common interventions to improve the quality of health care in low- and middle-income countries. Despite extensive investment from donors, evaluations of the long-term effect of these two interventions are scarce. We used nationally representative surveys of health systems in seven countries in sub-Saharan Africa to examine the association of in-service training and supervision with provider quality in antenatal and sick child care. The results of our analysis showed that observed quality of care was poor, with fewer than half of evidence-based actions completed by health workers, on average. In-service training and supervision were associated with quality of sick child care; they were associated with quality of antenatal care only when provided jointly. All associations were modest-at most, improvements related to interventions were equivalent to 2 additional provider actions out of the 18-40 actions expected per visit. In-service training and supportive supervision as delivered were not sufficient to meaningfully improve the quality of care in these countries. Greater attention to the quality of health professional education and national health system performance will be required to provide the standard of health care that patients deserve.

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.

Assessing home-based rehabilitation within the development of an integrated model of care for people living with HIV in a resource-poor community

Background

People living with HIV (PLHIV) are living longer lives but are at a greater risk of developing disability. South Africa has the largest antiretroviral therapy (ART) programme in the world, shifting HIV from a deadly to a chronic disease. The integration of rehabilitation into chronic care is therefore now crucial to ensure the highest quality of life of PLHIV.

Aim

To describe how a home-based rehabilitation (HBR) programme adhered to the fundamental principles of a theoretical model of integrated care developed for the study setting in KwaZulu-Natal, South Africa.

Method

The process and results from the HBR programme were assessed in relation to the model of care to ascertain which principles of the model were addressed with the HBR programme and which elements require further investigation.

Results

The HBR programme was able to apply a number of principles such as evidence-based practice, task shifting to lay personnel, enabling patient-centred care and maximising function and independence of PLHIV. Other elements such as the adoption of a multidisciplinary approach, training on the use of disability screening tools and the use of evidence to influence policy development were more difficult to implement.

Conclusion

It is possible to implement elements of the integrated model of care. Further research is needed to understand how principles that require further training and collaboration with other stakeholders can be implemented. The results of this study provide additional evidence towards understanding the feasibility of the theoretical model and what is required to adjust and test the full model.

Mother Infant Retention for Health (MIR4Health): Study Design, Adaptations, and Challenges With PMTCT Implementation Science Research

Background:

Effective retention of HIV-infected mothers and their infants is fraught with multiple challenges, resulting in loss across the continuum of prevention of mother-to-child HIV transmission (PMTCT) care and missed opportunities to offer life-saving HIV prevention and treatment.

Methods:

The Mother Infant Retention for Health study is an individual-randomized study evaluating the effectiveness of active patient follow-up compared with standard of care on the combined outcome of attrition of HIV-infected women and their infants at 6 months postpartum. Lay counselors administered the active patient follow-up package of interventions, including individualized health education, use of flip charts during clinic visits, and at home, phone and short message service appointment reminders, active phone and physical tracking of patients immediately after missed clinic visits, and individualized retention and adherence support.

Results:

Use of study visits to indicate participant progression along the PMTCT cascade highlights the nature of loss among women and infants in PMTCT care because of issues such as pregnancy complications, infant deaths, and transfer out. Delay in implementation of Option B+, unanticipated slow enrollment, a health-care worker strike, rapid HIV test kit shortages, and changes in national PMTCT guidelines necessitated several modifications to the protocol design and implementation to ensure successful completion of the study.

Conclusions:

Flexibility when operationalizing an implementation science study is critical in the context of the shifting landscape in a noncontrolled “real-world” setting.

Trial Registration:

Clinicaltrials.gov NCT01962220.

Mapping evidence of interventions and strategies to bridge the gap in the implementation of the prevention of mother-to-child transmission of HIV programme policy in sub-Saharan countries: A scoping review

BACKGROUND

Prevention of mother-to-child transmission (PMTCT) of HIV is a life-saving public health intervention. Sub-Saharan African (SSA) countries have made significant progress in the programme, but little is known about the strategies used by them to eliminate mother-to-child transmission of HIV.

AIM

To map evidence of strategies and interventions employed by SSA in bridging the implementation gap in the rapidly changing PMTCT of HIV programme policy.

METHODS

Electronic search of the databases MEDLINE, PubMed and SABINET for articles published in English between 2001 and August 2016. Key words included 'Sub-Saharan African countries', 'implementation strategies', 'interventions to bridge implementation gap', 'prevention of mother-to-child transmission of HIV' and 'closing implementation gap'.

RESULTS

Of a total of 743 articles, 25 articles that met the inclusion criteria were included in the study. Manual content analysis resulted in the identification of three categories of strategies: (1) health system (referral systems, integration of services, supportive leadership, systematic quality-improvement approaches that vigorously monitors programme performance); (2) health service delivery (task shifting, networking, shared platform for learning, local capacity building, supportive supervision); as well as (3) community-level strategies (community health workers, technology use - mHealth, family-centred approaches, male involvement, culturally appropriate interventions).

CONCLUSION

There are strategies that exist in SSA countries. Future research should examine multifaceted scientific models to prioritise the highest impact and be evaluated for effectiveness and efficiency.

Effectiveness of Alcohol, Smoking, and Substance Involvement Screening Test-Linked Brief Intervention on Harmful and Hazardous Alcohol Use in Nigerian Semirural Communities: A Non-Randomized Intervention Study

OBJECTIVE

To determine the prevalence of alcohol consumption and the effectiveness of the alcohol, smoking, and substance involvement screening test (ASSIST)-linked brief intervention on hazardous and harmful alcohol use in semirural settings in Nigeria.

METHODS

In this single arm non-randomized intervention study delivered by community health extension workers (CHEW), participants (N = 1,203), 15 years and older, recruited between October 2010 and April 2011 were assessed for prevalence of alcohol consumption and the associated level of risk. Scores of 0-10 were classified as lower risk scores, 11-26 as moderate risk, and 27+ as high risk. This was followed by a brief intervention. Prevalence of alcohol consumption and level of risk was assessed at 3 and 6 months postbrief intervention. Main outcome measure was the change in ASSIST scores at 3 and 6 months postintervention.

RESULTS

There was a statistically significant difference in the prevalence of alcohol use at baseline compared with that at 6 months, χ²(2) = 4.2, p = 0.01. Among all respondents, a repeated measures ANOVA with a Greenhouse-Geisser correction showed that mean ASSIST score significantly reduced between time points [F(1.541, 34.092) = 53.241, p < 0.001]. Post hoc tests using the Bonferroni correction revealed that this difference was due to a significant reduction in the mean ASSIST scores at 3 months vs. baseline, p = 0.001, but not at 3 vs. 6 months, p = 0.09.

CONCLUSION

There is a potential for CHEW-administered ASSIST-linked screening, brief intervention, and referral to treatment for unhealthy alcohol use in Nigerian semirural communities. This is feasible considering serious dearth of addiction specialists in the country.

Human resources for health strategies adopted by providers in resource-limited settings to sustain long-term delivery of ART: a mixed-methods study from Uganda

BACKGROUND

Human resources for health (HRH) constraints are a major barrier to the sustainability of antiretroviral therapy (ART) scale-up programs in Sub-Saharan Africa. Many prior approaches to HRH constraints have taken a top-down trend of generalized global strategies and policy guidelines. The objective of the study was to examine the human resources for health strategies adopted by front-line providers in Uganda to sustain ART delivery beyond the initial ART scale-up phase between 2004 and 2009.

METHODS

A two-phase mixed-methods approach was adopted. In the first phase, a survey of a nationally representative sample of health facilities (n = 195) across Uganda was conducted. The second phase involved in-depth interviews (n = 36) with ART clinic managers and staff of 6 of the 195 health facilities purposively selected from the first study phase. Quantitative data was analysed based on descriptive statistics, and qualitative data was analysed by coding and thematic analysis.

RESULTS

The identified strategies were categorized into five themes: (1) providing monetary and non-monetary incentives to health workers on busy ART clinic days; (2) workload reduction through spacing ART clinic appointments; (3) adopting training workshops in ART management as a motivation strategy for health workers; (4) adopting non-physician-centred staffing models; and (5) devising ART program leadership styles that enhanced health worker commitment.

CONCLUSIONS

Facility-level strategies for responding to HRH constraints are feasible and can contribute to efforts to increase country ownership of HIV programs in resource-limited settings. Consideration of the human resources for health strategies identified in the study by ART program planners and managers could enhance the long-term sustainment of ART programs by providers in resource-limited settings.

Can the UNAIDS 90-90-90 target be achieved? A systematic analysis of national HIV treatment cascades

Background

In 2014, the Joint United Nations Programme on HIV and AIDS (UNAIDS) and partners set the ‘90-90-90 targets’; aiming to diagnose 90% of all HIV positive people, provide antiretroviral therapy (ART) for 90% of those diagnosed and achieve viral suppression for 90% of those treated, by 2020. This results in 81% of all HIV positive people on treatment and 73% of all HIV positive people achieving viral suppression. We aimed to analyse how effective national HIV treatment programmes are at meeting these targets, using HIV care continuums or cascades.

Methods

We searched for HIV treatment cascades for 196 countries in published papers, conference presentations, UNAIDS databases and national reports. Cascades were constructed using reliable, generalisable, recent data from national, cross-sectional and longitudinal study cohorts. Data were collected for four stages; total HIV positive people, diagnosed, on treatment and virally suppressed. The cascades were categorised as complete (four stages) or partial (3 stages), and analysed for ‘break points’ defined as a drop >10% in coverage between consecutive 90-90-90 targets.

Results

69 country cascades were analysed (32 complete, 37 partial). Diagnosis (target one—90%) ranged from 87% (the Netherlands) to 11% (Yemen). Treatment coverage (target two—81% on ART) ranged from 71% (Switzerland) to 3% (Afghanistan). Viral suppression (target three—73% virally suppressed) was between 68% (Switzerland) and 7% (China).

Conclusions

No country analysed met the 90-90-90 targets. Diagnosis was the greatest break point globally, but the most frequent key break point for individual countries was providing ART to those diagnosed. Large disparities were identified between countries. Without commitment to standardised reporting methodologies, international comparisons are complex.
