Does task shifting yield cost savings and improve efficiency for health systems? A systematic review of evidence from low-income and middle-income countries

Successful task shifting: a mixed-methods cross-sectional evaluation of an emergency obstetric care program to increase access to cesarean sections in rural Nepal

BACKGROUND

Direct obstetric causes of maternal mortality account for approximately 86% of all global maternal deaths. In Nepal, 12% of all deaths of women of reproductive age are due to preventable obstetric complications in significant part due to the limited distribution and skill level of human resources.

OBJECTIVES

To address this, the Advanced Skilled Birth Attendant (ASBA) task-shifting initiative was developed to train medical officers to perform Cesarean sections (CSs) and manage obstetric emergencies in Nepal. Until now, there has been limited study of the program's efficacy.

METHODS

A survey targeting all 234 ASBA graduates resulted in 93 usable surveys for multivariate regression. Additionally, seven rural government hospitals with ASBA graduates were selected for 13 in-depth interviews and 6 focus group discussions. Results were then triangulated.

RESULTS

Immediately after training, 92.7% of ASBA graduates reported performing CSs, with the majority (65.6%) continuing to perform CSs today. Of the ASBAs not performing CSs, 51.7% could be explained by the lack of a functional operating theater, despite being at hospitals expected to provide CSs. ASBAs were significantly more likely to be performing CSs with a family physician or another ASBA present (p < 0.001; p < 0.001). Their work was perceived to increase the use of services, improve access, reduce out-referrals, and reduce the burden of CSs on any one staff member.

CONCLUSIONS

The ASBA program successfully reduces human resource shortages, expands the provision of life-saving Cesarean section, and improves the working conditions in rural hospitals within the LMIC setting.

Integrated Primary Healthcare Delivery of Hypertension and Diabetes Services: A Task Analysis of Nurses and Doctors in Rural Philippines

Objectives

This study aimed to describe the roles and responsibilities of doctors and nurses in managing conditions like hypertension and diabetes in rural areas.

Methods

This study employed a cross-sectional study design using the task analysis methodology. A self-administered questionnaire derived from a national health practice guideline was used. A combination of frequency, criticality, and performance was assessed to identify tasks that needed attention by educators and policymakers.

Results

Of the 142 health workers who participated in the study, 81% were nurses and 19% were doctors. The tasks most frequently performed by these professionals were taking vital signs (88.7%), recording patient history (87.3%), and advising patients on regular follow-ups (86.6%). In terms of criticality, the top three tasks were performing diagnostic tests for acute chest pain (50.8%), diagnosing neurological disorders (49.2%), and referring patients for specialized tests at other facilities (43.6%). However, the tasks perceived as most challenging or outside their capability were the Fagerstorm test for assessing nicotine dependence (57.5%), the AUDIT tool for identifying binge drinkers (55.5%), and fundoscopy for diagnosing diabetic retinopathy (54%).

Conclusion

The primary care practice of the participants typically involved tasks that are centered on health promotion or disease prevention. Many of the tasks are shared by doctors and nurses, with some highly critical tasks performed less frequently due to a lack of training. Pre-service courses may need to be revised to ensure that health professionals have the required skills to carry out shared tasks.

Integration of psychological interventions in multi-sectoral humanitarian programmes: a systematic review

BACKGROUND

Every year, millions of people are affected by humanitarian crises. With a growing population of people affected, the need for coordination and integration of services aiming to improve the effectiveness of mental health and psychosocial support also grows. In this study, we examine how psychological interventions in humanitarian settings globally have been implemented through integration into programming outside of formal healthcare delivery through multisectoral integration.

METHODS

A comprehensive search of six databases and reference checking was undertaken in 2022. We included studies focusing on implementation strategies and implementation outcomes of multi-sectoral, integrated psychological interventions, with no year limits. We extracted data using the software Covidence, and used the software to manage screening and reviewing processes. All studies were critically appraised for quality and rigor using the mixed-methods appraisal tool.

RESULTS

Eight studies were included in total. We found that interventions targeted conflict affected, displaced and disaster recovering populations. The interventions demonstrated moderate success in reducing psychological distress and enhancing disaster preparedness. We found that key implementation outcomes investigated and prioritised include acceptability, feasibility, and relevance. The studies reported on integration processes that involved task shifting primarily, with an emphasis on different formats of adaptation, partnership creation and capacity development to maximise effectiveness of integrated interventions.

CONCLUSION

Overall, there is little research being done to rigorously document the processes and experiences of integrating psychological interventions with non-health interventions. This could be an indication that, while multisectoral integration may be more common in practice, little research is being done or reported in this area formally. There is an urgent need for further research into integrated multi-sectoral interventions. This research should aim to understand how social, cultural, and environmental contexts in different ways, and to different degrees, affect what is acceptable and feasible to deliver and how these ultimately influence the impact of integrated interventions.

The longitudinal impact of an evidence-based multiple family group intervention (Amaka Amasanyufu) on family cohesion among children in Uganda: Analysis of the cluster randomized SMART Africa-Uganda scale-up study (2016-2022)

Family functioning plays a critical role in childhood disruptive behavior disorders (The Family Journal, 2003, 11(1), 33-41; Research in Nursing and Health, 2016, 39(4), 229-243). Yet, there is limited research on the impact of evidence-based family strengthening interventions on improving family cohesion as a protective factor among children experiencing behavioral challenges. To address this gap, we analyzed data (N = 636) from the SMART Africa-Uganda study (2016-2022), a cluster randomized clinical trial testing an evidence-based family-strengthening intervention called Amaka Amasanyufu (translated as "Happy Families" in the local language). Children aged 8-13 and their caregivers were recruited from 26 public primary schools that were randomized to: (1) control condition receiving generalized psychosocial literature (10 schools), (2) intervention delivered via parent peers (eight schools), and (3) intervention delivered via community healthcare workers (eight schools). Children completed the family cohesion questionnaire at baseline, 8 weeks, 16 weeks, and 6 months post-intervention completion. The intervention effectiveness was evaluated via a three-level logistic mixed effects model with pairwise comparisons across study conditions within each time point. Participants in the parent-peer intervention group had greater odds of being in the higher family cohesion group than participants in the control group at 8 weeks (OR = 3.24), 16 weeks (OR = 1.88) and 6 months (OR = 2.07). At 8 weeks, 16 weeks, and 6 months, participants in the community health worker group had 3.98, 2.08, and 1.79 times greater odds of being in the higher family cohesion group than participants in the control group, respectively. Our findings strengthen the evidence base for Amaka Amansayufu as an effective intervention that can be utilized in SSA to improve family cohesion in families with children experiencing behavioral challenges.

Midwives as trainers for a neonatal clinical decision support system at four rural health facilities in eastern Uganda: a mixed-methods observational study

OBJECTIVES

To evaluate acceptability and effectiveness of midwives as trainers for NoviGuide, a neonatal clinical decision support system (CDSS).

DESIGN

A 20-months, mixed-methods open cohort study.

SETTINGS AND PARTICIPANTS

Nurse-midwives at four rural health facilities in eastern Uganda.

METHODS

We developed a midwife-led trainer programme and instructed two midwives as NoviGuide Trainers in three 3-hour-long sessions. Trainers trained all nurse-midwives at each site in single 3-hour-long sessions. Using the Kirkpatrick model, we evaluated acceptability at level 1 for participant's reaction and level 3 for participant's attitudes towards the programme. We evaluated effectiveness at level 2 for newly learnt skills, and level 3 for participant's uptake of NoviGuide and perception of newborn care practices. We used surveys and focus groups at baseline, 3 months and 6 months and viewed usage data from September 2020 through May 2022.

RESULTS

All 49 participants were female, 23 (46.9%) owned smartphones, 12 (24.5%) accessed the internet daily and 17 (34.7%) were present by study end following staff changes. All participants perceived the use of midwives as NoviGuide Trainers to be an acceptable approach to introduce NoviGuide (mean 5.9 out of 6, SD 0.37). Participants reported gaining new skills and confidence to use NoviGuide; some, in turn, trained others. Participants reported improvement in newborn care. Uptake of NoviGuide was high. Of 49 trained participants, 48 (98%) used NoviGuide. A total of 4045 assessments of newborns were made. Of these, 13.8% (558/4045) were preterm, 17.5% (709/4045) weighed under 2.5 kg and 21.1% (855/4045) had a temperature <36.5°C.

CONCLUSION

This midwife-led programme was acceptable and led to self-reported improvement in newborn care and high uptake of NoviGuide among nurse-midwives. Task shifting CDSS expert roles to midwives could facilitate large-scale implementation. However, resources like internet coverage, reliable electricity and mobile devices should be considered in low-resource settings.

Enablers and barriers of community health programs for improved equity and universal coverage of primary health care services: A scoping review

BACKGROUND

Community health programs (CHPs) are integral components of primary health care (PHC) systems and support the delivery of primary care and allied health and nursing care services. CHPs are necessary platforms for delivering health services toward universal health coverage (UHC). There are limited prior studies on comprehensive evidence synthesis on how CHPs strengthen community health systems for the demand and supply of PHC services. Therefore, this scoping review synthesized existing evidence on the interlinkage between CHPs and the community health system and beyond for delivering and utilising PHC services toward UHC.

METHODS

We conducted a scoping review of research articles on CHPs. We identified research articles in six databases (PubMed/Medline, CINAHL, Scopus, Cochrane, Web of Science, and Embase) and Google Scholar using search terms under three concepts: CHPs, PHC, and UHC. Of the 3836 records identified, 1407 duplicates were removed, and 2346 were removed based on titles and abstracts. A total of 83 articles were eligible for the full-text review; of them, 18 articles were removed with reasons, and the other 16 were included through hand search. Themes were identified and explained using Sacks and colleagues' "Beyond the Building Block" framework.

RESULTS

A total of 81 studies were included in the final review. Studies described CHPs as foundations for community health system readiness for PHC services, including decentralization in the health sector, community-controlled governance, resource mobilization, ensuring health commodities (e.g., through community pharmacies), and information evidence. These foundational inputs mediate the actions of CHPs by partnership with community organizations and health workforces (e.g., community health workers). CHPs contributed to improved access to health services by providing health services in public health emergencies, affordable and comprehensive care, and modifying social determinants of health.

CONCLUSIONS

CHPs are platforms for implementing and delivering PHC services close to communities. They help to modify social determinants of health, promote health and wellbeing, reduce care costs, prevent disease progression, and reduce hospitalisation rates. CHPs are integral parts of community health systems and require investment to improve access to PHC services. Gaps and challenges of CHPs include inadequate funding, limited engagement of the private sector, poor quality of health services, and limited focus on non-communicable diseases (NCDs). Further implementation research is needed to mitigate the burden of NCDs. Health systems efforts focus on increasing resources (e.g., financial and human) required in CHPs to ensure the quality of PHC services provided through CHPs toward better service access, and reaching the unreached and achieve equity and universality of PHC services.

Opportunities and challenges in utilizing community assets to extend chronic care management in podoconiosis endemic areas: Evidence from Northwestern Ethiopia

Community-based chronic care intervention is important in the control and prevention of lifelong conditions such as podoconiosis and similar 'intensive disease management' neglected tropical diseases (NTDs). Despite a call for such interventions, few efforts have been made to identify opportunities and challenges related to their implementation. Employing a qualitative approach, this study explored the possibility of engaging community actors, physical places and networks to promote chronic care management in rural Ethiopia. We gathered data from affected individuals, community members, local leaders, health professionals and community health workers between April and May 2022. The study revealed that affected individuals, family members, religious leaders, traditional leaders, and health professionals have the potential to extend chronic care management in rural areas. Houses, churches, schools, and healthcare facilities are suitable venues at which to perform interventions. Strong community solidarity and political will are vital to chronic care interventions, while lack of understanding about chronic conditions, financial constraints, and limited resources at healthcare facilities could pose challenges. Using community assets has great promise for expanding chronic care management with minimal costs and efforts in under resourced areas. Achieving this will require a successful plan to coordinate the collaboration among the agents and settings.

Health services under pressure: a scoping review and development of a taxonomy of adaptive strategies

OBJECTIVE

The objective of this review was to develop a taxonomy of pressures experienced by health services and an accompanying taxonomy of strategies for adapting in response to these pressures. The taxonomies were developed from a review of observational studies directly assessing care delivered in a variety of clinical environments.

DESIGN

In the first phase, a scoping review of the relevant literature was conducted. In the second phase, pressures and strategies were systematically coded from the included papers, and categorised.

DATA SOURCES

Electronic databases (MEDLINE, Embase, CINAHL, PsycInfo and Scopus) and reference lists from recent reviews of the resilient healthcare literature.

ELIGIBILITY CRITERIA

Studies were included from the resilient healthcare literature, which used descriptive methodologies to directly assess a clinical environment. The studies were required to contain strategies for managing under pressure.

RESULTS

5402 potential articles were identified with 17 papers meeting the inclusion criteria. The principal source of pressure described in the studies was the demand for care exceeding capacity (ie, the resources available), which in turn led to difficult working conditions and problems with system functioning. Strategies for responding to pressures were categorised into anticipatory and on-the-day adaptations. Anticipatory strategies included strategies for increasing resources, controlling demand and plans for managing the workload (efficiency strategies, forward planning, monitoring and co-ordination strategies and staff support initiatives). On-the-day adaptations were categorised into: flexing the use of existing resources, prioritising demand and adapting ways of working (leadership, teamwork and communication strategies).

CONCLUSIONS

The review has culminated in an empirically based taxonomy of pressures and an accompanying taxonomy of strategies for adapting in response to these pressures. The taxonomies could help clinicians and managers to optimise how they respond to pressures and may be used as the basis for training programmes and future research evaluating the impact of different strategies.

The impacts of task shifting on the management and treatment of malnourished children in Northern Kenya: a cluster-randomized controlled trial

Treating children with acute malnutrition can be challenging, particularly regarding access to healthcare facilities during treatment. Task shifting, a strategy of transferring specific tasks to health workers with shorter training and fewer qualifications, is being considered as an effective approach to enhancing health outcomes in primary healthcare. This study aimed to assess the effectiveness of integrating the treatment of acute malnutrition by community health volunteers into integrated community case management in two sub-counties in northern Kenya (Loima and Isiolo). We conducted a two-arm non-inferiority cluster-randomized controlled trial across 20 community health units. Participants were children aged 6-59 months with uncomplicated acute malnutrition. In the intervention group, community health volunteers used simplified tools and protocols to identify and treat eligible children at home and provided the usual integrated community case management package. In the control group, community health volunteers provided the usual integrated community case management package only (screening and referral of the malnourished children to the health facilities). The primary outcome was recovery (MUAC ≥12.5 cm for 2 consecutive weeks). Results show that children in the intervention group were more likely to recover than those in the control group [73 vs 50; risk difference (RD) = 26% (95% CI 12 to 40) and risk ratio (RR) = 2 (95% CI 1.2 to 1.9)]. The probability of defaulting was lower in the intervention group than in the control group: RD = -21% (95% CI -31 to -10) and RR = 0.3 (95% CI 0.2 to 0.5). The intervention reduced the length of stay by about 13 days, although this was not statistically significant and varied substantially by sub-county. Integrating the treatment of acute malnutrition by community health volunteers into the integrated community case management programme led to better malnutrition treatment outcomes. There is a need to integrate acute malnutrition treatment into integrated community case management and review policies to allow community health volunteers to treat uncomplicated acute malnutrition.

Shifting roles of community health workers in the prevention and management of noncommunicable disease during the COVID-19 pandemic: a scoping review

Community Health Workers (CHWs) play a crucial role in the prevention and management of noncommunicable diseases (NCDs). The COVID-19 pandemic triggered the implementation of crisis-driven responses that involved shifts in the roles of CHWs in terms of delivering services for people with NCDs. Strategically aligning these shifts with health systems is crucial to improve NCD service delivery. The aim of this review was to identify and describe COVID-19-triggered shifting roles of CHWs that are promising in terms of NCD service delivery. We searched Ovid Medline, Embase, CINAHL, Web of Science and CABI for Global Health for relevant articles published between 1 January 2020 and 22 February 2022. Studies that were conducted within a COVID-19 context and focused on the shifted roles of CHWs in NCD service delivery were included. We used Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines to report the findings. A total of 25 articles from 14 countries were included in this review. We identified 12 shifted roles of CHWs in NCD service delivery during COVID-19, which can be categorized in three dimensions: 'enhanced' role of CHWs that includes additional tasks such as medication delivery; 'extended' roles such as the delivery of NCD services at household level and in remote communities; and 'enabled' roles through the use of digital health technologies. Health and digital literacy of people with NCDs, access to internet connectivity for people with NCDs, and the social and organizational context where CHWs work influenced the implementation of the shifted roles of CHWs. In conclusion, the roles of CHWs have shifted during the COVID-19 pandemic to include the delivery of additional NCD services at home and community levels, often supported by digital technologies. Given the importance of the shifting roles in the prevention and management of NCDs, adaptation and integration of these shifted roles into the routine activities of CHWs in the post-COVID period is recommended.

Applying a Primary Health Care Approach to Closing the Human Resource for Health Gaps for Immunization

This perspective is focused on the evidence on human resources for health (HRH) solutions for immunization, as a part of a primary health care (PHC) approach.. In the wake of the COVID-19 pandemic and 50 years since the Expanded Program on Immunization (EPI) clocks 50 years since its inception. was initiated, evidence and experience demonstrate the significant HRH gaps in many countries and globally, and how countries are seeking innovative ways of closing them with limited resources. The aim of this perspective article is to highlight the growing gap between the needs and the realities related to health workforce for PHC, including immunization, and to call for increasing the visibility of HRH within global and national immunization agendas. This perspective highlights key guidelines and tools to improve HRH, such as integrating immunization and primary health care, addressing the mental health needs of the health workforce, addressing gender-related issues, rationalizing the roles and composition of PHC workforce teams, and meeting the surge requirements related to health emergencies.

Adaptation and feasibility of WHO PM+ for adolescents living with HIV in KwaZulu-Natal Province, South Africa: an implementation feasibility study protocol

INTRODUCTION

Adolescents living with HIV (ALHIV) are an extremely vulnerable population, with the burden of mental health problems carefully documented together with the constraints for receiving timely and adequate management of the problems, especially in rural settings. Problem Management Plus (PM+) is a scalable psychological intervention for individuals impaired by distress in communities exposed to adversity. Initially developed for adult populations, few studies have assessed its potential to address adolescent distress. This study aims to co-adapt PM+ with an adherence component (PM+Adherence) for ALHIV and to evaluate its acceptability and feasibility in rural Kwa-Zulu Natal Province, South Africa.

METHODS AND ANALYSIS

We will use a mixed-methods approach over three phases. The first phase will include a realist synthesis and collection of formative data from up to 60 ALHIV, caregivers and healthcare providers to inform the adaptation of WHO PM+, including the components of an adherence module. During the second phase, we will undertake the cultural adaptation of the PM+Adherence intervention. The third phase will involve a hybrid type 3 implementation strategy among ALHIV aged 16-19 years (n=50) to implement and evaluate the feasibility of the culturally co-adapted PM+Adherence. The feasibility indicators to be evaluated include reach, adoption, attrition, implementation and acceptability of the adapted intervention, which will be assessed qualitatively and quantitatively. In addition, we will assess preliminary effectiveness using an intention-to-treat approach on HIV-related indicators and mental health outcomes at baseline, end intervention, 2-month follow-up during the 6-month implementation.

DISCUSSION

We expect that the PM+Adherence will be acceptable and can feasibly be delivered by lay counsellors in resource-limited rural KwaZulu-Natal.

ETHICS AND DISSEMINATION

Ethical clearance has been obtained from the University of KwaZulu-Natal Biomedical Research Ethics Committee, (BREC/00005743/2023). Dissemination plans include presentations at scientific conferences, peer-reviewed publications and community level.

Health Professions Education Strategies for Enhancing Capacity for Task-Shifting and Task-Sharing Implementation in Africa: A Scoping Review

INTRODUCTION

To compensate for the shortage of health workers and effectively use the available health workforce to provide access to health services at various levels of the health system, several countries are implementing task-shifting and task-sharing (TSTS). This scoping review was conducted to synthesize evidence on health professions education (HPE) strategies applied to enhance capacities for TSTS implementation in Africa.

METHODS

This scoping review was conducted using the enhanced Arksey and O'Malley's framework for scoping reviews. The sources of evidence included CINAHL, PubMed, and Scopus.

RESULTS

Thirty-eight studies conducted in 23 countries provided insights on the strategies implemented in various health services contexts including general health, cancer screenings, reproductive, maternal, newborn, child and adolescent health, HIV/AIDS, emergency care, hypertension, tuberculosis, eye care, diabetes, mental health, and medicines. The HPE strategies applied were in-service training, onsite clinical supervision and mentoring, periodic supportive supervision, provision of job aides, and preservice education.

DISCUSSION

Scaling up HPE based on the evidence from this study will contribute immensely to enhancing the capacity of health workers in contexts where TSTS are being implemented or planned to provide quality health services based on the population's health needs.

"Let him die. He caused it": A qualitative study on cancer stigma in Tanzania

Cancer stigma presents a critical barrier to care seeking, contributing to delayed presentation and poor cancer outcomes worldwide. The burden of cancer in Tanzania is on the rise, with cancer being the third-leading cause of death in the country. Despite rising incidence and poor outcomes of cancer, cancer-related stigma interventions have received low prioritization. There is a need for sound research that focuses on understanding attitudes driving stigma, its impact on care-seeking and treatment adherence, and intervention models to reduce stigma. We used a cross-sectional qualitative study design. We administered three open-ended qualitative questions to 140 adults newly diagnosed with cancer in Moshi, Tanzania. The questions explored common attitudes toward people with cancer, the perceived impact of cancer-related stigma on care engagement, and ideas for reducing cancer stigma. Patients were recruited during routine appointments at the Cancer Center at Kilimanjaro Christian Medical Center. Data were analyzed using a team-based, applied thematic approach and NVivo 12 software. All participants described stigma as a significant challenge for treatment and receiving support from their social networks. Perceptions of financial burden, misconceptions about cancer, such as the belief that it is contagious, and fear of death, were common attitudes driving cancer stigma. Most participants feared that symptoms would prevent them from being able to work and that the cost of cancer care would drive away loved ones. Stigma was not a ubiquitous response, as some participants reported increased care and social support from family members after a cancer diagnosis. Experiences of stigma contributed to feelings of shame, fear of burdening the family, reduced resources to access treatment, and disengagement from care. Common substitutes to medical therapies included religious interventions and traditional medicine, perceived as less expensive and less stigmatizing. Many participants felt they would benefit from improved financial support, professional counseling, and education for families and communities to reduce stigmatizing attitudes and enhance social support. There is a need for intervention studies focused on improving cancer literacy, community advocacy to reduce cancer stigma, and increasing emotional and practical support for people with cancer and their families. There is also a clear need for policy efforts to make cancer care more affordable and accessible to reduce the financial burden on patients and families.

Taking a trauma and adversity perspective to climate change mental health

The European Journal of Psychotraumatology has had a long interest in advancing the science around climate change and traumatic stress. In this special issue, we include papers that responded to a special call in this area. Six major themes emerge from these papers and together they contribute to trauma and adversity model of the mental health impacts of climate change. We argue that, in addition to individual vulnerability factors, we must consider the (i) cumulative trauma burden that is associated with exposure to ongoing climate change-related impacts; (ii) impact of both direct and indirect stressors; (iii) individual and community protective factors. These factors can then guide intervention models of recovery and ongoing resilience.

A scoping review of the literature on the application and usefulness of the Problem Management Plus (PM+) intervention around the world

BACKGROUND

Given the high rates of common mental disorders and limited resources, task-shifting psychosocial interventions are needed to provide adequate care. One such intervention developed by the World Health Organization is Problem Management Plus (PM+).

AIMS

This review maps the evidence regarding the extent of application and usefulness of the PM+ intervention, i.e. adaptability, feasibility, effectiveness and scalability, since it was introduced in 2016.

METHOD

We conducted a scoping review of seven literature databases and grey literature from January 2015 to February 2024, to identify peer-reviewed and grey literature on PM+ around the world.

RESULTS

Out of 6739 potential records, 42 met the inclusion criteria. About 60% of the included studies were from low- and middle-income countries. Findings from pilot/feasibility trials demonstrated that PM+ is feasible, acceptable and safe. Results from definitive randomised controlled trials at short-term follow-up also suggested that PM+ is effective, with overall moderate-to-large effect sizes, in improving symptoms of common mental health problems. Although PM+ was more effective in reducing symptoms of common mental disorders, it was found to be costlier compared to usual care in the only study that evaluated its cost-effectiveness.

CONCLUSIONS

Our findings indicate that PM+, in its individual and group formats, can be adapted and effectively delivered by trained helpers to target a wide range of common mental health concerns. More effectiveness and implementation evidence is required to understand the long-term impact of PM+, its cost-effectiveness and scalability, and moderators of treatment outcomes such as gender and delivery formats.

Rehabilitation delivery models to foster healthy ageing-a scoping review

Introduction

Rehabilitation is essential to foster healthy ageing. Older adults have unique rehabilitation needs due to a higher prevalence of non-communicable diseases, higher susceptibility to infectious diseases, injuries, and mental health conditions. However, there is limited understanding of how rehabilitation is delivered to older adults. To address this gap, we conducted a scoping review to describe rehabilitation delivery models used to optimise older adults' functioning/functional ability and foster healthy ageing.

Methods

We searched Medline and Embase (January 2015 to May 2022) for primary studies published in English describing approaches to provide rehabilitation to older adults. Three authors screened records for eligibility and extracted data independently and in duplicate. Data synthesis included descriptive quantitative analysis of study and rehabilitation provision characteristics, and qualitative analysis to identify rehabilitation delivery models.

Results

Out of 6,933 identified records, 585 articles were assessed for eligibility, and 283 studies with 69,257 participants were included. We identified six rehabilitation delivery models: outpatient (24%), telerehabilitation (22%), home (18.5%), community (16.3%), inpatient (14.6%), and eldercare (4.7%). These models often involved multidisciplinary teams (31.5%) and follow integrated care principles (30.4%). Most studies used a disease-centred approach (59.0%), while studies addressing multimorbidity (6.0%) and prevalent health problems of older adults, such as pain, low hearing, and vision, or incontinence were scarce. The most frequently provided interventions were therapeutic exercises (54.1%), self-management education (40.1%), and assessment of person-centred goals (40%). Other interventions, such as assistive technology (8.1%) and environmental adaptations (7.4%) were infrequent.

Conclusions

Focusing on primary studies, this scoping review provides an overview of rehabilitation delivery models that are used to foster healthy ageing and highlights research gaps that require further attention, including a lack of systematic assessment of functioning/functional ability, a predominance of disease-centred rehabilitation, and a scarcity of programmes addressing prevalent issues like pain, hearing/vision loss, fall prevention, incontinence, and sexual dysfunctions. Our research can facilitate evidence-based decision-making and inspire further research and innovation in rehabilitation and healthy ageing. Limitations of our study include reliance on published research to infer practice and not assessing model effectiveness. Future research in the field is needed to expand and validate our findings.

Hypertension care cascades and reducing inequities in cardiovascular disease in low- and middle-income countries

Improving hypertension control in low- and middle-income countries has uncertain implications across socioeconomic groups. In this study, we simulated improvements in the hypertension care cascade and evaluated the distributional benefits across wealth quintiles in 44 low- and middle-income countries using individual-level data from nationally representative, cross-sectional surveys. We raised diagnosis (diagnosis scenario) and treatment (treatment scenario) levels for all wealth quintiles to match the best-performing country quintile and estimated the change in 10-year cardiovascular disease (CVD) risk of individuals initiated on treatment. We observed greater health benefits among bottom wealth quintiles in middle-income countries and in countries with larger baseline disparities in hypertension management. Lower-middle-income countries would see the greatest absolute benefits among the bottom quintiles under the treatment scenario (29.1 CVD cases averted per 1,000 people living with hypertension in the bottom quintile (Q1) versus 17.2 in the top quintile (Q5)), and the proportion of total CVD cases averted would be largest among the lowest quintiles in upper-middle-income countries under both diagnosis (32.0% of averted cases in Q1 versus 11.9% in Q5) and treatment (29.7% of averted cases in Q1 versus 14.0% in Q5) scenarios. Targeted improvements in hypertension diagnosis and treatment could substantially reduce socioeconomic-based inequalities in CVD burden in low- and middle-income countries.

South Africa celebrates 15 years of clinical associates

ABSTRACT

Clinical associates (ClinAs) in South Africa are modeled after physician associates in the United States and the Netherlands and clinical officers elsewhere in Africa. The first ClinAs began their education in 2008 and started working in 2011. Three universities offer a 3-year bachelor of clinical medical practice degree. This article documents the nascent healthcare profession's origins, development, current status, and future. In the next decade, South Africa needs to address the challenges of ClinA supervision with tiered practice regulations, combat unemployment, and increase graduate retention by developing career paths.

Proposed task shifting integrated with telemedicine to address uncorrected refractive error in Kenya: Delphi study

BACKGROUND

Developing countries such as Kenya still experience challenges around human resource to deliver refractive error services. However, given the burden of uncorrected refractive error, adoption of innovative and cost effective approaches is desirable. Hence this study intended to develop a task shifting framework integrated with telemedicine to potentially scale refractive error services.

METHODS

This was an exploratory study conducted in four phases as follows: a scoping review of the scope of practice for ophthalmic workers in Kenya, an interview with key opinion leaders on the need for integration of public health approaches such as the vision corridors within the eye health ecosystem in Kenya and their knowledge on task shifting, and finally development and validation of a proposed task shifting framework through a Delphi technique. Purposive sampling was used to recruit key opinion leaders and data was collected via telephonic interviews. The qualitative data was analyzed thematically using NVivo Software, Version 11.

RESULTS

The scoping review showed that only optometrists, ophthalmologists and ophthalmic clinical officers are allowed to undertake refraction in Kenya. All of the key opinion leaders (100%) were aware of task shifting and agreed that it is suitable for adoption within the eye health ecosystem in Kenya. All of the key opinion leaders (100%) agreed that skills development for healthcare workers without prior training on eye health supervised by optometrists through telemedicine is desirable. Notwithstanding, all of the key opinion leaders (100%) agreed that integration of public health approaches such as the vision corridors across all levels of healthcare delivery channels and development of a self-assessment visual acuity tool is desirable. Finally all of the key opinion leaders (100%) agreed that task shifting is relevant for adoption within the eye health ecosystem in Kenya. The developed framework prioritized partnership, advocacy, skills development, establishment and equipping of refraction points. The proposed framework advocated for a telemedicine between professionals with conventional training and those with skills development.

CONCLUSION

Task shifting integrated with telemedicine could cost effectively scale refractive error service delivery. However, internal and external factors may hinder the success warranting the need for a multi-faceted interventions and a connection between planning and training to scale the uptake.

An exploration of the Indonesian lay mental health workers' (cadres) experiences in performing their roles in community mental health services: a qualitative study

BACKGROUND

Volunteers trained to support community mental health programs in Indonesia are known as 'mental health cadres.' These are lay people trained to provide basic support for people with mental illness in their local communities. The role of cadres in community mental health services is to provide health promotion activities and support for people with mental illness, such as home visits and family assistance. Their contribution can potentially address the challenges health services currently face in remote and resource-limited settings. However, little is currently known about implementing this form of the lay workforce and the experiences of mental health cadres in Indonesia in particular. This study aimed to explore the experience of cadres when performing their roles in community mental health services in Indonesia from the cadres' perspective.

METHODS

The study employed a descriptive qualitative design. Purposive sampling was employed to recruit cadres with at least one year of experience handling those diagnosed with schizophrenia across four geographical areas in Java and Sumatra, Indonesia. Data were collected utilising focus groups undertaken between July and November 2020. Due to COVID-19 restrictions, eight focus group sessions for mental health cadres were carried out virtually via Zoom and non-virtual, facilitated by local moderators. Data were analysed using thematic analysis.

RESULTS

The study involved 71 cadres in four regions: Aceh, Jakarta, West Java and East Java. The majority of participants were looking after their families with a minimum of high school-level qualifications. Four themes were interpreted from the data: (1) Motivation for volunteering, (2) The role of cadres in supporting mental health services, (3) Training and support needs in carrying out cadre roles, and (4) Barriers and facilitators to the implementation of cadre roles in local communities.

CONCLUSIONS

Cadres reported a motivation to help people improve their mental health and reduce the stigma associated with mental illness. Cadres also contributed to secondary and primary prevention of mental illness with some limitations. This study's results are relevant to those wishing to understand and optimise the implementation of lay workforces in resource-limited settings.

Barriers and facilitators to a task-shifted stroke prevention program for children with sickle cell anemia in a community hospital: a qualitative study

BACKGROUND

Children with sickle cell anemia (SCA) are at high risk for stroke. Protocols for stroke prevention including blood transfusions, screening for abnormal non-imaging transcranial Doppler (TCD) measurements, and hydroxyurea therapy are difficult to implement in low-resource environments like Nigeria. This study aimed to examine the contextual factors around TCD screening in a community hospital in Nigeria using qualitative interviews and focus groups.

METHODS

We conducted a descriptive qualitative study in a community hospital in Kaduna, Nigeria, using focus groups and interviews. Interview guides and analysis were informed by the Consolidated Framework for Implementation Research (CFIR) framework and the Theory of Planned Behavior. Transcripts were coded and analyzed using an iterative deductive (CFIR)/Inductive (transcribed quotes) qualitative methodology.

RESULTS

We conducted two focus groups and five interviews with health care workers (nurses and doctors) and hospital administrators, respectively. Themes identified key elements of the inner setting (clinic characteristics, resource availability, implementation climate, and tension for change), characteristics of individuals (normative, control, and behavioral beliefs), and the implementation process (engage, implement, and adopt), as well as factors that were influenced by external context, caregiver needs, team function, and intervention characteristics. Task shifting, which is already being used, was viewed by providers and administrators as a necessary strategy to implement TCD screening in a clinic environment that is overstressed and under-resourced, a community stressed by poverty, and a nation with an underperforming health system.

CONCLUSION

Task shifting provides a viable option to improve health care by making more efficient use of already available human resources while rapidly expanding the human resource pool and building capacity for TCD screening of children with SCD that is more sustainable.

Task Shifting: Need for a more Cautious and Nuanced Approach

Task shifting refers to the strategic redistribution and decentralization of health care tasks from one group to another(including lay workers), the latter usually deemed as having lesser training and qualifications, and is an approach that isutilized to address the shortage and imbalance of the health workforce within a certain geographic area, thereby ensuring apopulation’s access to care.1 Task shifting can involve extending the role of a particular group (enhancement), exchanging workbetween groups (substitution/delegation), or creation of new jobs (innovation).2 While the primary conceptualization of taskshifting is from professional to lay health workers, it must be stated that task shifting can also involve shifting of tasks fromprofessionals to patients; from health workers to technology; and between different types of health workers.2 Task shifting hasbeen implemented in a variety of settings and for different programs/conditions, such as HIV/AIDS treatment3, cancer care4,mental health5, ultrasonography for antenatal care6, surgical care7, and non-communicable disease management8, similar to thecontext of the report by Tamayo and Reyes9 in this issue of Acta Medica Philippina. In addition to bridging the health humanresources gap, it has been proposed that task shifting may address health equity by broadening access to essential health services,contribute to enhancing the quality of care that is aligned with the changing societal needs, and yield cost savings particularlyfor the delivery of routine activities.10,11 Despite its widespread application, touted benefits, and the seeming preference of many organizations to use task shiftinga default solution to the health workforce challenge, three things must be pointed out. First, task shifting should be properly seen as a temporary solution to the health workforce challenge confronting countriesand health systems.12,13 Better and more comprehensive planning and management of human resources for health at the systemlevel is needed so that we can address the underlying problems that resulted to the implementation of task shifting in the firstplace – shortage, maldistribution, skill-mix balance, and sub-optimal working conditions that are, in turn, driven, by both healthsystem and contextual factors.14 Second, in situations where task shifting is perceived to be the better policy alternative, the program should be implementedin an ethical manner, considering respect for persons (i.e., free and informed decision making to take part in task shifting,recognition of recipients of tasks as critical contributors to the health program), justice (i.e., adequate guidance and supervision,fair remuneration, minimization of undue burden), beneficence (i.e., promoting health and welfare of workers, minimizingharm to workers and communities), proportionality (i.e., assignment of workload and responsibility commensurate to skillsand resources available), and cultural humility (i.e., cultural competency and humility on the part of dominant institutions),especially when the recipient of tasks are volunteer community health workers.15 Lastly, task shifting should be implemented as a comprehensive package of interventions, rather than a single activity.At the outset, the necessary conditions and important considerations for launching a task shifting program should be present,as outlined in the Concepts and Opportunities to Advance Task Shifting and Task Sharing (COATS) Framework.16 The keyelements for successful implementation (i.e., collaboration and coordinated care, financing, patient preference, shared decisionmaking,provider empowerment, training and competency, clear process outcomes, and supportive organizational system) oftask shifting should also be present.17 Recommendations on how and when to adopt task shifting as a strategy have also beenpublished by various organizations such as the World Health Organization1 and the World Medical Association18. The success of a task shifting strategy will require, among others, that health workers be actively engaged in the process,ensuring that the planned task shifting is aligned with their personal values, and creating an enabling environment19 that willallow them to carry out their tasks effectively, efficiently, and in a safe manner. In short, one of the requirements is that, aspointed out in the paper by Tamayo and Reyes9, stakeholders find task shifting an acceptable strategy.

Cost-effectiveness of community-based household tuberculosis contact management for children in Cameroon and Uganda: a modelling analysis of a cluster-randomised trial

BACKGROUND

WHO recommends household contact management (HCM) including contact screening and tuberculosis-preventive treatment (TPT) for eligible children. The CONTACT trial found increased TPT initiation and completion rates when community health workers were used for HCM in Cameroon and Uganda.

METHODS

We did a cost-utility analysis of the CONTACT trial using a health-system perspective to estimate the health impact, health-system costs, and cost-effectiveness of community-based versus facility-based HCM models of care. A decision-analytical modelling approach was used to evaluate the cost-effectiveness of the intervention compared with the standard of care using trial data on cascade of care, intervention effects, and resource use. Health outcomes were based on modelled progression to tuberculosis, mortality, and discounted disability-adjusted life-years (DALYs) averted. Health-care resource use, outcomes, costs (2021 US$), and cost-effectiveness are presented.

FINDINGS

For every 1000 index patients diagnosed with tuberculosis, the intervention increased the number of TPT courses by 1110 (95% uncertainty interval 894 to 1227) in Cameroon and by 1078 (796 to 1220) in Uganda compared with the control model. The intervention prevented 15 (-3 to 49) tuberculosis deaths in Cameroon and 10 (-20 to 33) in Uganda. The incremental cost-effectiveness ratio was $620 per DALY averted in Cameroon and $970 per DALY averted in Uganda.

INTERPRETATION

Community-based HCM approaches can substantially reduce child tuberculosis deaths and in our case would be considered cost-effective at willingness-to-pay thresholds of $1000 per DALY averted. Their impact and cost-effectiveness are likely to be greatest where baseline HCM coverage is lowest.

Supporting the helpers: what do peer deliverers of HIV interventions need to sustain their implementation efforts?

Peer-led HIV interventions are an increasingly common and low-cost strategy to address shortages of professionally trained health workers for implementing evidence-based HIV prevention and treatment interventions to populations who experience health disparities. There is a need to understand the experiences and unmet needs of this essential workforce responsible for implementing and delivering HIV interventions to ensure their implementation efforts are sustainable. This commentary provides a brief overview of barriers to peer deliverers' sustained engagement in the HIV workforce and potential implementation strategies to promote the sustainment of peer deliverers' implementation efforts.

Uncovering Barriers to Engagement in Substance Use Disorder Care for Medicaid Enrollees

OBJECTIVE

The authors aimed to uncover factors that affect engagement in substance use disorder treatment among Medicaid beneficiaries in New York State.

METHODS

The authors conducted 40 semistructured interviews with clients, plan administrators, health care providers, and policy leaders directly involved with substance use care in New York State. Data were analyzed with thematic analysis.

RESULTS

Main themes resulting from analysis of the 40 interviews showed that most stakeholders agreed that a need exists to better integrate psychosocial services into behavioral health care systems; that systemic stigma, stigma from providers, and lack of cultural responsiveness in the substance use care system hinder engagement in and provision of high-quality care; and that rural health care networks with coordinated models benefit clients' engagement in care.

CONCLUSIONS

Stakeholders involved in care for substance use disorder perceived a lack of integration of resources to meet clients' social needs, the presence of stigma, and low levels of cultural and linguistic capacity as key factors contributing to low engagement in and low quality of care for substance use disorder. Future interventions should address social needs within the therapeutic regimen and modify curricula in clinical training to reduce stigma and increase cultural competence.

Calculating the Costs of Implementing Integrated Packages of Community Health Services: Methods, Experiences, and Results From 6 sub-Saharan African Countries

BACKGROUND

Ensuring access to a package of integrated primary health care services is essential for achieving universal health coverage. In many countries, community health programs are necessary for primary health care service provision, but they are generally underfunded, and countries often lack the necessary evidence on costs and resource requirements. We conducted prospective cost analyses of community health programs in 6 countries in sub-Saharan Africa using the Community Health Planning and Costing Tool.

METHODS

The Community Health Planning and Costing Tool is a spreadsheet-based tool designed to cost key programmatic elements of community health services packages, including training, equipment, incentives, supervision, and management. In each country, stakeholders defined a package of community health services and corresponding standard treatment guidelines to estimate normative costs, which were applied to program scale-up targets. The data were entered into the tool, and cost models were prepared for different geographical and service utilization scenarios. The results were reviewed and validated with the governments, implementing partners, and expert panels. Additional scale-up scenarios were modeled, taking into account probable constraints to increasing community health service provision and potential funding limitations.

RESULTS

The services and scope of community health service packages varied by country, depending on contextual factors and determined health priorities. The package costs also varied significantly depending on the size and contents of the service package, the service delivery approach, the remuneration of the community health workers, and the cost of medicines and supplies.

CONCLUSIONS

Community health programs and service packages are different in every country and change over time as they evolve. They should be routinely costed as an integral part of the planning and budgeting process and to ensure that sufficient resources are allocated for their effective and efficient implementation.

A community health worker-led program to improve access to gestational diabetes screening in urban slums of Pune, India: Results from a mixed methods study

The World Health Organization recommends all pregnant women receive screening for gestational diabetes (GDM) with a fasting oral glucose tolerance test (OGTT). However, very few women receive recommended screening in resource-limited countries like India. We implemented a community health worker (CHW)-delivered program to evaluate if home-based, CHW-delivered OGTT would increase GDM screening in a low-resource setting. We conducted a mixed methods study in two urban slum communities in Pune, India. CHWs were trained to deliver home-based, point-of-care fasting OGTT to women in their third trimester of pregnancy. The primary outcome was uptake of CHW-delivered OGTT. Secondary outcomes included GDM prevalence and linkage to GDM care. Individual interviews were conducted with purposively sampled pregnant women, CHWs, and local clinicians to assess barriers and facilitators of this approach. From October 2021-June 2022, 248 eligible pregnant women were identified. Of these, 223 (90%) accepted CHW-delivered OGTT and 31 (14%) were diagnosed with GDM. Thirty (97%) women diagnosed with GDM subsequently sought GDM care; only 10 (33%) received lifestyle counseling or pharmacologic therapy. Qualitative interviews indicated that CHW-delivered testing was considered highly acceptable as home-based testing saved time and was more convenient than clinic-based testing. Inconsistent clinical management of GDM was attributed to providers' lack of time to deliver counseling, and perceptions that low-income populations are not at risk for GDM. Convenience and trust in a CHW-delivered GDM screening program resulted in high access to gold-standard OGTT screening and identification of a high GDM prevalence among pregnant women in two urban slum communities. Appropriate linkage to care was limited by clinician time constraints and misperceptions of GDM risk. CHW-delivered GDM screening and counseling may improve health education and access to preventive healthcare, offloading busy public clinics in high-need, low-resource settings.

HIV Care Profiling and Delivery Status in the Mobile Health Clinics of eThekwini District in KwaZulu Natal, South Africa: A Descriptive Evaluation Study

Mobile health clinics (MHCs) serve as an alternative HIV care delivery method for the HIV-burdened eThekwini district. This study aimed to describe and profile the HIV care services provided by the MHCs through process evaluation. A descriptive cross-sectional quantitative evaluation study was performed on 137 MHCs using total population sampling. An online data collection method using a validated 50-item researcher-developed instrument was administered to professional nurses who are MHC team leaders, following ethical approval from the local university and departments of health. Descriptive statistics were used to analyze the data. The results described that HIV care services are offered in open spaces (43%), community buildings (37%), solid built buildings called health posts (15%), vehicles (9%), and tents (2%) with no electricity (77%), water (55%), and sanitation (64%). Adults (97%) are the main recipients of HIV care in MHCs (90%) offering antiretroviral therapy (95%). Staff, monitoring, and retaining care challenges were noted, with good linkage (91%) and referral pathways (n = 123.90%). In conclusion, the standardization and prioritization of HIV care with specific contextual practice guidelines are vital.

Predictors of cessation of exclusive breastfeeding according to the Cox regression model: survey of mothers of children aged 6-12 months, Thiès, Senegal

Introduction

even though exclusive breastfeeding (EBF) for up to six months is recognised as essential infant care, it is still insufficiently practiced. The objective of this study was to identify predictors of EBF cessation in Thiès.

Methods

this was a survival analysis of data collected using a cross-sectional procedure. Data collection took place from 2nd December 2019 to 21st January 2020. The study population consisted of mothers of children aged 6 to 12 months residing in Thiès and seen at the reference health centre of the Thiès Health District during infant vaccination sessions. The number of subjects was 400 mothers recruited using a systematic survey, with a sampling interval equal to two. Data were collected through a face-to-face interview. Predictive factors were identified using the Cox regression model. The adjusted hazard ratio (AHR) and its 95% confidence interval (95% CI) are calculated.

Results

the average age of the mothers was 27.08 ± 6.34 years. The proportion of mothers who breastfed their child within one hour of birth was 29.25%. The proportion of those who practiced EBF was 41.50%. The incidence density of EBF cessation was 14 person-months per 100 breastfeeding mothers. The median duration of EBF was 5 months. Lack of advice on EBF during antenatal care (AHR=1.42; 95% CI =1.08-1.85), sources of information other than health professionals (AHR =1.51; 95% CI =1.05-2.19), late initiation of EBF, i.e. breastfeeding beyond 24 hours after birth (AHR =1.53; 95% CI =1.02-2.28) and low level of knowledge about EBF (AHR =1.46; 95% CI =1.11-1.92) were significantly associated with early termination of EBF.

Conclusion

the promotion of EBF for up to six months will necessarily involve the promotion of prenatal consultations during which professionals should raise awareness among future mothers.

Task shifting and task sharing in the health sector in sub-Saharan Africa: evidence, success indicators, challenges, and opportunities

This review explores task shifting and task sharing in sub-Saharan African healthcare to address workforce shortages and cost-effectiveness. Task shifting allocates tasks logically, while task sharing involves more workers taking on specific duties. Challenges include supply chain issues, pay inadequacy, and weak supervision. Guidelines and success measures are lacking. Initiating these practices requires evaluating factors and ensuring sustainability. Task shifting saves costs but needs training and support. Task sharing boosts efficiency, enabling skilled clinicians to contribute effectively. To advance task shifting and sharing in the region, further research is needed to scale up effective initiatives. Clear success indicators, monitoring, evaluation, and learning plans, along with exploration of sustainability and appropriateness dimensions, are crucial elements to consider.

A novel approach to estimate the impact of health workforce investments on health outcomes through increased coverage of HIV, TB and malaria services

BACKGROUND

Globally, HIV, TB and malaria account for an estimated three million deaths annually. The Global Fund partnered with the World Health Organization to assist countries with health workforce planning in these areas through the development of an integrated health workforce investment impact tool. Our study illustrates the development of a user-friendly tool (with two MS Excel calculator subcomponents) that computes associations between human resources for health (HRH) investment inputs and reduced morbidity and mortality from HIV, TB, and malaria via increased coverage of effective treatment services.

METHODS

We retrieved from the peer-reviewed literature quantitative estimates of the relation among HRH inputs and HRH employment and productivity. We converted these values to additional full-time-equivalent doctors, nurses and midwives (DNMs). We used log-linear regression to estimate the relation between DNMs and treatment service coverage outcomes for HIV, TB, and malaria. We then retrieved treatment effectiveness parameters from the literature to calculate lives saved due to expanded treatment coverage for HIV, TB, and malaria. After integrating these estimates into the tool, we piloted it in four countries.

RESULTS

In most countries with a considerable burden of HIV, TB, and malaria, the health workforce investments include a mix of pre-service education, full remuneration of new hires, various forms of incentives and in-service training. These investments were associated with elevated HIV, TB and malaria treatment service coverage and additional lives saved. The country case studies we developed in addition, indicate the feasibility and utility of the tool for a variety of international and local actors interested in HRH planning.

CONCLUSIONS

The modelled estimates developed for illustrative purposes and tested through country case studies suggest that HRH investments result in lives saved across HIV, TB, and malaria. Furthermore, findings show that attainment of high targets of specific treatment coverage indicators would require a substantially greater health workforce than what is currently available in most LMICs. The open access tool can assist with future HRH planning efforts, particularly in LMICs.

Preliminary evaluation of dual-energy CT to quantitatively assess bone marrow edema in patients with diabetic foot ulcers and suspected osteomyelitis

OBJECTIVES

The purpose of this study is to evaluate the value of dual-energy CT (DECT) with virtual non-calcium (VNCa) in quantitatively assessing the presence of bone marrow edema (BME) in patients with diabetic foot ulcers and suspected osteomyelitis.

METHODS

Patients with a diabetic foot ulcer and suspected osteomyelitis that underwent DECT (80 kVp/Sn150 kVp) with VNCa were retrospectively included. Two observers independently measured CT values of the bone adjacent to the ulcer and a reference bone not related to the ulcer. The patients were divided into two clinical groups, osteomyelitis or no-osteomyelitis, based on the final diagnosis by the treating physicians.

RESULTS

A total of 56 foot ulcers were identified of which 23 were included in the osteomyelitis group. The mean CT value at the ulcer location was significantly higher in the osteomyelitis group (- 17.23 ± 34.96 HU) compared to the no-osteomyelitis group (- 69.34 ± 49.40 HU; p < 0.001). Within the osteomyelitis group, the difference between affected bone and reference bone was statistically significant (p < 0.001), which was not the case in the group without osteomyelitis (p = 0.052). The observer agreement was good for affected bone measurements (ICC = 0.858) and moderate for reference bone measurements (ICC = 0.675). With a cut-off value of - 40.1 HU, sensitivity was 87.0%, specificity was 72.7%, PPV was 69.0%, and NPV was 88.9%.

CONCLUSION

DECT with VNCa has a potential value for quantitatively assessing the presence of BME in patients with diabetic foot ulcers and suspected osteomyelitis.

KEY POINTS

• Dual-energy CT (DECT) with virtual non-calcium (VNCa) is promising for detecting bone marrow edema in the case of diabetic foot ulcers with suspected osteomyelitis. • DECT with VNCa has the potential to become a more practical alternative to MRI in assessing the presence of bone marrow edema in suspected osteomyelitis when radiographs are not sufficient to form a diagnosis.

A Mobile Clinical Decision Support System for High-Risk Pregnant Women in Rural India (SMARThealth Pregnancy): Pilot Cluster Randomized Controlled Trial

BACKGROUND

Cardiovascular disease (CVD) is the leading cause of death in women in India. Early identification is crucial to reducing deaths. Hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM) carry independent risks for future CVD, and antenatal care is a window to screen and counsel high-risk women. In rural India, community health workers (CHWs) deliver antenatal and postnatal care. We developed a complex intervention (SMARThealth Pregnancy) involving mobile clinical decision support for CHWs and evaluated it in a pilot cluster randomized controlled trial (cRCT).

OBJECTIVE

The aim of the study is to co-design a theory-informed intervention for CHWs to screen, refer, and counsel pregnant women at high risk of future CVD in rural India and evaluate its feasibility and acceptability.

METHODS

In phase 1, we used qualitative methods to explore community priorities for high-risk pregnant women in rural areas of 2 diverse states in India. In phase 2, informed by behavior change theory and human-centered design, we used these qualitative data to develop the intervention components and implementation strategies for SMARThealth Pregnancy in an iterative process with end users. In phase 3, using mixed methods, we evaluated the intervention in a cRCT with an embedded qualitative substudy across 4 primary health centres: 2 in Jhajjar district, Haryana, and 2 in Guntur district, Andhra Pradesh.

RESULTS

SMARThealth Pregnancy embedded a total of 15 behavior change techniques and included (1) community awareness programs; (2) targeted training, including point-of-care blood pressure and hemoglobin measurement; and (3) mobile clinical decision support for CHWs to screen women in their homes. The intervention focused on 3 priority conditions: anemia, HDP, and GDM. The evaluation involved a total of 200 pregnant women, equally randomized to intervention or enhanced standard care (control). Recruitment was completed within 5 months, with minimal loss to follow-up (4/200, 2%) at 6 weeks postpartum. A total of 4 primary care doctors and 54 CHWs in the intervention clusters took part in the study. Fidelity to intervention practices was 100% prepandemic. Over half the study population was affected by moderate to severe anemia at baseline. The prevalence of HDP (2.5%) and GDM (2%) was low in our study population. Results suggest a possible improvement in mean hemoglobin (anemia) in the intervention group, although an adequately powered trial is needed. The model of home-based care was feasible and acceptable for pregnant or postpartum women and CHWs, who perceived improvements in quality of care, self-efficacy, and professional recognition.

CONCLUSIONS

SMARThealth Pregnancy is an innovative model of home-based care for high-risk pregnant women during the transitions between antenatal and postnatal care and adult health services. The use of theory and co-design during intervention development facilitated acceptability of the intervention and implementation strategies. Our experience has informed the decision to initiate a larger-scale cRCT.

Barriers and Facilitators to a Task-Shifted Stroke Prevention Program for Children with Sickle Cell Anemia in a Community Hospital: A Qualitative Study

Background

Children with sickle cell anemia (SCA) are at high risk for stroke. Protocols for stroke prevention including blood transfusions, screening for abnormal non-imaging transcranial Doppler (TCD) measurements, and hydroxyurea therapy are difficult to implement in low-resource environments like Nigeria. This study aimed to examine the contextual factors around TCD screening in a community hospital in Nigeria using qualitative interviews and focus groups.

Methods

We conducted focus groups with health care providers and interviews with administrative leadership of the community hospital. Interview guides and analysis were informed by the Consolidated Framework for Implementation Research (CFIR) framework. Transcripts were coded and analyzed using an iterative deductive (CFIR)/Inductive (transcribed quotes) qualitative methodology.

Results

We conducted two focus groups and five interviews with health care workers (nurses and doctors) and hospital administrators, respectively. Themes identified key elements of the inner setting (clinic characteristics, resource availability, implementation climate, and tension for change), characteristics of individuals (normative, control, and behavioral beliefs), and the implementation process (engage, implement, and adopt), as well as factors that were influenced by external context, caregiver needs, team function, and intervention characteristics. Task shifting, which is already being used, was viewed by providers and administrators as a necessary strategy to implement TCD screening in a clinic environment that is overstressed and under-resourced, a community stressed by poverty, and a nation with an underperforming health system.

Conclusion

Task shifting provides a viable option to improve health care by making more efficient use of already available human resources while rapidly expanding the human resource pool and building capacity that is more sustainable.

Short-Term Impact of "Amaka Amasanyufu" Multiple Family Group Intervention on Mental Health Functioning of Children With Disruptive Behavior Disorders in Uganda

OBJECTIVE

We evaluate the mid-intervention (8 weeks) and short-term (16 weeks) impact of a culturally adapted multiple family group (MFG) intervention, "Amaka Amasanyufu," on the mental health of children with disruptive behavior disorders (DBDs) and primary caregivers in Uganda.

METHOD

We analyzed data from the Strengthening mental health and research training in Sub-Saharan Africa (SMART) Africa-Uganda study. Schools were randomized to the following: a control group; an MFG facilitated by parent peers (MFG-PP); or an MFG facilitated by community health workers (MFG:CHW). All participants were blinded to interventions provided to other participants and study hypotheses. At 8 weeks and 16 weeks, we evaluated differences in depressive symptoms and self-concept among children and in mental health and caregiving-related stress among caregivers. Three-level linear mixed-effects models were fitted. Pairwise comparisons of post-baseline group means were performed using the Sidak adjustment for multiple comparisons and standardized mean differences. Data from 636 children with DBDs and caregivers (controls: n = 243, n = 10 schools; MFG-PP: n = 194, n = 8 schools; MFG-CHW: n = 199, n = 8 schools) were analyzed.

RESULTS

There were significant group-by-time interactions for all outcomes, and differences were observed mid-intervention, with short-term effects at 16 weeks (end-intervention). MFG-PP and MFG-CHW children had significantly lower depressive symptoms and higher self-concept, whereas caregivers had significantly lower caregiving-related stress and fewer mental health problems, than controls. There was no difference between intervention groups.

CONCLUSION

Amaka Amasanyufu MFG intervention is effective for reducing depressive symptoms and improving self-concept among children with DBDs while reducing parental stress and mental health problems among caregivers. Given the paucity of culturally adapted mental health interventions, this provides support for adaptation and scale-up in Uganda and other low-resource settings.

Seizure Safari: Bridging the Treatment Gap in Rural Tanzania and Shaking Up Epilepsy Care

Does the Presence of a Specialist Doctor Reduce the Burden of Disease in People With Epilepsy in Low-Resource Settings? A Comparison of Two Epilepsy Clinics in Rural Tanzania Klein A, Berger TC, Hapfelmeier A, Schaffert M, Matuja W, Schmutzhard E, Winkler AS. Epilepsy Behav. 2023;139:109030. doi:10.1016/j.yebeh.2022.109030 Background: With an estimated lifetime prevalence of epilepsy of 7.6 per 1,000 people, epilepsy represents one of the most common neurological disorders worldwide, with the majority of people with epilepsy (PWE) living in low-income and middle-income countries (LMICs). Adequately treated, up to 70% of PWE will become seizure-free, however, as many as 85% of PWE worldwide, mostly from LMICs, do not receive adequate treatment. Objective: To assess the impact of the presence of a neurologist on the management of PWE in Tanzania. Methods: Two epilepsy clinics in rural Tanzania, one continuously attended by a neurologist, and one mainly attended by nurses with training in epilepsy and supervised intermittently by specialist doctors (neurologists/psychiatrists) were comparatively analyzed by multivariable linear and logistic regression models with regard to the outcome parameters seizure frequency, the occurrence of side effects of antiepileptic medication and days lost after a seizure. Results: The presence of a neurologist significantly reduced the mean number of seizures patients experienced per month by 4.49 seizures (p < 0.01) while leading to an increase in the occurrence of reported side effects (OR: 2.15, p = 0.02). Conclusion: The presence of a neurologist may play a substantial role in reducing the burden of the disease of PWE in LMICs. Hence, specialist training should be encouraged, and relevant context-specific infrastructure established.

Leveraging community health workers as vaccinators: a case study exploring the role of Malawi's Health Surveillance Assistants in delivering routine immunization services

BACKGROUND

Global chronic health worker shortages and stagnating routine immunization rates require new strategies to increase vaccination coverage and equity. As trained, trusted members of their local communities, community health workers (CHWs) are in a prime position to expand the immunization workforce and increase vaccination coverage in under-reached communities. Malawi is one of only a few countries that relies on CHWs-called Health Surveillance Assistants (HSAs) in Malawi-to administer routine immunizations, and as such offers a unique example of how this can be done.

CASE PRESENTATION

We sought to describe the operational and programmatic characteristics of a functional CHW-led routine immunization program by conducting interviews with HSAs, HSA supervisors, ministry of health officials, and community members in Malawi. This case study describes how and where HSAs provide vaccinations, their vaccination-related responsibilities, training and supervision processes, vaccine safety considerations, and the community-level vaccine supply chain. Interview participants consistently described HSAs as a high-functioning vaccination cadre, skilled and dedicated to increasing vaccine access for children. They also noted a need to strengthen some aspects of professional support for HSAs, particularly related to training, supervision, and supply chain processes. Interviewees agreed that other countries should consider following Malawi's example and use CHWs to administer vaccines, provided they can be sufficiently trained and supported.

CONCLUSIONS

This account from Malawi provides an example of how a CHW-led vaccination program operates. Leveraging CHWs as vaccinators is a promising yet under-explored task-shifting approach that shows potential to help countries maximize their health workforce, increase vaccination coverage and reach more zero-dose children. However, more research is needed to produce evidence on the impact of leveraging CHWs as vaccinators on patient safety, immunization coverage/vaccine equity, and cost-effectiveness as compared to use of other cadres for routine immunization.

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.

Culturally adapted family intervention for people with schizophrenia in Indonesia (FUSION): a development and feasibility study protocol

Background

Mental illnesses comprise the single largest source of health-related economic burden globally, and low- and middle-income countries are disproportionately affected. The majority of people with schizophrenia who need treatment do not receive it and are often wholly reliant on family caregivers for daily care and support. Family interventions have an exceptionally robust evidence base for their efficacy in high-resource settings, but it is unknown whether they can produce equivalent effects in some low-resource settings where cultural beliefs, explanatory models of illness and contextual socio-economic issues differ.

Methods

This protocol describes the methods for a randomised controlled trial to determine the feasibility of testing culturally adapt and refine an evidence-based, family intervention for relatives and caregivers of people with schizophrenia in Indonesia. The feasibility and acceptability of implementing our adapted, co-produced intervention via task shifting in primary care settings will be evaluated using the Medical Research Council framework for complex interventions. We will recruit 60 carer-service-user dyads and randomise them in a 1:1 ratio either to receive our manualised intervention or continue to receive treatment as usual. Healthcare workers in primary care settings will be trained to deliver family interventions using our manualised intervention by a family intervention specialist. Participants will complete the ECI, IEQ, KAST and GHQ. Service-user symptom level and relapse status will be measured using the PANSS at baseline, post-intervention and 3 months later by trained researchers. Fidelity to the intervention model will be measured using the FIPAS. Qualitative evaluation will further assist with refining the intervention, evaluating trial processes and evaluating acceptability.

Discussion

National healthcare policy in Indonesia supports the delivery of mental health services in a complex network of primary care centres. This study will provide important information on the feasibility of delivering family interventions for people with schizophrenia via task shifting in primary care settings in Indonesia and allow further refinement of the intervention and trial processes.

Nursing Workforce Optimization Study: A Multi-method Evaluation and Process Improvement Intervention for HIV Service Delivery in Tanzania and Zambia

ABSTRACT

Nurses are often suboptimally used in HIV care, due to misalignment of training and practice, workflow inefficiencies, and management challenges. We sought to understand nursing workforce capacity and support implementation of process improvement strategies to improve efficiency of HIV service delivery in Tanzania and Zambia. We conducted time and motion observations and task analyses at 16 facilities followed by process improvement workshops. On average, each nurse cared for 45 clients per day in Tanzania and 29 in Zambia. Administrative tasks and documentation occupied large proportions of nurse time. Self-reported competency was low at baseline and higher at follow-up for identifying and managing treatment failure and prescribing antiretroviral therapy. After workshops, facilities changed care processes, provided additional training and mentorship, and changed staffing and supervision. Efficiency outcomes were stable despite staffing increases. Collaborative approaches to use workforce data to engage providers in improvement strategies can support roll-out of nurse-managed HIV treatment.

Does the presence of a specialist doctor reduce the burden of disease in people with epilepsy in low-resource settings? A comparison of two epilepsy clinics in rural Tanzania

BACKGROUND

With an estimated lifetime prevalence of epilepsy of 7.6 per 1,000 people, epilepsy represents one of the most common neurological disorders worldwide, with the majority of people with epilepsy (PWE) living in low-income and middle-income countries (LMICs). Adequately treated, up to 70 % of PWE will become seizure-free, however, as many as 85% of PWE worldwide, mostly from LMICs, do not receive adequate treatment.

OBJECTIVE

To assess the impact of the presence of a neurologist on the management of PWE in Tanzania.

METHODS

Two epilepsy clinics in rural Tanzania, one continuously attended by a neurologist, and one mainly attended by nurses with training in epilepsy and supervised intermittently by specialist doctors (neurologists/psychiatrists) were comparatively analyzed by multivariable linear and logistic regression models with regard to the outcome parameters seizure frequency, the occurrence of side effects of antiepileptic medication and days lost after a seizure.

RESULTS

The presence of a neurologist significantly reduced the mean number of seizures patients experienced per month by 4.49 seizures (p < 0.01) while leading to an increase in the occurrence of reported side effects (OR: 2.15, p = 0.02).

CONCLUSION

The presence of a neurologist may play a substantial role in reducing the burden of the disease of PWE in LMICs. Hence, specialist training should be encouraged, and relevant context-specific infrastructure established.

Medical stakeholder perspectives on implementing a computerized battery to identify neurocognitive impairments among youth in Botswana

HIV infection and in utero exposure, common in Sub-Saharan Africa, are associated with pediatric neurocognitive impairment. Cognitive screening can identify impairments, but it is rarely used in this setting. The Penn Computerized Neurocognitive Battery (PennCNB), an evidence-based cognitive screening tool, was adapted for use in Botswana. To facilitate future implementation, 20 semi-structured interviews were conducted to elicit key stakeholders' perspectives on factors likely to be related to successful uptake of the PennCNB in clinical settings. An integrated analytic approach combining constructs from the Consolidated Framework for Implementation Research and modified grounded theory was used. Results underscore the need for cognitive screening in Botswana and the acceptability of the PennCNB. Implementation barriers include limited time and resources, whereas facilitators include standard procedures for introducing new tools into medical settings and for training implementers. Recommended implementation strategies include integrating screening into the existing workflow, implementing the tool in the medical and educational sectors, and targeting selection of children for assessment. This research addresses the research-to-practice gap by engaging in pre-implementation inquiry and designing for implementation. Results will inform the development of strategies to maximize the likelihood of successful implementation of the PennCNB to identify neurocognitive impairment in children in this high-need setting.

Human resource needs and costs for HIV pre-exposure prophylaxis provision in nurse-led primary care in Eswatini and opportunities for task sharing

BACKGROUND

The global expansion of HIV pre-exposure prophylaxis (PrEP) includes health systems that face a shortage of skilled health care workers (HCWs). We estimated the human resource needs and costs for providing PrEP in nurse-led primary care clinics in Eswatini. Furthermore, we assessed potential cost savings from task sharing between nurses and other HCW cadres.

METHODS

We conducted a time-and-motion and costing study in a PrEP demonstration project between August 2017 and January 2019. A form for recording time and performed activities ("motion") was filled by HCWs of six primary care clinics. To estimate the human resource needs for specific PrEP activities, we allocated recorded times to performed PrEP activities using linear regression with and without adjusting for a workflow interruption, that is, if a client was seen by different HCWs or by the same HCW at different times. We assessed a base case in which a nurse provides all PrEP activities and five task shifting scenarios, of which four include workflow interruptions due to task sharing between different HCW cadres.

RESULTS

On average, PrEP initiation required 29 min (95% CI 25-32) of HCW time and PrEP follow-up 16 min (95% CI 14-18). The HCW time cost $4.55 (uncertainty interval [UI] 1.52-9.69) for PrEP initiation and $2.54 (UI 1.07-4.64) for PrEP follow-up when all activities were performed by a nurse. Time costs were $2.30-4.25 (UI 0.62-9.19) for PrEP initiation and $1.06-2.60 (UI 0.30-5.44) for PrEP follow-up when nurses shared tasks with HCWs from lower cadres. Interruptions of the workflow added, on average, 3.4 min (95% CI 0.69-6.0) to the time HCWs needed for a given number of PrEP activities. The cost of an interrupted workflow was estimated at $0.048-0.87 (UI 0.0098-1.63) depending on whose time need increased.

CONCLUSIONS

A global shortage of skilled HCWs could slow the expansion of PrEP. Task shifting to lower-cadre HCW in nurse-led PrEP provision can free up nurse time and reduce the cost of PrEP provision even if interruptions associated with task sharing increase the overall human resource need.

Results from an effectiveness-implementation evaluation of a postpartum depression prevention intervention delivered in home visiting programs

BACKGROUND

Building on growing research examining lay health professionals delivering postpartum depression preventive interventions, we conducted a hybrid effectiveness-implementation Type 2 trial to examine implementation metrics and determine whether pregnant women receiving Mothers and Babies 1-on-1 delivered by lay home visitors exhibit greater reductions in depressive symptoms and perceived stress than women receiving usual home visiting.

METHODS

1229 (672 control, 557 intervention) pregnant women were enrolled, with intervention participants receiving Mothers and Babies 1-on-1 delivered by a lay home visitor and control participants receiving usual home visiting services. Baseline and six-month follow-up assessments measured client mental health outcomes, with management information system data collected to assess intervention dosage. Surveys were administered nine months post-training to agency managers as well as home visitors who delivered any intervention content.

RESULTS

Intent-to-treat analyses indicated a significant reduction in perceived stress among intervention participants compared to controls, while as-treated analyses showed significant reductions in perceived stress and depressive symptoms. Although all study sites adopted the intervention, <50 % of eligible women received the intervention. Over two-thirds of home visitors made at least one fidelity-consistent adaptation, with client recruitment and retention in home visiting highlighted as challenges to delivery.

LIMITATIONS

Unmeasured historical events may have affected study outcomes and caution should be used generalizing to perinatal women from different racial/ethnic groups and home visiting models.

CONCLUSION

Mothers and Babies 1-on-1 delivered by lay home visitors leads to reductions in perceived stress and depressive symptoms, suggesting task shifting to non-mental health professionals is viable when appropriate training and supervision is provided.

Systematic Review of Policies and Interventions to Prevent Sexual Harassment in the Workplace in Order to Prevent Depression

BACKGROUND

Sexual harassment in the workplace (SHWP) is highly prevalent and has a negative impact, including depression, on its victims, as well as a negative economic impact resulting from absenteeism and low productivity at work. This paper aims to outline the available evidence regarding the prevention of depressive symptoms among workers through policies and interventions that are effective in preventing SHWP.

METHODS

We conducted two systematic reviews. The first focused on the association of depression and SHWP, and the second on policies and interventions to prevent SHWP. We conducted a meta-analysis and a narrative synthesis, respectively. We identified 1831 and 6107 articles for the first and second review. After screening, 24 and 16 articles were included, respectively.

RESULTS

Meta-analysis results show a prevalence of depression of 26%, as well as a 2.69 increased risk of depression among workers who experience SHWP. Variables such as number of harassment experiences and exposure to harassment from coworkers and other people increase this risk.

CONCLUSIONS

There is limited evidence regarding the effectiveness of policies and training to prevent SHWP, mostly focused on improvements in workers' knowledge and attitudes about SHWP. However, there is no available evidence regarding its potential impact on preventing depression.
