The Use of Community Health Workers in Community Health Centers.

BACKGROUND: Until 2016, community health centers (CHCs) reported community health workers (CHWs) as part of their overall enabling services workforce, making analyses of CHW use over time infeasible in the annual Uniform Data System (UDS). OBJECTIVE: The objective of this study was to examine changes in the CHW workforce among CHCs from 2016 to 2018 and factors associated with the use of CHWs. RESEARCH DESIGN, SUBJECTS, MEASURES: The two-part model estimated separate effects for the probability of using any CHW and extent of CHW full-time equivalents (FTEs) reported in those CHCs, using a total of 4102 CHC-year observations from 2016 to 2018. To estimate the extent to which increases in CHW workforce are attributable to real growth or rather are a consequence of a change in reporting category, we also conducted a difference-in-differences analysis to compare non-CHW enabling services FTEs between CHCs with and without CHWs before (2013-2015) and after (2016-2018) the reporting change in 2016. RESULTS: The rate of CHCs that employed CHWs rose from 20.04% in 2016 to 28.34% in 2018, while average FTEs stayed relatively flat (3.32 FTEs). Patient visit volume (larger CHCs) and grant funding (less reliant on federal but more reliant on private funding) were significant factors associated with CHW use. However, we found that a substantial portion of this growth was attributable to a change in UDS reporting categories. CONCLUSION: While we do not address the reasons why CHCs have been slow to use CHWs, our results point to substantial financial barriers associated with CHCs' expanding the use of CHWs.

Using recruitment and selection to build a primary care workforce for the future.

Recruitment and selection are critical components of human resource management. They influence both the quantity and quality of the healthcare workforce. In this article, we use two different examples of primary care workers, General Practitioners in the UK and Community Health Workers in low- and middle- income countries, to illustrate how recruitment and selection are, and could be, used to enhance the primary care workforce in each setting. Both recruitment and selection can be costly, so when funding is limited, decisions on how to spend the human resources budget must be made. It could be argued that human resource management should focus on recruitment in a seller's market (an insufficient supply of applicants) and on selection in a buyer's market (sufficient applicants but concerns about their quality). We use this article to examine recruitment and selection in each type of market and highlight the interactions between these two human resource management decisions. Recruitment and selection, we argue, must be considered in both types of market; particularly in sectors where workers' labour impacts upon population health. We note the paucity of high-quality research in recruitment and selection for primary care and the need for rigorous study designs such as randomised trials.

Shifting the burden or expanding access to care? Assessing malaria trends following scale-up of community health worker malaria case management and reactive case detection.

BACKGROUND: Malaria is a significant burden to health systems and is responsible for a large proportion of outpatient cases at health facilities in endemic regions. The scale-up of community management of malaria and reactive case detection likely affect both malaria cases and outpatient attendance at health facilities. Using health management information data from 2012 to 2013 this article examines health trends before and after the training of volunteer community health workers to test and treat malaria cases in Southern Province, Zambia. RESULTS: An estimated 50% increase in monthly reported malaria infections was found when community health workers were involved with malaria testing and treating in the community (incidence rate ratio 1.52, p < 0.001). Furthermore, an estimated 6% decrease in outpatient attendance at the health facility was found when community health workers were involved with malaria testing and treating in the community. CONCLUSIONS: These results suggest a large public health benefit to both community case management of malaria and reactive case detection. First, the capacity of the malaria surveillance system to identify malaria infections was increased by nearly one-third. Second, the outpatient attendance at health facilities was modestly decreased. Expanding the capacity of the malaria surveillance programme through systems such as community case management and reactive case detection is an important step toward malaria elimination.

Development of a theory and evidence-based program to promote community treatment of fevers in children under five in a rural district in Southern Ghana: An intervention mapping approach.

BACKGROUND: This paper describes the development and implementation of a program to promote prompt and appropriate care seeking for fever in children under the age of five. Designed as a multicomponent program, the intervention comprises elements to influence the behavior of caregivers of children, Community Health Workers, professional health care providers and the wider community. METHODS: Following the six fundamental steps of the Intervention Mapping protocol, we involved relevant stakeholders from the commencement of planning to program end. The IM protocol also recommends various behavior change methods to guide intervention development. RESULTS: The intervention components implemented were successful in achieving program goals. For example, the intervention resulted in the primary outcome of reductions in all-cause mortality of 30% and 44%, among children treated with an antimalarial and those treated with the antimalarial plus an antibiotic respectively. Most Community Health Workers were retained on the program, with an attrition rate of 21.2% over a period of 30 months and the Community Health Workers rate of adherence to performance guidelines was high at 94.6%. CONCLUSION: We were able to systematically develop a theory- and evidence-based health promotion program based on the Intervention Mapping protocol. This article contributes to the response to recent calls for a more detailed description of the development of interventions and trials. The intervention mapping approach can serve as a guide for others interested in developing community- based health interventions in similar settings.

SafeMed: Using pharmacy technicians in a novel role as community health workers to improve transitions of care.

OBJECTIVES: To describe the design, implementation, and early experience of the SafeMed program, which uses certified pharmacy technicians in a novel expanded role as community health workers (CPhT-CHWs) to improve transitions of care. SETTING: A large nonprofit health care system serving the major medically underserved areas and geographic hotspots for readmissions in Memphis, TN. PRACTICE INNOVATION: The SafeMed program is a care transitions program with an emphasis on medication management designed to use low-cost health workers to improve transitions of care from hospital to home for superutilizing patients with multiple chronic conditions and polypharmacy. EVALUATION: CPhT-CHWs were given primary responsibility for patient outreach after hospital discharge with the use of home visits and telephone follow-up. SafeMed program CPhT-CHWs served as pharmacist extenders, obtaining medication histories, assisting in medication reconciliation and identification of potential drug therapy problems (DTPs), and reinforcing medication education previously provided by the pharmacist per protocol. RESULTS: CPhT-CHW training included patient communication skills, motivational interviewing, medication history taking, teach-back techniques, drug disposal practices, and basic disease management. Some CPhT-CHWs experienced difficulties adjusting to an expanded scope of practice. Nonetheless, once the Tennessee Board of Pharmacy affirmed that envisioned SafeMed CPhT-CHW roles were consistent with Board rules, additional responsibilities were added for CPhT-CHWs to enhance their effectiveness. Patient outreach teams including CPhT-CHWs achieved increases in home visit and telephone follow-up rates and were successful in helping identify potential DTPs. CONCLUSION: The early experience of the SafeMed program demonstrates that CPhT-CHWs are well suited for novel expanded roles to improve care transitions for superutilizing populations. CPhT-CHWs can identify and report potential DTPs to the pharmacist to help target medication therapy management. Critical success factors include strong CPhT-CHW patient-centered communication skills and strong pharmacist champions. In collaboration with state pharmacy boards and pharmacist associations, the SafeMed CPhT-CHW model can be successfully scaled to serve superutilizing patients throughout the country.

Healthcare Professional Shortage and Task-Shifting to Prevent Cardiovascular Disease: Implications for Low- and Middle-Income Countries.

Cardiovascular diseases (CVD) account for 18 million of annual global deaths with more than three quarters of these deaths occurring in low- and middle-income countries (LMIC). In LMIC, the distribution of risk factors is heterogeneous, with urban areas being the worst affected. Despite the availability of effective CVD interventions in developed countries, many poor countries still struggle to provide care due to lack of resources. In addition, many LMIC suffer from staff shortages which pose additional burden to the healthcare system. Regardless of these challenges, there are potentially effective strategies such as task-shifting which have been used for chronic conditions such as HIV to address the human resource crisis. We propose that through task-shifting, certain tasks related to prevention be shifted to non-physician health workers as well as non-nurse health workers such as community health workers. Such steps will allow better coverage of segments of the underserved population. We recognise that for task-shifting to be effective, issues such as clearly defined roles, evaluation, on-going training, and supervision must be addressed.

Community-based approaches and partnerships: innovations in health-service delivery in Bangladesh.

In Bangladesh, rapid advancements in coverage of many health interventions have coincided with impressive reductions in fertility and rates of maternal, infant, and childhood mortality. These advances, which have taken place despite such challenges as widespread poverty, political instability, and frequent natural disasters, warrant careful analysis of Bangladesh's approach to health-service delivery in the past four decades. With reference to success stories, we explore strategies in health-service delivery that have maximised reach and improved health outcomes. We identify three distinctive features that have enabled Bangladesh to improve health-service coverage and health outcomes: (1) experimentation with, and widespread application of, large-scale community-based approaches, especially investment in community health workers using a doorstep delivery approach; (2) experimentation with informal and contractual partnership arrangements that capitalise on the ability of non-governmental organisations to generate community trust, reach the most deprived populations, and address service gaps; and (3) rapid adoption of context-specific innovative technologies and policies that identify country-specific systems and mechanisms. Continued development of innovative, community-based strategies of health-service delivery, and adaptation of new technologies, are needed to address neglected and emerging health challenges, such as increasing access to skilled birth attendance, improvement of coverage of antenatal care and of nutritional status, the effects of climate change, and chronic disease. Past experience should guide future efforts to address rising public health concerns for Bangladesh and other underdeveloped countries.

Effectiveness of diabetes and hypertension management by rural primary health-care workers (Behvarz workers) in Iran: a nationally representative observational study.

BACKGROUND: Non-communicable diseases and their risk factors are leading causes of disease burden in Iran and other middle-income countries. Little evidence exists for whether the primary health-care system can effectively manage non-communicable diseases and risk factors at the population level. Our aim was to examine the effectiveness of the Iranian rural primary health-care system (the Behvarz system) in the management of diabetes and hypertension, and to assess whether the effects depend on the number of health-care workers in the community. METHODS: We used individual-level data from the 2005 Non-Communicable Disease Surveillance Survey (NCDSS) for fasting plasma glucose (FPG) and systolic blood pressure (SBP), body-mass index, medication use, and sociodemographic variables. Data for Behvarz-worker and physician densities were from the 2006 Population and Housing Census and the 2005 Outpatient Care Centre Mapping Survey. We assessed the effectiveness of treatment on FPG and SBP, and associations between FPG or SBP and Behvarz-worker density with two statistical approaches: a mixed-effects regression analysis of the full NCDSS sample adjusting for individual-level and community-level covariates and an analysis that estimated average treatment effect on data balanced with propensity score matching. RESULTS: NCDSS had data for 65,619 individuals aged 25 years or older (11,686 of whom in rural areas); of these, 64,694 (11,521 in rural areas) had data for SBP and 50,202 (9337 in rural areas) had data for FPG. Nationally, 39·2% (95% CI 37·7 to 40·7) of individuals with diabetes and 35·7% (34·9 to 36·5) of those with hypertension received treatment, with higher treatment coverage in women than in men and in urban areas than in rural areas. Treatment lowered mean FPG by an estimated 1·34 mmol/L (0·58 to 2·10) in rural areas and 0·21 mmol/L (-0·15 to 0·56) in urban areas. Individuals in urban areas with hypertension who received treatment had 3·8 mm Hg (3·1 to 4·5) lower SBP than they would have had if they had not received treatment; the treatment effect was 2·5 mm Hg (1·1 to 3·9) lower FPG in rural areas. Each additional Behvarz worker per 1000 adults was associated with a 0·09 mmol/L (0·01 to 0·18) lower district-level average FPG (p=0·02); for SBP this effect was 0·53 mm Hg (-0·44 to 1·50; p=0·28). Our findings were not sensitive to the choice of statistical method. INTERPRETATION: Primary care systems with trained community health-care workers and well established guidelines can be effective in non-communicable disease prevention and management. Iran's primary care system should expand the number and scope of its primary health-care worker programmes to also address blood pressure and to improve performance in areas with few primary care personnel. FUNDING: None.

Factors influencing the provision of public health services by village doctors in Hubei and Jiangxi provinces, China.

PROBLEM: The Chinese central government launched the Health System Reform Plan in 2009 to strengthen disease control and health promotion and provide a package of basic public health services. Village doctors receive a modest subsidy for providing public health services associated with the package. Their beliefs about this subsidy and providing public health services could influence the quality and effectiveness of preventive health services and disease surveillance. APPROACH: To understand village doctors' perspectives on the subsidy and their experiences of delivering public health services, we performed 10 focus group discussions with village doctors, 12 in-depth interviews with directors of township health centres and 4 in-depth interviews with directors of county-level Centers for Disease Control and Prevention. LOCAL SETTING: The study was conducted in four counties in central China, two in Hubei province and two in Jiangxi province. RELEVANT CHANGES: Village doctors prioritize medical services but they do their best to manage their time to include public health services. The willingness of township health centre directors and village doctors to provide public health services has improved since the introduction of the package and a minimum subsidy, but village doctors do not find the subsidy to be sufficient remuneration for their efforts. LESSONS LEARNT: Improving the delivery of public health services by village doctors is likely to require an increase in the subsidy, improvement in the supervisory relationship between village clinics and township health centres and the creation of a government pension for village doctors.

Résumé PROBLÈME: Le gouvernement central chinois a lancé le plan de réforme du système de santé en 2009 pour renforcer la lutte contre les maladies et l'amélioration de la santé, et pour fournir un paquet de services de base en termes de santé publique. Les médecins de village reçoivent une subvention modeste pour offrir des services de santé publique liés à ce paquet. Leurs opinions sur cette subvention et la fourniture de services de santé publique pourraient avoir une influence sur la qualité et l'efficacité des services de santé préventive et sur la surveillance des maladies. APPROCHE: Pour comprendre les perspectives des médecins de village sur la subvention et leur expérience dans le domaine de la fourniture de services de santé publique, nous avons organisé 10 discussions de groupe cible avec des médecins de village, 12 entrevues approfondies avec des directeurs de centres de santé cantonaux et 4 entrevues approfondies avec des directeurs départementaux de centres pour la lutte et la prévention des maladies. ENVIRONNEMENT LOCAL: L'étude a été effectuée dans quatre comtés du centre de la Chine, deux dans la province de Hubei et deux dans la province du Jiangxi. CHANGEMENTS SIGNIFICATIFS: Les médecins de village donnent la priorité aux services médicaux, mais ils font de leur mieux pour gérer leur temps de manière à inclure les services de santé publique. La volonté des directeurs de centres de santé cantonaux et des médecins de village d'offrir des services de santé publique s'est accrue depuis l'introduction du paquet et d'une subvention minimale, mais les médecins de village ne considèrent pas que cette subvention constitue une rémunération suffisante pour leurs efforts. LEÇONS TIRÉES: Il est possible que l'amélioration de la fourniture de services de santé publique par les médecins de village nécessite une augmentation de la subvention, l'amélioration de la relation de supervision entre cliniques de village et centres de santé cantonaux et la création d'une pension gouvernementale pour les médecins de village.

Resumen SITUACIÓN: En el año 2009, el gobierno central chino puso en marcha el plan de reforma del sistema sanitario con el objetivo de reforzar el control de las enfermedades y fomentar la salud, así como proporcionar un paquete de servicios básicos de salud pública. Los médicos rurales perciben una modesta subvención por la prestación de los servicios de salud pública relacionados con dicho paquete. Sus opiniones acerca de dicha subvención y la prestación de los servicios de salud pública podrían influir en la calidad y la eficacia de los servicios sanitarios preventivos y de la vigilancia de las enfermedades. ENFOQUE: Con objeto de comprender los puntos de vista de los médicos rurales acerca de la subvención y sus experiencias en la prestación de servicios sanitarios, hemos llevado a cabo 10 debates con grupos focales de médicos rurales, 12 entrevistas en detalle con directores de centros de salud municipales y 4 entrevistas en detalle con directores de Centros para el Control y Prevención de las Enfermedades provinciales. MARCO REGIONAL: El estudio se llevó a cabo en cuatro condados del centro de China, dos de ellos en la provincia de Hubei y otros dos en la de Jiangxi. CAMBIOS IMPORTANTES: Los médicos rurales dan prioridad a los servicios médicos, pero hacen todo lo posible por gestionar su tiempo a fin de incluir los servicios de salud pública. La disposición de los directores de los centros sanitarios municipales y de los médicos rurales para prestar los servicios de salud pública ha aumentado desde la introducción del paquete y de la subvención mínima, si bien los médicos rurales no consideran que sea una retribución suficiente por sus esfuerzos. LECCIONES APRENDIDAS: Es probable que, para mejorar la prestación de servicios de salud pública por parte de los médicos rurales, sea necesario un aumento de la subvención, una mejora en la relación de supervisión entre las clínicas rurales y los centros de salud municipales, así como la creación de una pensión gubernamental para los médicos rurales.

Barriers and facilitators to the implementation of lay health worker programmes to improve access to maternal and child health: qualitative evidence synthesis.

BACKGROUND: Lay health workers (LHWs) perform functions related to healthcare delivery, receive some level of training, but have no formal professional or paraprofessional certificate or tertiary education degree. They provide care for a range of issues, including maternal and child health. For LHW programmes to be effective, we need a better understanding of the factors that influence their success and sustainability. This review addresses these issues through a synthesis of qualitative evidence and was carried out alongside the Cochrane review of the effectiveness of LHWs for maternal and child health. OBJECTIVES: The overall aim of the review is to explore factors affecting the implementation of LHW programmes for maternal and child health. SEARCH METHODS: We searched MEDLINE, OvidSP (searched 21 December 2011); MEDLINE Ovid In-Process & Other Non-Indexed Citations, OvidSP (searched 21 December 2011); CINAHL, EBSCO (searched 21 December 2011); British Nursing Index and Archive, OvidSP (searched 13 May 2011). We searched reference lists of included studies, contacted experts in the field, and included studies that were carried out alongside the trials from the LHW effectiveness review. SELECTION CRITERIA: Studies that used qualitative methods for data collection and analysis and that focused on the experiences and attitudes of stakeholders regarding LHW programmes for maternal or child health in a primary or community healthcare setting. DATA COLLECTION AND ANALYSIS: We identified barriers and facilitators to LHW programme implementation using the framework thematic synthesis approach. Two review authors independently assessed study quality using a standard tool. We assessed the certainty of the review findings using the CerQual approach, an approach that we developed alongside this and related qualitative syntheses. We integrated our findings with the outcome measures included in the review of LHW programme effectiveness in a logic model. Finally, we identified hypotheses for subgroup analyses in future updates of the review of effectiveness. MAIN RESULTS: We included 53 studies primarily describing the experiences of LHWs, programme recipients, and other health workers. LHWs in high income countries mainly offered promotion, counselling and support. In low and middle income countries, LHWs offered similar services but sometimes also distributed supplements, contraceptives and other products, and diagnosed and treated children with common childhood diseases. Some LHWs were trained to manage uncomplicated labour and to refer women with pregnancy or labour complications.Many of the findings were based on studies from multiple settings, but with some methodological limitations. These findings were assessed as being of moderate certainty. Some findings were based on one or two studies and had some methodological limitations. These were assessed have low certainty.Barriers and facilitators were mainly tied to programme acceptability, appropriateness and credibility; and health system constraints. Programme recipients were generally positive to the programmes, appreciating the LHWs' skills and the similarities they saw between themselves and the LHWs. However, some recipients were concerned about confidentiality when receiving home visits. Others saw LHW services as not relevant or not sufficient, particularly when LHWs only offered promotional services. LHWs and recipients emphasised the importance of trust, respect, kindness and empathy. However, LHWs sometimes found it difficult to manage emotional relationships and boundaries with recipients. Some LHWs feared blame if care was not successful. Others felt demotivated when their services were not appreciated. Support from health systems and community leaders could give LHWs credibility, at least if the health systems and community leaders had authority and respect. Active support from family members was also important.Health professionals often appreciated the LHWs' contributions in reducing their workload and for their communication skills and commitment. However, some health professionals thought that LHWs added to their workload and feared a loss of authority.LHWs were motivated by factors including altruism, social recognition, knowledge gain and career development. Some unsalaried LHWs wanted regular payment, while others were concerned that payment might threaten their social status or lead recipients to question their motives. Some salaried LHWs were dissatisfied with their pay levels. Others were frustrated when payment differed across regions or institutions. Some LHWs stated that they had few opportunities to voice complaints. LHWs described insufficient, poor quality, irrelevant and inflexible training programmes, calling for more training in counselling and communication and in topics outside their current role, including common health problems and domestic problems. LHWs and supervisors complained about supervisors' lack of skills, time and transportation. Some LHWs appreciated the opportunity to share experiences with fellow LHWs.In some studies, LHWs were traditional birth attendants who had received additional training. Some health professionals were concerned that these LHWs were over-confident about their ability to manage danger signs. LHWs and recipients pointed to other problems, including women's reluctance to be referred after bad experiences with health professionals, fear of caesarean sections, lack of transport, and cost. Some LHWs were reluctant to refer women on because of poor co-operation with health professionals.We organised these findings and the outcome measures included in the review of LHW programme effectiveness in a logic model. Here we proposed six chains of events where specific programme components lead to specific intermediate or long-term outcomes, and where specific moderators positively or negatively affect this process. We suggest how future updates of the LHW effectiveness review could explore whether the presence of these components influences programme success. AUTHORS' CONCLUSIONS: Rather than being seen as a lesser trained health worker, LHWs may represent a different and sometimes preferred type of health worker. The close relationship between LHWs and recipients is a programme strength. However, programme planners must consider how to achieve the benefits of closeness while minimizing the potential drawbacks. Other important facilitators may include the development of services that recipients perceive as relevant; regular and visible support from the health system and the community; and appropriate training, supervision and incentives.

Developing lay health worker policy in South Africa: a qualitative study.

BACKGROUND: Over the past half decade South Africa has been developing, implementing and redeveloping its Lay Health Worker (LHW) policies. Research during this period has highlighted challenges with LHW programme implementation. These challenges have included an increased burden of care for female LHWs. The aim of this study was to explore contemporary LHW policy development processes and the extent to which issues of gender are taken up within this process. METHODS: The study adopted a qualitative approach to exploring policy development from the perspective of policy actors. Eleven policy actors (policy makers and policy commentators) were interviewed individually. Data from the interviews were analysed thematically. RESULTS: Considerations of LHW working conditions drove policy redevelopment. From the interviews it seems that gender as an issue never reached the policy making agenda. Although there was strong recognition that the working conditions of LHWs needed to be improved, poor working conditions were not necessarily seen as a gender concern. Our data suggests that in the process of defining the problem which the redeveloped policy had to address, gender was not included. There was no group or body who brought the issue of gender to the attention of policy developers. As such the issue of gender never entered the policy debates. These debates focused on whether it was appropriate to have LHWs, what LHW programme model should be adopted and whether or not LHWs should be incorporated into the formal health system. CONCLUSION: LHW policy redevelopment focused on resolving issues of LHW working conditions through an active process involving many actors and strong debates. Within this process the issue of gender had no champion and never reached the LHW policy agenda. Future research may consider how to incorporate the voices of ordinary women into the policy making process.

Health worker recruitment and deployment in remote areas of Indonesia.

CONTEXT: Providing health care in remote and very remote areas has long been a major concern in Indonesia. In order to improve access to quality health care for residents in these areas, various policies on recruitment and deployment of health workers have been implemented, among them compulsory service, contracted staff and the Special Assignment of strategic health workers. ISSUE: Indonesia's difficult geography presents great challenges to health service delivery and most health workers prefer to serve in urban areas, resulting in an uneven distribution of health workers and shortages in remote areas. Great efforts have been made to mobilize health human resources more equitably, including placement schemes for strategic health workers and contracted staff, combined with an incentive scheme. While these have partially addressed the severe shortage of health workers in remote areas, current government policies were reviewed in order to clarify the current situation in Indonesia. LESSONS LEARNED: The Contracted Staff and Special Assignment of Strategic Health Workers programs show have made a significant contribution to improving the availability of health workers in Indonesia's remote areas. As these two programs used financial incentives as the main intervention, other non-financial interventions should also be trialed. For example, incentives such as the promise of a civil servant appointment or the provision of continuing professional education, as well as the recruitment of rural-background health workers may increase the willingness of health staff to serve in the remote and very remote areas of Indonesia.

A qualitative exploration of barriers to health-facility-based delivery in Bomachoge-Borabu and Kaloleni, Kenya.

OBJECTIVE: To explore barriers to utilization of health-facility-based delivery in Kenya, use of which is associated with reduced maternal mortality. METHODS: In April 2017, a qualitative study utilizing key informant interviews (KIIs) and focus group discussions (FGDs) was carried out in Bomachoge-Borabu and Kaloleni, Kenya. Twenty-four KIIs were performed including health service providers, community health workers, religious leaders, local government representatives, Ministry of Health representatives, and representatives of women's organizations. Sixteen FGDs were held separately with adolescent females, adult females, adult males, and Community Health Committee members. Data were transcribed, coded, and categorized thematically to illustrate supply-side and demand-side barriers to use of health-facility-based delivery services. RESULTS: Supply-side barriers included staff shortages, inadequate supplies and space, poor interpersonal relations, few trained staff, long distance to services, poor transport infrastructure, and limited service hours. Demand-side barriers included financial constraints, limited spousal support, observance of birthing traditions, limited knowledge on importance of health-facility-based delivery, and fear of health-facility procedures. CONCLUSIONS: Diverse barriers continue to influence use of health-facility-based delivery services in Kenya. Practical, integrated interventions are urgently needed to reduce barriers noted, to further reduce the maternal mortality rate.

Assessing the quality of service of village malaria workers to strengthen community-based malaria control in Cambodia.

BACKGROUND: Malaria continues to be a major public health problem in remote forested areas in Cambodia. As a national strategy to strengthen community-based malaria control, the Cambodian government has been running the Village Malaria Worker (VMW) project since 2001. This study sought to examine the nature and quality of the VMWs' services. METHODS: Data collection was carried out in February and March 2008 through interviews with one of the two VMWs who takes the lead in malaria control activities in each of the 315 VMW villages (n = 251). The questionnaire addressed 1) the sociodemographic characteristics of VMWs, 2) service quality, 3) actions for malaria prevention and vector control, and 4) knowledge of malaria epidemiology and vector ecology. RESULTS: VMWs were effective in conducting diagnosis with Rapid Diagnostic Tests (RDTs) and prescribing anti-malarials to those who had positive RDT results, skills that they had acquired through their training programmes. However, most other services, such as active detection, explanations about compliance, and follow-up of patients, were carried out by only a small proportion of VMWs. The variety of actions that VMWs took for malaria prevention and vector control was small (average action index score 12.8/23), and their knowledge was very limited with less than 20% of the VMWs giving correct answers to six out of seven questions on malaria epidemiology and vector ecology. Knowledge of vector breeding places and malaria transmission were significant determinants of both the quality of VMWs' services and the variety of their actions for malaria prevention and vector control. CONCLUSIONS: VMWs' services focused primarily on diagnosis and treatment. Their focus needs to be broadened to cover other aspects of malaria control in order to further strengthen community-based malaria control. VMWs' actions and knowledge also need substantial improvement. Strengthening training programmes can help achieve better performance by VMWs.

Lay health workers and HIV programmes: implications for health systems.

One of the consequences of massive investment in antiretroviral access and other AIDS programmes has been the rapid emergence of large numbers of lay workers in the health systems of developing countries. In South Africa, government estimates are 65,000, mostly HIV/TB care-related lay workers contribute their labour in the public health sector, outnumbering the main front-line primary health care providers and professional nurses. The phenomenon has grown organically and incrementally, playing a wide variety of care-giving, support and advocacy roles. Using South Africa as a case, this paper discusses the different forms, traditions and contradictory orientations taken by lay health work and the system-wide effects of a large lay worker presence. As pressures to regularise and formalize the status of lay health workers grow, important questions are raised as to their place in health systems, and more broadly what they represent as a new intermediary layer between state and citizen. It argues for a research agenda that seeks to better characterise types of lay involvement in the health system, particularly in an era of antiretroviral therapy, and which takes a wider perspective on the meanings of this recent re-emergence of an old concept in health systems heavily affected by HIV/AIDS.

A realist synthesis of randomised control trials involving use of community health workers for delivering child health interventions in low and middle income countries.

BACKGROUND: A key constraint to saturating coverage of interventions for reducing the burden of childhood illnesses in Low and Middle Income Countries (LMIC) is the lack of human resources. Community health workers (CHW) are potentially important actors in bridging this gap. Evidence exists on effectiveness of CHW in management of some childhood illnesses (IMCI). However, we need to know how and when this comes to be. We examine evidence from randomized control trials (RCT) on CHW interventions in IMCI in LMIC from a realist perspective with the aim to see if they can yield insight into the working of the interventions, when examined from a different perspective. METHODS: The realist approach involves educing the mechanisms through which an intervention produced an outcome in a particular context. 'Mechanisms' are reactions, triggered by the interaction of the intervention and a certain context, which lead to change. These are often only implicit and are actually hypothesized by the reviewer. This review is limited to unravelling these from the RCTs; it is thus a hypothesis generating exercise. RESULTS: Interventions to improve CHW performance included 'Skills based training of CHW', 'Supervision and referral support from public health services', 'Positioning of CHW in the community'. When interventions were applied in context of CHW programs embedded in local health services, with beneficiaries who valued services and had unmet needs, the interventions worked if following mechanisms were triggered: anticipation of being valued by the community; perception of improvement in social status; sense of relatedness with beneficiaries and public services; increase in self esteem; sense of self efficacy and enactive mastery of tasks; sense of credibility, legitimacy and assurance that there was a system for back-up support. Studies also showed that if context differed, even with similar interventions, negative mechanisms could be triggered, compromising CHW performance. CONCLUSION: The aim of this review was to explore if RCTs could yield insight into the working of the interventions, when examined from a different, a realist perspective. We found that RCTs did yield some insight, but the hypotheses generated were very general and not well refined. These hypotheses need to be tested and refined in further studies.

Community health workers for non-communicable diseases prevention and control in Bangladesh: a qualitative study.

BACKGROUND: The increasing burden of Non-Communicable Diseases (NCDs) in Bangladesh underscores the importance of strengthening primary health care systems. In this study, we examined the barriers and facilitators to engaging Community Health Workers (CHWs) for NCDs prevention and control in Bangladesh. METHODS: We used multipronged approaches, including a. Situation analyses using a literature review, key personnel and stakeholders' consultative meetings, and exploratory studies. A grounded theory approach was used for qualitative data collection from health facilities across three districts in Bangladesh. We conducted in-depth interviews with CHWs (Health Inspector; Community Health Care Provider; Health Assistant and Health Supervisor) (n = 4); key informant interviews with central level health policymakers/ managers (n = 15) and focus group discussions with CHWs (4 FGDs; total n = 29). Participants in a stakeholder consultative meeting included members from the government (n = 4), non-government organisations (n = 2), private sector (n = 1) and universities (n = 2). Coding of the qualitative data and identification of themes from the transcripts were carried out and thematic approach was used for data analyses. RESULTS: The CHWs in Bangladesh deliver a wide range of public health programs. They also provide several NCDs specific services, including screening, provisional diagnosis, and health education and counselling for common NCDs, dispensing basic medications, and referral to relevant health facilities. These services are being delivered from the sub-district health facility, community clinics and urban health clinics. The participants identified key challenges and barriers, which include lack of NCD specific guidelines, inadequate training, excessive workload, inadequate systems-level support, and lack of logistics supplies and drugs. Yet, the facilitating factors to engaging CHWs included government commitment and program priority, development of NCD related policies and strategies, establishment of NCD corners, community support systems, social recognition of health care staff and their motivation. CONCLUSION: Engaging CHWs has been a key driver to NCDs services delivery in Bangladesh. However, there is a need for building capacity of CHWs, maximizing CHWs engagement to NCD services delivery, facilitating systems-level support and strengthening partnerships with non-state sectors would be effective in prevention and control efforts of NCDs in Bangladesh.

Community-Based Interventions for Stroke Provided by Nurses and Community Health Workers: A Review of the Literature.

BACKGROUND: Community-based interventions are vital for facilitating poststroke recovery, increasing community participation, and raising awareness about stroke survivors. To optimize recovery and community reintegration, there is a need to understand research findings on community-based interventions that focus on stroke survivors and their caregivers. Although nurses and community health workers (CHWs) are commonly involved in community-based interventions, less is known about their roles relative to other poststroke rehabilitation professionals (physical therapists, occupational therapists, and speech-language pathologists). Thus, the purpose of this review is to explore research focused on improving community-based stroke recovery for adult stroke survivors, caregivers, or both when delivered by nurses or CHWs. METHODS: A systematic review using Scopus, PubMed, EBSCOhost, MEDLINE, CINAHL Complete, and PsycInfo was completed to identify community-based poststroke intervention studies using nurses or CHWs through August 2018. RESULTS: Eighteen studies meeting inclusion criteria from 9 countries were identified. Details regarding nurses' and CHWs' roles were limited or not discussed. Interventions emphasized stroke survivor self-care and caregiver support and were offered face-to-face and in group sessions in the community and home. A wide range of instruments were used to measure outcomes. The results of the interventions provided were mixed. Improvements were observed in perceptions of health, quality of life, knowledge, self-efficacy, self-management, and caregiver support. CONCLUSION: Nurses and CHWs play a pivotal role in community-based care. Evidence suggests community-based interventions facilitate the necessary support for stroke survivors, caregivers, families, and communities to optimize stroke recovery. Data from this review illustrate a continued need for comprehensive programs designed to address the complex needs of stroke survivors and families when they return to their homes and communities.
