What do we know about community-based health worker programs? A systematic review of existing reviews on community health workers.

OBJECTIVE: To synthesize current understanding of how community-based health worker (CHW) programs can best be designed and operated in health systems. METHODS: We searched 11 databases for review articles published between 1 January 2005 and 15 June 2017. Review articles on CHWs, defined as non-professional paid or volunteer health workers based in communities, with less than 2 years of training, were included. We assessed the methodological quality of the reviews according to AMSTAR criteria, and we report our findings based on PRISMA standards. FINDINGS: We identified 122 reviews (75 systematic reviews, of which 34 are meta-analyses, and 47 non-systematic reviews). Eighty-three of the included reviews were from low- and middle-income countries, 29 were from high-income countries, and 10 were global. CHW programs included in these reviews are diverse in interventions provided, selection and training of CHWs, supervision, remuneration, and integration into the health system. Features that enable positive CHW program outcomes include community embeddedness (whereby community members have a sense of ownership of the program and positive relationships with the CHW), supportive supervision, continuous education, and adequate logistical support and supplies. Effective integration of CHW programs into health systems can bolster program sustainability and credibility, clarify CHW roles, and foster collaboration between CHWs and higher-level health system actors. We found gaps in the review evidence, including on the rights and needs of CHWs, on effective approaches to training and supervision, on CHWs as community change agents, and on the influence of health system decentralization, social accountability, and governance. CONCLUSION: Evidence concerning CHW program effectiveness can help policymakers identify a range of options to consider. However, this evidence needs to be contextualized and adapted in different contexts to inform policy and practice. Advancing the evidence base with context-specific elements will be vital to helping these programs achieve their full potential.

Financial interventions and movement restrictions for managing the movement of health workers between public and private organizations in low- and middle-income countries.

BACKGROUND: Health workers move between public and private organizations in both urban and rural areas during the course of their career. Depending on the proportion of the population served by public or private organizations in a particular setting, this movement may result in imbalances in the number of healthcare providers available relative to the population receiving care from that sector. However, both public and private organizations are needed as each sector has unique contributions to make to the effective delivery of health services. OBJECTIVES: To assess the effects of financial incentives and movement restriction interventions to manage the movement of health workers between public and private organizations in low- and middle-income countries. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (10 November 2012); EMBASE (7 June 2011); LILACS (9 June 2011); MEDLINE (10 November 2012); CINAHL (13 August 2012); and the British Nursing Index (13 August 2012). SELECTION CRITERIA: Randomized controlled trials and non-randomized controlled trials; controlled before-and-after studies if pre- and post-intervention periods for study and control groups were the same and there were at least two units included in both the intervention and control groups; uncontrolled and controlled interrupted time series studies if the point in time when the intervention occurred was clearly defined and there were at least three or more data points before and after the intervention. Interventions included payment of special allowances, increasing salaries, bonding health workers, offering bursary schemes, scholarships or lucrative terminal benefits, and hiring people on contract basis. DATA COLLECTION AND ANALYSIS: Two review authors independently applied the criteria for inclusion and exclusion of studies to the titles and abstracts of all articles obtained from the search. The same two review authors independently screened the full reports of the selected citations. At each stage, we compared the results and resolved discrepancies through discussion with a third review author. MAIN RESULTS: We found no studies that were eligible for inclusion in this review. AUTHORS' CONCLUSIONS: We identified no rigorous studies on the effects of interventions to manage the movement of health workers between public and private organizations in low- and middle-income countries. Health worker availability is a key obstacle in delivery of health services. Interventions to make the health sector more responsive to the expectations of populations by having more health workers in the sector that serves most people would contribute to the more efficient use of the health workforce. More research is needed to assess the effect of increase in salaries, offering scholarships or bonding on movement of health workers in one sector compared with another.

Interventions to manage dual practice among health workers.

BACKGROUND: Dual practice, whereby health workers hold two or more jobs, is a common phenomenon globally. In resource constrained low- and middle-income countries dual practice poses an ongoing threat to the efficiency, quality and equity of health services, especially in the public sector. Identifying effective interventions to manage dual practice is important. OBJECTIVES: To assess the effects of regulations implemented to manage dual practice. SEARCH STRATEGY: Databases searched included: The Cochrane Central Register of Controlled Trials (CENTRAL) 2011, Issue 4, part of The Cochrane Library. www.thecochranelibrary.com, including the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (searched 26 May 2011); MEDLINE In-Process & Other Non-Indexed Citations May 24, 2011 (searched 26 May 2011); MEDLINE, Ovid (1948 to May week 2 2011) (searched 26 May 2011); EMBASE, Ovid (1980 to 2011 week 20) (searched 26 May 2011); Science Citation Index and Social Sciences Citation Index, ISI Web of Science (1975 to present) (searched 04 December 2009); LILACS (searched January 2010); and AIM (December 2009) (searched 18 December 2009). SELECTION CRITERIA: Randomized controlled trials, non-randomized controlled trials, controlled before-and-after studies and interrupted-time-series studies. Dual practice was defined as holding more than one job. Studies for inclusion were those focusing on interventions to manage dual practice among health professionals employed in the public health sector. DATA COLLECTION AND ANALYSIS: Two review authors independently applied the criteria for inclusion and exclusion of studies when scanning the identified titles and abstracts. The same two review authors independently screened full reports of selected citations. At each stage, results were compared and discrepancies settled through discussion. MAIN RESULTS: No studies were found which were eligible for inclusion in this review. AUTHORS' CONCLUSIONS: There is a need to rigorously evaluate the effects of interventions implemented to manage dual practice among health workers. However, there is still much that is unknown about dual practice itself. The designing of studies to evaluate the effects of interventions to manage dual practice could benefit from prior studies to assess the various manifestations of dual practice, their prevalence and their likely impacts on health services delivery. These findings would then inform the design of studies to evaluate interventions to manage dual practice.

Field Epidemiology Training Programmes in Africa - Where are the Graduates?

BACKGROUND: The current shortage of human resources for health threatens the attainment of the Millennium Development Goals. There is currently limited published evidence of health-related training programmes in Africa that have produced graduates, who remain and work in their countries after graduation. However, anecdotal evidence suggests that the majority of graduates of field epidemiology training programmes (FETPs) in Africa stay on to work in their home countries--many as valuable resources to overstretched health systems. METHODS: Alumni data from African FETPs were reviewed in order to establish graduate retention. Retention was defined as a graduate staying and working in their home country for at least 3 years after graduation. African FETPs are located in Burkina Faso, Ethiopia, Ghana, Kenya, Nigeria, Rwanda, South Africa, the United Republic of Tanzania, Uganda and Zimbabwe. However, this paper only includes the Uganda and Zimbabwe FETPs, as all the others are recent programmes. RESULTS: This review shows that enrolment increased over the years, and that there is high graduate retention, with 85.1% (223/261) of graduates working within country of training; most working with Ministries of Health (46.2%; 105/261) and non-governmental organizations (17.5%; 40/261). Retention of graduates with a medical undergraduate degree was higher (Zimbabwe 80% [36/83]; Uganda 90.6% [125/178]) than for those with other undergraduate qualifications (Zimbabwe 71.1% [27/83]; Uganda 87.5% [35/178]). CONCLUSIONS: African FETPs have unique features which may explain their high retention of graduates. These include: programme ownership by ministries of health and local universities; well defined career paths; competence-based training coupled with a focus on field practice during training; awarding degrees upon completion; extensive training and research opportunities made available to graduates; and the social capital acquired during training.

Implementation of global health competencies: A scoping review on target audiences, levels, and pedagogy and assessment strategies.

BACKGROUND: As the field of global health expands, the recognition of structured training for field-based public health professionals has grown. Substantial effort has gone towards defining competency domains for public health professionals working globally. However, there is limited literature on how to implement competency-based training into learning curricula and evaluation strategies. OBJECTIVES: This scoping review seeks to collate the current status, degree of consensus, and best practices, as well as gaps and areas of divergence, related to the implementation of competencies in global health curricula. Specifically, we sought to examine (i) the target audience, (ii) the levels or milestones, and (iii) the pedagogy and assessment approaches. SOURCES OF EVIDENCE: A review of the published and grey literature was completed to identify published and grey literature sources that presented information on how to implement or support global health and public health competency-based education programs. In particular, we sought to capture any attempts to assign levels or milestones, any evaluation strategies, and the different pedagogical approaches. RESULTS: Out of 68 documents reviewed, 21 documents were included which contained data related to the implementation of competency-based training programs; of these, 18 were peer-reviewed and three were from the grey literature. Most of the sources focused on post-graduate public health students, professional trainees pursuing continuing education training, and clinical and allied health professionals working in global health. Two approaches were identified to defining skill level or milestones, namely: (i) defining levels of increasing ability or (ii) changing roles across career stages. Pedagogical approaches featured field experience, direct engagement, group work, and self-reflection. Assessment approaches included self-assessment surveys, evaluations by peers and supervisors, and mixed methods assessments. CONCLUSIONS: The implementation of global health competencies needs to respond to the needs of specific agencies or particular groups of learners. A milestones approach may aide these efforts while also support monitoring and evaluation. Further development is needed to understand how to assess competencies in a consistent and relevant manner.

Community health workers for ART in sub-Saharan Africa: learning from experience--capitalizing on new opportunities.

Low-income countries with high HIV/AIDS burdens in sub-Saharan Africa must deal with severe shortages of qualified human resources for health. This situation has triggered the renewed interest in community health workers, as they may play an important role in scaling-up antiretroviral treatment for HIV/AIDS by taking over a number of tasks from the professional health workers. Currently, a wide variety of community health workers are active in many antiretroviral treatment delivery sites. This article investigates whether present community health worker programmes for antiretroviral treatment are taking into account the lessons learnt from past experiences with community health worker programmes in primary health care and to what extent they are seizing the new antiretroviral treatment-specific opportunities. Based on a desk review of multi-purpose community health worker programmes for primary health care and of recent experiences with antiretroviral treatment-related community health workers, we developed an analytic framework of 10 criteria: eight conditions for successful large-scale antiretroviral treatment-related community health worker programmes and two antiretroviral treatment-specific opportunities. Our appraisal of six community health worker programmes, which we identified during field work in Ethiopia, Malawi and Uganda in 2007, shows that while some lessons from the past have been learnt, others are not being sufficiently considered and antiretroviral treatment-specific opportunities are not being sufficiently seized.In particular, all programmes have learnt the lesson that without adequate remuneration, community health workers cannot be retained in the long term. Yet we contend that the apparently insufficient attention to issues such as quality supervision and continuous training will lead to decreasing quality of the programmes over time. The life experience of people living with HIV/AIDS is still a relatively neglected asset, even though it may give antiretroviral treatment-related community health worker programmes better chances of success than their predecessors and may be crucially important for adherence and retention in large-scale antiretroviral treatment programmes. Community health workers as a community-based extension of health services are essential for antiretroviral treatment scale-up and comprehensive primary health care. The renewed attention to community health workers is thus very welcome, but the scale-up of community health worker programmes runs a high risk of neglecting the necessary quality criteria if it is not aligned with broader health systems strengthening. To achieve universal access to antiretroviral treatment, this is of paramount importance and should receive urgent attention.

Digital Technologies for Health Workforce Development in Low- and Middle-Income Countries: A Scoping Review.

The collection of journal articles, systematic reviews, and reports published over the last decade that attest to the potential of digital technologies to achieve health workforce improvements across all aspects of the health system is vast. As a capacity-building mechanism, digital technology has potential for low- and middle-income countries (LMICs) to support development of the health workforce, including those health workers based in remote or rural areas, to train, motivate, support, monitor, and pay them. The purpose of this scoping review to present, at a high level, the state of the evidence and best practices in digital strategies for human resources for health and to propose a roadmap for a research agenda to fill identified gaps in the evidence. A variety of peer-reviewed and gray literature sources were searched using selected key terms related to digital health and health workforce, limited to materials published from 2010 to 2018. More than 70 articles, reports, and blog posts were reviewed, with in-depth analysis of 29 articles. Findings show that a range of digital health solutions for health workforce development have been tested and used, such as for health worker training, provider-to-provider communication and professional networking, and supervision of and performance feedback to health workers. There is some evidence of improved efficiency and effectiveness, at least at the level of pilots or small-scale projects. There is, however, a growing urgency in global health to move beyond small-scale demonstration projects and to define the capital and recurring costs of implementation and scale up of digital health interventions, including the return on investment. The next frontier is to select, adapt, and implement at scale those digital health interventions for health worker development and management found to be most promising.

Assessing the performance of medical personnel involved in the diagnostic imaging processes in mulago hospital, kampala, Uganda.

OBJECTIVES: Uganda, has limited health resources and improving performance of personnel involved in imaging is necessary for efficiency. The objectives of the study were to develop and pilot imaging user performance indices, document non-tangible aspects of performance, and propose ways of improving performance. MATERIALS AND METHODS: This was a cross-sectional survey employing triangulation methodology, conducted in Mulago National Referral Hospital over a period of 3 years from 2005 to 2008. The qualitative study used in-depth interviews, focus group discussions, and self-administered questionnaires, to explore clinicians' and radiologists' performancerelated views. RESULTS: THE STUDY CAME UP WITH FOLLOWING INDICES: appropriate service utilization (ASU), appropriateness of clinician's nonimaging decisions (ANID), and clinical utilization of imaging results (CUI). The ASU, ANID, and CUI were: 94%, 80%, and 97%, respectively. The clinician's requisitioning validity was high (positive likelihood ratio of 10.6) contrasting with a poor validity for detecting those patients not needing imaging (negative likelihood ratio of 0.16). Some requisitions were inappropriate and some requisition and reports lacked detail, clarity, and precision. CONCLUSION: Clinicians perform well at imaging requisition-decisions but there are issues in imaging requisitioning and reporting that need to be addressed to improve performance.

Mid-level health providers: a promising resource.

Mid-level health providers (MLP) are health workers trained at a higher education institution for at least a total of 2-3 years, and authorized and regulated to work autonomously to diagnose, manage and treat illness, disease and impairments, as well as engage in preventive and promotive care. Their role has been progressively expanding and receiving attention, in particular in low- and middle-income countries, as a strategy to overcome health workforce challenges and improve access to essential health services and achieve the health related targets of the Millennium Development Goals. Evidence, although limited and imperfect, shows that, where MLP are adequately trained, supported and integrated coherently in the health system, they have the potential to improve distribution of health workers and enhance equitable access to health services, while retaining quality standards comparable to, if not exceeding, those of services provided by physicians. Significant challenges however exist in terms of the marginalization and more limited management support of MLP in health systems. The expansion of MLP should have priority among the policy options considered by countries facing shortage and maldistribution challenges. Improved education, supervision, management and regulation practices and integration in the health system have the potential to maximize the benefits from the use of these cadres.

Trabajadores de salud de nivel intermedio: un recurso prometedor / Mid-level health providers: a promising resource

Los trabajadores de salud de nivel intermedio (TSNI) son trabajadores capacitados en una institución de educación superior durante al menos dos a tres años, quienes son autorizados y regulados para trabajar de forma autónoma para el diagnóstico, control y tratamiento de dolencias, enfermedades y discapacidades, así como participar en la prevención y promoción de la salud. Su papel se ha ampliado progresivamente y ha recibido atención en particular en países de ingresos bajos y medios, como parte de una estrategia para superar los desafíos del personal sanitario, mejorar el acceso a servicios básicos de salud y lograr objetivos relacionados con los Objetivos del Desarrollo del Milenio. La evidencia, aunque limitada e imperfecta, muestra que donde los TSNI están debidamente capacitados, apoyados y coherentemente integrados en el sistema de salud, tienen el potencial para mejorar la distribución de los trabajadores de la salud y el acceso equitativo a los servicios de salud, manteniendo -si no sobrepasando- los estándares de calidad comparables a los servicios prestados por el personal médico. Sin embargo, existen desafíos importantes en términos de la marginación y el limitado apoyo a la gestión de los TSNI en los sistemas de salud. La expansión de los TSNI debe tener prioridad entre las opciones de política consideradas por países que enfrentan problemas de escasez y desigualdad en la distribución de recursos humanos. Una mejor educación, supervisión, administración y regulación de las prácticas y la integración en el sistema de salud tienen el potencial de maximizar los beneficios de la utilización de este personal.

Improving facility-based care for sick children in Uganda: training is not enough.

This study assessed the effects of scaling-up Integrated Management of Childhood Illness (IMCI) on the quality of care received by sick children in 10 districts in Uganda. Health workers trained in IMCI were found to deliver significantly better care than health workers who had not yet been trained, but absolute levels of service quality remained low. Achieving training coverage alone is not sufficient as a strategy to improve and sustain care quality. Other factors including training quality, effective supervision, availability of essential drugs, vaccines and equipment, and the policy context are also important and must be included in child survival policies and plans.
