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

<p>Abstract</p> <p>Background</p> <p>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.</p> <p>Methods</p> <p>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.</p> <p>Results</p> <p>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.</p> <p>Conclusion</p> <p>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.</p

Human resource management interventions to improve health workers' performance in low and middle income countries: a realist review

Contains fulltext : 80429.pdf (publisher's version ) (Open Access)BACKGROUND: Improving health workers' performance is vital for achieving the Millennium Development Goals. In the literature on human resource management (HRM) interventions to improve health workers' performance in Low and Middle Income Countries (LMIC), hardly any attention has been paid to the question how HRM interventions might bring about outcomes and in which contexts. Such information is, however, critical to assess the transferability of results. Our aim was to explore if realist review of published primary research provides better insight into the functioning of HRM interventions in LMIC. METHODOLOGY: A realist review not only asks whether an intervention has shown to be effective, but also through which mechanisms an intervention produces outcomes and which contextual factors appear to be of critical influence. Forty-eight published studies were reviewed. Results : The results show that HRM interventions can improve health workers' performance, but that different contexts produce different outcomes. Critical implementation aspects were involvement of local authorities, communities and management; adaptation to the local situation; and active involvement of local staff to identify and implement solutions to problems. Mechanisms that triggered change were increased knowledge and skills, feeling obliged to change and health workers' motivation. Mechanisms to contribute to motivation were health workers' awareness of local problems and staff empowerment, gaining acceptance of new information and creating a sense of belonging and respect. In addition, staff was motivated by visible improvements in quality of care and salary supplements. Only a limited variety of HRM interventions have been evaluated in the health sector in LMIC. Assumptions underlying HRM interventions are usually not made explicit, hampering our understanding of how HRM interventions work. CONCLUSION: Application of a realist perspective allows identifying which HRM interventions might improve performance, under which circumstances, and for which groups of health workers. To be better able to contribute to an understanding of how HRM interventions could improve health workers' performance, a combination of qualitative and quantitative research methods would be needed and the use of common indicators for evaluation and a common reporting format would be required

Health provider responsiveness to social accountability initiatives in low- and middle-income countries: A realist review

Social accountability in the health sector has been promoted as a strategy to improve the quality and performance of health providers in low- and middle-income countries. Whether improvements occur, however, depends on the willingness and ability of health providers to respond to societal pressure for better care. This article uses a realist approach to review cases of collective citizen action and advocacy with the aim to identify key mechanisms of provider responsiveness. Purposeful searches for cases were combined with a systematic search in four databases. To be included in the review, the initiatives needed to describe at least one outcome at the level of frontline service provision. Some 37 social accountability initiatives in 15 countries met these criteria. Using a realist approach, retroductive analysis and triangulation of methods and sources were performed to construct Context-Mechanism-Outcome configurations that explain potential pathways to provider responsiveness. The findings suggest that health provider receptivity to citizens' demands for better health care is mediated by health providers' perceptions of the legitimacy of citizen groups and by the extent to which citizen groups provide personal and professional support to health providers. Some citizen groups activated political or formal bureaucratic accountability channels but the effect on provider responsiveness of such strategies was more mixed. Favourable contexts for health provider responsiveness comprise socio-political contexts in which providers self-identify as activists, health system contexts in which health providers depend on citizens' expertise and capacities, and health system contexts where providers have the self-perceived ability to change the system in which they operate. Rather than providing recipes for successful social accountability initiatives, the synthesis proposes a programme theory that can support reflections on the theories of change underpinning social accountability initiatives and interventions to improve the quality of primary health care in different settings

Realist review and synthesis of retention studies for health workers in rural and remote areas

This report uses a realist review, which is a theory-based method, to address the questions of “why” and “how” certain rural retention interventions work better in some contexts and fail in others. Through applying a realist perspective to the review of these retention studies, a greater understanding is gained of the contextual factors and the main mechanisms that triggered the effects of retention strategies. The report provides strong support for the assertion that a bundle of retention strategies should be used in order to successfully attract and retain health workers in remote and rural areas. It also provides valuable recommendations for future studies and gives a better insight into why interventions that were effective in one setting may or may not produce similar results in anothe

Impact of short-term reconstructive surgical missions: A systematic review

Introduction Short-term missions providing patients in low-income countries with reconstructive surgery are often criticised because evidence of their value is lacking. This study aims to assess the effectiveness of short-term reconstructive surgical missions in low-income and middle-income countries. Methods A systematic review was conducted according to PRISMA guidelines. We searched five medical databases from inception up to 2 July 2018. Original studies of short-term reconstructive surgical missions were included, which reported data on patient safety measurements, health gains of individual patients and sustainability. Data were combined to generate overall outcomes, including overall complication rates. Results Of 1662 identified studies, 41 met full inclusion criteria, which included 48 546 patients. The overall study quality according to Oxford CEBM and GRADE was low. Ten studies reported a minimum of 6 months' follow-up, showing a follow-up rate of 56.0% and a complication rate of 22.3%. Twelve studies that did not report on duration or follow-up rate reported a complication rate of 1.2%. Fifteen out of 20 studies (75%) that reported on follow-up also reported on sustainable characteristics. Conclusions Evidence on the patient outcomes of reconstructive surgical missions is scarce and of limited quality. Higher complication rates were reported in studies which explicitly mentioned the duration and rate of follow-up. Studies with a low follow-up quality might be under-reporting complication rates and overestimating the positive impact of missions. This review indicates that missions should develop towards sustainable partnerships. These partnerships should provide quality aftercare, perform outcome research and build the surgical capacity of local healthcare systems. PROSPERO registration number CRD42018099285

Scalability of a task-sharing psychological intervention for refugees: A qualitative study in the Netherlands

Mental health systems across the world struggle to meet the needs of present and future populations. People affected by war and forced displacement, such as refugees, have especially high unmet psychological needs. Shifting tasks from mental health specialists to less specialised providers is increasingly opted as an innovative solution to overcome the mental health care gap. Yet little is known about how task-sharing interventions for refugees can be implemented on a larger scale and integrated in existing systems. In this article, we use a system innovation perspective to examine the factors influencing the potential for scaling up a task-sharing psychological intervention for refugees called ‘Problem Management Plus’ (PM+) in the Netherlands. Semi-structured interviews were conducted with individuals (n=42) knowledgeable about PM+ and the Dutch mental health system for refugees. Findings suggest that the feasibility of wider implementation largely depends on whether barriers like stigma, attrition, fragmentation, competition, legal, and financial challenges can be overcome. Formalising the roles of new non-specialist workers will be important, including developing structures for their accreditation and supervision. There are various possibilities for institutional anchoring of the innovation: in asylum centres, formal health care, and communities. The integration scenarios identified in this study need to be tested, evaluated, refined, and reported in future implementation research

Third party monitoring for health in Afghanistan: the good, the bad and the ugly

Third party monitoring (TPM) is used in development programming to assess deliverables in a contract relationship between purchasers (donors or government) and providers (non-governmental organisations or non-state entities). In this paper, we draw from our experience as public health professionals involved in implementing and monitoring the Basic Package of Health Services (BPHS) and the Essential Package of Hospital Services (EPHS) as part of the SEHAT and Sehatmandi programs in Afghanistan between 2013 and 2021. We analyse our own TPM experience through the lens of the three parties involved: the Ministry of Public Health; the service providers implementing the BPHS/EPHS; and the TPM agency responsible for monitoring the implementation. Despite the highly challenging and fragile context, our findings suggest that the consistent investments and strategic vision of donor programmes in Afghanistan over the past decades have led to a functioning and robust system to monitor the BPHS/EPHS implementation in Afghanistan. To maximise the efficiency, effectiveness and impact of this system, it is important to promote local ownership and use of the data, to balance the need for comprehensive information with the risk of jamming processes, and to address political economy dynamics in pay-for-performance schemes. Our findings are likely to be emblematic of TPM issues in other sectors and other fragile and conflicted affected settings and offer a range of lessons learnt to inform the implementation of TPM schemes
