Contracting out to improve the use of clinical health services and health outcomes in low- and middle-income countries

Effective interventions for improving routine childhood immunisation in low and middle-income countries: a systematic review of systematic reviews

OBJECTIVE

An umbrella review providing a comprehensive synthesis of the interventions that are effective in providing routine immunisation outcomes for children in low and middle-income countries (L&MICs).

DESIGN

A systematic review of systematic reviews, or an umbrella review.

DATA SOURCES

We comprehensively searched 11 academic databases and 23 grey literature sources. The search was adopted from an evidence gap map on routine child immunisation sector in L&MICs, which was done on 5 May 2020. We updated the search in October 2021.

ELIGIBILITY CRITERIA

We included systematic reviews assessing the effectiveness of any intervention on routine childhood immunisation outcomes in L&MICs.

DATA EXTRACTION AND SYNTHESIS

Search results were screened by two reviewers independently applying predefined inclusion and exclusion criteria. Data were extracted by two researchers independently. The Specialist Unit for Review Evidence checklist was used to assess review quality. A mixed-methods synthesis was employed focusing on meta-analytical and narrative elements to accommodate both the quantitative and qualitative information available from the included reviews.

RESULTS

62 systematic reviews are included in this umbrella review. We find caregiver-oriented interventions have large positive and statistically significant effects, especially those focusing on short-term sensitisation and education campaigns as well as written messages to caregivers. For health system-oriented interventions the evidence base is thin and derived from narrative synthesis suggesting positive effects for home visits, mixed effects for pay-for-performance schemes and inconclusive effects for contracting out services to non-governmental providers. For all other interventions under this category, the evidence is either limited or not available. For community-oriented interventions, a recent high-quality mixed-methods review suggests positive but small effects. Overall, the evidence base is highly heterogenous in terms of scope, intervention types and outcomes.

CONCLUSION

Interventions oriented towards caregivers and communities are effective in improving routine child immunisation outcomes. The evidence base on health system-oriented interventions is scant not allowing us to reach firm conclusions, except for home visits. Large evidence gaps exist and need to be addressed. For example, more high-quality evidence is needed for specific caregiver-oriented interventions (eg, monetary incentives) as well as health system-oriented (eg, health workers and data systems) and community-oriented interventions. We also need to better understand complementarity of different intervention types.

Impact of health system governance on healthcare quality in low-income and middle-income countries: a scoping review

INTRODUCTION

Improving healthcare quality in low-/middle-income countries (LMICs) is a critical step in the pathway to Universal Health Coverage and health-related sustainable development goals. This study aimed to map the available evidence on the impacts of health system governance interventions on the quality of healthcare services in LMICs.

METHODS

We conducted a scoping review of the literature. The search strategy used a combination of keywords and phrases relevant to health system governance, quality of healthcare and LMICs. Studies published in English until August 2023, with no start date limitation, were searched on PubMed, Cochrane Library, CINAHL, Web of Science, Scopus, Google Scholar and ProQuest. Additional publications were identified by snowballing. The effects reported by the studies on processes of care and quality impacts were reviewed.

RESULTS

The findings from 201 primary studies were grouped under (1) leadership, (2) system design, (3) accountability and transparency, (4) financing, (5) private sector partnerships, (6) information and monitoring; (7) participation and engagement and (8) regulation.

CONCLUSIONS

We identified a stronger evidence base linking improved quality of care with health financing, private sector partnerships and community participation and engagement strategies. The evidence related to leadership, system design, information and monitoring, and accountability and transparency is limited.

Government purchasing initiatives involving private providers in the Eastern Mediterranean Region: a systematic review of impact on health service utilisation

OBJECTIVE

This paper provides a systematic review of evidence of government purchase of health services from private providers through stand-alone contracting-out (CO) initiatives and CO insurance schemes (CO-I) on health service utilisation in Eastern Mediterranean Region (EMR) to inform universal health coverage 2030 strategies.

DESIGN

Systematic review.

DATA SOURCES

Electronic search of published and grey literature on Cochrane Central Register of Controlled Trials, PubMed, CINHAL, Google Scholar and web, including websites of ministries of health from January 2010 to November 2021.

ELIGIBILITY CRITERIA

Randomised controlled trials, quasi-experimental studies, time series, before-after and endline with comparison group reporting quantitative utilisation of data across 16 low-income and middle-income states of EMR. Search was limited to publications in English or English translation.

DATA EXTRACTION AND SYNTHESIS

We planned for meta-analysis, but due to limited data and heterogeneous outcomes, descriptive analysis was performed.

RESULTS

Several initiatives were identified but only 128 studies were eligible for full-text screening and 17 met the inclusion criteria. These included CO (n=9), CO-I (n=3) and a combination of both (n=5) across seven countries. Eight studies assessed interventions at national level and nine at subnational level. Seven studies reported on purchasing arrangements with non-governmental organisations, 10 on private hospitals and clinics. Impact on outpatient curative care utilisation was seen in both CO and CO-I, positive evidence of improved maternity care service volumes was seen mainly from CO interventions and less reported from CO-I, whereas data on child health service volume was only available for CO and indicated negative impact on service volumes. The studies also suggest pro-poor effect for CO initiatives, whereas there was scarce data for CO-I.

CONCLUSION

Purchasing involving stand-alone CO and CO-I interventions in EMR positively impact general curative care utilisation, but lacks conclusive evidence for other services. Policy attention is needed for embedded evaluations within programmes, standardised outcome metrics and disaggregated utilisation data.

The effectiveness of pay-for-performance contracts with non-governmental organizations in Afghanistan - results of a controlled interrupted time series analysis

BACKGROUND

In many contexts, including fragile settings like Afghanistan, the coverage of basic health services is low. To address these challenges there has been considerable interest in working with NGOs and examining the effect of financial incentives on service providers. The Government of Afghanistan has used contracting with NGOs for more than 15 years and in 2019 introduced pay-for-performance (P4P) into the contracts. This study examines the impact of P4P on health service delivery in Afghanistan.

METHODS

We conducted an interrupted time series (ITS) analysis with a non-randomized comparison group that employed segmented regression models and used independently verified health management information system (HMIS) data from 2015 to 2021. We compared 31 provinces with P4P contracts to 3 provinces where the Ministry of Public Health (MOPH) continued to deliver services without P4P. We used data from annual health facility surveys to assess the quality of care.

FINDINGS

Independent verification of the HMIS data found that consistency and accuracy was greater than 90% in the contracted provinces. The introduction of P4P increased the 10 P4P-compensated service delivery outcomes by a median of 22.1 percentage points (range 10.2 to 43.8) for the two-arm analysis and 19.9 percentage points (range: - 8.3 to 56.1) for the one-arm analysis. There was a small decrease in quality of care initially, but it was short-lived. We found few other unintended consequences.

INTERPRETATION

P4P contracts with NGOs led to a substantial improvement in service delivery at lower cost despite a very difficult security situation. The promising results from this large-scale experience warrant more extensive application of P4P contracts in other fragile settings or wherever coverage remains low.

Contracting the private health sector in Thailand's Universal Health Coverage

Private sector plays an import role in health service provision, therefore the engagement of private health facilities is important for ensuring access to health services. In Thailand, two of the three public health insurance schemes, Universal Coverage Scheme and Social Health Insurance, contract with private health facilities to fill gaps of public providers for the provision of health services under Universal Health Coverage. The National Health Security Office (NHSO) and Social Security Office (SSO), which manage the schemes respectively, have designed their own contractual agreements for private facilities. We aim to understand the current situation of contracting private health facilities within UHC of the two purchasing agencies. This qualitative descriptive case study was conducted through document review and in-depth interviews with key informants to understand how they contract private primary care facilities, service types, duration of contract, standard and quality requirement and renewal and termination of contracts. Private providers make a small contribution to the service provision in Thailand as a whole but they are important actors in Bangkok. The current approaches used by two purchasers are not adequate in engaging private sector to fill the gap of public provision in urban cities. One important reason is that large private hospitals do not find public contracts financially attractive. NHSO classifies contracts into 3 categories: main contracting units, primary care units, and referral units; while SSO only contracts main contracting units. Both allows subcontracting by the main contractors. Contractual agreements are effective in ensuring mandatory infrastructure and quality standards. Both purchasers have established technical capacities to enforce quality monitoring and financial compliance although there remains room for improvement especially on identifying fraud and taking legal actions. Contracting private healthcare facilities can fill the gap of public healthcare facilities, especially in urban settings. Purchasers need to balance the right level of incentives and accountability measures to ensure access to quality of care. In contracting private-for-profit providers, strong regulatory enforcement and auditing capacities are necessary. Further studies may explore various aspects contracting outcomes including access, equity, quality and efficiency impacts.

Economic Aspects of Delivering Primary Care Services: An Evidence Synthesis to Inform Policy and Research Priorities

Policy Points The 2018 Declaration of Astana reemphasized the importance of primary health care and its role in achieving universal health coverage. While there is a large amount of literature on the economic aspects of delivering primary care services, there is a need for more comprehensive overviews of this evidence. In this article, we offer such an overview. Evidence suggests that there are several strategies involving coverage, financing, service delivery, and governance arrangements which can, if implemented, have positive economic impacts on the delivery of primary care services. These include arrangements such as worker task-shifting and telemedicine. The implementation of any such arrangements, based on positive economic evidence, should carefully account for potential impacts on overall health care access and quality. There are many opportunities for further research, with notable gaps in evidence on the impacts of increasing primary care funding or the overall supply of primary care services.

CONTEXT

The 2018 Declaration of Astana reemphasized the importance of primary health care and its role in achieving universal health coverage. To strengthen primary health care, policymakers need guidance on how to allocate resources in a manner that maximizes its economic benefits.

METHODS

We collated and synthesized published systematic reviews of evidence on the economic aspects of different models of delivering primary care services. Building on previous efforts, we adapted existing taxonomies of primary care components to classify our results according to four categories: coverage, financing, service delivery, and governance.

FINDINGS

We identified and classified 109 reviews that met our inclusion criteria according to our taxonomy of primary care components: coverage, financing, service delivery, and governance arrangements. A significant body of evidence suggests that several specific primary care arrangements, such as health workers' task shifting and telemedicine, can have positive economic impacts (such as lower overall health care costs). Notably absent were reviews on the impact of increasing primary care funding or the overall supply of primary care services.

CONCLUSIONS

There is a great opportunity for further research to systematically examine the broader economic impacts of investing in primary care services. Despite progress over the last decade, significant evidence gaps on the economic implications of different models of primary care services remain, which could help inform the basis of future research efforts.

Engagement of non-governmental organisations in moving towards universal health coverage: a scoping review

BACKGROUND

Developing essential health services through non-governmental organisations (NGOs) is an important strategy for progressing towards Universal Health Coverage (UHC), especially in low- and middle-income countries. It is crucial to understand NGOs' role in reaching UHC and the best way to engage them.

OBJECTIVE

This study reviewed the role of NGOs and their engagement strategies in progress toward UHC.

METHOD

We systematically reviewed studies from five databases (PubMed, Web of Science (ISI), ProQuest, EMBASE and Scopus) that investigated NGOs interventions in public health-related activities. The quality of the selected studies was assessed using the mixed methods appraisal tool. PRISMA reporting guidelines were followed.

FINDINGS

Seventy-eight studies met the eligibility criteria. NGOs main activities related to service and population coverage and used different strategies to progress towards UHC. To ensure services coverage, NGOs provided adequate and competent human resources, necessary health equipment and facilities, and provided public health and health care services strategies. To achieve population coverage, they provided services to vulnerable groups through community participation. Most studies were conducted in middle-income countries. Overall, the quality of the reported evidence was good. The main funding sources of NGOs were self-financing and grants from the government, international organisations, and donors.

CONCLUSION

NGOs can play a significant role in the country's progress towards UHC along with the government and other key health players. The government should use strategies and interventions in supporting NGOs, accelerating their movement toward UHC.

Which public health interventions are effective in reducing morbidity, mortality and health inequalities from infectious diseases amongst children in low- and middle-income countries (LMICs): An umbrella review

Despite significant progress in the last few decades, infectious diseases remain a major threat to child health in low- and middle-income countries (LMICs)—particularly amongst more disadvantaged groups. It is imperative to understand the best available evidence concerning which public health interventions reduce morbidity, mortality and health inequalities in children aged under five years. To address this gap, we carried out an umbrella review (a systematic reviews of reviews) to identify evidence on the effects of public health interventions (promotion, protection, prevention) on morbidity, mortality and/or health inequalities due to infectious diseases amongst children in LMICs. Ten databases were searched for records published between 2014–2021 alongside a manual search of gray literature. Articles were quality-assessed using the Assessment of Multiple Systematic Reviews tool (AMSTAR 2). A narrative synthesis was conducted. We identified 60 systematic reviews synthesizing 453 individual primary studies. A majority of the reviews reported on preventive interventions (n = 48), with a minority on promotion (n = 17) and almost no reviews covering health protection interventions (n = 2). Effective interventions for improving child health across the whole population, as well as the most disadvantaged included communication, education and social mobilization for specific preventive services or tools, such as immunization or bed nets. For all other interventions, the effects were either unclear, unknown or detrimental, either at the overall population level or regarding health inequalities. We found few reviews reporting health inequalities information and the quality of the evidence base was generally low. Our umbrella review identified some prevention interventions that might be useful in reducing under five mortality from infectious diseases in LMICs, particularly amongst the most disadvantaged groups.

Perspectives on Building Sustainable Newborn Screening Programs for Sickle Cell Disease: Experience from Tanzania

The prevalence of sickle cell disease is high in Africa, with significant public health effects on the affected countries. Many of the countries with the highest prevalence of the disease also have poor health care systems and a high burden of infectious diseases with many other competing health care priorities. Although considerable efforts have been made to implement newborn screening for sickle cell disease programs in Africa, coverage is still low. Tanzania has one of the highest birth prevalence of children with sickle cell disease in Africa. In 2015, the country implemented a pilot project for Newborn Screening for Sickle Cell Disease to assess feasibility. Several efforts have been made afterwards to continue providing the screening services as well as related comprehensive care services. Using qualitative methods, we conducted in-depth interviews and focus group discussions with policy makers (n = 4), health care providers (n = 21) and families (n = 15) to provide an analysis of their experiences and perspectives on efforts to expand and sustain newborn screening for sickle cell disease and related comprehensive care services in the country. Thematic content analysis was used to analyze the data through the framework analysis method. The findings have demonstrated both the opportunities and areas that need addressing in the implementation and sustainability of the services in low resource settings. A key area of strengthening is full integration of the services in countries' health care systems to facilitate the coverage, accessibility and affordability of the services. Although the coverage of newborn screening services for sickle cell disease is still low, efforts at the local level to sustain the implementation of the programs and related comprehensive care services are encouraging and can be used as a model for other programs implemented in low resources settings.

Contracting as a bridging factor linking outer and inner contexts during EBP implementation and sustainment: a prospective study across multiple U.S. public sector service systems

BACKGROUND

Bridging factors are relational ties (e.g. partnerships), formal arrangements (e.g. contracts or polices) and processes (e.g. data sharing agreements) linking outer and inner contexts and are a recent evolution of the Exploration-Preparation-Implementation-Sustainment (EPIS) framework. Bridging factor research can elucidate ways that service systems may influence and/or be influenced by organizations providing health services. This study used the EPIS framework and open systems and resource dependence theoretical approaches to examine contracting arrangements in U.S. public sector systems. Contracting arrangements function as bridging factors through which systems communicate, interact, and exchange resources with the organizations operating within them.

METHODS

The sample included 17 community-based organizations in eight service systems. Longitudinal data is derived from 113 contract documents and 88 qualitative interviews and focus groups involving system and organizational stakeholders. Analyses consisted of a document review using content analysis and focused coding of transcripts from the interviews and focus groups. A multiple case study analysis was conducted to identify patterns across service systems and organizations. The dataset represented service systems that had sustained the same EBP for between 2 and 10 years, which allowed for observation of bridging factors and outer-inner context interactions over time.

RESULTS

Service systems and organizations influenced each other in a number of ways through contracting arrangements. Service systems influenced organizations when contracting arrangements resulted in changes to organizational functioning, required organizational responses to insufficient funding, and altered interorganizational network relationships. Organizations influenced service systems when contract arrangements prompted organization-driven contract negotiation/tailoring, changes to system-level processes, and interorganizational collaboration. Service systems and organizations were dependent on each other as implementation progressed. Resources beyond funding emerged, including adequate numbers of eligible clients, expertise in the evidence-based practice, and training and coaching capacity.

CONCLUSION

This study advances implementation science by expanding the range and definition of bridging factors and illustrating specific bi-directional influences between outer context service systems and inner context organizations. This study also identifies bi-directional dependencies over the course of implementation and sustainment. An analysis of influence, dependencies, and resources exchanged through bridging factors has direct implications for selecting and tailoring implementation strategies, especially those that require system-level coordination and change.

Participation in the state led 'Janani Sahayogi Yojana' public private partnership program to promote facility births in Madhya Pradesh, India: views from private obstetrician partners

BACKGROUND

In Madhya Pradesh, India, the government invited private obstetric hospitals for partnership to provide intrapartum care to poor women, paid for by the state. This statewide program, the Janani Sahayogi Yojana (JShY or maternal support scheme), ran from 2006 to 2012. The partnership was an uneasy one with many private obstetricians choosing to leave the partnership. This paper explores the motives of private obstetricians in the state for participating in the JShY, their experiences within the partnership, their interactions with the state and motives for withdrawal among those who withdrew from the scheme. This study sheds light on the dynamics of a public-private partnership for obstetric care from the perspective of private sector obstetricians.

METHOD

Fifteen in-depth interviews were conducted with private obstetricians and hospital administrators from eight districts of Madhya Pradesh who had participated in the JShY. A Framework approach was used to analyze the data.

RESULTS

Private obstetricians reported entering the JShY partnership for altruistic reasons but also as way of expanding their practices and reputations. They perceived that although their facilities provided better quality of care than state facilities, participation was risky because beneficiaries were often unbooked and seen as 'high risk' cases. The need to arrange for blood transfusions for these high risk women was perceived as particularly difficult. Cumbersome paper work and delays in receiving payments from the state also dissuaded participation. Some participants felt that there was inadequate engagement by the state, and better monitoring and supervision would have helped. The state changed the financial reimbursement arrangements due to a high proportion of Cesarean births in the early years of the partnership, as these were perversely incentivized. This change resulted in a large exodus of private obstetricians from the partnership.

CONCLUSION

This study highlights the contribution of cumbersome processes, trust deficits and a lack of dialogue between public and private partners. Input from both public and private sectors into the design of a carefully thought through financial reimbursement package for private partners was highlighted as a necessary component for future success of such schemes.

Contracting non-state providers for universal health coverage: learnings from Africa, Asia, and Eastern Europe

BACKGROUND

Formal engagement with non-state providers (NSP) is an important strategy in many low-and-middle-income countries for extending coverage of publicly financed health services. The series of country studies reviewed in this paper - from Afghanistan, Bangladesh, Bosnia & Herzegovina, Ghana, South Africa, Tanzania and Uganda - provide a unique opportunity to understand the dynamics of NSP engagement in different contexts.

METHODS

A standard template was developed and used to summarize the main findings from the country studies. The summaries were then organized according to emergent themes and a narrative built around these themes.

RESULTS

Governments contracted NSPs for a variety of reasons - limited public sector capacity, inability of public sector services to reach certain populations or geographic areas, and the widespread presence of NSPs in the health sector. Underlying these reasons was a recognition that purchasing services from NSPs was necessary to increase coverage of health services. Yet, institutional NSPs faced many service delivery challenges. Like the public sector, institutional NSPs faced challenges in recruiting and retaining health workers, and ensuring service quality. Properly managing relationships between all actors involved was critical to contracting success and the role of NSPs as strategic partners in achieving national health goals. Further, the relationship between the central and lower administrative levels in contract management, as well as government stewardship capacity for monitoring contractual performance were vital for NSP performance.

CONCLUSION

For countries with a sizeable NSP sector, making full use of the available human and other resources by contracting NSPs and appropriately managing them, offers an important way for expanding coverage of publicly financed health services and moving towards universal health coverage.
