While World Health Organization member countries embraced the concept of universal coverage as early as 2005, few low-income countries have yet achieved the objective. This is mainly due to numerous barriers that hamper access to needed health services. In this paper we provide an overview of the various dimensions of barriers to access to health care in low-income countries (geographical access, availability, affordability and acceptability) and outline existing interventions designed to overcome these barriers. These barriers and consequent interventions are arranged in an analytical framework, which is then applied to two case studies from Cambodia. The aim is to illustrate the use of the framework in identifying the dimensions of access barriers that have been tackled by the interventions. The findings suggest that a combination of interventions is required to tackle specific access barriers but that their effectiveness can be influenced by contextual factors. It is also necessary to address demand-side and supply-side barriers concurrently. The framework can be used both to identify interventions that effectively address particular access barriers and to analyse why certain interventions fail to tackle specific barriers.

Most health system strengthening interventions ignore interconnections between systems components. In particular, complex relationships between medicines and health financing, human resources, health information and service delivery are not given sufficient consideration. As a consequence, populations' access to medicines (ATM) is addressed mainly through fragmented, often vertical approaches usually focusing on supply, unrelated to the wider issue of access to health services and interventions. The objective of this article is to embed ATM in a health system perspective. For this purpose, we perform a structured literature review: we examine existing ATM frameworks, review determinants of ATM and define at which level of the health system they are likely to occur; we analyse to which extent existing ATM frameworks take into account access constraints at different levels of the health system. Our findings suggest that ATM barriers are complex and interconnected as they occur at multiple levels of the health system. Existing ATM frameworks only partially address the full range of ATM barriers. We propose three essential paradigm shifts that take into account complex and dynamic relationships between medicines and other components of the health system. A holistic view of demand-side constraints in tandem with consideration of multiple and dynamic relationships between medicines and other health system resources should be applied; it should be recognized that determinants of ATM are rooted in national, regional and international contexts. These are schematized in a new framework proposing a health system perspective on ATM.

This article presents research findings into the effectiveness of an innovative equity fund approach to improving access to public sector health services for the poor in Kirivong Operational Health District in Cambodia. The operational health district is the lowest organizational level in the Cambodian health system, providing services through health centres and a single referral hospital. An equity fund involves a third party identifying the poor and paying user fees on their behalf by reimbursing the service provider, thus relieving health staff of such responsibility. We explore the appropriateness of utilizing community members to identify the poorest. The impact of newly introduced pagoda-managed equity funds on access to public health services for the poorest, and on their out-of-pocket expenditure during illness episodes, is then examined. We conclude with an evaluation of the contribution of the equity funds to community participation. The research indicates that identification by community members of those eligible for equity funds is feasible, accrues minimal direct costs, and is effective. Households identified as eligible for equity fund benefits were poorer than those identified as non-beneficiaries. Direct costs associated with seeking care were considerably lower for equity fund beneficiaries than for non-beneficiaries, and fewer beneficiaries than non-beneficiaries initially consulted the private sector, providing evidence of the equity fund's ability to attract the poorest to the public sector. The level and nature of community participation was enhanced considerably following the introduction of the pagoda-managed equity funds. In order to maximize and sustain the equity benefits of such funds, we recommend that external agencies (such as international non-governmental organizations) limit their role to the provision of technical support and advice, rather than taking the lead on implementation and administration. Facilitating the design, implementation, administration and management of equity funds by indigenous community-based organizations has the advantage of not only greatly reducing administrative costs, allowing a large proportion of the fund to be spent on services for the poor, but also of enhancing local ownership, thus increasing the likelihood of equity funds being sustained in the future.

BackgroundThe Government of Lao Peoples’ Democratic Republic (Lao PDR) has embarked on a path to achieve universal health coverage (UHC) through implementation of four risk-protection schemes. One of these schemes is community-based health insurance (CBHI) – a voluntary scheme that targets roughly half the population. However, after 12 years of implementation, coverage through CBHI remains very low. Increasing coverage of the scheme would require expansion to households in both villages where CBHI is currently operating, and new geographic areas. In this study we explore the prospects of both types of expansion by examining household and district level data.MethodsUsing a household survey based on a case-comparison design of 3000 households, we examine the determinants of enrolment at the household level in areas where the scheme is currently operating. We model the determinants of enrolment using a probit model and predicted probabilities. Findings from focus group discussions are used to explain the quantitative findings. To examine the prospects for geographic scale-up, we use secondary data to compare characteristics of districts with and without insurance, using a combination of univariate and multivariate analyses. The multivariate analysis is a probit model, which models the factors associated with roll-out of CBHI to the districts.ResultsThe household findings show that enrolment is concentrated among the better off and that adverse selection is present in the scheme. The district level findings show that to date, the scheme has been implemented in the most affluent areas, in closest proximity to the district hospitals, and in areas where quality of care is relatively good.ConclusionsThe household-level findings indicate that the scheme suffers from poor risk-pooling, which threatens financial sustainability. The district-level findings call into question whether or not the Government of Laos can successfully expand to more remote, less affluent districts, with lower population density. We discuss the policy implications of the findings and specifically address whether CBHI can serve as a foundation for a national scheme, while exploring alternative approaches to reaching the informal sector in Laos and other countries attempting to achieve UHC.
