While moving towards unified social health insurance (SHI) is often a politically popular policy reform in countries where rapid expansion in health insurance coverage has given rise to the segmentation of SHI systems as different SHI schemes were rolled out to serve different populations, the potential impacts of reform on service utilisation and health costs have not been systematically studied. Using data from the Chinese Health and Retirement Longitudinal Study (CHARLS), we compared the mean costs incurred for both inpatient and outpatient care under different health insurance schemes, and the impact of different SHI schemes on treatment utilisation and health care costs using a two-part model. Our results show that Urban Employee Medical Insurance, which offers the most generous benefits, incurs the highest total costs prior to reimbursement when compared to other SHI schemes. Our analysis also shows that utilisation of SHI did not show significant reduction in out-of-pocket payments for outpatients. We argue that, unless effective measures are introduced to deal with perverse provider payment incentives, the move towards a unified system with more generous benefits may usher in a new wave of cost escalation for health care systems in China.
The reform of provider payment systems, from retrospective to prospective payment, has been heralded as the right move to contain costs in the light of rising health expenditures in many countries. However, there are concerns on quality trade-off. The heightened attention given to prospective payment system (PPS) reforms and the rise of empirical evidence regarding PPS interventions among developing countries suggest that a systematic review is necessary to understand the effects of PPS reforms in developing countries. A systematic search of 14 databases and a hand search of health policy journals and grey literature from October to November 2016 were carried out, guided by a set of inclusion and exclusion criteria. Data were extracted based on the Consolidated Health Economics Evaluation Reporting Standards checklist. Drummond's 10-item checklist for economic evaluation, Cochrane Collaboration's tool in assessing risk of bias for randomized trials, and Risk of Bias in Non-randomized Studies of Interventions were used to critically appraise the evidence. A total of 12 studies reported in China, Thailand and Vietnam were included in this review. Substantial heterogeneity was present in PPS policy design across different localities. PPS interventions were found to have reduced health expenditures on both the supply and demand side, as well as length of stay and readmission rates. In addition, PPS generally improved service quality outcomes by reducing the likelihood or percentage of physicians prescribing unnecessary drugs and diagnostic procedures. PPS is a promising policy tool for middle-income countries to achieve reasonable health policy objectives in terms of cost containment without necessarily compromising the quality of care. More evaluations of PPS will need to be conducted in the future in order to broaden the evidence base beyond middle-income countries.
Female sex work accounts for about 15% of the global HIV burden in women. Asia is the region with the second highest attributable fraction of the HIV epidemic after sub-Saharan Africa. This review synthesises studies that depict the barriers and facilitators encountered by sex workers in Asia when negotiating consistent condom use. A total of 18 studies published between January 1989 and May 2015 were included in the review. Data were extracted, critically appraised and analysed using a thematic analysis approach. Individual-level factors related to sex workers' knowledge, perception and power, as well as interpersonal-level factors that encompassed dynamics with clients and peer-related factors, presented as both barriers and facilitators to sex workers' condom negotiation process. In addition, the structural environment of sex work, access to resources, poverty, stigma, the legal environment and the role of media were also identified as factors in influencing the condom negotiation process of sex workers. A multisectoral interventional approach that addresses the multilevel barriers encountered by sex workers in condom negotiation is needed. Awareness of safe-sex practice should be collectively enhanced among sex workers, clients and brothel managers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
