Effectiveness of interventions to contain out-of-pocket-expenditure in lower-middle income countries: A systematic review and synthesis

The extant literature on myriad interventional strategies to contain the adverse financial impacts of soaring out-of-pocket expenditures commands systematic auditing and knowledge synthesis. The purpose of this study is to answer these specific questions. What are the interventions present in lower-middle-income countries? How effective are those interventions in reducing the household's out-of-pocket expenditure? Are the studies suffering from any methodological bias? The imprints for this systematic review are obtained from Scopus, PubMed, Web of Science, ProQuest and CINAHL. These manuscripts are identified in full compliance with PRISMA guidelines. The documents identified have undergone quality assessment checks using the ‘Effective Public Health Practice Project’. The review identified Interventions that are found to reduce out-of-pocket expenditure are patient educational programs, a combination of financial assistance, healthcare facility quality upgrade measures, and early disease detection strategies. However, these reductions represented marginal changes in the total health expenditure of patients. The role of non-health insurance interventions and the combination of health insurance and non-health insurance measures are highlighted. This review concludes by emphasising the need for further research to fill the knowledge gap by building on the suggestions put forward.
