Cost and cost-effectiveness of treatments for rheumatic heart disease in low- and middle-income countries: a systematic review protocol

Abstract

Objective: This review will synthesize studies on costs, the impact of these costs, and the cost-effectiveness of treatments for rheumatic heart disease (RHD) in low- and middle-income countries. Introduction: RHD incurs high costs owing to its clinical complexity, surgical treatments, and prolonged hospital stays. Thus, the disease has a substantial economic impact on the health system, patients, and their families. No systematic review on economic evidence of treatments for RHD has been published to date. Inclusion criteria: This review will consider all cost and cost-effectiveness studies on RHD treatments for children and young adults (5─30 years) residing in low- and middle-income countries. Methods: The review will follow the JBI methodology for systematic reviews of economic evaluation evidence. The search strategy will locate published and unpublished studies in English. Systematic searches will be conducted in MEDLINE (PubMed), MEDLINE (Ovid), Embase (Ovid), Scopus, CINAHL (EBSCOhost), National Health Service Economic Evaluation Databases, Pediatric Economic Database Evaluation, and Cost-Effectiveness Analysis Registry. Two independent reviewers will screen titles and abstracts, followed by a full-text review based on the inclusion criteria. Data will be extracted using a modified JBI data extraction form for economic evaluations. JBI’s Dominance Ranking Matrix for economic evaluations will be used to summarize and compare the results of cost and cost-effectiveness studies. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach will be used to assess the certainty of economic evidence for outcomes related to resource use.
