The effectiveness of solar disinfection water treatment method for reducing childhood diarrhea: a systematic review and meta-analysis protocol

摘要

BackgroundSeveral studies employing the effectiveness of solar disinfection water treatment method for reducing diarrhea have reported heterogeneous outcomes, necessitating a systematic review to provide an exhaustive summary of current evidence. Thus, the objective of this review is to pool out the available evidence on the effectiveness of solar disinfection water treatment method for reducing childhood diarrhea.MethodsSearches will be conducted in PubMed/Medline, Scopus, Google Scholar, Cochrane Library databases, and reference of other studies published through in December 2019. Studies that compare the diarrhea incidence among the intervention group who were exposed to solar disinfection water treatment and the control group who were not exposed to such water treatment were included. The primary outcome of the study is the change in observed diarrhea incidence risk from baseline to post-intervention. Randomized controlled trial study designs will be included. Selected studies will be critically appraised by two independent reviewers. Extracted data will include details about the interventions, populations, study methods, and outcomes of significance to the review question and objectives. Effect sizes will be expressed as risk ratio, and their 95% confidence intervals will be calculated for analysis.DiscussionThis review and meta-analysis will systematically explore and integrate the evidence available on the effectiveness of solar disinfection water treatment method for reducing diarrhea. In this review, information about the potential impact of solar disinfection water treatment to inactivate pathogenic microbes for reducing diarrhea will be gathered and summarized. The findings from this study will provide directions for future research and public health professionals with an understanding of the importance of solar disinfection water treatment and point to directions for applicability of the interventions in the community.
