Gastrointestinal cancer prevention policies: A qualitative systematic review and meta-synthesis

Abstract

This qualitative systematic review was conducted to summarize the policies for prevention of common gastrointestinal cancers worldwide. This study was conducted using PubMed, Web of Science, SCOPUS, and ProQuest databases. Two independent reviewers assessed included studies for methodological quality and extracted data by using standardized tools from Joanna Briggs Institute (JBI). Primary study findings were read and reread to identify the strategies or policies used in the studies for prevention of gastrointestinal cancers. The extracted findings were categorized on the basis of their similarity in meaning. These categories were then subjected to a meta-synthesis. The final synthesized findings were graded according to the ConQual approach for establishing confidence in the output of qualitative research synthesis. From the nine included studies in this review, 39 findings were extracted and based on their relevance in meaning were aggregated into 12 categories. Four synthesized findings were developed from these categories. We used World Health Organization report on 2000 for synthesizing the findings. The four synthesized findings were “service provision”, “resource generation”, “financing”, and “stewardship”. In order to reach a comprehensive evidence informed policy package for the prevention of gastrointestinal cancers, there should be a great communication among the interventions conducted directly on patients, health system infrastructures, and resources.
