Quality of reporting of literature search strategies in systematic reviews published on the role of telehealth during COVID-19

Abstract

A comprehensive and reproducible search strategy for systematic reviews especially about COVID-19 plays a pivotal role in conducting a reliable and unbiased review. The primary aim of this study was to investigate the quality of the search strategy reporting in systematic reviews conducted on the role of telehealth during COVID-19. The secondary aim of study was to explore some affecting factor in the quality of search strategy. The study evaluated the quality of the search strategy reporting with PRISMA-S checklist. The search was performed in MEDLINE, Embase, CINAHL, and other related databases. Systematic reviews were included. There was no language restriction. The correlation of the PRISMA-S scores with journal impact factor, CiteScore, and librarians’ role were evaluated using Spearman’s rank correlation coefficient. A total of 85 articles were included in the review. The overall mean score of PRISMA-S checklist was 6.12 ± 1.46. PubMed was the most popular database for search. More than half of the studies did not provide a full search strategy. There was a significant positive correlation between PRISMA-S score and the journal impact factor (Spearman’s rho = 0.217; P = 0.46) and CiteScore (Spearman’s rho = 0.235; P = 0.03). The quality of literature search was poor in the included studies. Using the PRISMA-S as a search reporting guideline can be a helpful tool for authors. A professional librarian can be beneficial in improving the quality of the search. It is recommended to use a new pattern in COVID-19-related searches, such as preprint sources.
