2.3. Study Selection and Data Extraction

The retrieved records were imported into the EndNote Ver.8 (Clarivate Analytics, Philadelphia, PA, USA), and then the duplicates were removed. The collected articles were restructured and numbered by order. Two independent researchers (V.R.; J.S.) screened the titles, abstracts, and full texts of potentially eligible studies. Data were extracted in PRISMA-ScR Checklist. The research team conducted the appraisal collaboratively and full-text versions were evaluated to determine inclusion and exclusion by two reviewers (J.S.; W.H.). The team supervisors (T.H.K; S.G.L) examined the reviewed articles to resolve any disagreements through several meetings. The reference lists of relevant articles were also examined for other potential eligibility for selection. It was followed by data extraction, including author names, publication year, sample size, study design, study period (years), primary outcome, time of readmission, measurement, type of readmissions (through an emergency visit, inpatient department, or both, transfer from the other hospitals), and findings. We then assessed for data evaluating study design, methodology, and reporting.
