Methodological Quality of Systematic Reviews and Meta-Analysis of Interventions Published In Korean Nursing Journals: A Cross-Sectional Study

Purpose: This study aimed to assess the methodological quality and characteristics of systematic reviews and meta-analyses of interventions published in Korean nursing journals using the AMSTAR 2 tool (A Measurement Tool to Assess Systematic Reviews). Methods: This was a cross-sectional study. We searched KNBase to identify systematic reviews published between 2020 and May 2024. Independent paired reviewers from the review team appraised the methodological quality using AMSTAR 2. Any discrepancies were resolved through team discussions. Results: A total of 36 reviews were included. Among them, 16 systematic reviews (SRs) were rated as having very low confidence, 7 SRs as having low confidence, and 4 SRs as having high confidence. Fifteen SRs (41.7%) provided a pre-defined protocol, 16 SRs (44.4%) included a list of excluded studies with reasons, and 21 SRs (58.3%) considered the risk of bias in individual studies when interpreting the review results. Conclusion: The methodological quality of two-thirds of the included SRs was rated as low or very low. Future review authors should enhance methodological quality by registering a priori protocols, providing a list of excluded studies with justifications, accounting for the risk of bias in included primary studies when interpreting results, and reporting funding sources in primary studies.
