Abstract

Background

A systematic review is used to investigate the best available evidence of clinical safety and effectiveness of healthcare intervention. This requires methodological rigor in order to minimize bias and random error. The purpose of this study is to assess the quality of systematic reviews or meta-analyses for nursing interventions conducted by Korean researchers.

Methods

We searched electronic databases from 1950 to July 2010, including ovidMEDLINE, ovidEMBASE, and Korean databases, including KoreaMed, Korean Medical Database, and Korean studies Information Service System etc. Two reviewers independently screened and selected all references, and assessed the quality of systematic reviews or meta-analyses using the “Assessment of Multiple Systematic Reviews" (AMSTAR) tool.

Results

Twenty two systematic reviews or meta-analyses were included in this study. The median overall score (out of 11) for included reviews was 5 (range 2–11) and the mean overall score for AMSTAR was 4.7 (95% confidence interval 3.8-5.7). Nine out of 22 reviews were rated as low quality (AMSTAR score 0–4), 11 were rated as moderate quality (AMSTAR score 5–8), and two reviews were categorized as high quality (AMSTAR score 9–11).

Conclusions

The methodological quality of published reviews on nursing interventions conducted by Korean reviewers was assessed as low to moderate. In order to use the best available evidence in clinical decision making, reviewers should conduct systematic reviews or meta- analyses using rigorous research methods.
