[A quality assessment of meta-analyses of nursing in South Korea]

The purpose of the study was to assess the quality of meta-analyses on nursing published in South Korea.

Relevant meta-analyses were identified through searches of the National Assembly Library, KISS (Korean Studies Information Service System), and the DBpia and RISS4U databases from 1990 to May 2013. Quality assessments were conducted using AMSTAR, a validated tool for assessing the quality of systematic reviews.

Forty-two meta-analyses were included in this study. Twenty-nine published between 1990 and 2010, and 13, between 2011 and May 2013. Two high quality studies and 11 moderate quality studies were published in the latter period. The mean score for the reviews was 5.61 (range 3-10); 11 studies were rated as low quality, 29 as moderate quality, and two as high quality.

Although an improvement in the quality of meta-analyses conducted by nursing researchers in South Korea was observed across the study period, the study results indicate a need to use of more rigorous research methods when conducting systematic reviews or meta-analyses.
