Abstract
To systematically analyse the effects of evidence-based nursing (EBN) in preventing the development of pressure ulcers (PUs) in intensive care unit (ICU) patients. We conducted a computerised search of the Embase, PubMed, Cochrane Library, Web of Science, China National Knowledge Infrastructure and Wanfang databases for randomised controlled trials on the prevention of PUs in ICU patients by EBN, published before the respective databases were established until September 2023. Two investigators independently performed literature screening, data extraction and quality assessment. A meta-analysis was performed using Stata 17.0. Eighteen papers were included, comprising 2593 patients, of whom 1297 and 1296 received EBN and conventional nursing, respectively. The incidence of PUs was 2.70% and 12.04% in the EBN and conventional nursing groups, respectively. Meta-analysis showed a statistically significantly lower incidence of PUs in the EBN group than that in the conventional nursing group (risk ratio = 0.22, 95% confidence interval: 0.16-0.32, p < 0.001). EBN interventions are more effective than conventional nursing in preventing PUs in ICU patients. However, since the literature included in this study was from China, the conclusions require further confirmation via higher-quality studies.
