Abstract
We performed a meta-analysis to evaluate the education effects on nurses' ability to care for subjects with pressure injuries. A systematic literature search up to April 2021 was carried out, and 29 studies included 5704 nurses at the start of the study; 3800 of them were experiment or post-training and 3804 were control or per-training. They were reporting relationships between the education effects on nurses' ability to care for subjects with pressure injuries. We calculated the odds ratio (OR) or the mean difference (MD) with 95% confidence intervals (CIs) to assess the education effects on nurses' ability to care for subjects with pressure injuries using the dichotomous or continuous method with a random or fixed-effect model. Experiment or post-trained nurses had significantly higher knowledge score (MD, 10.00; 95% CI, 7.61-12.39, P < .001), number of nurses with proper knowledge (OR, 20.70; 95% CI, 10.80-39.67, P < .001), practice score (MD, 12.39; 95% CI, 5.37-19.42, P < .001), and number of nurses with proper practice (OR, 3.56; 95% CI, 1.75-7.25, P < .001), attitudes score (MD, 7.46; 95% CI, 2.94-11.99, P < .001) compared with control or pertained nurses. Training may have a beneficial effect on improving the nurses' ability to care for subjects with pressure injuries, which was obvious in improving knowledge, practice, and attitudes post-training. Further studies are required to validate these findings.
