Objective: To provide up-to-date, systematic pooled evidence on the effect of educational training on nurses' knowledge and classification skills related to pressure injuries.


Data Sources: The authors searched the following databases: MEDLINE, EMBASE, ScienceDirect, Google Scholar, and Cochrane library.


Study Selection: Two investigators independently performed the primary screening (title, abstract, and keywords). Of the 903 articles identified, 99 studies met the eligibility criteria, and their full texts were reviewed. Of these, nine studies totaling 25,723 participants satisfied the inclusion criteria and were included in the review.


Data Extraction: Manual data extraction was performed by the primary investigator using a predefined, semistructured form and was checked for accuracy by secondary investigators.


Data Synthesis: The majority of the included studies (five out of nine) were low quality. For knowledge score, the pooled standardized mean difference was 1.60 (95% CI, 0.79-2.41), P < .001. For classification skills, the pooled risk ratio was 1.20 (95% CI, 1.12-1.28).


Conclusions: Educational training was relatively effective in improving nurses' pressure injury knowledge and classification skills, although the studies in this review exhibited significant heterogeneity.
