Assessing nurses' attitudes towards pressure ulcer prevention: an updated systematic review.

The aim of this systematic review was to critically appraise and synthesise the existing research literature pertaining to nurses' attitudes toward pressure ulcer (PU) prevention. The systematic review presented in our paper serves as an updated version of the definitive review conducted by Avsar et al. in 2019. Using systematic review methodology, we considered published quantitative studies focusing on nurses' attitudes toward PU prevention as measured using psychometric tests. The search was conducted in April 2022, using PubMed, CINAHL, Scopus, Cochrane and EMBASE databases, and returned 454 records, of which 35 met the inclusion criteria. Data were extracted using a pre-designed extraction tool and all included studies were quality appraised using the evidence-based librarianship (EBL) appraisal checklist. In most studies, distinct measurement instruments were used for measuring nurses' attitudes toward the prevention of PUs: the Moore and Price Attitude Scale and the Attitude towards Pressure Ulcer Prevention Instrument (APuP). In this first update, the mean attitude score was 69% (±14%, range: 33.6-89%). A separate analysis of the new studies alone included in this first update (n=14) indicated a mean attitude score of 62.25% (±17.9%; median: 14%), suggesting a 10.75% lower mean attitude score. In total, 46% (n=16) yielded a score ≥75%. Conversely, Avsar et al. in 2019, 86% (n=18) of studies yielded positive attitude results. Studies from the Middle East show the lowest mean attitude score (mean 55%; ±15%; median 53%; n=9), with studies from Europe displaying the highest mean attitude score (mean 79%; ±6%; median 79%; n=12). The findings suggest that, overall, nurses are relatively positively disposed toward PU prevention. However, there are differences across continents. It is important to highlight also that the nurses have difficulties reflecting this positive attitude into actual preventative strategies.
