Predictors of Patient Participation in Pressure Injury Prevention: An Observational Substudy

Patient participation improves patient outcomes, but factors that predict participation in pressure injury prevention (PIP) are relatively unknown. This study aimed to identify patient-related factors predictive of patient participation in pressure injury prevention (PPPIP) in hospitalised medical and surgical patients and to assess the psychometric properties of the PPPIP scale. This observational substudy recruited consenting adults at risk of pressure who participated in a parent trial. The seven-item PPPIP scale was administered within 48 h of recruitment, with higher scores reflecting more participation. Multiple regression was used to identify patient-related factors predictive of patient participation. The scale's psychometric properties were assessed using confirmatory factor analysis and Cronbach's alpha. In total, usable data were obtained from 856 patients. Mean PPPIP scale scores were relatively high, with 571 (66.7%) scores reflecting agreement or strong agreement. The Cronbach's alpha was 0.81, and most confirmatory factor analysis criteria for construct validity were met. Only the use of mobility aids was statistically significant in the model, but it predicted a small amount of variability in PPPIP score (adjusted R² = 0.017; p < 0.001). Targeting patients with limited mobility may be a useful strategy when trying to engage patients in PIP if resources are limited.
