Critical Care Nurses' Knowledge, Attitudes, and Practices Regarding Pressure Injury Treatment: A Nationwide Cross-Sectional Survey

Background: Pressure injury is a common problem in intensive care units. Critical care nurses play an important role in multidisciplinary teams performing pressure injury treatment. Identifying the clinical status of pressure injury treatment may contribute to improving care quality.Aim: To identify the knowledge, attitudes, and practices regarding pressure injury treatment in critical care nurses.Design: A cross-sectional survey.Methods: Secondary data were extracted from a multicenter clinical trial. Knowledge and attitudes toward pressure injury treatment were assessed through a self-administered eight-item questionnaire. The observed practices were recorded using a case report form. The report was in accordance with the STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) statement.Results: A total of 950 critical care nurses in 15 hospitals from six provinces/municipalities of China were investigated. The mean knowledge score was 2.89 +/- 1.16 (95% confidence interval: 2.82-2.97) out of a possible total of 5 points. The correct rates of selecting wound dressings and pain management were 34.4% and 45.6%, respectively. The mean attitude score was 9.07 +/- 1.09 (95% confidence interval: 9.00-9.13) out of a possible total of 12 points. A total of 2092 patient days of pressure injury treatment practices were observed and recorded. Repositioning was the most commonly employed treatment measure (98.8%). Foam dressing was the common dressing for stage I (53.6%), stage II (47.5%), and more severe pressure injury (67.9%), including stage III, IV, unstageable, and suspected deep tissue injury.Conclusion: Critical care nurses exhibited a generally low level of knowledge and moderate attitudes regarding pressure injury treatment. Practices of pressure injury treatment were generally acceptable.
