Nurses' knowledge, attitude and practice in preventing medical device-related pressure injuries and its influencing factors: A cross-sectional study.

Aim: The purpose of this study was to explore the knowledge, attitude, and practice about preventing medical device-related pressure injuries among Chinese nurses.

Method: A cross-sectional survey was used to gather self-reported data from 2236 nursing staff, from 164 nursing units in a tertiary hospital of China by using MDRPI knowledge, attitude, and practice questionnaire.

Results: The median total score for nursing staff in preventing MDRPI is 151 (with a quartile range of 138-165) points, and the score rate is 79.40 %，the median total score for the knowledge dimension is 54 (with a quartile range of 45-60), with a score rate of 70.67 %, the median total score for the attitude dimension is 37 (with a quartile range of 36-44), with a score rate of 85.06 %，the median total score for the practice dimension is 59 (with a quartile range of 55-68), with a score rate of 85.48 %. Multiple linear regression analysis indicated that position and whether training or not are key factors influencing the total score of nursing staff in MDRPI prevention.

Conclusions: The study found that while nurses' attitude and practice score in preventing MDRPI are high, there is room for improvement in their knowledge score. Factors such as nurse position and training were identified as promoting MDRPI prevention. To enhance patient safety and quality of care, it is recommended that medical institutions focus on training programs to improve nurses' knowledge and attitude towards preventing MDRPI.
