Abstract
To investigate ICU nurses' knowledge level with regard to device-related pressure injuries in northern, central, and southern China and analyse its influencing factors. A total of 261 ICU nurses participated in this cross-sectional survey A convenience sampling method was used to select ICU nurses as respondents from one hospital in each of the six cities of Taiyuan, Wuhan, Xianning, Guangzhou, Foshan, and Huizhou. Data were collected using the MDRPI Knowledge Questionnaire. The questionnaire was developed by the investigators based on a summary of evidence of MDRPI, which has been reviewed and validated by experts. The obtained data were analysed using SPSS software. The average rate of the correct response about MDRPI was 60.54% (15.74 ± 2.90). The lowest percentage of correct responses was on the "concept and staging" dimension rated 28% (0.56 ± 0.67). The "skin assessment" dimension rated 39.2% (1.57 ± 0.84). Multiple linear regression analysis showed that the factors influencing the MDRPI knowledge of ICU nurses included hospital grade, the highest educational attainment, whether or not they had wound care certification, when they last attended MDRPI training or lectures, and whether or not they had attended MDRPI training or lectures. The level of knowledge of nurses about MDRPI was insufficient. Training of ICU nurses on MDRPI should be emphasised at the institutional level. MDRPI training contents should be based on clinical evidence and updated timely. There is a need to focus on the training of wound care certification and education.
