Purpose. The study aims to determine the correlation between management care perception and the professional quality of life of intensive care unit (ICU) nurses in China and examine the influencing factors. Design and Methods. A cross-sectional descriptive study was conducted with 486 ICU nurses (response rate: 97.2%) from five tertiary hospitals in China from 1 January to 31 July, 2022, by convenience sampling. Data were collected through the general information questionnaire, the management care assessment scale, and the professional quality of life scale. Findings. The score of management care perception of ICU nurses was (132.24 ± 28.04), and the scores of compassion satisfactory, compassion fatigue, and burnout of professional quality of life were (37.54 ± 7.73), (20.80 ± 6.49), and (17.79 ± 5.14), respectively. Multiple linear regression analysis showed that age and the total score of managed care were positively correlated with the score of compassion satisfaction dimension (β = 1.62, 0.19) and that the total score of perceived management care was negatively correlated with the score of compassion fatigue and job burnout (β = −0.04, −0.07). ICU nurses’ perceived level of managerial care was at a moderate level. The younger the nurse and the less managerial care they perceived, the lower their job satisfaction and the greater the burnout. Practice Implications. ICU nurses’ perceptions of management care and professional quality of life are at a medium level, and a significant correlation exists between them. Therefore, measures to improve the professional quality of life should be taken. Nursing administrators are obliged to actively create a good atmosphere of management care, reduce the job burnout of ICU nurses, improve their professional quality of life, optimise the quality of nursing service, and stabilise the nursing team.

The ability of knowledge, attitude, and practice of intensive care unit (ICU) nurses to perform medical device‐related pressure injuries (MDRPIs) can affect the incidence of MDRPI in ICU patients. Therefore, in order to improve ICU nurses' understanding and nursing ability of MDRPIs, we investigated the non‐linear relationship (synergistic and superimposed relationships) between the factors influencing ICU nurses' ability of knowledge, attitude, and practice. A Clinical Nurses' Knowledge, Attitude, and Practice Questionnaire for the Prevention of MDRPI in Critically Ill Patients was administered to 322 ICU nurses from tertiary hospitals in China from January 1, 2022 to June 31, 2022. After the questionnaire was distributed, the data were collected and sorted out, and the corresponding statistical analysis and modelling software was used to analyse the data. IBM SPSS 25.0 software was used to conduct Single factor analysis and Logistic regression analysis on the data, so as to screen the statistically significant influencing factors. IBM SPSS Modeler18.0 software was used to construct a decision tree model of the factors influencing MDRPI knowledge, attitude, and practice of ICU nurses, and ROC curves were plotted to analyse the accuracy of the model. The results showed that the overall passing rate of ICU nurses' knowledge, attitude, and practice score was 72%. The statistically significant predictor variables ranked in importance were education background (0.35), training (0.31), years of working (0.24), and professional title (0.10). AUC = 0.718, model prediction performance is good. There is a synergistic and superimposed relationship between high education background, attended training, high years of working and high professional title. Nurses with the above factors have strong MDRPI knowledge, attitude, and practice ability. Therefore, nursing managers can develop a reasonable and effective scheduling system and MDRPI training program based on the study results. The ultimate goal is to improve the ability of ICU nurses to know and act on MDRPI and to reduce the incidence of MDRPI in ICU patients.
