Abstract

Intensive care unit (ICU)-acquired weakness (ICU-AW) is a common neuromuscular complication among patients in the ICU. The short-term consequences include muscle weakness, prolonged mechanical ventilation, and prolonged hospitalization, and the long-term consequences include increased patient comorbidities, increased hospitalization costs, and a higher disease burden. However, few studies have examined ICU nurses' KAP regarding ICU-acquired weakness, particularly in the context of Chinese tertiary hospitals. Therefore, it is important to understand the level of knowledge, attitudes, and practices of ICU-AW among ICU nurses.
This is an exploratory cross-sectional study conducted without prespecified directional hypotheses. Through this study, we aim to understand the knowledge, attitudes, and practices of ICU nurses with respect to ICU-AW. The findings will provide a reference for hospitals to manage or prevent ICU-AW.
From January 2023 to February 2023, a survey involving 208 ICU nurses (recruited through convenience sampling) in Shiyan area was conducted. The survey included a general information questionnaire and the ICU-AW Knowledge and Attitudes Practices Questionnaire.
The mean scores for knowledge, attitude, and practice were 32.29 ± 4.50, 34.64 ± 4.81, and 30.41 ± 7.47, respectively. The multiple linear regression showed that hospital level and nurses' marital status independently related to the knowledge and practices of ICU nurses around ICU-AW (both P < 0.05). The linear regression equation was as follows: Y = 91.736 - 6.373 × hospital level - 4.119 × marital status (F = 11.349, R² = 0.101, adjusted R² = 0.092).
The overall knowledge and practice levels of ICU nurses with respect to ICU-AW was moderate, and was associated with hospital level and marital status. The findings of this exploratory study provide preliminary evidence and testable hypotheses for subsequent prospective or interventional studies.
