Abstract:
Objective:To investigate the current status of intensive care unit-acquired weakness (ICU-AW) assessment, analyze the assessment barriers, and to provide reference to improve ICU-AW assessment.Methods:A convenient sampling cross-sectional survey was conducted. First, an interview outline which based on related domestic and international literatures and combining with the research purpose of this study were designed. Thirteen medical personnel (8 ICU nurses, 3 ICU doctors, 1 respiratory therapist and 1 physiotherapist) who worked in the intensive care unit (ICU) of the First Hospital of Lanzhou University were enrolled with convenience sampling method to interview. Second, the topics were comprehensively analyzed and extracted, and then a questionnaire was constructed, and the reliability and validity was assessed. Finally, the questionnaire survey including the general situation of ICU medical staffs, the current practices of ICU-AW and influencing factors was implemented in China.Results:The retest reliability was 0.92 and expert validity was 0.96 of the questionnaire. There were 3 563 respondents in 31 provinces, municipalities and autonomous regions which eliminated 357 unqualified questionnaires, including 173 respondents from neonatal or pediatric ICU, 89 respondents whose working time was less than 6 months, and 95 invalid respondents, and then there were finally 3 206 valid questionnaires and the response rate were 90.0%. Those 3 206 respondents included 616 doctors (19.2%), 2 371 nurses (74.0%), 129 respiratory therapists (4.0%), 51 physiotherapist (1.6%) and 39 dietitians (1.2%). The mean age was (30.7±6.3) years old. Most of them had bachelor's degree (65.9%), master and above was 14.1%. Associate senior physician and above was 8.0%; ICU working time was (5.94±4.50) years. In clinical practice, only 26.5% of the ICU medical staffs confirmed that they had treated or taken care for ICU-AW patients; 52.9% of medical staffs evaluated ICU-AW only based on clinical experience, and only 12.3% used ICU-AW assessment tools. The majority of respondents believed that ICU-AW knowledge training should be performed (81.8%), ICU-AW assessment should be as important as other complications (pressure sore, infected ventilator associated pneumonia, etc., 75.1%), and ICU-AW assessment should be part of daily treatment and care activities (61.2%). However, only 10.2% of respondents had received ICU-AW related knowledge training, and 42.7% respondents believed that their ICU-AW related knowledge could not meet clinical needs. Only 18.7% respondents would actively assess whether patients suffered from ICU-AW or not, and 42.3% respondents thought that ICU-AW should be assessed every day, and the assessment tools were also inconsistent. There were 44.0% respondents considered the Medical Research Council Muscle score (MRC-score) scale was the optimal tool for diagnosing ICU-AW, the following were neuro-electrophysiological examination (17.2%) and manual muscle strength (MMT, 11.1%). The main cause of the ICU-AW assessment barriers was the lack of ICU-AW related knowledge (88.1%), and the following were lack of ICU-AW assessment guidelines (76.5%), patients' cognitive impairment or limited understanding ability (84.6%), unable to cooperate with the assessment due to critical illness (83.0%), and inadequate attention to ICU-AW assessment by the department (77.5%).Conclusion:The current status of ICU-AW assessment were unsatisfying in China, and the main barriers were lack of skills and knowledge.
