BackgroundPhysical restraint (PR) is widespread use among older adults in long-term care (LTC) facilities, which has negative effects on older adults’ health and quality of care. Considering that research on PR use in Chinese LTC facilities is rare, assessment of nursing staff’s knowledge, attitude, and practice (KAP) is a prerequisite before minimized PR program and staff training project development.PurposeThis study aimed at determining the differentiation of levels and factors of KAP toward PR use between nurses and nursing assistants in LTC facilities.MethodsA cross-sectional study was conducted in six Chinese LTC facilities from November to December in 2019 and May to June in 2020. A total of 316 nursing staff, comprising 69 nurses and 247 nursing assistants were investigated using the Chinese version of the Staff Knowledge, Attitudes and Practices Questionnaire regarding PR. One-way analysis of variance, chi-squared test, Welch test, the Mann–Whitney U-test, and multiple linear regression were performed for data analysis.ResultsMean scores of overall knowledge, attitude, and practice were 5.90±2.27, 31.97±3.01, 30.89±4.82, respectively. PR knowledge and practice of nurses were significantly higher than that of nursing assistants (all P<0.001), whereas PR attitude with no significant difference (P=0.084). In-school training, in-job training, and knowledge on PR significantly affected PR practice of nurses and nursing assistants. Further, nursing assistants’ practice was also significantly predicted by education (β=0.131, P=0.019), age (β=−0.140, P=0.034), monthly income (β=−0.184, P=0.002), and attitude (β=0.130, P=0.030). In-job training (β=0.283, P<0.001), age (β=−0.164, P=0.021), and knowledge (β=0.292, P<0.001) significantly affected nursing assistants’ attitude, while their knowledge was influenced by monthly income (β=0.153, P=0.019) and work years in LTC (β=0.343, P<0.001).ConclusionSpecific knowledge deficits, negative fields of attitude, and practice were dissimilar between nurses and nursing assistants. The targeted and stratified PR education approaches were suggested to prompt their KAP.
