Impact of Nurses' Knowledge, Self‐Efficacy and Clinical Reasoning Competency on Difficulties in Caring for Patients With Delirium in the Intensive Care Unit: A Cross‐Sectional Study
Abstract
ABSTRACT Aim To examine the impact of critical care nurses' delirium knowledge, self‐efficacy and clinical reasoning competency on delirium care difficulties based on the information–motivation–behavioural (IMB) skills model from a behavioural perspective. Design Cross‐sectional study. Methods A total of 440 critical care nurses from five hospitals in China were selected using convenience sampling and invited to complete an online questionnaire for measurement. Data were collected in November 2024 and analysed using SPSS/AMOS with descriptive statistics, Pearson's correlation coefficient and multiple regression. Structural equation modelling was constructed to test the hypothesised relationships among the variables, with bootstrapping to assess mediation effects. Results The level of delirium care difficulties was moderated. Delirium care difficulties were negatively correlated with delirium knowledge, self‐efficacy and clinical reasoning competency. Clinical reasoning competency partly mediated delirium knowledge and self‐efficacy with regard to delirium care difficulties. Conclusion Delirium knowledge, self‐efficacy and clinical reasoning competency are essential for improving critical care nurses' delirium care competencies. The role of clinical reasoning competency in the relationship between the other two variables and delirium care difficulties was highlighted. Establishing multifaceted innovative delirium education programmes, emphasising individuals' sense of…
