Registered nurses working in inpatient departments are responsible for caring for patients receiving overnight treatment in the hospital. This role demands professional skills and the ability to cope with uncertain working hours and conditions. Therefore, assessing and maintaining the work ability of nurses in inpatient departments is crucial. The objective of this study was to evaluate the level of work ability and assess the factors associated with it among nurses working in the inpatient departments of a university hospital in Thailand. The study was a cross-sectional study. Information on nurses was collected through a questionnaire survey. Exposure factors, including heat, light, and noise, were measured using standard methods. Cluster random sampling was employed to select the study population. Descriptive statistics and ordinal logistic regression analyses were conducted. A total of 374 registered nurses working in the inpatient departments participated in the study. The average work ability index was 32.8 points out of 49 points, and 78.8% of participants were categorized as having a moderate level of work ability. The factors associated with better work ability were age 45 years old and older (ORadj = 3.73, 95%CI = 1.31 - 10.86), an average monthly income of more than 50,000 baht (ORadj = 5.31, 95%CI = 1.72 - 16.87), and working beyond one's self-capacity (ORadj = 0.38, 95%CI = 0.20 - 0.71). To maintain the work ability of registered nurses, the hospital administrative team should consider and adjust the workforce of registered nurses to ensure the proper distribution of the workload. Additionally, policymakers should pay more attention to newly registered nurses in order to maintain and promote their work ability, enabling them to continue working effectively and happily.
