ABSTRACT
PURPOSE: This study was done to evaluate the adequacy of nurse staffing in integrated nursing care. METHODS: Statistical data on integrated nursing care from the National Health Insurance Corporation was used in this study. We extracted hospital data and patient data related to patient needs for nursing care. We analyzed the differences in patient needs by staffing level of each type of medical institution. RESULTS: Approximately 70% of medical institutions provided nursing care by the mid level of nurse staffing, which was 1:6, 1:10 and 1:12 in the tertiary hospital, general hospital and semi-hospital, respectively. The patients' characteristics were significantly different by hospital type. Especially, the distribution of the main diagnosis was completely different between the tertiary hospital and semi-hospital. In the tertiary hospital, the patient needs measured by severity and activities of daily living dependency were higher at higher staffing level than at lower staffing level. However, the nurse staffing was less relevant to the patient needs in the general hospital and semi-hospital. CONCLUSION: To provide high-quality nursing care, accurate workload forecasting is required at the start, and then the standard nurse staffing level can established based on workload forecasting.
