*3.4.1 Records*

The daily census report, bed occupancy, and patient needs classification using the Slovenian patient classification system [39] were collected from the hospital every day. Data from nursing schedules and hospitalized patient numbers allowed the calculation of the number of patients per nursing staff (registered nurse, nursing technician), staff hours per patient day (registered nurse, nursing technician), and the proportion of graduate nursing staff hours. The principal investigator of the study collected data daily after the study approval and by contacting the chief nurse.
