Data collection was performed between June 19 and June 27, 2023. The study sampleconsisted of 1,215 hospitals, and we analyzed the data using SAS 9.4 and Mplus 8 software.
Results: The averagenumbers of patients per registered nurse, certified nursing assistant, and nursing staff, including both registerednurses and certified nursing assistant, was 10.00, 7.43, and 4.00, respectively. Path analysis revealed that thenumber of patients per registered nurse had direct effects on improvements in activities of daily living and indirecteffects on indwelling catheterization, pressure ulcer improvement, and weight loss. The number of patients percertified nursing assistant had direct effects on new pressure ulcer development and pressure ulcer improvement,with no indirect effects.
