This study explored the impact of skill mix model changes on patient outcomes in a critical care environment, specifically, a respiratory care centre based in a southern Taiwan medical centre. It identified that the cost of ventilator-dependent patients in Taiwan in 1999 was 3.5 billion New Taiwan dollars, equivalent to US$ 121 million. In this context, controlling the costs of healthcare while maintaining quality care became critical. This research examined two skill mix staffing models, a mixed registered nurse (RN) and nursing aid model and a 100% RN model, and their impact on patient outcomes. Patient outcomes were pressure ulcers, respiratory and urinary tract infections, blood stream infections, days of hospitalisation and ventilator weaning.
