Background:
resource use by different types of patients is of increasing interest to health care services all over the world. Case-mix systems that group together individuals with similar patterns of resource use have been developed to address these questions. Resource Utilization Groups version III (RUG-III) was developed in the USA to address the issue in the care of elderly people and has been validated in a number of countries.
Method:
this paper synthesizes the results of RUG-III validation studies performed in the USA, Japan, Spain, Sweden and England and Wales, showing the consistency of the system in spite of different skill-mix and total time spent with patients. Data from the validation studies of five countries were compared. Percentage of time given by trained nurses and mean nursing time per patient was compared overall and between selected RUG-III groups.
Results:
mean time per patient ranged from 84.4 min per day in Japan, to 155.6 min in England and Wales. Trained nurse time ranged from 7.5% of total time in the USA to 53.2% of total time in England and Wales. The inter-group relationship was very similar in all countries. The RUG-III system appears robust in a wide variety of settings and countries. Future research should address the relationship between skill-mix and total time spent with patients with respect to outcome and quality of care.

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...
