A new Resource Utilization Groups (RUG-III) system classifies nursing home residents, improving cost prediction and care assessment. This system enhances accuracy for high-tech care and cognitive needs, aiding payment and management.

Area of Science:

  • Gerontology
  • Health Services Research
  • Nursing Home Administration

Background:

  • Accurate case-mix classification is crucial for fair nursing home reimbursement.
  • Previous systems had limitations in explaining cost variations and identifying complex resident needs.

Purpose of the Study:

  • To develop and validate the Resource Utilization Groups, Version III (RUG-III) case-mix classification system.
  • To improve the explanation of cost variance and clinical validity compared to prior versions.

Main Methods:

  • Utilized data from 7,658 nursing home residents across seven states.
  • Assessed resident characteristics using Minimum Data Set items.
  • Measured nursing and therapy staff time to determine resource utilization.

Main Results:

  • The RUG-III system, with 44 groups, explained 55.5% of per diem cost variance.
  • Identified high-tech procedures and cognitive impairments more effectively.
  • Demonstrated a nine-fold range in mean resource use across case-mix groups.

Conclusions:

  • RUG-III offers improved clinical validity and payment incentives for nursing homes.
  • The system is suitable for payment, management, staffing, and quality assurance.
  • Implementation is underway in multiple states, including federal demonstrations.
