Using the outcome-based quality improvement model and OASIS to improve HMO patients' outcomes. Outcome Assessment and Information Set.

The study purpose was to determine if use of the Outcome-Based Quality Improvement (OBQI) model, including a subset of the outcome Assessment and Information Set (OASIS), enhanced outcomes for health maintenance organization (HMO) patients referred for care to six contracted home health agencies (HHAs). After four quarters of data-driven quality improvement activities, the improvement scores of the patients were not changed significantly from the baseline period. Stabilization scores increased significantly for two of the five outcome measures. Use of OASIS and the OBQI model for HMO patients referred to multiple HHAs requires that contracted HHAs share outcome results and quality improvement conclusions.
