Evaluation: Utilization Management

DBHS trends several utilization indicators including enrolled patient days, user member months, enrolled patient days/1000 for four levels of care (inpatient acute, Arizona State Hospital, residential treatment, and psychiatric health facility), readmission rates within 30 days, cost of service provision, value of service provision (functional change scores and the average cost to attain the positive or negative change effect), average length of stay, and number of admissions and discharges. The data is trended quarterly. Statistical Process Control Charts track the utilization indicators in order to detect normal variation in utilization versus outliers.
