An indicator calculated by taking the total number of inpatient and/or outpatient admissions from a specific group, e.g., employer group, HMO population at risk, for a specific period of time (usually one year), dividing it by the average number of covered members in that group during the same period, and multiplying the result by 1,000. This indicator can be calculated for behavioral health or any disease in the aggregate and by modality of treatment, e.g., inpatient, residential, and partial hospitalization, etc.
