  • CHIA examines provider price variation in the commercial health insurance market by illustrating differences in prices paid to providers for the same set of services. CHIA also compares provider payments across commercial payers, while standardizing for differences in patient acuity, the types of services providers deliver to patients, and the different product types that payers offer their members.

  • CHIA reports on trends in hospital performance and utilization via two new publications: Hospital Profiles and the Patient Origins Map. Hospital Profiles provides information on hospital services, payer mix, utilization, and financial performance. The Patient Origins Map illustrates the distribution of inpatient discharges for each Massachusetts hospital system.
