    Participants were approximately 1.2 million beneficiaries of the Civilian Health and Medical Program of Uniformed Services (CHAMPUS) residing within either 11 military hospital catchment areas in California and Hawaii ( « demonstration areas ») or 11 matched control areas in other parts of the United States.

    Under CRI, participants were offered a choice of the standard CHAMPUS indemnity plan, a Preferred Provider Organization-type plan, or a network-model Health Maintenance Organization plan.

    Beneficiaries were encouraged to use alternatives to the ED for nonemergency conditions.

    Visits to civilian EDs during two 12-month periods, before and after institution of CRI, were compared.


    Under CRI, the number of CHAMPUS ED visits decreased by approximately 40% relative to the control, and allowed charges fell by almost 50%. Relative reductions in ED use under CRI were seen among both frequent and infrequent users of the ED.

    ED case-mix severity increased modestly relative to control (+3.5% versus+9%). ED use among patients with diabetes, hypertension, and asthma fell sharply in the demonstration areas (by 14% to 41%) but rose in control areas (by 4% to 9%). (...)
