This article reviews and analyzes CHAMPUS (Civilian Health and Medical Program of the Uniformed Service) inpatient data from 1981 to 1991. Utilization data are presented by state, year, and profession for inpatient visits. There has been a moderate but progressive growth in the proportion of inpatient visits provided by psychologists over these years, from 3.3% to 19.4%, nationally. In terms of beneficiaries receiving some psychological services, the proportion increased from 7.2% to 26.5%. Visit level in 1991 was highest in Texas at 30.5% and least in Georgia at 12.7% among the 9 states detailed. Psychiatry has seen a 20% drop in the proportion of inpatient visits it has rendered over these years, and fewer psychiatrists provided CHAMPUS services in 1991 than in 1981. These data reflect the fact that the private practice of psychology in hospitals has gained increasing recognition.
