Supracervical and total abdominal hysterectomy trends in New York State: 1990-1996.

To describe practice trends for total abdominal hysterectomy (TAH) and supracervical abdominal hysterectomy (SCH) in New York State and to identify fiscal features associated with these two operations, all inpatient discharges for TAH and SCH performed for benign indications from 1990 to 1996 were reviewed using the Statewide Planning and Resource Cooperative System, a centralized data reporting system. For each year examined, the number of TAHs and SCHs performed, the procedure rates adjusted for the total New York State female population, and the per diem charge (calculated from mean institutional charge as a function of average length of stay) were evaluated. While the TAH rate declined in New York State, from 34.0 in 1990 to 28.4 in 1996 (P = .01), the SCH rate increased nearly five-fold during the same period, from 0.62 to 3.07 (P = .0003). Patients tended to be discharged later following SCH than for TAH, although by 1996, the LOS for both operations was equivalent. The per diem institutional charge for SCH was consistently higher than for TAH in each year studied. The changes in charge and relative frequency of TAH and SCH in New York State invite further study to describe these trends more fully.
