To assess hysterectomy rates, type of hysterectomy, and other factors associated within the United States from 1990-1997.

A descriptive statistical analysis of national discharge data was undertaken. Data from the nationwide Inpatient Sample of the Healthcare Cost and Utilization Project (from which national estimates are generated based on a 20% stratified sample of US community hospitals) were used for the years 1990-1997. All women who underwent hysterectomy were identified using International Classification of Diseases, 9th Revision, Clinical Modification, procedure codes. Outcome measures included rate, type of hysterectomy, age of patients, length of stay, total hospital charges, and diagnostic categories.
