Objectives: To estimate trends over time in inpatient obstetric and gynecologic surgical procedures, and to estimate commonly performed obstetric and gynecologic surgical procedures across a woman's lifespan. Methods: Data were collected for procedures in adult women from 1979 to 2006 using the National Hospital Discharge Survey, a federal discharge dataset of U.S. inpatient hospitals, including patient and hospital demographics and International Classification of Diseases, 9th Revision, Clinical Modification procedure codes for adult women from 1979 to 2006. Age-adjusted rates per 1,000 women were created using 1990 U.S. Census data. Procedural trends over time were assessed. Results: More than 137 million obstetric and gynecologic procedures were performed, comprising 26.5% of surgical procedures for adult women. Sixty-four percent were only obstetric and 29% were only gynecologic, with 7% of women undergoing both obstetric and gynecologic procedures during the same hospitalization. Obstetric and gynecologic procedures decreased from approximately 5,351,000 in 1979 to 4,949,000 in 2006. Both operative vaginal delivery and episiotomy rates decreased, whereas spontaneous vaginal delivery and cesarean delivery rates increased. All gynecologic procedure rates decreased during the study period, with the exception of incontinence procedures, which increased. Common procedures by age group differed across a woman's lifetime. Conclusion: Inpatient obstetric and gynecologic procedures rates decreased from 1979 to 2006. Inpatient obstetric and gynecologic procedure rates are decreasing over time but still comprise a large proportion of inpatient surgical procedures for U.S. women.
