Hospitalizations for Benign Gynecological Condition in California, 1992-2004

Principal Investigator: Associate Professor L. Elaine Waetjen, M.D.


This is a secondary analysis of existing public datasets, the California Patient Discharge Database (CPDD) and the California Census. Our CPDD data includes ICD-9 diagnosis and procedure codes for hospitalizations of all females over the age of 12 in California between 1991 and 2004 and was obtained through a formal request from the Office of Statewide Health Planning and Development (OSHPD).


Our specific aims for this project are as follows:

  1. To describe the prevalence, incidence and time-trends in hospitalizations and inpatient procedures for five benign gynecologic conditions by age, racial/ethnic category, county and rural or urban community between 1991 and 2004 in California. These conditions will include stress urinary incontinence, pelvic organ prolapse, uterine fibroids, pelvic inflammatory disease, and ovarian hyperstimulation.
  2. To assess utilization of resources and complications for these gynecologic conditions and their associated inpatient procedures including length of hospital stay, morbidity and mortality, and hospital readmissions within 90 days by age, racial/ethnic category and rural/urban community.
