Hospitalizations for pelvic inflammatory disease in Texas. A population-based analysis.

Objective: To calculate pelvic inflammatory disease (PID) hospitalization rates for Texas and identify risk factors for prolonged length of stay (PLOS) among women hospitalized for PID throughout Texas and discharged during a 2-year period.

Study Design: A cross-sectional study of 6,421 women discharged from Texas hospitals in 2004 and 2005 with a diagnosis of PID was conducted. Data for 2004 and 2005 were obtained from the Texas Department of State Health Services. Diagnoses had been coded using the ICD-9-CM. Odds ratios for PLOS adjusted for age, insurance status, race, diabetes, hypertension, and receipt of oophorectomy during hospitalization were calculated.

Results: Blacks experienced the highest unadjusted hospitalization and were more likely than whites to have PLOS. Presence of diabetes was the strongest risk factor for PLOS. Undergoing an oophorectomy during the hospital stay was not significantly correlated with PLOS.

Conclusion: This unique statewide study found that among a large group of women hospitalized for PID, blacks were significantly more likely than whites to have PLOS. The presence of diabetes was the strongest factor associated with a PLOS.
