Insights
Hospitalizations for pelvic inflammatory disease (PID) and tuboovarian abscesses declined in California from 1991 to 2001. Black women aged 20-39 experienced the highest PID hospitalization rates during this period.
Area of Science:
- Reproductive Health
- Infectious Diseases
- Public Health Surveillance
Background:
- Pelvic inflammatory disease (PID) and tuboovarian abscess (TOA) are significant gynecological infections.
- Understanding hospitalization trends and demographic disparities is crucial for targeted interventions.
Purpose of the Study:
- To analyze demographic characteristics and hospitalization trends for PID and TOA in California between 1991 and 2001.
- To identify specific age and racial/ethnic groups disproportionately affected by PID hospitalizations.
Main Methods:
- Utilized the California Patient Discharge Database and International Classification of Diseases, 9th Revision, Clinical Modification codes.
- Analyzed hospitalization rates by age and race/ethnicity using census data.
- Estimated procedural associations, length of stay, readmission rates, and mortality.
Main Results:
- PID hospitalization rates decreased by 61.5% and TOA rates by 33.3% from 1991 to 2001.
- Hospitalization rates for PID were highest among women aged 20-39.
- Black women aged 20-39 exhibited the highest PID hospitalization rates; hysterectomy rates were lowest in this group.
Conclusions:
- A significant decline in PID hospitalizations was observed in California between 1991 and 2001.
- Targeted public health efforts may be needed for Black women aged 20-39 due to persistently high PID hospitalization rates.
Objective:
To describe the demographic characteristics of and procedures for patients hospitalized for pelvic inflammatory disease (PID) and tuboovarian abscess in California from 1991 to 2001.
Methods:
We used the International Classification of Diseases, 9th Revision, Clinical Modification, diagnostic and procedural codes in the California Patient Discharge Database and census data to calculate hospitalization rates for PID and tuboovarian abscess by age and race/ethnicity. We estimated the proportion of PID and tuboovarian abscess hospitalizations associated with procedures and estimated average length of hospital stay, readmission rates, and mortality.
Results:
From 1991 to 2001, the California hospitalization rate for PID decreased by 61.5% (from 2.6 to 1.0 per 10,000 women). Tuboovarian abscess hospitalization rates declined by 33.3% during the same time period (from 0.6 to 0.4). Pelvic inflammatory disease hospitalization rates were highest among 20-39 year olds compared with other age categories. Black women aged 20-39 had the highest PID hospitalization rates compared with other racial/ethnic groups. The proportion of hospitalizations associated with hysterectomy was lowest for blacks.
Conclusion:
In California, the hospitalization rate for PID has declined between 1991 and 2001. Black women, 20-39 years of age, had the highest PID hospitalization rates.
