Objective
In 2002 the CDC broadened the pelvic inflammatory disease (PID) diagnostic criteria to increase detection and prevent serious sequelae of untreated PID. The impact of this change on PID detection is unknown. Our objective was to estimate trends in PID diagnosis among adolescent emergency department (ED) patients before and after the revised CDC definition and identify factors associated with PID diagnoses.
Methods
We performed a retrospective repeated cross-sectional study using the National Hospital Ambulatory Medical Care Survey from 2000–2009 of ED visits by 14 to 21 year old females. National estimates of PID rates were calculated. Multivariable logistic regression analyses and tests of trends were performed.
Results
During 2000–2009, of the 77 million female adolescent ED visits, there were an estimated 704,882 (95% CI 571,807, 837,957) cases of PID. Following the revised criteria, PID diagnosis declined from 5.4 cases per 1000 U.S. adolescent females to 3.9 cases per 1000 (p=0.03). In a multivariable model, age ≥17 years (OR 2.14, 95% CI 1.25, 3.64) and Black race (OR 2.04, 95% CI 1.36, 3.07) were associated with PID diagnosis
Conclusions
Despite broadened CDC diagnostic criteria, PID diagnoses did not increase over time. This raises concern about awareness and incorporation of the new guidelines into clinical practice.
