<p><strong>PURPOSE: </strong>In 2002, the Centers for Disease Control and Prevention (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 objectives were to estimate trends in PID diagnosis among adolescent emergency department (ED) patients before and after the revised CDC definition and to identify factors associated with PID diagnoses.</p>
<p><strong>METHODS: </strong>We performed a retrospective repeated cross-sectional study using the National Hospital Ambulatory Medical Care Survey from 2000 to 2009 of ED visits by 14- to 21-year-old females. We calculated national estimates of PID rates and performed multivariable logistic regression analyses and tests of trends.</p>
<p><strong>RESULTS: </strong>During 2000-2009, of the 77 million female adolescent ED visits, there were an estimated 704,882 (95% confidence interval [CI], 571,807-837,957) cases of PID. After the revised criteria, PID diagnosis declined from 5.4 cases per 1,000 United States adolescent females to 3.9 cases per 1,000 (p = .03). In a multivariable model, age ≥17 years (odds ratio, 2.14; 95% CI, 1.25-3.64) and black race (odds ratio, 2.04; 95% CI, 1.36-3.07) were associated with PID diagnosis.</p>
<p><strong>CONCLUSIONS: </strong>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.</p>
