Poster Session I: Surveillance & Epidemiology - Other Pathogens

(P52) REPORTED CASES OF PELVIC INFLAMMATORY DISEASE, NORTH CAROLINA 2013-2023

Tuesday, September 17, 2024
4:15 PM - 5:15 PM EST
Background:
North Carolina (NC) requires Pelvic Inflammatory Disease (PID) cases be reported to the health department via a case report form (CRF) that is used for all communicable diseases. However, bias may exist in PID reporting among providers.

Methods:
We assessed demographics, symptoms, and concurrent chlamydia/gonorrhea (CT/GC) infection (≤30 days of PID diagnosis) for all PID cases reported to the NC health department between 2013 and 2023. We also compared proportions of case characteristics by reporting facility.

Results:
During 2013-2023, 2,991 cases of PID were reported in NC. The yearly number of reported cases declined over time, from a high of 498 cases in 2013 to a low of 119 cases in 2021. Over one-third (N=1,091) of cases were reported from one hospital system (high-volume facility); 94% (N=1,030) of these cases were diagnosed in the emergency department. Among the 1,900 cases diagnosed in other facilities, half were reported from emergency departments (N=898) and 19% (N=367) were reported from STD Clinics. Cases were most frequently 20-29 years old (51%; N=1,520),  Black (51%; N=1,518), and non-Hispanic (75%; N=2,237). PID symptoms were reported for 2,816 (95%) cases. Demographics and report of symptoms did not vary between the high-volume facility and other facilities. Cervical motion tenderness was the most commonly reported symptom from the high-volume facility while a majority (69%) of cases from other facilities did not have specific symptoms documented. Overall, 32% of PID cases were concurrently infected with CT/GC; only 20% of cases reported from the high-volume facility were concurrently infected with CT/GC. The yearly CT/GC concurrent infection proportion varied between 25% and 42% between 2013 and 2023.

Conclusion:
Providers do not uniformly report PID, limiting the generalizability of case reports. Incorporating additional questions specific to PID epidemiology and etiology to CRFs could improve the utility of case-based surveillance for PID.
