Improving chlamydia risk screening by using the CDC's 5 Ps approach to sexual health history

BACKGROUND

Chlamydia trachomatis is infecting service members (SMs) at a rate of two to three times that of the U.S. population. Currently, the military only screens female SMs under the age of 25 years, leaving many at-risk males to go undetected leading to further transmission.

LOCAL PROBLEM

Service members are not routinely assessed for high-risk sexual activities, leading to increased chlamydia rate in Fort Bragg. At the primary care project site, screening was only done per HEDIS measure leading to only 5% STI positivity rate. The purpose of this project was to identify and screen SMs who are at high risk for chlamydia using the CDC's 5 Ps approach.

METHODS

This project took place at a large primary care clinic that only cared for active-duty soldiers over a 3-month period.

INTERVENTIONS

The CDC's 5 Ps questionnaire was administered to SMs 30 years and younger during routine appointments. The SMs deemed high risk from the questionnaire were screened using urine G/C NAAT testing.

RESULTS

Four hundred forty-nine SMs were assessed using the CDC's 5 Ps approach. The questionnaire identified 91 SMs (20%) at higher risk for STIs. Of the 45 urine samples submitted, six were positive for STIs. Of the six positive cases, five were male. Targeted screening resulted in 13.3% positive rate compared with the 5% in the current practice.

CONCLUSION

The result suggests that targeted screening of young males and females can identify high-risk sexual behaviors leading to increased findings of asymptomatic chlamydia carriers, ultimately leading to decreased chlamydia incidence.
