Ability to Recontact Sex Partners and Partner Treatment Success Among Young Heterosexual Black Men With Chlamydia

Purpose: Patient-delivered partner therapy (PDPT) allows index patients who test positive for Chlamydia trachomatis (Ct) to provide treatment to partners directly. PDPT is contingent upon an index being able to contact their partner. The aims of this study were to assess factors related to being able to contact a partner and being able to successfully deliver their treatment.

Methods: Participants were Black men who have sex with women aged 15-26 enrolled in a community Ct screening/treatment program in New Orleans, LA who tested positive for Ct and completed a computer-assisted survey. Factors associated with the index's ability to contact their recent sex partner(s) and to successfully deliver PDPT to his partner(s) were compared by characteristics of the relationship.

Results: Of 104 young men who tested positive for Ct, the median age was 20.3 years and information was reported on 184 female partners, of whom 143 (77.7%) were deemed contactable by the index. Only the index wanting to have sex with the partner again was significantly associated with their ability to contact the partner (odds ratio [OR] 5.38, 95% confidence interval [CI] 2.18, 13.23). Only 72/184 (39.1%) partners received PDPT. The index being interested in sex with partner again (OR 2.54, 95% CI 1.23-5.27) was associated with greater odds of successful PDPT delivery whereas if index believed their partner had other partners, successful PDPT was less likely (OR 0.51, 95% CI 0.26-0.99). There was low agreement between an index's ability to contact their partner and the delivery of PDPT (kappa = 0.04 [-0.062, 0.143).

Discussion: Asking patients if they can recontact prior sexual parters may be insufficient to ensure that their partners receive PDPT.
