Outcomes of Traditional and Enhanced Gonorrhea Partner Services in the Strengthening the US Response to Resistant Gonorrhea Project, 2017 to 2019.

Abstract

The Centers for Disease Control and Prevention implemented Strengthening the US Response to Resistant Gonorrhea (SURRG) to build local detection and response capacity and evaluate responses to antibiotic-resistant gonorrhea outbreaks, including partner services for gonorrhea. We evaluated outcomes of traditional partner services conducted under SURRG, which involved (1) counseling index patients and eliciting sexual partners; (2) interviewing, testing, and treating partners; and (3) providing partner services to partners newly diagnosed with gonorrhea. We also evaluated outcomes of enhanced partner services, which additionally involved interviewing and testing partners of persons who tested negative, and social contacts of index patients and partners. We analyzed partner services investigation data from 8 jurisdictions participating in SURRG from 2017 to 2019. We summed total index patients, partners from traditional partner services, and partners and contacts from enhanced partner services, and calculated partner services outcomes among partners and contacts. We also visualized sexual networks from partner services data. Of 1242 index patients identified, 506 named at least 1 sexual partner. Traditional partner services yielded 1088 sexual partners, and 105 were newly diagnosed with gonorrhea. Enhanced partner services yielded an additional 59 sexual partners and 52 social contacts. Of those partners and contacts, 3 were newly diagnosed with gonorrhea. Network visualization revealed sparse networks with few complex partnership clusters. Traditional partner services for gonorrhea may be useful for eliciting, notifying, and diagnosing partners of index patients in an outbreak setting. Enhanced partner services are unlikely to be effective for eliciting, notifying, and diagnosing a substantial number of additional people.
