RESUMEN
Assisted partner notification programs represent one strategy for targeted HIV testing and treatment of exposed individuals in high-risk populations. This study of a pilot Partner Services program in rural Uganda describes predictors of successful contact tracings and testing of partners of HIV+ individuals and possible barriers to contact. Partner contact tracing data was extracted from registers at seven Ministry of Health facilities between May and October 2016, to inform program implementation and scale up. A total of 464 HIV+ index clients named 660 sexual partners; 334/660 (51%) were contacted, 193/334 (58%) tested for HIV, and 61/193 (32%) tested HIV+. Current relationship status predicted contact [AOR = 0.23; (95% CI 0.15, 0.37), p < 0.0001] and testing [AOR = 0.19; (95% CI 0.09, 0.36), p < 0.0001]. Partner contact information type was associated with contact (p < 0.0001), and assisted disclosure with testing (p < 0.0001). Partner contact tracing is an effective means of identifying undiagnosed HIV infections.
