Getting to Zero: A Demonstration Project of Partner HIV Testing in the Prenatal Setting in Chicago, Illinois

Women who experience HIV seroconversion during pregnancy are missed during early routine pregnancy HIV screening and are at high risk of perinatal HIV transmission. Male partner HIV testing during routine prenatal care may be an effective primary prevention strategy by identifying women at risk of seroconversion and mitigating their risk. Our objective was to assess interest in and uptake of male partner HIV testing services offered during prenatal care. This demonstration project included all pregnant, English-speaking, HIV-negative women receiving publicly funded prenatal care in an urban hospital-based practice located in a high HIV prevalence area. Women were offered free HIV screening for their male sexual partners. From April 2017 to June 2018, enrolled women completed surveys on social demographics, medical access characteristics, and HIV testing history. Women were invited to bring their partners to a prenatal visit where HIV testing was offered to their male partners. Factors associated with women's interest in testing and completion of partner testing were assessed using bivariable and multivariable analyses. Of 392 women approached, 70% (N = 274) completed study surveys. Although the majority (76%, N = 200 of 264 respondents) of women desired their partner undergo HIV testing, testing was underutilized as only 18 (7%) male partners completed testing. While neither maternal characteristics nor male social or attitudinal factors were associated with interest in or completion of partner HIV testing, sensitivity analyses, performed with multiple imputation, demonstrated some association between interest and completion of partner testing and partner medical care access and utilization. In conclusion, although the majority of low-income women in an urban prenatal clinic expressed interest in having their partners undergo HIV testing, uptake of free partner HIV testing services was uncommon. A focused assessment of implementation and uptake barriers is needed to optimize partner testing and eliminate HIV transmission to mothers and their babies.
