Tao G, et al. - Researchers conducted the study for analyzing the information on high-risk sexual behaviors (HRSB) related to gender of sex partner and associated sexually transmitted infection (STI)/HIV testing among Medicaid enrollees. They used the 2016 Centers for Medicare & Medicaid Services Medicaid claims data to identify enrollees aged 15 to 60 years with HRSB. Enrollees with HRSB were divided into two groups: those with same-sex partners and those with opposite-sex partners. In 2016, 1.2% of the 50 million Medicaid enrollees aged 15 to 60 were identified as HRSB enrollees. HRSB enrollees included 2.7% who had same-sex partners and 0.71% who had documented HIV infection. STI/HIV testing varied regionally among Medicaid enrollees with HRSB. Many enrollees were not tested for STI/HIV at the index visit where they were identified as HRSB.
