1273. Reasons for Disengagement in Care among Individuals Receiving Pre-Exposure Prophylaxis (PrEP) from a Sexual Health Clinic

BACKGROUND: Pre-exposure prophylaxis (PrEP) effectively reduces HIV acquisition, but its efficacy depends on continued engagement through periods of high and low risk. Persistence in HIV prevention care has been low in real-world settings. In our program, 32% of patients are lost to care after their first visit and only 35% of patients are retained at their planned third visit. Reasons for low persistence in care are poorly described. METHODS: We identified all MSM who started PrEP between July 2015 and June 2018 at a sexual health clinic in an urban academic medical center in New York and had not had a visit in ≥6 months. We called patients between July 2018 and January 2019; those who were English speaking were given the option to complete an online questionnaire about current PrEP status, reasons for disengagement, and social and behavioral determinants of health (SBDH). RESULTS: Up to 710 patients were eligible for the study; over 700 calls were made. 125 participants agreed to participate and 57 (46%) completed the questionnaire. 24 patients (42%) were still actively taking PrEP. The most common reasons for starting PrEP were fear of getting HIV (58%), high self-perceived HIV risk (28%), and recommendations from friends (26%). Among those no longer taking PrEP, the most common reasons for discontinuation were cost/insurance issues (32%), lower perceived HIV risk (18%), concern about long-term side effects (12%), and trouble attending every-3-month appointments (12%). For those stopping due to lower perceived risk, 40% were in a monogamous relationship, 60% were less sexually active, and 20% always used a condom or did not engage in receptive anal intercourse. 56% of patients had at least 1 major life event in the preceding 3 months, including loss of a job (25%), breakup with a partner (12%), illness or death of a family member (11%), or unstable housing (8%). 47% used drugs or alcohol before sex in the past month including 39% not on PrEP. CONCLUSION: Reasons for engagement, disengagement, and re-engagement are highly variable at the individual level. Cost and insurance issues were common in spite if clinic resources available to cover the cost of visits and medications. Life trauma was common. Individualized interventions to address SBDH may be required to engage and retain individuals in HIV prevention care. DISCLOSURES: All authors: No reported disclosures.
