Texting Lost-to-follow-up PrEP Patients from a San Francisco Sexual Health Clinic.

It is critical to understand what happens when PrEP patients are lost-to-follow-up (LTFU) and, where appropriate, attempt to re-engage them in care with the goal of preventing future human immunodeficiency virus (HIV) acquisition. We evaluated the benefits and limitations of using text-based outreach to re-engage with LTFU PrEP patients and offer re-initiation of PrEP care. Using text-messaging, we surveyed San Francisco City Clinic patients who started PrEP from January 2015 to October 2019 and were LTFU by October 1, 2020. Our goals were to better understand (1) whether our patients remained on PrEP through another provider or source, (2) why patients choose to discontinue PrEP, and (3) whether text-based outreach could successfully re-engage such patients in care. Multiple-choice survey questions were analyzed quantitatively to determine the proportion of respondents selecting each option; free-text responses were analyzed qualitatively using an inductive approach to identify any additional recurring themes. Of 846 eligible survey recipients, 130 responded (overall response rate 15.4%). Forty-two respondents (32.3%) were still on PrEP through another provider while 88 (67.7%) were not. Common reasons for stopping PrEP included: COVID-19-related changes in sex life (32.3% of responses), concerns regarding side effects (17.7%), and the need to take a daily pill (8.3%). Free text responses revealed additional concerns regarding risk compensation. While 32 participants agreed to be contacted by City clinic staff for PrEP counseling, only 6 were reached by phone and none of the six subsequently restarted PrEP. We learned that text messaging is a possible approach to survey certain PrEP program participants to determine who is truly LTFU and off PrEP, and to better understand reasons for PrEP discontinuation. While such information could prove valuable as programs seek to address barriers to PrEP retention, efforts to improve acceptability and increase response rates would be necessary. We were less successful in re-engaging LTFU patients in PrEP care, suggesting that text-messaging may not be the optimal strategy for this purpose.

Implementation of pre-exposure prophylaxis at a community pharmacy through a collaborative practice agreement with San Francisco Department of Public Health.

OBJECTIVE: To discuss the design and implementation of a community pharmacy-initiated HIV pre-exposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) program developed in collaboration with the San Francisco Department of Public Health (SFDPH). SETTING: A community pharmacy in San Francisco and the SFDPH developed a collaborative practice agreement (CPA) that allowed community pharmacists to initiate PrEP and PEP to prevent HIV acquisition and increase uptake in vulnerable populations. PRACTICE DESCRIPTION: A community pharmacy in San Francisco's Mission District, an urban, historically Hispanic/Latino/Latinx neighborhood. The primary collaborative practice team consisted of 1 community pharmacy technician, 4 community pharmacists, and 1 designated overseeing physician at SFDPH. PRACTICE INNOVATION: The pharmacy and the SFDPH collaborated together for 20 months from start to implementation of the CPA and the PrEP program. An interdisciplinary team of pharmacists, pharmacy personnel, public health physicians, and health department staff members worked together to design, launch, and maintain the program. Pharmacists were trained by SFDPH staff members on HIV testing and counseling and implementation of the PrEP protocol, including PEP initiation and sexually transmitted disease testing. A Department of Public Health secure portal was used to share patient information. An SFDPH physician reviewed patients' charts regularly and communicated with PrEP pharmacists as needed. RESULTS: Between April 2018 and the end of March 2019, 6 patients received PEP and 53 patients completed a PrEP initiation visit, of whom 96% (n = 51) filled their prescription. Approximately 47% (n = 24) of clients who started PrEP self-identified as Hispanic or Latino, 10% (n = 5) were black or African American, and 82% (n = 42) identified as men who have sex with men. CONCLUSION: Implementation of a CPA between a community pharmacy and a local health department enabled the launch of pharmacist-delivered PrEP, further expanding the landscape of access points to vulnerable populations in San Francisco.
