Barriers and facilitators to uptake and persistence on prep among key populations in Southern Province, Zambia: a thematic analysis.

BACKGROUND: Especially in high HIV prevalence contexts, such as Zambia, effective biomedical prevention tools are needed for priority populations (PPs), including key populations (KPs), who are at higher risk. HIV pre-exposure prophylaxis (PrEP) has been scaled up nationally in Zambia, but little is known about barriers to PrEP use among specific PPs to date. METHODS: To understand barriers and facilitators to PrEP use in Zambia, we conducted a qualitative case study of PrEP services to PPs including sero-discordant couples (SDCs), female sex workers (FSWs), and men who have sex with men (MSM) in Livingstone. The study conducted in 2021 included in-depth interviews (n = 43) guided by the socio-ecological model, and focus group discussions (n = 4) with clinic and community-based providers and PrEP-eligible clients including users and non-users across PP groups. We used thematic analysis to analyze data using codes derived both deductively and inductively. RESULTS: We found multilevel barriers and facilitators to PrEP use. Cross-cutting barriers shared across PP groups included amplifying effects of PrEP being mistaken for antiretroviral drugs used to treat HIV, including anticipated stigma, and concerns about side-effects based on both misinformation and experience. In addition, stigmatized identities, particularly that of MSM, served as a barrier to PrEP use. The fear of being mislabeled as having HIV was of greatest concern for FSWs. Facilitators to PrEP use primarily included the importance of confidential, KP-sensitive services, and the role of informed, supportive family, friends, and peers. Participants across all PP groups urged expanded education efforts to increase awareness of PrEP within the general population toward mitigating concerns of being mislabeled as living with HIV. CONCLUSION: To our knowledge, this is the first qualitative study of the PrEP cascade among multiple PPs in Zambia. This study provides important explanation for the low rates of PrEP continuation found in earlier demonstration trials among KPs in Zambia. The study also offers recommendations for programming efforts going forward such as inclusive PrEP awareness campaigns, expanded KP sensitivity training, and related efforts to thwart PrEP stigma while expanding access.

Fostering Access to PrEP Among Adolescent Girls and Young Women Aged 16 to 24 Years at High Risk of HIV Through the DREAMS Initiative in Four Districts in Zambia.

Adolescent girls and young women (AGYW) in sub-Saharan Africa remain at high risk for HIV, yet limited data exist on implementation of HIV pre-exposure prophylaxis (PrEP) for this group. We examined PrEP uptake among AGYW using a retrospective cohort enrolled in the Determined Resilient Empowered AIDS-free Mentored Safe (DREAMS) initiative in Zambia between October 2020 and March 2022. Consent was obtained from eligible AGYW at substantial risk for HIV, and they voluntarily participated in PrEP. Multivariable logistic regression was used to examine factors associated with PrEP refills following initiation. Of 4,162 HIV-negative AGYW, 3,233 (77%) were at substantial risk and initiated on PrEP. Overall, 68% of AGYW had at least one refill, but this differed significantly by age group and district. DREAMS was successful at reaching AGYW with PrEP services. More evidence is needed to assess reasons for discontinuation and to improve persistence for those with sustained HIV risk.

Primary care clinical provider knowledge and experiences in the diagnosis and treatment of tick-borne illness: a qualitative assessment from a Lyme disease endemic community.

BACKGROUND: Primary care and frontline healthcare providers are often the first point of contact for patients experiencing tick-borne disease (TBD) but face challenges when recognizing and diagnosing these diseases. The specific aim of this study was to gain a qualitative understanding of frontline and primary care providers' knowledge and practices for identifying TBDs in patients. METHODS: From fall 2018 to spring 2019, three focus groups were conducted with primary care providers practicing in a small-town community endemic to Lyme disease (LD) and with emerging incidence of additional TBDs. A follow up online survey was distributed to urgent and emergency care providers in the small-town community and an academic medical center within the referral network of the local clinical community in spring and summer 2019. Qualitative analysis of focus group data was performed following a grounded theory approach and survey responses were analyzed through the calculation of descriptive statistics. RESULTS: Fourteen clinicians from three primary care practices participated in focus groups, and 24 urgent and emergency care clinicians completed the survey questionnaire. Four overarching themes emerged from focus group data which were corroborated by survey data. Themes highlighted a moderate level of awareness on diagnosis and treatment of LD among participants and limited knowledge of diagnosis and treatment for two other regionally relevant TBDs, anaplasmosis and babesiosis. Providers described challenges and frustrations in counseling patients with strong preconceptions of LD diagnosis and treatment in the context of chronic infection. Providers desired additional point-of-care resources to facilitate patient education and correct misinformation on the diagnosis and treatment of TBDs. CONCLUSIONS: Through this small study, it appears that clinicians in the small-town and academic medical center settings are experiencing uncertainties related to TBD recognition, diagnosis, and patient communication. These findings can inform the development of point-of-care resources to aid in patient-provider communication regarding TBDs and inform the development of continuing medical education programs for frontline and primary care providers.
