Background: Growing evidence has shown feasibility for human immunodeficiency virus (HIV) prevention service integration in pharmacies, including HIV testing and screening for pre-exposure prophylaxis (PrEP). Yet, further work is needed to determine whether pharmacies can effectively reach those at increased risk of HIV transmission.

Objective: We aimed to describe the HIV risk profiles and willingness to obtain HIV prevention services from a sample of pharmacy clients.

Background: Racial inequities in HIV in the United States (US) are pervasive. Pre-exposure prophylaxis (PrEP) is one of the most effective yet underutilized HIV prevention strategies, and stark inequities in PrEP uptake exist. Lack of access to PrEP clinics is a major barrier to access that could be overcome by integrating pharmacists into the provision of PrEP services including prescribing and dispensing.

Importance: Daily preexposure prophylaxis (PrEP) use can prevent up to 99% of HIV infections; however, PrEP uptake is low due to poor access to PrEP-prescribing locations for populations at increased risk for HIV, especially in the southeastern US. Pharmacies are a feasible option to increase PrEP access, but little is known about how they could complement current PrEP-prescribing locations.

Objective: To examine geographic distributions of current PrEP-prescribing locations compared with pharmacies and the facility to need ratios (PFNRs) according to HIV risk in the Southeast and describe the potential reach of pharmacies to expand PrEP access.

Background: Primary care providers are regarded as trustworthy sources of information about COVID-19 vaccines. Although primary care practices often provide information about common medical and public health topics on their practice websites, little is known about whether they also provide information about COVID-19 vaccines on their practice websites.

Objective: This study aimed to investigate the prevalence and correlates of COVID-19 vaccine information on family medicine practices' website home pages in the United States.

Background: Mean active degree is an important proxy measure of cross-sectional network connectivity commonly used in HIV/sexually transmitted infection epidemiology research. No current studies have compared measurement methods of mean degree using a cross-sectional study design for men who have sex with men (MSM) in the United States. We compared mean degree estimates based on reported ongoing main and casual sexual partnerships (current method) against dates of first and last sex (retrospective method).

Background: The global COVID-19 pandemic has the potential to indirectly impact transmission dynamics and prevention of HIV and other sexually transmitted infections (STI). It is unknown what combined impact reductions in sexual activity and interruptions in HIV/STI services will have on HIV/STI epidemic trajectories.

Methods: We adapted a model of HIV, gonorrhea, and chlamydia for a population of approximately 103 000 men who have sex with men (MSM) in the Atlanta area.

Background: The global COVID-19 pandemic has the potential to indirectly impact the transmission dynamics and prevention of HIV and other sexually transmitted infections (STI). Studies have already documented reductions in sexual activity ("sexual distancing") and interruptions in HIV/STI services, but it is unknown what combined impact these two forces will have on HIV/STI epidemic trajectories.

Methods: We adapted a network-based model of co-circulating HIV, gonorrhea, and chlamydia for a population of approximately 103,000 men who have sex with men (MSM) in the Atlanta area.

Background: The US Centers for Disease Control and Prevention (CDC) recommends comprehensive sexually transmitted infection (STI) screening every 3-6 months for men who have sex with men (MSM) using human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP). The gaps between these recommendations and clinical practice by region have not been quantified.

Methods: We used survey data collected from the internet-based ARTnet study between 2017 and 2019 on STI screening among MSM across the United States, stratified by current, prior, and never PrEP use.

Background: UNAIDS estimates global HIV investment needs in low- and middle-income countries (LMICs) at $26 billion per year in 2020. Yet international financing for HIV programs has stagnated amidst despite the increasing number of people requiring and accessing treatment. Despite increased efficiencies in HIV service delivery, evaluating programs for greater efficiencies remains necessary.
