    BackgroundAn undiagnosed HIV infection remains a public health challenge. In the digital era, social media and digital health communication have been widely used to accelerate research, improve consumer health, and facilitate public health interventions including HIV prevention. ObjectiveWe aimed to evaluate and compare the projected cost and efficacy of different simulated Facebook (FB) advertisement (ad) approaches targeting at-risk populations for HIV based on new HIV diagnosis rates by age group and geographic region in the United States. MethodsWe used the FB ad platform to simulate (without actually launching) an automatically placed video ad for a 10-day duration targeting at-risk populations for HIV. We compared the estimated total ad audience, daily reach, daily clicks, and cost. We tested ads for the age group of 13 to 24 years (in which undiagnosed HIV is most prevalent), other age groups, US geographic regions and states, and different campaign budgets. We then estimated the ad cost per new HIV diagnosis based on HIV positivity rates and the average health care industry conversion rate. ResultsOn April 20, 2021, the potential reach of targeted ads to at-risk populations for HIV in the United States was approximately 16 million for all age groups and 3.3 million for age group 13 to 24 years, with the highest potential reach in California, Texas, Florida, and New York. When using different FB ad budgets, the daily reach and daily clicks per US dollar followed a cumulative distribution curve of an exponential function. Using multiple US 10ten−dayads,thecostpereverynewHIVdiagnosisrangedfromUS10 ten-day ads, the cost per every new HIV diagnosis ranged from US 13.09 to US 37.82,withanaveragecostofUS37.82, with an average cost of US 19.45. In contrast, a 1-time national ad had a cost of US 72.76toUS72.76 to US 452.25 per new HIV diagnosis (mean US 166.79).TheestimatedcostpernewHIVdiagnosisrangedfromUS166.79). The estimated cost per new HIV diagnosis ranged from US 13.96 to US 55.10forallagegroups(highestpotentialreachandlowestcostintheagegroups20−29and30−39years)andfromUS55.10 for all age groups (highest potential reach and lowest cost in the age groups 20-29 and 30-39 years) and from US 12.55 to US 24.67forallUSregions(withthehighestpotentialreachof6.2millionandthelowestcostpernewHIVdiagnosisatUS24.67 for all US regions (with the highest potential reach of 6.2 million and the lowest cost per new HIV diagnosis at US 12.55 in the US South). ConclusionsTargeted personalized FB ads are a potential means to encourage at-risk populations for HIV to be tested, especially those aged 20 to 39 years in the US South, where the disease burden and potential reach on FB are high and the ad cost per new HIV diagnosis is low. Considering the cost efficiency of ads, the combined cost of multiple low-cost ads may be more economical than a single high-cost ad, suggesting that local FB ads could be more cost-effective than a single large-budget national FB ad

    Rapid start of antiretroviral therapy (ART) has been associated with improvement in several HIV-related outcomes in clinical trials as well as demonstration projects, but how regional and contextual differences may affect the effectiveness of this intervention necessitates further study. In this study of a large, urban, Southern US clinic-based retrospective cohort, we identified 544 patients with a new diagnosis of HIV during 2016 to 2019 and compared HIV care continuum outcomes for the first 12 months of care before and after rapid start implementation. Kaplan-Meier time-to-event curves were used to summarize time to virologic suppression, and stepwise Cox, linear, and logistic regression models were used to create multivariate models to evaluate the association between rapid start and time to virologic suppression, medication adherence, and retention in care and sustained virologic suppression, respectively. We found that rapid start was significantly associated with improved medication adherence scores (+15.37 points, 95% confidence interval [CI] 9.36-21.39, P  < .01) and retention in care (adjusted odds ratio = 1.51, 95% CI 1.05-2.19, P  = .03). Time to virologic suppression (median 2.46 months before, 2.56 months after rapid start) and sustained virologic suppression were not associated with rapid start in our setting. Though rapid start was associated with improved medication adherence and retention in care, more support may be needed to achieve the same outcomes seen in other studies and sustained over the entire HIV care continuum, especially in settings with significant patient and systemic barriers to care such as unstable housing, lack of Medicaid expansion, and frequent coverage interruptions

    We aimed to identify psychosocial factors related to problem drinking among patients with poorly controlled human immunodeficiency virus (HIV) infection. We aimed to identify psychosocial factors related to problem drinking among those with poorly controlled HIV infection. Increased levels of interpersonal conflict were associated with greater severity of alcohol problems. Poorer mental health, medical mistrust and less satisfaction with one's physician related to excessive drinking. This secondary analysis used baseline data from a large multisite randomized controlled trial of substance users whose HIV infection was currently poorly controlled, from 11 urban hospitals across the USA. Participants were HIV-infected adult inpatients (n = 801; 67% male, 75% African American) with substance use histories. Participants self-reported on their drinking, perceived health, mental health, social relationships and patient-provider relationship. Structural equation models examined psychosocial factors associated with problem drinking, controlling for demographic covariates. Increased levels of interpersonal conflict were associated with greater severity of alcohol problems. Poorer mental health, medical mistrust and less satisfaction with one's physician were associated with excessive drinking. Several psychosocial factors, including interpersonal conflict, poor mental health (i.e. anxiety, depression and somatization), medical mistrust and less satisfaction with one's provider, were associated with problem drinking among HIV-infected substance users with poorly controlled HIV infection. The co-occurrence of these concerns highlights the need for comprehensive services (including attention to problem drinking, social services, mental health and quality medical care) in this at-risk group

    Preexposure prophylaxis (PrEP) is underused in persons who use drugs and justice-involved persons. In an ongoing randomized controlled trial in 4 US locations comparing patient navigation versus mobile health unit on time to initiation of HIV medication or PrEP for justice-involved persons who use stimulants or opioids and who are at risk for or living with HIV, we assessed HIV risk factors, perceived HIV risk, and interest in PrEP. Participants without HIV (n = 195) were 77% men, 65% White, 23% Black, and 26% Hispanic; 73% reported a recent history of condomless sex, mainly with partners of unknown HIV status. Of 34% (67/195) reporting injection drug use, 43% reported sharing equipment. Despite risk factors, many persons reported their risk for acquiring HIV as low (47%) or no (43%) risk, although 51/93 (55%) with PrEP indications reported interest in PrEP. Justice-involved persons who use drugs underestimated their HIV risk and might benefit from increased PrEP education efforts

    ObjectivesAnnual screening for gonorrhea [Neisseria gonorrhoeae (NG)] and chlamydia [Chlamydia trachomatis (CT)] is recommended for all sexually active persons living with HIV but is poorly implemented. Studies demonstrating no increases in NG and/or CT (NG/CT) case detection in clinics that successfully expanded NG/CT screening raise questions about this broad screening approach. We evaluated NG/CT case detection in the HIV Research Network during 2004-2014, a period of expanding testing.MethodsWe analyzed linear time trends in annual testing (patients tested divided by all patients in care), test positivity (patients positive divided by all tested), and case detection (the number of patients with a positive result divided by all patients in care) using multivariate repeated measures logistic regression. We determined trends overall and stratified by men who have sex with men (MSM), men who have sex exclusively with women, and women.ResultsAmong 15,614 patients (50% MSM, 26% men who have sex exclusively with women, and 24% women), annual NG/CT testing increased from 22% in 2004 to 60% in 2014 [adjusted odds ratio (AOR) per year 1.22 (1.21-1.22)]. Despite the increase in testing, test positivity also increased [AOR per year 1.10 (1.07-1.12)], and overall case detection increased from 0.8% in 2004 to 3.9% in 2014 [AOR per year 1.20 (1.17-1.22)]. Case detection was highest among MSM but increased over time among all 3 groups.ConclusionsNG/CT case detection increased as testing expanded in the population. This supports a broad approach to NG/CT screening among persons living with HIV to decrease transmission and complications of NG/CT and of HIV
