HIV testing in a high prevalence urban area in the US: Identifying missed opportunities two ways.

International Journal of Epidemiology

Routine opt-out HIV testing in healthcare settings is often not implemented to its fullest extent. We assessed factors contributing to missed HIV testing opportunities at an academic medical center in Chicago, Illinois, with a routine HIV screening program.

Retrospective analysis of HIV testing in clinical encounters was performed using multivariate regession models. Missed opportunities were defined as 1) an encounter during which an HIV test was not conducted on a patient later diagnosed with HIV, or 2) an encounter in which a bacterial STI test was performed without HIV testing.

Of 122 people newly diagnosed with HIV from 2011-2018, 98 patients had 1215 prior encounters, of which 82.8% were missed opportunities. Female gender, persons not known to be men who have sex with men, and encounter location other than inpatient had higher odds of a missed opportunity. Nearly half (48.4%) of 104,678 bacterial STI testing encounters were missed opportunities. Female gender, older age, lack of syphilis testing, and location outside the emergency department had higher odds of a missed opportunity.

We found a high number of missed HIV testing opportunities, which could be reduced by strengthening routine screening and increasing targeted testing concurrent with STI screening.

Psychological distress and adherence to anti-retroviral therapy or pre-exposure prophylaxis regimens among Urban Black gay and bisexual men (MSM).

International Journal of Epidemiology

Urban Black gay, and bisexual men (MSM) bear a disproportionate burden of HIV in the U.S. Mental health is a barrier to adherence to both antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP). The objective was to determine the association between psychological distress and ART or PrEP adherence among urban Black MSM.

Using data from a four-year prospective cohort study, adherence to ART was defined as > 95% and PrEP was defined as > 80% of doses taken in the past 30 days. Psychological distress measures included difficulty sleeping; feeling anxious; suicidality; feeling sad or depressed; feeling sick, ill, or not well in the past 3 months; high (vs. low) overall psychological distress was classified as above the median value. Associations were examined using Chi-square, Fisher's exact tests, and logistic regression.

Among 165 Black MSM, 44.2% (73) reported high psychological distress. 65.3% (47/72) of participants living with HIV and 39.8% (37/93) of HIV negative participants were ART or PrEP adherent, respectively. Education was significantly associated with PrEP adherence (p = 0.038). Non-injection drug use in the past 3 months (p = 0.008), difficulty sleeping (p = 0.010), feeling anxious (p = 0.003), and feeling sad or depressed (p < 0.001), and overall psychological distress (p < 0.001) were significantly associated with ART adherence. High psychological distress was significantly associated with a reduced odds of ART adherence (aOR 0.23; 95% CI = 0.08-0.70) adjusting for age and non-injection drug use.

Increased psychological distress was significantly associated with ART nonadherence and may represent an important barrier to viral suppression.

Characteristics of HIV/sexually transmitted infections among men who have sex with men and women in Bangkok, Thailand.

International Journal of Epidemiology

Men who have sex with men (MSM) are a key HIV target population in Thailand. An important subgroup is men who have sex with men and women (MSMW) as they can sexually transmit infections between individuals with different gender identities. This study compared the sexually transmitted infection risk behavior of different types of men in Thailand.

We retrospectively reviewed the medical records of 839 consecutive male patients who visited an STI clinic in Bangkok, Thailand, between 2014 and 2020.

Men who have sex with women only (MSWO) predominated (58.0%), followed by men who have sex with men only (MSMO, 32.2%) and MSMW (9.8%). MSMW and MSMO shared similar sexual risk behaviors, such as significantly higher median numbers of sex partners (10 and 8, respectively) than MSWO (5; Kruskal-Wallis, p < 0.001). MSMW had the highest prevalence of concurrent sexual partnerships (91.4%), significantly different from MSWO (61.2%) and MSMO (76.7%; chi-squared, p < 0.001). HIV and syphilis prevalence was significantly higher for MSMO (48.9% and 51.1%) and MSMW (42.7% and 48.8%) than MSWO (12.3% and 20.9%; chi-squared, p < 0.001).

MSMW exhibited similar sexual risk behavior and high HIV/STI prevalence comparable to MSMO.

Impact of community health worker intervention on PrEP knowledge and use in Rakai, Uganda: A mixed methods, implementation science evaluation.

International Journal of Epidemiology

Effective models of support for HIV pre-exposure prophylaxis (PrEP) are needed for populations at elevated risk. In a hyperendemic Ugandan fishing community, PrEP counseling was provided through a situated Information, Motivation, and Behavioral Skills (sIMB)-based community health worker (CHW) intervention. We evaluated the intervention using a mixed-methods, implementation science design.

We surveyed all community members aged 15-49 through the Rakai Community Cohort Study. We used multivariable logistic regressions with generalized estimating equations to estimate the intervention's effect on PrEP knowledge and utilization. To understand intervention experiences and mechanisms, we conducted 74 qualitative interviews with 5 informant types (clients, CHWs, program staff, community leaders, health clinic staff) and analyzed data using an iterative, deductive approach. A mobile phone application provided intervention process implementation data.

Individuals self-reporting receipt of the CHW intervention showed significantly higher PrEP knowledge (N = 1848, PRR: 1.10, 95% CI: 1.06-1.14, p = <.0001), PrEP ever use (N = 1176, PRR: 1.77, 95% CI: 1.33-2.36, p = <.0001), and PrEP current use (N = 1176, PRR: 1.86, 95% CI: 1.22-2.82, p = 0.0039) compared to those who did not. Qualitative findings attributed positive PrEP outcomes to CHW counseling and effective use of motivational interviewing skills by CHWs. Salient themes across the RE-AIM framework included support for the CHW intervention and PrEP across clients, community, and implementers. Mobile application data demonstrated consistent delivery of the PrEP module throughout implementation.

CHWs improved PrEP knowledge and use among clients in an HIV hyperendemic fishing community. Mixed-methods, implementation science evaluations can inform adaptation of similar PrEP implementation strategies.
