Abstract

BACKGROUND: Clinical decision support (CDS) is a promising intervention for improving uptake of HIV testing and pre-exposure prophylaxis (PrEP). However, little is known regarding provider perspectives on acceptability, appropriateness, and feasibility of CDS for HIV prevention in pediatric primary care, a key implementation setting.

METHODS: This was a cross-sectional multiple methods study utilizing surveys and in-depth interviews with pediatricians to assess acceptability, appropriateness, and feasibility of CDS for HIV prevention, as well as to identify contextual barriers and facilitators to CDS. Qualitative analysis utilized work domain analysis and a deductive coding approach grounded in the Consolidated Framework of Implementation Research. Quantitative and qualitative data were merged to develop an Implementation Research Logic Model to conceptualize implementation determinants, strategies, mechanisms, and outcomes of potential CDS use.

RESULTS: Participants (n = 26) were primarily white (92%), female (88%), and physicians (73%). Using CDS to improve HIV testing and PrEP delivery was perceived as highly acceptable (median score 5), IQR [4-5]), appropriate (5, IQR [4-5]), and feasible (4, IQR [3.75-4.75]) using a 5-point Likert scale. Providers identified confidentiality and time constraints as two key barriers to HIV prevention care spanning every workflow step. With respect to desired CDS features, providers sought interventions that were integrated into the primary care workflow, standardized to promote universal testing yet adaptable to the level of a patient's HIV risk, and addressed providers' knowledge gaps and bolstered self-efficacy in providing HIV prevention services.

CONCLUSIONS: This multiple methods study indicates that clinical decision support in the pediatric primary care setting may be an acceptable, feasible, and appropriate intervention for improving the reach and equitable delivery of HIV screening and PrEP services. Design considerations for CDS in this setting should include deploying CDS interventions early in the visit workflow and prioritizing standardized but flexible designs.

Abstract

<p><strong>INTRODUCTION: </strong>Youth account for a disproportionate number of new HIV infections; however, pre-exposure prophylaxis (PrEP) use is limited. We evaluated PrEP counselling rates among non-Hispanic Black youth in the United States after a bacterial sexually transmitted infection (STI) diagnosis.</p>

<p><strong>METHODS: </strong>We conducted a retrospective cohort study of Black youth receiving care at two academically affiliated clinics in Philadelphia between June 2014 and June 2019. We compared PrEP counselling for youth who received primary care services versus those who did not receive primary care services, all of whom met PrEP eligibility criteria due to STI diagnosis per U.S. Centers for Disease Control and Prevention clinical practice guidelines. Two logistic regression models for receipt of PrEP counselling were fit: Model 1 focused on sexual and gender minority (SGM) status and Model 2 on rectal STIs with both models adjusted for patient- and healthcare-level factors.</p>

<p><strong>RESULTS: </strong>Four hundred and sixteen patients met PrEP eligibility criteria due to STI based on sex assigned at birth and sexual partners. Thirty patients (7%) had documentation of PrEP counselling. Receipt of primary care services was not significantly associated with receipt of PrEP counselling in either Model 1 (adjusted OR (aOR) 0.10 [95% CI 0.01, 0.99]) or Model 2 (aOR 0.52 [95% CI 0.10, 2.77]). Receipt of PrEP counselling was significantly associated with later calendar years of STI diagnosis (aOR 6.80 [95% CI 1.64, 29.3]), assigned male sex at birth (aOR 26.2 [95% CI 3.46, 198]) and SGM identity (aOR 317 [95% CI 39.9, 2521]) in Model 1 and later calendar years of diagnosis (aOR 3.46 [95% CI 1.25, 9.58]), assigned male sex at birth (aOR 18.6 [95% CI 3.88, 89.3]) and rectal STI diagnosis (aOR 28.0 [95% CI 8.07, 97.5]) in Model 2. Fourteen patients (3%) started PrEP during the observation period; 12/14 (86%) were SGM primary care patients assigned male sex at birth.</p>

<p><strong>CONCLUSIONS: </strong>PrEP counselling and uptake among U.S. non-Hispanic Black youth remain disproportionately low despite recent STI diagnosis. These findings support the need for robust investment in PrEP-inclusive sexual health services that are widely implemented and culturally tailored to Black youth, particularly cisgender heterosexual females.</p>

Abstract

<p>Adolescents with suboptimal medication taking may deceive caregivers about non-adherence. We conducted a 5-year longitudinal study of adolescents monitored simultaneously with both easily manipulated (e.g., self-report) and hard to manipulate (e.g., microelectronic data) strategies. Adolescents with repeatedly high adherence on the former and low adherence on the latter were invited along with their parental figures ("parents") to participate. We conducted focus groups and semi-structured interviews, separately for adolescents and parents, to elucidate drivers of discordant measures. Forty-seven adolescents and 26 parents participated in focus groups and 4 adolescents were interviewed. Adolescents described hiding pills, discarding pills, and lying. Their motivations included fear of disappointing those who care about them, desire to avoid admonishment by parents and clinic staff, and desire to avoid remedial adherence counseling. Both adolescents and parents considered negative feedback for prior poor adherence to be key motivation to hide current poor adherence from clinic staff. Providing positive feedback for truth-telling, rather than for "evidence" of excellent adherence, might help adolescent patients and their parents to develop stronger treatment alliances with each other and with clinic staff. Such alliances would allow adherence interventions to be better targeted and more fruitful in increasing adherence.</p>

Abstract

<p>Despite access to nationally supplied antiretroviral treatment, viral load suppression rates remain suboptimal in the Dominican Republic. Counseling and support services are available but mainly targeted to those identified as having the most need. At Clínica de Familia La Romana (CFLR) in La Romana, all patients undergo a structured baseline interview including exploration of expected barriers to care. We conducted a retrospective cohort study of a random sample of patients at CFLR with treatment initiation between 1 January 2015 and 1 December 2017 to determine if self-identified barriers to HIV care predict viral load suppression. Viral load suppression occurred in 63% of the 203 patients evaluated. Lack of food ( = 19) was significantly associated with lack of viral suppression (OR 3.0, 95% CI 1.14-7.87). Nondisclosure of HIV status ( = 24) showed evidence for a protective effect (OR 0.33; 95% CI 0.11-1.0). Further steps should be taken to address food insecurity as well as to understand associated barriers to care among individuals with food insecurity.</p>

Abstract

<p>The effects of mental health comorbidities and social support on the HIV pre-exposure prophylaxis (PrEP) care continuum are unknown. We conducted a cross-sectional study of men and transgender individuals, ≥ 18&nbsp;years-old, with ≥ 2 male or transgender partners, or recent condomless anal intercourse. Surveys assessed demographics, mental health treatment, depressive symptomatology, social support, and PrEP-related social contacts. Logistic regression assessed associations between these factors and PrEP uptake and persistence. Participants (n = 247) were 89% cis-male and 46% African-American. Median age was 27 (IQR:23-33). Thirty-seven percent had ever used PrEP, of whom 18% discontinued use. High depressive symptomology was identified in 11% and 9% were receiving mental health treatment. There were no significant associations between depressive symptoms or mental health treatment on the odds of PrEP uptake or discontinuation. Each additional PrEP contact conferred a greater odds of uptake (aOR:1.24, 95% CI: 1.09-1.42). Network-level targets may produce fruitful interventions to increase PrEP uptake.</p>

Abstract

<p>Psychological reactance is an aversive response to perceived threats against personal agency. For adolescents receiving HIV treatment in Botswana, we utilized a two-question, medication-specific reactance tool to assess whether: (1) verbal reminders to take medicines made adolescents want to avoid taking them, and, (2) whether adolescents felt anger when reminded to take medicines. Reactant adolescents had 2.05-fold (95% CI 1.23, 3.41) greater odds of treatment failure than non-reactant adolescents (p = 0.03). Adjusted risk of treatment failure was 14% (95% CI 3%, 28%) greater for each point elevation in reactance score (p = 0.016). Autonomy over medication-taking did not modify the association between reactance and treatment failure. Psychological reactance may be a useful interventional target for improving adolescent adherence.</p>

Abstract

<p><strong>PURPOSE: </strong>This study aimed to determine if disclosure of HIV status to adolescents impacted their medication adherence and how medication autonomy might explain observed effects.</p>

<p><strong>METHODS: </strong>Three hundred adolescents on HIV treatment using electronic medication monitors were followed for 24&nbsp;months while undergoing routine care. One hundred six of the adolescents were HIV disclosure-naïve and HIV status disclosure in this group was assessed quarterly. Analyses included data from the 75 adolescents who experienced disclosure during the study providing adherence and autonomy data both predisclosure and postdisclosure. Segmented generalized estimating equations were used to examine the trend of adherence and autonomy predisclosure and postdisclosure. Covariates assessed include age at disclosure, sex, and orphan status.</p>

<p><strong>RESULTS: </strong>Median age at study entry was 12.2&nbsp;years (interquartile range 11.6-12.9). Incident disclosure occurred in 75 (71%) of the adolescents at a median age of 13.1&nbsp;years (interquartile range 12.5-13.9). Adherence decreased by 11% (95% confidence interval [CI] 7-15, p &lt; .001) during the predisclosure period and by 22% (95% CI 9-36, p&nbsp;= .001) during the postdisclosure period. Adolescents' autonomy over their medication-taking increased over time, but disclosure did not impact the rate of increase in measured medication-taking autonomy. On a scale of 1-4 assessing autonomy (1&nbsp;= receiving directly observed therapy and 4&nbsp;= taking medicines mostly without supervision), autonomy increased by an average of .03 units/month (95% CI .02-.03, p &lt; .001) predisclosure and by .05 units/month (95% CI&nbsp;-.01 to .11, p&nbsp;= .42) postdisclosure.</p>

<p><strong>CONCLUSIONS: </strong>The findings suggest that, among perinatally HIV infected adolescents, HIV status disclosure may adversely impact treatment adherence. Postdisclosure support to HIV infected adolescents should be intensified.</p>

Abstract

<p><strong>PURPOSE: </strong>The aim of the study was to characterize perceived social support for young men and transgender women who have sex with men (YM/TWSM) taking HIV pre-exposure prophylaxis (PrEP).</p>

<p><strong>METHODS: </strong>Mixed-methods study of HIV-negative YM/TWSM of color prescribed oral PrEP. Participants completed egocentric network inventories characterizing their social support networks and identifying PrEP adherence support figures. A subset (n&nbsp;= 31) completed semistructured interviews exploring adherence support and qualities of PrEP support figures. We calculated proportions of role types (e.g., family), individuals disclosed to regarding PrEP use, and PrEP-supportive individuals within each participant network. Interviews were analyzed using an inductive approach.</p>

<p><strong>RESULTS: </strong>Participants (n&nbsp;= 50) were predominately African American men who have sex with men. Median age was 22&nbsp;years (interquartile range: 20-23). Biologic family were the most common support figures, reported by 75% of participants (mean family proportion .37 [standard deviation (SD): .31]), followed by 67% reporting friends (mean friend proportion .38 [SD: .36]). Most network members were aware (mean disclosed proportion .74 [SD: .31]) and supportive (mean supportive proportion .87 [SD: .28]) of the participants' PrEP use. Nearly all (98%) participants identified ≥1 figure who provided adherence support; more often friends (48%) than family (36%). Participants characterized support as instrumental (e.g., transportation); emotional (e.g., affection); and social interaction (e.g., taking medication together). Key characteristics of PrEP support figures included closeness, dependability, and homophily (alikeness) with respect to sexual orientation.</p>

<p><strong>CONCLUSIONS: </strong>Although most YM/TWSM identified family in their support networks, friends were most often cited as PrEP adherence support figures. Interventions to increase PrEP adherence should consider integrated social network and family-based approaches.</p>

Abstract

<p>We aimed to discover barriers and facilitators of HIV pre-exposure prophylaxis (PrEP) adherence in young men and transgender women of color who have sex with men (YMSM/TW). Short-term and sustained adherence were measured by urine tenofovir concentration and pharmacy refills, respectively. Optimal adherence was defined as having both urine tenofovir concentration consistent with dose ingestion within 48&nbsp;h and pharmacy refills consistent with ≥ 4 doses per week use. Participants completed semi-structured interviews exploring adherence barriers and facilitators. Participants (n = 31) were primarily African-American (68%), mean age 22&nbsp;years (SD: 1.8), and 48% had optimal adherence. Adherence barriers included stigma, health systems inaccessibility, side effects, competing stressors, and low HIV risk perception. Facilitators included social support, health system accessibility,&nbsp;reminders/routines, high HIV risk perception, and personal agency. Our findings identify targets for intervention to improve PrEP adherence in these populations, including augmenting health activation and improving accuracy of HIV risk perception.</p>

Abstract

<p>In adults living with HIV, pharmacy refill data are good predictors of virologic failure (VF). The utility of pharmacy refill data for predicting VF in adolescents has not been reported. We evaluated data from 291 adolescents on antiretroviral therapy. The main outcome measure was VF, defined as two consecutive HIV viral load measurements ≥ 400 copies/mL during 24-months of follow-up. Pharmacy refill non-adherence was defined as two consecutive refill adherence measurements &lt; 95% during the same period. Fifty-three (18%) adolescents experienced VF. One hundred twenty-eight (44%) adolescents had refill non-adherence. Refill non-adherence had poor discriminative ability for indicating VF (receiver operating characteristic AUC = 0.60). Sensitivity and specificity for predicting VF was poor (60% (95% CI 46-74%) and 60% (95% CI 53-66%), respectively). The lack of a viable surrogate for VF in adolescents highlights the urgent need for more access to virologic testing and novel methods of monitoring adolescent treatment adherence.</p>
