A Randomized Controlled Trial of Personalized Text Message Reminders to Promote Medication Adherence Among HIV-Positive Adolescents and Young Adults

Developing and testing a web-based platform for antiretroviral therapy (ART) adherence support among adolescents and young adults (AYA) living with HIV

Objective

Describe the development and testing of a web-based platform for antiretroviral treatment (ART) adherence support among HIV+ adolescents and young adults (AYA) in a randomized controlled trial (RCT).

Methods

A seven-member multi-disciplinary team operationalized the flat, password protected, web-based platform. Manualized protocols guided the objectives and content for each of the eight web-based sessions. Team members evaluated usability and content validity. Client satisfaction and perceived ease of use was evaluated with the first ten HIV+ AYA participants.

Results

The web-based platform was developed, evaluated, refined, implemented and pilot tested between September 2020 to April 2022. Usability was rated as high; the evaluation of content validity showed an excellent fit between session content and objectives. HIV+ AYA participants (mean age = 24.2 years) were satisfied with the quality, type, and amount of support/education received, and found the platform easy to use, operate, and navigate. Average time spent per session was 6.5 min.

Conclusion

Findings support the usability, validity, acceptability, and feasibility of this web-based platform for ART adherence support among HIV+ AYA.

Innovation

Our research and findings are responsive to research gaps and the need for transparency in the methodological development and testing of web-based control arms for ART adherence support among HIV+ AYA.

Acceptability of an automated directly observed therapy (DOT) application for PrEP adherence support among young men who have sex with men: a qualitative exploration

Pre-exposure prophylaxis (PrEP) adherence remains a challenge among young men who have sex with men (MSM). We developed and tested a smartphone application ("app"), "DOT Diary", which combines automated directly observed therapy (DOT) with information about PrEP protection levels, pill-taking reminders, a sexual behavior diary, and a PrEP dosing calendar. To contextualize trial results, we qualitatively explored participants' app experiences. The trial enrolled 100 young MSM in San Francisco and Atlanta. Participants were randomized 2:1 to DOT Diary versus standard-of-care and followed for 24 weeks. Interviews were conducted with 24 intervention participants. Data were analyzed using a memo-writing approach. Most expressed overall satisfaction with the app ("it was good for its purpose"), despite concerns about technical glitches. The most popular app features were the monthly calendar showing days PrEP was taken and information about level of protection based on pills taken. The DOT component helped participants establish PrEP routines. The reminders were "annoying but effective" at motivating dosing. Opinions about the sexual behavior diary varied. Overall, DOT Diary was acceptable; participants were willing to use it daily to record pill-taking. Critical components included the information about PrEP protection levels and calendar, while others may be modified to improve future success.Trial registration: ClinicalTrials.gov identifier: NCT03771638.

A Web-Based Antiretroviral Therapy Adherence Intervention (Thrive With Me) in a Community-Recruited Sample of Sexual Minority Men Living With HIV: Results of a Randomized Controlled Study

BACKGROUND

Most new HIV infections are attributed to male-to-male sexual contact in the United States. However, only two-thirds of sexual minority men living with HIV achieve an undetectable viral load (UVL). We tested a web-based antiretroviral therapy adherence intervention called Thrive with Me (TWM) with core features that included medication self-monitoring and feedback, HIV and antiretroviral therapy information, and a peer-to-peer exchange.

OBJECTIVE

We assessed the efficacy of TWM on HIV UVL among adult (aged ≥18 years) sexual minority men. Moreover, we assessed the impact of overall engagement and engagement with specific intervention features on HIV UVL.

METHODS

In total, 401 sexual minority men (mean age 39.1, SD 10.8 y; 230/384, 59.9% African American) in New York City were recruited between October 2016 and December 2019 and randomized to receive TWM (intervention) or a weekly email newsletter (control) for 5 months. Computerized assessments occurred at baseline and months 5, 11, and 17. The primary outcome was a dichotomous measure of HIV UVL (≤20 copies/μL). Generalized estimating equations with robust SEs were used to assess the effect of the TWM intervention on HIV UVL over the follow-up period in an unadjusted model and a model adjusted for baseline differences and then stratified by baseline recent drug use urinalysis. In secondary analyses, generalized linear models were used to estimate risk differences in the association of overall engagement with TWM (the sum of the number of days participants accessed ≥1 screen of the TWM intervention out of a possible 150 days) and engagement with specific TWM components on HIV UVL throughout the 17-month intervention period.

RESULTS

Participant retention was 88.5% (355/401; month 5), 81.8% (328/401; month 11), and 80.3% (322/401; month 17). No consistent differences in HIV UVL were found between those randomized to receive TWM or the control at the 5- (difference-in-differences [DD]=-7.8, 95% CI -21.1 to 5.5), 11- (DD=-13.9, 95% CI -27.7 to 0.04), or 17-month (DD=-8.2, 95% CI -22.0 to 5.7) time points, or when stratified by baseline recent drug use. However, those TWM-assigned participants with high overall levels of engagement (in the upper 25th percentile) were more likely to have an HIV UVL at the end of the 5-month active intervention period compared to those with low engagement (below the 75th percentile; risk difference=17.8, 95% CI 2.5-33.0) or no engagement (risk difference=19.4, 95% CI 3.3-35.5) in the intervention. Moreover, high engagement with the peer-to-peer exchange was associated with HIV UVL over time in unadjusted models.

CONCLUSIONS

TWM did not have overall impacts on HIV UVL; however, it may assist some sexual minority men who are highly engaged with this web-based intervention in achieving HIV viral suppression.

User Engagement With mHealth Interventions to Promote Treatment Adherence and Self-Management in People With Chronic Health Conditions: Systematic Review

BACKGROUND

There are numerous mobile health (mHealth) interventions for treatment adherence and self-management; yet, little is known about user engagement or interaction with these technologies.

OBJECTIVE

This systematic review aimed to answer the following questions: (1) How is user engagement defined and measured in studies of mHealth interventions to promote adherence to prescribed medical or health regimens or self-management among people living with a health condition? (2) To what degree are patients engaging with these mHealth interventions? (3) What is the association between user engagement with mHealth interventions and adherence or self-management outcomes? (4) How often is user engagement a research end point?

METHODS

Scientific database (Ovid MEDLINE, Embase, Web of Science, PsycINFO, and CINAHL) search results (2016-2021) were screened for inclusion and exclusion criteria. Data were extracted in a standardized electronic form. No risk-of-bias assessment was conducted because this review aimed to characterize user engagement measurement rather than certainty in primary study results. The results were synthesized descriptively and thematically.

RESULTS

A total of 292 studies were included for data extraction. The median number of participants per study was 77 (IQR 34-164). Most of the mHealth interventions were evaluated in nonrandomized studies (157/292, 53.8%), involved people with diabetes (51/292, 17.5%), targeted medication adherence (98/292, 33.6%), and comprised apps (220/292, 75.3%). The principal findings were as follows: (1) >60 unique terms were used to define user engagement; "use" (102/292, 34.9%) and "engagement" (94/292, 32.2%) were the most common; (2) a total of 11 distinct user engagement measurement approaches were identified; the use of objective user log-in data from an app or web portal (160/292, 54.8%) was the most common; (3) although engagement was inconsistently evaluated, most of the studies (99/195, 50.8%) reported >1 level of engagement due to the use of multiple measurement methods or analyses, decreased engagement across time (76/99, 77%), and results and conclusions suggesting that higher engagement was associated with positive adherence or self-management (60/103, 58.3%); and (4) user engagement was a research end point in only 19.2% (56/292) of the studies.

CONCLUSIONS

The results revealed major limitations in the literature reviewed, including significant variability in how user engagement is defined, a tendency to rely on user log-in data over other measurements, and critical gaps in how user engagement is evaluated (infrequently evaluated over time or in relation to adherence or self-management outcomes and rarely considered a research end point). Recommendations are outlined in response to our findings with the goal of improving research rigor in this area.

The impact of using reinforcement learning to personalize communication on medication adherence: findings from the REINFORCE trial

Text messaging can promote healthy behaviors, like adherence to medication, yet its effectiveness remains modest, in part because message content is rarely personalized. Reinforcement learning has been used in consumer technology to personalize content but with limited application in healthcare. We tested a reinforcement learning program that identifies individual responsiveness ("adherence") to text message content and personalizes messaging accordingly. We randomized 60 individuals with diabetes and glycated hemoglobin A1c [HbA1c] ≥ 7.5% to reinforcement learning intervention or control (no messages). Both arms received electronic pill bottles to measure adherence. The intervention improved absolute adjusted adherence by 13.6% (95%CI: 1.7%-27.1%) versus control and was more effective in patients with HbA1c 7.5- < 9.0% (36.6%, 95%CI: 25.1%-48.2%, interaction p < 0.001). We also explored whether individual patient characteristics were associated with differential response to tested behavioral factors and unique clusters of responsiveness. Reinforcement learning may be a promising approach to improve adherence and personalize communication at scale.

Adjunctive interventions: change methods directed at recipients that support uptake and use of health innovations

BACKGROUND

Implementation science groups change methods into two categories: (1) clinical, behavioral, or biomedical intervention targeting recipient's health outcomes and (2) implementation strategies targeting the delivery system. Differentiating interventions from strategies based on their intended functions is critical to accurately attributing their effects to health or implementation outcomes. However, in coordinating 200+ HIV implementation research projects and conducting systematic reviews, we identified change methods that had characteristics of both interventions and strategies that were inconsistently categorized. To alleviate confusion and improve change method specification, we propose that implementation science should adopt an extant but rarely used term-adjunctive interventions-to classify change methods that are distinct from the common intervention/strategy taxonomy.

MAIN TEXT

Adjunctive interventions as change methods that target recipients (e.g., patients, participants) of a health intervention but are designed to increase recipients' motivation, self-efficacy, or capacity for initiating, adhering to, complying with, or engaging with the health intervention over time. In two of our published reviews on implementation of HIV interventions, 25 out of 45 coded change methods fell into this gray area between strategy and intervention. We also noted instances in which the same change method was labelled as the intervention ("the thing"), as an adjunctive intervention, or an implementation strategy in different studies-further muddying the waters. Adjunctive interventions are distinguished from other change methods by their intended targets, desired outcomes, and theory of action and causal processes. Whereas health interventions target recipients and have a direct, causal effect on the health outcome, adjunctive interventions enhance recipients' attitudes and behaviors to engage with the intervention and have an indirect causal link to the health outcome via increasing the probability of recipients' utilization and adherence to the intervention. Adjunctive interventions are incapable of directly producing the health outcome and will themselves require implementation strategies to effectively impact sustained uptake, utilization, and adherence. Case examples, logic modeling, and considerations (e.g., relationship to consumer engagement strategies) for adjunctive intervention research are provided.

CONCLUSION

Conceptualizing adjunctive interventions as a separate type of change method will advance implementation research by improving tests of effectiveness, and the specification of mechanisms and outcomes.

Digital Solutions Observed in Clinical Trials: A Formative Feasibility Scoping Review

Growing digital access accelerates digital transformation of clinical trials where digital solutions (DSs) are increasingly and widely leveraged for improving trial efficiency, effectiveness, and accessibility. Many factors impact DS success including technology barriers, privacy concerns, or user engagement activities. It is unclear how those factors are considered or reported in the literature. Here, we perform a formative feasibility scoping review to identify gaps impacting DS quality and reproducibility in trials. Articles containing digital terms published in English from 2009 to 2022 were collected (n=4,167). 130 articles published between 2016 and 2022 were randomly selected for full-text review. Eligible articles (n=100) were sorted into four identified categories: 16% Education, 59% Intervention, 8% Patient, 17% Treatment. Initial findings about DS trends and reporting practices inform protocol development for a large-scale study urging the generation of fundamental knowledge on reporting standardization, best practice guidelines, and evaluation methodologies related to DS for clinical trials.

Supporting women's health outcomes after breast cancer treatment comparing a text message intervention to usual care: the EMPOWER-SMS randomised clinical trial

PURPOSE

The aim of this study is to evaluate the efficacy, feasibility and acceptability of a co-designed lifestyle-focused text message intervention (EMPOWER-SMS) for breast cancer survivors' self-efficacy, quality of life (QOL), mental (anxiety, depression, stress) and physical (endocrine therapy medication adherence, physical activity, BMI) health.

METHODS

Single-blind randomised controlled trial (1:1) comparing EMPOWER-SMS to usual care at 6-months (intention-to-treat).

SETTING

public Breast Cancer Institute (Sydney, Australia).

ELIGIBILITY CRITERIA

adult (> 18 years) females, < 18-months post-active breast cancer treatment (stage I-III), owned a mobile phone, written informed consent.

PRIMARY OUTCOME

Self-Efficacy for Managing Chronic Disease Scale at 6 months. Process data: message delivery analytics, cost, and post-intervention survey.

RESULTS

Participants (N = 160; mean age ± SD 55.1 ± 11.1 years) were recruited 29th-March-2019 to 7th-May-2020 and randomised (n = 80 EMPOWER-SMS: n = 80 control). Baseline mean self-efficacy was high (I: 7.1 [95%CI 6.6, 7.5], C: 7.4 [7, 7.8]). Six-month follow-up: no significant differences between groups for self-efficacy (I: 7.6 [7.3, 7.9], C: 7.6 [7.3, 7.9], adjusted mean difference 0 (95%CI 0.4, 0.4), QOL, mental health, physical activity, or BMI. Significantly less EMPOWER-SMS participants missed ≥ 1 endocrine therapy medication doses compared to control (I: 3/42[7.1%], C: 8/47[17.0%], Adjusted RR 0.13 [95%CI 0.02, 0.91]). Text messages were delivered successfully (7925/8061, 98.3%), costing $13.62USD/participant. Participants strongly/agreed EMPOWER-SMS was easy-to-understand (64/64; 100%), useful (58/64; 90.6%), motivating for lifestyle change (43/64; 67.2%) and medication adherence (22/46; 47.8%).

CONCLUSION

EMPOWER-SMS was feasible, inexpensive, acceptable for delivering health information to breast cancer survivors between medical appointments, with minor improvements in medication adherence.

IMPLICATIONS FOR CANCER SURVIVORS

Text messages offer a feasible strategy for continuity-of-care between medical appointments.

Successful Implementation Strategies in iCARE Nigeria-A Pilot Intervention with Text Message Reminders and Peer Navigation for Youth Living with HIV

To address poor outcomes among adolescents and young adults living with HIV (AYA-HIV), iCARE Nigeria successfully piloted two-way text message antiretroviral therapy (ART) reminders together with peer navigation. Study participants had significant improvement in ART adherence and viral suppression at 48 weeks. Understanding facto of this intervention. We used explanatory, mixed methods to assess implementation outcomes (feasibility, acceptability, and adoption) and identify implementation strategies used or adapted to promote intervention success. Quantitative data included participant surveys, program records, and back-end mHealth data, and were summarized using descriptive statistics. Qualitative data were collected from key informants and focus group discussions with program staff and summarized using directed content analysis. iCARE Nigeria was feasible as evidenced by ease of recruitment, high retention of patients and peer navigators (PN), and successful deployment of initial text message reminders (99.9%). Most participants (95%) and PN (90%) found text message reminders were not bothersome or intrusive. Implementation strategies employed to facilitate intervention success included: (1) selecting, training, supervising, and matching of PN to patients; (2) tailoring frequency (daily to weekly) and mode of communication between PN and patients according to patient need; (3) routine screening for adherence challenges; (4) changing phone airtime stipends from monthly to weekly in response to rapid depletion; and (5) conducting telecommunication needs assessments, to identify and troubleshoot implementation barriers (issues with mobile devices, power availability). iCARE Nigeria was feasible and acceptable with high adoption by stakeholders. The implementation strategies identified here can be tailored for intervention scale-up in similar environments to promote ART adherence for AYA-HIV.

Switching to bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) plus darunavir/cobicistat in heavily antiretroviral-experienced, virologically suppressed HIV-infected adults receiving complex regimens

OBJECTIVES

To evaluate the efficacy and safety of the two-pill regimen bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) plus darunavir/cobicistat as a switching strategy in heavily treatment-experienced people living with HIV (PLWH).

METHODS

Multicentre, prospective, single-arm pilot clinical trial. Participants were virologically suppressed adults receiving a stable antiretroviral regimen of at least three pills from at least three drug families due to previous virological failures and/or toxicities with no documented resistance to integrase strand transfer inhibitors or darunavir (≥15 points, Stanford). Clinical and laboratory assessments were performed at 0, 4, 12, 24, 36 and 48 weeks. HIV-1 proviral DNA was amplified and sequenced by Illumina at baseline. Plasma bictegravir concentrations were determined in 22 patients using UHPLC-MS/MS. The primary study endpoint was viral load (VL)< 50 copies/mL at Week 48 (ITT).

RESULTS

We enrolled 63 participants (92% men) with median baseline CD4 count of 515 cells/mm3 (IQR: 334.5-734.5), 24 years on ART (IQR: 15.9-27.8). The median number of pills was 4 (range: 3-10). At baseline, proviral DNA was amplified in 39 participants: 33/39 had resistance mutations. Three participants discontinued owing to toxicity. At 48 weeks, 95% had VL < 50 copies/mL by ITT and 100% by PP analysis. A modest increase was observed in the bictegravir plasma concentration, and a significant decrease in estimated glomerular filtration rate was observed only at Week 4, probably related to interaction with renal transporters.

CONCLUSIONS

Our data suggest that BIC/FTC/TAF + darunavir/cobicistat is an effective, well-tolerated regimen that may improve convenience and, potentially, long-term success in stable heavily pre-treated PLWH.

Projected Life Expectancy Gains From Improvements in HIV Care in Black and White Men Who Have Sex With Men

Importance

Substantial racial inequities exist across the HIV care continuum between non-Hispanic Black and White men who have sex with men (MSM) in the US.

Objectives

To project years of life gained (YLG) with improving the HIV care continuum among Black MSM and White MSM in the US and to determine the outcomes of achieving health equity goals.

Design, Setting, and Participants

The Cost-Effectiveness of Preventing AIDS Complications microsimulation model was used and populated with 2021 race-specific data to simulate HIV care among Black MSM and White MSM in the US who have acquired HIV. Analyses were completed from July 2021 to October 2023.

Intervention

The study simulated status quo care using race-specific estimates: age at infection, time to diagnosis, receipt of care, and virologic suppression. The study next projected the outcomes of attaining equity-centered vs non-equity-centered goals by simulating 2 equal improvements in care goals: (10-point increased receipt of care and 5-point increased virologic suppression), 3 equity-centered goals (annual HIV testing, 95% receiving HIV care, and 95% virologic suppression) and lastly, an equitable care continuum that achieves annual HIV testing, 95% receiving care, and 95% virologic suppression in Black MSM and White MSM. One-way and multiway sensitivity and scenario analyses were conducted.

Main Outcomes and Measures

Mean age at death and YLG.

Results

In the simulated cohort, the mean (SD) age at HIV infection was 27.0 (10.8) years for Black MSM and 35.5 (13.6) years for White MSM. In status quo, mean age at death would be 68.8 years for Black MSM and 75.6 years for White MSM. The equal improvements in care goals would result in 0.5 YLG for Black MSM and 0.5 to 0.9 YLG for White MSM. Achieving any 1 equity-centered goal would result in 0.5 to 1.7 YLG for Black MSM and 0.4 to 1.3 YLG for White MSM. With an equitable care continuum compared with the nationally reported status quo, Black MSM and White MSM would gain 3.5 and 2.1 life-years, respectively. If the status quo HIV testing was every 6 years with 75% retained in care and 75% virologically suppressed, Black MSM would gain 4.2 life-years with an equitable care continuum.

Conclusions and Relevance

In this simulation modeling study of HIV care goals, equal improvements in HIV care for Black and White MSM maintained or worsened inequities. These results suggest that equity-centered goals for the HIV care continuum are critical to mitigate long-standing inequities in HIV outcomes.

A randomized stepped wedge trial of an intensive combination approach to roll back the HIV epidemic in Nigerian adolescents: iCARE Nigeria treatment support protocol

BACKGROUND

Nigeria is one of six countries with half the global burden of youth living with HIV. Interventions to date have been inadequate as AIDS-related deaths in Nigeria's youth have remained unchanged in recent years. The iCARE Nigeria HIV treatment support intervention, a combination of peer navigation and SMS text message medication reminders to promote viral suppression, demonstrated initial efficacy and feasibility in a pilot trial among youth living with HIV in Nigeria. This paper describes the study protocol for the large-scale trial of the intervention.

METHODS

The iCARE Nigeria-Treatment study is a randomized stepped wedge trial of a combination (peer navigation and text message reminder) intervention, delivered to youth over a period of 48 weeks to promote viral suppression. Youth receiving HIV treatment at six clinical sites in the North Central and South Western regions of Nigeria were recruited for participation. Eligibility criteria included registration as a patient at participating clinics, aged 15-24 years, on antiretroviral therapy for at least three months, ability to understand and read English, Hausa, Pidgin English, or Yoruba, and intent to remain a patient at the study site during the study period. The six clinic sites were divided into three clusters and randomized to a sequence of control and intervention periods for comparison. The primary outcome is plasma HIV-1 viral load suppression, defined as viral load ≤ 200 copies/mL, in the intervention period versus the control period at 48 weeks of intervention.

DISCUSSION

Evidence-based interventions to promote viral load suppression among youth in Nigeria are needed. This study will determine efficacy of a combination intervention (peer navigation and text message reminder) and collect data on potential implementation barriers and facilitators to inform scale-up if efficacy is confirmed.

Feasibility and Acceptability of the Adherence Connection Counseling, Education, and Support (ACCESS) Proof of Concept: A Peer-Led, Mobile Health (mHealth) Cognitive Behavioral Antiretroviral Therapy (ART) Adherence Intervention for HIV-Infected (HIV+) Adolescents and Young Adults (AYA)

Effective antiretroviral therapy (ART) adherence strategies for HIV+ adolescents and young adults (AYA) are needed to prevent HIV-related morbidity, mortality, and onward transmission. In the Adherence Connection for Counseling, Education, and Support (ACCESS) pilot, an exploratory sequential mixed-methods design was used to develop and test a peer-led, mobile health (mHealth) cognitive behavioral ART adherence intervention. HIV+ AYA (ages 16-29 years) with unsuppressed plasma HIV RNA (HIV viral load) were eligible for this five-session intervention directed to improving ART adherence and HIV viral load. A total of 78 peer-led remote videoconferencing sessions (via WebEx) were delivered to 16 participants. High completion rates (97.5%) and client satisfaction scores (mean = 29.13 of 32; SD = 2.45) were observed. Self-reported ART adherence improved (32% increase in doses taken; 95th CI 11.2-53.3) with an annualized average rate of 47.5% (0.28 log10) reduction in HIV viral load. We established proof of concept for the ACCESS peer-led, mHealth cognitive behavioral ART adherence intervention, with promising adherence and virologic outcome data.

HIV viremia contributes to neurocognitive impairments in persons who use cocaine

Persons with HIV (PWH) who use illicit drugs are at elevated risk for neurocognitive impairment (NCI). This study investigated the effects of HIV disease and HIV viremia on NCI among adults who use cocaine. PWH who were not virologically suppressed showed greater global deficits compared to participants with HIV viral suppression and HIV-negative participants, but no differences emerged between the latter two groups. These findings highlight the adverse effects of poorly controlled HIV disease on NCI, beyond the independent effects of cocaine on cognition, and underscore the importance of strengthening the HIV care continuum for persons who use cocaine.

More than just Reminders: Using text Messaging to Improve HIV care Outcomes Among Youth and Young Adults Living with HIV

This study evaluated engagement, satisfaction, and efficacy of an automated and live two-way text messaging intervention that linked youth and young adults at high risk for poor HIV outcomes to their medical case managers, with the aims of increasing viral load suppression rates and improving medical visit attendance. Participants (N = 100) were an average age of 22-23 years old. Most were Black (93%) and men who have sex with men (82%). A total of 89,681 automated text messages were sent to participants; and 62% of participants engaged in monthly text-message exchanges with medical case managers. McNemar's test results indicated that a significantly greater proportion of intervention participants were virally suppressed at 6 and 12 month follow-up than at enrollment. Adjusted odds ratio results showed a significant association between likelihood of achieving viral suppression at 6 and 12 months, and a greater number of participant responses to automated text messages. Future research should prospectively compare outcomes between usual care case management and usual care plus text-messaging to test for significant differences between groups.

What is the Statin Possession Ratio Cut-Off Which Identifies Those at Increased Risk Following Acute Coronary Syndrome (ANZACS-QI 68)?

AIMS

More optimal dispensing of statins is associated with greater cholesterol lowering; however, it is not known whether this translates to improved outcomes following acute coronary syndrome (ACS). The aim of this study was to assess the association between various levels of statin adherence and outcomes following ACS.

METHODS

Patients hospitalised with ACS who underwent coronary angiography between 2014-2018 were identified from the All New Zealand ACS Quality Improvement (ANZACS-QI) registry. Medication possession ratio (MPR) was used to assess statin adherence and calculated over 1 year post-discharge using linked pharmaceutical dispensing datasets. Optimal, adequate and suboptimal adherence was defined as an MPR of ≥1.0, 0.8-0.99 and 0-0.79, respectively. A combined outcome of all-cause mortality and rehospitalisation for atherosclerotic disease was identified from 1 year post-discharge through September 2021. Cox proportional hazard models were used to adjust for confounding variables.

RESULTS

Of the 30,452 patients, 68% had optimal adherence, 15% adequate adherence and 16% had suboptimal adherence to statins. Mean follow-up was 3.6 years. Those with suboptimal adherence had a higher adjusted risk of the combined outcome compared with those with optimal adherence (HR 1.18, 95% CI 1.11-1.26). There was no significant difference in adjusted outcome between those with optimal and adequate adherence (HR 0.99, 95% CI 0.92-1.06).

CONCLUSIONS

Suboptimal statin adherence following ACS is associated with an increased risk of mortality and rehospitalisation. An MPR cut-off of 0.8 seems reasonable to identify those at higher risk of cardiovascular events that could benefit the most from interventions to improve statin adherence and is appropriate as a target for quality improvement programs.

Randomized Controlled Trial of Automated Directly Observed Therapy for Measurement and Support of PrEP Adherence Among Young Men Who have Sex with Men

Measurement of adherence to oral pre-exposure prophylaxis (PrEP) in real-time has been challenging. We developed DOT Diary, a smartphone application that combines automated directly observed therapy with a PrEP adherence visualization toolkit, and tested its ability to measure PrEP adherence and to increase adherence among a diverse cohort of young men who have sex with men (MSM). We enrolled 100 MSM in San Francisco and Atlanta and randomly assigned them 2:1 to DOT Diary versus standard of care. Concordance between DOT Diary measurement and drug levels in dried blood spots was substantial, with 91.0% and 85.3% concordance between DOT Diary and emtricitabine-triphosphate and tenofovir-diphosphate, respectively. There was no significant difference in the proportion of participants with detectable PrEP drug levels at 24 weeks between study arms. These results suggest DOT Diary is substantially better than self-reported measures of adherence, but additional interventions are needed to improve PrEP adherence over time.

Influencing medication taking behaviors using automated two-way digital communication: A narrative synthesis systematic review informed by the Behavior Change Wheel

PURPOSE

Around half of prescribed medications for long-term conditions are not taken as directed. Automated two-way digital communication, such as text messaging and interactive voice response technology, could deliver interventions to improve medication adherence, and subsequently health. However, exploration of how such interventions may improve medication adherence is limited. This review aimed to explore how automated two-way digital communication can improve medication taking with or without using non-digital intervention components, such as phone calls with healthcare professionals.

METHODS

A theory-informed narrative synthesis systematic review. Several databases were searched including CINAHL, Embase, Medline, and Web of Science using key words relating to 'medication adherence' and digital communication technologies. The Behavior Change Technique (BCT) coding using the BCT Taxonomy V1 and the Behavior Change Wheel were used to identify BCTs delivered within the included interventions.

RESULTS

A total of 3,018 records were screened with 43 study reports included in the review. Four medication-taking behaviors: taking medication, obtaining medication, self-testing, and asking for support were identified as targets for behavior change within the included interventions. Most BCTs within the digital communication component aimed to increase motivation for medication adherence, with non-digital intervention components included to address other medication taking barriers, such as physical and psychological capability.

CONCLUSION

Automated two-way digital communication can detect barriers to medication adherence by monitoring performance of the taking medication behavior. Monitoring outcomes from taking medication may increase reflective motivation to take medicines. Addressing physical opportunity to taking medication by facilitating the behavior obtaining medication may also increase adherence.

How Do Psychosocial Interventions for Adolescents and Young People Living With HIV Improve Adherence and Viral Load? A Realist Review

PURPOSE

Psychosocial interventions have the potential to support adolescents and young people living with HIV (AYPLHIV) to achieve better HIV outcomes. However, more evidence is needed to understand which interventions are most effective, and the mechanisms driving how they work in practice.

METHODS

We used realist methodologies to generate statements based on evidence from intervention studies and linked evidence included in a systematic review of psychosocial interventions for AYPLHIV. Key data were extracted from available sources to generate cases, including context-mechanism-outcome pathways. Higher level themes were refined iteratively to create a mid-range theory of how these interventions may work.

RESULTS

From 26 resulting cases, 8 statements were crafted, grouped into 3 overarching categories, to describe how these interventions worked. Interventions were overall found to set off mechanisms to improve adherence when (1) responding to individual-level factors to support AYPLHIV (via incorporating agency and empowerment, personalized and/or contextualized approaches, and self-care skills); (2) tailoring delivery strategies to address specific needs (via diverse strategies, longer duration, and digital delivery); and (3) providing supportive resources (via peer and broader support, and structural support and integration into existing services).

DISCUSSION

A collection of diverse mechanisms may individually or collectively drive improved outcomes for AYPLHIV engaged in psychosocial interventions. Recommendations for integrating our findings into practice are discussed.

Status-Neutral Interventions to Support Health Equity for Black Sexual Minority Men

PURPOSE OF REVIEW

Status-neutral care, a person-centered approach to healthcare not predicated on HIV serostatus, may improve health equity among Black sexual minority men (BSMM). We reviewed current status-neutral, HIV, and Pre-Exposure Prophylaxis (PrEP) interventions, and coded each for social-ecological focus and use of six approaches: (1) person-centered, (2) anti-stigma, (3) social support, (4) the social determinants of health (SDOH), (5) community engagement, and (6) multi-sectoral partnerships.

RECENT FINDINGS

We reviewed 25 studies, of which 3 were status-neutral. Nineteen studies utilized person-centered approaches, with several employing BSMM peers. For SDOH, financial incentives and reducing clinic-level barriers to care improved cascade outcomes. Direct text messaging, anti-stigma, social support, community-engagement, and multi-sectoral partnerships also improved outcomes in some studies. Few status-neutral programs exist and additional research is needed to identify key intervention components and mechanisms of influence. Programs targeting SDOH and multiple social-ecological levels offer promise for providing holistic care to BSMM, while addressing HIV prevention and treatment and health equity.

Developing a Consensus for Adolescent and Young Adult mHealth HIV Prevention Interventions in the United States: A Delphi Method Study

Background

Engaging adolescents and young adults (AYAs) who are at elevated risk for HIV acquisition or who are living with HIV in health care has posed a major challenge in HIV prevention and care efforts. Mobile health (mHealth) interventions are a popular and accessible strategy to support AYA engagement despite barriers to care present along the HIV care continuum. Even with progress in the field of mHealth research, expert recommendations for the process of designing, evaluating, and implementing HIV-related mHealth interventions are underdeveloped.

Objective

The aim of this study was to compile expert recommendations on the development, evaluation, and implementation of AYA-focused HIV prevention and care mHealth interventions.

Methods

Experts from adolescent mHealth HIV research networks and investigators of recently funded HIV mHealth projects and programs were identified and invited to complete a series of electronic surveys related to the design, implementation, and evaluation of HIV-related mHealth interventions. A modified Delphi method was used to ask experts to score 35 survey items on a 4-point Likert scale from not important to very important and encouraged experts to leave additional comments in textboxes. Responses were reviewed by the researchers, a team of 4 HIV mHealth intervention experts. The average importance ratings from survey responses were calculated and then categorized as retained (high importance), flagged (mid-level importance), or dropped (no/low importance). Additionally, thematic analysis of expert comments helped modify survey items for the next survey round. An evaluation of the level of agreement among experts on the most important items followed each round until consensus was reached.

Results

Of the 35 invited experts, 23 completed the first survey representing a variety of roles within a research team. Following two rounds of Delphi surveys, experts scored 24 of the 28 (86%) survey items included in round two as important to very important. The final consensus items included 24 recommendations related to the mHealth intervention design process (n=15), evaluation (n=2), and implementation (n=7). The 3 survey items with the highest average scores focused on the design process, specifically, (1) the creation of a diverse team including researchers, app software developers, and youth representation; (2) the importance of AYA-focused content; and (3) the value of an iterative process. Additionally, experts highlighted the importance of establishing the best ways to collect data and the types of data for collection during the evaluation process as well as constructing a plan for participant technology disruption when implementing an mHealth intervention.

Conclusions

The modified Delphi method was a useful tool to convene experts to determine recommendations for AYA-focused HIV prevention and care mHealth interventions. These recommendations can inform future mHealth interventions. To ensure the acceptability, feasibility, and efficacy of these AYA HIV prevention interventions, the focus must be on the specific needs of AYAs by including representation of AYAs in the process, including consistent and relevant content, ensuring appropriate data is collected, and considering technology and health accessibility barriers.

Psychosocial Interventions to Promote Undetectable HIV Viral Loads: A Systematic Review of Randomized Clinical Trials

Suppressing HIV viral loads to undetectable levels is essential for ending the HIV/AIDS epidemic. We evaluated randomized controlled trials aimed to increase antiretroviral medication adherence and promote undetectable viral loads among people living with HIV through November 22, 2019. We extracted data from 51 eligible interventions and analyzed the results using random effects models to compare intervention effects between groups within each intervention and across interventions. We also evaluated the relation between publication date and treatment effects. Only five interventions increased undetectable viral loads significantly. As a whole, the analyzed interventions were superior to Standard of Care in promoting undetectable viral loads. Interventions published more recently were not more effective in promoting undetectable viral loads. No treatment category consistently produced significant increases in undetectable viral loads. To end the HIV/AIDS epidemic, we should use interventions that can suppress HIV viral loads to undetectable levels.

The Effect of SMS Reminders on Adherence in a Self-Guided Internet-Delivered Intervention for Adults With ADHD

Background

Self-guided Internet-delivered interventions may serve as an accessible and flexible non-pharmacological treatment supplement for adults with ADHD. However, these interventions are challenged by low adherence.

Objective

To examine whether weekly SMS reminders improve adherence to a self-guided Internet-delivered intervention for adults with ADHD.

Method

The study used a multiple randomized trial design where the participants who had not completed their weekly module within 2 days were randomized to either receive or not receive an SMS reminder. The primary outcome was adherence, defined as module completion, logins, time spent on intervention, and self-reported practice of coping strategies.

Results

A total of 109 adults with a self-reported ADHD diagnosis were included in the study. The results showed that SMS reminders were associated with an increased likelihood of login within 48 h during the second module of the intervention, but not for the remaining modules. Moreover, receiving an SMS reminder was associated spending more time on the modules and faster login time in module three and five, specifically. However, the overall results did not show an effect of SMS reminders on module completion, number of logins or practice of coping strategies.

Conclusion

The results showed that SMS reminders do not improve number of logins, module completion rates or practice of coping strategies, but they may lead to faster login time and more time spent on the modules. To utilize the potential of self-guided Internet-delivered intervention in making non-pharmacological accessible for adults with ADHD, new methods to facilitate meaningful engagement should be developed and tested.

HIV pre-exposure prophylaxis adherence test using reverse transcription isothermal amplification inhibition assay

Current HIV antiretroviral therapy (ART) or pre-exposure prophylaxis (PrEP) therapy adherence monitoring relies on either patient self-reported adherence or monitored drug dispensing, which are not reliable. We report a proof-of-concept adherence monitoring assay which directly measures nucleotide reverse transcriptase inhibitor (NRTI) concentration using a reverse transcription isothermal amplification inhibition assay. We measure the concentration of Tenofovir diphosphate (TFV-DP) - an NRTI that functions as a deoxyadenosine triphosphate (dATP) analog and long-term adherence marker for PrEP - by measuring the inhibition of the reverse transcription of an RNA template. The completion or inhibition of reverse transcription is evaluated by recombinase polymerase amplification (RPA), an isothermal nucleic acid amplification assay commonly used for point-of-care diagnostics. We present and validate a model that predicts the amplification probability as a function of dATP and TFV-DP concentrations, nucleotide insertion sites on the RNA template, and RNA template concentration. The model can be used to rationally design and optimize the assay to operate at clinically relevant TFV-DP concentrations. We provide statistical analysis that demonstrates how the assay may be used as a qualitative or semi-quantitative tool for measuring adherence to NRTI drugs and used to support patient compliance. Due to its simple instrumentation and short runtime (<1 hour), this assay has the potential for implementation in low-complexity laboratories or point-of-care settings, which may improve access to ART and PrEP adherence monitoring.

A skills-based sero-status HIV disclosure intervention for sexual minority men in South Africa: A protocol for intervention adaptation and pilot randomized controlled trial (Preprint)

Background

Gay, bisexual, and other men who have sex with men (GBMSM) living with HIV have low antiretroviral treatment adherence in South Africa due to limited skills in managing disclosure and prevention behaviors with sexual and romantic partners. As a result, there is a high HIV transmission risk within HIV-discordant partnerships, but an existing intervention may address these outcomes, if adapted effectively. Healthy Relationships (HR) is a behavioral intervention that was originally delivered in groups and in person over 5 sessions to develop coping skills for managing HIV-related stress and sexually risky situations, enhance decision-making skills for HIV disclosure to partners, and establish and maintain safer sex practices with partners. HR effectively improves prevention behaviors but has yet to be tailored to a non-US context.

Objective

We aim to adapt HR into a new culturally grounded intervention entitled Speaking Out & Allying Relationships for GBMSM and then assess its feasibility in Eastern Cape, South Africa.

Methods

The study will have 2 aims. For aim 1—adaptation—we will use a human-centered design approach. Initial intervention tailoring will involve integrating Undetectable=Untransmittable and pre-exposure prophylaxis education, developing intervention content for a videoconference format, and designing role-plays and movies for skill building based on preliminary data. Afterward, interviews and surveys will be administered to GBMSM to assess intervention preferences, and a focus group will be conducted with health care providers and information technology experts to assess the intervention’s design. Finally, a usability test will be performed to determine functionality and content understanding. Participants will be GBMSM living with HIV (n=15) who are in a relationship and health care providers and information technology (n=7) experts working in HIV care and programming with this population. For aim 2, we will examine the feasibility of the adapted intervention by using a pilot randomized control design. There will be 60 individuals per arm. Feasibility surveys and interviews will be conducted with the intervention arm, and behavioral and biomedical assessments for relationship and treatment adherence outcomes will be collected for both arms. All participants will be GBMSM living with HIV who are in a relationship with an HIV-negative or unknown status partner.

Results

Intervention adaptation began in August 2021. Initial tailoring and the refining of GBMSM intervention preferences were completed in December 2021. Usability and feasibility assessments are due to be completed by March 2022 and February 2024, respectively.

Conclusions

GBMSM need efficacious interventions that tackle partnership dynamics, HIV prevention, and treatment outcomes for antiretroviral treatment adherence and viral suppression in South Africa. Harnessing everyday technology use for social networking (eg, videoconferences), Undetectable=Untransmittable education, and pre-exposure prophylaxis to update an existing intervention for South African GBMSM has the potential to strengthen relationship communication about HIV treatment and prevention and, in turn, improve outcomes.

Busting contraception myths and misconceptions among youth in Kwale County, Kenya: results of a digital health randomised control trial

OBJECTIVES

The objective of this randomised controlled trial in Kenya was to assess the effect of delivering sexual and reproductive health (SRH) information via text message to young people on their ability to reject contraception-related myths and misconceptions.

DESIGN AND SETTING

A three-arm, unblinded randomised controlled trial with a ratio of 1:1:1 in Kwale County, Kenya.

PARTICIPANTS AND INTERVENTIONS

A total of 740 youth aged 18-24 years were randomised. Intervention arm participants could access informational SRH text messages on-demand. Contact arm participants received once weekly texts instructing them to study on an SRH topic on their own. Control arm participants received standard care. The intervention period was 7 weeks.

PRIMARY OUTCOME

We assessed change myths believed at baseline and endline using an index of 10 contraception-related myths. We assessed change across arms using difference of difference analysis.

RESULTS

Across arms, <5% of participants did not have any formal education, <10% were living alone, about 50% were single and >80% had never given birth. Between baseline and endline, there was a statistically significant drop in the average absolute number of myths and misconceptions believed by intervention arm (11.1%, 95% CI 17.1% to 5.2%), contact arm (14.4%, 95% CI 20.5% to 8.4%) and control arm (11.3%, 95% CI 17.4% to 5.2%) participants. However, we observed no statistically significant difference in the magnitude of change across arms.

CONCLUSIONS

We are unable to conclusively state that the text message intervention was better than text message 'contact' or no intervention at all. Digital health likely has potential for improving SRH-related outcomes when used as part of multifaceted interventions. Additional studies with physical and geographical separation of different arms is warranted.

A Pilot Study of a Mobile Intervention to Support Mental Health and Adherence Among Adolescents Living with HIV in Western Kenya

Mobile technologies represent potentially novel and scalable intervention delivery platforms for adolescents living with HIV (ALWH) in low- and middle-income countries. We conducted a prospective, mixed methods pilot study to evaluate the acceptability and feasibility of the WhatsApp^® platform to deliver individual counseling services and facilitate peer support for ALWH in western Kenya. Thirty ALWH (17 female, mean age 15.4) on ART, engaged in HIV care and aware of their status, were enrolled. After 6 months, participants described their experiences with the intervention. Treatment adherence, stigma, and mental and behavioral health were assessed prospectively. Participants reported overall positive experiences and indicated that the platform encouraged peer network development. They endorsed potential benefits for treatment adherence, stigma reduction, and mental and behavioral health. All participants supported intervention expansion. In western Kenya, WhatsApp^® was an acceptable and feasible platform for mobile counseling and peer support for ALWH.

Behavioral Theories and Motivational Features Underlying eHealth Interventions for Adolescent Antiretroviral Adherence: Systematic Review

Background

eHealth systems provide new opportunities for the delivery of antiretroviral therapy (ART) adherence interventions for adolescents. They may be more effective if grounded in health behavior theories and behavior change techniques (BCTs). Prior reviews have examined the effectiveness, feasibility, and acceptability of these eHealth systems. However, studies have not systematically explored the use of health behavior theories and BCTs in the design of these applications.

Objective

The purpose of this review was to explore whether health behavior theories and BCTs were considered to ground designs of eHealth systems supporting adolescents’ (10-24 years) ART adherence. More specifically, we examined which specific theories and BCTs were applied, and how these BCTs were implemented as design features. Additionally, we investigated the quality and effect of eHealth systems.

Methods

A systematic search was performed on IEEE Xplore, ACM, ScienceDirect, PubMed, Scopus, and Web of Science databases from 2000 to 2020. Theory use and BCTs were coded using the Theory Coding Scheme and the Behavior Change Technique Taxonomy version 1 (BCTTv1), respectively. Design features were identified using the lenses of motivational design for mobile health (mHealth). The number of BCTs and design features for each eHealth system and their prevalence across all systems were assessed.

Results

This review identified 16 eHealth systems aiming to support ART adherence among adolescents. System types include SMS text message reminders (n=6), phone call reminders (n=3), combined SMS text message and phone call reminders (n=1), electronic adherence monitoring devices (n=3), smartphone apps (n=1), smartphone serious games (n=1), gamified smartphone apps (n=1), leveraging existing social media (n=2), web-based applications (n=1), videoconferencing (n=1), and desktop applications (n=1). Nine were grounded in theory, of which 3 used theories extensively. The impact of adolescent developmental changes on ART adherence was not made explicit. A total of 42 different BCTs and 24 motivational design features were used across systems. Ten systems reported positive effects on 1 or more outcomes; however, of these ten systems, only 3 reported exclusively positive effects on all the outcomes they measured. As much as 6 out of 16 reported purely no effect in all the outcomes measured.

Conclusions

Basic applications (SMS text messaging and phone calls) were most frequent, although more advanced systems such as mobile apps and games are also emerging. This review indicated gaps in the use of theory and BCTs, and particularly the impact of developmental changes on ART adherence was not adequately considered. Together with adopting a developmental orientation, future eHealth systems should effectively leverage health theories and consider developing more advanced systems that open the door to using BCTs more comprehensively. Overall, the impact of eHealth systems on adolescent ART adherence and its mediators is promising, but conclusive evidence on effect still needs to be provided.

HIV care continuum interventions for Black men who have sex with men in the USA

Disparities persist along the HIV care continuum among Black men who have sex with men (MSM) in the USA. As part of an initiative funded by the Health Resources and Services Administration's HIV/AIDS Bureau (US Department of Health and Human Services), we searched for recently published interventions focused on improving HIV care continuum outcomes among Black MSM with HIV in the USA. Our search identified 14 interventions, all of which were associated with at least one statistically significant outcome. Medication adherence was the most common outcome of interest, and linkage to care was the least common. More than half of the interventions focused on younger populations and took place in the US South. Interventions used a range of strategies to increase cultural relevance and address common barriers to optimal HIV outcomes for Black MSM. Several interventions harnessed social media, text messaging, and smartphone apps to facilitate social support, deliver HIV education, and encourage medication adherence. Interventions were delivered mostly at the individual or interpersonal level, although three made system-level changes to address structural barriers. Notably missing were interventions focused on minimising behavioural health barriers, and interventions directly addressing social determinants of health such as housing. To accelerate the pace of implementation and scale-up of interventions for Black MSM with HIV, public health entities can pilot emerging interventions in real-world settings, and use an implementation science approach to evaluate outcomes and assess the implementation strategies that drive or hinder effectiveness.

Adaptation of evidence-based approaches to promote HIV testing and treatment engagement among high-risk Nigerian youth

Background

Nigeria has the second highest number of people living with HIV (PLWH) globally, and evidence-based approaches are needed to achieve national goals to identify, treat, and reduce new infections. Youth between the ages of 15–24, including young men who have sex with men (YMSM), are disproportionately impacted by the Nigerian HIV epidemic. The purpose of this study was to inform adaptation of evidence-based peer navigation and mHealth approaches (social media outreach to promote HIV testing; short messaging service text message reminders to promote HIV treatment engagement) to the local context within iCARE Nigeria, a multi-phase study designed to investigate combination interventions to promote HIV testing and care engagement among youth in Nigeria.

Methods

To elicit expert and community perspectives, a local group of advisors from academia, community, and governmental sectors provided feedback on intervention adaptation, which then informed a series of focus groups with stakeholders in Ibadan, Nigeria. Focus group data were collected over a period of three days in December of 2018. Participants in focus groups included YMSM and HIV-positive youth in care ages 16–24, and HIV service providers from local AIDS service organizations (ASO). Groups were stratified by HIV serostatus, gender, and stakeholder type. Focus group sessions were conducted using a semi-structured interview guide, audio-recorded, transcribed verbatim, and analyzed using a content analysis approach.

Results

Local experts recommended intervention adaptations specific to the status of peer navigators as volunteers, peer characteristics (slightly older age, high maturity level, HIV/YMSM status), and intervention characteristics and resources (low navigator to peer ratio; flexible matching by demographic and social characteristics; social media platforms and content). Five focus group discussions with stakeholders, including 27 participants were conducted to elicit feedback on these and other potential adaptations. Youth participants (n = 21) were mean age 20 years (range = 16–24); 76% HIV-positive, 76% men and 48% MSM. Service providers (n = 6) represented both HIV prevention and care services. Participants across stratified subgroups reported largely positive perceptions and high perceived acceptability of both mHealth and peer navigation strategies, and echoed the recommendations of the advisory group for volunteer-based navigators to promote altruism, with a low navigator-peer ratio (1:5). Participants emphasized the need to incorporate minimal mobile data use strategies and popular social media platforms among YMSM (e.g., Facebook, Grindr) for widespread access and reach of the interventions.

Conclusions

In Ibadan, Nigeria, stakeholders support the adaptation of combined mHealth and peer navigation strategies to promote HIV testing and care engagement among high-risk youth. Recommended adaptations for the local context reflect concerns about the feasibility and sustainability of the intervention and are expected to improve accessibility and acceptability.

Preventing Medication Nonadherence of Youth (13-24 Years) With HIV Initiating Antiretroviral Therapy

PURPOSE

The objective of this study was to evaluate the feasibility and acceptability of a dynamic, behavioral intervention to optimize medication adherence of adolescents and young adults (AYAs) with HIV newly initiating highly active antiretroviral therapy (HAART) and explore its efficacy on adherence and disease outcomes.

METHODS

The two-arm randomized controlled trial piloted a brief, individualized intervention designed for direct integration into standard clinical care. In total, 32 AYAs with a confirmed HIV diagnosis, reportedly horizontally acquired, and recommended to initiate HAART completed a two-week placebo trial before HAART initiation and were subsequently randomized to standard of care or the individualized intervention. Adherence and disease outcomes were measured over the first six months of HAART.

RESULTS

Results supported the primary study aim regarding feasibility (recruitment = 89%, attendance = 81%-100%, intervention exercise completion = 100%) and acceptability (average favorable response = 89%). Data also supported the positive effect of the intervention on select HAART adherence measures and disease outcomes. Adherence (by pharmacy refill) declined in both groups; however, adherence declined more slowly in the intervention group versus standard of care (p < .001). In addition, 100% of participants receiving the intervention obtained an undetectable viral load by 3 months and maintained an undetectable viral load at 6 months (vs. 68.8% standard of care).

CONCLUSIONS

This is one of the first interventions to target adherence for AYAs with HIV newly initiating HAART and designed for delivery in existing clinical care settings. Future research will help confirm efficacy and the potential utility of the intervention in promoting HAART adherence from medication initiation and preventing the decrease in adherence often observed over time.

A Review of Interventions to Enhance HIV Medication Adherence

PURPOSE OF REVIEW

Adherence to antiretroviral treatment (ART) is crucial for the successful treatment of HIV. Unfortunately, it is estimated that 45% of persons living with HIV (PLWH) have poor adherence to ART. To provide health care professionals and PLWH with effective tools for supporting adherence, researchers have investigated the effectiveness of psychosocial interventions to enhance adherence to ART. In this paper, interventional studies, systematic reviews, and meta-analyses that examine ART adherence interventions for PLWH are reviewed.

RECENT FINDINGS

There is great variability among interventions in terms of quality, sample, measures, and outcome characteristics. Despite a diverse and wide-ranging assortment of ART adherence interventions, consistent lessons have been learned. Interventions that focus on individual and interpersonal factors have been effective for improving ART adherence; however, the improvement in adherence tends to be short-lived. Additionally, interventions are most successful when tailored to those at risk for poor adherence. Finally, theory-based interventions are more likely to be effective than non-theory-based interventions. A variety of individual-level psychological interventions have been shown to be effective in improving ART adherence in the short term. Digital and mobile interventions have the potential to improve dissemination and implementation of these evidence-based interventions and could be used to extend intervention effects. Future interventions that address issues of accessibility, inequality, structural and institutional barriers to ART adherence should also be tested and prioritized. Implementation science frameworks can be used to assess and address issues of accessibility and systematic barriers to care.

Modeling Adherence Interventions Among Youth with HIV in the United States: Clinical and Economic Projections

The Adolescent Medicine Trials Network for HIV/AIDS Interventions is evaluating treatment adherence interventions (AI) to improve virologic suppression (VS) among youth with HIV (YWH). Using a microsimulation model, we compared two strategies: standard-of-care (SOC) and a hypothetical 12-month AI that increased cohort-level VS in YWH in care by an absolute ten percentage points and cost $100/month/person. Projected outcomes included primary HIV transmissions, deaths and life-expectancy, lifetime HIV-related costs, and incremental cost-effectiveness ratios (ICERs, $/quality-adjusted life-year [QALY]). Compared to SOC, AI would reduce HIV transmissions by 15% and deaths by 12% at 12 months. AI would improve discounted life expectancy/person by 8 months at an added lifetime cost/person of $5,300, resulting in an ICER of $7,900/QALY. AI would be cost-effective at $2,000/month/person or with efficacies as low as a 1 percentage point increase in VS. YWH-targeted adherence interventions with even modest efficacy could improve life expectancy, prevent onward HIV transmissions, and be cost-effective.

Text Messaging Improves HIV Care Continuum Outcomes Among Young Adult Trans Women Living with HIV: Text Me, Girl!

Young adult trans women living with HIV in the US exhibit suboptimal advancement through the HIV Care Continuum relative to national averages. From December 2016 through May 2018, 134 young adult trans women living with HIV enrolled in Text Me, Girl!, a theory-based, trans-specific text-messaging intervention designed to improve HIV Care Continuum outcomes. Participants (N = 130) averaged 29.5 years, were predominantly Latinx (43%) or African American/Black (40%). Clustered logistic and ordinal logistic multivariable models (n = 105; 366 observations) indicate that through 18-month follow-up, increased exposure to the text-messaging intervention was associated with significant (p < 0.05) increased retention to HIV care (adjusted odds ratio [aOR] 1.33) and biomarker-confirmed viral suppression (aOR 1.51); retention in the intervention was associated with significantly increased likelihood of ART uptake (aOR 2.95) and "excellent" ART adherence (aOR 10.44). Text Me, Girl! offers promising evidence that a unidirectional, automated text-messaging intervention can improve HIV care outcomes among young adult trans women living with HIV.

Psychosocial interventions for improving engagement in care and health and behavioural outcomes for adolescents and young people living with HIV: a systematic review and meta-analysis

INTRODUCTION

Adolescents and young people comprise a growing proportion of new HIV infections globally, yet current approaches do not effectively engage this group, and adolescent HIV-related outcomes are the poorest among all age groups. Providing psychosocial interventions incorporating psychological, social, and/or behavioural approaches offer a potential pathway to improve engagement in care and health and behavioural outcomes among adolescents and young people living with HIV (AYPLHIV).

METHODS

A systematic search of all peer-reviewed papers published between January 2000 and July 2020 was conducted through four electronic databases (Cochrane Library, PsycINFO, PubMed and Scopus). We included randomized controlled trials evaluating psychosocial interventions aimed at improving engagement in care and health and behavioural outcomes of AYPLHIV aged 10 to 24 years.

RESULTS AND DISCUSSION

Thirty relevant studies were identified. Studies took place in the United States (n = 18, 60%), sub-Saharan Africa (Nigeria, South Africa, Uganda, Zambia, Zimbabwe) and Southeast Asia (Thailand). Outcomes of interest included adherence to antiretroviral therapy (ART), ART knowledge, viral load data, sexual risk behaviours, sexual risk knowledge, retention in care and linkage to care. Overall, psychosocial interventions for AYPLHIV showed important, small-to-moderate effects on adherence to ART (SMD = 0.3907, 95% CI: 0.1059 to 0.6754, 21 studies, n = 2647) and viral load (SMD = -0.2607, 95% CI -04518 to -0.0696, 12 studies, n = 1566). The psychosocial interventions reviewed did not demonstrate significant impacts on retention in care (n = 8), sexual risk behaviours and knowledge (n = 13), viral suppression (n = 4), undetectable viral load (n = 5) or linkage to care (n = 1) among AYPLHIV. No studies measured transition to adult services. Effective interventions employed various approaches, including digital and lay health worker delivery, which hold promise for scaling interventions in the context of COVID-19.

CONCLUSIONS

This review highlights the potential of psychosocial interventions in improving health outcomes in AYPLHIV. However, more research needs to be conducted on interventions that can effectively reduce sexual risk behaviours of AYPLHIV, as well as those that can strengthen engagement in care. Further investment is needed to ensure that these interventions are cost-effective, sustainable and resilient in the face of resource constraints and global challenges such as the COVID-19 pandemic.

Effect of Text Messaging Plus Peer Navigation on Viral Suppression Among Youth With HIV in the iCARE Nigeria Pilot Study

BACKGROUND

Consistent with the global trend, youth with HIV (YWH) in Nigeria have high rates of viral nonsuppression. Hence, novel interventions are needed.

SETTING

Infectious Diseases Institute, College of Medicine, University of Ibadan, Nigeria.

METHODS

In a single-arm trial, participants aged 15-24 years received 48 weeks of a combination intervention, comprising daily 2-way text message medication reminders plus peer navigation. The primary outcome measure was viral suppression less than 200 copies/mL. The secondary outcome measures included self-reported adherence on a visual analog scale and medication possession ratio, each dichotomized as ≥90% (good) or <90% (poor) adherence. The outcomes were analyzed using McNemar test. Retention in care, intervention feasibility and acceptability, and participants' satisfaction were also assessed.

RESULTS

Forty YWH (50% male participants) were enrolled: mean age 19.9 years (SD = 2.5), 55% perinatally infected, and 35% virologically suppressed at baseline. Compared with baseline, the odds of virologic suppression was higher at 24 weeks (odds ratio = 14.00, P < 0.001) and 48 weeks (odds ratio = 6.00, P = 0.013). Self-reported adherence (≥90%) increased from baseline at 24 weeks (63%, P = 0.008) and 48 weeks (68%, P = 0.031). Medication possession ratio ≥90% increased at weeks 24 and 48 (85% and 80%, respectively), achieving statistical significance at 24 weeks alone (P = 0.022). Retention in care at 48 weeks was 87.5%. All (37/37) participants at week 48 were fully or mostly satisfied with the intervention.

CONCLUSION

Daily 2-way text message reminders plus peer navigation is a promising combination intervention to improve viral suppression among YWH in Nigeria.

Testing Digital Methods of Patient-Reported Outcomes Data Collection: A prospective, cluster randomized trial to test text messaging and mobile surveys. (Preprint)

Background

Health care delivery continues to evolve, with an effort being made to create patient-centered care models using patient-reported outcomes (PROs) data. Collecting PROs has remained challenging and an expanding landscape of digital health offers a variety of methods to engage patients.

Objective

The aim of this study is to prospectively investigate two common methods of remote PRO data collection. The study sought to compare response and engagement rates for bidirectional SMS text messaging and mobile surveys following orthopedic surgery.

Methods

The study was a prospective, block randomized trial of adults undergoing elective orthopedic procedures over 6 weeks. The primary objective was to determine if the method of digital patient engagement would impact response and completion rates. The primary outcome was response rate and total completion of PRO questionnaires.

Results

A total of 127 participants were block randomized into receiving a mobile survey (n=63) delivered as a hyperlink or responding to the same questions through an automated bidirectional SMS text messaging system (n=64). Gender, age, number of comorbidities, and opioid prescriptions were similar across messaging arms. Patients receiving the mobile survey were more likely to have had a knee-related surgery (n=50, 83.3% vs n=40, 62.5%; P=.02) but less likely to have had an invasive procedure (n=26, 41.3% vs n=39, 60.9%; P=.03). Overall engagement over the immediate postoperative period was similar. Prolonged engagement for patients taking opioids past postoperative day 4 was higher in the mobile survey arm at day 7 (18/19, 94.7% vs 9/16, 56.3%). Patients with more invasive procedures showed a trend toward being responsive at day 4 as compared to not responding (n=41, 59.4% vs n=24, 41.4%; P=.05).

Conclusions

As mobile patient engagement becomes more common in health care, testing the various options to engage patients to gather data is crucial to inform future care and research. We found that bidirectional SMS text messaging and mobile surveys were comparable in response and engagement rates; however, mobile surveys may trend toward higher response rates over longer periods of time.

Acceptability of a Mobile Phone Support Tool (Call for Life Uganda) for Promoting Adherence to Antiretroviral Therapy Among Young Adults in a Randomized Controlled Trial: Exploratory Qualitative Study

Background

Adherence to treatment is critical for successful treatment outcomes. Although factors influencing antiretroviral therapy (ART) adherence vary, young adults are less likely to adhere owing to psychosocial issues such as stigma, ART-related side effects, and a lack of access to treatment. The Call for Life Uganda (CFLU) mobile health (mHealth) tool is a mobile phone–based technology that provides text messages or interactive voice response functionalities through a web interface and offers 4 modules of support.

Objective

This study aims to describe the acceptability and feasibility of a mobile phone support tool to promote adherence to ART among young adults in a randomized controlled trial.

Methods

An exploratory qualitative design with a phenomenological approach at 2 study sites was used. A total of 17 purposively selected young adults with HIV infection who had used the mHealth tool CFLU from 2 clinics were included. In total, 11 in-depth interviews and 1 focus group discussion were conducted to examine the following topics: experience with the CFLU tool (benefits and challenges), components of the tool, the efficiency of the system (level of comfort, ease, or difficulty in using the system), how CFLU resolved adherence challenges, and suggestions to improve CFLU. Participants belonged to 4 categories of interest: young adults on ART for the prevention of mother-to-child transmission, young adults switching to or on the second-line ART, positive partners in an HIV-discordant relationship, and young adults initiating the first-line ART. All young adults had 12 months of daily experience using the tool. Data were analyzed using NVivo version 11 software (QSR International Limited) based on a thematic approach.

Results

The CFLU mHealth tool was perceived as an acceptable intervention; young adults reported improvement in medication adherence, strengthened clinician-patient relationships, and increased health knowledge from health tips. Appointment reminders and symptom reporting were singled out as beneficial and helped to address the problems of forgetfulness and stigma-related issues. HIV-related stigma was reported by a few young people. Participants requested extra support for scaling up CFLU to make it more youth friendly. Improving the tool to reduce technical issues, including network outages and a period of software failure, was suggested. They suggested that in addition to digital solutions, other support, including the promotion of peer support meetings and the establishment of a designated space and staff members for youth, was also important.

Conclusions

This mHealth tool was an acceptable and feasible strategy for improving ART adherence and retention among young adults in resource-limited settings.

A Single-Blind, Parallel Design RCT to Assess the Effectiveness of SMS Reminders in Improving ART Adherence Among Adolescents Living with HIV (STARTA Trial)

PURPOSE

The study evaluated the feasibility, acceptability, and efficacy of interactive and tailored short message reminders on antiretroviral therapy adherence among adolescents (15-19 years) living with HIV in southwest Nigeria.

METHODS

The study was a single-blind, parallel-design (ratio 1:1), and multicenter RCT of 209 medication-non-adherent adolescents living with HIV at HIV clinics in two states in southwest Nigeria. The research assessed ART adherence using the visual analog scale, viral suppression, pill count, and ACTG scores; the feasibility of the intervention by the SMS delivery and response (overall and individual) rates; and acceptability using self-report, willingness to continue receiving the intervention, and desire for its scale-up.

RESULTS

A total of 17,690 text messages were sent while 10,119 (57.2%) got delivered to the participants. Out of 9,216 responses that were received from the study participants, 8,781 (95.3%) indicated acceptability of the intervention. The end-of-study log₁₀ of viral load values between control and intervention groups had a mean difference of 0.66 (95% CI 0.26-1.06) and p-value of .001. Also, the unadjusted odds ratio of undetected viral load (≤20 copies/ml) was 1.356 (1.039-1.771) with a p-value of .002. However, the intervention had no effect on subjective measures of antiretroviral therapy adherence.

CONCLUSIONS

The use of interactive and tailored short message reminders to enhance antiretroviral therapy adherence among adolescents has good potential. It seems feasible, highly acceptable, and possibly leads to improved viral load count. It is likely that the associated antiretroviral therapy adherence enhances viral suppression and, therefore, improves outcomes in adolescent HIV.

Pregnancy in an Urban Cohort of Adolescents Living with Human Immunodeficiency Virus: Characteristics and Outcomes in Comparison to Adults

Adolescents (13-24 years of age) account for more than one-fifth of new HIV diagnoses yearly, and the United States has one of the highest rates of adolescent pregnancy among high resource countries. However, there is limited information on the characteristics and outcomes of adolescents living with HIV (ALWHIV) during pregnancy and differences with pregnancy in adults living with HIV. We performed a retrospective cohort study to compare demographic characteristics, HIV viral suppression, and pregnancy outcomes in adolescents (n = 90) as compared with adults (n = 250) in an urban HIV pregnancy clinic from 2003 to 2015. Seventy-one women overall were diagnosed with HIV during pregnancy (adolescents, 25/90; adults, 46/250). One-fifth of adolescents acquired HIV perinatally. Adolescents were more likely than adults to have unintended pregnancy (83.6% vs. 68.7%, p = 0.016) and were less likely to be virally suppressed at delivery (50.0% vs. 69.7% overall, p = 0.001; 48.0% vs. 78.2% in postuniversal antiretroviral therapy era, p = 0.007%). Over one-third of adolescents reported a history of any illicit substance use, and adolescents were more likely than adults to use marijuana during pregnancy (29.2% vs. 16.9%, p = 0.013). Adolescents were less likely to experience preterm labor (11.0% vs. 24.1%, p = 0.012) or preterm premature rupture of membranes (3.7% vs. 16.7%, p = 0.003). There was one case of maternal-fetal transmission, which occurred in an adult pregnancy. Despite the high rate of unintended pregnancy, one-third of adolescents were discharged without an identified contraception plan. We identify several opportunities for intervention to improve reproductive health outcomes in ALWHIV.

Toward improved adherence: a text message intervention in an human immunodeficiency virus pediatric clinic in Guatemala City

As access to human immunodeficiency virus treatment expands in Low to Middle Income Countries, it becomes critical to develop and test strategies to improve adherence and ensure efficacy. Text messaging improves adherence to antiretroviral treatment antiretroviral treatment in some patient populations, but data surrounding the use of these tools is sparse in pediatric and adolescent patients in low to middle income countries. We evaluated if a text message intervention can improve antiretroviral treatment adherence while accounting for cell phone access, patterns of use, and willingness to receive text messages.We carried out a cross sectional study to understand willingness of receiving text message reminders, followed by a randomized controlled trial to assess effectiveness of text message intervention.Enrolled participants were randomized to receive standard care with regular clinic visits, or standard care plus short message service reminders. Adherence was measured 3 times during the study period using a 4-day Recall Questionnaire. Outcome was measured based on differences in the average adherence between the intervention and control group at each time point (baseline, 3 months, 6 months).Most respondents were willing to receive text message adherence reminders (81.1%, n = 53). Respondent literacy, travel time to clinic, cell phone access, and patterns of use were significantly associated with willingness. In the randomized trial the intervention group (n = 50) experienced a small but significant mean improvement in adherence over the six-month period (4%, P < .01) whereas the control group (n = 50) did not (mean improvement: 0.8%, P = .64).Text message interventions effectively support antiretroviral adherence in pediatric patients living with human immunodeficiency virus. Studies designed to assess the impact of text messaging interventions must examine local context for cellular phone infrastructure and use and must account for potential loss to follow up when patients miss appointments and study assessments.

Patient-Reported Opioid Consumption and Pain Intensity After Common Orthopedic and Urologic Surgical Procedures With Use of an Automated Text Messaging System

Importance

Surgeons must balance management of acute postoperative pain with opioid stewardship. Patient-centered methods that immediately evaluate pain and opioid consumption can be used to guide prescribing and shared decision-making.

Objective

To assess the difference between the number of opioid tablets prescribed and the self-reported number of tablets taken as well as self-reported pain intensity and ability to manage pain after orthopedic and urologic procedures with use of an automated text messaging system.

Design, Setting, and Participants

This quality improvement study was conducted at a large, urban academic health care system in Pennsylvania. Adult patients (aged ≥18 years) who underwent orthopedic and urologic procedures and received postoperative prescriptions for opioids were included. Data were collected prospectively using automated text messaging until postoperative day 28, from May 1 to December 31, 2019.

Main Outcomes and Measures

The primary outcome was the difference between the number of opioid tablets prescribed and the patient-reported number of tablets taken (in oxycodone 5-mg tablet equivalents). Secondary outcomes were self-reported pain intensity (on a scale of 0-10, with 10 being the highest level of pain) and ability to manage pain (on a scale of 0-10, with 10 representing very able to control pain) after orthopedic and urologic procedures.

Results

Of the 919 study participants, 742 (80.7%) underwent orthopedic procedures and 177 (19.2%) underwent urologic procedures. Among those who underwent orthopedic procedures, 384 (51.8%) were women, 491 (66.7%) were White, and the median age was 48 years (interquartile range [IQR], 32-61 years); 514 (69.8%) had an outpatient procedure. Among those who underwent urologic procedures, 145 (84.8%) were men, 138 (80.7%) were White, and the median age was 56 years (IQR, 40-67 years); 106 (62%) had an outpatient procedure. The mean (SD) pain score on day 4 after orthopedic procedures was 4.72 (2.54), with a mean (SD) change by day 21 of -0.40 (1.91). The mean (SD) ability to manage pain score on day 4 was 7.32 (2.59), with a mean (SD) change of -0.80 (2.72) by day 21. The mean (SD) pain score on day 4 after urologic procedures was 3.48 (2.43), with a mean (SD) change by day 21 of -1.50 (2.12). The mean (SD) ability to manage pain score on day 4 was 7.34 (2.81), with a mean (SD) change of 0.80 (1.75) by day 14. The median quantity of opioids prescribed for patients who underwent orthopedic procedures was high compared with self-reported consumption (20 tablets [IQR, 15-30 tablets] vs 6 tablets used [IQR, 0-14 tablets]), similar to findings for patients who underwent urologic procedures (7 tablets [IQR, 5-10 tablets] vs 1 tablet used [IQR, 0-4 tablets]). Over the study period, 9452 of 15 581 total tablets prescribed (60.7%) were unused. A total of 589 patients (64.1%) used less than half of the amount prescribed, and 256 patients (27.8%) did not use any opioids (179 [24.1%] who underwent orthopedic procedures and 77 [43.5%] who underwent urologic procedures).

Conclusions and Relevance

In this quality improvement study of adult patients reporting use of opioids after common orthopedic and urologic surgical procedures through a text messaging system, the quantities of opioids prescribed and the quantity consumed differed. Patient-reported data collected through text messaging may support clinicians in tailoring prescriptions and guide shared decision-making to limit excess quantities of prescribed opioids.

Poor quality of life and incomplete self-reported adherence predict second-line ART virological failure in resource-limited settings

We evaluated health-related quality of life (QoL) and self-reported incomplete adherence as predictors of early second-line antiretroviral (ART) virological failure (VF). ACTG A5273 study participants completed the ACTG SF-21 measure which has 8 QoL domains. We used exact logistic regression to assess the association of QoL at baseline and week 4 with early VF adjusted for self-reported adherence. Of 500 individuals (51% women, median age 39 years) in this analysis, 79% and 75% self-reported complete adherence (no missing doses in the past month) at weeks 4 and 24, respectively. Early VF was experienced by 7% and more common among those who self-reported incomplete adherence. Participants with low week 4 QoL scores had higher rates of early VF than participants with high scores. After adjusting for self-reported adherence at week 4, VL and CD4 at baseline, cognitive functioning, pain and mental health domains were significantly associated with subsequent early VF. In this post-hoc analysis, poorer QoL adds to self-reported incomplete adherence after 4 weeks of second-line ART in predicting VF at week 24. Evaluation is needed to assess whether individuals with poorer QoL might be targeted for greater support to reduce risk of VF.Trial registration: ClinicalTrials.gov identifier: NCT01352715.

Implementation Science Protocol: evaluating evidence-informed interventions to improve care for people with HIV seen in Ryan White HIV/AIDS program settings

In 2017, the Health Resources and Services Administration's HIV/AIDS Bureau funded an Evaluation Center (EC) and a Coordinating Center for Technical Assistance (CCTA) to oversee the rapid implementation of 11 evidence-informed interventions at 26 HIV care and treatment providers across the U.S. This initiative aims to address persistent gaps in HIV-related health outcomes emerging from social determinants of health that negatively impact access to and retention in care. The EC adapted the Conceptual Model of Implementation Research to develop a Hybrid Type III, multi-site mixed-methods evaluation, described in this paper. The results of the evaluation will describe strategies associated with uptake, implementation outcomes, as well as HIV-related health outcomes for clients engaged in the evidence-informed interventions. This approach will allow us to understand in detail the processes that sites undergo to implement these important intervention strategies for high priority populations.

The ongoing HIV epidemic in American youth: challenges and opportunities

The incidence of human immunodeficiency virus (HIV) infection has been decreasing in the United States overall, except among youth, and in particular among Black and Latinx young men who have sex with men (MSM). In this review we summarize key drivers of the HIV epidemic among youth, as well as novel interventions geared specifically towards combating the epidemic among high-risk populations. Many factors driving the HIV epidemic among youth are related to systemic inequities, including lack of access to healthcare, inadequate education, and internalized and experience homophobia and racism. Developmentally, youth may feel that they are invulnerable and be willing to engage in risks. Moreover, HIV is often invisible for youth given advances in treatment and community stigma, limiting open discussion of risk and new preventive modalities. Outcomes from the HIV treatment cascade suggest that youth are less likely to be aware of their HIV infection status, less likely to link to and be engaged in care, and less likely to be virologically suppressed than older MSM and other populations of people living with HIV. Importantly, pre-exposure prophylaxis (PrEP) has been shown to be an effective tool for prevention of HIV infection that also appears to have disproportionately poor uptake among youth. Barriers to PrEP utilization appear to be quite heterogeneous, and include patient-, provider-, and structural-level barriers. Interventions important in improving HIV prevention will thus have to be multipronged and developed for culturally diverse populations. Cognitive behavioral therapy-based interventions are promising strategies as they are able to address a diverse array of barriers. New formulations of PrEP will also likely be instrumental in improving adherence. Since youth spend considerable amounts of time accessing digital media, the deployment of apps and other mobile phone-based interfaces offer unique opportunities to increase education and to facilitate HIV prevention for at risk youth. Multiple studies are underway to better inform the optimal delivery of treatment and prevention services for this complex and diverse population, and include novel sociobiological interventions and new modes of medication delivery that may lend themselves to overcoming obstacles specific to youth.

Microenterprise Intervention to Reduce Sexual Risk Behaviors and Increase Employment and HIV Preventive Practices Among Economically-Vulnerable African-American Young Adults (EMERGE): A Feasibility Randomized Clinical Trial

Economic vulnerability, such as homelessness and unemployment, contributes to HIV risk among U.S. racial minorities. Yet, few economic-strengthening interventions have been adapted for HIV prevention in this population. This study assessed the feasibility of conducting a randomized clinical trial of a 20-week microenterprise intervention for economically-vulnerable African-American young adults. Engaging MicroenterprisE for Resource Generation and Health Empowerment (EMERGE) aimed to reduce sexual risk behaviors and increase employment and uptake of HIV preventive behaviors. The experimental group received text messages on job openings plus educational sessions, mentoring, a start-up grant, and business and HIV prevention text messages. The comparison group received text messages on job openings only. Primary feasibility objectives assessed recruitment, randomization, participation, and retention. Secondary objectives examined employment, sexual risk behaviors, and HIV preventive behaviors. Outcome assessments used an in-person pre- and post-intervention interview and a weekly text message survey. Several progression criteria for a definitive trial were met. Thirty-eight participants were randomized to experimental (n = 19) or comparison group (n = 19) of which 95% were retained. The comparison intervention enhanced willingness to be randomized and reduced non-participation. Mean age of participants was 21.0 years; 35% were male; 81% were unemployed. Fifty-eight percent (58%) of experimental participants completed ≥ 70% of intervention activities, and 74% completed ≥ 50% of intervention activities. Participation in intervention activities and outcome assessments was highest in the first half (~ 10 weeks) of the study. Seventy-one percent (71%) of weekly text message surveys received a response through week 14, but responsiveness declined to 37% of participants responding to ≥ 70% of weekly text message surveys at the end of the study. The experimental group reported higher employment (from 32% at baseline to 83% at week 26) and lower unprotected sex (79% to 58%) over time compared to reported changes in employment (37% to 47%) and unprotected sex (63% to 53%) over time in the comparison group. Conducting this feasibility trial was a critical step in the process of designing and testing a behavioral intervention. Development of a fully-powered effectiveness trial should take into account lessons learned regarding intervention duration, screening, and measurement.Trial Registration ClinicalTrials.gov.

ART Adherence Among Men Who Have Sex with Men Living with HIV: Key Challenges and Opportunities

PURPOSE OF REVIEW

In the USA, gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. High levels of adherence to antiretroviral therapy (ART) can dramatically improve outcomes for persons living with HIV and reduce the risk of HIV transmission to others. Yet, there are numerous individual, social, and structural barriers to optimal ART adherence. Many of these factors disproportionately impact Black MSM and may contribute to their poorer rates of ART adherence. This review synthesizes the key challenges and intervention opportunities to improve ART adherence among MSM in the USA.

RECENT FINDINGS

Key challenges to ART adherence include stigma, violence, depression, and substance use. Black MSM are significantly disadvantaged by several of these factors. There are several promising interventions to improve ART adherence among MSM, and there remains an opportunity to culturally tailor these to the needs of Black MSM populations to enhance adherence. Despite high rates of HIV among MSM, there continues to be a paucity of research on the various contributors to poor ART adherence among this population. Similarly, few interventions have been tested that lead to increased and sustained ART adherence among Black MSM.
