Measuring engagement in HIV care: Measurement invariance in three racial/ethnic patient groups

Medical mistrust of health systems as a moderator of resilience and self-reported HIV care engagement in Black and Latinx young adults living with HIV

OBJECTIVE

To study resilience and its association with HIV care engagement in a sample of young adult Black and Latinx people living with HIV (PLWH) in the United States and to test if a systems-level barrier, medical mistrust, would moderate the resilience-engagement association.

METHOD

Between April and August 2021, we recruited participants through social media and dating apps (N = 212) and verified age and HIV status through a review process of digital text-messaged and emailed photos. Participants completed a one-time online survey consisting of the Connor-Davidson Resilience Scale, The Index of Engagement in HIV Care, and the Medical Mistrust Index. We ran a regression-based moderation analysis using the Johnson-Neyman Technique to estimate regions of significance.

RESULTS

The sample (N = 212) was 80.5% Black and 19.5% Latinx with a mean age of 25.8 years (SD = 2.84). Higher resilience scores were associated with higher HIV care engagement scores (b = 0.72, p = .003), and medical mistrust moderated this relationship as evidenced by a mistrust by resilience interaction (b = -0.16, p = .01). Our regions of statistical significance showed that as mistrust increased, the size of the resilience-engagement association decreased.

CONCLUSION

Resilience may be a protective factor associated with greater participation and sense of connection to HIV care, but is diminished by mistrust of the medical system at large. This suggest that systems-level changes, in addition to individual-level interventions, are needed to address medical mistrust to fully harness the resilience of young PLWH.

Engagement in Care, Awareness, and Interest in Long-Acting Injectable Anti-Retroviral Therapy

Long Acting Injectable (LAI) therapy to treat HIV is an alternative to daily oral medications. The success of early roll-out of LAI to eligible patients requires a better understanding of patients' awareness and interest in this novel therapy. We administered an electronic survey to patients attending an urban HIV clinic in the US South. Eligible participants were 18 + years old with a most recent HIV-1 viral load < 200 copies/ml, without any evidence of genotypic resistance to LAI components or chronic hepatitis B. Survey recipients were asked about current treatment, engagement in care, and knowledge of LAI. Between January-April 2023, 480 patients were screened; 319 were eligible, and 155 (49%) completed the survey. The majority (119, 77%) were aware of, and 87 (56%) were interested in LAI. In regression analysis, only age was associated with interest in LAI (OR 0.95, 95% CI 0.92,0.99). Among proposed benefits of injectables, ease of travel without pills, lack of daily pill-taking, and fewer medication interactions were most appealing. Among proposed concerns with injectables, higher cost and insurance coverage of the new medicine were most worrisome. A large majority of people with HIV (PWH) are aware of the newest treatment available, and just over half of our sample expressed interest in LAI. Older age was associated with lower interest in LAI. LAI is appealing for its convenience, privacy, and avoidance of drug interactions, while the increased costs associated with LAI need to be addressed.

The HIV Index Is Associated With Retention in Care Among Latinx Persons Living With HIV in the CFAR Network of Integrated Clinical Systems Cohort

The HIV Index is a validated self-report scale of engagement in HIV care previously correlated with future retention and virologic suppression. However, its performance in a monoethnic Latinx population has not been studied. We evaluated the HIV Index among Latinx persons living with HIV in the Centers for AIDS Research Network of Integrated Clinical Systems cohort and performed multivariable logistic regression to estimate its association with primary outcomes of suboptimal retention (not keeping 100% of HIV clinic appointments) and virologic suppression (HIV viral load <200 copies/mL). The mean Index score was 4.5 (standard deviation 0.6) in both analytic samples, indicative of feeling well-engaged. Higher Index scores were associated with lower odds of suboptimal retention (OR = 0.12, 95% CI [0.03, 0.54], p = .005), however, there was no association between Index score and virologic suppression. The HIV Index is useful for assessing engagement and retention among Latinx PLWH in routine care.

Assessing the Impact of Social Determinants of Health on HIV Care Engagement in the Southern United States: A Cross-Sectional Study

Recent studies have shown social determinants of health (SDOH) to impact HIV care engagement. This cross-sectional study (Oct 20-Apr 21) assessed the impact of a range of SDOH on HIV care engagement using data from HIV Care Connect, a consortium of three HIV care facility-led programs (Alabama, Florida, Mississippi). The exposures were captured using the PRAPARE (Protocol for Responding to and Assessing Patient Assets, Risks, and Experiences) scale. The outcome was captured using the Index of Engagement in HIV Care scale. Participants (n  =  132) were predominantly non-White (87%) and male (52%) with a median age of 41 years. Multivariable logistic regression adjusted for various sociodemographics showed lower HIV care engagement to be associated with being uninsured/publicly insured, having 1-3 unmet needs, socially integrating ≤five times/week, and having stable housing. Factors such as unmet needs, un-/underinsurance, and social integration may be addressed by healthcare and community organizations.

The Brief Human Immunodeficiency Virus (HIV) Index: A Rapid 3-Item Scale to Measure Engagement in HIV Care

We created a brief version of The Index, a validated patient-reported measure that has potential to quickly identify patients at risk for poor retention. We analyzed Index scores from 2406 patients from 2016 to 2017 in a national cohort of patients in human immunodeficiency virus (HIV) care. Index scores predicted poor retention 12 months after administered.

Suubi + Adherence4Youth: a study protocol to optimize the Suubi Intervention for Adherence to HIV treatment for youth living with HIV in Uganda

BACKGROUND

Suubi is an evidenced based multi-component intervention that targets psychosocial and economic hardships to improve ART adherence, viral suppression, mental health, family financial stability, and family cohesion for adolescents living with HIV (ALHIV) in Uganda. Suubi was originally tested as a combined package of four components: 1) Financial Literacy Training; 2) incentivized matched Youth Savings Accounts with income-generating activities; 3) a manualized and visual-based intervention for ART adherence and stigma reduction; and 4) engagement with HIV treatment-experienced role models. However, it is unknown if each component in Suubi had a positive effect, how the components interacted, or if fewer components could have produced equivalent effects. Hence, the overall goal of this new study is to identify the most impactful and sustainable economic and psychosocial components across 48 health clinics in Uganda.

METHODS

A total of 576 ALHIV (aged 11-17 years at enrollment) will be recruited from 48 clinics and each clinic will be randomized to one of 16 study conditions. Each condition represents every possible combination of the 4 components noted above. Assessments will be conducted at baseline, 12, 24, 36 and 48- months post-intervention initiation. Using the multi-phase optimization strategy (MOST), we will identify the optimal combination of components and associated costs for viral suppression, as well as test key mediators and moderators of the component-viral suppression relationship.

DISCUSSION

The study is a shift in the paradigm of research to use new thinking to build/un-pack highly efficacious interventions that lead to new scientific knowledge in terms of understanding what drives an intervention's success and how to iterate on them in ways that are more efficient, affordable and scalable. The study advances intervention science for HIV care outcomes globally.

A New Attitude Towards Treatment Measure Predicts Survival Over 17 Years

BACKGROUND

For patients diagnosed with chronic illness, attitude towards treatment may play an important role in health and survival. For example, negative attitudes towards treatment have been related to poorer adherence to treatment recommendations and prescribed medication across a range of chronic illnesses. In addition, prior research has shown that attitude towards treatment assessed through a psychiatric interview predicted survival at 1 year after bone marrow transplantation with great accuracy (> 90%).

OBJECTIVE

The purpose of this study was to determine the relationship between a self-report attitude to a treatment measure that operationalized a psychiatric interview, and survival over 17 years in a sample of people living with HIV (PLWH).

PARTICIPANTS AND DESIGN

Participants (N = 177) who were in the mid-range of HIV illness at baseline (CD4s 150 to 500, no prior AIDS-defining clinical symptom) were administered the Montreal-Miami Attitude to Treatment (MMAT-20/HIV) scale and followed longitudinally to determine survival at 17 years.

MEASURES

The Montreal-Miami Attitude to Treatment (MMAT-20/HIV) scale is a 20-item self-report questionnaire designed to survey multiple factors that contribute to an overall psychological construct of the treatment process.

RESULTS

The MMAT-20/HIV predicted survival over 17 years controlling for biomedical (baseline CD4, viral load, antiretroviral medications, age) and psychosocial (race, education, antiretroviral medications) variables. Those in the top half on the MMAT-20/HIV were almost twice as likely to survive than those in the lower half. Scores on the MMAT-20/HIV were significantly but modestly correlated with adherence (r = .20, p < .05), but adherence was not a mediator of the relationship between the MMAT-20/HIV and survival.

CONCLUSIONS

An individual's attitude towards the treatment process predicted survival, raising the possibility that optimal clinical management would include ways to probe these attitudes and intervene where possible. The ease of administering the MMAT-20 and adaptability to other illnesses could facilitate this endeavor.
