Improving Viral Load Suppression Among Men and Children Active in Care Through Community-Designed and Led Solutions: Protocol for Retrospective Closed Cohort Study in Eastern Uganda.

BackgroundIn collaboration with facilities, communities, district local government, and the United States Agency for International Development (USAID) implementing partners, the iDARE methodology was implemented at the community level to address root causes of low HIV antiretroviral therapy adherence among men and children actively enrolled in care, resulting in low viral load suppression (VLS) in two districts in the eastern region of Uganda. The methodology encourages the use of cocreated sustainable solutions addressing gender, youth, and social inclusion issues to reduce barriers to care and reach the 95-95-95 Joint United Nations Programme on HIV/AIDS target for HIV epidemic control. We aim to measure the impact of iDARE on VLS for men and children active in care and investigate the practical scale up of the solutions designed using the iDARE methodology.ObjectiveThe primary objective of this study will be to measure the implementation impact of the iDARE methodology at the facility and community levels on VLS for people living with HIV. The secondary objective is to investigate the practical scale up of the iDARE methodology using evidence-based gender, youth, and social inclusion social behavior change packages to rapidly meet the Ugandan Ministry of Health targets for VLS.MethodsA retrospective cohort study design will be used to analyze program data that aims to increase the rates of VLS in men and children who are classified as active in care using community engagement and quality improvement techniques. We will examine 3 pilot health centers’ data from a USAID-funded program aimed at social behavior change to increase health-seeking behavior in Uganda. Based on the iDARE process and results, change packages were developed to highlight lessons learned and best practices in order to share with subsequent implementation sites.ResultsThe USAID-funded Social and Behavior Change Activity began implementation of iDARE in September 2020, with baseline data collected in August 2020.ConclusionsData on viral load suppression was collected from facilities on a monthly basis to record progress toward the 95-95-95 goal. The expected primary outcome is an increase in actively enrolled men and children reaching VLS in order to meet the Ugandan Ministry of Health target of 95% VLS among those active in care.International Registered Report Identifier (IRRID)DERR1-10.2196/32784

The Situated Information, Motivation, and Behavioral Skills Model of HIV Antiretroviral Therapy Adherence Among Persons Living With HIV in Haiti: A Qualitative Study Incorporating Culture and Context.

To inform a clinic-based adherence-promotion intervention, this qualitative study applied the Situated Information, Motivation, and Behavioral Skills Model of Care Initiation and Maintenance to elucidate cultural and contextual factors affecting antiretroviral therapy adherence in Haiti. From the 23 focus group discussions with patients ( n = 58) and health care workers ( n = 57), culturally specific themes emerged relating to Information (e.g., conflicts with allopathic medicine and heuristics about how treatment failure occurs), Motivation (e.g., protecting family members, health and physical appearance, material advantages, and relationships with health workers), and Behavioral Skills (e.g., managing food intake and side effects, navigating health services utilization, accessing medication, and advocating for care needs). Recommendations include: provide therapeutic education on HIV drug resistance; promote the concept of "undetectable = untransmittable"; develop treatment buddy relationships; invest in training and enforcement of patient privacy, transparency, and fairness in access to services and resources; and provide patient-centered behavioral skills counseling.

Virtual voices: examining social support exchanged through participant-generated and unmoderated content in a mobile intervention to improve HIV antiretroviral therapy adherence among GBMSM

ABSTRACT Antiretroviral therapy (ART) adherence is suboptimal among gay, bisexual, and other men who have sex with men (GBMSM). Online interventions that incorporate social support represent new opportunities to improve adherence. This study focused on how social support was provided and sought within a technology-based ART adherence intervention. We coded and analyzed 1,751 messages. Within the social support messages, half of the time participants sought social support and half of the time they provided social support. Emotional and informational support were the most frequently exchanged forms. The most frequent topic that participants sought support around was interpersonal relationships (29%), followed by HIV care and treatment (28%). Similarly, 31% and 27% of messages in which participants provided support was related to HIV treatment and care and interpersonal relationships, respectively. HIV treatment and care issues most salient were ART adherence, lab results and upcoming tests, ART side effects, changes in ART regimens, and relationships with healthcare providers. Participants used the messaging feature in this intervention to spontaneously discuss and exchange support around HIV treatment and care. This analysis provided an opportunity to understand how participants informally interact with one another, how they seek and provide social support online, and their salient personal issues.

The impact of an integrated health-system specialty pharmacy on HIV antiretroviral therapy adherence, viral suppression and CD4 count in an outpatient ID clinic

Background: Atrium Health (AH) is a Charlotte-based not for profit hospital network that currently cares for HIV-infected patients through three outpatient ID clinics. AH recognized that novel approaches to patient care which incorporate clinical pharmacists and health-system specialty pharmacy into the practice model can help improve the HIV continuum. As a result, AH created an HIV specialty pharmacy service line that embedded an HIV-trained clinical pharmacist and pharmacy technician within one of three health-system outpatient ID clinics. Aims: This study aimed to evaluate the antiretroviral medication adherence rate, viral load, and CD4 count among patients utilizing Atrium Health Specialty Pharmacy Service (AH SPS) compared to patients that opted out of the program. Methods: This was a single-center, retrospective cohort study conducted from 7 August 2017 to 30 June 2018. All patients were already on HIV therapy at either entry or declination to the AH SPS program. The intervention group was defined as HIV patient care that incorporated AH SPS into the practice model. The control group was defined as HIV patient care that did not involve our health-system specialty pharmacy. The primary endpoints were medication adherence, viral suppression, and CD4 counts. Adherence was measured using pharmacy claims data and the Medication Possession Ratio (MPR) calculation. Baseline viral load and CD4 count at the time of entry or declination to the program was recorded as well as at the end of the observation period. Comparisons between the opt-in and opt-out groups were made. Results: For those patients using AH SPS, the overall average adherence rate was 100% versus only 89% for those patients that opted out of the service (p < 0.01). Furthermore, all but 3 patients using AH SPS reached viral suppression (p = 0.03) and all but one had improved immunefunction with a CD4 count 200 or greater by the end of the observation period (p = 0.03). The change in viral suppression and CD4 count of 200 or greater was not statistically improved between baseline and follow up in those opting out of using AH SPS. Conclusions: The AH SPS utilized an innovative practice model that fully integrated a specialty pharmacy team within an outpatient ID clinic. This novel approach to patient care significantly improved adherence which in turn lead to improved viral suppression and immune markers in patients enrolled within the program compared to those opting out.

The association of provider and practice factors with HIV antiretroviral therapy adherence.

While antiretroviral therapy (ART) is essential to patients with HIV, there is substantial variation in adherence nationally. We assess how provider and practice factors contribute to successful HIV ART adherence. We used Medicaid Analytic Extract claims from 2008 to 2012. We attributed patients with HIV to the provider that provided the plurality of HIV-related services or primary care in a given year and assigned these providers to a medical practice based on the National Provider Identifier registry file. We fit successive linear hierarchical models with patient, provider, and practice characteristics to partition the variation in adherence driven by each factor. Our unit of analysis was the patient-year. Fourteen US states with the highest HIV prevalence. A total of 111 013 patient-years representing 60 496 Medicaid enrollees living with HIV attributed to 4930 providers and 1960 practices. Percentage of year individual patients were adherent to an ART regimen. Provider and practice random effects jointly explained 6.8% of variation in adherence with patient differences accounted for 45.2% of the variation. Patients seen by generalists and other specialists had a 1.6 [95% confidence interval (CI): 0.6-2.5] and 5.1 (95% CI: 4.1-6.1) percentage point greater adherence than those seen by infectious disease specialists (P < 0.001). Every additional year a patient saw the same provider was associated with a 6% increase in adherence (95% CI: 5.7-6.3). There is substantial variation in ART adherence attributable to providers and practices and between provider specialties. To improve ART adherence for patients living with HIV, structural aspects of care should be considered.

A Pilot Study of a Mobile App to Support HIV Antiretroviral Therapy Adherence Among Men Who Have Sex with Men Who Use Stimulants.

APP+ is a theoretically-grounded mobile app intervention to improve antiretroviral (ART) adherence among men who have sex with men (MSM) who use stimulants. We assessed the feasibility and acceptability of APP+ in a six-month randomized controlled trial among a national sample of 90 MSM recruited online; secondarily, we examined changes in self-reported ART adherence by study arm. Retention at the final assessment was 82%, and acceptability ratings were comparable to other technology-based interventions. MSM in the APP+ group reported higher self-reported percentage ART adherence in the past 30days at the four-month timepoint compared to a no-treatment control group (89.0% vs. 77.2%). However, once access to the app was removed after month four, group differences in ART adherence diminished by month six. APP+ may be a potentially promising intervention approach for MSM living with HIV who use stimulants but would require enhancements to optimize acceptability and demonstrate more sustained effects.

Delivery of HIV Antiretroviral Therapy Adherence Support Services by HIV Care Providers in the United States, 2013 to 2014.

Little is known about clinicians' adoption of recommendations of the International Association of Providers of AIDS Care and others for supporting adherence to antiretroviral therapy (ART). We surveyed a probability sample of US HIV care providers to estimate the percentage offering 3 ART adherence support services to most or all patients and assessed the characteristics of providers offering all 3 services (comprehensive support) to most or all patients. Almost all providers (95.5%) discussed ART adherence at every visit, 60.1% offered advice about tools to increase adherence, 53.5% referred nonadherent patients for supportive services, and 42.8% provided comprehensive support. Nurse practitioners were more likely to offer comprehensive support as were providers who practiced at Ryan White HIV/AIDS Program-funded facilities, provided primary care, or started caring for HIV-infected patients within 10 years. Less than half of HIV care providers offered comprehensive ART adherence support. Certain subgroups may benefit from interventions to increase delivery of adherence support.

Assessment of HIV antiretroviral therapy adherence by measuring drug concentrations in hair among children in rural Uganda

Current tools for measuring medication adherence have significant limitations, especially among pediatric populations. We conducted a prospective observational study to assess the use of antiretroviral (ARV) drug levels in hair for evaluating antiretroviral therapy (ART) adherence among HIV-infected children in rural Uganda. Three-day caregiver recall, 30-day visual analog scale (VAS), Medication Event Monitoring System (MEMS), and unannounced pill counts and liquid formulation weights (UPC) were collected monthly over a one-year period. Hair samples were collected quarterly and analyzed for nevirapine (NVP) levels, and plasma HIV RNA levels were collected every six months. Among children with at least one hair sample collected, we used univariable random intercept linear regression models to compare log transformed NVP concentrations with each adherence measure, and the child's age, sex, and CD4 count percentage (CD4%). One hundred and twenty-one children aged 2–10 years were enrolled in the study; 74 (61%) provided at least one hair sample, and the mean number of hair samples collected per child was 1.9 (standard deviation [SD] 1.0). Three-day caregiver recall, VAS, and MEMS were found to be positively associated with increasing NVP concentration in hair, although associations were not statistically significant. UPC was found to have a nonsignificant negative association with increasing hair NVP concentration. In conclusion, NVP drug concentrations in hair were found to have nonsignificant, although generally positive, associations with other adherence measures in a cohort of HIV-infected children in Uganda. Hair collection in this population proved challenging, suggesting the need for community education and buy-in with the introduction of novel methodologies.

Namibian prisoners describe barriers to HIV antiretroviral therapy adherence

Little is available in scholarly literature about how HIV-positive prisoners, especially in low-income countries, access antiretroviral therapy (ART) medication. We interviewed 18 prisoners at a large prison in Namibia to identify barriers to medication adherence. The lead nurse researcher was a long-standing clinic employee at the prison, which afforded her access to the population. We identified six significant barriers to adherence, including (1) the desire for privacy and anonymity in a setting where HIV is strongly stigmatized; (2) the lack of simple supports for adherence, such as availability of clocks; (3) insufficient access to food to support the toll on the body of ingesting taxing ART medications; (4) commodification of ART medication; (5) the brutality and despair in the prison setting, generally leading to discouragement and a lack of motivation to strive for optimum health; and (6) the lack of understanding about HIV, how it is transmitted, and how it is best managed. Because most prisoners eventually transition back to communitysettings when their sentences are served, investments in prison health represent important investments in public health.

Associations between the legal context of HIV, perceived social capital, and HIV antiretroviral adherence in North America.

BackgroundHuman rights approaches to manage HIV and efforts to decriminalize HIV exposure/transmission globally offer hope to persons living with HIV (PLWH). However, among vulnerable populations of PLWH, substantial human rights and structural challenges (disadvantage and injustice that results from everyday practices of a well-intentioned liberal society) must be addressed. These challenges span all ecosocial context levels and in North America (Canada and the United States) can include prosecution for HIV nondisclosure and HIV exposure/transmission. Our aims were to: 1) Determine if there were associations between the social structural factor of criminalization of HIV exposure/transmission, the individual factor of perceived social capital (resources to support one’s life chances and overcome life’s challenges), and HIV antiretroviral therapy (ART) adherence among PLWH and 2) describe the nature of associations between the social structural factor of criminalization of HIV exposure/transmission, the individual factor of perceived social capital, and HIV ART adherence among PLWH.MethodsWe used ecosocial theory and social epidemiology to guide our study. HIV related criminal law data were obtained from published literature. Perceived social capital and HIV ART adherence data were collected from adult PLWH. Correlation and logistic regression were used to identify and characterize observed associations.ResultsAmong a sample of adult PLWH (n = 1873), significant positive associations were observed between perceived social capital, HIV disclosure required by law, and self-reported HIV ART adherence. We observed that PLWH who have higher levels of perceived social capital and who live in areas where HIV disclosure is required by law reported better average adherence. In contrast, PLWH who live in areas where HIV transmission/exposure is a crime reported lower 30-day medication adherence. Among our North American participants, being of older age, of White or Hispanic ancestry, and having higher perceived social capital, were significant predictors of better HIV ART adherence.ConclusionsTreatment approaches offer clear advantages in controlling HIV and reducing HIV transmission at the population level. These advantages, however, will have limited benefit for adherence to treatments without also addressing the social and structural challenges that allow HIV to continue to spread among society’s most vulnerable populations.

Cannabis use and HIV antiretroviral therapy adherence and HIV-related symptoms

Occasional cannabis use has been associated with increased antiretroviral therapy (ART) adherence and relief of HIV symptoms, while heavy use has been associated with low ART adherence and negative psychological symptoms. The purpose of the present study was to investigate differences between non-cannabis use (NC), non-dependent cannabis use (C), and dependent use (CD) in terms of ART adherence and HIV symptoms/ART side effects. A cross-sectional sample of 180 HIV+ individuals (78.3% male) completed measures of substance use and psychopathology, medication adherence, and HIV symptoms/ART side effects. Adherence was also measured via pill count, viral load, and CD4 count. Results indicated that the CD group reported lower adherence and greater HIV symptoms/ART side effects than the other two groups, with no differences observed between NC and C groups. There is a clinical need to address dependent cannabis use among those prescribed ART. Further examination is needed to ascertain the functions of cannabis use among individuals with HIV.

The Costs of HIV Antiretroviral Therapy Adherence Programs and Impact on Health Care Utilization

From a trial comparing interventions to improve adherence to antiretroviral therapy-directly administered antiretroviral therapy (DAART) or an intensive adherence case management (IACM)-to standard of care (SOC), for HIV-infected participants at public HIV clinics in Los Angeles County, California, we examined the cost of adherence programs and associated health care utilization. We assessed differences between DAART, IACM, and SOC in the rate of hospitalizations, hospital days, and outpatient and emergency department visits during an average of 1.7 years from study enrollment, beginning November 2001. We assigned costs to health care utilization and program delivery. We calculated incremental costs of DAART or IACM v SOC, and compared those costs with savings in health care utilization among participants in the adherence programs. IACM participants experienced fewer hospital days compared with SOC (2.3 versus 6.7 days/1000 person-days, incidence rate ratio [IRR]: 0.34, 97.5% confidence interval [CI]: 0.13-0.87). DAART participants had more outpatient visits than SOC (44.2 versus 31.5/1000 person-days, IRR: 1.4; 97.5% CI: 1.01-1.95). Average per-participant health care utilization costs were $13,127, $8,988, and $14,416 for DAART, IACM, and SOC, respectively. Incremental 6-month program costs were $2,120 and $1,653 for DAART and IACM participants, respectively. Subtracting savings in health care utilization from program costs resulted in an average net program cost of $831 per DAART participant; and savings of $3,775 per IACM participant. IACM was associated with a significant decrease in hospital days compared to SOC and was cost saving when program costs were compared to savings in health care utilization.
