Why do Integrated Maternal HIV and Infant Healthcare Services work? A Secondary Analysis of a Randomised Controlled Trial in South Africa. AIDS Behav 2023; 27:3831-3843. [PMID: 37306847 PMCID: PMC10598190 DOI: 10.1007/s10461-023-04097-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/20/2023] [Indexed: 06/13/2023]
Abstract
In a randomised trial, we found that integrated maternal HIV and infant health services through the end of breastfeeding were significantly associated with the primary outcome of engagement in HIV care and viral suppression at 12 months postpartum, compared to the standard of care. Here, we quantitatively explore potential psychosocial modifiers and mediators of this association. Our findings suggest that the intervention was significantly more effective among women experiencing an unintended pregnancy but did not improve outcomes among women reporting risky alcohol use. Although not statistically significant, our results suggest that the intervention may also be more effective among women experiencing higher levels of poverty and HIV-related stigma. We observed no definitive mediator of the intervention effect, but women allocated to integrated services reported better relationships with their healthcare providers through 12 months postpartum. These findings point to high-risk groups that may benefit the most from integrated care, as well as groups for whom these benefits are hampered and that warrant further attention in intervention development and evaluation.

Projected Benefits of Long-Acting Antiretroviral Therapy in Nonsuppressed People With Human Immunodeficiency Virus Experiencing Adherence Barriers. Open Forum Infect Dis 2023; 10:ofad390. [PMID: 37601728 PMCID: PMC10439527 DOI: 10.1093/ofid/ofad390] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 07/19/2023] [Indexed: 08/22/2023] Open
Abstract
Background In a demonstration project, long-acting, injectable cabotegravir-rilpivirine (CAB-RPV) achieved viral suppression in a high proportion of people with HIV (PWH) who were virologically nonsuppressed with adherence barriers. We projected the long-term impact of CAB-RPV for nonsuppressed PWH experiencing adherence barriers. Methods Using the Cost-Effectiveness of Preventing AIDS Complications (CEPAC) model, we compared 3 strategies: (1) standard of care oral integrase inhibitor-based ART (INSTI); (2) INSTI-based ART with supportive social services ("wraparound services" [WS]) (INSTI/WS); and (3) CAB-RPV with WS (CAB-RPV/WS). Model outcomes included viral suppression (%) and engagement in care (%) at 3 years, and life expectancy (life-years [LYs]). Base case cohort characteristics included mean age of 47y (standard deviation [SD], 10y), 90% male at birth, and baseline mean CD4 count 150/µL (SD, 75/µL). Viral suppression at 3 months was 13% (INSTI), 28% (INSTI/WS), and 60% (CAB-RPV/WS). Mean loss to follow-up was 28/100 person-years (PY) (SD, 2/100 PY) without WS and 16/100 PY (SD, 1/100 PY) with WS. Results Projected viral suppression at 3 years would vary widely: 16% (INSTI), 38% (INSTI/WS), and 44% (CAB-RPV/WS). Life expectancy would be 7.4 LY (INSTI), 9.0 LY (INSTI/WS), and 9.4 LY (CAB-RPV/WS). Projected benefits over oral ART would be greater for PWH initiating CAB-RPV/WS at lower CD4 counts. Across plausible key parameter ranges, CAB-RPV/WS would improve viral suppression and life expectancy compared with oral INSTI strategies. Conclusions These model-based results support that long-acting injectable CAB-RPV with extensive support services for nonsuppressed PWH experiencing adherence barriers is likely to increase viral suppression and improve survival. A prospective study to provide further evidence is needed.

Rapid start antiretroviral therapies for improved engagement in HIV care: implementation science evaluation protocol. BMC Health Serv Res 2023; 23:503. [PMID: 37198586 DOI: 10.1186/s12913-023-09500-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 05/04/2023] [Indexed: 05/19/2023] Open
Abstract
BACKGROUND In 2020, the Health Resources and Services Administration's HIV/AIDS Bureau funded an initiative to promote implementation of rapid antiretroviral therapy initiation in 14 HIV treatment settings across the U.S. The goal of this initiative is to accelerate uptake of this evidence-based strategy and provide an implementation blueprint for other HIV care settings to reduce the time from HIV diagnosis to entry into care, for re-engagement in care for those out of care, initiation of treatment, and viral suppression. As part of the effort, an evaluation and technical assistance provider (ETAP) was funded to study implementation of the model in the 14 implementation sites. METHOD The ETAP has used implementation science methods framed by the Dynamic Capabilities Model integrated with the Conceptual Model of Implementation Research to develop a Hybrid Type II, multi-site mixed-methods evaluation, described in this paper. The results of the evaluation will describe strategies associated with uptake, implementation outcomes, and HIV-related health outcomes for patients. DISCUSSION This approach will allow us to understand in detail the processes that sites to implement and integrate rapid initiation of antiretroviral therapy as standard of care as a means of achieving equity in HIV care.

Low-level viraemia among people living with HIV in Nigeria: a retrospective longitudinal cohort study. Lancet Glob Health 2022; 10:e1815-e1824. [PMID: 36400087 PMCID: PMC9711923 DOI: 10.1016/s2214-109x(22)00413-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 08/31/2022] [Accepted: 09/15/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND HIV transmission can occur with a viral load of at least 200 copies per mL of blood and low-level viraemia can lead to virological failure; the threshold level at which risk for virological failure is conferred is uncertain. To better understand low-level viraemia prevalence and outcomes, we analysed retrospective longitudinal data from a large cohort of people living with HIV on antiretroviral therapy (ART) in Nigeria. METHODS In this retrospective cohort study using previously collected longitudinal patient data, we estimated rates of virological suppression (≤50 copies per mL), low-level viraemia (51-999 copies per mL), virological non-suppression (≥1000 copies per mL), and virological failure (≥2 consecutive virological non-suppression results) among people living with HIV aged 18 years and older who initiated and received at least 24 weeks of ART at 1005 facilities in 18 Nigerian states. We analysed risk for low-level viraemia, virological non-suppression, and virological failure using log-binomial regression and mixed-effects logistic regression. FINDINGS At first viral load for 402 668 patients during 2016-21, low-level viraemia was present in 64 480 (16·0%) individuals and virological non-suppression occurred in 46 051 (11·4%) individuals. Patients with low-level viraemia had increased risk of virological failure (adjusted relative risk 2·20, 95% CI 1·98-2·43; p<0·0001). Compared with patients with virological suppression, patients with low-level viraemia, even at 51-199 copies per mL, had increased odds of low-level viraemia and virological non-suppression at next viral load; patients on optimised ART (ie, integrase strand transfer inhibitors) had lower odds than those on non-integrase strand transfer inhibitors for the same low-level viraemia range (eg, viral load ≥1000 copies per mL following viral load 400-999 copies per mL, integrase strand transfer inhibitor: odds ratio 1·96, 95% CI 1·79-2·13; p<0·0001; non-integrase strand transfer inhibitor: 3·21, 2·90-3·55; p<0·0001). INTERPRETATION Patients with low-level viraemia had increased risk of virological non-suppression and failure. Programmes should revise monitoring benchmarks and targets from less than 1000 copies per mL to less than 50 copies per mL to strengthen clinical outcomes and track progress to epidemic control. FUNDING None.

Abstract
Importance A patient's belief in the likely success of a treatment may influence outcomes, but this has been understudied in surgical trials. Objective To examine the association between patients' baseline beliefs about the likelihood of treatment success with outcomes of antibiotics for appendicitis in the Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial. Design, Setting, and Participants This was a secondary analysis of the CODA randomized clinical trial. Participants from 25 US medical centers were enrolled between May 3, 2016, and February 5, 2020. Included in the analysis were participants with appendicitis who were randomly assigned to receive antibiotics in the CODA trial. After informed consent but before randomization, participants who were assigned to receive antibiotics responded to a baseline survey including a question about how successful they believed antibiotics could be in treating their appendicitis. Interventions Participants were categorized based on baseline survey responses into 1 of 3 belief groups: unsuccessful/unsure, intermediate, and completely successful. Main Outcomes and Measures Three outcomes were assigned at 30 days: (1) appendectomy, (2) high decisional regret or dissatisfaction with treatment, and (3) persistent signs and symptoms (abdominal pain, tenderness, fever, or chills). Outcomes were compared across groups using adjusted risk differences (aRDs), with propensity score adjustment for sociodemographic and clinical factors. Results Of the 776 study participants who were assigned antibiotic treatment in CODA, a total of 425 (mean [SD] age, 38.5 [13.6] years; 277 male [65%]) completed the baseline belief survey before knowing their treatment assignment. Baseline beliefs were as follows: 22% of participants (92 of 415) had an unsuccessful/unsure response, 51% (212 of 415) had an intermediate response, and 27% (111 of 415) had a completely successful response. Compared with the unsuccessful/unsure group, those who believed antibiotics could be completely successful had a 13-percentage point lower risk of appendectomy (aRD, -13.49; 95% CI, -24.57 to -2.40). The aRD between those with intermediate vs unsuccessful/unsure beliefs was -5.68 (95% CI, -16.57 to 5.20). Compared with the unsuccessful/unsure group, those with intermediate beliefs had a lower risk of persistent signs and symptoms (aRD, -15.72; 95% CI, -29.71 to -1.72), with directionally similar results for the completely successful group (aRD, -15.14; 95% CI, -30.56 to 0.28). Conclusions and Relevance Positive patient beliefs about the likely success of antibiotics for appendicitis were associated with a lower risk of appendectomy and with resolution of signs and symptoms by 30 days. Pathways relating beliefs to outcomes and the potential modifiability of beliefs to improve outcomes merit further investigation. Trial Registration ClinicalTrials.gov Identifier: NCT02800785.

Abstract
This study tested the hypothesis that the co-occurrence of alcohol use and depressive symptoms predicts HIV suppression and antiretroviral therapy (ART) adherence among people living with HIV. Baseline cross-sectional results showed a significant interaction between depressive symptoms and alcohol use in predicting HIV suppression; individuals who drank more alcohol and had higher depressive symptoms demonstrated poorer HIV suppression relative to those who had fewer depressive symptoms. In a one-year longitudinal analysis of ART adherence, alcohol use and depressive symptoms measured in daily text-message assessments demonstrated that neither alcohol use nor depressive symptoms alone predicted ART adherence. However, the intersection of alcohol use on days when experiencing depressive symptoms did significantly predict ART non-adherence, for both moderate and heavy alcohol drinkers. Findings suggest that the co-occurrence of alcohol use and depressive symptoms is a robust predictor of poor HIV treatment outcomes.

The Associations among Gender, Age, eHealth Literacy, Beliefs about Medicines and Medication Adherence among Elementary and Secondary School Teachers. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19116926. [PMID: 35682509 PMCID: PMC9180475 DOI: 10.3390/ijerph19116926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/21/2022] [Accepted: 06/03/2022] [Indexed: 02/04/2023]
Abstract
Background: A lack of health literacy may negatively impact patient adherence behavior in health care delivery, leading to a major threat to individual health and wellbeing and an increasing financial burden on national healthcare systems. Therefore, how to cultivate citizens’ health literacy, especially electronic health (eHealth) literacy that is closely related to the Internet, may be seen as a way to reduce the financial burden of the national healthcare systems, which is the responsibility of every citizen. However, previous studies on medication adherence have mostly been conducted with chronic disease patient samples rather than normal samples. Teachers are not only the main body of school health efforts, but also role models for students’ healthy behavior. Therefore, understanding differences in eHealth literacy beliefs among schoolteachers would be helpful for improving the existing health promoting programs and merit specific research. Aims: The present study identified the relationships among gender, age, electronic health (eHealth) literacy, beliefs about medicines, and medication adherence among elementary and secondary school teachers. Methods: A total of 485 teachers aged 22−51 years completed a pen-and-paper questionnaire. The instruments included an eHealth literacy scale, a belief about medicines scale and a medication adherence scale. Results: The results showed a significant difference between genders in necessity beliefs about medication (t = 2.00, p < 0.05), and a significant difference between ages in functional eHealth literacy (F = 3.18, p < 0.05) and in necessity beliefs about medication (Welch = 7.63, p < 0.01). Moreover, age (β = 0.09), functional eHealth literacy (β = 0.12), and necessity beliefs about medication (β = 0.11) positively predicted medication adherence, while concerns about medication (β = −0.23) negatively predicted medication adherence. Conclusions: The results showed that male teachers had stronger concerns about medication than female teachers. Teachers aged 42−51 years had lower functional eHealth literacy and stronger necessity beliefs about medication than teachers aged 22−31 years. In addition, teachers who were older, had higher functional eHealth literacy, had stronger necessity beliefs about medication, and had fewer concerns about medication tended to take their medications as prescribed. These findings revealed that helping teachers develop high eHealth literacy and positive beliefs about medicines is an effective strategy for improving medication adherence.

Perspectives on preparing for long-acting injectable treatment for HIV among consumer, clinical and nonclinical stakeholders: A qualitative study exploring the anticipated challenges and opportunities for implementation in Los Angeles County. PLoS One 2022; 17:e0262926. [PMID: 35113892 PMCID: PMC8812879 DOI: 10.1371/journal.pone.0262926] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Accepted: 01/09/2022] [Indexed: 01/01/2023] Open
Abstract
Long-acting injectable (LAI) antiretroviral therapy (ART) is a novel HIV treatment option for people with HIV. The first LAI ART regimen for HIV treatment received regulatory approval in the United States in January 2021. In February 2020, we collected qualitative data from 18 consumers and 23 clinical and non-clinical stakeholders to catalog anticipated individual-consumer, healthcare system, and structural levels barriers and facilitators to LAI ART implementation in Los Angeles County, California. Thematic analysis was guided by the CFIR implementation science model. CFIR constructs of intervention characteristics, individual characteristics, outer and inner setting, intervention characteristics, and implementation process emerged in analysis. Under intervention characteristics, anticipated facilitators included the relative advantage of LAI ART over pills for adherence and reduced treatment management burden and related anxiety; anticipated barriers included non-adherence to injection appointments, concerns of developing HIV resistance, discomfort with injection and cost. Anticipated facilitators based on individual characteristics included overall acceptability based on knowledge and positive beliefs about LAI ART. Participant noted several characteristics of the outer setting that could negatively impact implementation, such as medical mistrust, external policies, and LAI ART eligibility (i.e., to be virally suppressed prior to initiation). Participants were optimistic about the potential to decrease stigma but expressed that provider willingness for adoption could be hindered by challenges in organizational inner setting related to payment authorizations, increased staffing needs, medication procurement and storage, and provider and healthcare system readiness. Results from this pre-implementation study may inform rollout and scale-up of LAI ART in Los Angeles County.

Abstract
BACKGROUND The daily oral dosing requirement for antiretroviral therapy (ART) may be challenging for some people living with HIV (PLWHIV) with comorbid conditions, confidentiality concerns or pill fatigue. We investigated suboptimal adherence from the perspective of PLWHIV and HIV physicians. METHODS PLWHIV on ART (n = 688) and HIV physicians (n = 120) were surveyed during 2019 in France, Germany, Italy and the UK. Suboptimal adherence was a report the participant missed taking their dose as prescribed 'Sometimes'/'Often'/'Very often'. Physicians' interest in offering a hypothetical long-acting HIV regimen for suboptimally adherent patients was assessed. Descriptive and multivariable analyses were performed (P < 0.05). RESULTS Of PLWHIV, 23.8% (164/688) reported suboptimal adherence vs. providers' estimated prevalence of 33.6% (SD = 28.8). PLWHIV-reported prevalence of specific suboptimal adherence behaviors were: mistimed dose [16.1% (111/688)]; missed a dose [15.7% (108/688)]; dosed under wrong conditions [e.g. food restrictions, 10.5% (72/688)] and overdosed [3.3% (23/688)]. Odds of suboptimal adherence were higher among those with vs. without a report of the following: dysphagia (AOR = 3.61, 95% CI = 2.28-5.74), stress/anxiety because of their daily dosing schedule (AOR = 3.09, 95% CI = 1.97-4.85), gastrointestinal side effects (AOR = 2.09, 95% CI = 1.39-3.15), neurocognitive/mental health conditions (AOR = 1.88, 95% CI = 1.30-2.72) or hiding their HIV medication (AOR = 1.51, 95% CI = 1.04-2.19). Of providers, 84.2% indicated they Definitely/Probably will offer a hypothetical long-acting HIV regimen 'for patients who have suboptimal levels of adherence to daily oral therapy (50-90%) for non-medical reasons'. CONCLUSIONS Dysphagia, stressful daily oral dosing schedule, gastrointestinal side effects, neurocognitive/mental health conditions and confidentiality concerns were associated with suboptimal adherence in our study. Adherence support and alternative regimens, such as long-acting antiretroviral therapies, could help address these challenges.

Evaluation of the Sociodemographic, Behavioral and Clinical Influences on Complete Antiretroviral Therapy Adherence Among HIV-Infected Adults Receiving Medical Care in Houston, Texas. HIV AIDS-RESEARCH AND PALLIATIVE CARE 2021; 13:539-555. [PMID: 34040451 PMCID: PMC8140896 DOI: 10.2147/hiv.s303791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Accepted: 04/10/2021] [Indexed: 11/28/2022]
Abstract
Introduction Few studies have estimated complete antiretroviral therapy (ART) adherence following HIV infection since the advent of the new ART guidelines in 2012. This study determined the prevalence and influence of sociodemographic, behavioral, and clinical factors on complete ART adherence among people living with HIV (PLWH) receiving medical care in Houston/Harris County, Texas. Methods Data from the Houston Medical Monitoring Project survey collected from 2009 to 2014 among 1073 participants were used in this study. The primary outcome evaluated was combined adherence, defined as complete, partial, and incomplete combined adherence based on three ART adherence types—dose, schedule, and instruction adherence. The duration living since initial HIV diagnosis was classified as <5, 5–10 and >10 years. Rao–Scott Chi-square test and multivariable proportional-odds cumulative logit regression models were employed to identify the sociodemographic, behavioral, and clinical characteristics of complete combined adherence among the three groups of PLWH living with HIV infection. Results More than one-half (54.4%) of PLWH had complete, 37.4% had partial, and 8.3% had incomplete combined adherence. Among these PLWH, 52.2% had been infected with HIV for >10 years, and 26.5% and 21.4% were infected for <5 years and 5–10 years, respectively. PLWH who were diagnosed <5 and 5–10 years were two times (aOR=1.71, 95% CI=1.13–2.57; aOR=1.69, 95% CI=1.10–2.59; respectively) more likely to experience complete combined adherence than those with >10 years of infection. Multiple sociodemographic, behavioral, and clinical characteristics were significantly associated with complete adherence and varied by the duration of HIV infection. Conclusion Measures of adherence should include all adherence types (dose, schedule, instruction), as utilizing a single adherence type will overestimate adherence level in PLWH receiving medical care. Intervention efforts to maintain adherence should target recently infected PLWH, while those aimed at improving adherence should focus on longer infected PLWH.

Abstract
BACKGROUND Prescribing oral oncolytic agents (OAs) for advanced cancers is increasing. AIMS To explore changes in medication beliefs and the effects of symptom severity, cognitive effectiveness and depressive symptoms on medication beliefs over 12 weeks. METHODS Secondary analysis of a randomized controlled trial, testing an intervention to promote symptom management and adherence [N = 230]. Questionnaires evaluated medication beliefs, symptom severity, depressive symptoms, and cognitive effectiveness. Linear mixed effects models were used for analyses. RESULTS OA Necessity beliefs increased over time (mean difference 0.0112, SE = 0.055, p 0.04). Concern beliefs did not change and were lower for advanced cancers (-0.193, SE = 0.067, p < 0.01).Depressive symptoms were related to decreased Necessity beliefs (-0.012, SE = 0.005, p = 0.02), but not Concern beliefs. Medication beliefs were not associated with symptom severity or cognitive effectiveness. CONCLUSION Patients with advanced cancer hold different medication beliefs compared to earlier staged cancers, lending insight into potential outcomes beyond adherence.

Abstract
BACKGROUND Comorbidity rates and service needs are high among people living with HIV/AIDS (PLWHA). The effects of service utilization and unmet service needs on antiretroviral therapy (ART) adherence are not well understood. The purpose of this study was to investigate associations among PLWHA's service utilization, unmet service needs, and ART adherence. METHODS PLWHA (N=162) 18 years or older were recruited from a Nevada statewide needs assessment project in 2016. Participants completed a self-administered questionnaire on paper or online. The independent variables were service utilization and unmet service needs. The outcome variable was ART adherence. Multivariable logistic regression analyses were conducted to examine associations between the amount of utilized services and unmet service needs with ART adherence. RESULTS Only 12 (7.5%) participants reported they received all the needed services. The ART nonadherence group showed significantly higher unmet medical service needs compared to the ART adherence group (p=0.007). Unmet medical service needs (Adjusted Odds Ratio (AOR) 0.69, CI 0.53-0.90) and unmet support service needs (AOR 0.68, CI 0.48-0.97) were negatively associated with ART adherence. However, utilizing medical services (AOR 1.06, CI 0.87-1.30) and support services (AOR 0.88, CI 0.74-1.04) in the current year were not significantly associated with ART adherence. CONCLUSION The results of this study indicate that health promotion programming should focus not only on introducing new services at the community level, but also work to optimize the availability and awareness of current services. Furthermore, health promotion programs should focus on filling service coverage gaps and improving the facilitation of services.

Abstract
BACKGROUND Maintaining adherence to antiretroviral therapy (ART) is a significant challenge for human immunodeficiency virus (HIV)-infected racial and ethnic minority adolescents and young adults (youth). Given the consequences of suboptimal ART adherence, there is a pressing need for an expanded understanding of adherence behavior in this cohort. OBJECTIVES As part of an exploratory sequential, mixed-methods study, we used qualitative inquiry to explore adherence information, motivation, and behavioral skills among HIV-infected racial and ethnic minority youth. Our secondary aim was to gain an understanding of the contextual factors surrounding adherence behavior. METHODS The information-motivation-behavioral skills model (IMB model) was applied to identify the conceptual determinants of adherence behavior in our target population, along with attention to emergent themes. In-depth, individual, semistructured interviews, including open-ended questions with probes, were conducted with a convenience sample of HIV-infected racial and ethnic minority youth (ages 16-29 years), receiving ART and with evidence of virologic failure (i.e., detectable HIV viral load). New participants were interviewed until information redundancy was reached. Qualitative interviews were digitally recorded, transcribed verbatim, and analyzed using Atlas.ti (v8). Directed content analysis was performed to generate categories and broad themes. Coding was initially conceptually driven (IMB model) and shifted to a data-driven approach, allowing for the discovery of key contextual factors that influence adherence behavior in this population. Methodological rigor was ensured by member checks, an audit trail, thick descriptive data, and triangulation of data sources. RESULTS Twenty racial and ethnic minority participants (mean age = 24.3 years, 55.0% male) completed interviews. We found adherence information was understood in relation to HIV biomarkers; adherence motivation and behavioral skills were influenced by stigma and social context. We identified five primary themes regarding ART self-management: (a) emerging adulthood with a chronic illness, (b) stigma and disclosure concerns, (c) support systems and support deficits, (d) mental and behavioral health risks and challenges, and (e) mode of HIV transmission and perceptions of power and control. DISCUSSION Key constructs of the IMB model were applicable to participating HIV-infected youth yet did not fully explain the essence of adherence behavior. As such, we recommend expansion of current adherence models and frameworks to include known contextual factors associated with ART self-management among HIV-infected racial and ethnic minority youth.

Health Care-Specific Enacted HIV-Related Stigma's Association with Antiretroviral Therapy Adherence and Viral Suppression Among People Living with HIV in Florida. AIDS Patient Care STDS 2020; 34:316-326.

Abstract
Among people living with HIV (PLWH) in Florida, <2/3 are virally suppressed (viral load <200 copies/mL). Previous theoretical frameworks have pointed to HIV-related stigma as an important factor for viral suppression; an important outcome related to the HIV continuum of care. This study aims to analyze the association between enacted HIV-related stigma and antiretroviral therapy (ART) adherence and viral suppression among a sample of PLWH in Florida. The overall sample (n = 932) was male (66.0%), majority greater than 45 years of age (63.5%), black (58.1%), and non-Hispanic (79.7%). Adjusted odds ratios (AOR) and 95% confidence intervals (CI) were estimated using logistic regression models. The odds of nonadherence to ART was not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 1.30, CI: (0.87-1.95), p = 0.198; AOR = 1.17, CI: (0.65-2.11), p = 0.600, respectively]. Moreover, the odds of nonviral suppression were not significantly greater for those reporting low/moderate or high levels of general enacted HIV-related stigma (vs. no stigma) [AOR = 0.92, CI: (0.60-1.42), p = 0.702; AOR = 1.16, CI: (0.64-2.13), p = 0.622, respectively]. However, ever experiencing health care-specific enacted HIV-related stigma was associated with both nonadherence [AOR = 2.29, CI: (1.25-4.20), p = 0.008] and nonsuppression [AOR = 2.16, CI: (1.19-3.92), p = 0.011]. Despite limitations, the results suggest that the perpetuation of stigma by health care workers may have a larger impact on continuum of care outcomes of PLWH than other sources of enacted stigma. Based on the results, there is a need to develop and evaluate interventions for health care workers intended to reduce experienced stigma among PLWH and improve health outcomes.

Abstract
Beliefs that it is harmful to mix medications with alcohol (ie, interactive toxicity beliefs) are a known source of intentional antiretroviral therapy (ART) nonadherence. This study examined a serial process model of alcohol-ART interactive toxicity beliefs, alcohol-ART avoidance behaviors, and ART adherence in the association between alcohol use and HIV viral load. Participants were 198 patients receiving ART from a community clinic in the southeastern United States; 125 reported current alcohol use. Results showed that current alcohol use was associated with detectable HIV viral load, partially accounted for by alcohol-ART interactive toxicity beliefs, alcohol-ART avoidance behaviors, and ART adherence. There was a significant indirect effect of the serial chain of interactive toxicity beliefs-avoidance behaviors-adherence, indicating the 3 intermediating variables partially accounted for the relationship between alcohol use and HIV viral load. Addressing alcohol use as a barrier to ART adherence requires multipronged approaches that address intentional nonadherence.

Abstract
OBJECTIVES New international guidelines for antenatal care (ANC) will likely result in an increase in nutritional supplements and preventative medications for pregnant women in low and middle-income countries. Our objective was to understand how pregnant women in Mali perceive and experience multi-drug regimens in ANC in order to reveal factors that may influence uptake and adherence. METHODS We conducted 29 semi-structured interviews and three focus groups with 21 pregnant women in two urban ANC sites in Bamako, Mali. Interviews focused on perception of purpose of ANC pharmaceuticals (particularly iron supplements, sulfadoxine-pyrimethamine as intermittent prevention of malaria and antiretroviral therapy for HIV), beliefs regarding efficacy and risk, and understanding of dosage and regimen. Transcripts were inductively coded and analyzed using the 'Framework' method. RESULTS Participant descriptions of medication purpose, understanding of dosing, and beliefs about risks and efficacy varied widely, revealing that many pregnant women lack complete information about their medications. While some were burdened by side effects or complex regimens, women generally held favorable attitudes toward ANC medications. Responses suggest major barriers to adherence lie in the health system, namely insufficient patient-provider communication and inconsistent prescribing practices. CONCLUSIONS FOR PRACTICE National health programs looking to improve maternal and child health with ANC pharmaceuticals need to place greater attention on patient counseling and consistent implementation of administration guidelines. Communication that positions pharmaceuticals as beneficial to mother and child, while presenting understandable information about purpose, dosing and potential side effects can promote uptake of multi-drug regimens and ANC services in general.

Abstract
Although anticipated HIV-related stigma-the expectation that one will experience prejudice and discrimination in the future as a result of others learning his or her HIV positive status-is theorized to be a robust predictor of antiretroviral therapy (ART) non-adherence, the association between anticipated stigma and ART non-adherence has been inconsistent. It may be, however, that anticipated stigma reliably, but indirectly, contributes to poor ART adherence through other psychosocial mechanisms. In the current study, we examine whether anticipated stigma indirectly contributes to treatment non-adherence through increased medication concerns. In a cross-sectional study, 585 people living with HIV in Atlanta and Macon, Georgia completed measures of anticipated HIV-related stigma, HIV-medication concerns, and HIV-treatment adherence. A latent variable mediation analysis revealed that anticipated stigma was positively associated with increased medication concerns, which consequently contributed to treatment non-adherence. Results reveal a psychosocial mechanism by which anticipated stigma contributes to ART non-adherence.

Abstract
Consistent antiretroviral adherence is key to viral suppression, but many low-income people of color living with HIV are not optimally adherent due to a wide variety of interrelated social and structural factors. Previous studies have found that HIV medication beliefs are an important facet of adherence. In contrast to the AZT era , currently available antiretroviral therapies are significantly safer and more effective, but research suggests that negative beliefs may persist among racial and ethnic minority people. Twenty-seven semi-structured interviews were conducted with low-income Black and Latinx people living with HIV in New York City that were currently, or had been recently, disengaged from outpatient HIV medical care. This research suggests that socially and economically marginalized people living with HIV, many long-term survivors who lived through the AZT era, recognized that current treatments are very effective in making HIV a chronic, manageable illness and a significant improvement compared to the therapies early in the epidemic. Most importantly, the data suggests that people demonstrate great resilience despite their experiences of social and economic exclusion. Both clinical practice and public health interventions can benefit from these findings. HIV care providers should speak with patients about their beliefs related to HIV medication, and public health interventions should specifically address HIV medication-related beliefs in order to enhance adherence. In order to avoid reifying people's marginalization, public health should endeavor to recognize and support people's resilience.

Abstract
Objectives. To use statewide surveillance data to examine trends and disparities in mortality and progression from HIV to AIDS comprehensively in Tennessee over the past 20 years.Methods. Individuals diagnosed with HIV in Tennessee from 1996 to 2016 were identified through the Tennessee Department of Health Enhanced HIV/AIDS Reporting System. Clinical AIDS and all-cause mortality were the outcomes. Cox regression yielded adjusted hazard ratios (AHRs) for death and competing risk regression yielded adjusted subhazard ratios (SHRs) for AIDS, with death as the competing event.Results. Individuals with a history of heterosexual contact (AHR = 1.20; 95% confidence interval [CI] = 1.12, 1.29) and injection drug use (AHR = 1.27; 95% CI = 1.18, 1.38) had increased hazards of death relative to those with a history of male-to-male sexual contact. Hazards of death were lower among White (AHR = 0.79; 95% CI = 0.73, 0.85) and Hispanic (AHR = 0.50; 95% CI = 0.40, 0.63) individuals than among Black individuals. Those with heterosexual contact (SHR = 1.20; 95% CI = 1.12, 1.29) and injection drug use (SHR = 1.27; 95% CI = 1.18, 1.38) had a greater risk of AIDS than those with male-to-male sexual contact. White individuals (SHR = 0.85; 95% CI = 0.81, 0.90) had a lower risk of AIDS than Black individuals, and female individuals (SHR = 0.84; 95% CI = 0.79, 0.90) had a lower risk than male individuals.Conclusions. The trends, disparities, and outcomes assessed in our study will inform HIV testing and care linkage program design and implementation in Tennessee.

Abstract
Adherence to antiretroviral therapy (ART) during pregnancy and the postpartum period is necessary to prevent vertical HIV transmission and to secure the long-term health of an HIV-infected woman. Health behavior theory suggests that patients' attitudes towards medication can predict their medication-taking behaviour. This study sought to understand how women's attitudes towards ART changes between the pregnancy and postpartum periods, and the factors associated with these attitudes. The study enrolled 200 pregnant women living with HIV. Structured surveys were administered during pregnancy and at three and 6 months postpartum. Overall, attitudes towards ART were stable over time. More positive attitudes towards ART were associated with HIV acceptance, lower levels of depression, and lower levels of shame. Counselling interventions are needed to help HIV-infected women accept their status and reduce shameful emotions. Depression screening and treatment should be integrated into PMTCT services. This study emphasizes the importance of early attention to attitudes towards ART, in order to establish a trajectory of sustained care engagement.

Abstract
To inform the development of interventions to increase uptake and adherence to antiretroviral therapy (ART), we explored perceptions of ART in semi-structured interviews with 52 men and women from UK black African and black Caribbean communities. Verbatim transcripts were analyzed using framework analysis. Perceptions of ART could be grouped into two categories: doubts about the personal necessity for ART and concerns about potential adverse effects. Doubts about necessity stemmed from feeling well, doubts about the efficacy of ART, religious beliefs and the belief that treatment was futile because it could not cure HIV. Concerns about adverse effects included the fear that attending HIV services and taking treatment would lead to disclosure of HIV, feeling overwhelmed at the prospect of starting treatment soon after diagnosis, fears about side effects and potential long-term effects, and physical repulsion. The findings will facilitate the development of interventions to increase uptake and adherence to ART.

Abstract
According to the Necessity-Concerns Framework, beliefs about medication necessity and concerns are two core themes from diverse patient medication beliefs across chronic illnesses that may directly influence adherence. Past work has supported associations of necessity and concerns to adherence in the chronic disease literature and in HIV research. However, there has not been a focused review of the literature on associations of necessity and concerns to HIV medication adherence, nor on what variables may influence these associations. This systematic review synthesized findings from 26 studies regarding associations of necessity and concerns to HIV medication adherence. Both beliefs showed small, clinically significant effects on adherence. A subset of studies identified perceptions of healthcare providers as determinants of necessity and concerns beliefs with indirect effects on adherence. Overall, necessity and concerns demonstrated clinically significant associations to adherence among people with HIV.

Abstract
Background The highest rates of new HIV infections are observed in African Americans and Hispanics/Latinos (ethnic minority) adolescents and young adults (youth). HIV-infected ethnic minority youth are less likely to initiate and maintain adherence to antiretroviral treatment (ART) and medical care, as compared with their adult counterparts. Objective The objective of this research protocol was to describe our proposed methods for testing a peer-led mobile health cognitive behavioral intervention, delivered via remote videoconferencing and smartphones with HIV-infected ethnic minority youth, Adherence Connection for Counseling, Education, and Support (ACCESS). Our secondary aim was to obtain initial estimates of the biobehavioral impact of ACCESS on HIV virologic outcomes and self-reported ART adherence, beliefs and knowledge about ART treatment, adherence self-efficacy, and health care utilization (retention in care). Methods An exploratory, sequential mixed-methods study design will be used with conceptual determinants of adherence behavior informed by the information-motivation-behavioral skills model. HIV-infected ethnic minority youth aged 16 to 29 years with a detectable HIV serum viral load of more than 200 copies/ml (N=25) will be recruited. Qualitative pretesting will be conducted, including semistructured, in-depth, individual interviews with a convenience sample meeting the study inclusion criteria. Preliminary analysis of qualitative data will be used to inform and tailor the ACCESS intervention. Testing and implementation will include a one-group pre-posttest pilot, delivered by a trained successful peer health coach who lives with HIV and is well-engaged in HIV care and taking ART. A total of 5 peer-led remote videoconferencing sessions will be delivered using study-funded smartphones and targeting adherence information (HIV knowledge), motivation (beliefs and perceptions), and behavioral skills (self-efficacy). Participant satisfaction will be assessed with poststudy focus groups and quantitative survey methodology. Bivariate analyses will be computed to compare pre- and postintervention changes in HIV biomarkers, self-reported ART adherence, beliefs and knowledge about ART, adherence self-efficacy, and retention in care. Results As of December 2018, we are in the data analysis phase of this pilot and anticipate completion with dissemination of final study findings by spring/summer 2019. The major outcomes will include intervention feasibility, acceptability, and preliminary evidence of impact on serum HIV RNA quantitative viral load (primary adherence outcome variable). Self-reported ART adherence and retention in care will be assessed as secondary outcomes. Findings from the qualitative pretesting will contribute to an improved understanding of adherence behavior. Conclusions Should the ACCESS intervention prove feasible and acceptable, this research protocol will contribute to a shift in existent HIV research paradigms by offering a blueprint for technology-enabled peer-led interventions and models.

Abstract
OBJECTIVE This paper describes a derived model that provides a conceptual framework for understanding medication beliefs among patients with advanced cancer receiving oral oncolytic agents. METHODS Theory derivation was used to (a) examine the phenomenon of medication beliefs in cross-disciplinary research; (b) select a parent theory for derivation; (c) identify parent theory concepts and/or structure to use in derivation; and (d) redefine parent theory concepts and structure to create a derived model. RESULTS Medication beliefs are shaped by previous experiences, including cognitive and emotional factors, past health and illness encounters, and medication-taking behaviours. Medication beliefs are defined within a larger mental model of illness representation for which medication was prescribed. Individuals independently hold both positive and negative medication beliefs at the same time. This distinction is critical to understanding how dichotomous components of medication beliefs change over time as they are influenced by varying treatment-related factors. CONCLUSION This paper contributes to conceptual knowledge regarding the phenomenon of medication beliefs and their impact on health behaviour. Findings can support oncology interventions to improve patient outcomes including medication adherence.

Abstract
The Southern United States has been disproportionately affected by HIV diagnoses and mortality. To inform efforts to effectively address HIV in the South, this manuscript synthesizes recent data on HIV epidemiology, care financing, and current research literature on factors that predispose this region to experience a greater impact of HIV. The manuscript focuses on a specific Southern region, the Deep South, which has been particularly affected by HIV. Epidemiologic data from the Centers from Disease Control and Prevention indicate that the Deep South had the highest HIV diagnosis rate and the highest number of individuals diagnosed with HIV (18,087) in 2014. The percentage of new HIV diagnoses that were female has decreased over time (2008-2014) while increasing among minority MSM. The Deep South also had the highest death rates with HIV as an underlying cause of any US region in 2014. Despite higher diagnosis and death rates, the Deep South received less federal government and private foundation funding per person living with HIV than the US overall. Factors that have been identified as contributors to the disproportionate effects of HIV in the Deep South include pervasive HIV-related stigma, poverty, higher levels of sexually transmitted infections, racial inequality and bias, and laws that further HIV-related stigma and fear. Interventions that address and abate the contributors to the spread of HIV disease and the poorer HIV-related outcomes in the Deep South are warranted. Funding inequalities by region must also be examined and addressed to reduce the regional disparities in HIV incidence and mortality.

Abstract
Across sub-Saharan Africa, prevention of mother-to-child transmission services are encountering increasing numbers of women already established on antiretroviral therapy (ART) when entering antenatal care. However, there are few data examining ART adherence and HIV viral load in this group. We used multivariable logistic regression models to examine self-reported suboptimal adherence (defined as missed ART doses on ≥2 days during the preceding 30 days), elevated viral load (≥1000 copies/mL), and factors associated with each among women entering antenatal care on ART. Participants were recruited from one primary care clinic in Gugulethu, Cape Town, as part of a larger study of HIV-positive pregnant and postpartum women. Among 482 pregnant women established on ART and enrolled between May 2013 and June 2014 (median age: 31 years; median duration of ART use: 3 years), 15% reported suboptimal adherence and 12% had elevated viral load. After adjustment for age, suboptimal adherence was significantly more common among women who were not married/cohabiting and women who reported a higher level of concern about taking ART; a higher level of adherence self-efficacy was associated with a reduced odds of suboptimal adherence. In a multivariable model, elevated viral load was significantly associated with previous discontinuation of ART, a higher level of concern about taking ART, and report of an unintended pregnancy. Suboptimal adherence and elevated viral load are common among women entering antenatal care already on ART. Our findings highlight specific beliefs and concerns about ART use during pregnancy that should be addressed in counselling messaging, and suggest that family planning should be more effectively integrated into HIV care. Including adherence and viral load monitoring as part of pregnancy planning for women on ART may be important to achieve safer conception and promote healthy pregnancies.

Abstract
This study applying the health services utilization model examined the importance of predisposing, enabling, and need variables to the social mechanisms explaining lifetime HIV testing across racial/ethnic groups. Data for the study were derived from the National Health Interview Survey (collected 2013–2014), our final sample numbering 18,574 adults. Four subsamples reflected race/ethnicity: 13,347 Whites, 2267 Blacks, 2074 Hispanics, and 886 Asians. Logistic regression established respondent odds of ever having received HIV testing. Further statistical testing evaluated race/ethnicity’s potential moderating role in HIV testing. The findings generally support a role for Aday’s predisposing, enabling, and need factors in explaining HIV testing. Across the four subsamples, female gender, older age, and sexual minority status consistently increased lifetime HIV testing. However, we found racial/ethnic differences in HIV testing’s associations with these factors and others. Our study made a beginning in the effort to specify mechanisms leading to HIV testing—and reliable diagnosis—among four racial/ethnic groups. Understanding these mechanisms might multiply opportunities to raise testing rates for all, in turn reducing racial/ethnic disparities in HIV treatment.

Abstract
Background Stigmatization due to HIV status may interfere with disease management among persons living with HIV (PLWHA) by heightening serostatus disclosure concerns and vulnerability to depressive symptoms. Purpose In this cross-sectional study, indirect effects of disclosure concerns and depressive symptoms were examined for the association of stigma to treatment adherence (medication and clinic appointment adherence) in an outpatient sample of PLWHA. Method Participants (N = 179; 47% White, 41% African-American; 35% MSM) completed measures of stigma-related experiences, concerns about disclosing HIV status, depression, and medication adherence; clinic appointment attendance was obtained from chart data. Results Stigma had an indirect effect on medication adherence (but not clinic attendance) via disclosure concerns. Stigma had indirect effects on both medication adherence and clinic attendance via depressive symptoms. In path analyses including both disclosure concerns and depressive symptoms, combined indirect effects emerged for both medication adherence and clinic attendance. There was a significant indirect pathway from stigma to disclosure concerns to depression to clinic attendance, whereas the positioning of the mediators was swapped for the significant indirect pathway from stigma to medication adherence. Conclusions These analyses provide evidence that stigmatizing experiences negatively affect treatment adherence through the indirect effects of disclosure concerns and depressive symptoms. Disclosure concerns and depressive symptoms are two mechanisms worthy of further research to enhance understanding of the association between stigma and treatment adherence difficulties.

Abstract
BACKGROUND Previous research has produced inconsistent evidence of an association between housing stability and medication adherence among HIV-positive individuals in antiretroviral therapy. OBJECTIVE We conducted a meta-analysis of the housing-adherence relationship based on a comprehensive search of observational studies in the PubMed, Embase, and Cochrane databases (January 2000-January 2016). Ten qualifying studies were identified representing 10,556 individuals. METHODS A random-effects model was used to estimate the overall effect size and 95% confidence interval (CI). Robustness of the estimate was determined by sensitivity analysis. Heterogeneity was assessed by meta-regression analysis, subgroup analysis, and quality effects estimation. Publication bias was evaluated with a funnel plot and the Egger and Begg tests. RESULTS The summary effect for the association between housing stability and medication adherence was positive and significant (standardized mean difference = 0.15, 95% CI: 0.02 to 0.29). The association was slightly larger in the quality effects analysis (standardized mean difference = 0.20, 95% CI: 0.01 to 0.39). Sensitivity analysis disclosed that the association was robust at the P = 0.09 level. Results of the subgroup and meta-regression analyses were nonsignificant. Publication bias was not detected. CONCLUSION Antiretroviral medication adherence is an increasing function of housing stability, but the magnitude of the effect is small. The finding challenges the view that unstable housing is incompatible with adherence and questions the potential benefit of deferring antiretroviral therapy initiation until the patient's housing circumstances are improved.
