Abstract
OBJECTIVES Determine whether patient-centered, streamlined HIV care achieves higher antiretroviral therapy (ART) uptake and viral suppression than the standard treatment model for people with HIV (PWH) reporting hazardous alcohol use. DESIGN Community cluster-randomized trial. METHODS The Sustainable East Africa Research in Community Health trial (NCT01864603) compared an intervention of annual population HIV testing, universal ART, and patient-centered care with a control of baseline population testing with ART by country standard in 32 Kenyan and Ugandan communities. Adults (15 years or older) completed a baseline Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) and were classified as no/nonhazardous (AUDIT-C 0-2 women/0-3 men) or hazardous alcohol use (≥3 women/≥4 men). We compared year 3 ART uptake and viral suppression of PWH reporting hazardous use between intervention and control arms. We compared alcohol use as a predictor of year 3 ART uptake and viral suppression among PWH, by arm. RESULTS Of 11,070 PWH with AUDIT-C measured, 1723 (16%) reported any alcohol use and 893 (8%) reported hazardous use. Among PWH reporting hazardous use, the intervention arm had higher ART uptake (96%) and suppression (87%) compared with control (74%, adjusted risk ratio [aRR] = 1.28, 95% CI: 1.19 to 1.38; and 72%, aRR = 1.20, 95% CI: 1.10 to 1.31, respectively). Within arm, hazardous alcohol use predicted lower ART uptake in control (aRR = 0.86, 95% CI: 0.78 to 0.96), but not intervention (aRR = 1.02, 95% CI: 1.00 to 1.04); use was not predictive of suppression in either arm. CONCLUSIONS The Sustainable East Africa Research in Community Health intervention improved ART uptake and viral suppression among PWH reporting hazardous alcohol use and eliminated gaps in ART uptake between PWH with hazardous and no/nonhazardous use. Patient-centered HIV care may decrease barriers to HIV care for PWH with hazardous alcohol use.

Abstract
Low-cost interventions are needed to reduce alcohol use among persons with HIV (PWH) in low-income settings. Brief alcohol interventions hold promise, and technology may efficiently deliver brief intervention components with high frequency. We conducted a costing study of the components of a randomized trial that compared a counselling-based intervention with two in-person one-on-one sessions supplemented by booster sessions to reinforce the intervention among PWH with unhealthy alcohol use in southwest Uganda. Booster sessions were delivered twice weekly by two-way short message service (SMS) or Interactive Voice Response (IVR), i.e. via technology, or approximately monthly via live calls from counsellors. We found no significant intervention effects compared to the control, however the cost of the types of booster sessions differed. Start up and recurring costs for the technology-delivered booster sessions were 2.5 to 3 times the cost per participant of the live-call delivered booster intervention for 1000 participants. These results suggest technology-based interventions for PWH are unlikely to be lower cost than person-delivered interventions unless they are at very large scale.

Abstract
Hazardous drinking by persons living with HIV (PLHIV) is a well-established determinant of sub-optimal HIV care and treatment outcomes. Despite this, to date, few interventions have sought to reduce hazardous drinking among PLHIV in sub-Saharan Africa (SSA). We describe an iterative cultural adaptation of an evidence-based multi-session alcohol reduction intervention for PLHIV in southwestern Uganda. The adaptation process included identifying core, theoretically informed, intervention elements, and conducting focus group discussions and cognitive interviews with community members, HIV clinic staff and patients to modify key intervention characteristics for cultural relevance and saliency. Adaptation of evidence-based alcohol reduction interventions can be strengthened by the inclusion of the target population and key stakeholders in shaping the content, while retaining fidelity to core intervention elements.

Abstract
BACKGROUND AND AIMS Culturally relevant and feasible interventions are needed to address limited professional resources in sub-Saharan Africa for behaviorally treating the dual epidemics of HIV and alcohol use disorder. This study tested the efficacy of a cognitive-behavioral therapy (CBT) intervention to reduce alcohol use among HIV-infected outpatients in Eldoret, Kenya. DESIGN Randomized clinical trial. SETTING A large HIV outpatient clinic in Eldoret, Kenya, affiliated with the Academic Model Providing Access to Healthcare collaboration. PARTICIPANTS A total of 614 HIV-infected outpatients [312 CBT; 302 healthy life-styles (HL); 48.5% male; mean age: 38.9 years; mean education 7.7 years] who reported a minimum of hazardous or binge drinking. INTERVENTION AND COMPARATOR A culturally adapted six-session gender-stratified group CBT intervention compared with HL education, each delivered by paraprofessionals over six weekly 90-minute sessions with a 9-month follow-up. MEASUREMENTS Primary outcome measures were percentage of drinking days (PDD) and mean drinks per drinking day (DDD) computed from retrospective daily number of drinks data obtained by use of the time-line follow-back from baseline to 9 months post-intervention. Exploratory analyses examined unprotected sex and number of partners. FINDINGS Median attendance was six sessions across condition. Retention at 9 months post-intervention was high and similar by condition: CBT 86% and HL 83%. PDD and DDD marginal means were significantly lower in CBT than HL at all three study phases. Maintenance period, PDD - CBT = 3.64 (0.696), HL = 5.72 (0.71), mean difference 2.08, 95% confidence interval (CI) = 0.13 - 4.04; DDD - CBT = 0.66 (0.96), HL = 0.98 (0.098), mean difference = 0.31, 95% CI = 0.05 - 0.58. Risky sex decreased over time in both conditions, with a temporary effect for CBT at the 1-month follow-up. CONCLUSIONS A cognitive-behavioral therapy intervention was more efficacious than healthy lifestyles education in reducing alcohol use among HIV-infected Kenyan outpatient drinkers.

Implementation science outcomes of a gender-focused HIV and alcohol risk-reduction intervention in usual-care settings in South Africa. Drug Alcohol Depend 2020; 215:108206. [PMID: 32771909 PMCID: PMC7502463 DOI: 10.1016/j.drugalcdep.2020.108206] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 07/16/2020] [Accepted: 07/17/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND South Africa has the highest HIV prevalence globally, which disproportionately affects women. Hazardous alcohol use reduces antiretroviral adherence which can lead to adverse health. Few evidence-based interventions addressing hazardous alcohol use and HIV have been implemented in real-world settings. This study aimed to evaluate implementation outcomes from the Women's Health CoOp (WHC)-an evidence-based gender-focused HIV intervention-which was implemented in Cape Town. METHODS We conducted this implementation science trial using a modified stepped-wedge design. Four health clinics were paired with four substance use rehabilitation programs and randomized into four cycles. Women living with HIV and who use alcohol or other drugs were recruited into each cycle (n = 120 each cycle). We assessed adoption, acceptability, appropriateness, cost, and fidelity using a mixed methods approach. RESULTS Adoption: 100 % of staff trained in the WHC and designated as interventionists delivered one or more workshops. Acceptability: Interventionists found the WHC content beneficial to their patients and the WHC improved connections between clinical units in facilities. Appropriateness: The WHC aligned with facility goals to improve antiretroviral adherence and reduce alcohol use; however, there were implementation challenges, including staff shortages, stigma, and few places to refer women for supportive services. Cost: The cost of implementing the WHC was 20.59 ZAR (1.40 USD) per attendee. Fidelity: Interventionists implemented the WHC with high fidelity and quality. CONCLUSIONS The findings suggest it is feasible to integrate the WHC into usual-care settings. Future efforts to scale up the intervention will need to address social and structural implementation challenges. TRIAL REGISTRATION NCT02733003 approved 1/21/2016.

Abstract
BACKGROUND Poorer working memory function has previously been associated with alcohol misuse, Human Immunodeficiency Virus (HIV) positive status, and risky behavior. Poorer working memory performance relates to alterations in specific brain networks. OBJECTIVE The current study examined if there was a relationship between brain networks involved in working memory and reported level of alcohol consumption during an individual's period of heaviest use. Furthermore, we examined whether HIV status and the interaction between HIV and alcohol consumption was associated with differences in these brain networks. METHODS Fifty adults, 26 of whom were HIV positive, engaged in an n-back working memory task (0-back and 2-back trials) administered in a magnetic resonance imaging (MRI) scanner. The Kreek- McHugh-Schluger-Kellogg (KMSK) scale of alcohol consumption was used to characterize an individual's period of heaviest use and correlates well with their risk for alcohol dependence. Connectivity analyses were conducted using data collected during n-back task. RESULTS Functional connectivity differences associated with greater alcohol consumption included negative connectivity, primarily from parietal attention networks to frontal networks. Greater alcohol consumption was also associated with positive connectivity from working memory nodes to the precuneus and paracingulate. HIV positive status was associated with more nodes of negative functional connectivity relative to alcohol consumption history alone, particularly in the frontoparietal networks. The HIV positive individuals with heavier drinking history related to negative fronto-parietal connectivity, along with positive connectivity from working memory nodes to mesolimbic regions. CONCLUSION Findings allow for a better understanding of brain networks affected by HIV and alcohol and may provide avenues for interventions.

Abstract
Background Among HIV+ patients, alcohol use is a highly prevalent risk factor for both HIV transmission and poor adherence to HIV treatment. The large-scale implementation of effective interventions for treating alcohol problems remains a challenge in low-income countries with generalized HIV epidemics. It is essential to consider an intervention’s cost-effectiveness in dollars-per-health-outcome, and the long-term economic impact —or “return on investment” in monetary terms. Methods We conducted a cost-benefit analysis, measuring economic return on investment, of a task-shifted cognitive-behavioral therapy (CBT) intervention delivered by paraprofessionals to reduce alcohol use in a modeled cohort of 13,440 outpatients in Kenya. In our base-case, we estimated the costs and economic benefits from a societal perspective across a six-year time horizon, with a 3% annual discount rate. Costs included all costs associated with training and administering task-shifted CBT therapy. Benefits included the economic impact of lowered HIV incidence as well as the improvements in household and labor-force productivity. We conducted univariate and multivariate probabilistic sensitivity analyses to test the robustness of our results. Results Under the base case, total costs for CBT rollout was $554,000, the value of benefits were $628,000, and the benefit-to-cost ratio was 1.13. Sensitivity analyses showed that under most assumptions, the benefit-to-cost ratio remained above unity indicating that the intervention was cost-saving (i.e., had positive return on investment). The duration of the treatment effect most effected the results in sensitivity analyses. Conclusions CBT can be effectively and economically task-shifted to paraprofessionals in Kenya. The intervention can generate not only reductions in morbidity and mortality, but also economic savings for the health system in the medium and long term. The findings have implications for other countries with generalized HIV epidemics, high prevalence of alcohol consumption, and shortages of mental health professionals. Trial registration This paper uses data derived from “Cognitive Behavioral Treatment to Reduce Alcohol Use Among HIV-Infected Kenyans (KHBS)” with ClinicalTrials.gov registration NCT00792519 on 11/17/2008; and preliminary data from “A Stage 2 Cognitive-behavioral Trial: Reduce Alcohol First in Kenya Intervention” (NCT01503255, registered on 12/16/2011).

Abstract
We evaluated the efficacy of a brief motivational intervention (MI) counseling in reducing alcohol consumption among persons living with HIV/AIDS in Kampala, Uganda. Persons living with HIV/AIDS with Alcohol Use Disorders Identification Tool (AUDIT) score ≥3 points were randomized to either standardized positive prevention counseling alone or in combination with alcohol brief MI counseling. The mean change in AUDIT-C scores over 6 months was compared by treatment arm. The mean (standard deviation [SD]) AUDIT-C scores were 6.3 (2.3) and 6.8 (2.3) for control and MI arms ( P = .1) at baseline, respectively, and change in mean AUDIT-C score was not statistically different between arms over the 6 months ( P = .8). However, there was a statistically significant decrease in mean AUDIT-C score (-1.10; 95% confidence interval: -2.19 to -0.02, P = .046) among women in the MI arm. There was a nondifferential reduction in alcohol consumption overall, but MI appeared effective among women only. Studies with more than 1 counseling session and evaluation of gender differences in treatment response are needed.

Abstract
Background The overarching goal of health policies is to maximize health and societal benefits. Economic evaluations can play a vital role in assessing whether or not such benefits occur. This paper reviews the application of modelling techniques in economic evaluations of drug and alcohol interventions with regard to (i) modelling paradigms themselves; (ii) perspectives of costs and benefits and (iii) time frame. Methods Papers that use modelling approaches for economic evaluations of drug and alcohol interventions were identified by carrying out searches of major databases. Results Thirty eight papers met the inclusion criteria. Overall, the cohort Markov models remain the most popular approach, followed by decision trees, Individual based model and System dynamics model (SD). Most of the papers adopted a long term time frame to reflect the long term costs and benefits of health interventions. However, it was fairly common among the reviewed papers to adopt a narrow perspective that only takes into account costs and benefits borne by the health care sector. Conclusions This review paper informs policy makers about the availability of modelling techniques that can be used to enhance the quality of economic evaluations for drug and alcohol treatment interventions.

Alcohol Clin Exp Res 2015; 39:2179-88. [PMID: 26463727 PMCID: PMC5651989 DOI: 10.1111/acer.12890] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2015] [Accepted: 08/26/2015] [Indexed: 11/27/2022]
Abstract
BACKGROUND In the current report, we ask if targeting a cognitive behavioral therapy (CBT)-based intervention aimed at reducing hazardous alcohol consumption to HIV-infected persons in East Africa would have a favorable value at costs that are feasible for scale-up. METHODS Using a computer simulation to inform HIV prevention decisions in East Africa, we compared 4 different strategies for targeting a CBT intervention-(i) all HIV-infected persons attending clinic; (ii) only those patients in the pre-antiretroviral therapy (ART) stages of care; (iii) only those patients receiving ART; and (iv) only those patients with detectable viral loads (VLs) regardless of disease stage. We define targeting as screening for hazardous alcohol consumption (e.g., using the Alcohol Use Disorders Identification Test and offering the CBT intervention to those who screen positive). We compared these targeting strategies to a null strategy (no intervention) or a hypothetical scenario where an alcohol intervention was delivered to all adults regardless of HIV status. RESULTS An intervention targeted to HIV-infected patients could prevent 18,000 new infections, add 46,000 quality-adjusted life years (QALYs), and yield an incremental cost-effectiveness ratio of $600/QALY compared to the null scenario. Narrowing the prioritized population to only HIV-infected patients in pre-ART phases of care results in 15,000 infections averted, the addition of 21,000 QALYs and would be cost-saving, while prioritizing based on an unsuppressed HIV-1 VL test results in 8,300 new infections averted, adds 6,000 additional QALYs, and would be cost-saving as well. CONCLUSIONS Our results suggest that targeting a cognitive-based treatment aimed at reducing hazardous alcohol consumption to subgroups of HIV-infected patients provides favorable value in comparison with other beneficial strategies for HIV prevention and control in this region. It may even be cost-saving under certain circumstances.
