Dave S, Peter T, Fogarty C, Karatzas N, Belinsky N, Pant Pai N. Which community-based HIV initiatives are effective in achieving UNAIDS 90-90-90 targets? A systematic review and meta-analysis of evidence (2007-2018). PLoS One 2019; 14:e0219826. [PMID: 31314764 PMCID: PMC6636761 DOI: 10.1371/journal.pone.0219826] [Citation(s) in RCA: 45] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2018] [Accepted: 07/02/2019] [Indexed: 12/21/2022] Open
Abstract
Background Reaching the Joint United Nations Programme on HIV/AIDS (UNAIDS) 90-90-90 targets to end the HIV epidemic relies on effective interventions that engage untested HIV+ individuals and retain them in care. Evidence on community-based interventions through the lens of the targets has not yet been synthesized, reflecting a knowledge gap. We conducted a systematic review and meta-analysis to shed light on successful community-based interventions that have been effective in contributing, directly or indirectly, towards the UNAIDS 90-90-90 targets: knowledge of HIV status, linkage to care/on treatment, and viral suppression. Linkage to care was also included in this review due to the limitations of studies. Methods We conducted a systematic review and meta-analysis of the period 2007–2018. Eleven databases were searched to identify community-based interventions designed to improve knowledge of HIV status (in particular HIV testing), linkage to care/on treatment, and/or viral suppression. Eligible studies were classified by intervention, population, country income level, outcomes and success. Success was defined as interventions demonstrating statistical significance between intervention and control group or that reached any target by proportion; 90% testing, 81% linked to care/on treatment and 73% viral suppression. Results Of 82 eligible studies, 51.2% (42/82) reported on HIV testing (first 90), 20.7% (17/82) on linkage to care/ on treatment (second 90), and 45.1% (37/82) on viral suppression (third 90). In all, 67.1% (55/82) of studies reported success; 21 studies on the first 90, 9 towards linkage to care/on treatment, and 25 towards the third. By strategies, 36.6% deployed community workers/peers, 22% used combined test and treat strategies, 12.2% used educational methods, 8.5% used mobile testing, 7.3% used campaigns and 13.4% used technology. For HIV testing/linkage, combined test/treat interventions were often used, for viral suppression, educational interventions and technologies were commonly deployed. Our pooled analysis suggested that deployment of community health care workers/peer workers significantly improved viral suppression (pooled OR: 1.40 95% CI 1.06–1.86). Of the studies published after 2014, 50.0% reported metrics aligned with UNAIDS targets. Conclusions Data on linkage to care/on treatment (second target) remained weak, because many studies reported successes on the first and third targets. Stratification by targets and country income levels is informative and guides adaptation of successful interventions in comparable settings. Consistent reporting of clear metrics aligned with UNAIDS targets will aid in synergy of study data with programmatic data that will help reportage. Exploration of innovative interventions, for engagement and linkage and deployment of community/ peer workers is strongly encouraged.

Long-Term Effects of Psychological Interventions to Improve Adherence to Antiretroviral Treatment in HIV-Infected Persons: A Systematic Review and Meta-Analysis.

Abstract
We examined the efficacy of psychological adherence-enhancing interventions (AEIs) compared with usual care in HIV-infected adults under antiretroviral treatment (ART) by focusing on adherence and clinical HIV markers as outcomes in the short term and long term. We searched relevant databases for controlled studies that compared psychological AEIs with usual care. We included 31 comparisons from 27 individual studies in our meta-analyses. Psychological AEIs were significantly superior to usual care in improving adherence [standardized mean difference (SMD) 0.30, 95% CI 0.20-0.40] and reducing HIV viral load (SMD 0.15, 0.07-0.23) at the end of treatment. At the last follow-up, we found no difference between psychological AEIs and usual care, neither on adherence (SMD 0.07, -0.11-0.24) nor on clinical markers (SMD 0.06, -0.03-0.15). After excluding outliers from the analyses, between-study heterogeneity was small, and we did not identify any relevant moderators of intervention effects. In summary, psychological AEIs may significantly improve ART adherence and HIV viral load compared with usual care in the short term, but fail to be superior in achieving long-lasting improvements on ART adherence and clinical HIV markers as compared with usual care. Owing to limited quality and the majority of studies being conducted in the United States or Europe, our results have to be interpreted with caution, and are most relevant to the United States and Europe. The consistently reported difficulties to achieve sustained ART adherence improvements in previous and the present meta-analyses highlight the need to focus on maintaining ART adherence improvements in future research.

Abstract
OBJECTIVE This study reviews the published literature on the use of video-based decision aids (DA) for patients. The authors describe the areas of medicine in which video-based patient DA have been evaluated, the medical decisions targeted, their reported impact, in which countries studies are being conducted, and publication trends. METHOD The literature review was conducted systematically using Medline, Embase, CINAHL, PsychInfo, and Pubmed databases from inception to 2016. References of identified studies were reviewed, and hand-searches of relevant journals were conducted. RESULTS 488 studies were included and organized based on predefined study characteristics. The most common decisions addressed were cancer screening, risk reduction, advance care planning, and adherence to provider recommendations. Most studies had sample sizes of fewer than 300, and most were performed in the United States. Outcomes were generally reported as positive. This field of study was relatively unknown before 1990s but the number of studies published annually continues to increase. CONCLUSION Videos are largely positive interventions but there are significant remaining knowledge gaps including generalizability across populations. PRACTICE IMPLICATIONS Clinicians should consider incorporating video-based DA in their patient interactions. Future research should focus on less studied areas and the mechanisms underlying effective patient decision aids.

Quality of life, anxiety and depression in patients with HIV/AIDS who present poor adherence to antiretroviral therapy: a cross-sectional study in Salvador, Brazil. Braz J Infect Dis 2017; 21:507-514. [PMID: 28535397 PMCID: PMC9425484 DOI: 10.1016/j.bjid.2017.04.004] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Revised: 04/17/2017] [Accepted: 04/17/2017] [Indexed: 11/29/2022] Open
Abstract
The introduction of highly active antiretroviral therapy marked a major gain in efficacy of HIV/AIDS treatment and a reduction in morbidity and mortality of the infected patients. However, high levels of adherence are required to obtain virologic suppression. In Brazil, the policy of free and universal access to antiretroviral therapy has been in place since 1996, although there are reports of poor adherence. OBJECTIVE To define the clinical, demographic and psychological characteristics, and quality of life of patients with HIV/AIDS who present poor adherence to highly active antiretroviral therapy. METHODS This was a cross-sectional study. To be included in the study patients had to be 18 through 65 years old, diagnosed with HIV/AIDS, having the two previous viral loads above 500 copies, a surrogate for poor adherence to antiretrovirals. The following instruments were applied to all eligible patients: the sociodemographic questionnaire "Adherence Follow-up Questionnaire", the Beck Depression Inventory (BDI-II), the Beck Anxiety Inventory (BAI), and the 36-Item Short Form Survey. RESULTS 47 patients were evaluated, 70.2% were female, mean age of 41.9 years (±10.5), 46.8% were single, 51.1% self-reported adherence ≥95%, 46.8% mentioned depression as the main reason for not taking the medication, 59.5% presented symptoms of moderate to severe depression, and 44.7% presented symptoms of moderate to severe anxiety. Finally, regarding health-related quality of life these patients obtained low scores in all dimensions, physical component summary of 43.96 (±9.64) and mental component summary of 33.19 (±13.35). CONCLUSION The psychological component is considered to be fundamental in the management of HIV/AIDS patients. Psychoeducation should be conducted at the initial evaluation to reduce negative beliefs regarding antiretroviral therapy Assessment of anxiety and depression symptoms should be done throughout therapy as both psycological conditions are associated with patient adherence, success of treatment, and ultimately with patients' quality of life.

Interventions to improve adherence to antiretroviral therapy: a systematic review and network meta-analysis. Lancet HIV 2016; 4:e31-e40. [PMID: 27863996 DOI: 10.1016/s2352-3018(16)30206-5] [Citation(s) in RCA: 170] [Impact Index Per Article: 21.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2016] [Revised: 09/13/2016] [Accepted: 09/16/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND High adherence to antiretroviral therapy is crucial to the success of HIV treatment. We evaluated comparative effectiveness of adherence interventions with the aim of informing the WHO's global guidance on interventions to increase adherence. METHODS For this systematic review and network meta-analysis, we searched for randomised controlled trials of interventions that aimed to improve adherence to antiretroviral therapy regimens in populations with HIV. We searched Cochrane Central Register of Controlled Trials, Embase, and MEDLINE for reports published up to July 16, 2015, and searched major conference abstracts from Jan 1, 2013, to July 16, 2015. We extracted data from eligible studies for study characteristics, interventions, patients' characteristics at baseline, and outcomes for the study populations of interest. We used network meta-analyses to compare adherence and viral suppression for all study settings (global network) and for studies in low-income and middle-income countries only (LMIC network). FINDINGS We obtained data from 85 trials with 16 271 participants. Short message service (SMS; text message) interventions were superior to standard of care in improving adherence in both the global network (odds ratio [OR] 1·48, 95% credible interval [CrI] 1·00-2·16) and in the LMIC network (1·49, 1·04-2·09). Multiple interventions showed generally superior adherence to single interventions, indicating additive effects. For viral suppression, only cognitive behavioural therapy (1·46, 1·05-2·12) and supporter interventions (1·28, 1·01-1·71) were superior to standard of care in the global network; none of the interventions improved viral response in the LMIC network. For the global network, the time discrepancy (whether the study outcome was measured during or after intervention was withdrawn) was an effect modifier for both adherence to antiretroviral therapy (coefficient estimate -0·43, 95% CrI -0·75 to -0·11) and viral suppression (-0·48; -0·84 to -0·12), suggesting that the effects of interventions wane over time. INTERPRETATION Several interventions can improve adherence and viral suppression; generally, their estimated effects were modest and waned over time. FUNDING WHO.

Abstract
Barriers to antiretroviral therapy (ART) adherence among pregnant women are varied and complex. This study explored the constructs of a theoretical model, the Health Belief Model (HBM) to understand and predict ART adherence among pregnant women in Guyana. A cross-sectional study surveyed 108 pregnant women attending 11 primary care clinics. ART adherence ranging from the past weekend to three months was assessed through self-reports, and health beliefs with the Adherence Determinants Questionnaire (ADQ). Constructs with sufficient variation in responses were tested for association with the level of adherence using Spearman's rank correlation coefficient and test. Sixty-seven per cent (72) of the women reported being always adherent. Although there was positive endorsement of ART treatment and adherence, the HBM did not help in understanding or predicting ART adherence in this population. Only one item from the perceived susceptibility construct was significantly associated (p = 0.009) with adherence. Interventions are warranted to address ART adherence in this population, as 19% of the women were recently non-adherent. Although the ADQ did not contribute to a deeper understanding or provide insight into pathways that can be targeted for intervention, theoretical models can play a key role in identifying these pathways.

Abstract
INTRODUCTION This review assesses the impact of prevention interventions for people living with HIV on HIV-related mortality, morbidity, retention in care, quality of life, and prevention of ongoing HIV transmission in resource-limited settings (RLSs). METHODS We conducted a systematic review of studies reporting the results of prevention interventions for people living with HIV in RLS published between January 2000 and August 2014. Standardized methods of searching and data abstraction were used. RESULTS Ninety-two studies met the eligibility criteria: 24 articles related to adherence counseling and support, 13 on risk reduction education and condom provision, 19 on partner HIV testing and counseling, 14 on provision of family planning services, and 22 on assessment and treatment of other sexually transmitted infections. Findings indicate good evidence that adherence counseling and sexually transmitted infection treatment can have a high impact on morbidity, whereas risk reduction education, partner HIV testing and counseling, and family planning counseling can prevent transmission of HIV. More limited evidence was found to support the impact of these interventions on retention in care and quality of life. Most studies did not report cost information, making it difficult to draw conclusions about the cost-effectiveness of these interventions. CONCLUSIONS This evidence suggests that these prevention interventions, if brought to sufficient scale and coverage, can help support and optimize the impact of core treatment and prevention interventions in RLS. Further operational research with more rigorous study designs, and ideally with biomarkers and costing information, is needed to determine the best model for providing these interventions in RLS.

Abstract
: Health communication has played a pivotal role in HIV prevention efforts since the beginning of the epidemic. The recent paradigm of combination prevention, which integrates behavioral, biomedical, and structural interventions, offers new opportunities for employing health communication approaches across the entire continuum of care. We describe key areas where health communication can significantly enhance HIV treatment, care, and prevention, presenting evidence from interventions that include health communication components. These interventions rely primarily on interpersonal communication, especially individual and group counseling, both within and beyond clinical settings to enhance the uptake of and continued engagement in care. Many successful interventions mobilize a network of trained community supporters or accompagnateurs, who provide education, counseling, psychosocial support, treatment supervision, and other pragmatic assistance across the care continuum. Community treatment supporters reduce the burden on overworked medical providers, engage a wider segment of the community, and offer a more sustainable model for supporting people living with HIV. Additionally, mobile technologies are increasingly seen as promising avenues for ongoing cost-effective communication throughout the treatment cascade. A broader range of communication approaches, traditionally employed in HIV prevention efforts, that address community and sociopolitical levels through mass media, school- or workplace-based education, and entertainment modalities may be useful to interventions seeking to address the full care continuum. Future interventions would benefit from development of a framework that maps appropriate communication theories and approaches onto each step of the care continuum to evaluate the efficacy of communication components on treatment outcomes.

Abstract
BACKGROUND Adherence is one of the most important determinants of viral suppression and drug resistance in HIV-infected people receiving antiretroviral therapy (ART). METHODS We examined the association between long-term mortality and poor adherence to ART in DART trial participants in Uganda and Zimbabwe randomly assigned to receive laboratory and clinical monitoring (LCM), or clinically driven monitoring (CDM). Since over 50% of all deaths in the DART trial occurred during the first year on ART, we focussed on participants continuing ART for 12 months to investigate the implications of longer-term adherence to treatment on mortality. Participants' ART adherence was assessed by pill counts and structured questionnaires at 4-weekly clinic visits. We studied the effect of recent adherence history on the risk of death at the individual level (odds ratios from dynamic logistic regression model), and on mortality at the population level (population attributable fraction based on this model). Analyses were conducted separately for both randomization groups, adjusted for relevant confounding factors. Adherence behaviour was also confounded by a partial factorial randomization comparing structured treatment interruptions (STI) with continuous ART (CT). RESULTS In the CDM arm a significant association was found between poor adherence to ART in the previous 3-9 months with increased mortality risk. In the LCM arm the association was not significant. The odds ratios for mortality in participants with poor adherence against those with optimal adherence was 1.30 (95% CI 0.78,2.10) in the LCM arm and 2.18 (1.47,3.22) in the CDM arm. The estimated proportions of deaths that could have been avoided with optimal adherence (population attributable fraction) in the LCM and CDM groups during the 5 years follow-up period were 16.0% (95% CI 0.7%,31.6%) and 33.1% (20.5%,44.8%), correspondingly. CONCLUSIONS Recurrent poor adherence determined even through simple measures is associated with high mortality both at individual level as well as at the ART programme level. The number of lives saved through effective interventions to improve adherence could be considerable particularly for individuals monitored without using CD4 cell counts. The findings have important implications for clinical practice and for developing interventions to enhance adherence.

Abstract
The aim of this study was to compare the retention in medical care and antiretroviral (ARV) treatment of individuals living with HIV and AIDS to antiretroviral therapy in southern Brazil according to their "race" or skin color. This study is part of a 225-day prospective trial, comprising 7 interviews, in which an intervention designed to improve adherence to treatment was tested. A convenience sample of 73 individuals living with HIV and/or AIDS enrolled in this follow-up procedure. The mean length of continuance in treatment was 161.5 (standard deviation [SD] = 18.6; 95% confidence interval [CI] = 125-198) and 138.4 (SD = 14.1; 95% C.I. = 111-166) days in the "nonwhite" and "white" categories, respectively. There was no significant difference between the 2 categories, χ(2)(1, n = 72) = 0.76, P = .38, which include similar levels of retention in medical care and treatment with ARV medications between groups of individuals categorized as white and nonwhite in this sample.

Abstract
BACKGROUND Health consumers increasingly want access to accurate, evidence-based information about their medications. Currently, education about medications (that is, information that is designed to achieve health or illness related learning) is provided predominantly via spoken communication between the health provider and consumer, sometimes supplemented with written materials. There is evidence, however, that current educational methods are not meeting consumer needs. Multimedia educational programs offer many potential advantages over traditional forms of education delivery. OBJECTIVES To assess the effects of multimedia patient education interventions about prescribed and over-the-counter medications in people of all ages, including children and carers. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2011, Issue 6), MEDLINE (1950 to June 2011), EMBASE (1974 to June 2011), CINAHL (1982 to June 2011), PsycINFO (1967 to June 2011), ERIC (1966 to June 2011), ProQuest Dissertation & Theses Database (to June 2011) and reference lists of articles. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-RCTs of multimedia-based patient education about prescribed or over-the-counter medications in people of all ages, including children and carers, if the intervention had been targeted for their use. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risk of bias of included studies. Where possible, we contacted study authors to obtain missing information. MAIN RESULTS We identified 24 studies that enrolled a total of 8112 participants. However, there was significant heterogeneity in the comparators used and the outcomes measured, which limited the ability to pool data. Many of the studies did not report sufficient information in their methods to allow judgment of their risk of bias. From the information that was reported, three of the studies had a high risk of selection bias and one was at high risk of bias due to lack of blinding of the outcome assessors. None of the included studies reported the minimum clinically important difference for the outcomes that were measured. We have therefore reported results from the studies but have been unable to interpret whether differences were of clinical importance.The main findings of the review are as follows.Knowledge: There is low quality evidence that multimedia education was more effective than usual care (non-standardised education provided as part of usual clinical care) or no education (standardised mean difference (SMD) 1.04, 95% confidence interval (CI) 0.49 to 1.58, six studies with 817 participants). There was considerable statistical heterogeneity (I(2) = 89%), however, all but one of the studies favoured the multimedia group. There is moderate quality evidence that multimedia education was not more effective at improving knowledge than control multimedia interventions (i.e. multimedia programs that do not provide information about the medication) (mean difference (MD) of knowledge scores 2.78%, 95% CI -1.48 to 7.0, two studies with 568 participants). There is moderate quality evidence that multimedia education was more effective when added to a co-intervention (written information or brief standardised instructions provided by a health professional) compared with the co-intervention alone (MD of knowledge scores 24.59%, 95% CI 22.34 to 26.83, two studies with 381 participants).Skill acquisition: There is moderate quality evidence that multimedia education was more effective than usual care or no education (MD of inhaler technique score 18.32%, 95% CI 11.92 to 24.73, two studies with 94 participants) and written education (risk ratio (RR) of improved inhaler technique 2.14, 95% CI 1.33 to 3.44, two studies with 164 participants). There is very low quality evidence that multimedia education was equally effective as education by a health professional (MD of inhaler technique score -1.01%, 95% CI -15.75 to 13.72, three studies with 130 participants).Compliance with medications: There is moderate quality evidence that there was no difference between multimedia education and usual care or no education (RR of complying 1.02, 95% CI 0.96 to 1.08, two studies with 4552 participants).We could not determine the effect of multimedia education on other outcomes, including patient satisfaction, self-efficacy and health outcomes, due to an inadequate number of studies from which to draw conclusions. AUTHORS' CONCLUSIONS This review provides evidence that multimedia education about medications is more effective than usual care (non-standardised education provided by health professionals as part of usual clinical care) or no education, in improving both knowledge and skill acquisition. It also suggests that multimedia education is at least equivalent to other forms of education, including written education and education provided by a health professional. However, this finding is based on often low quality evidence from a small number of trials. Multimedia education about medications could therefore be considered as an adjunct to usual care but there is inadequate evidence to recommend it as a replacement for written education or education by a health professional. Multimedia education may be considered as an alternative to education provided by a health professional, particularly in settings where provision of detailed education by a health professional is not feasible. More studies evaluating multimedia educational interventions are required in order to increase confidence in the estimate of effect of the intervention.Conclusions regarding the effect of multimedia education were limited by the lack of information provided by study authors about the educational interventions, and variability in their content and quality. Studies testing educational interventions should provide detailed information about the interventions and comparators. Research is required to establish a framework that is specific for the evaluation of the quality of multimedia educational programs. Conclusions were also limited by the heterogeneity in the outcomes reported and the instruments used to measure them. Research is required to identify a core set of outcomes which should be measured when evaluating patient educational interventions. Future research should use consistent, reliable and validated outcome measures so that comparisons can be made between studies.

Abstract
The rollout of antiretroviral therapy (ART) significantly reduced human immunodeficiency virus (HIV)-related morbidity and mortality, but good clinical outcomes depend on access and adherence to treatment. In resource-limited settings, where over 90% of the world's HIV-infected population resides, data on barriers to treatment are emerging that contribute to low rates of uptake in HIV testing, linkage to and retention in HIV care systems, and suboptimal adherence rates to therapy. A review of the literature reveals limited evidence to inform strategies to improve access and adherence with the majority of studies from sub-Saharan Africa. Data from observational studies and randomized controlled trials support home-based, mobile and antenatal care HIV testing, task-shifting from doctor-based to nurse-based and lower level provider care, and adherence support through education, counseling and mobile phone messaging services. Strategies with more limited evidence include targeted HIV testing for couples and family members of ART patients, decentralization of HIV care, including through home- and community-based ART programs, and adherence promotion through peer health workers, treatment supporters, and directly observed therapy. There is little evidence for improving access and adherence among vulnerable groups such as women, children and adolescents, and other high-risk populations and for addressing major barriers. Overall, studies are few in number and suffer from methodological issues. Recommendations for further research include health information technology, social-level factors like HIV stigma, and new research directions in cost-effectiveness, operations, and implementation. Findings from this review make a compelling case for more data to guide strategies to improve access and adherence to treatment in resource-limited settings.

Abstract
To assess the effectiveness of a psychosocial individual intervention to improve adherence to ART in a Brazilian reference-center, consenting PLHIV with viral load >50 copies/ml were selected. After 4 weeks of MEMS cap use, participants were randomized into an intervention group (IG) (n = 64) or control group (CG) (n = 57). CG received usual care only. The IG participated in a human rights-based intervention approach entailing four dialogical meetings focused on medication intake scenes. Comparison between IG and CG revealed no statistically significant difference in adherence measured at weeks 8, 12, 16, 20 and 24. Viral load (VL) decreased in both groups (p < 0.0001) with no significant difference between study groups. The lower number of eligible patients than expected underpowered the study. Ongoing qualitative analysis should provide deeper understanding of the trial results. NIH Clinical Trials: NCT00716040.

Abstract
DESCRIPTION After HIV diagnosis, timely entry into HIV medical care and retention in that care are essential to the provision of effective antiretroviral therapy (ART). Adherence to ART is among the key determinants of successful HIV treatment outcome and is essential to minimize the emergence of drug resistance. The International Association of Physicians in AIDS Care convened a panel to develop evidence-based recommendations to optimize entry into and retention in care and ART adherence for people with HIV. METHODS A systematic literature search was conducted to produce an evidence base restricted to randomized, controlled trials and observational studies with comparators that had at least 1 measured biological or behavioral end point. A total of 325 studies met the criteria. Two reviewers independently extracted and coded data from each study using a standardized data extraction form. Panel members drafted recommendations based on the body of evidence for each method or intervention and then graded the overall quality of the body of evidence and the strength for each recommendation. RECOMMENDATIONS Recommendations are provided for monitoring entry into and retention in care, interventions to improve entry and retention, and monitoring of and interventions to improve ART adherence. Recommendations cover ART strategies, adherence tools, education and counseling, and health system and service delivery interventions. In addition, they cover specific issues pertaining to pregnant women, incarcerated individuals, homeless and marginally housed individuals, and children and adolescents, as well as substance use and mental health disorders. Recommendations for future research in all areas are also provided.

Abstract
BACKGROUND Crack cocaine use undermines adherence to highly active antiretroviral therapy (HAART). This pilot randomized clinical trial tested the feasibility and efficacy of 2 interventions based on the Information-Motivation-Behavioral Skill model to improve HAART adherence and reduce crack cocaine problems. METHODS Participants were 54 adults with crack cocaine use and HIV with <90% HAART adherence. Most participants were African-American (82%) heterosexual (59%), and crack cocaine dependent (92%). Average adherence was 58% in the past 2 weeks. Average viral loads (VL) were detectable (logVL 2.97). The interventions included 6 sessions of Motivational Interviewing plus feedback and skills building (MI+), or Video information plus debriefing (Video+) over 8 weeks. Primary outcomes were adherence by 14-day timeline follow-back and Addiction Severity Index (ASI) Drug Composite Scores at 3 and 6 months. Repeated measure ANOVA assessed main effects of the interventions and interactions by condition. RESULTS Significant increases in adherence and reductions in ASI Drug Composite Scores occurred in both conditions by 3 months and were maintained at 6 months, representing medium effect sizes. No between group differences were observed. No VL changes were observed in either group. Treatment credibility, retention, and satisfaction were high and not different by condition. CONCLUSIONS A counseling and a video intervention both improved adherence and drug problems durably among people with crack cocaine use and poor adherence in this pilot study. The interventions should be tested further among drug users with poor adherence. Video interventions may be feasible and scalable for people with HIV and drug use.

Ignoring the group in group-level HIV/AIDS intervention trials: a review of reported design and analytic methods. AIDS 2011; 25:989-96.

Abstract
OBJECTIVES Studies evaluating the efficacy of HIV/AIDS interventions often involve the random assignment of groups of participants or the treatment of participants in groups. These studies require analytic methods that take within-group correlation into account. We reviewed published studies to determine the extent to which within-group correlation was dealt with properly. DESIGN We reviewed group-randomized trials (GRTs) and individually randomized group treatment (IRGT) trials published in HIV/AIDS and general public health journals 2005-2009. METHODS At least two of the authors reviewed each article, recording descriptive characteristics, sample size estimation methods, analytic methods, and judgments about whether the methods took intraclass correlation into account properly. RESULTS Of those articles including sufficient information to judge whether analytic methods were correct, only 24% used only appropriate methods for dealing with the intraclass correlation. The percentages differed substantially for GRTs (41.7%) and IRGT trials (8.0%). Most of the articles (69.2%) also made no mention of a priori sample size estimation. CONCLUSION A majority of the articles in our review reported analyses ignoring the intraclass correlation. This practice may result in underestimated variance, inappropriately small P values, and incorrect conclusions about the effectiveness of interventions. Previous trials that were analyzed incorrectly need to be re-analyzed, and future trials should be designed and analyzed with appropriate methods. Also, journal reviewers and editors need to be aware of the special requirements for design and analysis of GRTs and IRGT trials and judge the quality of articles reporting on such trials according to appropriate standards.

Abstract
OBJECTIVE To test the impact of participation in a peer-based intervention for symptom management for women living with HIV infection on selected outcome measures including, symptom intensity, medication adherence, viral control, and quality of life. DESIGN Randomized clinical trial. METHODS Participants were recruited using a convenient, consecutive sampling method. Those participants randomized to the experimental condition attended seven, peer-led sessions over seven weeks. Participants randomized to the control condition received a copy of HIV Symptom Management Strategies: A Manual for People Living with HIV/AIDS. Participants completed four surveys assessing change over time in the aforementioned outcome variables. RESULTS Eighty-nine HIV-infected women followed over 14 weeks and there were no differences between the two groups on baseline demographic variables. Mixed-effects regression indicated no significant difference between groups across time in total symptom intensity score and medication adherence. There was a significant difference between groups across time for two of the nine quality of life scales - HIV Mastery (chi(2)=25.08; p<0.005) and Disclosure Worries (chi(2)=24.67; p<0.005). CONCLUSIONS In urban-dwelling women living with HIV/AIDS, results suggest that a peer-based symptom management intervention may not decrease symptom intensity or increase medication adherence. There is positive evidence that suggests that the intervention may increase some important aspects of quality of life. However, further research is warranted to elucidate the effect of peer-based interventions in achieving positive self-management outcomes.

Abstract
HIV and AIDS remain highly stigmatised. Modified directly observed therapy (m-DOT) supports antiretroviral treatment (ART) adherence but little is known about its association with perceived stigma in resource-constrained settings. In 2003, 234 HIV-infected adults enrolled in a two-arm randomised trial comparing a health centre-based m-DOT strategy with standard self-administration of ART. Data on perceived stigma were collected using Berger's HIV stigma scale prior to starting ART and after 12 months. This was a secondary analysis to examine whether perceived stigma was related to treatment delivery. Perceived stigma scores declined after 12 months of treatment from a mean of 44.9 (sd=7.6) to a mean of 41.4 (sd=7.7), (t=6.14, P<0.001). No differences were found between the mean scores of participants in both study arms. Also, no difference in scores was detected using GLM, controlling for socio-demographic characteristics and baseline scores. Findings indicate that a well managed clinic-based m-DOT does not increase perceived HIV-related stigma.

Abstract
The success of potent combination antiretroviral therapy (ART) for HIV infection is compromised primarily by failure to maintain optimal levels of adherence over the long term. Recent reviews suggest behavioral interventions to promote ART adherence can have significant effects, but these tend to be small and to diminish over time; sustained improvements in biomarkers are particularly elusive. In this article, we update current reviews, focusing specifically on the 13 studies evaluating behavioral interventions to promote ART adherence published since September 2007. We describe the range of intervention strategies employed and qualitatively summarize findings of their efficacy. In conclusion, we consider implications and offer strategies for enhancing adherence in clinic-based HIV care prior to ART initiation, at initiation, and over the course of treatment.
