RESUMO

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.

RESUMO

In countries experiencing the dual burden of HIV disease and health care worker shortages, information and communication technology tools offer the potential to help support HIV treatment adherence and secondary HIV transmission risk reduction for people living with HIV/AIDS. We conducted a randomized controlled trial (September 1, 2011-July 12, 2012) with follow-up through April 2013. Participants were recruited from two clinics affiliated with the Academic Model Providing Access to Healthcare program in western Kenya. A total of 236 participants were enrolled, randomly assigned to intervention (n = 118) or risk-assessment only control (n = 118) and followed up for 9 months. Both arms had > 0.5 log10 reduction in viral load over time (p = .0007), a clinically relevant finding. A computer-based counseling tool is feasible and acceptable in a high-volume East African HIV setting and provides evidence-based ART adherence and risk reduction support that may extend health workforce deficits.

RESUMO

Approximately 71% of HIV-infected individuals live in sub-Saharan Africa. Alcohol use increases unprotected sex, which can lead to HIV transmission. Little research examines risky sex among HIV-infected individuals in East Africa who are not sex workers. The study purpose was to examine associations with unprotected sex in a high-risk sample of 507 HIV-infected sexually active drinkers in western Kenya. They were enrolled in a trial to reduce alcohol use. Past-month baseline alcohol use and sexual behavior were assessed using the Timeline Followback. A zero-inflated negative binomial model examined associations with occurrence and frequency of unprotected sex. Results showed heavy drinking days were significantly associated with unprotected sex occurrence across gender, and with unprotected sex frequency among women. Among women, transactional sex, alcohol-related sexual expectations, condom use self-efficacy, drinking-and-protected-sex days and age were associated with unprotected sex occurrence while alcohol-related sexual expectations, depressive symptoms and condom use self-efficacy were associated with unprotected sex frequency. Among men, alcohol-related sexual expectations, condom use self-efficacy, and age were associated with unprotected sex occurrence, while drinking-and-protected-sex days were associated with unprotected sex occurrence and frequency. Findings suggest robust relationships between heavy drinking and unprotected sex. Further research is needed elucidating the temporal relationships between drinking and unprotected sex in this population.

RESUMO

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).

RESUMO

Victimization from physical and sexual violence presents global health challenges. Partner violence is higher in Kenya than Africa. Violence against drinkers and HIV-infected individuals is typically elevated, so dual vulnerabilities may further augment risk. Understanding violence risks can improve interventions. Participants were 614 HIV-infected outpatient drinkers in western Kenya enrolled in a randomized trial to reduce alcohol use. At baseline, past 90-day partner physical and sexual violence were examined descriptively and in gender-stratified regression models. We hypothesized higher reported violence against women than men, and positive violence association with HIV stigma and alcohol use across gender. Women reported significantly more current sexual (26.3 vs. 5.7%) and physical (38.9 vs. 24.8%) victimization than men. Rates were generally higher than Kenyan lifetime national averages. In both regression models, HIV stigma and alcohol-related sexual expectations were significantly associated with violence while alcohol use was not. For women, higher violence risk was also conferred by childhood violence, past-year transactional sex, and younger age. HIV-infected Kenyan drinkers, particularly women, endorse high current violence due to multiple risk factors. Findings have implications for HIV interventions. Longitudinal research is needed to understand development of risk.

RESUMO

BACKGROUND: To counteract the syndemics of HIV and alcohol in Sub-Saharan Africa, international collaborations have developed interventions to reduce alcohol consumption. Reliable and accurate methods are needed to estimate alcohol use outcomes. A direct alcohol biomarker called phosphatidylethanol (PEth) has been shown to validate heavy, daily drinking, but the literature indicates mixed results for moderate and nondaily drinkers, including among HIV-infected populations. This study examined the associations of the PEth biomarker with self-report alcohol use at 2 time points in 127 HIV-infected outpatient drinkers in western Kenya. METHODS: Participants were consecutively enrolled in a randomized clinical trial to test the efficacy of a behavioral intervention to reduce alcohol use in Eldoret, Kenya. They endorsed current alcohol use, and a minimum score of 3 on the Alcohol Use Disorders Identification Test-Consumption or consuming ≥6 drinks per occasion at least monthly in the past year. Study interviews and blood draws were conducted at baseline and at 3 months post treatment from July 2012 through September 2013. Alcohol use was assessed using the Timeline Followback questionnaire. Blood samples were analyzed for the presence of the PEth biomarker and were compared to self-reported alcohol use. We also conducted semistructured interviews with 14 study completers in February through March 2014. RESULTS: Baseline data indicated an average of moderate-heavy alcohol use: 50% drinking days and a median of 4.5 drinks per drinking day. At baseline, 46% of women (31 of 67) and 8% of men (5 of 60) tested negative for PEth (p < 0.001). At the 3-month follow-up, 93% of women (25 of 27) and 97% of men (30 of 31) who reported drinking tested positive, while 70% of women (28 of 40) and 35% of men (10 of 29) who denied drinking tested negative for PEth. Interviews were consistent with self-reported alcohol use among 13 individuals with negative baseline results. CONCLUSIONS: These results add to the growing literature showing lack of agreement between self-report and PEth results among unhealthy and nondaily drinkers, particularly women. More research is needed to determine at what level of consumption over what period of time PEth becomes a reliable and accurate indicator of alcohol use.

RESUMO

OBJECTIVE: Efficient, effective health care requires rapid availability of patient information. We designed, implemented, and assessed the impact of a primary care electronic medical record (EMR) in three rural Kenyan health centers. METHOD: Local clinicians identified data required for primary care and public health reporting. We designed paper encounter forms to capture these data in adult medicine, pediatric, and antenatal clinics. Encounter form data were hand-entered into a new primary care module in an existing EMR serving onsite clinics serving patients infected with the human immunodeficiency virus (HIV). Before subsequent visits, Summary Reports were printed containing selected patient data with reminders for needed HIV care. We assessed effects on patient flow and provider work with time-motion studies before implementation and two years later, and we surveyed providers' satisfaction with the EMR. RESULTS: Between September 2008 and December 2011, 72 635 primary care patients were registered and 114 480 encounter forms were completed. During 2011, 32 193 unique patients visited primary care clinics, and encounter forms were completed for all visits. Of 1031 (3.2%) who were HIV-infected, 85% received HIV care. Patient clinic time increased from 37 to 81 min/visit after EMR implementation in one health center and 56 to 106 min/visit in the other. However, outpatient visits to both health centers increased by 85%. Three-quarters of increased time was spent waiting. Despite nearly doubling visits, there was no change in clinical officers' work patterns, but the nurses' and the clerks' patient care time decreased after EMR implementation. Providers were generally satisfied with the EMR but desired additional training. CONCLUSIONS: We successfully implemented a primary care EMR in three rural Kenyan health centers. Patient waiting time was dramatically lengthened while the nurses' and the clerks' patient care time decreased. Long-term use of EMRs in such settings will require changes in culture and workflow.

RESUMO

We evaluated performance, accuracy, and acceptability parameters of unsupervised oral fluid (OF) HIV self-testing (HIVST) in a general population in western Kenya. In a prospective validation design, we enrolled 240 adults to perform rapid OF HIVST and compared results to staff administered OF and rapid fingerstick tests. All reactive, discrepant, and a proportion of negative results were confirmed with lab ELISA. Twenty participants were video-recorded conducting self-testing. All participants completed a staff administered survey before and after HIVST to assess attitudes towards OF HIVST acceptability. HIV prevalence was 14.6 %. Thirty-six of the 239 HIVSTs were invalid (15.1 %; 95 % CI 11.1-20.1 %), with males twice as likely to have invalid results as females. HIVST sensitivity was 89.7 % (95 % CI 73-98 %) and specificity was 98 % (95 % CI 89-99 %). Although sensitivity was somewhat lower than expected, there is clear interest in, and high acceptability (94 %) of OF HIV self-testing.

RESUMO

BACKGROUND: Widespread violence followed the 2007 presidential elections in Kenya resulting in the deaths of a reported 1,133 people and the displacement of approximately 660,000 others. At the time of the crisis the United States Agency for International Development-Academic Model Providing Access to Healthcare (USAID-AMPATH) Partnership was operating 17 primary HIV clinics in western Kenya and treating 59,437 HIV positive patients (23,437 on antiretroviral therapy (ART)). METHODS: This case study examines AMPATH's provision of care and maintenance of patients on ART throughout the period of disruption. This was accomplished by implementing immediate interventions including rapid information dissemination through the media, emergency hotlines and community liaisons; organization of a Crisis Response leadership team; the prompt assembly of multidisciplinary teams to address patient care, including psychological support staff (in clinics and in camps for internally displaced persons (IDP)); and the use of the AMPATH Medical Records System to identify patients on ART who had missed clinic appointments. RESULTS: These interventions resulted in the opening of all AMPATH clinics within five days of their scheduled post-holiday opening dates, 23,949 patient visits in January 2008 (23,259 previously scheduled), uninterrupted availability of antiretrovirals at all clinics, treatment of 1,420 HIV patients in IDP camps, distribution of basic provisions, mobilization of outreach services to locate missing AMPATH patients and delivery of psychosocial support to 300 staff members and 632 patients in IDP camps. CONCLUSION: Key lessons learned in maintaining the delivery of HIV care in a crisis situation include the importance of advance planning to develop programs that can function during a crisis, an emphasis on a rapid programmatic response, the ability of clinics to function autonomously, patient knowledge of their disease, the use of community and patient networks, addressing staff needs and developing effective patient tracking systems.

RESUMO

In the context of a long-term institutional 'twinning' partnership initiated by Indiana and Moi Universities more than 22 years ago, a vibrant program of research has arisen and grown in size and stature. The history of the AMPATH (Academic Model Providing Access to Healthcare) Research Program is described, with its distinctive attention to Kenyan-North American equity, mutual benefit, policies that support research best practices, peer review within research working groups/cores, contributions to clinical care, use of healthcare informatics, development of research infrastructure and commitment to research workforce capacity. In the development and management of research within our partnership, we describe a number of significant challenges we have encountered that require ongoing attention, many of which are "good problems" occasioned by the program's success and growth. Finally, we assess the special value a partnership program like ours has created and end by affirming the importance of organizational diversity, solidarity of purpose, and resilience in the 'research enterprise.'

RESUMO

BACKGROUND: Measurement of adherence to antiretroviral therapy (ART) by patient self-report is common in resource-limited settings but widely believed to overstate actual adherence. The extent to which these measures overstate adherence has not been examined among a large patient population. METHODS: HIV-infected adult patients in Kenya who initiated ART within the past 3 months were followed for 6 months. Adherence was measured by participants' self-reports of doses missed in the past 7 days during monthly clinic visits and by continuous Medication Event Monitoring System (MEMS) in participants' pill bottles. Seven-day self-reported adherence was compared to 7-day MEMS adherence, 30-day MEMS adherence, and adherence more than 90% during each of the first 6 months. RESULTS: Self-reported and MEMS adherence measures were linked for 669 participants. Mean 7-day self-reported adherence was 98.7% and mean 7-day MEMS adherence was 86.0%, a difference of 12.7% (P < 0.01). The difference between the two adherence measures increased over time due to a decline in 7-day MEMS adherence. However, patients with lower MEMS adherence were in fact more likely to self-report missed doses and the difference between self-reported and MEMS adherence was similar for each number of self-reported missed doses. When analysis was limited to patients who reported rarely or never removing multiple doses at the same time, mean difference was 10.5% (P < 0.01). CONCLUSION: There is a sizable and significant difference between self-reported and MEMS adherence. However, a strong relationship between the measures suggests that self-reported adherence is informative for clinical monitoring and program evaluation.

RESUMO

Epidemics of both HIV/AIDS and alcohol abuse in sub-Saharan Africa have spurred the conduct of local behavioral therapy trials for these problems, but the ethical issues involved in these trials have not been fully examined. In this paper, we discuss ethical issues that emerged during the conduct of a behavioral intervention adaptation and trial using cognitive-behavioral therapy to reduce alcohol use among HIV-infected outpatients in Eldoret, Kenya. The study was performed within our multinational collaboration, the USAID-Academic Model Providing Access to Healthcare Partnership. We discuss relevant ethical considerations and how we addressed them.

RESUMO

Background. There was a 6-month shortage of antiretrovirals (cART) in Kenya. Methods. We assessed morbidity, mortality, and loss to follow-up (LTFU) in this retrospective analysis of adults who were enrolled during the six-month period with restricted cART (cap) or the six months prior (pre-cap) and eligible for cART at enrollment by the pre-cap standard. Cox models were used to adjust for potential confounders. Results. 9009 adults were eligible for analysis: 4,714 pre-cap and 4,295 during the cap. Median number of days from enrollment to cART initiation was 42 pre-cap and 56 for the cap (P < 0.001). After adjustment, individuals in the cap were at higher risk of mortality (HR = 1.21; 95% CI : 1.06-1.39) and LTFU (HR = 1.12; 95% CI : 1.04-1.22). There was no difference between the groups in their risk of developing a new AIDS-defining illness (HR = 0.92 95% CI 0.82-1.03). Conclusions. Rationing of cART, even for a relatively short period of six months, led to clinically adverse outcomes.

RESUMO

AIMS: Dual epidemics of human immunodeficiency virus (HIV) and alcohol use disorders, and a dearth of professional resources for behavioral treatment in sub-Saharan Africa, suggest the need for development of culturally relevant and feasible interventions. The purpose of this study was to test the preliminary efficacy of a culturally adapted six-session gender-stratified group cognitive-behavioral therapy (CBT) intervention delivered by paraprofessionals to reduce alcohol use among HIV-infected out-patients in Eldoret, Kenya. DESIGN: Randomized clinical trial comparing CBT against a usual care assessment-only control. SETTING: A large HIV out-patient clinic in Eldoret, Kenya, part of the Academic Model for Providing Access to Healthcare collaboration. PARTICIPANTS: Seventy-five HIV-infected out-patients who were antiretroviral (ARV)-initiated or ARV-eligible and who reported hazardous or binge drinking. MEASUREMENTS: Percentage of drinking days (PDD) and mean drinks per drinking days (DDD) measured continuously using the Time line Follow back method. FINDINGS: There were 299 ineligible and 102 eligible out-patients with 12 refusals. Effect sizes of the change in alcohol use since baseline between the two conditions at the 30-day follow-up were large [d=0.95, P=0.0002, mean difference=24.93, 95% confidence interval (CI): 12.43, 37.43 PDD; d=0.76, P=0.002, mean difference=2.88, 95% CI: 1.05, 4.70 DDD]. Randomized participants attended 93% of the six CBT sessions offered. Reported alcohol abstinence at the 90-day follow-up was 69% (CBT) and 38% (usual care). Paraprofessional counselors achieved independent ratings of adherence and competence equivalent to college-educated therapists in the United States. Treatment effect sizes were comparable to alcohol intervention studies conducted in the United States. CONCLUSIONS: Cognitive-behavioral therapy can be adapted successfully to group paraprofessional delivery in Kenya and may be effective in reducing alcohol use among HIV-infected Kenyan out-patients.

RESUMO

The baraza is a customary form of community assembly in East Africa. We examined the use of the health baraza as a process that can improve data collection and deepen community understanding of sociocultural issues surrounding HIV/AIDS. In the evaluation of the United States Agency for International Development (USAID)-Academic Model for Prevention and Treatment of HIV/AIDS Partnership (USAID-AMPATH) in Kenya, investigators facilitated mabaraza (the plural of baraza) to gather information of relevance to program success, improvement, and community collaboration. Seven mabaraza were held at local health facilities. Mabaraza rapidly evoked essential information for the USAID-AMPATH program and facilitated vibrant discussion of themes that were of interest to local communities. Mabaraza combined individual and community outlooks, producing emic understanding of the program's meaning to local populations. The baraza assemblage is a promising technique for applied sociology, participatory research, and program evaluation.

RESUMO

OBJECTIVE: To determine the incidence of loss to follow-up in a treatment programme for people living with human immunodeficiency virus (HIV) infection in Kenya and to investigate how loss to follow-up is affected by gender. METHODS: Between November 2001 and November 2007, 50 275 HIV-positive individuals aged ≥ 14 years (69% female; median age: 36.2 years) were enrolled in the study. An individual was lost to follow-up when absent from the HIV treatment clinic for > 3 months if on combination antiretroviral therapy (cART) or for > 6 months if not. The incidence of loss to follow-up was calculated using Kaplan-Meier methods and factors associated with loss to follow-up were identified by logistic and Cox multivariate regression analysis. FINDINGS: Overall, 8% of individuals attended no follow-up visits, and 54% of them were lost to follow-up. The overall incidence of loss to follow-up was 25.1 per 100 person-years. Among the 92% who attended at least one follow-up visit, the incidence of loss to follow-up before and after starting cART was 27.2 and 14.0 per 100 person-years, respectively. Baseline factors associated with loss to follow-up included younger age, a long travel time to the clinic, patient disclosure of positive HIV status, high CD4+ lymphocyte count, advanced-stage HIV disease, and rural clinic location. Men were at an increased risk overall and before and after starting cART. CONCLUSION: The risk of being lost to follow-up was high, particularly before starting cART. Men were more likely to become lost to follow-up, even after adjusting for baseline sociodemographic and clinical characteristics. Interventions designed for men and women separately could improve retention.

RESUMO

OBJECTIVES: To assess whether community-based care delivered by people living with HIV/AIDS (PLWAs) could replace clinic-based HIV care. DESIGN: Prospective cluster randomized controlled clinical trial. SETTING: Villages surrounding 1 rural clinic in western Kenya. SUBJECTS: HIV-infected adults clinically stable on antiretroviral therapy (ART). INTERVENTION: The intervention group received monthly Personal Digital Assistant supported home assessments by PLWAs with clinic appointments every 3 months. The control group received standard of care monthly clinic visits. MAIN OUTCOMES MEASURED: Viral load, CD4 count, Karnofsky score, stability of ART regimen, opportunistic infections, pregnancies, and number of clinic visits. RESULTS: After 1 year, there were no significant intervention-control differences with regard to detectable viral load, mean CD4 count, decline in Karnofsky score, change in ART regimen, new opportunistic infection, or pregnancy rate. Intervention patients made half as many clinic visits as did controls (P < 0.001). CONCLUSIONS: Community-based care by PLWAs resulted in similar clinical outcomes as usual care but with half the number of clinic visits. This pilot study suggests that task-shifting and mobile technologies can deliver safe and effective community-based care to PLWAs, expediting ART rollout and increasing access to treatment while expanding the capacity of health care institutions in resource-constrained environments.

RESUMO

Traditional homemade brew is believed to represent the highest proportion of alcohol use in sub-Saharan Africa. In Eldoret, Kenya, two types of brew are common: chang'aa, spirits, and busaa, maize beer. Local residents refer to the amount of brew consumed by the amount of money spent, suggesting a culturally relevant estimation method. The purposes of this study were to analyze ethanol content of chang'aa and busaa; and to compare two methods of alcohol estimation: use by cost, and use by volume, the latter the current international standard. Laboratory results showed mean ethanol content was 34% (SD = 14%) for chang'aa and 4% (SD = 1%) for busaa. Standard drink unit equivalents for chang'aa and busaa, respectively, were 2 and 1.3 (US) and 3.5 and 2.3 (Great Britain). Using a computational approach, both methods demonstrated comparable results. We conclude that cost estimation of alcohol content is more culturally relevant and does not differ in accuracy from the international standard.

RESUMO

Two-thirds of those with HIV worldwide live in sub-Saharan Africa. Alcohol use is associated with the HIV epidemic through risky sex and suboptimal ARV adherence. In western Kenya, hazardous drinking was reported by HIV (53%) and general medicine (68%) outpatients. Cognitive behavioral treatment (CBT) has demonstrated strong efficacy to reduce alcohol use. This article reports on a systematic cultural adaptation and pilot feasibility study of group paraprofessional-delivered CBT to reduce alcohol use among HIV-infected outpatients in Eldoret, Kenya. Following adaptation and counselor training, five pilot groups were run (n = 27). Overall attendance was 77%. Percent days abstinent from alcohol (PDA) before session 1 was 52-100% (women) and 21-36% (men), and by session 6 was 96-100% (women) and 89-100% (men). PDA effect sizes (Cohen's d) between first and last CBT session were 2.32 (women) and 2.64 (men). Participants reported treatment satisfaction. Results indicate feasibility, acceptability and preliminary efficacy for CBT in Kenya.
