RESUMO

We examined the secondary effects of an antiretroviral therapy (ART) adherence intervention on information, motivation, and behavioral skills (IMB) and patient-provider communication (PPC). Data were from a sample of 116 patients enrolled in a quasi-experimental mixed-methods study at two large ART clinics in Haiti. We examined changes in IMB and PPC scores after the intervention and the association between baseline PPC and endline IMB.The intervention was associated with increased scores in information (ß = 0.89, 95% CI [0.07, 1.70]) and motivation (ß = 2.55, 95% CI [0.38, 4.72]) but a decreased score in behavioral skills (ß = -2.39, 95% CI [-4.29, -0.49]), after controlling for demographic and clinical variables. Baseline PPC was associated with higher endline IMB total scores (ß = 0.17, 95% CI [0.02, 0.31]), controlling for demographic variables, clinical variables, and baseline IMB score. At the subscale level, baseline PPC was associated with higher endline motivation score (ß = 0.09, 95% CI [0.01, 0.17]), marginally associated with higher endline information score (ß = 0.04, 95% CI [0.00, 0.08]), after controlling for demographic and clinical variables.The intervention was beneficial to patients' adherence related motivation. Favorable patient-provider communication is associated with more motivation to adhere to ART.

RESUMO

INTRODUCTION: Our study describes changes in HIV care service delivery and continuity of HIV antiretroviral therapy (ART) for people living with HIV (PLHIV) during the 8 weeks before and after diagnosis of the first coronavirus disease 2019 (COVID-19) cases in Haiti on March 19, 2020. METHODS: Using data from 96 out of 167 health facilities offering ART services, we compared four ART program indicators: (1) count of HIV visits; (2) proportion of ART dispenses in community-based settings (DAC); (3) proportion of multi-month dispensing of ART medications > 6 months (> 6 m MMD); and (4) proportion of timely ART refills. We used uncontrolled interrupted time series (ITS) models to estimate slope and level changes in each indicator with the arrival of COVID-19. RESULTS AND DISCUSSION: From week 1 to week 16, the average number of HIV visits fell from 121.5 to 92.5 visits, the proportion of DAC rose from 22.7% to 36.7%, the proportion of > 6 m MMD rose from 29.4% to 48.4%, and the proportion of timely ART refills fell from 51.9% to 43.8%. The ITS models estimated abrupt increases of 36% in > 6 m MMD (p < 0.001) and 37% in DAC (p < 0.001) at the time of COVID-19 arrival, and no change after arrival of COVID-19. The was an abrupt decline of 18% in timely ART refills with the arrival of COVID-19 and a decline of 1% per week thereafter, both non-statistically significant changes. CONCLUSIONS: The sudden changes in HIV service utilization represent dramatic adaptations needed to mitigate primary and secondary effects of the COVID-19 pandemic on PLHIV. This study underscores the urgency of optimizing ART delivery models in Haiti and beyond, in order to maintain progress toward HIV epidemic control.

RESUMO

To promote HIV antiretroviral therapy (ART) outcomes in Haiti, we developed a culturally relevant intervention (InfoPlus Adherence) that combines an electronic medical record alert identifying patients at elevated risk of treatment failure and provider-delivered brief problem-solving counseling. We conducted a quasi-experimental mixed-methods study among 146 patients at two large ART clinics in Haiti with 728 historical controls. We conducted quantitative assessments of patients at baseline and intervention completion (6 months) as well as focus groups with health workers and exit interviews with patients. The primary quantitative outcome measures were HIV viral suppression according to medical record and ART adherence in terms of ≥ 90% for "proportion of days covered" (PDC) according to pharmacy dispensing data. Results indicated that the proportion of intervention patients with suppressed VL during the study/historical periods was 80.0%/86.0% and 76.8%/87.4% for controls. In a difference-in-differences (DID) analytic model, the adjusted relative risk for viral suppression with the intervention was 1.15 (95% CI 0.92-1.45, p = 0.21), representing favorable but non-significant association between the intervention and the trajectory of VL outcomes. PDC ≥ 90% during the study/historical periods was 30.9%/11.0% among intervention participants and 16.9%/19.4% among controls. In the adjusted DID model, the relative risk for of PDC ≥ 90% with the intervention was 4.00 (95% CI 1.91-8.38, p < 0.001), representing a highly favorable association between the intervention and the trajectory of PDC outcomes. Qualitative data affirmed acceptability of the intervention, although providers reported some challenges consistently implementing it. Future research is needed to demonstrate efficacy and explore optimal implementation strategies.

RESUMO

BACKGROUND: Haiti initiated the scale-up of HIV viral load (VL) testing in 2015-2016, with plans to achieve 100% coverage for all patients on antiretroviral therapy (ART) for treatment of HIV/AIDS. In the absence of HIV drug susceptibility testing, VL testing is a key tool for monitoring response to ART and optimizing treatment results. This study describes trends in expanded use of VL testing, VL results, and use of second-line ART regimens, and explores the association between VL testing and second-line regimen switching in Haiti from 2010 to 2017. METHODS: We conducted a retrospective cohort study with 66,042 patients drawn from 88 of Haiti's 160 national ART clinics. Longitudinal data from the iSanté electronic data system was used to analyze the trends of interest. We described patients' VL testing status in five categories based on up to two most recent VL test results: no test; suppressed; unsuppressed followed by no test; re-suppressed; and confirmed failure. Among those with confirmed failure, we described ART adherence level. Finally, we used Cox proportional hazards regression to estimate the risk of second-line regimen switching by VL testing status, after adjusting for other individual characteristics. RESULTS: The number of patients who had tests done increased annually from 11 in 2010 to 18,828 in the first 9 months of 2017, while the number of second-line regimen switches rose from 21 to 279 during this same period. Compared with patients with no VL test, the hazard ratio (HR) for switching to a second-line regimen was 22.2 for patients with confirmed VL failure (95% confidence interval [CI] for HR: 18.8-26.3; p < 0.005) after adjustment for individual characteristics. Among patients with confirmed VL failure, 44.7% had strong adherence, and fewer than 20% of patients switched to a second-line regimen within 365 days of VL failure. CONCLUSIONS: Haiti has significantly expanded access to VL testing since 2016. In order to promote optimal patient health outcomes, it is essential for Haiti to continue broadening access to confirmatory VL testing, to expand evidence-based initiatives to promote strong ART adherence, and to embrace timely switching for patients with confirmed ART failure despite strong ART adherence.

RESUMO

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

RESUMO

While Haiti has scaled up use of antiretroviral therapy (ART), current studies suggest sub-optimal adherence threatens long-term viral suppression in this understudied setting. Patient-provider communication (PPC) and information, motivation, and behavioral skills (IMB) have been implicated in ART adherence globally. However, no studies have examined their relevance in Haiti. The present mixed-methods study utilized cross-sectional survey data from 128 ART-initiating patients at 2 large HIV treatment sites in Haiti, as well as observational data from 12 clinic visits, to document associations between adherence-related PPC and IMB. Multivariate regression analyses suggested that PPC is associated with IMB constructs. At the bivariate level, more effective PPC was associated with higher levels of adherence-related information and motivation, but not behavioral skills. Observational findings indicate infrequent and non-collaborative adherence support. Taken together, findings lay the groundwork for additional research in the area of PPC, IMB, and ART adherence in Haiti.

RESUMO

HIV self-testing (HIVST), which allows people to test in private, is an innovative testing strategy that has been shown to increase HIV testing among men. Delivering HIVST kits to men via women is one promising assisted partner service strategy. Little research has been conducted on HIVST secondary distribution to men by women living with HIV (WLWH) in the Caribbean and other settings. The purpose of this study was to assess the perspectives of WLWH, their male partners, and healthcare professionals on the perceived advantages and disadvantages of HIVST, and recommendations for implementing HIVST in Haiti, with a focus on secondary distribution of HIVST to men by WLWH. Sixteen key informant interviews and nine focus groups with 44 healthcare workers, 31 Option B+ clients, and 13 men were carried out in Haiti. Key informants were representatives of the Ministry of Health and of a non-governmental agency involved in HIV partner services. Focus group members included program leads and staff members from the HIV care and treatment program, the Option B+ program, the community health service program, and the HIV counseling and testing services from 2 hospitals. Perceived HIVST advantage included an increase in the number of people who would learn their HIV status and start treatment. The perceived disadvantages were lack of support to ensure self-testers initiate treatment, uncertainty about male partner's reaction, risk of violence towards women delivering HIVST kits after receiving an HIVST kit from a woman, and the inability of women to counsel a man in case his self-test result is positive. Recommendations for integrating HIVST and secondary distribution of HIVST by WLWH included coupling HIVST distribution with public information, education, and communication through media and social marketing, relying on community health workers to mediate use of HIVST and ensure linkage to care, piloting HIVST programs on a small scale. HIVST is an appropriate and feasible strategy HIV prevention for men and women; however, more research is needed on how best to implement different strategies for this approach in the Caribbean.

RESUMO

BACKGROUND: The adoption of electronic medical record systems in resource-limited settings can help clinicians monitor patients' adherence to HIV antiretroviral therapy (ART) and identify patients at risk of future ART failure, allowing resources to be targeted to those most at risk. METHODS: Among adult patients enrolled on ART from 2005-2013 at two large, public-sector hospitals in Haiti, ART failure was assessed after 6-12 months on treatment, based on the World Health Organization's immunologic and clinical criteria. We identified models for predicting ART failure based on ART adherence measures and other patient characteristics. We assessed performance of candidate models using area under the receiver operating curve, and validated results using a randomly-split data sample. The selected prediction model was used to generate a risk score, and its ability to differentiate ART failure risk over a 42-month follow-up period was tested using stratified Kaplan Meier survival curves. RESULTS: Among 923 patients with CD4 results available during the period 6-12 months after ART initiation, 196 (21.2%) met ART failure criteria. The pharmacy-based proportion of days covered (PDC) measure performed best among five possible ART adherence measures at predicting ART failure. Average PDC during the first 6 months on ART was 79.0% among cases of ART failure and 88.6% among cases of non-failure (p<0.01). When additional information including sex, baseline CD4, and duration of enrollment in HIV care prior to ART initiation were added to PDC, the risk score differentiated between those who did and did not meet failure criteria over 42 months following ART initiation. CONCLUSIONS: Pharmacy data are most useful for new ART adherence alerts within iSanté. Such alerts offer potential to help clinicians identify patients at high risk of ART failure so that they can be targeted with adherence support interventions, before ART failure occurs.

RESUMO

BACKGROUND: On January 12, 2010, a devastating 7.0 magnitude earthquake struck the West Department of Haiti, killing more than 200,000 people and injuring or displacing many more. This disaster threatened continuity of HIV care and treatment services. OBJECTIVES: This case study examined the effect of the devastating 2010 earthquake in Haiti on attrition from the HIV antiretroviral therapy (ART) program. DESIGN: The study triangulated retrospective data from existing sources, including: 1) individual-level longitudinal patient data from an electronic medical record for ART patients at two large public sector departmental hospitals differently affected by the earthquake; and 2) aggregate data on the volume of HIV-related services delivered at the two hospitals before and after the earthquake. METHODS: The study compared ART attrition and service delivery in Jacmel, a site in the 'very strong' zone of earthquake impact, and in Jérémie, a site in the 'light' zone of earthquake impact. The analysis used time-to-event analysis methods for the individual-level patient data, and descriptive statistical methods for the aggregate service delivery data. RESULTS: Adjusted ART attrition risk was lower at the hospital in Jacmel after vs. before the earthquake (HR=0.51; p=0.03), and was lower in Jacmel vs. Jérémie both before (HR=0.55; p=0.01) and after the earthquake (HR=0.35; p=0.001). The number of new ART patient enrollments, new HIV patient registrations, and HIV clinical visits dropped notably in Jacmel immediately after the earthquake, but then rapidly rebounded. On average, there was no change in new ART enrollments per month after vs. before the earthquake at either site. CONCLUSION: These findings underscore the resilience of Haitian ART providers and patients, and contribute evidence that it is possible to maintain continuity of ART services even in the context of a complex humanitarian crisis.
