Timely initiation of HIV antiretroviral therapy in Haiti 2004-2018: a retrospective cohort study.

OBJECTIVE: To describe trends in timing of ART initiation for newly diagnosed people living with HIV before and after Haiti adopted its Test and Start policy for universal HIV antiretroviral therapy (ART) in July 2016, and to explore predictors of timely ART initiation for both newly and previously diagnosed people living with HIV following Test and Start adoption. METHODS: This retrospective cohort study explored timing of ART initiation among 147 900 patients diagnosed with HIV at 94 ART clinics in 2004-2018 using secondary electronic medical record data. The study used survival analysis methods to assess time trends and risk factors for ART initiation. RESULTS: Timely uptake of ART expanded with Test and Start, such that same-day ART initiation rates increased from 3.7% to 45.0%. However, only 11.0% of previously diagnosed patients initiated ART after Test and Start. In adjusted analyses among newly diagnosed people living with HIV, factors negatively associated with timely ART initiation included being a pediatric patient aged 0-14 years (HR = 0.23, p < 0.001), being male (HR = 0.92, p = 0.03), being 50+ years (HR = 0.87, p = 0.03), being underweight (HR = 0.79, p < 0.001), and having WHO stage 3 (HR = 0.73, p < 0.001) or stage 4 disease (HR = 0.49, p < 0.001). Variation in timely ART initiation by geographic department and health facility was observed. CONCLUSIONS: Haiti has made substantial progress in scaling up Test and Start, but further work is needed to enroll previously diagnosed patients and to ensure rapid ART in key patient subgroups. Further research is needed on facility and geographic factors and on strategies for improving timely ART initiation among vulnerable subgroups.

[ABSTRACT]. Objective. To describe trends in timing of ART initiation for newly diagnosed people living with HIV before and after Haiti adopted its Test and Start policy for universal HIV antiretroviral therapy (ART) in July 2016, and to explore predictors of timely ART initiation for both newly and previously diagnosed people living with HIV following Test and Start adoption. Methods. This retrospective cohort study explored timing of ART initiation among 147 900 patients diagnosed with HIV at 94 ART clinics in 2004–2018 using secondary electronic medical record data. The study used survival analysis methods to assess time trends and risk factors for ART initiation. Results. Timely uptake of ART expanded with Test and Start, such that same-day ART initiation rates increased from 3.7% to 45.0%. However, only 11.0% of previously diagnosed patients initiated ART after Test and Start.

Haiti has made substantial progress in scaling up Test and Start, but further work is needed to enroll previously diagnosed patients and to ensure rapid ART in key patient subgroups. Further research is needed on facility and geographic factors and on strategies for improving timely ART initiation among vulnerable subgroups.

[RESUMO]. Objetivo. Descrever as tendências para o momento do início da terapia antirretroviral (TAR) em pessoas recém diagnosticadas vivendo com HIV antes de e após o Haiti adotar a política Testar e Tratar com a TAR universal para HIV, em julho de 2016, e analisar os preditores do início precoce da TAR em pessoas recém ou previamente diagnosticadas que vivem com HIV após a adoção da política Testar e Tratar. Métodos. Este estudo de coorte retrospectivo analisou o momento do início da TAR de 147 900 pacientes diagnosticados com HIV em 94 ambulatórios de TAR entre 2004 e 2018, usando dados de registros médicos eletrônicos secundários. O estudo usou métodos de análise de sobrevivência para avaliar as tendências temporais e os fatores de risco para o início da TAR. Resultados. A adoção precoce da TAR foi ampliada com a política Testar e Tratar de tal maneira que as taxas do início da TAR no mesmo dia do diagnóstico aumentaram de 3,7% para 45%. Porém, somente 11% dos pacientes previamente diagnosticados iniciaram a TAR após a política Testar e Tratar. Nas análises ajustadas entre as pessoas recém diagnosticadas vivendo com HIV, os fatores negativamente associados ao início precoce da TAR incluíram: ser paciente pediátrico de 0 a 14 anos de idade (HR = 0,23, p < 0,001), ser do sexo masculino (HR = 0,92, p = 0,03), ter 50 anos de idade ou mais (HR = 0,87, p = 0,03), ter peso inferior ao normal (HR = 0,79, p < 0.001) e estar na fase 3 da OMS (HR = 0,73, p < 0,001) ou fase 4 da doença (HR = 0,49, p < 0,001). Foi observada variação no início precoce da TAR por região geográfica e instituição de saúde. Conclusões. O Haiti obteve avanços substanciais na ampliação da política Testar e Tratar, mas é necessário mais trabalho para inscrever pacientes previamente diagnosticados e para assegurar a TAR rápida em subgrupos-chave de pacientes. Mais pesquisas são necessárias sobre fatores geográficos e de instituições de saúde e sobre estratégias para a melhoria do início precoce da TAR entre subgrupos vulneráveis.

[RESUMEN]. Objetivo. Describir las tendencias en cuanto al momento de iniciar el tratamiento antirretroviral (TAR) de personas con infección por el VIH recién diagnosticadas antes y después de julio del 2016, cuando Haití adoptó la política de prueba e inicio del tratamiento con el TAR universal contra el VIH, y explorar los factores predictivos del inicio oportuno del TAR en personas con infección por el VIH recién diagnosticada y diagnosticada con anterioridad después de la adopción de esta política. Métodos. En este estudio de cohortes retrospectivo se exploró el momento en que se inició el TAR en 147 900 pacientes con diagnóstico de infección por el VIH en 94 consultorios que administran TAR del 2004 al 2018 mediante datos secundarios de expedientes médicos electrónicos. El estudio empleó métodos de análisis de supervivencia para evaluar las tendencias temporales y los factores de riesgo del inicio del TAR. Resultados. La observancia oportuna del TAR se amplió con la política de prueba e inicio del tratamiento, de tal manera que el inicio del TAR en el mismo día aumentó de 3,7 % a 45,0 %. Sin embargo, solo 11,0 % de los pacientes anteriormente diagnosticados iniciaron el TAR tras la adopción de la política. En los análisis ajustados con personas con infección por el VIH recién diagnosticadas, los factores asociados negativamente con el inicio oportuno del TAR comprendían ser un paciente pediátrico entre 0 y 14 años de edad (HR = 0,23, p < 0,001), ser varón (HR = 0,92, p = 0,03), tener más de 50 años (HR = 0,87, p = 0,03), tener un peso bajo (HR = 0,79,p < 0.001) y estar en el estadio 3 (de HR = 0,73, p < 0,001) o en estadio 4 (HR = 0,49, p < 0,001) de la enfermedad según la OMS. Se consideró la variación en el inicio oportuno del TAR según departamento geográfico y establecimiento de salud. Conclusiones. Haití ha logrado avances considerables en la ampliación a mayor escala de la política de prueba e inicio del tratamiento, pero es necesario seguir trabajando para registrar a los pacientes diagnosticados con anterioridad y para asegurar el inicio rápido del TAR en los subgrupos de pacientes clave. Es preciso llevar a cabo investigaciones adicionales sobre los factores geográficos y los relacionados con los establecimientos y sobre las estrategias para mejorar el inicio oportuno del TAR en los subgrupos vulnerables.

Risk factors for delayed viral suppression on first-line antiretroviral therapy among persons living with HIV in Haiti, 2013-2017.

Studies of viral suppression on first-line antiretroviral therapy (ART) in persons living with human immunodeficiency virus (PLHIV) in Haiti are limited, particularly among PLHIV outside of the Ouest department, where the capital Port-au-Prince is located. This study described the prevalence and risk factors for delayed viral suppression among PLHIV in all geographic departments of Haiti between 2013 and 2017. Individuals who received viral load testing 3 to 12 months after ART initiation were included. Data on demographics and clinical care were obtained from the Haitian Active Longitudinal Tracking of HIV database. Multivariable logistic regression was performed to predict delayed viral suppression, defined as a viral load ≥1000 HIV-1 RNA copies/mL after at least 3 months on ART. Viral load test results were available for 3,368 PLHIV newly-initiated on ART. Prevalence of delayed viral suppression was 40%, which is slightly higher than previous estimates in Haiti. In the multivariable analysis, delayed viral suppression was significantly associated with younger age, receiving of care in the Ouest department, treatment with lamivudine (3TC), zidovudine (AZT), and nevirapine (NVP) combined ART regimen, and CD4 counts below 200 cells/mm3. In conclusion, this study was the first to describe and compare differences in delayed viral suppression among PLHIV by geographic department in Haiti. We identified populations to whom public health interventions, such as more frequent viral load testing, drug resistance testing, and ART adherence counseling should be targeted.

Impact of the 12 January 2010 earthquake on HIV case reporting in Haiti.

OBJECTIVE: To evaluate the impact of the 12 January 2010 earthquake on HIV cases from Haiti's national HIV surveillance system and assess the characteristics of people living with HIV 1-year before and after the earthquake. DESIGN: An interrupted time-series design and cross-sectional analysis. METHODS: We used autoregressive integrated moving average structures to model abrupt changes to the monthly, incident HIV case counts from HIV care clinics as reported to the Haitian Active Longitudinal Tracking of HIV System (French acronym SALVH) by clinical networks (n = 3) and earthquake instrumental intensity zones (n = 4). Preearthquake and postearthquake differences in patient-level characteristics including clinical values were examined using the χ test, t tests, Wilcoxon rank-sum test. RESULTS: In the month immediately following the earthquake, all three clinical networks experienced statistically significant declines in cases reported: iSanté (-31.4%), Groupe Haïtien d'Etude du Sarcome de Kaposi et des Infections Opportunistes (-29.9%) and Zamni Lasante (-32.2%). Zone 8 (the most severe) was the only area with a statistically significant decline (-45.5%). Of the three clinical networks, only iSanté returned to preearthquake reporting levels by the end of our study period. Patient-level characteristics did not change dramatically after the earthquake. CONCLUSION: Despite case reporting declines, especially in clinics near the earthquake epicenter, SALVH remained intact with less impact than expected. This national system is a critical component of Haiti's strategic health information system initiative and plays a central role to HIV monitoring and evaluation efforts.

Toward Universal HIV Treatment in Haiti: Time Trends in ART Retention After Expanded ART Eligibility in a National Cohort From 2011 to 2017.

BACKGROUND: The World Health Organization (WHO) recommends universal antiretroviral therapy (ART) for persons living with HIV (PLWH), but evidence about effects of expanded ART access on ART retention in low-resource settings is limited. SETTING: Haiti's Ministry of Health endorsed universal ART for pregnant women in March 2013 (Option B+) and for all PLWH in July 2016. This study included 51,579 ART patients from 2011 to 2017 at 94 hospitals and clinics in Haiti. METHODS: This observational, retrospective cohort study described time trends in 6-month ART retention using secondary data, and compared results during 3 periods using an interrupted time series model: pre-Option B+ (period 1: 1/11-2/13), Option B+ (period 2: 3/13-6/16), and Test and Start (T&S, period 3: 7/16-9/17). RESULTS: From the pre-Option B+ to the T&S period, the monthly count of new ART patients increased from 366/month to 877/month, and the proportion with same-day ART increased from 6.3% to 42.1% (P < 0.001). The proportion retained on ART after 6 months declined from 78.4% to 75.0% (P < 0.001). In the interrupted time series model, ART retention improved by a rate of 1.4% per quarter during the T&S period after adjusting for patient characteristics (adjusted incidence rate ratio = 1.014; 95% confidence interval: 1.002 to 1.026, P < 0.001). However, patients with same-day ART were 14% less likely to be retained compared to those starting ART >30 days after HIV diagnosis (adjusted incidence rate ratio = 0.86; 95% confidence interval: 0.84-0.89, P < 0.001). CONCLUSIONS: Achieving targets for HIV epidemic control will require increasing ART retention and reducing the disparity in retention for those with same-day ART.

Retention Throughout the HIV Care and Treatment Cascade: From Diagnosis to Antiretroviral Treatment of Adults and Children Living with HIV-Haiti, 1985-2015.

Monitoring retention of people living with HIV (PLHIV) in the HIV care and treatment cascade is essential to guide program strategy and evaluate progress toward globally-endorsed 90-90-90 targets (i.e., 90% of PLHIV diagnosed, 81% on sustained antiretroviral therapy (ART), and 73% virally suppressed). We describe national retention from diagnosis throughout the cascade for patients receiving HIV services in Haiti during 1985-2015, with a focus on those receiving HIV services during 2008-2015. Among the 266,256 newly diagnosed PLHIV during 1985-2015, 49% were linked-to-care, 30% started ART, and 18% were retained on ART by the time of database closure. Similarly, among the 192,187 newly diagnosed HIV-positive patients during 2008-2015, 50% were linked to care, 31% started ART, and 19% were retained on ART by the time of database closure. Most patients (90-92%) at all cascade steps were adults (≥ 15 years old), among whom the majority (60-61%) were female. During 2008-2015, outcomes varied significantly across 42 administrative districts (arrondissements) of residence; cumulative linkage-to-care ranged from 23% to 69%, cumulative ART initiation among care enrollees ranged from 2% to 80%, and cumulative ART retention among ART enrollees ranged from 30% to 88%. Compared with adults, children had lower cumulative incidence of ART initiation among care enrollees (64% versus 47%) and lower cumulative retention among ART enrollees (64% versus 50%). Cumulative linkage-to-care was low and should be prioritized for improvement. Variations in outcomes by arrondissement and between adults and children require further investigation and programmatic response.

Trends in Prevalence of Advanced HIV Disease at Antiretroviral Therapy Enrollment - 10 Countries, 2004-2015.

Monitoring prevalence of advanced human immunodeficiency virus (HIV) disease (i.e., CD4+ T-cell count <200 cells/µL) among persons starting antiretroviral therapy (ART) is important to understand ART program outcomes, inform HIV prevention strategy, and forecast need for adjunctive therapies.*,†,§ To assess trends in prevalence of advanced disease at ART initiation in 10 high-burden countries during 2004-2015, records of 694,138 ART enrollees aged ≥15 years from 797 ART facilities were analyzed. Availability of national electronic medical record systems allowed up-to-date evaluation of trends in Haiti (2004-2015), Mozambique (2004-2014), and Namibia (2004-2012), where prevalence of advanced disease at ART initiation declined from 75% to 34% (p<0.001), 73% to 37% (p<0.001), and 80% to 41% (p<0.001), respectively. Significant declines in prevalence of advanced disease during 2004-2011 were observed in Nigeria, Swaziland, Uganda, Vietnam, and Zimbabwe. The encouraging declines in prevalence of advanced disease at ART enrollment are likely due to scale-up of testing and treatment services and ART-eligibility guidelines encouraging earlier ART initiation. However, in 2015, approximately a third of new ART patients still initiated ART with advanced HIV disease. To reduce prevalence of advanced disease at ART initiation, adoption of World Health Organization (WHO)-recommended "treat-all" guidelines and strategies to facilitate earlier HIV testing and treatment are needed to reduce HIV-related mortality and HIV incidence.
