High levels of HIV-1 drug resistance in children who acquired HIV infection through mother to child transmission in the era of Option B+, Haiti, 2013-2014
Louis FJ , Segaren N , Desinor O , Beard RS , Jean-Louis R , Chang J , Boisson S , Hulland EN , Wagar N , DeVos J , Francois K , Buteau J , Boncy J , Marston BJ , Domercant JW , Yang C , Charles M . Pediatr Infect Dis J 2018 38 (5) 503-507 BACKGROUND: The main objective of this study was to determine the frequency and patterns of HIVDR-associated mutations among children <18 months old born to HIV-1-positive mothers enrolled in the prevention of mother-to-child transmission (PMTCT) services in Haiti. METHODS: Between January 1, 2013 and December 31, 2014, HIV-positive remnant dried blood spots (DBS) collected from children under 18 months old for Early Infant Diagnosis (EID) at the National Public Health Laboratory were used for HIV-1 genotyping. HIVDR mutations were analyzed using the Stanford Drug Resistance HIVdb program. RESULTS: Of the 3,555 DBS collected for EID, 360 (10.1%) were HIV-positive and 355 were available for genotyping. Of these, 304 (85.6%) were successfully genotyped and 217 (71.4%) had >/= one DR mutation. Mutations conferring resistance to NRTIs and NNRTIs were present in 40.5% (123) and 69.1% (210), respectively. The most frequent mutations were K103N/S (48.0%), M184V (37.5%), and G190A/S (15.1%), and Y181C/G/V (14.1%). Predicted drug resistance analysis revealed that 68.8% of the children had high-level resistance to NNRTIs and 11.5% had intermediate to high-level resistance to abacavir. CONCLUSIONS: This study showed high rates of resistance to NRTIs and NNRTIs among newly HIV-diagnosed children in Haiti, suggesting that in the era of "option B+" (initiation of lifelong combination antiretroviral therapy to pregnant women with HIV), the majority of children who acquire HIV infection through MTCT have resistant HIV. These results have led the National HIV Program to revise the pediatric guidelines to include protease inhibitors in first-line regimens for all HIV-positive newborns. |

Jean Louis F , Buteau J , Francois K , Hulland E , Domercant JW , Yang C , Boncy J , Burris R , Pelletier V , Wagar N , Deyde V , Lowrance DW , Charles M . PLoS One 2018 13 (1) e0192077 INTRODUCTION: Viral load (VL) assessment is the preferred method for diagnosing and confirming virologic failure for patients on antiretroviral therapy (ART). We conducted a retrospective cross-sectional study to evaluate the virologic suppression rate among patients on ART for >/=6 months in five hospitals around Port-au-Prince, Haiti. METHODS: Plasma VL was measured and patients with VL <1,000 copies/mL were defined as virologically suppressed. A second VL test was performed within at least six months of the first test. Factors associated with virologic suppression were analyzed using logistic regression models accounting for site-level clustering using complex survey procedures. RESULTS: Data were analyzed for 2,313 patients on ART for six months or longer between July 2013 and February 2015. Among them, 1,563 (67.6%) achieved virologic suppression at the first VL test. A second VL test was performed within at least six months for 718 (31.0%) of the patients. Of the 459 patients with an initial HIV-1 RNA <1,000 copies/mL who had a second VL performed, 394 (85.8%) maintained virologic suppression. Virologic suppression was negatively associated with male gender (adjusted odds ratio [aOR]: 0.80, 95% CI: 0.74-0.0.86), 23 to 35 months on ART (aOR:0.72[0.54-0.96]), baseline CD4 counts of 201-500 cells/mm3 and 200 cells/mm3 or lower (aORs: 0.77 [0.62-0.95] and 0.80 [0.66-0.98], respectively), poor adherence (aOR: 0.69 [0.59-0.81]), and TB co-infection (aOR: 0.73 [0.55-0.97]). CONCLUSIONS: This study showed that over two-thirds of the patients in this evaluation achieved virologic suppression after >/= six months on ART and the majority of them remained suppressed. These results reinforce the importance of expanding access to HIV-1 viral load testing in Haiti for monitoring ART outcomes. |
The experience of violence against children in domestic servitude in Haiti: Results from the Violence Against Children Survey, Haiti 2012
Gilbert L , Reza A , Mercy J , Lea V , Lee J , Xu L , Marcelin LH , Hast M , Vertefeuille J , Domercant JW . Child Abuse Negl 2017 76 184-193 BACKGROUND: There have been estimates that over 150,000 Haitian children are living in servitude. Child domestic servants who perform unpaid labor are referred to as "restaveks." Restaveks are often stigmatized, prohibited from attending school, and isolated from family placing them at higher risk for experiencing violence. In the absence of national data on the experiences of restaveks in Haiti, the study objective was to describe the sociodemographic characteristics of restaveks in Haiti and to assess their experiences of violence in childhood. METHODS: The Violence Against Children Survey was a nationally representative, cross-sectional household survey of 13-24year olds (n=2916) conducted May-June 2012 in Haiti. A stratified three-stage cluster design was used to sample households and camps containing persons displaced by the 2010 earthquake. Respondents were interviewed to assess lifetime prevalence of physical, emotional, and sexual violence occurring before age 18. Chi-squared tests were used to assess the association between having been a restavek and experiencing violence in childhood. FINDINGS: In this study 17.4% of females and 12.2% of males reported having been restaveks before age 18. Restaveks were more likely to have worked in childhood, have never attended school, and to have come from a household that did not have enough money for food in childhood. Females who had been restaveks in childhood had higher odds of reporting childhood physical (OR 2.04 [1.40-2.97]); emotional (OR 2.41 [1.80-3.23]); and sexual violence (OR 1.86 [95% CI 1.34-2.58]) compared to females who had never been restaveks. Similarly, males who had ever been restaveks in childhood had significantly increased odds of emotional violence (OR 3.06 [1.99-4.70]) and sexual violence (OR 1.85 [1.12-3.07]) compared to males who had never been restaveks, but there was no difference in childhood physical violence. INTERPRETATION: This study demonstrates that child domestic servants in Haiti experience higher rates of childhood violence and have less access to education and financial resources than other Haitian children. These findings highlight the importance of addressing both the lack of human rights law enforcement and the poor economic circumstances that allow the practice of restavek to continue in Haiti. |
Retention throughout the HIV care and treatment cascade: from diagnosis to antiretroviral treatment of adults and children living with HIV-Haiti, 1985-2015
Auld AF , Valerie Pelletier , Robin EG , Shiraishi RW , Dee J , Antoine M , Desir Y , Desforges G , Delcher C , Duval N , Joseph N , Francois K , Griswold M , Domercant JW , Patrice Joseph YA , Van Onacker JD , Deyde V , Lowrance DW , The Groupe d'Analyses Salvh . Am J Trop Med Hyg 2017 97 57-70 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. |
Seroprevalence of herpes simplex virus type-2 (HSV-2) among pregnant women who participated in a national HIV surveillance activity in Haiti
Domercant JW , Jean Louis F , Hulland E , Griswold M , Andre-Alboth J , Ye T , Marston BJ . BMC Infect Dis 2017 17 (1) 577 BACKGROUND: Herpes simplex virus type 2 (HSV-2), one the most common causes of genital ulcers, appears to increase both the risk of HIV acquisition and HIV transmission. HSV-2/HIV co-infection among pregnant women may increase the risk of perinatal transmission of HIV. This study describes rates of HSV-2 among pregnant women in Haiti and HSV-2 test performance in this population. METHODS: Unlinked residual serum specimens from the 2012 National HIV and Syphilis Sentinel Surveillance Survey among pregnant women in Haiti were tested using two commercial kits (Focus HerpeSelect, Kalon) for HSV-2 antibodies. We evaluated rates of HSV-2 seropositivity and HSV-2/HIV co-infection, associations between HSV-2 and demographic characteristics using multivariable Cox proportional hazards modeling, and HSV-2 test performance in this population. RESULTS: Serum samples from 1000 pregnant women (all 164 HIV positive and 836 random HIV negative) were selected. The overall weighted prevalence of HSV-2 was 31.4% (95% CI: 27.7-35.4) and the prevalence of HIV-positivity among HSV-2 positive pregnant women was five times higher than the prevalence among HSV-2 negative women (4.8% [95% CI: 3.9-6.0] vs. 0.9% [95% CI: 0.6-1.3], respectively). Factors significantly associated with HSV-2 positivity were HIV-positivity (PR: 2.27 [95% CI: 1.94-2.65]) and older age (PRs: 1.41 [95% CI: 1.05-1.91] for 20-24 years, 1.71 [95% CI:1.13-2.60] for 30-34 years, and 1.55 [95% CI: 1.10-2.19] for 35 years or greater]), while rural residence was negatively associated with HSV-2 positivity (PR 0.83 [95% CI: 0.69-1.00]), after controlling for other covariables. For this study a conservative Focus index cutoff of 3.5 was used, but among samples with a Focus index value ≥2.5, 98.4% had positive Kalon tests. CONCLUSION: The prevalence of HSV-2 is relatively high among pregnant women in Haiti. Public health interventions to increase access to HSV-2 screening in antenatal services are warranted. |
Attrition from antiretroviral treatment services among pregnant and non-pregnant patients following adoption of Option B+ in Haiti
Domercant JW , Puttkammer N , Young P , Yuhas K , Francois K , Grand'Pierre R , Lowrance D , Adler M . Glob Health Action 2017 10 (1) 1330915 BACKGROUND: Access to antiretroviral therapy (ART) has expanded in Haiti because of the adoption of Option B+ and the revision of treatment guidelines. Retention in care and treatment varies greatly and few studies have examined retention rates, particularly among women enrolled in Option B+. OBJECTIVE: To assess attrition among pregnant and non-pregnant patients initiating ART following adoption of Option B+ in Haiti. METHODS: Longitudinal data of adult patients initiated on ART from October 2012 through August 2014 at 73 health facilities across Haiti were analyzed using a survival analysis framework to determine levels of attrition. The Kaplan-Meier method and Cox proportional hazards regression were used to examine risk factors associated with attrition. RESULTS: Among 17,059 patients who initiated ART, 7627 (44.7%) were non-pregnant women, 5899 (34.6%) were men, and 3533 (20.7%) were Option B+ clients. Attrition from the ART program was 36.7% at 12 months (95% CI: 35.9-37.5%). Option B+ patients had the highest level of attrition at 50.4% at 12 months (95% CI: 48.6-52.3%). While early HIV disease stage at ART initiation was protective among non-pregnant women and men, it was a strong risk factor among Option B+ clients. In adjusted analyses, key protective factors were older age (p < 0.0001), living near the health facility (p = 0.04), having another known HIV-positive household member (p < 0.0001), having greater body mass index (BMI) (p < 0.0001), pre-ART counseling (p < 0.0001), and Cotrimoxazole prophylaxis during baseline (p < 0.01). Higher attrition was associated with rapidly starting ART after enrollment (p < 0.0001), anemia (p < 0.0001), and regimen tenofovir+lamivudine+nevirapine (TDF+3TC+NVP) (p < 0.001). CONCLUSIONS: ART attrition in Haiti is high among adults, especially among Option B+ patients. Identifying newly initiated patients most at risk for attrition and providing appropriate interventions could help reduce ART attrition. |

MMWR Morb Mortal Wkly Rep 2017 66 (21) 558-563 Monitoring prevalence of advanced human immunodeficiency virus (HIV) disease (i.e., CD4+ T-cell count <200 cells/muL) among persons starting antiretroviral therapy (ART) is important to understand ART program outcomes, inform HIV prevention strategy, and forecast need for adjunctive therapies.*,dagger, section sign 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. |

McNairy ML , Joseph P , Unterbrink M , Galbaud S , Mathon JE , Rivera V , Jannat-Khah D , Reif L , Koenig SP , Domercant JW , Johnson W , Fitzgerald DW , Pape JW . PLoS One 2017 12 (4) e0175521 BACKGROUND: We report patient outcomes after antiretroviral therapy (ART) initiation in a network of HIV facilities in Haiti, including temporal trends and differences across clinics, during the expansion of HIV services in the country. METHODS: We assessed outcomes at 12 months after ART initiation (baseline) using routinely collected data on adults (≥15 years) in 11 HIV facilities from July 2007-December 2013. Outcomes include death (ascertained from medical records), lost to follow-up (LTF) defined as no visit > 365 days from ART initiation, and retention defined as being alive and attending care ≥ 365 days from ART initiation. Outcomes were compared across calendar year of ART initiation and across facilities. Risk factors for death and LTF were assessed using Cox proportional hazards and competing risk regression models. RESULTS: Cumulatively, 9,718 adults initiated ART with median age 37 years (IQR 30-46). Median CD4 count was 254 cells/uL (IQR 139-350). Twelve months after ART initiation, 4.4% (95% CI 4.0-4.8) of patients died, 21.7% (95% CI 20.9-22.6) were LTF, and 73.9% (95% CI 73.0-74.8) were retained in care. Twelve-month mortality decreased from 13.8% among adults who started ART in 2007 to 4.4% in 2013 (p<0.001). Twelve-month LTF after ART start was 29.2% in 2007, 18.7% in 2008, and increased to 30.1% in 2013 (p<0.001). Overall, twelve-month retention after ART start did not change over time but varied widely across facilities from 61.1% to 86.5%. CONCLUSION: Expansion of HIV services across Haiti has been successful with increasing numbers of patients initiating ART and decreasing twelve-month mortality rates. However, overall retention has not improved, despite differences across facilities, suggesting additional strategies to improve engagement in care are needed. |
ART attrition and risk factors among Option B+ patients in Haiti: A retrospective cohort study
Puttkammer N , Domercant JW , Adler M , Yuhas K , Myrtil M , Young P , Francois K , Grand'Pierre R , Lowrance D . PLoS One 2017 12 (3) e0173123 OBJECTIVES: In October 2012, the Haitian Ministry of Health endorsed the "Option B+" strategy to eliminate mother-to-child transmission of HIV and achieve HIV epidemic control. The objective of this paper is to assess and identify risk factors for attrition from the national ART program among Option B+ patients in the 12 months after ART initiation. DESIGN: This retrospective cohort study included patients newly initiating ART from October 2012-August 2013 at 68 ART sites covering 45% of all newly enrolled ART patients in all regions of Haiti. METHODS: With data from electronic medical records, we carried out descriptive analysis of sociodemographic, clinical, and pregnancy-related correlates of ART attrition, and used a modified Poisson regression approach to estimate relative risks in a multivariable model. RESULTS: There were 2,166 Option B+ patients who initiated ART, of whom 1,023 were not retained by 12 months (47.2%). One quarter (25.3%) dropped out within 3 months of ART initiation. Protective factors included older age, more advanced HIV disease progression, and any adherence counseling prior to ART initiation, while risk factors included starting ART late in gestation, starting ART within 7 days of HIV testing, and using an atypical ART regimen. DISCUSSION: Our study demonstrates early ART attrition among Option B+ patients and contributes evidence on the characteristics of women who are most at risk of attrition in Haiti. Our findings highlight the importance of targeted strategies to support retention among Option B+ patients. |
Low prevalence of cryptococcal antigenemia among patients infected with HIV/AIDS in Haiti
Louis FJ , Andre JA , Perrin G , Domercant JW , Francois K , Azor D , Buteau J , Boncy J , Burris R , Lowrance DW , Marston BJ . J AIDS Clin Res 2016 7 (6) 577 Cryptococcal meningitis is a common opportunistic infection among persons with advanced HIV-associated immunosuppression and is associated with high mortality. The prevalence of asymptomatic cryptococcal antigenemia (CrAg) can inform the potential utility of screening and pre-emptive treatment prevention strategies. We assessed CrAg prevalence in a cohort of patients infected with HIV at 28 health facilities from February to September 2014 in order to inform Haitian national clinical guidelines. Of 13,000 patients that underwent CD4 cell count, 1,025 (7.9%) had a count <=200 cells/mm3. Of these, 11 (1.1%) were CrAg positive. The CrAg positivity rate among patients with CD4 cell counts <100 cell/mm3 was 1.8%. Patients with CD4 cell counts <50 cells/mm3 had the highest CrAg rate (2.3%). CrAg prevalence was low but still warranted a CrAg screening and pre-emptive therapy approach for people infected with HIV with CD4 cell counts <100 cell/mm3 in Haiti. |
Hepatitis B virus infection among pregnant women in Haiti: A cross-sectional serosurvey
Tohme RA , Andre-Alboth J , Tejada-Strop A , Shi R , Boncy J , Francois J , Domercant JW , Griswold M , Hyppolite E , Adrien P , Kamili S . J Clin Virol 2016 76 66-71 BACKGROUND: Hepatitis B vaccine administered shortly after birth is highly effective in preventing mother to child transmission (MTCT) of infection. While hepatitis B vaccine was introduced in Haiti as part of a combined pentavalent vaccine in 2012, a birth dose is not yet included in the immunization schedule. OBJECTIVES: Determine the seroprevalence of hepatitis B virus (HBV) infection among pregnant women to evaluate the risk of MTCT. STUDY DESIGN: We selected 1364 residual serum specimens collected during a 2012 human immunodeficiency virus (HIV) sentinel serosurvey among pregnant women attending antenatal care clinics. Haiti was stratified into two regions: West, which includes metropolitan Port-au-Prince, and non-West, which includes all other departments. We evaluated the association between demographic and socioeconomic characteristics and HIV infection with HBV infection. RESULTS: Of 1364 selected specimens, 1307 (96%) were available for testing. A total of 422 specimens (32.7%) tested positive for total anti-HBc (38.2% in West vs. 27% in non-West, p<0.001), and 33 specimens (2.5%) were HBsAg positive (2.1% in West vs. 3% in non-West, p=0.4). Of HBsAg positive specimens, 79% had detectable HBV DNA. Women aged 30 and older had more than double the odds of positive total anti-HBc than women aged 15-19 years (p<0.001). Women with secondary (adjusted odds ratio (aOR)=0.54; 95% CI: 0.36-0.81) and post-secondary education (aOR=0.40, 95% CI: 0.19-0.79) had lower odds of total anti-HBc positivity compared with women with no education. HIV-status was not associated with HBV infection. CONCLUSIONS: Haiti has an intermediate endemicity of chronic HBV infection with high prevalence of positive HBV DNA among chronically infected women. Introduction of a universal birth dose of hepatitis B vaccine might help prevent perinatal HBV transmission. |
Specimen Referral Network to Rapidly Scale-Up CD4 Testing: The Hub and Spoke Model for Haiti
Louis FJ , Osborne AJ , Elias VJ , Buteau J , Boncy J , Elong A , Dismer A , Sasi V , Domercant JW , Lauture D , Balajee SA , Marston BJ . J AIDS Clin Res 2015 6 (8) OBJECTIVES: Regular and quality CD4 testing is essential to monitor disease progression in people living with HIV. In Haiti, most laboratories have limited infrastructure and financial resources and have relied on manual laboratory techniques. We report the successful implementation of a national specimen referral network to rapidly increase patient coverage with quality CD4 testing while at the same time building infrastructure for referral of additional sample types over time. METHOD: Following a thorough baseline analysis of facilities, expected workload, patient volumes, cost of technology and infrastructure constraints at health institutions providing care to HIV patients, the Haitian National Public Health Laboratory designed and implemented a national specimen referral network. The specimen referral network was scaled up in a step-wise manner from July 2011 to July 2014. RESULTS: Fourteen hubs serving a total of 67 healthcare facilities have been launched; in addition, 10 healthcare facilities operate FACSCount machines, 21 laboratories operate PIMA machines, and 11 healthcare facilities are still using manual CD4 tests. The number of health institutions able to access automated CD4 testing has increased from 27 to 113 (315%). Testing volume increased 76% on average. The number of patients enrolled on ART at the first healthcare facilities to join the network increased 182% within 6 months following linkage to the network. Performance on external quality assessment was acceptable at all 14 hubs. CONCLUSION: A specimen referral network has enabled rapid uptake of quality CD4 testing, and served as a backbone to allow for other future tests to be scaled-up in a similar way. |
Update on progress in selected public health programs after the 2010 earthquake and cholera epidemic - Haiti, 2014
Domercant JW , Guillaume FD , Marston BJ , Lowrance DW . MMWR Morb Mortal Wkly Rep 2015 64 (6) 137-40 On January 12, 2010, an earthquake devastated Haiti's infrastructure, killing an estimated 230,000 persons and displacing more than 1.5 million. Ten months later, Haiti experienced the beginning of the largest cholera epidemic ever reported in a single country. Immediately after the earthquake and at the start of the cholera epidemic, health priorities in Haiti included improvement of surveillance and laboratory capacity for addressing public health threats in the general population and targeted surveillance and provision of improved water and sanitation in camps for internally displaced persons. As part of a multi-sector, post-earthquake response in collaboration with the Government of Haiti and others, CDC focused on supporting the recovery, expansion, or establishment of several key health programs. This update reports progress in selected health programs, services, and systems in Haiti as of the end of 2014. |

Puttkammer NH , Zeliadt SB , Baseman JG , Destine R , Domercant JW , Coq NR , Raphael NA , Sherr K , Tegger M , Yuhas K , Barnhart S . Rev Panam Salud Publica 2014 36 (4) 238-47 OBJECTIVE: To identify factors associated with antiretroviral therapy (ART) attrition among patients initiating therapy in 2005-2011 at two large, public-sector department-level hospitals, and to inform interventions to improve ART retention. METHODS: This retrospective cohort study used data from the iSante electronic medical record (EMR) system. The study characterized ART attrition levels and explored the patient demographic, clinical, temporal, and service utilization factors associated with ART attrition, using time-to-event analysis methods. RESULTS: Among the 2 023 patients in the study, ART attrition on average was 17.0 per 100 person-years (95% confidence interval (CI): 15.8-18.3). In adjusted analyses, risk of ART attrition was up to 89% higher for patients living in distant communes compared to patients living in the same commune as the hospital (hazard ratio: 1.89, 95%CI: 1.54-2.33; P < 0.001). Hospital site, earlier year of ART start, spending less time enrolled in HIV care prior to ART initiation, receiving a non-standard ART regimen, lacking counseling prior to ART initiation, and having a higher body mass index were also associated with attrition risk. CONCLUSIONS: The findings suggest quality improvement interventions at the two hospitals, including: enhanced retention support and transportation subsidies for patients accessing care from remote areas; counseling for all patients prior to ART initiation; timely outreach to patients who miss ART pick-ups; "bridging services" for patients transferring care to alternative facilities; routine screening for anticipated interruptions in future ART pick-ups; and medical case review for patients placed on non-standard ART regimens. The findings are also relevant for policymaking on decentralization of ART services in Haiti. |
Development of an electronic medical record based alert for risk of HIV treatment failure in a low-resource setting
Puttkammer N , Zeliadt S , Balan JG , Baseman J , Destine R , Domercant JW , France G , Hyppolite N , Pelletier V , Raphael NA , Sherr K , Yuhas K , Barnhart S . PLoS One 2014 9 (11) e112261 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 iSante. 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. |
Before and after the earthquake: a case study of attrition from the HIV antiretroviral therapy program in Haiti

Glob Health Action 2014 7 (1) 24572 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 Jeremie, 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. Jeremie 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. |
Cautious optimism on public health in post-earthquake Haiti
Vertefeuille JF , Dowell SF , Domercant JW , Tappero JW . Lancet 2013 381 (9866) 517-9 For many decades, Haiti has had poor health-service statistics and some of the highest rates of disease in the Americas region. Before 2010, only 17% of the Haitian population had access to appropriate sanitation, measles vaccine coverage was just 47%, HIV prevalence was 1·9%, and lymphatic filariasis affected 7% of the population.1, 2, 3, 4 | On Jan 12, 2010, a 7·0 magnitude earthquake struck Haiti, resulting in the deaths of more than 200 000 people, destruction of infrastructure, and further weakening of an already fragile health system.5 Although no-one doubted the resilience of the Haitian people, both international and domestic public health organisations recognised the vulnerability that this national disaster had created. International aid arrived quickly after the earthquake to provide for basic needs, but there was a growing feeling that the disaster should prompt the transformation of Haiti's health-care system. However, the Haitian Government had only just begun efforts to coordinate this process and to define medium-term goals5 when the inadvertent introduction of Vibrio cholerae in October, 2010 resulted in the worst cholera epidemic experienced by a single country in more than a century.6 | As the Haitian health system began to recover from the cholera epidemic, the Ministry of Public Health and Population (MSPP) started to look beyond emergency responses and towards improvement of longer-term health care for the population. In a collaborative process led by MSPP, the US Centers for Disease Control and Prevention (CDC) and other organisations identified seven public health impact goals (panel) that support national health priorities to improve health service delivery and disease outcomes in the years ahead. |
Rapid development and use of a nationwide training program for cholera management, Haiti, 2010
Tauxe RV , Lynch M , Lambert Y , Sobel J , Domercant JW , Khan A . Emerg Infect Dis 2011 17 (11) 2094-2098 When epidemic cholera appeared in Haiti in October 2010, the medical community there had virtually no experience with the disease and needed rapid training as the epidemic spread throughout the country. We developed a set of training materials specific to Haiti and launched a cascading training effort. Through a training-of-trainers course in November 14-15, 2010, and department-level training conducted in French and Creole over the following 3 weeks, 521 persons were trained and equipped to further train staff at the institutions where they worked. After the training, the hospitalized cholera patients' case-fatality rate dropped from 4% to 2% by mid-December and was 1% by January 2011. Continuing in-service training, monitoring and evaluation, and integration of cholera management into regular clinical training will help sustain this success. |
Knowledge, attitudes, and practices related to treatment and prevention of cholera, Haiti, 2010

Emerg Infect Dis 2011 17 (11) 2158-2161 In response to the recent cholera outbreak, a public health response targeted high-risk communities, including resource-poor communities in Port-au-Prince, Haiti. A survey covering knowledge and practices indicated that hygiene messages were received and induced behavior change, specifically related to water treatment practices. Self-reported household water treatment increased from 30.3% to 73.9%. |
Cholera prevention training materials for community health workers, Haiti, 2010-2011

Emerg Infect Dis 2011 17 (11) 2162-2165 Stopping the spread of the cholera epidemic in Haiti required engaging community health workers (CHWs) in prevention and treatment activities. The Centers for Disease Control and Prevention collaborated with the Haitian Ministry of Public Health and Population to develop CHW educational materials, train >1,100 CHWs, and evaluate training efforts. |
