Patient attrition from the HIV antiretroviral therapy program at two hospitals in Haiti / Abandono del programa de tratamiento antirretrovírico de la infección por el VIH en pacientes de dos hospitales de Haití

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 iSanté 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.

OBJETIVO: Determinar los factores asociados con el abandono del tratamiento antirretrovírico en los pacientes que iniciaron el tratamiento en el período del 2005 al 2011 en dos grandes hospitales públicos de nivel departamental, y fundamentar las intervenciones necesarias para mejorar la retención de los pacientes en el tratamiento. MÉTODOS: Este estudio retrospectivo de cohortes empleó los datos del sistema de registro médico electrónico iSanté. Se describieron los niveles de abandono del tratamiento y se exploraron los factores demográficos, clínicos, temporales y de utilización de los servicios que se asociaban con su abandono, usando métodos de análisis del tiempo trascurrido hasta un evento. RESULTADOS: El abandono del tratamiento entre los 2 023 pacientes incluidos en el estudio fue en promedio de 17,0 por 100 personas-años (intervalo de confianza (IC) de 95%: 15,8-18,3). En los análisis ajustados, el riesgo de abandono del tratamiento fue de hasta 89% mayor en los pacientes que vivían en comunas distantes, en comparación con los pacientes que vivían en la misma comuna en que se ubicaba el hospital (razón de riesgo: 1,89; IC de 95%: 1,54-2,33; P < 0,001). La ubicación del hospital, el inicio del tratamiento en un año calendario anterior, un menor tiempo de inclusión en el programa de atención a la infección por el VIH antes de iniciar el tratamiento, la administración de un régimen terapéutico no estándar, la falta de orientación antes de iniciar el tratamiento y un mayor índice de masa corporal también se asociaron con un riesgo más elevado de abandono. CONCLUSIONES: Los resultados sugieren algunas intervenciones de mejora de la calidad en ambos hospitales, entre ellas: un mayor apoyo a la retención y subsidios de transporte para los pacientes que acuden desde zonas remotas para ser atendidos; la orientación a todos los pacientes antes del inicio del tratamiento antirretrovírico; el contacto oportuno de los servicios con los pacientes que omiten alguna recogida de medicación; "servicios de conexión" para transferir la atención de los pacientes a otros establecimientos alternativos; el tamizaje sistemático de las interrupciones previstas en las próximas recogidas de medicación; y la revisión médica de los casos de pacientes que siguen un tratamiento no estándar. Estos hallazgos son también pertinentes en materia de formulación de políticas de descentralización de los servicios de tratamiento antirretrovírico en Haití.

Before and after the earthquake: a case study of attrition from the HIV antiretroviral therapy program in Haiti.

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.

Implementation and expansion of an electronic medical record for HIV care and treatment in Haiti: an assessment of system use and the impact of large-scale disruptions.

PURPOSE: System use is a key criterion of success in an electronic medical record (EMR) implementation, and there is little research on long-term use of systems following implementation. The aim of the paper was to describe the development, implementation and use of iSanté, Haiti's national HIV care and treatment EMR. METHODS: To build a picture of the history of iSanté, we interviewed 11 staff involved with the development and implementation of the EMR, and reviewed organization records. Data entry and report use were ascertained by querying the central patient database. RESULTS: By the end of 2010 there were 67 sites with iSanté installed, and the scope of the system had been expanded to include primary care and obstetrics and gynecology. New functionality includes data forms specific to subpopulations, the ability to transfer patient records among clinics, and integration with an electronic laboratory system. We observed fluctuations in use over time, with substantial reductions in the number of active sites during times of large-scale disruptions in Haiti. A surge in report use following the January 2010 earthquake suggests that clinics found the EMR to be a valuable source of data during the recovery phase. CONCLUSION: There is real potential for EMRs in developing countries to improve clinical practice and make data available for efficient reporting, quality improvement and other population health uses. An approach of continuous system improvement, combined with regular assessments of use, is necessary for achieving an effective, national implementation of a standardized EMR. We have achieved successes in terms of rolling out new functionality and expanding to new sites, but more work remains to be done to improve perceptions of data quality and increase use of population data for accurate and timely reporting.
