RESUMEN
La esquizofrenia genera elevados costos al sistema de salud. La falta de adherencia al tratamiento es una de las principales causas de recaídas y hospitalizaciones en la esquizofrenia. Lo anterior conduce a un pobre pronóstico y deterioro funcional de los pacientes. La risperidona inyectable de liberación prolongada (RILP) ha demostrado su eficacia en el tratamiento de la esquizofrenia, ofreciendo la posibilidad de que los pacientes tengan una mayor adherencia terapéutica.
Objetivo: Determinar la eficacia y efecto sobre la funcionalidad y el uso de recursos hospitalarios de la RILP en una muestra de pacientes con esquizofrenia de América Latina a dos años de seguimiento.
Método: El Registro Electrónico de Adherencia al Tratamiento de Esquizofrenia en Latinoamérica (e-STAR) es un estudio observacional del uso de la RILP en la esquizofrenia. Se reclutaron pacientes de México, Colombia y Brasil. Se registró la información clínica del paciente un año previo al inicio del tratamiento con la RILP y de forma prospectiva cada tres meses hasta cumplir los 24 meses de seguimiento. Se registraron las hospitalizaciones y el esquema de tratamiento con la RILP. La escala de Impresión Clínica Global-Gravedad (CGI-S) se utilizó como indicador de eficacia mientras que la Escala Global de Funcionamiento (GAF) y la Escala de Desempeño Personal y Social (PSP) se utilizaron para evaluar el funcionamiento.
Resultados: Setenta y tres pacientes completaron los dos años de seguimiento. La proporción de pacientes hospitalizados disminuyó del 16.4 al 4.1% después de dos años de tratamiento con la RILP. El 2.7% descontinuó el tratamiento debido a falta de eficacia. Se observó una mejoría significativa en cuanto a la gravedad del padecimiento y el funcionamiento global.
Discusión: En la práctica clínica cotidiana, la RILP resulta ser un tratamiento a largo plazo efectivo para la esquizofrenia con el beneficio adicional de una menor utilización de recursos del sistema de salud.
