Estudio de incidencia de eventos adversos en una clínica privada en Chile / Incidence of adverse events in a private hospital in Chile

Objetivos. Determinar la incidencia y tipos de eventos adversos (EA) en pacientes hospitalizados en la Clínica Vespucio, describir sus causas inmediatas, definir los EA evitables y determinar los servicios con mayor tasa. Material y método. Estudio retrospectivo de cohortes en pacientes dados de alta entre el 16 y el 31 de enero de 2012. Para la identificación de EA se revisan las fichas clínicas y se les aplica la guía de cribado de efectos adversos adaptada del estudio de Harvard. A los pacientes con cribado positivo se les aplicó la versión española del Formulario modular para revisión retrospectiva de casos (Modular Review Form; MRF2) del Estudio Eneas de 2005. Resultados. Se incluyeron en el estudio 500 pacientes, de los que 31 presentaron EA relacionados con la asistencia sanitaria (6,2%), con una densidad cada 100 días/cama de 3,46 (leves 2,72, moderados 0,65 y graves 0,09). Los procesos asociados fueron: cuidados 32,4%, procedimientos 32,4%, medicación 13,5%, infecciones nosocomiales 10,8% y diagnóstico 8,1%. Se consideró evitable el 67,6%. Un 40,5% requirió procedimientos adicionales y un 35,1% tratamientos adicionales. En un 5,4% se prolongó la estancia media 5,5 días y un 8,1% causó reingreso. El 91,9% no generó incapacidad. Los servicios con mayor tasa por cada 100 altas fueron: unidad de pacientes críticos (21,4), obstetricia y ginecología (7) y médico quirúrgico (6). Conclusiones. Este es el primer estudio realizado en un hospital privado en nuestro país y que nos permitió identificar la incidencia y tasa global y por servicios de EA, su gravedad, evitabilidad y sus factores causales (AU)

Objectives. To determine the incidence and type of adverse events (AE) in hospitalized patients in Vespucio Clinic, to describe their immediate causes, define avoidable AE and determine the services with highest AE rate Material and method. Retrospective cohort study, in patients discharged between 16 and 31 January 2012. For the identification of AE, medical history was reviewed, and the AE screening guide adapted from the Harvard study was applied. The Spanish version of Modular Review Form MRF2 used in the ENEAS 2005 Study was applied to the patients with positive screening. Results. From the 500 patients studied, 31 had some AE related to health care (6.2%), with an incidence of 3.46 for every 100 patient bed days (minor events 2.72, moderate 0.65, and severe 0.09). The associated processes were: Care 32.4%, medication 13.5%, infections associated with health care10.8%, and diagnostics 8.1%. More than two-thirds (67.6%) were considered avoidable. Of the adverse events, 40.5% required additional procedures, and 35.1% additional treatment. Hospital stay was extended by an average of 5.5 days in 5.4%, and 8.11% led to re-admission. Most of them (91.9% did not cause any incapacity. The departments with the highest AE rates per 100 bed patients days were: Critical Care Unit (21.4), obstetrics and gynecology (7), and medical/surgical wards (6) Conclusions. This is the first study conducted in a private hospital in our country that allowed us to identify the incidence, overall rate, and the rate by departments of adverse events, their severity, preventability and causal factors (AU)
