Validación de una clasificación de errores de medicación para su utilización en quimioterapia / Validating a Classification Scheme for Medication Errors to be Used in Chemotherapy

Objetivo Validar una hoja de clasificación de errores de medicación asociados a medicamentos antineoplásicos. Métodos Estudio prospectivo. Se diseñó una hoja de recogida de datos sobre la base de la clasificación de la American Society of Health-System Pharmacists. Dos observadores revisaron las líneas de tratamiento de las prescripciones de quimioterapia del Servicio de Hematología durante un mes y clasificaron los errores detectados. Se analizó la concordancia interobservador mediante el test del índice kappa. Se revisaron las categorías de error en las que se obtuvo una concordancia moderada o inferior y se valoró si era necesaria su modificación. Resultados Se analizaron un total de 23 categorías de error y se revisaron 162 líneas de tratamiento. Únicamente una de las categorías fue valorable en función de su prevalencia de error, la de prescripción incompleta o ambigua (índice kappa=0,458=concordancia moderada). Se analizaron las causas y se desglosaron subapartados dentro de esta categoría. Conclusión Nuestros resultados evidenciaron la necesidad de la revisión de la clasificación de errores. Es necesario disponer de herramientas validadas para avanzar en la caracterización de este tipo de errores de medicación (AU)

Objective To validate a classification sheet for medication errors associated with antineoplastic medication. Method Prospective study. A data sheet was designed based on ASHP's classification. Two observers reviewed the treatment prescribed for chemotherapy from the Haematology Department during a month and they classified the errors detected. The interobserver concordance was analysed using the kappa index test. The error categories with a moderate or lower concordance were reviewed, and the need to modify them was evaluated. Results A total of 23 error categories were analysed and 162 lines of treatment were reviewed. Only one of the categories was assessable in accordance with its error prevalence, which was the category for incomplete or ambiguous prescriptions (kappa index=0.458=moderate concordance). The causes were analysed and subsections within this category itemised. Conclusion Our results proved the need to review error classification. Validated tools need to be made available so as to make progress in characterising this type of medication error (AU)
