          Abstract

          Fundamentos: los estudios de utilización de medicamentos (EUM) precisan de indicadores precisos y universalmente aceptados para poder establecer comparaciones de sus resultados entre regiones y/o países así como a lo largo del tiempo en una zona determinada. Objetivo: comparar dos indicadores usados ampliamente en los EUM: la dosis diaria definida (DDD) y las unidades de venta (envases). Diseño: estudio longitudinal retrospectivo. Material y métodos: medimos el consumo de antibióticos de uso sistémico en la provincia de Valladolid en el periodo 1996-2000 a través de los datos proporcionados por IMS (International Marketing Services), estableciendo dicho consumo en DDD/1.000 habitantes/día y en envases/1.000 habitantes/año. Resultados: los datos obtenidos por los dos sistemas de indicadores son distintos, por un lado el estudio interanual en DDD muestra un incremento en el uso de antibióticos entre 1996 y 1999, mientras que al medirlo en envases la curva obtenida es decreciente durante todo el periodo. Por otra parte la clasificación de los subgrupos de antibióticos por importancia de consumo se vio alterada. Conclusiones: los resultados en los EUM se ven afectados en función de la unidad de medida elegida. En nuestra opinión la DDD presenta notables ventajas respecto a la medida en envases.

          Backgrounds: studies of drug use (SDU) require precise and universally accepted indicators to be able to establish comparisons of their results among regions and/or countries as well as along the time in a certain area. Objective: to compare two indicators widely used in SDU: the defined daily dose (DDD) and the sale units (packs). Design: longitudinal retrospective study. Material and methods: we measure the consumption of antibiotics for systemic use in the county of Valladolid in the period 1996-2000 through the data provided by IMS (International Marketing Services), establishing this consumption in DDD/1,000 inhabitants/day and in packs/1,000 inhabitants/year. Results: the data obtained by the two systems of indicators are different, on the one hand the interanual study in DDD shows an increment in the use of antibiotics between 1996 and 1999, while when measuring it in packs the obtained curve is falling during the whole period. On the other hand the classification of the subgroups of antibiotics by importance consumption was altered. Conclusions: the results in the SDU are affected according to the measure unit elected. In our opinion the DDD presents remarkable advantages regarding the measure in packs.
