[Evaluation of the appropriateness of stays in a third level hospital]

Appropriateness Evaluation Protocol (AEP) has proved to be a useful tool for reviewing the utilisation of hospital resources. The aim of this article is to determine the proportion of inappropriate admissions and stays, as well as their causes, in patients hospitalised in the Hospital Clínico Universitario de Valladolid (HCUV).

A retrospective, analytical, observational, cohort study. The period of study was one year (2004). A sample of 1,630 admissions was gathered. Case definition, variables of interest and the model of data gathering were carried out in accordance with the AEP. The principal variables were analysed by means of a basal analysis and the possible relations between them.

Fifty-four percent of the admissions showed at least one day of inappropriate stay, with the global rate of inappropriateness being 34.17%. Amongst the causes responsible for inappropriateness, 68.9% of admissions showed at least one criterion falling under the responsibility of the doctor or the hospital, and 51.3% were due to delays in the development of study or treatment.

The utilisation of methods of identification of inappropriate use such as AEP show applications both in planning and in hospital management, by making it possible to identify hospital problems causing delays, principally problems of an organisational type, making it possible to develop interventions aimed at reducing inappropriate use.
