Valutazione dell’appropriatezza dei ricoveri ospedalieri pubblici nella Regione Abruzzo tramite PRUO: risultati per presidio e disciplina, principali predittori e potenziali implicazioni.

In the context of a wide healthcare system reorganization, the Abruzzo Region of Italy used the Appropriateness Evaluation Protocol (AEP) to carry out a systematic evaluation of the appropriateness of the admissions performed during 2006 in all public hospitals. After specific training courses, a sample representative of all ordinary admissions was assessed twice: first by regional investigators (external assessment) then by the local personnel (internal assessment). Random-effect logistic regression was used to evaluate potential inappropriateness predictors. On a total of 13081 hospital days (2393 hospitalizations), 39.7% (95% Confidence interval: 38.9%-40.6%) were inappropriate at the regional assessment; 39.5% at the internal assessment, with high correlation between the two controls (K = 0.73). Another 10.4% of admissions, excluded by the evaluation, was assigned to DRGs at high risk of inappropriateness and should be considered. In single hospitals, the inappropriateness ranged between 17.9% and 57.9%, with large variation across wards. Additional significant predictors of inappropriateness were the day and hour of admission and hospital size, with lower inappropriateness in bigger ones. In 2006, there was a large degree of hospital misuse in public hospitals in the Abruzzo Region. The approach used in the survey may have contributed to the drastic reduction of the number of ordinary admissions observed in the Region between 2006 and 2007.
