The incidence of the number of laboratory tests has been increasing in recent years, and many authors find that their inappropriateness represents one of the main causes of the rising demand for laboratory tests. Some literature evaluates the costs of inappropriateness and the effectiveness of actions aiming at reducing the incidence of laboratory tests; however, it has produced conflicting results so far. This paper aims at analyzing the essential aspects to be included in the evaluation of the impact on the introduction of a computer system prototype (SIP) within a hospital department. SIP is able to detect if a laboratory test has already been performed on the same patient, when a new laboratory test is requested; thus the SIP allows the clinicians to assess the opportunity to repeat it. Considering costs and outcomes, measured before and after the implementation of the new technology (SIP), a model for the evaluation of its impact is proposed.

L’incidenza del numero di esami di laboratorio è aumentata negli ultimi anni e si ritiene che l’inappropriatezza ne rappresenti una delle cause principali. Vari contributi tendenti a valutare i costi derivanti dall’inappropriatezza e l’efficacia di azioni volte a ridurne l’incidenza hanno prodotto, ad oggi, risultati contrastanti. Alla luce dell’analisi della letteratura e dei primi risultati di uno studio realizzato in un contesto ospedaliero, tale lavoro intende proporre un’analisi metodologica degli aspetti essenziali da includere nella valutazione di impatto relativa all’introduzione di un sistema informatico prototipale (SIP) del tipo order entry nelle Aziende sanitarie. Il lavoro intende anche presentare le prime evidenze relative agli effetti derivanti dall’utilizzo del SIP sul numero e sui costi degli esami di laboratorio eseguiti.

Abstract

The incidence of the number of laboratory tests has been increasing in recent years, and many authors find that their inappropriateness represents one of the main causes of the rising demand for laboratory tests. Some literature evaluates the costs of inappropriateness and the effectiveness of actions aiming at reducing the incidence of laboratory tests; however, it has produced conflicting results so far. This paper aims at analyzing the essential aspects to be included in the evaluation of the impact on the introduction of a computer system prototype (SIP) within a hospital department. SIP is able to detect if a laboratory test has already been performed on the same patient, when a new laboratory test is requested; thus the SIP allows the clinicians to assess the opportunity to repeat it. Considering costs and outcomes, measured before and after the implementation of the new technology (SIP), a model for the evaluation of its impact is proposed.
