Ritengo che un punto di forza del lavoro sia stata l'interfaccia delle SIF implementate sulle HIS.
Le informazioni che gli operatori hanno a disposizione praticamente totale, e la semplicit
dell'interfaccia sviluppata tale da rendere quasi superflua la documentazione cartacea sull'
implementazione della logica e le soglie di blocco, un vero valore aggiunto.
