Evaluation of rule effectiveness and positive predictive value of clinical rules in a Dutch clinical decision support system in daily hospital pharmacy practice

摘要

IntroductionOur advanced clinical decision support (CDS) system, entitled ‘adverse drug event alerting system’ (ADEAS), is in daily use in our hospital pharmacy. It is used by hospital pharmacists to select patients at risk of possible adverse drug events (ADEs).

The clinical rules are all medication related and are formulated using seven risk categories.
