Abstract:
Malfunction of clinical decision support (CDS) systems could lead to undesirable consequences. We evaluated CDS malfunctions associated to the use of electrocardiograms (ECG) as data source to detect a delta in the corrected QT interval (QTc) ≥ 60 milliseconds (QTc current ECG minus QTc previous ECG). Our preliminary results showed that several common clinical conditions can cause changes in the electrocardiogram and result in errors when calculating the QTc interval and subsequently the delta QT between 2 serial ECGs. These errors cannot be easily identified by the electronic systems and are a source of CDS malfunction.
