Pharmacist Use of ECG to Inform Drug Therapy Decisions for Patients Receiving QT Prolonging Medications
Completed · Not applicable
Conditions studied: Torsades de Pointe Caused by Drug (Disorder), Torsades de Pointes, Qt Interval, Variation in
In brief
Torsade de pointes (TdP) is a cardiac arrhythmia associated with QT interval prolongation which may lead to cardiac arrest. Prescription medications which cause QT interval prolongation are commonly used in daily practice. To lessen risk of TdP, pharmacists work to minimize combinations of QT interval prolonging drugs. If community pharmacists had real-time information about a patient's QT interval duration, this would have the direct ability to inform their decision making about which patients may be at highest risk of TdP and who may need heightened avoidance of QT prolonging drugs. This project will provide 3 community pharmacies with mobile ECG devices to easily determine QT intervals among patients who have a prescription profile alert for QT interval prolongation. Study outcomes will include: frequency of QT interval prolongation, changes in drug therapy related to QT interval determination, and patient and pharmacist satisfaction with having pharmacist assessment of QT interval.
