Background: Drugs are an important part of treating diseases but can also come with its risks. To reduce the risks, a system assisted pharmaceutical validation (SAPVAL) is being developed at Uppsala University Hospital. This will include the generation of alerts regarding different risks, sent to a clinical pharmacist who assesses whether the alerts should be forwarded to a physician or not. One of the risks included is QT prolongation, a relatively uncommon condition which however can result in sudden cardiac death. Aim: The aim was to map the management and the consequences of QT-related risk prescriptions and to determine the clinical relevance of QT-related alerts. Method: A retrospective cross-sectional study was performed at Uppsala University Hospital. It included the review of patients´ electronic health records (EHR) and determination of risk periods. The clinical relevance of the alerts was assessed by a physician and a developed flowchart. Results: 65 patients (age=71 ± 15 years, 54% women), and their 85 QT-related alerts were included, with a median risk period of 145 days. Within the risk period, 46 patients had an ECG taken with 35% having one or more prolonged QTc ≥ 480 ms. The risk of QT prolongation had been noticed or mitigated for 23% of the 65 patients. 89% of the alerts were concluded to be clinically relevant. Conclusion: The management and documentation of QT-related risks could be improved. It is also important to further study QT-related risk factors to better assess which patients are at the highest risk.
