Physicians, nurses and pharmacists play central roles in the team effort to use medications wisely. This section includes tools to assist with prescribing and dispensing of medications, four searchable lists of drugs arranged by their potential to cause QT prolongation and torsades, and instructions for submitting a case report to the QT Registry (The International Registry for Drug-Induced Arrhythmias). We also provide a variety of educational resources and links to other useful sites that give additional information on therapeutics. The goal of these efforts is to provide professionals with access to information that will help improve patient safety.
