Abstract


Multitudinous studies have suggested that a prolonged QT interval may be a marker of increased risk of sudden death in patients with a variety of diseases, and have discovered an inverse relationship between the QT interval and patient mortality in the general population that includes patients with or without heart attack. For safety, patients rely on the care of nurses, who have expertise in overseeing high-tech monitors. Existing nursing educational programs concerning QT interval as primarily focus on measurements of QT intervals, and they reveal much inappropriate measurement-taking and poor knowledge about QT intervals. An educational program for critical care nurses on strategies for managing patients with QT prolongation to prevent related cardiovascular events is via mixed methods approach. Thirty-nine subjects enrolled in this study completed three phases in one hospital. Major findings of subjects’ knowledge, attittulde and practice are : 1. improved knowledge across all subjects; 2.moderate decreases in delay tests. 3.Low correct response in measurement of QT interval and prolongation causes of QT intervals. 3. subjects’ knowledge of normal ranges of QT intervals in post-tests showed increases; however, correct answer rates remained below 70%. 4.Qualitative findings on awareness and behavioral changes revealed that many subjects focused better while administering QT- prolonging drugs and discussed considerations with nursing or medical colleques. Although some knowledge remained unclear for critical care nurses at the post-test, the total right response rate declined slightly for delay tests and the project raised awareness among subjects about QT interval prolongation and their behavioral changes when encountering this critical situation. Lastly, we opened up several new areas of investigation including multifaceted nursing issues.
