Abstract
Objectives
This study sought to determine whether a radiation safety time-out reduces radiation exposure in electrophysiology procedures.
Background
Time-outs are integral to improving quality and safety. The authors hypothesized that a radiation safety time-out would reduce radiation exposure levels for patients and the health care team members.
Methods
The study was performed at the New York University Langone Health Electrophysiology Lab. Baseline data were collected for 6 months prior to the time-out. On implementation of the time-out, data were collected prospectively with analyses to be performed every 3 months. The primary endpoint was dose area product. The secondary endpoints included reference point dose, fluoroscopy time, use of additional shielding, and use of alternative imaging such as intracardiac and intravascular ultrasound.
Results
A total of 1,040 patient cases were included. The median dose area product prior to time-out was 18.7 Gy∙cm2, and the median during the time-out was [Read more…]
