Description
Summary:The aim of this study was to determine whether the adoption of new performance processes reduced the door-to-balloon time for primary percutaneous coronary intervention (PCI). To reduce the door-to-balloon time, we adopted 3 new performance processes: concurrent activation at the emergency department rather than stepwise activation; direct phone call rather than using a pager or message; patient transferred to catheterization laboratory before the PCI team arrive. A total of 139 consecutive patients were compared before and after the new performance processes. After the adoption of the new processes, median door-to-balloon time reduced significantly from 133 to 76 minutes (P < .0001) and patients undergoing primary PCI within 90 minutes increased significantly from 16% to 72% (P < .0001). Among the subdivisions of the door-to-balloon time, door-to-consent time and door-to-laboratory arrival time decreased significantly (50.0 vs 20.5 minutes, P < .0001; 95.0 vs 40.0 minutes, P < .0001, respectively).
