Care quality monitoring of a ST-segment elevation myocardial infarction programme over a 5-year period

Area of Science:

• Cardiology
• Emergency Medicine
• Health Services Research

Background:

• ST-elevation myocardial infarction (STEMI) requires rapid reperfusion therapy.
• Prehospital electrocardiogram (ECG) acquisition and transmission can expedite diagnosis and treatment initiation.
• Optimizing treatment pathways is crucial for improving outcomes in STEMI patients.

Purpose of the Study:

• To evaluate the long-term impact of a prehospital ECG program on treatment times for STEMI patients.
• To assess the effectiveness of a STEMI protocol involving ECG tele-transmission, early cath lab activation, and direct patient routing.
• To analyze changes in key time metrics including ECG-to-balloon, door-to-balloon, and total ischemic times.

Main Methods:

• Retrospective analysis of 213 STEMI patients treated with primary percutaneous coronary intervention (PCI) from 2008-2012.
• Comparison with 54 STEMI patients from 2007 who did not benefit from prehospital ECG tele-transmission (control group).
• Data collection on first diagnostic ECG-to-balloon time, door-to-balloon time, and total ischemic time.

Main Results:

• First diagnostic ECG-to-balloon time decreased from 125.5 min in 2007 to 81 min by 2012 (P < 0.0001).
• Door-to-balloon time significantly reduced from 92.5 min in 2007 to 40.5 min by 2012 (P < 0.0001).
• Total ischemic time decreased from 200 min in 2007 to 163.5 min in 2012 (P < 0.042).

Conclusions:

• The prehospital ECG program demonstrated progressive improvements in STEMI treatment times over a 5-year period.
• Continuous data collection and monitoring are essential for optimizing STEMI care pathways.
• Implementing standardized protocols for prehospital ECGs and direct PCI routing significantly reduces delays in STEMI management.
