Association of Rapid Care Process Implementation on Reperfusion Times Across Multiple ST-Segment-Elevation Myocardial...

Area of Science:

• Cardiology
• Health Systems Research
• Public Health

Background:

• The Mission: Lifeline STEMI Systems Accelerator program aimed to improve reperfusion times for ST-elevation myocardial infarction (STEMI) patients across 16 US metropolitan regions.
• This study assessed the association between the implementation of key care processes and improvements in system performance for STEMI treatment.

Purpose of the Study:

• To evaluate the impact of the STEMI Systems Accelerator program on the adoption of critical care processes.
• To determine if the implementation of these processes correlated with enhanced system performance in STEMI care.

Main Methods:

• A survey of 167 hospitals was conducted before (March 2012) and after (July 2014) the program intervention.
• Patient-level clinical data were merged with survey data to analyze the association between care process implementation and reperfusion times.
• Hospitals were categorized based on the implementation status of specific care processes: implemented, preexisting, or never implemented.

Main Results:

• Uptake of four key care processes significantly increased post-intervention, including prehospital catheterization laboratory activation (62% to 91%) and single call transfer protocols (45% to 70%).
• Hospitals implementing prehospital activation demonstrated shorter median first medical contact-to-device times (88 minutes) compared to those with preexisting (89 minutes) or never implemented (98 minutes) processes.
• Implementation of single call transfer protocols and emergency department bypass was also associated with significantly reduced median first medical contact-to-device times for STEMI patients.

Conclusions:

• The Accelerator program successfully increased the adoption of crucial care processes for STEMI management.
• The implementation of these key processes, including prehospital activation, single call transfer, and ED bypass, is associated with improved system performance and reduced treatment times.
• These findings support the establishment of regional STEMI networks emphasizing these evidence-based care processes.
