Unfortunately, according to an article published in JAMA Cardiology, "Mortality rates are 10-fold higher than for out-of-hospital STEMI and can approach mortality rates associated with cardiogenic shock."
Why are these rates so much higher for in-hospital versus out-of-hospital patients? Researchers identify three main areas of delay in treating in-hospital STEMI, which may contribute to poorer outcomes:
1. Delay in ECG acquisition
2. Delay in ECG interpretation
3. Delay in activation of STEMI teams
What can be done to reduce the delay in treatment for in-hospital STEMI patients? First, hospital teams need a lower threshold for performing an ECG in patients exhibiting first signs of myocardial infarction. Second, hospitals need a process for QUICKLY getting the ECG into the hands of the cardiologist for immediate interpretation. And finally, a reliable, effective, consistent system for activating the STEMI system of care is essential.
Technologies like pagers and fax machines were never an effective match for managing complex conditions like STEMI, particularly when in-hospital patients present different challenges than those whose conditions originate outside the hospital. The health systems that will be most successful in meeting those challenges will be those who have a consistent system that reduces variance in the treatment process, and works regardless of method of arrival. As the ACC points out, "The process of STEMI team or catheterization laboratory activation for an in-hospital STEMI should as much as possible mirror that for patients who present to the emergency department and are diagnosed as having STEMI."
Mobile technology offers a solution to these obstacles -- ECG findings can be instantly transmitted to individuals or entire dynamic teams, and activation of those teams can now be done with a single tap of a button on care coordination app platforms like Pulsara.
