Abstract WP3: EMS Routing for Endovascular Patients- One Health Care Systems Successful Model
Background: Annually, over 1500 stroke patients are seen within a large metropolitan health system. The health system encompasses a designated comprehensive (CSC) and multiple primary (PSC) stroke hospitals with varying capabilities to manage stroke patients, resulting in varied care delivery. While CSCs mitigate inconsistencies by establishing a standard of stroke care, one shortcoming of the CSC model is lack of regulation in transfer of patients between centers within a health system containing multiple stroke designations.
Purpose: The purpose of the project was to create a streamlined, emergency stroke work-up process across the various levels of stroke hospitals and to apply rapid routing practices for EMS when transferring stroke patients between facilities. These changes could reduce treatment times and optimize resources to facilitate transportation of stroke patients to the appropriate center.
Methods: The system stroke steering team, in collaboration with regional EMS directors initiated 5 primary processes to reduce delays. These included 1) door in to door out times of 60 minutes, 2) loading radiology images into a cloud environment, 3) development of EMS algorithms, 4) prompt follow-up reports on stroke transfers, and 5) rapid loop-closure on gaps in the process. A reduction in door-to-therapy time and measures of patient outcome were used as indicators for effectiveness.
Results: Implementation of a streamlined ED process and new routing protocol was associated with improved door-to-door times, door-to-treatment times and EMS transport times. Additionally, risk-adjusted mortality decreased from 0.7 in 2012 to 0.3 in 2014. Similarly, thrombolytic complications in intravenous and endovascular patients decreased from 7.5% in 2012 to 1.7% in 2014, while treatment rates in both increased.
Conclusion: Within a large health system, utilizing a consistent ED process and new EMS routing protocol could contribute to improved outcomes. This raises the possibility that implementing system routing practices may improve collaboration within stroke systems of care and advance the CSC model.
