The Temple-led Emergency care research network (Temple-SIREN) is comprised of multiple community and academic medical centers and EMS providers throughout Philadelphia, New Jersey, Delaware, and Maryland to execute SIREN emergency care trials. To meet the needs for specific study enrollment, Temple-SIREN engaged the highest volume emergency and trauma centers and the busiest EMS systems in the region. This large hub-spoke network serves very diverse populations in densely populated cities as well as highly affluent suburban areas to rural regions of Bucks and Berks counties in PA Dutch country. Temple-SIREN Hub and spoke leaders are committed to emergency care research and are active in trials of acute cardiopulmonary and neurological illness and traumatic brain injury trials. Through collaboration and hub oversight, the Temple-SIREN group expects to significantly contribute SIREN studies' enrollment. In addition, we plan to stay ahead of the curve by translating preclinical work to the bedside and using our highly diverse regional network for studies that needs of our diverse communities. The Temple-SIREN Hub staff will work closely with participating site investigators and coordinators from multiple disciplines to efficiently execute SIREN studies. Mechanisms to enhance efficiency and quality of clinical research across sites include use of a common informatics system to identify potential study patients; frequent communication with investigators and coordinators via webinars and conference calls; diligent site management focused on good clinical research practices and compliance, and regular Hub-spoke meetings to provide additional training by study role. Temple-SIREN investigators and coordinators will participate in SIREN clinical coordinating center and data management center and ad hoc working groups to develop SIREN studies. The Temple-SIREN Hub team would benefit from participating in this coordinated approach to emergency care research as would the people of Philadelphia and the surrounding communities served by our hospitals and EMS systems.
