Objective: The objective of this study was to identify out-of-hospital cardiac arrest characteristics for patients treated by collegiate-based emergency medical services (CBEMS) organizations. Participants: CBEMS organizations provided data via the National Collegiate EMS Foundation Cardiac Arrest Data Registry. Methods: CBEMS organization details, patient demographics, cardiac arrest characteristics and treatments, and prehospital outcomes for cases spanning October 2007 to May 2020 were analyzed with descriptive statistics. Results: There were 65 OHCA entries. The majority were for male patients (82%) and a notable number of cases occurred in patients 45 years of age or younger (41%). Cases were frequently witnessed (71%) with high rates of bystander cardiopulmonary resuscitation (57%) and defibrillation (29%) prior to EMS arrival. Almost half of the patients (48%) had achieved return of spontaneous circulation until care was transferred to a provider of equal/higher level. Conclusions: CBEMS organizations may be well situated to respond rapidly to on-campus OHCAs.
