PHILADELPHIA— As violence in Philadelphia continues at a high rate, “scoop-and-run” hospital transports — when a responding police officer takes a gunshot or stabbing victim to a trauma center as quickly as possible — have become a time-tested means for delivering patients to life-saving treatment. Twice as many patients are now brought to trauma centers by police, with survival rates comparable to those transported by EMS professionals, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania who examined five years of data. These findings were published today in JAMA Network Open.
“We saw that patients transported by police are often more seriously injured than patients transported by EMS, but after controlling for significant differences between groups, police-transported patients have similar mortality levels,” said the study’s lead author, Jeremy Cannon, MD, the Trauma medical director and section chief of Trauma at Penn Medicine. “This study highlights just how crucial to patient care police have become.”
While most police officers’ roles are typically limited to keeping the peace and solving crime, for approximately 25 years, the Philadelphia Police Department has authorized its officers to quickly transport trauma victims to a trauma center if they feel the situation is dire. A Penn Medicine analysis of data from more than a decade ago found no significant differences between the survival of those with penetrating trauma (gunshots, stab wounds, etc.) who were transported via police or ambulance.
But that study took place before a key change was made to the department’s protocol.
“Since the last study, all patrol officers in the city of Philadelphia were issued tourniquets to control extremity hemorrhage during emergencies,” said the study’s first author, Eric Winter, a medical student at the Perelman School of Medicine. “By giving police officers the ability to quickly manage peripheral bleeding, this tourniquet initiative had the potential to enhance the benefit of rapid police transport to the hospital. We know that Philadelphia’s EMS personnel do an exceptional job, but since there’s an emphasis on having the first available responder move victims as quickly as possible, we felt further analysis was needed to assess the impact of this new policy.”
The new Penn analysis, however, shows that the overall survival rate, measured when patients are discharged from the trauma center, was relatively unchanged after the tourniquet initiative. This raises the question of whether the tourniquet initiative has been effective. Cannon explained that the tourniquets themselves have actually worked, but some external factors sometimes limit their use. These include the ability to identify extremity wounds quickly, whether officers have a tourniquet immediately available, and the cost of tourniquet replacement.
“We are encouraging police to use tourniquets above wounds to the arms and legs whenever they can,” Cannon said. “And to ensure they can do it again if needed, we give them a replacement tourniquet when they come into the trauma center.”
While there were similar rates of survival found between the two analyses, the study uncovered one significant shift: by 2018, a large majority of trauma victims were being taken to the hospital via police.
In 2014, 328 patients were transported to the hospital by police, and that increased to 489 by the end of 2018, the final year studied. EMS personnel transported 246 patients in 2014 and 281 in 2018. This means that, by the end of the study period, roughly two of every three gunshot or stabbing victims were transported to a trauma center by police rather than EMS personnel. This was a complete flip from the earlier study a decade ago, when well over twice as many patients were transported via ambulance than by police cruiser.
Amid the coronavirus pandemic, gun violence in Philadelphia has surged. Although a comprehensive analysis of this experience has not been reported, Cannon said that he and his colleagues have been pleased to see several “unexpected survivors” they might not have otherwise seen without this police transport policy.
Moving forward, Cannon, Winter, and their colleagues are planning two follow-up studies. One is set to examine outcomes by the geographical origin of the victim. The other will look at how much time it takes for patients to be transported by police to the hospital.
“We hope that these studies will be beneficial to our patients and to policymakers alike,” Cannon said. “We also hope that we will be able to share our experiences with other cities looking to re-examine the role of police in our communities.”
Other authors on this study include Allyson Hynes, Kaitlyn Shultz, Daniel Holena, and Neil Malhotra.

Penn Medicine is one of the world’s leading academic medical centers, dedicated to the related missions of medical education, biomedical research, and excellence in patient care. Penn Medicine consists of the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania (founded in 1765 as the nation’s first medical school) and the University of Pennsylvania Health System, which together form a $8.9 billion enterprise.
The Perelman School of Medicine has been ranked among the top medical schools in the United States for more than 20 years, according to U.S. News & World Report's survey of research-oriented medical schools. The School is consistently among the nation's top recipients of funding from the National Institutes of Health, with $496 million awarded in the 2020 fiscal year.
The University of Pennsylvania Health System’s patient care facilities include: the Hospital of the University of Pennsylvania and Penn Presbyterian Medical Center—which are recognized as one of the nation’s top “Honor Roll” hospitals by U.S. News & World Report—Chester County Hospital; Lancaster General Health; Penn Medicine Princeton Health; and Pennsylvania Hospital, the nation’s first hospital, founded in 1751. Additional facilities and enterprises include Good Shepherd Penn Partners, Penn Medicine at Home, Lancaster Behavioral Health Hospital, and Princeton House Behavioral Health, among others.
Penn Medicine is powered by a talented and dedicated workforce of more than 44,000 people. The organization also has alliances with top community health systems across both Southeastern Pennsylvania and Southern New Jersey, creating more options for patients no matter where they live.
Penn Medicine is committed to improving lives and health through a variety of community-based programs and activities. In fiscal year 2020, Penn Medicine provided more than $563 million to benefit our community.
