BACKGROUND: Rapid transport to definitive care (“scoop and run”) verses field stabilization in trauma remains a topic of debate and has resulted in variability in pre-hospital policy. We aimed to identify trauma systems frequently using a true “scoop and run” police transport approach and to compare mortality rates between police and ground emergency medical services (EMS) transport. METHODS: Using the National Trauma Databank (NTDB), we identified adult gunshot and stab wound patients presenting to level 1 or 2 trauma centers from 2010-2012. Hospitals were grouped into their respective cities and regional trauma systems. Patients directly transported by police or ground EMS to trauma centers in the 100 most populous US trauma systems were included. Frequency of police transport was evaluated, identifying trauma systems with high utilization. Mortality rates and risk-adjusted odds ratio for mortality for police vs. EMS transport were derived. RESULTS: Of 88,564 total patients, 86,097 (97.2%) were transported by EMS and 2,467 (2.8%) by police. Unadjusted mortality was 17.7% for police transport and 11.6% for ground EMS. After risk-adjustment, patients transported by police were no more likely to die than those transported by EMS (OR=1.00, 95% CI: 0.69-1.45). Among all police transports, 87.8% occurred in three locations (Philadelphia, Sacramento, and Detroit). Within these trauma systems, unadjusted mortality was 19.9% for police transport and 13.5% for ground EMS. Risk-adjusted mortality was no different (OR=1.01, 95% CI: 0.68-1.50). CONCLUSIONS: Using trauma system level analyses, patients with penetrating injuries in urban trauma systems were found to have similar mortality for police and EMS transport. The majority of pre-hospital police transport in penetrating trauma occurs in three trauma systems. These cities represent ideal sites for additional system-level evaluation of pre-hospital transport policies. LEVEL OF EVIDENCE: III. Prognostic/Epidemiologic.
