Outcomes of pediatric trauma patients transported from rural and urban scenes.

OBJECTIVES: Mortality differences exist between victims of urban and rural trauma. It is unknown if these differences persist in those patients who survive to HEMS transport. This study examined the in-hospital mortality, hospital LOS, and discharge status of pediatric blunt trauma victims transported by HEMS from rural and urban scenes. METHODS: Retrospective review of pediatric (< 17) transports between 1997 and 2001. 130 rural and 419 urban pediatric patients transported to area trauma centers were identified from HEMS and registry records. RESULTS: Total mileage, flight times, and scene times were significantly longer for rural flights (P < 0.05). There were no significant differences between the groups with regard to age, gender, vitals, hospital/ICU days, and mortality. After controlling for ISS and mechanism of injury, urban patients were 9 times more likely to die compared to rural patients. CONCLUSIONS: Pediatric patients injured in urban areas had shorter total flight and scene times than pediatric patients flown from rural scenes. Higher adjusted in-hospital mortality rates in the urban group were likely a result of faster EMS response and transport times, which minimized out-of-hospital deaths. Factors prior to HEMS arrival may have more impact on the increased mortality rates of rural blunt trauma victims documented nationally.

Outcomes of blunt trauma victims transported by HEMS from rural and urban scenes.

OBJECTIVE: Mortality differences exist between victims of urban and rural trauma; however, it is unknown if these differences persist in those patients who survive to HEMS transport. This study examined the in-hospital mortality, length of hospital stay, and discharge status of adult blunt trauma victims transported by HEMS from rural and urban scenes to regional trauma centers. METHODS: Retrospective review of all adult (age >/= 15) HEMS transports in 2001; 271 urban and 141 rural blunt trauma patients were identified from HEMS transport records and the trauma registries at three level one trauma centers. Demographic data, scene and hospital interventions, as well as discharge status of the two groups were examined. RESULTS: Total mileage [27 +/- 12 vs. 119 +/- 64, p < 0.001], total flight times (minutes) [30 +/- 10 vs. 79 +/- 40, p < 0.001], and scene times (minutes) [16 +/- 8 vs. 21 +/- 14, p < 0.001] were significantly longer for rural flights. There were no significant differences between the groups with regard to age, gender, receiving hospital, and initial HEMS vitals. Injury Severity Score, ICU length of stay (LOS), total hospital LOS, and hospital mortality did not differ between the two groups. After controlling for age, gender, and ISS, there were no significant mortality differences between the two groups (p = 0.074). CONCLUSIONS: Despite longer flight and scene times for rural patients, adjusted in-hospital mortality rates were similar for patients transported from urban and rural scenes. Factors prior to HEMS arrival may contribute to increased mortality rates of rural blunt trauma victims documented nationally.

Scene transport of pediatric patients injured at winter resorts.

OBJECTIVE: To examine the characteristics of pediatric patients (age =16 years) injured at winter resort scenes and transported by helicopter emergency medical services (HEMS) or ground EMS (GEMS) ambulance services to regional trauma centers. METHODS: Between 1997 and 2001, a total of 119 patients (GEMS = 69; HEMS = 50) were identified from trauma registries and HEMS transport records. Demographic data, initial vital signs, hospital interventions, and discharge status of the two groups were examined. RESULTS: The distributions of gender, initial vital signs, Injury Severity Score (ISS; either = or > 15), intensive care unit (ICU) length of stay (LOS), total hospital LOS, and home discharge status were similar between the two groups (p = 0.05). Patients transported by HEMS were older (14 +/- 2 vs. 10 +/- 4, p < 0.001), less likely to be admitted to the hospital (73% vs. 98.5%; p < 0.001), and more likely to have multiple injuries [13 (27%) vs. 8 (11.6%), p = 0.032]. The GEMS patients had a higher rate of isolated extremity [33 (80.5%) vs. 8 (19.5%)] and thoracoabdominal [11 (73.3%) vs. 4 (26.7%)] injuries. The high orthopedic injury rate in the GEMS patients contributed to a higher rate of surgery in this group (45% vs. 24%, p = 0.028). Regardless of transport mode, patients requiring immediate interventions (intubation, chest tube placement, or blood product administration) had either a depressed level of consciousness (GCS = 12) on emergency department arrival or thoracoabdominal injuries. No deaths were recorded. CONCLUSIONS: Patients transported by HEMS and GEMS had similar hospital characteristics but different injury patterns. A prospective study examining the initial triage of pediatric patients injured at winter resorts would help to determine which subset of patients are best served by HEMS transport.

Transport of winter resort injuries to regional trauma centers.

INTRODUCTION: This study examined the epidemiology of winter resort injuries presenting to regional trauma centers by helicopter (HEMS) or ground (GEMS) ambulance. METHODS: Five hundred seventy-five patients (GEMS 289; HEMS 286) were identified from trauma registries and HEMS transport records. Demographic data, hospital interventions, and discharge status were examined. RESULTS: HEMS patients had a significantly lower Glasgow coma score (GCS) and trauma score (TS), longer intensive care unit (ICU) length of stay (LOS), and more deaths than did GEMS patients (P < 0.05). Despite this, significantly more HEMS patients were discharged home from the emergency department (24.5% vs. 4.8%; P < 0.001). HEMS patients had more isolated head/facial injuries and multiple injuries, with less isolated extremity injuries than did GEMS patients (P < 0.05). Regardless of transport mode, patients with multiple injuries, thoracoabdominal injuries, or head injuries with a GCS < or = 13 were more likely to require immediate interventions (intubation, chest tube, blood products). Patients with isolated extremity injuries rarely needed immediate care. CONCLUSION: HEMS patients had a higher acuity and different injury pattern when compared to GEMS patients. Approximately 24.5% of HEMS patients were discharged home from the ED. This reflects significant overtriage of patients to HEMS. A prospective study examining the initial triage of patients injured at winter resorts would help to determine which subset of patients are best served by HEMS transport.
