PREHOSPITAL CARE OF BURN PATIENTS AND TRAJECTORIES ON SURVIVAL

We sought to identify factors associated with the prognosis and survival of burn patients by analyzing data related to the prehospital treatment of burn patients transferred directly to the burn unit from the accident site. We also aimed to assess the role of prehospital physicians and paramedics providing care to major burn patients. This study included adult burn patients with severe burns treated between 2006 and 2010. Prehospital patient records and clinical data collected during treatment were analyzed, and the Injury Severity Scale (ISS) was calculated. Patients were grouped into two cohorts based on the presence or absence of a physician during the prehospital phase. Data were analyzed with reference to survival by multivariable regression model. Specific inclusion criteria resulted in a sample of 67 patients. The groups were comparable with regard to age, gender, and injury etiology. Patients treated by prehospital physicians (group 1, n=49) were more severely injured than patients treated by paramedics (group 2, n=18) in terms of total burn surface area (%TBSA) (32% vs. 17%, p=0.033), ISS (25vs. 8, p < 0.000), and inhalation injuries (51% vs. 16%, p=0.013), and presented with a higher pulse rate, lower systolic blood pressure, and lower median pH. Age, gender, %TBSA, and ISS were significantly associated with survival in both groups. Survival at 30days was associated with age, gender, the amount of intravenous fluids (in liters) received during the first 24hours, and the final %TBSA. Variables found to be independently associated by multivariable regression model with 30day mortality were age, female gender, and final TBSA. We identified prehospital prognostic factors affecting patient outcomes. Based on the results from this study, our current EMS system is capable of identifying seriously injured burn patients who may benefit from physician attendance at the injury scene.
