Impact of interhospital transfer on outcomes for trauma patients: impact of direct versus non-direct transfer

OBJECTIVE: This study compared the prognosis of patients who visited the trauma center directly (direct visit group) with those transferred from the non-trauma center (transferred group). METHODS: The patients, who were 18 or older with Injury Severity Score of 15 or more in the trauma center at Busan, were studied from October 2015 to October 2016. To compare the treatment time between the direct visit and transferred group, first treatment time, final treatment time, and time to visit the trauma center were examined. To compare the prognosis, this study compared the 48-hour, 7-day, and in-hospital mortality rate as well as the duration of intensive care unit (ICU) and total hospital stay. To analyze the factors affecting the outcome of transferred group, the physician's level and procedures that had been performed at the non-trauma center were examined. RESULTS: The mortality was similar in the direct visit and transferred group (48-hour 7.6% vs. 4.6%, P=0.111; 7-day 11.1% vs. 7.2%, P=0.89; and in-hospital 14.6% vs. 11.3%, P=0.214). The length of ICU and total hospital stay were similar in the two groups. The mortality was higher in the patients in the transferred group when using intubation, transfusion, and pressure intensifier. The intubated patients showed higher mortality according to logistic regression. CONCLUSION: The mortality, length of ICU, and hospital stay were similar but the time to visit the trauma center and the final treatment time were longer in transferred group. Stabilizing the patient at the near non-trauma center may be more helpful for some patients.

Validity of the Newly Developed Five Level Pediatric Triage System Implemented in a Children's Hospital Emergency Department

PURPOSE: Korean Acuity and Triage Scale (KTAS) has been used nationally since 2016 for triage in emergency departments. After the newly developed triage tool was applied, there have been few studies of the validity of pediatric KTAS. The purpose of this study was to evaluate the validity of KTAS in children under the age of 15 who visited a single children's hospital. METHODS: This retrospective study was conducted on 7,011 pediatric patients under the age of 15 who visited a single child hospital between January 1 and December 31, 2016, the difference in the admission rate, intensive care unit admission rate, length of stay in the emergency department, and total hospital cost in emergency department were analyzed using the KTAS level. RESULTS: The number of patients triaged as KTAS IV was highest with 48.2%. The length of stay was longest in KTAS I and shortest in KTAS V. The medical cost in emergency department was highest in KTAS I and lowest in KTAS V. All dependent variables except for the intensive care unit admission rate showed significant differences according to the KTAS level. CONCLUSION: When the KTAS of the newly developed five level triage system was applied to pediatric patients, there were statistically significant difference in hospitalization, length of stay in emergency department, and total cost to the emergency department according to the KTAS level. Therefore, it will be necessary to evaluate the validity of KTAS through multicenter studies including hospitals with various characteristics.
