This study examined emergency medical service (EMS) transportation patterns for adult trauma patients before and after establishing a level 1 regional trauma center (RTC) and to evaluate the transportation approach after prehospital severity screening.


This was a retrospective observational study of trauma patients aged ≥18 years admitted via EMS to the emergency department or a level 1 RTC, 1 year before to 3 years after RTC establishment. Patients with an Injury Severity Score (ISS) in the patient registration system were selected. Analyses were performed to determine transportation pattern changes by comparing patients pre- and post-RTC establishment and by yearly comparisons over the 4-year study period using the Mann-Whitney U test and chi-square test.


Overall, 3,587 patients were included. The mean ISS was higher in the post-RTC group (n=2,693; 10.63±8.90, median 9.00) than in the pre-RTC group (n=894; 9.44±8.20, median 8.00; p<0.001). The mean transportation distance (9.84±13.71, median 5.80 vs. 13.12±16.15 km, median 6.00; p<0.001) was longer in the post-RTC group than in the pre-RTC group. Furthermore, proportionally fewer patients were transported from an area in the same city as the RTC after establishment (86.1% vs. 78.3%; p<0.001). Yearly comparisons revealed a gradually increasing trend in the hospital death rate (ptrend=0.031).


After establishing a level 1 RTC, the EMS transportation of severe trauma patients increased gradually along with the long-distance transportation of minor trauma patients. Therefore, improved prehospital EMS trauma severity assessments and level 1 RTC involvement in patient classification in the prehospital phase are necessary.

AbstractAbstract PDF
Detection and determination of tendon injury in the finger or hand is not easy. Therefore, we aimed to study and evaluate the accuracy and the effectiveness of ultrasonography for the diagnosis of finger tendon injury.
In this study, we enrolled patients, regardless of age and sex, with lacerations on their fingers. Patients with invisible wounds were excluded. We evaluated the accuracy and the effectiveness of ultrasonography and compared the results obtained from ultrasonography and with those obtained by visual observation of the injuries.
The sensitivity, the specificity and the accuracy of ultrasonography were found to be 66.7%, 100% and 91.3%, respectively (p<0.001) while those of physical examination were 71.4%, 98.3% and 91.3%, respectively. Small differences were observed between the sensitivities and specificities of the two examinations; however, the accuracies were the same (p<0.001). The area under the receiver operating characteristic (ROC) curve, which was used for diagnosis of tendon rupture using ultrasonography, was found to be 0.985 (95% confidence interval CI: 0.929-0.999),while that of physical examination was 0.938 (95% CI: 0.861-0.980).
Ultrasonography can be used an effective diagnostic tool for patients with finger tendon injury.

AbstractAbstract PDF
This hospital has operated a trauma system of the inclusive trauma system under the sponsorship of this hospital and with financial support from the government from 2011, and it has been designated as a specialized trauma center (candidate) since November 2008. Therefore, this emergency medical center evaluated the influence of the inclusive trauma system on the course of healing and on the results for trauma patients within the region.
The medical records of all patients who were registered as trauma patients from among those who visited the emergency medical center of this hospital from April 2009 to May 2012 were retrospectively reviewed. The monthly and the annual averages of important indices, such as the time in the emergency room and preventable mortalities, were calculated, and patterns of change were sought. The preventable mortality rate was calculated by using the Trauma Injury Severity Score (TRISS) for each patient.
The total number of patients registered from April 2009 to May 2012 was 601, and male patients accounted for a larger proportion(432 males(71.88%) vs. 169 females(28.12%)). Their average age was 46.2 years, the average Revised Trauma Score (RTS) was 5.74 points, and the average Injury Severity Score (ISS) was 26.99 points. The preventable mortality rate during the entire period, which was calculated using the TRISS, appeared lower than the preventable mortality rates reported in past studies in the Republic of Korea.
These results for the operation of a new trauma system are limited in that they are only for a local private university hospital. However, results show greater changes and developments in and out of the hospital due to multilateral endeavors by the trauma team and the hospital. These endeavors include increased communications among the departments and development of a complementary patient registration system.
