Purpose
Despite improvements in surgical technology, patients who undergo colorectal emergency surgery still have high mortality and complication rates. This places a high burden on the surgeons and the medical institutions who employ them. Mortality outcomes following emergency colorectal surgery were analyzed and risk factors associated with mortality were identified.
Methods
Data from patients who were admitted through the Emergency Room from June 2019 to December 2021 and underwent emergency colorectal surgery performed by a single surgeon were retrospectively analyzed. Surgical and medical records of various clinicopathological factors and the Mannheim peritonitis index (MPI) scores were compared between survivors and non-survivors.
Results
During the study period, 164 patients underwent colorectal emergency surgery. Following surgery, 24 patients (14.6%) died during their hospital stay. The American Society of Anesthesiologists Classification, the MPI score, indication of surgery, and comorbid disease were factors which showed statistically significant differences between the survivor and non-survivor groups. In particular, in the patients with an MPI score of ≥ 30, 22 of 49 deaths occurred.
Conclusion
Patients undergoing emergency colorectal surgery exhibit high postoperative mortality rates. By identifying these patients before surgery, and allocating appropriate surgical and intensive care resources to them, medical resources can be utilized more efficiently, and mortality rates can be reduced.

Purpose
Trauma is a common cause of death worldwide and head injury is the most common form of trauma presented at the Emergency Department. Physiological scores are better for predicting outcome than anatomical scores. To reduce mortality rates, this study compared the capacity of the revised trauma scores (RTS) and the Glasgow coma scale- age- pressure (GAP) scores to predict the survival of patients and effectively channel resources.
Methods
An observational study of head trauma patients aged 12 to 80 years was performed at a tertiary care center (N = 500). We noted demographic information, RTS and GAP trauma scores, and outcomes in terms of mortality or survival at 24 hours, 48 hours, and 7 days.
Results
Of the 500 patients who were enrolled, 414 (82.8%) survived 24 hours, 373 (74.6%) survived 48 hours, and 265 (53%) survived after 7 days. Using the Receiver Operating Characteristic curve, the RTS score was a significantly better predictor of survival in patients with head trauma than the GAP score at 24 hours (p = 0.044) and 48 hours (p = 0.049) of admission. The results were not significantly different at 7 days (p = 0.240). Mortality or survival outcomes were not significantly different between the RTS and GAP scores (p = 0.373).
Conclusion
RTS appears to be a better early predictor for mortality (within 48 hours of admission) than the GAP score. The RTS was more effective in directing the triage of patients which improved survival rates in head trauma patients.

Purpose
We sought to assess mortality trends in chest-abdominal trauma patients, before and after the implementation of the Project Supporting Establishment of Trauma Centers (PSETC) in the Republic of Korea.
Methods
Data from the National Health Insurance Service claims database between 2009 to 2017 were analyzed. Patients with chest-abdominal trauma were defined as those with relevant main diagnosis codes and claims for emergency medical management fees. Mortality and cumulative data were analyzed for each year to compare mortality before and after the establishment of regional trauma centers across Korea (2014).
Results
In total, 29,127 patients were included in the analysis. While the annual incidence of trauma-related chest-abdominal injuries increased, mortalities decreased. In particular, the trauma incidence rate among patients over 50 years increased during the study period. Mortalities at trauma centers did not change year by year after the PSETC. Before and after 2014, when trauma centers operated under the PSETC, mortalities decreased [trauma cases before the PSETC; n = 14,321 (mortality 5.61), after the PSETC; n = 14,806 (mortality 4.96)].
Conclusion
The number of patients treated for chest-abdominal injuries increased from 2009 to 2017 in Korea, whereas mortalities decreased over the same period.

Purpose
A nationwide study (2012-2017) of preventable trauma death rates (PTDR) showed a 15.3% decrease after Regional Trauma centers were initiated. However, in non-trauma centers with an Emergency Department there is limited data of preventable mortality in trauma patients. Therefore, the purpose of this retrospective study was to investigate preventable mortality in trauma patients in a nonregional trauma center and determine the effect of initiating a Trauma Team.
Methods
There were 46 deaths of trauma patients recorded in the National Health Insurance service Ilsan Hospital (NHISIH) in South Korea from January 2019 to December 2021. These patients’ preventable deaths were analyzed by an expert panel review considering the implementation of the Trauma Team in April 2020.
Results
All deaths were attributable to blunt trauma with an average Injury Severity Score of 26.0 ± 19.2, Revised Trauma Score of 5.05 ± 3.20 and Trauma and Injury Score of 56.6 ± 41.3. The most frequent cause of death was traumatic brain injury followed by respiratory arrest. The most frequent error was delayed transfusion followed by delayed treatment of bleeding. Treatment errors occurred the most in the Emergency Room followed by the Intensive Care Unit. The PTDR of patients before the involvement of a Trauma Team (January 2019 to March 2020) and after the Trauma Team was initiated in April 2020 decreased from 27.27% to 4.27%, respectively (p = 0.021).
Conclusion
The introduction of a dedicated Trauma Team in a non-regional trauma center significantly reduced the overall PTDR in trauma patients.

Purpose
This study aimed to investigate the characteristics of elderly patients who visited a non-regional trauma center to examine the effects of old age on the clinical outcomes of patients.
Methods
The medical charts of 159 patients with trauma who visited the National Health Insurance Service Ilsan Hospital between March 2020 and February 2022 were retrospectively analyzed.
Results
Of the 159 patients, 41 were assigned to the elderly patient group (EPG) and 118 were assigned to the non-elderly patient group (NEPG). The average age of patients in each group was 75.5 and 38.2 years in the EPG and the NEPG, respectively. Comparing the injury mechanism between the two groups, pedestrian traffic accidents (TA) were the most common (24.4%), followed by slipping (19.5%), motorcycle TA, and bicycle TA (14.6%) in EPG. In the NEPG, motorcycle TA (28.0%) was the most common, followed by car TA (27.1%), and fall injury (16.9%), with a significant difference between the two groups (p < 0.001). The significant differences between the two groups were the injury severity score (ISS; p = 0.004), severe trauma (p = 0.045), intensive care unit admission (p = 0.028), emergency operation (p = 0.034), and mortality (p = 0.013). The statistically significant risk factors for mortality were old age (p = 0.024) and chest injury (p = 0.013).
Conclusion
Patients in the EPG compared with the NEPG group showed different injury mechanisms. The EPG has a higher severity and mortality rate than the NEPG.

Purpose
To evaluate the risk factors associated with 30-day mortality in patients with postoperative acute kidney injury who underwent continuous renal replacement therapy (CRRT).
Methods
Retrospective analysis of the medical charts of patients with postoperative acute kidney injury who underwent CRRT in the intensive care unit between April 2012 and May 2019 was conducted.
Results
There were 71 patients whose average age was 64.8 years, and average Acute Physiology and Chronic Health Evaluation 2 score was 26.2. There were 37 patients who had non-trauma emergency surgery, 16 who required trauma surgery, and 18 who had elective major surgery. In most patients, CRRT was started based on Stage 3 Acute Kidney Injury Network criteria, and the mean creatinine level at the time of CRRT initiation (3.62 mg/dL). The median period from surgery to CRRT was 3 days, and the median CRRT application was 4 days. Forty-seven patients died within 30 days of receiving CRRT. Age, elective major surgery, creatinine level on initiation of CRRT, use of norepinephrine upon the initiation of CRRT, and average daily fluid balance/body weight for 3 days following the initiation of CRRT were associated with increasing 30-day mortality in univariate analysis. In multivariate analysis, age, major elective surgery, and norepinephrine use upon initiation of CRRT were identified as independent risk factors for 30-day mortality.
Conclusion
Surgical patients who underwent CRRT postoperatively had a poor prognosis. The risk of death in elderly patients who have undergone major elective surgery, or are receiving norepinephrine upon initiation of CRRT should be considered.

Purpose
The relationship between the timing of admission (work-hours or after-hours) to the intensive care unit (ICU) and mortality among surgical ICU (SICU) patients is unclear. This study aimed to investigate whether admission to SICU during after-hours was associated with in-hospital mortality.
Methods
This retrospective cohort study was conducted in a tertiary academic hospital. The data of 571 patients who were admitted to the SICU and whose complete medical records were available were analyzed. Work-hours were defined as 07:00 to 19:00 Monday to Friday, during which the ICU was staffed with intensivists. After-hours were defined as any other time during which the SICU was not staffed with intensivists. The primary outcome measure was in-hospital mortality according to the time of admission (work-hours or after-hours) to the SICU.
Results
A total of 333 patients, were admitted to the SICU during work-hours, and 238 patients after-hours. Unplanned admissions (47.1% vs. 33.3%, p < 0.001), acute physiology and chronic health evaluation II score ≥ 25 (23.9% vs. 11.1%, p < 0.001), the need for ventilator support (34.0% vs. 17.4%, p < 0.001), and the use of vasopressors (50.0% vs. 33.3%, p < 0.001) were significantly higher in the after-hours group compared with the work-hours group. Multivariate analyses revealed that the timing of SICU admission was an independent predictor of in-hospital mortality (odds ratio, 2.526; 95% confidence interval, 1.010–6.320; p = 0.048).
Conclusion
This study showed that admission to the SICU during after-hours was associated with increased in-hospital mortality.

Purpose
A review was performed to determine the frequency of activating medical emergency teams (MET) in surgical wards, so that resource allocation could be optimized.
Methods
A retrospective observational study was performed to determine the time and frequency when MET were deployed (N = 465) to patients (n = 387) who were admitted to the surgical ward, from March 2013 to July 2016 due to emergency situations.
Results
Of the 465 MET activations, 8 did not incur any further intervention. The review showed an average of 151 minutes from onset of symptoms to MET activation, and an average of 110 minutes until intervention (additional diagnosis / treatment). The number of MET activations increased year by year from 2013 to 2016. The transfer of patients to the intensive care units also increased from 34 in 2013, to 82 in 2016. The lowest number of MET activations occurred between 04:00 and 05:00, but there was no difference in the number of MET activations between day and night. However, MET activation in response to acute respiratory distress was significantly higher during the nighttime (p = 0.003).
Conclusion
Patients admitted to a surgical ward have more serious complications. This study showed that the use of MET in surgical wards has increased year by year, and the frequency of calls between day and night was not different, except higher MET activations observed at night in patients with acute respiratory distress.

Purpose:

The aim of this study is to evaluate treatment outcomes and mortality risks associated with hemodynamic instability caused by severe pelvic fracture in a regional trauma center.

Methods:

The medical charts of 44 patients with hemodynamic instability due to pelvic fractures who were admitted to a regional trauma center from January 2014 to May 2017 were analyzed retrospectively.

Results:

The mean age was 61.8 years, and the mean injury severity score was 39.1. Twenty-six patients (59.1%) were transferred from other hospitals, and the median time from injury to emergency room arrival was 115.5 minutes. Preperitoneal pelvic packing, pelvic angiography, and external pelvic fixation were performed in 38 patients (86.4%) for hemostasis. The mortality rate was 52.3%, and 15 patients (34.1%) died from hemorrhage. Logistic regression analysis showed that initial low systolic blood pressure and packed red blood cell (PRBC) requirement were independent risk factors associated with mortality. PRBC requirement for four hours and application of emergent hemostatic procedures were independent factors associated with hemorrhage-induced mortality.

Conclusion:

Emergency procedures for hemostasis should be performed immediately for patients with hemodynamic instability due to pelvic fracture, and they should be transferred to a regional trauma center as soon as possible.
