Purpose:
Timely surgical intervention is crucial in trauma care, particularly in patients with hypotensive abdominal injuries.In South Korea, the regional trauma center system has adopted a quality metric mandating initiation of emergency surgery within 1 hour of emergency department (ED) arrival for such patients. We evaluated the impact of ED-to-surgery time on clinical outcomes in hypotensive abdominal trauma and assessed the appropriateness of the 1-hour threshold.
Methods:
This multicenter retrospective study included 425 trauma patients who underwent emergency abdominal surgery at 2 regional trauma centers between 2019 and 2022. Patients with an initial or lowest recorded systolic blood pressure (SBP) <90 mmHg were included. The primary outcome was in-hospital mortality; secondary outcomes included complications, intensive care unit stay, and total hospital stay. Patients were categorized into early (≤1 hour) and delayed (>1 hour) surgery groups. Statistical analyses included logistic regression, propensity score matching (PSM), receiver operating characteristic curve, and complication analysis by 30-minute intervals.
Results:
We found that 243 patients (57.2%) underwent surgery within 1 hour. In-hospital mortality did not differ significantly between early and delayed groups. Age, Glasgow Coma Scale, lowest SBP, 4-hour RBC transfusion volume, and abdominal Abbreviated Injury Scale were independent mortality predictors. PSM confirmed no mortality difference by surgical timing. However, complication rates increased with surgical delays.
Conclusion
While surgical delay was not associated with mortality, it was linked to increased complications. Future trauma quality metrics should incorporate refined patient stratification and evaluate the entire process aimed at restoring physiological instability, rather than relying on a strict 1-hour threshold.

Purpose:
We investigated the clinical features, current negative-pressure wound therapy (NPWT) management strategies, and outcomes of pelvic-perineal soft tissue infection after open pelvic fractures.
Materials and Methods:
We analyzed the data of patients admitted to our trauma center with pelvic-perineal soft tissue after open pelvic fractures over a 7-year period. We investigated the injury severity score (ISS), medical costs, number of NPWTs, time required to reach definite wound coverage, complications, fracture classifications, transfusion requirements, interventions, length of stay (LOS) in hospital and intensive care unit (ICU), and prognosis.
Results:
Twenty patients with open pelvic fractures were treated with NPWT, and one patient who underwent NPWT died of pelvic sepsis during ICU treatment. The median LOS in hospital and medical costs were 98 [56–164] days and 106400 [65600–171100] USD, respectively. Patients treated with instillation NPWT (iNPWT, n=10) had a shorter NPWT duration (24 [13–39] vs. 46 [42–91] days, p=0.023), time to definite wound coverage (30 [21–43] vs. 49 [42–93] days, p=0.026), and hospital LOS (56 [43–72] vs. 158 [101–192] days, p=0.001), as well as lower medical costs (67800 [42500–102500] vs. 144200 [110400–236000] USD, p=0.009) compared to those treated with conventional NPWT.
Conclusion
NPWT is a feasible method for treating pelvic soft tissue infections in patients with open pelvic fractures. iNPWT can reduce the duration of NPWT, hospital LOS, and medical costs.

Annals of Surgical Treatment and Research 2024;107(5):274-283
Purpose:
There is a high possibility of trauma patients being referred to an unsuitable medical institution for their rehabilitation treatment since the decision is made by them. This study sought to develop a standardized scale to evaluate the need for specialized rehabilitation in patients with multiple traumas and evaluate the effectiveness of the developed scale.
Methods:
This study employed a systematic review of existing literature to inform the development of a specialized rehabilitation evaluation scale. An expert panel consisting of trauma surgeons, orthopedic surgeons, and rehabilitation medicine physicians collaborated to create a discharge-planning checklist by assessing the need for specialized rehabilitation. The checklist was validated using retrospective data from trauma patients treated at Seoul National University Hospital.
Results:
We identified 12 studies, providing factors influencing the discharge location and rehabilitation needs of trauma patients. The checklist was developed through expert consensus and comprised 3 criteria: discharge feasibility to specialized rehabilitation facilities, diagnostic eligibility for specialized rehabilitation, and functional assessment. Validation of the checklist demonstrated that the percentage agreement, likelihood ratio of a positive test, and Cohen’s kappa value were 82.1%, 5.21, and 0.375, respectively when comparing whether the checklist was met and the actual discharge location, indicating its effectiveness.
Conclusion
This study established standardized criteria for assessing the need for specialized rehabilitation in trauma patients, offering a practical tool for clinical use. Implementation of this assessment scale has the potential to improve the trajectory of trauma survivors by facilitating access to appropriate rehabilitation services.

The Korean government initiated a plan to designate and establish Regional Trauma Centers to reduce the preventable trauma death rate to <20% so as to be on par with advanced countries by 2020. This initiative was undertaken because the reported preventable trauma death rate was close to 40% in South Korea from 1997 to 2009. This review aimed to provide an overview of these Regional Trauma Centers and discuss further development of the trauma care system to assess its performance. As of September 2021, 15 Regional Trauma Centers had been established through a metropolitan-based designation process. Each center has been equipped with Level-I facilities. These Regional Trauma Centers have had 2 positive effects; namely, an increase in the number of severely injured patients attending these centers and a decrease in the national preventable trauma death rate from 30.5% in 2015 to 19.9% in 2017. The establishment of Regional Trauma Centers can lead to improved performance, maximal efficiency, and reduction of preventable deaths in trauma patients.They can also play a key role in prehospital triage and transportation in the trauma care system.
