National Assessment of Opportunities for Improvement in Preventable Trauma Deaths: A Mixed-Methods Study.

Trauma is a significant public health issue worldwide, particularly affecting economically active age groups. Quality management of trauma care at the national level is crucial to improve outcomes of major trauma. In Korea, a biennial nationwide survey on preventable trauma death rate is conducted. Based on the survey results, we analyzed opportunities for improving the trauma treatment process. Expert panels reviewed records of 8282 and 8482 trauma-related deaths in 2017 and 2019, respectively, identifying 258 and 160 cases in each year as preventable deaths. Opportunities for improvement were categorized into prehospital, interhospital, and hospital stages. Hemorrhage was the primary cause of death, followed by sepsis/multiorgan failure and central nervous system injury. Delayed hemostatic procedures and transfusions were common areas for improvement in hospital stage. Interhospital transfers experienced significant delays in arrival time. This study emphasizes the need to enhance trauma care by refining treatment techniques, centralizing patients in specialized facilities, and implementing comprehensive reviews and performance improvements throughout the patient transfer system. The findings offer valuable insights for addressing trauma care improvement from both clinical and systemic perspectives.

Trauma system establishment and outcome improvement: a retrospective national cohort study in South Korea.

Trauma is a major cause of mortality, disability, and health care costs worldwide. The establishment of a trauma system is known to solve these problems, but few studies have objectively evaluated the impact of a trauma system on outcomes. Since 2012, South Korea has established a national trauma system based on the implementation of 17 regional trauma centers nationwide and the improvement of the prehospital transfer system. This study aimed to measure the changes in performance and outcome according to the established national trauma system. In this national cohort-based, retrospective follow-up observational study, the authors calculated the preventable trauma death rate (PTDR) by conducting a multipanel review of patients who died in 2015, 2017, and 2019. Furthermore, the authors constructed a risk-adjusted mortality prediction model of 4767876 patients between 2015 and 2019 using the extended-International Classification of Disease Injury Severity Scores to compare outcomes. The PTDR was lower in 2019 than in 2015 (15.7 vs. 30.5, P <0.001) and 2017 (15.7 vs. 19.9%, P <0.001) representing 1247 additional lives saved in 2019 compared to that in 2015. In the risk-adjusted model, total trauma mortality was highest in 2015 at 0.56%, followed by that in 2016 and 2017 (0.50%), 2018 (0.51%), and 2019 (0.48%), revealing a significant decrease in mortality over the years ( P <0.001 for trend), representing nearly 800 additional lives saved. The number of deaths for more severe patients with a probability of survival less than 0.25 significantly decreased from 81.50% in 2015 to 66.17% in 2019 ( P <0.001). The authors observed a significant reduction in the PTDR and risk-adjusted trauma mortality in the 5-year follow-up since 2015 when the national trauma system was established. These findings could serve as a model for low-income and middle-income countries, where trauma systems are not yet established.

Comparison of Preventable Trauma Death Rates in Patients With Traumatic Brain Injury Before and After the Establishment of Regional Trauma Center: A Single Center Experience.

To compare preventable trauma death rates (PTDRs) in patients with traumatic brain injury before and after the establishment of a regional trauma center (RTC) at a single center. Our institution established an RTC in 2014. A total of 709 patients were enrolled from January 2011 to December 2013 (before RTC) and 672 from January 2019 to December 2021 (after RTC). The revised trauma score, injury severity score, and trauma and injury severity score (TRISS) were evaluated. Definitive preventable (DP), possibly preventable (PP), and non-preventable deaths were defined as TRISS >0.5, TRISS 0.25-0.5, and TRISS <0.25, respectively. PTDR was the proportion of deaths from DP+PP out of all deaths, and the preventable major trauma death rate (PMTDR) was the proportion of deaths from DP+PP out of all DP+PP. The overall mortality rates before and after the establishment of RTC were 20.3 and 13.1%, respectively. PTDR was lower after the establishment of RTC than before (90.3% vs. 79.5%). The PMTDR was also lower after the establishment of RTC than before (18.8% vs. 9.7%). The ratio of direct hospital visits was higher in patients before the establishment of RTC than in those after (74.9% vs. 61.3%, p<0.001). Establishing the RTC reduced PTDRs. Additional studies on factors associated with PTDR reduction are required.

Understanding Regional Trauma Centers and managing a trauma care system in South Korea: a systematic review.

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.

National trauma system establishment based on implementation of regional trauma centers improves outcomes of trauma care: A follow-up observational study in South Korea.

Although South Korea is a high-income country, its trauma system is comparable to low- and middle-income countries with high preventable trauma death rates of more than 30%. Since 2012, South Korea has established a national trauma system based on the implementation of regional trauma centers and improvement of the transfer system; this study aimed to evaluate its effectiveness. We compared the national preventable trauma death rates, transfer patterns, and outcomes between 2015 and 2017. The review of preventable trauma deaths was conducted by multiple panels, and a severity-adjusted logistic regression model was created to identify factors influencing the preventable trauma death rate. We also compared the number of trauma patients transferred to emergency medical institutions and mortality in models adjusted with injury severity scores. The preventable trauma death rate decreased from 2015 to 2017 (30.5% vs. 19.9%, p < 0.001). In the severity-adjusted model, the preventable trauma death risk had a lower odds ratio (0.68, 95% confidence interval: 0.53-0.87, p = 0.002) in 2017 than in 2015. Regional trauma centers received 1.6 times more severe cases in 2017 (according to the International Classification of Diseases Injury Severity Score [ICISS]; 23.1% vs. 36.5%). In the extended ICISS model, the overall trauma mortality decreased significantly from 2.1% (1008/47 806) to 1.9% (1062/55 057) (p = 0.041). The establishment of the national trauma system was associated with significant improvements in the performance and outcomes of trauma care. This was mainly because of the implementation of regional trauma centers and because more severe patients were transferred to regional trauma centers. This study might be a good model for low- and middle-income countries, which lack a trauma system.

National Follow-up Survey of Preventable Trauma Death Rate in Korea.

The preventable trauma death rate survey is a basic tool for the quality management of trauma treatment because it is a method that can intuitively evaluate the level of national trauma treatment. We conducted this study as a national biennial follow-up survey project and report the results of the review of the 2019 trauma death data in Korea. From January 1, 2019 to December 31, 2019, of a total of 8,482 trauma deaths throughout the country, 1,692 were sampled from 279 emergency medical institutions in Korea. All cases were evaluated for preventability of death and opportunities for improvement using a multidisciplinary panel review approach. The preventable trauma death rate was estimated to be 15.7%. Of these, 3.1% were judged definitive preventable deaths, and 12.7% were potentially preventable deaths. The odds ratio for preventable traumatic death was 2.56 times higher in transferred patients compared to that of patients who visited the final hospital directly. The group that died 1 hour after the accident had a statistically significantly higher probability of preventable death than that of the group that died within 1 hour after the accident. The preventable trauma death rate for trauma deaths in 2019 was 15.7%, which was 4.2%p lower than that in 2017. To improve the quality of trauma treatment, the transfer of severe trauma patients to trauma centers should be more focused.

Systematic Preventable Trauma Death Rate Survey to Establish the Region-based Inclusive Trauma System in a Representative Province of Korea.

BackgroundTrauma mortality review is the first step in assessing the quality of the trauma treatment system and provides an important basis for establishing a regional inclusive trauma system. This study aimed to obtain a reliable measure of the preventable trauma death rate in a single province in Korea.MethodsFrom January to December 2017, a total of 500 sample cases of trauma-related deaths from 64 hospitals in Gyeonggi Province were included. All cases were evaluated for preventability and opportunities for improvement using a multidisciplinary panel review approach.ResultsOverall, 337 cases were included in the calculation for the preventable trauma death rate. The preventable trauma death rate was estimated at 17.0%. The odds ratio was 3.97 folds higher for those who arrived within “1–3 hours” than those who arrived within “1 hour.” When the final treatment institution was not a regional trauma center, the odds ratio was 2.39 folds higher than that of a regional trauma center. The most significant stage of preventable trauma death was the hospital stage, during which 86.7% of the cases occurred, of which only 10.3% occurred in the regional trauma center, whereas preventable trauma death was more of a problem at emergency medical institutions.ConclusionThe preventable trauma death rate was slightly lower in this study than in previous studies, although several problems were noted during inter-hospital transfer; in the hospital stage, more problems were noted at emergency medical care facilities than at regional trauma centers. Further, several opportunities for improvements were discovered regarding bleeding control.

Treatment Experiences of Traumatic Brain Injury Patients using Doctor-Helicopter Emergency Medical Service: Early Data in a Regional Trauma Center.

ObjectiveThe purpose of this study is to analyze the results of doctor helicopter emergency medical service (HEMS) in traumatic brain injury (TBI) patients and to understand the effect and improvement of doctor HEMS.MethodsWe included TBI patients transferred by doctor HEMS of our hospital between February 2016 and December 2017. Basic characteristics, HEMS data, treatment and results data were analyzed retrospectively. We divided the patients into 3 groups as regarding severity of patient, relevance of treatment and transfer. We investigated the preventable trauma death rate (PTDR) of these groups to increase the reliability of the treatment outcome.ResultsTBI patients using doctor HEMS were indicated in 98 patients (18.7%) among 522 overall HEMS patients. The overall mortality was consisted in 21.4% and 43.2% was resulted in Glasgow outcome scale 4 or 5. The group of proper transport and treatment for severe TBI was consisted in 62.2% including 13 mortality cases and no preventable death. The group of delayed transport or treatment for severe TBI was 18.3% including 8 mortality cases and 1 preventable death. The PTDR of TBI after doctor HEMS was significantly lower than that of overall TBI (4.8% vs. 11.6%, p=0.045).ConclusionIn patients with severe TBI, doctor HEMS can improve treatment outcomes by reducing treatment delay and unnecessary examinations and this result was evidenced that the PTDR were decreased significantly after doctor HEMS transport. The appropriate treatment is mandatory for real-time communication with the emergency doctor and treatment preparation of the trauma team during the HEMS transport.

Preventable Trauma Death Rate after Establishing a National Trauma System in Korea

BackgroundThis study aimed to evaluate the current overall preventable trauma death rate (PTDR) in Korea and identify factors associated with preventable trauma death (PTD).MethodsThe target sample size for review was designed to be 1,131 deaths in 60 emergency medical institutions nationwide. The panels for the review comprised trauma specialists working at the regional trauma centers (RTCs); a total of 10 teams were formed. The PTDR and factors associated with PTD were analyzed statistically.ResultsOf the target cases, 943 were able to undergo panel review and be analyzed statistically. The PTDR was 30.5% (6.1% preventable and 24.4% possibly preventable). Those treated at a RTC showed a significantly lower PTDR than did those who were not (21.9% vs. 33.9%; P = 0.002). The PTDR was higher when patients were transferred from other hospitals than when they directly visited the last hospital (58.9% vs. 28.4%; P = 0.058; borderline significant). The PTDR increased gradually as the time from accident to death increased; a time of more than one day had a PTDR 14.99 times higher than when transferred within one hour (95% confidence interval, 4.68 to 47.98).ConclusionAlthough the PTDR in Korea is still high compared to that in developed countries, it was lower when the time spent from the accident to the death was shorter and the final destined institution was the RTC. To reduce PTDR, it is necessary to make an effort to transfer trauma patients to RTCs directly within an appropriate time.

Preventable trauma death rate in Daegu, South Korea.

ObjectiveThis study investigated the preventable death rate in Daegu, South Korea, and assessed affecting factors and preventable factors in order to improve the treatment of regional trauma patients.MethodsAll traumatic deaths between January 2012 and December 2012 in 5 hospitals in Daegu were analyzed by panel review, which were classified into preventable and non-preventable deaths. We determined the factors affecting trauma deaths and the preventable factors during trauma care.ResultsThere were overall 358 traumatic deaths during the study period. Two hundred thirty four patients were selected for the final analysis after excluding cases of death on arrival, delayed death, and unknown causes. The number of preventable death was 59 (25.2%), which was significantly associated with mode of arrival, presence of head injury, date, and time of injury. A multivariate analysis revealed that preventable death was more likely when patients were secondly transferred from another hospital, visited hospital during non-office hour, and did not have head injuries. The panel discovered 145 preventable factors, which showed that majority of factors occurred in emergency departments (49.0%), and were related with system process (76.6%).ConclusionThe preventable trauma death rate in Daegu was high, and mostly process-related.

Evaluation of Probability of Survival Using Trauma and Injury Severity Score Method in Severe Neurotrauma Patients

ObjectiveDespite several limitations, the Trauma Injury Severity Score (TRISS) is normally used to evaluate trauma systems. The aim of this study was to evaluate the preventable trauma death rate using the TRISS method in severe trauma patients with traumatic brain injury using our emergency department data.MethodsThe use of the TRISS formula has been suggested to consider definitively preventable death (DP); the deaths occurred with a probability of survival (Ps) higher than 0.50 and possible preventable death (PP); the deaths occurred with a Ps between 0.50 and 0.25. Deaths in patients with a calculated Ps of less than 0.25 is considered as no-preventable death (NP). A retrospective case review of deaths attributed to mechanical trauma occurring between January 1, 2011 and December 31, 2011 was conducted.ResultsA total of 565 consecutive severe trauma patients with ISS>15 or Revised Trauma Score<7 were admitted in our institute. We excluded a total of 24 patients from our analysis : 22 patients younger than 15 years, and 2 patients with burned injury. Of these, 221 patients with head injury were analyzed in the final study. One hundred eighty-two patients were in DP, 13 in PP and 24 in NP. The calculated predicted mortality rates were 11.13%, 59.04%, and 90.09%. The actual mortality rates were 12.64%, 61.547%, and 91.67%, respectively.ConclusionAlthough it needs to make some improvements, the present study showed that TRISS performed well in predicting survival of traumatic brain injured patients. Also, TRISS is relatively exact and acceptable compared with actual data, as a simple and time-saving method.

Trauma practice in Nigeria

Background: Trauma has assumed a pre-eminent epidemic proportion in the hierarchy of diseases afflicting the growing population of many developing countries including Nigeria competing with infections, cardiovascular diseases and cancers for attention and funding. The spectrum, quantum and future prospects of trauma and its practices have continued to expand but the response towards improving the current Nigerian situation is lagging behind. Objectives: To examine the current situation of trauma practice and the contribution of practitioners in the areas of research, training and community service in Nigeria and make suggestions for progress. Methodology: Electronic and manual bibliographic search was done using such words as trauma, injury, coupled with morbidity, mortality, death or fatality from publications across Nigeria. Personal contacts with colleagues for relevant papers were also done. Papers were reviewed for content, through the abstracts and all published works that provided information relevant to the objectives were read fully. Personal experience in the field was contributory. Results: Eight hundred and three abstracts were selected from the over 10,100 generated by the searches. Thirty four articles were contributed by colleagues and eleven were clearly used. Trauma from road traffic injuries and violence (gunshot, assault) constituted 40-90% of emergency room incidence with high rates in hospitals near highways. Autopsy reports confirmed road traffic injuries as commanding up to 80% of unnatural deaths in many teaching hospitals in Nigeria. There is no organized Emergency Medical Services but ambulance services are common in some cities. Many patients are largely transported by relations or bystanders when involved in trauma. Preventable Trauma Death rate is reportedly high, as much as 73.7% in one report. Conclusion: the spectre of trauma as an epidemic is receiving attention from practitioners and government but it is a far cry from what is needed. The spectrum is elongated in variety with the menace of motorcycle transport injuries overtaking other vehicle injuries in the some major cities and commanding an increasing prevalence in sub-urban areas. All health Institutions in Nigeria especially the Orthopaedic Hospitals and Federal Medical Centres need to improve on trauma research and publications just as the Nigeria Orthopaedic Association should intensify its championing of research efforts. A committee to evaluate and classify institutions on their level of trauma practice in order to guide referrals and sanction erring practitioners and establishments by complementing the Medical and Dental Council of Nigeria is desirable.

Preventable Pediatric Trauma Deaths in Ontario: A Comparative Population-Based Study

Previously, we demonstrated that 21% of pediatric (<16 years) trauma deaths in the Province of Ontario during the period 1985 to 1987 were potentially preventable. Since then many trauma system changes have occurred including field triage, designation of trauma centers, and improved injury prevention. This study aims to examine the current preventable trauma death rate in our system using identical methodology to our previous study. The records of all children (<16 years) who died in Ontario from 2001 to 2003 after blunt or penetrating trauma were obtained from the Chief Coroner and compared with those in our previous report. In both series, we excluded cases where care was not sought and all deaths due to asphyxia. Deaths were considered unpreventable if the Injury Severity Score, based on Abbreviated Injury Scale 1985, was >59; or if there was a head injury that received an Abbreviated Injury Scale score of 5 with the exception of isolated extra-axial hematomas. Eleven preventable deaths were identified. The preventable death rate was 7%, a significant decline from the 21% previously identified (p < 0.001; relative risk reduction for preventable death, 68% [95% confidence interval, 42-83%]; number needed to treat, 7). There has been a threefold decline in the preventable death rate, which we believe is related to improvements in the trauma system. We estimated that, for every seven deaths from fatal injuries, system changes between the two study periods eliminated one preventable death.

Preventable trauma death in Tehran: an estimate of trauma care quality in teaching hospitals.

The purpose of this study was estimate the number of preventable trauma deaths in teaching hospitals in Tehran. We evaluated the complete prehospital, hospital, and postmortem data of 70 trauma patients who had died during a 1-year period in two of the largest university hospitals in Tehran with a multidisciplinary panel of experts. Panel members identified 26% of all trauma deaths as preventable deaths. From 31 non-central nervous system-related deaths, 17 and 6 cases were identified as surely preventable and probably preventable, respectively. In central nervous system-related deaths, 5% of the deaths overall (2 of 38 cases) were identified as surely preventable or probably preventable. Sixty-four cases of medical errors were identified in 31 trauma deaths and 80% of these errors were directly related to the death of the patients. The high preventable trauma death rate in our teaching hospitals indicates that a relatively significant percentage of trauma fatalities could have been prevented by improving prehospital and in-hospital trauma care.
