Intentionally self-injured patients have lower mortality when treated at trauma centers versus non-trauma centers in South Korea

Objective

This study investigated the characteristics and survival rates of patients with intentional severe trauma (self-harm or suicide) who were transported to either a regional trauma center (TC) or a non-TC facility.

Methods

This retrospective, national, population-based, observational, case-control study included patients who sustained intentional severe trauma and had an abnormal Revised Trauma Score at the injury site between January 2018 and December 2019. The data were a community-based severe trauma survey based on data collected from severe injury and multiple casualty patients transported by 119 emergency medical services (EMS), distributed by the Korea Disease Control and Prevention Agency. The treatment hospitals were divided into two types, TC and non-TCs, and several variables, including in-hospital mortality, were compared. Propensity score matching (PSM) was used to mitigate the influence of confounding variables on the survival outcomes.

Results

Among the 3864 patients, 872 and 2992 visited TC and non-TC facilities, respectively. The injury severity did not differ significantly between patients treated at TCs and non-TCs (TC, 9; non-TC, 9; p=0.104). However, compared with those treated at non-TCs, patients treated at TCs had a higher rate of surgery or transcatheter arterial embolization (14.2% vs 38.4%; p<0.001) and a higher admission rate to the emergency department (34.4% vs 60.6%; p<0.001). After PSM, 872 patients from both groups were analyzed. Patients treated at TCs exhibited a higher overall survival rate than those treated at non-TCs (76.1% vs 66.9%; p<0.001), and multiple variable logistic regression analysis demonstrated that the causes of injury and transport to the TC were significantly associated.

Conclusion

Using Korean EMS data, the results of this study revealed that initial transport to TCs was associated with reduced mortality rates. However, considering the limitations of using data from only 2 years and the retrospective design, further research is warranted.

Relationships between trauma death, disability, and geographic factors: a systematic review

OBJECTIVE

Trauma is a global health problem. The causes of trauma-related deaths are diverse and may depend in part on socioeconomic and geographical factors; however, there have been few studies addressing such relationships. The aim of this study was to investigate the relationships between trauma and geographical factors in order to support policy recommendations to reduce trauma-related deaths and disability.

METHODS

In accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we searched international and Korean databases to retrieve relevant literature published between 2000 and 2020.

RESULTS

Thirty-two studies showed a positive relationship between the outcomes of major trauma and geographical factors. The study investigated regional factors including economic factors such as size of urban areas, gross domestic product, and poverty rate, as well as hospital parameters, such as presence of trauma centers and number of hospital beds. There was a tendency toward higher mortality rates in rural and low-income areas, and most of the studies reported that the presence of trauma centers reduced trauma-related mortality rates.

CONCLUSION

Our study showed that geographic factors influence trauma outcomes. The findings suggest geographical considerations be included in care plans to reduce death and disability caused by trauma.

Effects of job embeddedness and nursing working environment on turnover intention among trauma center nurses: A cross-sectional study

AIM

To investigate the effects of job embeddedness and nursing working environment on trauma center nurses' turnover intention.

BACKGROUND

Trauma center nurses have higher average turnover intention than hospital nurses. However, factors that increase the turnover intention of trauma center nurses remain unexplored.

METHODS

This cross-sectional study was conducted from August to October 2019, with 120 trauma center nurses working at three trauma centers in B, D, and U cities using measures of demographic characteristics, job embeddedness, nursing working environment, and turnover intention.

RESULTS

The mean turnover intention score was 3.60/5 points. There were significant correlations among turnover intention and fit, sacrifice, foundation for quality nursing, ability and leadership of nursing managers, cooperation of nurses and doctors, nurse participation in hospital management, and sufficient manpower and material support. Turnover intention was predicted by nurse participation in hospital management, gender, clinical experience, and fit, which explained 54%.

CONCLUSIONS

Factors that influence nurses' turnover intention at trauma centers were gender, clinical experience, job fit, and especially, nurses' participation in hospital management, which had the most effect on the nursing working environment.

IMPLICATIONS FOR NURSING MANAGEMENT

To expand participation of trauma center nurses, hospital management systems and organizational culture need improvement.

Implementation of Trauma Center and Massive Transfusion Protocol Improves Outcomes for Major Trauma Patients: A Study at a Single Institution in Korea

BACKGROUND

This study evaluated the effectiveness and clinical outcomes of the implementation of a trauma center and massive transfusion protocol (TCMTP) in a developing country without a well-established trauma system.

METHODS

We included patients (1) aged >15 years, (2) with an Injury Severity Score >15, (3) who received ≥10 units of packed red blood cells (PRBCs) within 24 h, (4) who directly visited our institution from 2010 to 2016, and (5) who survived for ≥24 h. Patients treated during the post-TCMTP period (2015-2016) were compared with historical groups treated pre-TCMTP (2010-2012) and interim-TCMTP (2013-2014). Demographics, transfusion and fluid therapy performance, and clinical outcomes were compared between the three groups.

RESULTS

Overall, 190 patients were included: 64, 64, and 62 patients in the pre-TCMTP, interim-TCMTP, and post-TCMTP groups, respectively. Comparison between the three groups revealed significant differences in the fresh-frozen plasma/PRBC ratio (p = 0.001) and crystalloid infusion (p = 0.007); these variables gradually increased from pre- to post-TCMTP. Conversely, colloid infusion showed a reduction post-TCMTP (p < 0.001). Kaplan-Meier curves revealed that the 90-day survival rate was significantly higher in the post-TCMTP group (pre-TCMTP: 45.3 vs. 75.8%, p = 0.001; interim-TCMTP: 56.3 vs. 75.8%, p = 0.027). In Cox regression hierarchical survival analysis, TCMTP showed a hazard ratio for mortality of 0.380 after adjusting for all potentially confounding factors.

CONCLUSIONS

Our results suggest that building trauma centers and establishing a massive transfusion protocol according to the specific situations of a country will help improve outcomes for major trauma patients, even in developing countries without a well-established trauma system.
