Evaluation of emergency department admissions of mass casualty patients using the revised trauma score, injury severity score, and trauma and injury severity score.

BACKGROUND: There is a need for studies evaluating prognostic scoring systems in mass trauma patients in conflict regions to predict patient prognosis for emergency surgical prioritization. In this study, we aimed to evaluate scoring systems such as the Revised Trauma Score (RTS), Injury Severity Score (ISS), and Trauma and Injury Severity Score (TRISS) in trauma patients admitted due to mass trauma in Northern Syria. METHODS: This study was a retrospective evaluation of patients admitted due to mass trauma to the emergency departments of hospitals in Northern Syria. The diagnostic efficiency of RTS, ISS, and TRISS scoring systems was evaluated in these admissions in the first half of 2021. RESULTS: The most common causes of mass trauma were bomb blast (67.3%), gunshot (28.8%), and 14 (3.9%) patients admitted with other causes. When the odds ratio (OR) was analyzed, a one-unit increase in the RTS score increased the odds of survival by a factor of 6.133, and a one-unit increase in the TRISS score increased the odds of survival by a factor of 1.057. Differently, it was found that each 1-unit increase in ISS decreased the patient's probability of survival by 0.856 units. When RTS, TRISS, and ISS scores were analyzed, the area under the ROC curve was statistically significant for all of them (p<0.001) and all of them had a diagnostic value for mortality with sensitivities of 99.0%, 94.8%, and 91.9%; specificities of 87.8%, 90.5%, and 88.6; AUC of 0.958, 0.975, and 0.958, respectively. CONCLUSION: The use of trauma scoring systems, especially TRISS, may be useful for prioritizing patients in mass casualty settings in the presence of overcapacity.

Evaluation of prognostic scoring systems in patients hospitalized from the emergency department in a low-income region: northern Syria after internal turmoil as a different universe.

BACKGROUND: In low-income or underdeveloped countries with conflict and internal unrest, healthcare facilities and staff are limited. For these reasons, it is necessary to use the most straightforward scoring systems to ensure that health facilities and staff are used effectively and to expedite processes through early and effective interventions for patients. In this study, we evaluate and compare the scoring systems used to predict patient prognosis for Emergency Department (ED) patients in northern Syria, which is an area marred by conflict and internal unrest. METHODS: In this study, patients hospitalized in the Afrin, Azez Vatan, Jarablus, Tel Abyad, Rasulayn, El Bab, and Çobanbey hospitals in northern Syria were investigated. Only patients that were hospitalized in the emergency departments of these hospitals, including wards and intensive care units, were included in the study. Patients that were hospitalized from 03/01/2021 to 08/31/2021, the study period, were prospectively analyzed. Vital signs, medical histories and demographic data of the patients were recorded by calculating National Early Warning Score 2 (NEWS2), Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), and HOTEL Score (hypotension, oxygen saturation, low temperature, electrocardiogram, loss of independence). Acceptance parameters and scores were analyzed using statistical methods and by comparing groups. RESULTS: : All four scoring systems were found to be effective in predicting mortality regarding ROC curve analysis. However, the statistical significance of the RAPS was slightly stronger than that of the other scores and REMS had the highest sensitivity and specificity amongst the four systems, at 86.2% and 84.1%, respectively. Regarding the risk of hospitalization in the ICU (p < 0.05), the sensitivity values of the cut-off values offered by the scoring systems remained below 0.70 regarding ROC curve analysis. RAPS had the highest sensitivity (65.2%) of the four systems with a cut-off value of 1.5. DISCUSSION: This study in northern Syria has shown that although RAPS had stronger statistical power, REMS had better sensitivity and specificity for the prediction of mortality. Additionally, RAPS had better sensitivity for ICU risk. This study will contribute to the evaluation of healthcare in similar regions and to cost-effective healthcare delivery by using scoring systems for ED patients' admission.

Evaluation of clinical outcomes and comparison of prediction models in the burn population hospitalized from the emergency department: Can burn mortality scores be used in a post-conflict area such as northwest Syria?

BACKGROUND: Burns are a global health problem, especially in low- and middle-income countries. The use of models to predict mortality is more common in developed countries. In northern Syria, internal unrest has continued for 10 years. A lack of infrastruc-ture and difficult living conditions increase the incidence of burns. This study in northern Syria contributes to the predictions of health services provided in conflict regions. The first objective of this study specific to northwestern Syria was to assess and identify risk factors in the burn victim population hospitalized as emergencies. The second objective was to validate the three well-known burn mortality prediction scores to predict mortality: the Abbreviated Burn Severity Index (ABSI) score, Belgium Outcome of Burn Injury (BOBI) score, and revised Baux score. METHODS: This was a retrospective analysis of the database of patients admitted to the burn center in northwestern Syria. Patients who were admitted to the burn center as emergencies were included in the study. Bivariate logistic regression analysis was performed to compare the effectiveness of the three included burn assessment systems in determining the risk of patient death. RESULTS: A total of 300 burn patients were included in the study. Of them, 149 (49.7%) were treated in the ward, and 46 (15.3%) in the intensive care unit; 54 (18.0%) died, and 246 (82.0%) survived. The median revised Baux scores, BOBI scores, and ABSI scores of the deceased patients were significantly higher than those of the surviving patients (p=0.000). The cut-off values for the revised Baux, BOBI, and ABSI scores were set at 105.50, 4.50, and 10.50, respectively. For predicting mortality at these cut-off values, the revised Baux score had a sensitivity of 94.4% and a specificity of 91.9%, and the ABSI score had a sensitivity of 68.8% and a specificity of 99.6%. However, the cut-off value of the BOBI scale, calculated as 4.50, was found to be low (27.8%). The low sensitivity and negative predictive value of the BOBI model suggest that it was a weaker predictor of mortality than the others. CONCLUSION: The revised Baux score was successful in predicting burn prognosis in northwestern Syria, a post-conflict region. It is reasonable to assume that the use of such scoring systems will be beneficial in similar post-conflict regions where limited opportunities exist.

Awareness of damage control surgery and resuscitation practice: Rational emergency surgical trends in mass trauma events in Syria.

BACKGROUND: Mass trauma is an event in which the number of patients temporarily exceeds the capacity of medical personnel to provide optimal care. Looking at the global terrorism index, Syria is one of the most terrorism-affected countries in the Middle East, and the threat of terrorist attacks that can cause mass trauma persists. When it comes to dealing with mass trauma, the damage control approach has come to the forefront in recent years. In our study, we aimed to assess the awareness and training effectiveness of emergency physicians and surgeons on damage control surgery and resuscitation in Northwest Syria, where mass trauma due to terrorist attacks and social events is common. METHODS: A trauma team from Çobanbey Hospital in Northwest Syria conducted training on damage control and resuscitation. Syrian physicians who participated in this training were administered a damage control and resuscitation questionnaire before and after the training. RESULTS: A total of 43 subjects were enrolled in the study, and their mean age was 44.04±9.01 years. The majority of the physicians who participated in the training were from Elbab (23.3%), Afrin (23.3%), and Çobanbey (20.9%). The average work experience of the physicians was 14 years and the average number of non-elective surgeries performed in the last year was 47.5. While the average total score (pre-test) before the training was 67, the average total score (post-test) after the training increased to 72, and this difference was statistically significant (p=0.008). While the pre-test and post-test scores of those who were trained and had practiced placing intrathoracic clamp-wound clamp and trauma laparotomy were significantly higher than those who were not trained and had not used them (p<0.05), the difference between the pre-test and post-test scores of those who were not trained and had not used them was statistically significant (p<0.05). CONCLUSION: It is well known that there have been internal unrest and terrorist attacks in Northwest Syria for more than 10 years. It is important for physicians in this region to know the damage control strategies. In this regard, we have found that awareness among physicians has increased as a result of the training we have provided on damage control.
