title: Comparison of the RTS and ISS scores on prediction of survival chances in multiple trauma patients.
abstract: OBJECTIVE
  Trauma represents the third cause of death after cardio vascular disease and tumors. Also in Iran, road accidents are one of the leading causes of death. Rapid evaluation of trauma severity and prediction of prognosis and mortality rate and probability of survival and rapid treatment of patients is necessary. One of the useful instruments for this is ISS and RTS scoring systems. This study evaluated 70 multi trauma patients in Fatemi trauma center affiliated to Ardabil University of medical science.
  
  
  METHODS
  This study was prospective study populations were 70 trauma patients admitted in Fatemi trauma center. During the II month, and patients data was collected by clinical evaluating of patients and follow up them and arranged as a questionnaire then related findings were evaluated by SPSS software.
  
  
  RESULTS
  The average age of patients was 37.6±23.5 years and minimum and maximum age was 1 and 85 years. The most common involved group was 10-19 years (13 men and 1 woman). 81.4% of patients (57 cases were male) and 18.6% were female (13 cases). The most common causes of trauma was car accident with 64.2% frequency (43 cases) and then motorcycle accident with 16.4% frequency (11 cases) and all injured patient due to motorcycle accident compose the age group less than 40 years old. Also car accident had the highest frequency in both gender. Other causes of trauma were fall down with 13.5% frequency (9 cases) and under debris 5.9% (4 cases). Also from 70 studied patients, 67 cases (95.7%) had blunt trauma and 3 cases (4.3%) had penetrating trauma. The most penetrating trauma occurs in ages less than 50 years and was in the range of 30-50 years. The average RTS and ISS was 10.67±1.45 and 18.11±8.64, high and low scores of ISS existed in all age groups but a low score of RTS was highest in the children age group. The average length of ICU stay was 12.14±11.11 days. Overall mortality was 15.7 (11 cases). In this study, by the ISS increasing, the mortality rate also increased. But there is no relation between the mortality rate and RTS ratio.
  
  
  CONCLUSIONS
  The ISS scoring system performed better than the RTS in predicting of mortality and probability of survival and the length of ICU stay and had high accuracy and can predict patients' outcome better by ISS measuring.
