Background: Although the relationship between cardiovascular and respiratory parameters and mortality in trauma patients has been reported in studies, the findings have been contradictory in many cases. Therefore, the present study aimed to evaluate the relationship of systolic and diastolic blood pressures, heart and respiratory rates, arterial oxygen saturation and shock index with 6-month mortality of trauma patients. Methods: In a prospective cohort study, vital signs of the trauma patients presenting to emergency department were evaluated on admission. The patients were followed for 6 months and mortalities were recorded. Finally, using stepwise multivariate logistic regression test and reporting odds ratio (OR) with 95% confidence interval (CI) and multilevel, random intercept logistic regression models, the relationship between the evaluated factors and probability of death was assessed. Results: Data of 3158 patients with the mean age of 31.47±16.37 years (73.65% male) were evaluated. Apart from heart rate, the relationship of all the factors with probability of death was non-linear. The slope of mortality risk remained relatively constant with increase in heart rate, which means that with increase in heart rate, the probability of death also increased linearly (R2=0.98; p |
