Life hazard ratio--a new scale for assessing the severity of injury in the populational stud.
The heterogeneous population of patients affected by trauma is extremely difficult to systematize. This is due to the diversity of mechanisms of injury, the nature and severity of the injury and the population, which relate to injuries, diverse in terms of gender, age, presence of comorbidities that make up the final severity of the injury and a certain degree of danger to life.


OBJECTIVE
To develop a universal method to assess the severity of injury and loss of life resulting from their consequences, using the parameters available in the Polish administrative databases, a similar diagnostic efficacy as other used scales to assess the severity of damage.


METHODS
The study analyzed a group of 92,463 patients hospitalized due to injuries sustained as a result of injuries in all hospitals of the Lublin region in 2003-2005. Developed catalogs risk factors, reference to the population of the Lublin province.


RESULTS
Developed five models predictive of injury severity scale counterparts, which include different combinations of risk factors associated with the type of injury, age of the patient and the mechanism of injury that have been evaluated for their diagnostic efficacy in differentiating the expected outcomes. Prediction model have the best diagnostic efficacy AUROC 0.9615, SE 0.0025 and 95% CI 0,9565-0,9665, hereinafter referred to as Life Hazard Ratio (LHR), which has a similarly high diagnostic efficacy as the other, examined in the work of the rock assess the severity of damage AUROC 0.9585, SE 0.0368, 95% CI0 0.8849-1.


CONCLUSIONS
1. The proposed method of use of the International Classification ICD-10 allows the use of regional administrative databases to conduct detailed analyzes of population and monitor trends in the epidemiology of injuries. 2. Developed Life Hazard Ratio (LHR)is a universal method for the objective evaluation of the severity of injuries and the associated risk of life-threatening, can also conduct population studies. 3. LHR has a comparable rate of diagnostic efficacy as other commonly used scales assessing the severity of the injury.
