Case fatality rate and outcome in multiply injured patients after trauma: influence of specialisation from the first treating physician - an analysis of 198 patients from a national trauma centre

Abstract

The treatment of multiple injured patients is a highly demanding process concerning the amount and speed of gathered information. Physicians have to evaluate the situation and begin a treatment immediately. There may be influencing variables in the pre-clinical treatment which are correlated to the specialisation of the first treating physician and influencing the outcome of the patient. The aim of this study was to examine the influence of the specialisation of the first treating physician on the pre-clinical treatment and the resulting outcome. All trauma patients of our department from 2007 to 2010 who fulfilled the following criteria were included into our study: completely recorded DIVI-emergency protocol with declared specialisation of the first treating physician and inclusion into the trauma register of the DGU. This group of patients was divided into three groups according to the specialisation of the first treating physician (anaesthesia, surgery and other) and compared with one another. The study group consisted of 198 patients. 76 were treated by anaesthesiologists, 58 by surgeons, and 64 by physicians of other specialisations. The Injury Severity Score (ISS), the age and the distribution between the sexes showed no significant differences. Surgeons applied significantly less volume pre-clinically (794 ml [anesthesiologists: 1275 ml, others: 1231 ml; p value = 0.036]), the haemoglobin value was higher in the surgeon-treated group. This was also reflected in the applied blood transfusions at admission. The pre-clinical intubation rates (anaesthesiologists 48.7 %, others 37.5 %, surgeons 31 % [p value = 0.11]), the ventilator free days within the first 30 days after admission (anaesthesiologists 21.8, others 21.0, surgeons 25.8), intensive care unit free days within the first 30 days after admission (anaesthesiologists 18.4, others 18.5, surgeons 22.4) as well as the rescue time and case fatality rate showed no significant differences between the different groups. Multiply injured patients get a different treatment from the different specialised physicians in the pre-clinical phase. There were differences in the pre-clinical applied volume and haemoglobin value. Rescue time and intubation rate as well as outcome parameters were not statistically different. The case fatality rate in total was not significantly different between the 3 groups.
