Objective. The impact of a multidisciplinary quality management system (MQMS) on the early treatment of severely injured patients was tested.
Design and setting. Prospective clinical study in two level 1 trauma centers.
Methods and materials. MQMS comprised a protocol for documentation, 20 assessment criteria, and the judgement of data by a quality circle. After implementation in Munich (1st period, n=90; 2nd period, n=77) the validation took place in Essen (1st period, n=175; 2nd period, n=150).
Results. Improvements in diagnostics were shown by significant time savings in radiological diagnostics and before computed tomography in severe traumatic brain injury. In patients with hemorrhagic shock there was a reduction in time before transfusion (49 to 14 min in Munich; 31 to 22 min in Essen) and before emergency operation (74 to 43 min in Munich; 69 to 45 min in Essen). The time before craniotomy was reduced from 97 to 67 min in Munich. The incidence of delayed diagnosis of life-threatening lesions was diminished from 6% to 3% in Munich (not found in Essen). The TRISS technique showed a reduction in mortality in both hospitals in the second period (Munich: 15.4% TRISS vs. 9.1% observed mortality; Essen: 17.8% vs. 11.3%).
Conclusions. MQMS improved early clinical treatment in severe injury with respect to therapeutic effectiveness and outcome. The effectiveness of the MQMS was shown at two different hospitals
