[Decrease of the surgical risk level due to enhancement of the operative activity]

The surgical risk dynamics was studied up, basing on the scientific investigations data, performed during last 30 years. Basing on controversies existed in majority of aspects while performing the risk estimation calculation the need for the process to gain objective was established. The mathematical modelling procedure was proposed for the risk estimation. There were studied the influence of the surgeon qualification on the operative treatment volume and the result, as well as the surgeons of highest qualification occupation when the quantity of severely ill patients in emergency surgery enhances. The results, witnessing the reduction of the surgical risk factors influence while operative activity enhances, were adduced.
