Model of Decision Making Support for a Doctor in the Treatment of an Oncosurgical Patient in a Hospital.

At the present moment, there is no uniform approach to the decision to conduct a planned surgical intervention in case of oncosurgical pathology, with appropriate recommendations in different sources. Consequently, in modern medicine, there is a particular problem of an objective assessment of the patient's physical condition and a risk assessment of an upcoming surgical intervention for developing an individualized tactic of preparation for surgical treatment for each particular patient. The need for introduction of new approaches and technologies, as well as treatment regimens, that allow us to take a fresh look at the possibilities of solving the problems of predicting critical outcomes of planned operations, determined the purpose of our study. The result of our study was the design of a decision rule in the form of the Microsoft Access software, which allows to rank patients with oncological diseases by the probability of lethal outcome in surgery.
