Difficulties in the timely identification of the source of gastrointestinal bleeding affect the outcome and quality of medical care provided to patients with a surgical profile.

Development of an algorithm for differential diagnosis of gastrointestinal bleeding using the methods of mathematical statistics.

A multilevel algorithm for diagnosing patients with gastrointestinal bleeding is presented, the accuracy of which is 88-98%. The resulting rules include parameters that determine the clinic, localization and severity of gastrointestinal bleeding (21 parameters in total).

The created rules can be introduced into medical information systems of medical organizations to clinical decision support by medical specialists of surgical and gastroenterological profiles.
