The criminal prosecution of medical workers for harm to the health of patients is currently one of the actively developed areas of work of the Investigative Committee. Investigators have a very vague idea about the peculiarities of the objects of evidence in this category of cases, which leads to an abundance of issues in the ruling, the resolution of which often does not allow achieving the goal of the investigation. This leads the issuance of new decisions and producing of many additional and repeated examinations. The passive position of the experts does not improve the situation either. The methodology for investigating cases of harm to the patient’s health by a doctor during the production of forensic medical examinations in criminal proceedings requires an expert to actively participate in establishing the circumstances to be proved. This methodology is proposed at the training cycle of the Department of Forensic Medicine of the Military Medical Academy named after V.I. C.M. Kirov. The article provides a previously unpublished generalized scheme of the algorithm that can be used in the production of forensic medical examinations in this category of cases.
