The relevance of improving the quality of professional knowledge on suicidology in the medical environment is discussed. The authors note that the idea of suicide is usually associated with psychiatric care and in a wide range of cases raises when students go through a certain cycle, often with clearly insufficient attention to the problem. In graduate education programs, issues of suicidal prevention in an unjustifiably small volume are included in the specialties of "psychiatry", "narcology" and "psychotherapy". The knowledge of doctors of other "non-psychiatric" specialties usually does not exceed the college level, which limits their participation in preventive work, and leads to confusion when facing suicidal actions of their patients. Meanwhile, it is known that before their first attempt, many suiciders turn to interns about various diseases, but do not receive help. Subsequently, only no more than 5% of them continue treatment with a suicidologist (psychiatrist) upon discharge even if there is a crisis department in the structure of hospitals. One third commits another attempt within a year, which is predictable with insoluble (accumulating) psychosocial and, possibly, medical consequences of suicidal behavior (SB). In these conditions, the need for targeted training of primary care doctors (family doctors) is understandable. No less significant is the work with the staff of psychiatric hospitals (from psychiatrists, clinical psychologists to nurses and other personnel), who often have little knowledge of SB issues and often stigmatize patients and their relatives, which significantly limits the rehabilitation potential and the effectiveness of correctional work. In conclusion, the authors point out a number of important practical tasks in the education system: 1. The need for a systematic study and teaching of suicidology in medical universities with a rejection of the traditional dominance of a purely psychiatric approach, and its translation into the category of interdisciplinary scientific and practical problems. 2. The inclusion of suicidology in postgraduate programs, including taking into account the profile of trained doctors, and with an emphasis on developing practical skills in diagnosing suicidal behavior and management tactics for this category of patients. 3. The creation of textbooks, teaching aids on the prevention of suicide. Such an approach as a whole can serve as the basis for the formation of interdepartmental programs of suicidal prevention.
