Comorbidity as the coexistence of two and/or more syndromes or diseases that are pathogenetically interrelated or coincide in time in one patient, regardless of the activity of each of them, is widely represented among patients admitted to therapeutic hospitals. At the stage of primary health care, patients with multiple diseases at the same time are the rule rather than the exception. According to M.. Fortin, based on the analysis of 980 medical records taken from the daily practice of a family doctor, the prevalence of comorbidity ranges from 69% in young patients(18-44years) to 93% in middle-aged people (45-64 years). andup to 98% – in patients of the older age group (under 65 years of age). At the same time, the number of chronic diseases varies from 2.8 in young patients to 6.4 in old people (M.. Fortin, 2005) .In this paper, the author points out that the basic research of medical documentation aimed at studying the prevalence of comorbidity and identifying its structure was carried out before the 90s of the last century.
