In this study we retrospectively analyzed the structure of admission and the character of urgent pathology among patients with newly diagnosed cases of HIV infections in the specialized clinical departments of Sklifosovsky Research Institute for Emergency Medicine (RIEM). For the period from 2008 to 2015 it was noted the growth HIV-infected patients for medical aid appealability and income for urgent reasons into the hospital by 1,5 (p=0,0042) and 1,7 times (R2=0,57, p=0,03), respectively. During the analyzed period the number of patients with newly diagnosed HIV infection in hospital went up by 3.6 times (p<0.0001). Among men the augmentation was 3.3 times (R2=0,59, p=0.02) and for women this increased by 5.4 times (R2=0,47, p=0,06). It marked the growth of a share of new cases of HIV infection in the age groups 31—40 and 41—50 years. The detectability of new HIV cases in men during the observation period were higher than in women and had statistically significant differences (p<0,05). The dynamics of requests for medical aid for men and women with newly diagnosed HIV infection among different age groups was different. It has been shown a statistically significant trend towards an increase in admission to the RIEM among men (R2=0,63, p=0,018) in the age group of 31—40 years and men (R2=0,76, p=0,005), and women (R2=0,57, p=0,03) in the age group 41—50 years. At the same time, most often HIV infection identified among socially unadapted persons with marginal behavior. Patients in emergency hospital can be considered as the focus groups for studying the features of the HIV epidemic process while consumers of psychoactive drugs, patients with urgent surgical pathology, and individuals suffering from medical and social deviations are indicative groups of high risk for HIV infection spreading in health care facilities, and the city of Moscow.
