Epidemiological characteristics of HIV infection in multidisciplinary hospitals of a large metropolis (Moscow)

The aim of this study was to evaluate the epidemiological characteristics of patients in multidisciplinary hospitals of a large metropolis (Moscow) and assess the representativeness of the data for estimating current trends in HIV prevalence in Moscow.
Materials and methods. At the first stage of the study, the hospitalised contingent of Moscow multidisciplinary hospitals was characterized, including their socio-demographic data, as well as their affiliation with the profile of specialised medical care. Then, after assessing the representativeness of the sample, the prevalence of HIV infection among the adult Moscow city population was estimates. Continuous variables between groups were compared using Student’s t-test. Categorical variables between groups were compared using appropriate criteria (the Fisher’s exact test with Bonferroni multiplicity correction and the Pearson’s chi-squared test). A p-value <0.05 was considered statistically significant.
Results and discussion. The prevalence of HIV infection in the hospitalised population was 0.39% (95% CI: 0.37–0.41%). The highest HIV prevalence (p<0.01) was found in the profiles: Toxicology, Psychosomatics, Purulent surgery, Therapy and Intensive care. The lowest prevalence was noted for the profiles of Oncology, Gynecology and Cardiology. Among all patients in multidisciplinary hospitals with detected HIV infection, the largest proportion was accounted for by residents of Moscow — 51.96%; among newly diagnosed HIV infected patients — by non-resident citizens (43.24%). The estimated number of adult people living with HIV (PLWH) in Moscow was 42 271.
Conclusions. Thus, 96% adult of PLWH in Moscow are aware of their HIV status, which marks the effective work of the health care system on HIV infection in Moscow.
