The descriptive retrospective epidemiological study of Acinetobacter spp. cases in healthcare units was performed in Kemerovo regions (2012–2016). Total 113967 outcomes of treatment were studied and 1742 Acinetobacter spp. were identified. The incidence of Acinetobacter spp. was 15.29 per 1000 patients, the share of this pathogens was 1.32%. Frequency of Acinetobacter spp. cases in adults was 2.15 times higher than in children, χ2 = 105.609, p = 0.000. We revealed a trend to decrease the incidence of Acinetobacter spp. (the average growth rate is 53.7%, the average growth rate is 46.3%, y = -2.054x + 21.346, R² = 0.8692) during the long-term period (2012–2016). Acinetobacter spp. prevalence differed in 28.5 times from 2.55 to 72.16 per 1,000 patients, p = 0,000. Patients of neurosurgical units were under the highest infection risk. The Acinetobacter spp. incidence in the intensive care units was 34.84 per 1000 patients. Among all the isolated Acinetobacter spp. 46% of the strains were resistant to carbapenems (7.12 per 1000 patients), while for the units with a high risk of infection it reached to 19.0 per1000 patients (p = 0,000).
