Epidemiological situation on viral hepatitis В and С among medical workers in the Voronezh region

Abstract

One of the leading problems of modern health care is nosocomial infection of health care workers with bloodborne infections viruses, including parenteral viral hepatitis B and C. The aim of the study was to assess the frequency of detection of markers of hepatitis B and C based on the results of screening studies and the incidence of viral hepatitis B and C among medical workers and the general population of the Voronezh region, to analyze the structure of emergency situations in medical organizations. A retrospective descriptive study was conducted, the materials of which were data on the frequency of occurrence of markers of parenteral hepatitis, the incidence of viral hepatitis B and C among medical workers, and the frequency of registration of emergency situations. Analysis of the incidence and results of screening examinations for markers of viral hepatitis B and C among medical workers in the Voronezh region for the period 2011–2018 revealed a pronounced trend towards a decrease in the prevalence of this pathology. However, the indicators remain at a consistently high level among the staff of the hemodialysis, hematology, and surgery departments. The annual frequency of registering emergencies for the specified period was from 1.7 to 3.1 per 1000 workers. It has been established that most often medical accidents occur among middle medical personnel and auxiliary health care workers. More than half of the respondents (53.0 %) answered in the affirmative to the question about the emergency situation in their professional activities, only a fourth (26.0 %) carried out emergency postexposure prophylaxis of viral hepatitis B. Insufficient adherence of medical workers to timely accounting of injuries, low level of knowledge of algorithms of behavior in an emergency situation, a significant underestimation of emergency situations in medical organizations require close attention.
