Epidemiological surveillance of the tuberculosis patients’ death cases in the city of Moscow

Abstract

The article describes the methodology for monitoring the mortality of patients with tuberculosis in the city of Moscow, which includes the collection of data from several sources to clarify information on deaths, the determination of the lifetime status of patients’ registration as a TB patients and the status of their residence in the city.
The monitoring system examines deaths in terms of identifying a «TB death as a TB infection nidus» in the city for appropriate antiepidemic measures. This determines specific approaches to the processing and analysis of data that include all deaths occurring in the city area during the reporting period, regardless of the Russian regions in which they were registered and at what time interval the death was registered. The monitoring system made it possible to assess not only the very fact of a significant decrease in the mortality rate observed in recent years in the city, but also to study its components, which will allow us to determine the possibilities and ways of influencing its on the indicator level in the future.
It is shown that the TB mortality rate in the city has a fivefold decrease from 2001 to 2016 – from 12.4 to 2.5 per 100K. Only in 2012–2016 there was a 25% decrease in the TB mortality rate. In 2016 the proportion of permanent residents among those who died from tuberculosis became less than 50%, reaching 47.2%. 66.5% of died TB patients were not associated with tuberculosis and included, primarily, those who died of HIV infection – 49.1% of all deaths.
