Changing dynamics of bloodstream infections due to methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium in Germany, 2017-2023: a continued burden of disease approach.
Background: Antimicrobial resistance is a global threat to public health, with methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecium (VREfm) being major contributors. Despite their clinical impact, comprehensive assessments of changes of the burden of bloodstream infections in terms of Disability-Adjusted Life Years (DALYs) and attributable deaths over time are lacking, particularly in Germany.
Methods: We used data from the Antimicrobial Resistance Surveillance system, which covered about 30% of German hospitals. Bloodstream infections were defined by a VREfm or MRSA-positive blood culture. We estimated incidences as a first step to further use these rates to calculate DALYs and attributable deaths using the Burden of Communicable Disease in Europe toolkit. The analysis included stratification by age, sex and region.
Results: From 2017 to 2023, 6262 MRSA and 5442 VREfm blood culture-positive isolates were identified. The incidence of MRSA bloodstream infections decreased from 4.0 to 2.1 per 100,000 population, with estimated DALYs decreasing from 14.6 to 8.6 per 100,000 and attributable deaths from 591 to 316. Conversely, VREfm-BSI incidence doubled from 1.7 to a peak of 3.0 (2021) before declining back to 1.7 per 100,000 in 2023, with estimated DALYs increasing from 8.9 to 16.5 and then decreasing to 8.5 per 100,000 and attributable deaths increasing from 317 to 327. Men and people over 60 years had the highest burden, with noticeable regional differences.
Conclusion: MRSA and VREfm bloodstream infections followed different trends in the past and now present a comparable burden in Germany. Both pathogens pose a significant threat, particularly to hospitalised older aged men. Our findings highlight the need for targeted prevention and continued surveillance of MRSA and VREfm to reduce infections and their impact.
期刊介绍：
Antimicrobial Resistance and Infection Control is a global forum for all those working on the prevention, diagnostic and treatment of health-care associated infections and antimicrobial resistance development in all health-care settings. The journal covers a broad spectrum of preeminent practices and best available data to the top interventional and translational research, and innovative developments in the field of infection control.
