The Reduction in Antibiotic Use in Hospitals

Area of Science:

• Infectious Diseases
• Hospital Administration
• Pharmacology

Background:

• Sepsis and pneumonia affect over 350,000 patients annually in German hospitals.
• High rates of antibiotic use in hospitals contribute to the growing problem of antimicrobial resistance.
• There is a critical need to re-evaluate and optimize antibiotic treatment strategies.

Purpose of the Study:

• To evaluate the impact of a hospital-wide intervention aimed at reducing antibiotic consumption.
• To assess the effect of decreased antibiotic use on patient mortality and microbiological resistance patterns.
• To determine the feasibility and outcomes of a more focused antibiotic administration approach.

Main Methods:

• A retrospective analysis of hospital mortality and microbiological data was conducted.
• Antibiotic use was reduced through specialized training, standardized algorithms, and uniform recommendations.
• Data from 2010-2011 (high antibiotic use) were compared to 2012-2013 (reduced use).

Main Results:

• Antibiotic consumption decreased by 24% (from 67.1 to 51.0 DDD per 100 patient days).
• Mortality for sepsis patients fell from 19% to 1%, and for pneumonia patients from 12% to 6%.
• Overall hospital mortality decreased from 3.0% to 2.5%, and resistance to antibiotics in Gram-negative UTIs dropped from 11% to 5%.

Conclusions:

• Reducing in-hospital antibiotic use is an achievable objective.
• Lower antibiotic consumption was associated with decreased patient mortality and reduced antimicrobial resistance.
• The study supports a more limited and focused approach to antibiotic administration in hospitals.
