Objectives: Maintaining cleanrooms in a hospital is a key part of preventing healthcare-associated infections (HAIs). The aim of this work was to verify the effectiveness of anti-epidemic measures to ensure air quality in cleanrooms in a tertiary care hospital.
Methods: The study was based on the application of anti-epidemic measures and verification of their effectiveness by regular indoor air monitoring between the years 2014-2019. Monitoring was performed according to a recommended procedure based on European standards for cleanrooms.
Results: The results demonstrate a reduction in the number of airborne particles and the number of colonies, as well as the elimination of fungi and conditioned pathogens in air samples.
Conclusions: The authors emphasize the importance of established anti-epidemic measures and regular monitoring for the prevention of HAIs.
