Overview

Surveillance identifies surface contamination in emergency departments, indicating stress from construction and overcrowding.

Key Points

  • The aim is to understand how environmental and organizational stressors affect surface contamination in emergency departments.
  • Conducted monthly microbiological surface surveillance for 11 months.
  • Used contact plates to sample high-touch surfaces and walls.
  • Documented ED occupancy and construction activities alongside sampling.
  • Bacillus spp. contamination increased during construction phases.
  • Elevated Staphylococcus aureus levels were linked to high occupancy rates.
  • No indicator organisms were found during periods of low activity and no construction.
