Abstract

Objective: To determine whether microbial contamination of door handles in two busy intensive care units and one high dependency unit was related to their design, location, and usage. Design: Observational study of the number of viable bacteria on existing door handles of different design at defined entry/exit points with simultaneous data collection of who used these doors and how often. Setting: Two busy specialised intensive care units and one high dependency unit in a tertiary referral NHS neurological hospital. Main outcome measures: Surface bacterial density on door handles with reference to design, location, and intensity of use. Results: We found a significant correlation between the frequency of movements through a door and the degree to which it was contaminated (p =
