Hospital door handle design and their contamination with bacteria: a real life observational study. Are we pulling against closed doors?

<h4>Objective</h4>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.<h4>Design</h4>Observational study of the number of viable bacteria on existing door h...
