This educational session will present data on environmental and self-contact patterns among healthcare personnel (HCP) and characteristics of toilet aerosol generation during patient care. Healthcare activities were observed among 52 patients, totaling 164 observations of environmental contact and self-contact patterns of HCP. The surface contacted by HCP during the majority of visits was the patient. Environmental surfaces contacted by HCP included: tray tables, bed surfaces, bed rails, computer stations, and IV poles. Regression models showed that physical exam and respiratory treatment were associated with increased number of patient contacts and self-contact of HCP. Toilet aerosols were characterized using an optical particle counter (OPC) and a toilet typical for use in a patient care setting was repeatedly flushed. Aerosol measurements were recorded based on particle size and sampling location.Median concentration of particle counts were the highest among particle sizes 0.5µm and 1µm at 0.15 m above the toilet near the toilet handle. These data provide guidance for sampling strategies for studies performing microbial risk assessment and for the implementation of control strategies to reduce health care acquired infections.
