Poster Presentations

New this year – Posters will be available for review throughout the day in the conference center lobby. During the lunch break, presenters will be on hand to share and discuss their projects.

Stanford Emergency Response Teams

An increasing number of ambulatory clinic and business occupancy sites are located beyond the campus footprint and farther away from emergency response support. Emergency management programs developed for the hospitals do not address the unique complexities of these types of operations and locations. How will the health system protect the safety of patients, visitors, and staff; mitigate harmful impacts; and support business continuity? By developing Emergency Response Teams of specially trained personnel to activate site response procedures.

UV-C disinfection has been shown to be germicidal and the technology is employed in a variety of capacities to reduce environmental contamination loads and pathogen transmission. As part of the Management of Change process at Stanford Health Care and Stanford Children’s Hospital, Stanford Health Care EH&S performed an internal exposure/risk assessment of a unique technology that utilizes safe low-intensity UV-C through an automated process for continuous disinfection of environmental surfaces (UV Angel Desktop Model G-UVA-D01-000). The energy field entrance and motion sensor boundaries, motion sensor deactivation time and µW/cm2 of energy at various distances from the bulb were measured. A consumer exposure scenario was developed and evaluated using these measurements along with conservative consumer exposure assumptions. The NSF International assessment found that the estimated cumulative daily UV-C exposure from the automated device was below the permissible exposure limit, meeting the Cal/OSHA Standards when installed per manufacturer’s guidelines.
