Data collection tools Site visit The site visit tool Inhibitors,research,lifescience,medical will be designed to focus on environmental factors relating to clinical care, and structural processes (such as policies and procedures, training and staff allocation). The survey strategy will assess physical

layout, equipment, staffing levels and policies and procedures pertinent to the ED management of geriatric patients.
