Nurses or physician assistants designated as patient navigators can ease the burden on the rest of the staff, improve relations with outside physicians, and improve patient flow in your ED. Provide them with separate phone numbers that primary care physicians can call to check on the condition of referred patients. Make them an integral part of your bed flow team, and have them serve as liaisons to admitting. Navigators also can be used to check with radiology when test results appear to be delayed.
