On June 24, 2003, representatives of over 80 hospitals; 15 local, State, and Federal agencies; the Medical Society of the State of New York; nursing homes; and home care providers attended a table-top exercise that was conducted by the Naval War College at GNYHA headquarters. The exercise was designed to highlight potential challenges for hospitals in preparing for and responding to possible incidents, and to identify services and support that government agencies might provide and areas that might require strengthening both within a hospital and across the region. GNYHA will be using comments from members regarding the exercise, together with the Naval War College's "After Action Report," to direct GNYHA's future emergency preparedness activities on behalf of its members.
