"Many patients who live in the community and need some degree of medical assistance may be unable to manage if their resources or services are depleted during a mass casualty event (MCE). Patients who are not directly affected by an MCE but who have daily medical needs, those who cannot manage their medical needs in a shelter, and those who do not have family caregivers are likely to seek care at hospitals that will already be burdened by caring for people directly affected by the MCE. This study investigates data sources to enumerate and estimate the number of people who, though not directly affected by an MCE, might seek hospital care during an MCE. The report summarizes findings about the availability of data to quantify the at-risk community population. The city of Worcester, Massachusetts, was selected as the test area for determining how many residents in a geographic area fall into one of the major at-risk categories. Worcester is located in central Massachusetts, 45 miles west of Boston, with a population close to 175,500. It is the second largest city in New England."
