MedCon:Pre-Event - A Tool to Estimate the Pre-Event Population at Risk of Medical Consequences in a Disaster [open html - 467KB]
"The MedCon:Pre-Event has been designed to estimate the baseline medical care requirements (i.e., the number of persons that would require medical care) of a displaced population following a disaster due to pre-existing medical conditions. Users of MedCon:PreEvent should note that the MedCon:Pre-Event has not been designed for estimating the medical care requirements due to direct impact of the event (e.g., injuries and illness) or additional medical care requirements resulting from the aggravation of the existing medical condition. The intended users of the MedCon:Pre-Event model are public health preparedness planners at local, state, and federal levels involved in addressing the large scale medical care requirements resulting from man-made and natural disasters." Microsoft Excel-based tool and manual available for free download.
