Medical Surge Capacity Metrics
Medical surge capacity has been an important concern for
contingency planners. Homeland Security Presidential Directive
(HSPD)-21 directly raises this concern. The purpose of this study
is to translate the most up to date science on surge capacity into
a functional tool - in this case an applet that allows its user to
estimate surge capacity for a given hazard in a given medical
facility. Since the end-user has control over the input variables,
the effect of certain operational tactics and strategies on
augmentation or degradation of surge capacity can be ascertained.
This control also provides the end product with adaptability that
could inform various other sectors. This allows a facility to plan
a phased implementation of surge response as dictated by the
size of the surge.
Completed Project Overview
The focus of the Surge Capacity Metrics project was to ensure
that individuals tasked with preparing their facility for an
unexpected, catastrophic event are better prepared to handle the
large influx of patients.
The outcome of the fundamental research behind this project is
an innovative application, entitled Surge. The application is an
easy-to-use new tool targeted towards hospital administrators and
emergency planners to assist in assessing readiness for a
suddensurge in patients from an unplanned, large-scale event.
Surge can simulate bed expansion, inflow and outflow
alterations, andinterventions to increase capacity or make room for
disaster patients.In the first phase (year one), investigators
reviewed literature regarding hospital surge and interviewed
hospital personnel to identifyand fully describe all variables that
may have an impact on hospital surge.
The applet has been written in JAVA and C# in order to facilitate
ease of use and accessibility. The applet was developed with input
from investigators and interviews withknowledgeable hospital
personnel and with the end-user in mind. The draft user interface
was sent to a group of hospital planners fo revaluation and
finalized based on their feedback.
