The AHRQ Hospital Surge Model estimates the resources needed in your hospital(s) to treat casualties resulting from specific biological, chemical, nuclear, radiological, foodborne, or conventional explosive scenarios. For the selected scenario, the model estimates the number of casualties and the required hospital resources to treat the casualties.
This User Manual guides the user through the steps involved in running the Hospital Surge Model to select an available scenario, specify the number and/or type of casualties, and examine the output.
Step 1: Select a Scenario
Step 2: Specify Number and/or Type of Casualties
Step 3: Examine the Output
The AHRQ Hospital Surge Model estimates the resources needed in your hospital(s) to treat casualties resulting from the following scenarios:
- Biological (anthrax, smallpox, or pandemic flu, pneumonic plague).
- Chemical (chlorine, sulfur mustard, or sarin).
- Nuclear (1 KT or 10 KT explosion).
- Radiological (dispersion device or point source).
- Foodborne (botulinum neurotoxin).
- Conventional explosive (improvised explosive device).
When you run the Hospital Surge Model, you select one of the above scenarios and specify the number of casualties that your hospital(s) will have to treat. In the model, these patients are treated, as necessary, in the emergency department (ED), in the intensive care unit (ICU), or on a general medical/surgical bed ward ("the floor"). Eventually, casualties in the model are either discharged or die in your hospital(s). The Hospital Surge Model estimates the amount of resources (e.g., personnel, equipment, supplies) the casualties require while they are in your hospital(s). The model assumes that medical care is not degraded by the surge in patients or by resource constraints.
What the Hospital Surge Model Estimates
For the selected scenario, the Hospital Surge Model estimates:
- The number of casualties in your hospital(s) by hospital unit (ED, ICU, or floor) and day.
- The cumulative number of dead or discharged casualties by day.
- The required hospital resources (personnel, equipment, and supplies) to treat casualties by resource, hospital unit, and day.
How to Run the Hospital Surge Model
The Hospital Surge Model is available at http://www.ahrq.gov/prep/hospsurgemodel/. Running the Hospital Surge Model involves three steps:
