There has been a dramatic increase in the number of mass shootings (loosely defined as an incident with four or more indiscriminate victims) in the United States (1). Additionally, the use of high-caliber, military-style weapons, has become more common in civilian shootings. These trends should influence how emergency departments prepare for disasters, including an inventory of what critical care medical materials (supplies) are readily available in the event of a disaster.

To demonstrate the need for the adoption of medical materials planning for disasters to account for new injury patterns from mass shootings.

A review of injury patterns from recent mass shootings was conducted using available literature (2). The average number of victims presenting to the emergency department in these events was reviewed. Estimation of critical care specific medical materials in the emergency department required for the management of an “average” number of victims with the typical injury pattern of these events was conducted.

Some critical care specific medical materials: intubation equipment, chest tubes, and central venous catheters may be in short supply during a mass shooting event.

Emergency physicians must anticipate and prepare for new disaster trends such as mass shootings and high caliber weapons injuries. This includes having specialty medical supplies readily available in sufficient amount. Normal stocking of critical care specific medical materials may be inadequate in a mass shooting event based on the available literature.
