For Loma Linda (Calif.) University Medical Center and its emergency department staff, waiting for a large surge of patients who were victims of the Dec. 2 mass shooting in San Bernardino, Calif., was a matter of putting their training to use.

As soon as Loma Linda UMC received a message that a mass shooting had occurred, Kathleen Clem, M.D., emergency medicine department chair, raced to find the hospital’s on-call ED physicians who, as luck would have it, were already on-site for a meeting.

Even though they were not certain of the scope of the shooting, which killed 14 and injured 21, the hospital was ready for a large number of patients. Loma Linda UMC is only 3 miles from Inland Regional Center, the site of the attack, and the only Level I Trauma Center in a five-county region.
