Hospital shootings are relatively rare events, according to a study published Sept. 18 by the Annals of Emergency Medicine (PDF).
The study, conducted by Johns Hopkins-affiliated researchers, found that a person is more likely to be killed by lightning than shot in a hospital or in its parking lot. Researchers studied newspaper articles and news releases published from Jan. 1, 2000, through Dec. 31, 2011, to arrive at its hospital-related results.
The research indicates that 3% of acute-care hospitals in the U.S. experienced at least one shooting event in the 12 years studied, producing a rate of 0.2% a year, findings that are consistent with Labor Department data, researchers wrote.
Among the hospital shootings that do occur, 59% occurred inside the hospital and 41% on hospital grounds, with 29% of the total taking place in the emergency department. Twenty-three percent of the shootings in the ED involved a security officer's gun taken by the shooter.
