The presence of effective trauma systems may be a major factor in keeping murder rates from rising in recent years, according to a 2003 study. The authors concluded that the homicide rate in the United States is about three times lower than it should be based on the increase in violent crimes since 1931. Unfortunately, 15 states do not have an organized trauma system.

Emergency Room Visits Up 20% 
                                                                                   

Emergency room visits increased more than 20 percent from 1992 through 2001, and only 10 percent of cases handled were classified as non-urgent. Injuries, poisonings and adverse effects of medical care accounted for one-third of ER visits. Falls were the leading injury, and persons over age 75 had the highest rate of visits - 60 per 100 patients.
