U.S. emergency rooms are failing to identify elder abuse, a new study suggests.

The issue: Elder abuse is a serious problem worldwide. In the United States, an estimated 1 out of 10 people ages 60 and older who live at home experience elder abuse, according to the U.S. Centers for Disease Control and Prevention (CDC). Many senior citizens, however, never report the fact that they have been physically or sexually abused, neglected, exploited or otherwise mistreated.

As America’s elderly population continues to grow, a host of state and federal laws aim to prevent abuse, including the Older Americans Act Reauthorization Act of 2016. The new law expands on the original Older Americans Act of 1965, partly by strengthening elder abuse screening and prevention efforts.
