Assaults against emergency department staff at New Zealand's Middlemore Hospital have increased, forcing nurses to wear personal alarms, according to an Article on the NewsHub website.
The staff are also being trained in de-escalation techniques.
The security measures come after a report on violence in the hospital's emergency department revealed that the number of calls to security had increased from 31 in December 2016, to 65 at the same time in 2017, the article said.
The alarms come attached to a keychain with a pin that can be pulled to activate an alarm.
