A lockdown at Moses Cone Hospital in Greensboro, N.C., caused confusion throughout the facility because of what the hospital called "unclear policies and protocols," according to an article on the Fox8 website. Moses Cone is now working to make sure that doesn't happen again.

The Moses Cone Hospital was put on lockdown at 7:10 p.m. on a recent Saturday and came out of lockdown about an hour later. The entrances were closed except for the ambulances. The hospital then continued to run normally but with a heightened sense of security.

The lockdown stemmed from a threatening phone call received by an employee. The employee then contacted the PBX operator, and the lockdown was initiated.

"The initial overhead announcement, however, included incorrect information including the phrase 'active shooter,'" the hospital said in the email. "This message was not corrected nor were any updates made overhead until an all-clear announcement came more than an hour later."
