Messages like “Dr. Smith, report to the OR, STAT” on public address systems could become a thing of the past in hospitals. Studies show that outdated communication systems – like PAs, pagers and other mobile devices – are confusing, inefficient and a drain on budgets. Instead, hospital staff would just communicate using their smartphones. Hospital staff could use their phones to manage schedules, send texts, and organize tasks. The devices can also be easily integrated into hospital-specific networks.
