Redundant communication refers to having multiple back-up communication modalities and is imperative in emergency preparedness planning. Past experience demonstrates that hospitals cannot depend on just one or two means for communication. Examples include (but are not limited to):
  • Basic telephone systems
  • In-building wireless phone systems
  • Overhead announcement and paging systems
  • Nurse call system
  • Voice over Internet Protocol systems
  • Cell phones
  • Beepers and pocket pagers
  • Enterprise systems
  • BlackBerries and similar devices
  • Text messaging
  • Text-to-voice translation
  • Communication systems for the deaf and hearing impaired
  • Telephonic translation lines and services
  • Access control systems
  • Fax machines
  • Hospital television network systems
  • E-mail
  • Mass notification systems
  • Hospital electronic bulletin boards
  • Intranet message posting
  • Bed-tracking and facility status reporting systems
  • Electronic health record systems
  • Enterprise systems for networked hospitals
  • Resource and grant-asset tracking systems
  • Evacuee and disaster patient tracking systems
  • Emergency medical services communication systems
  • Emergency desktop and mobile handheld programmed radios
  • Communication with emergency operations centers
  • Public health monitoring and notification systems (syndromic surveillance systems, threat notification systems, outbreak management systems)
  • Satellite radio and communication systems
  • Ham radio systems
  • Human runners, paper and pen
