Table 2 Current and future solutions to key disadvantages of walkie talkie use in health care settings
Issue | Current solution | Future solutions |
|---|---|---|
Non-secure channel | - Avoid patient identifiable information - Frequency hopping: a coordinated channel switch by the team arranged off an open channel | - Investment into secure radio systems that use: Encrypted frequencies Automatic frequency-hopping |
Miscommunication between multiple teams sharing the same channel | - If more than one different department using walkie talkies, department heads should establish which channel to use for each team to keep communications separate. | |
Radio frequencies may be obstructed by hospital structures (e.g. lead lining within radiotherapy departments) | - To be aware of signal loss zones and make sure alternative means of communication are available | - Increased transmission power of radio (requires listened frequencies) - Use of radio repeater |
Specific communication approach required | - Communication should be clear, structured and succinct. It must be obvious who you are and who you are trying to contact. For example: “Person A: This is Person A calling Person B, come in Person B, over ….” “Person B: This is Person B receiving over … ..” | - Teaching on use of walkie talkie communication and etiquette as part of departmental staff induction - Simulation training to incorporate walkie talkies |
