Frequently asked questions on the use of mobile phones in hospitals

Can mobile phones affect some medical devices/equipment?
Yes, under certain circumstances the electromagnetic interference from a mobile phone can affect the performance of some medical devices. We have received reports where this has happened (see 'Oh yes they do' in One Liner issue 33).

Does the MHRA recommend a blanket ban on the use of mobile phones in hospitals?
No, we recognise that mobile phones are in everyday use and provide a practical means of communication for many people. However, mobile phones do transmit radio waves, which can adversely affect some medical equipment. Therefore we recommend that hospitals/trusts develop local rules to minimise the risk of interference with critical medical equipment.

Are there any specific areas in hospitals where the MHRA recommends a ban on mobile phones?
Areas of restriction are down to the individual hospital/trust but we recommend that mobile phones are not used in critical care areas such as intensive therapy units (ITU), special care baby units (SCBU) or where patients are attached to complex devices, as any effect on such equipment could be extremely detrimental to patient care.

Does the MHRA provide posters to indicate areas where mobile phones should not be used?
We have produced two posters that can be displayed to indicate areas where mobile phones can or can't be used.

Has the MHRA published any additional guidance on the use of mobile phones in hospitals?
Yes, we have further guidance on the use of mobile phones and other communication devices in: 'Mobile communications interference'.

Is the risk of interference the only reason why hospitals limit the use of mobile phones?
No, there are many reasons why hospitals may limit mobile phone use, including:

• telephone ringtones may disturb and/or alarm patients who are resting
• telephone ringing and subsequent conversations may disturb important patient/healthcare professional discussions
• the use of camera phones may compromise patient confidentiality
• alarm tones on medical equipment may be overlooked if confused with telephone ringtones.
