Re: Dial M for MRSA

Whilst recently on a pediatric cardiac intensive care unit for
several days, I
was struck by how senior consultant mobile phone did not cause any
inference even when used in close proximity to children, whereas,
by the Herculean efforts of nursing staff to police their use, those of
people would have. I could find no explanation of this differential effect
in the

Richard Brady points out that the ‘basic requirements expected in
editorial on mobile phone usage in hospitals is that ‘an accurate and up
date review of the new research be regarded and evaluated’. He then cites
case report by Hahn et al of a child’s death attributed to mobile phone
but as far as I can see from my reading of the article, the child did not
but suffered ‘pulmonary edema, ECG changes, and myocardial damage as
evidenced by elevated cardiac enzymes’. No indication is given of the
of these effects.

Regarding bacterial contamination, no doubt mobile phones do get
contaminated with bacteria that may cause nosocomial infections, but then
mobile phones do so do other phones, pagers, computer
keyboards (1) and all other surfaces which are frequently handled . In
because mobile phones tend to be used mainly by their owners the risk of
transmission is probably lower compared to landlines and computer
keyboards which are shared. In any case, the solution to this is correct
disinfection and not a ban on phones, pagers or computers.
