Why the alphabet soup in discharge summaries is a menace

Dr Anna Coghlan recently exposed the alphabet soup frequently served up in hospital discharge summaries written for GPs.
As a junior doctor and now a GP registrar in Brisbane, she was the lead researcher on a recent study showing that a local hospital’s typical discharge letter had some 13 different abbreviations on average.
The figure was identified after she and two colleagues trawled through 800 discharge summaries issued over a single week, with one example containing 86 short forms.
