OBJECTIVE
To assess whether a simple strategy would sustain a reduction in the number of unnecessary x ray examinations.
DESIGN
Use of posters to display guidelines encouraging the more effective use of radiology in patients with head injuries, twisted ankles, neck injuries, and abdominal pain.
SETTING
Accident department of a large metropolitan district general hospital.
PATIENTS
15,875 patients attending the accident department over two years.
MAIN OUTCOME MEASURE
Proportion of patients having radiography.
RESULTS
Referrals for skull radiography fell from 56% to 20% and those for abdominal radiography fell from 31% to 7%. Referral patterns for adults attending with twisted ankles and cervical spine injuries did not change. Reductions were sustained over two years.
CONCLUSION
Carefully designed posters provide a simple method of reducing unnecessary x ray examinations.
