Abstract

Problem Despite widespread acceptance of the Ottawa ankle rules for assessment of acute ankle injuries, their application varies considerably.

Design Before and after study.

Background and setting Emergency departments of a tertiary teaching hospital and a community hospital in Australia.

Key measures for improvement Documentation of the Ottawa ankle rules, proportion of patients referred for radiography, proportion of radiographs showing a fracture.

Strategies for change Education, a problem specific radiography request form, reminders, audit and feedback, and using radiographers as “gatekeepers.”

Effects of change Documentation of the Ottawa ankle rules improved from 57.5% to 94.7% at the tertiary hospital, and 51.6% to 80.8% at the community hospital (P<0.001 for both). The proportion of patients undergoing radiography fell from 95.8% to 87.2% at the tertiary hospital, and from 91.4% to 78.9% at the community hospital (P<0.001 for both). The proportion of radiographs showing a fracture increased from 20.4% to 27.1% at the tertiary hospital (P=0.069), and 15.2% to 27.2% (P=0.002) at the community hospital. The missed fracture rate increased from 0% to 2.9% at the tertiary hospital and from 0% to 1.6% at the community hospital compared with baseline (P=0.783 and P=0.747).

Lessons learnt Assessment of case note documentation has limitations. Clinician groups seem to differ in their capacity and willingness to change their practice. A multifaceted change strategy including a problem specific radiography request form can improve the selection of patients for radiography.

She acknowledges the important contribution of her mentors, Virginia Deegan and Judith Dwyer. We also acknowledge our “change champions,” without whose support this study would not have been possible. These include (but are not limited to) Dianne King, director, emergency department, Flinders Medical Centre; Sue Farr, acting manager emergency department, Noarlunga Health Services; and staff in both emergency departments, who we hope are now our new change champions. We also acknowledge the department of medical imaging at the Royal Adelaide Hospital, and Dr Jones and Partners Medical Imaging, Noarlunga Health Services. Special thanks to Rebecca McMahon for research assistance.
