Ankle injuries are a very common injury in children. Each year approximately 35000 kids
present to Ontario emergency departments (ED) with this problem. Right now, about 90% of
these children get x-rays of the injured ankle, even though only 12% of these x-rays show a
break in the bone. Some excellent research has created some rules that doctors can use to
help them decide which children really need x-rays. Unfortunately, even though these rules
have been proven to safely reduce x-rays by as much as two-thirds, most doctors are not using
these rules.
Therefore, this study will be the first to put the best paediatric ankle x-ray rule, the Low
Rick Ankle Rule, into physician practice in EDs. Our main goal is to determine how much we
can reduce ankle x-ray rates in EDs that use this rule regularly versus those that do not. If
we show that doctors can safely use this rule regularly and the number of ankle x-rays will
be significantly less, this will lessen unnecessary potentially harmful radiation exposure in
children, these children will spend less time in an ED, and the health care system will save
money.

Inclusion Criteria: - All otherwise healthy children between the ages of 3 and 16 years of age that present to the participating EDs with an isolated acute (< 72 hours) blunt ankle injury due to any mechanism of injury will be eligible for the study. The age criteria were chosen to match those ages in which the LRAR was validated. Exclusion Criteria: 1. Children with ankle injuries who were referred from outside the hospital with radiographs. 2. Children with ankle injuries who returned for reassessment of the same ankle injury. 3. Children with open wounds on their ankle and/or foot 4. All children at risk for pathological fractures such as those with congenital or acquired generalized bony disease (Appendix I). Clinical presentation and risks in these cases may be altered. 5. Congenital anomalies of the feet and/or ankles (eg club feet, tarsal coalition). These abnormalities may have features which may complicate clinical assessment. 6. Patients with known coagulopathies. Underlying hemarthrosis may complicate clinical assessment. 7. Patients with cognitive and/or developmental delay. These patients may not localize pain. 8. Injuries greater than 72 hours old. The signs and symptoms of the most common fracture, the Salter-Harris I fracture of the distal fibula, may be diminished. Our ability to make this clinical diagnosis with confidence may thus be compromised. 9. Recent history of surgery or closed reduction of the same ankle within the last 3 months. These prior events may confuse current presenting symptomatology and ability to weight-bear and recover normally. 10. Patients with low risk injuries who do not have phone or electronic mail access and/or have an insurmountable language barrier. This will preclude follow up. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | To assess the impact of a LRAR implementation strategy on paediatric ankle radiography rates in participating EDS. | three six month phases of implementation | ||
Secondary | Ankle x-ray rate changes at individual hospital from pre-LRAR to post-LRAR implementation phases. | duration of subjects participation in study | ||
Secondary | Intervention and control sites will be compared individually and collectively, during the post-LRAR for: missed significant fractures, number of unscheduled x-rays following initial ED visit, total length of stay, patient and physician satisfaction | duration of subjects participation in study | ||
Secondary | To determine the sustainability of the clinical impact of the LRAR strategy at intervention sites by comparing high and low intensity implementation phases with respect to weekly x-ray rates, missed fractures and physician and patient satisfaction | duration of subjects participation in study | ||
Secondary | To evaluate the performance of the LRAR during the implementation period of the rule at intervention sites with respect to: sensitivity and specificity of the LRAR for detecting "high risk" fractures and physician compliance with use of the rule | duration of subjects participation in study | ||
Secondary | To compare total costs of "low risk injuries" at intervention versus control sites during the post-LRAR implementation phase. | duration of subjects participation in study |
