Faced with a limited budget and pressure to improve efficiency, you have conducted an audit of radiologic procedures ordered for minor trauma and have found that the rate of radiographs ordered for ankle and knee trauma is high. You are aware of the Ottawa Ankle Rules, which help identify patients for whom it is safe to omit ankle radiographs without adverse consequences (Figure 19.4-1).1,2 You are aware that only a small number of your institution's faculty and residents currently use the Ottawa Ankle Rules in the emergency department.You are interested in knowing the accuracy of the Ottawa Ankle Rules, whether they are applicable to the population of patients in your hospital, and whether you should implement them in your own practice. Furthermore, you wonder whether implementing these rules can change clinical behavior and reduce costs without compromising quality of care. You decide to consult the original medical literature and assess the evidence for yourself.
