Study Overview
Brief Summary
The study will be conducted in 2 phases (A and B) using two different groups of patients in order to prove that an early prescription of radiography using the Ottawa Ankle Rules by a nurse practitioner could shorten length of stay of a patient suffering from ankle trauma at the Hospital Center of Saint-Brieuc.
Detailed Description
Ankle sprain is an injury very frequently encountered during consultation in hospitals emergency departments. Its mechanism may at times leads to fracture. The Ottawa Ankle Rules (OAR) provide guidelines to clinicians concerning the need to perform radiographic test to verify whether patients with ankle injuries are suffering from fracture. If all clinical and anamnestic criteria are negative in accordance with the OAR, the probability of a fracture being present is about 0% (IC 95%). OAR are validated for adults.
Actually, a meta-analysis has suggested that it may be beneficial to introduce a nurse-initiated radiographic test protocol as a standard practice in emergency departments. However this early prescription is not a standard of care in most of emergency departments in France.
The implementation of OAR decreases irradiation levels of patients and reduces medical expenses. In addition, it allows to reduce patient's duration of stay in already encumbered emergency departments, thus reducing also overcrowding, which is known to be a major factor of non quality of care in such departments.
The study will be conducted in 2 phases of 4 weeks each :
- The first one (Phase A) will occur in the emergency department with the application of OAR only by the physicians (without changing the standard of care)
- The second one (Phase B) will occur after the Phase A, and nurses will apply OAR before physicians, according to the protocol.
