- ACRONYMAWR in children
- hypothesisPatients with a wrist trauma represent a substantial part of the patient population at the Emergency Department. Most hospitals routinely carry out a radiological examination of patients following wrist trauma to exclude a distal radius/ulna fracture. However, a large part of x-rays in these patients (50%) do not show a fracture. Consequently, this means a waste of resources, an increase in patient waiting time and unnecessary radiation exposure. The applicants have developed a clinical decision rule to indicate the need for radiological examination for wrist injuries in children, called the Amsterdam Wrist Rules (AWR). The objective of this study is to evaluate the decrease in requested radiographs in case of a wrist injury with a suspicion of a distal radius fracture. In addition a cost-effectiveness analysis will be performed of direct and indirect medical costs.

- Brief summaryRationale:
Acute trauma of the wrist is one of the most frequent motives for children visiting the Emergency Department (ED). Generally, these patients are routinely referred for radiological examination. Most X-rays however, do not reveal any fractures. A clinical decision rule concerning the X-ray referral policy may help to select and percolate patients with fractures.

Objective:
To formulate a clinical decision rule to predict the presence of a distal radius/ulna fracture in children after wrist trauma, presenting to the Emergency Department and to validate this rule in a new population.

Study design:
Cross sectional, observational diagnostic study.

Study population:
All consecutive children (age 3-16 year) presenting at the Emergency Department in the participating hospitals with acute wrist trauma.

Main study parameters/endpoints:
Outcome: Distal radius/ulna fracture.
Parameters: Multiple clinical variables which can be assessed on physical examination. These parameters will be described in detail in the methods section.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness:
Any burden or risk for the participating patients additional to standard patient care in not applicable. Clinical examination and X-rays are performed as usual.
