Brief Summary
The frequency of head computed tomography (CT) imaging for mild head trauma patients has raised safety and cost concerns. Validated clinical decision rules exist in the published literature and on-line sources to guide medical image ordering but are often not used by emergency department (ED) clinicians. Using simulation, we explored whether the presentation of a clinical decision rule (i.e. Canadian CT Head Rule - CCHR), findings from malpractice cases related to clinicians not ordering CT imaging in mild head trauma cases, and estimated patient out-of-pocket cost might influence clinician brain CT ordering. Understanding what type and how information may influence clinical decision making in the ordering advanced medical imaging is important in shaping the optimal design and implementation of related clinical decision support systems.

Outcome Measures
Primary Outcomes (1)
brain CT medical image order
At each decision point clinician asked to decide on which image to order for patient among three choices: * CT Head without/with contrast * CT Head without contrast * No medical imaging
30 days
Study Arms (2)
LEGAL-COST
EXPERIMENTALClinicians were first presented malpractice case law summary information (which suggests clinician not likely to be sued for not ordering CT scan) then patient out-of-pocket cost information for brain CT image (which provides them insight into what the patient is likely to pay for the test)
COST-LEGAL
ACTIVE COMPARATORClinicians were first presented with patient out-of-pocket cost information for brain CT image (which provides them insight into what the patient is likely to pay for the test) then malpractice case law summary information (which suggests clinician not likely to be sued for not ordering CT scan)
Interventions
Clinicians asked to make decision on medical imaging for their simulated patient after presentation of clinical case then additional information. At each presentation of new information the clinician may modify their image order.
