Key Information Can Influence Clinician Ordering of Brain CTs
2018年2月22日 更新者:Clemson University
Effect of Clinical Decision Rules, Patient Cost and Malpractice Information on Clinician Brain CT Image Ordering: a Randomized Controlled Trial
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.
研究概览
详细说明
Multi-center, double-blinded simulation-based randomized controlled trial.
Following standardized clinical vignette presentation, clinicians made an initial imaging decision for the patient.
This was followed by additional information on decision support rules, malpractice outcome review, and patient cost; each with opportunity to modify their initial order.
The malpractice and cost information differed by assigned group to test the any temporal relationship.
The simulation closed with a second vignette and an imaging decision.

实验性的:LEGAL-COST
Clinicians 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)
|
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.
