Using a checklist to assess if a child undergoing MRI needs general anaesthesia.

Area of Science:

• Pediatric Imaging
• Medical Assessment Tools
• Anesthesiology

Background:

• Magnetic Resonance Imaging (MRI) often requires general anesthesia (GA) for pediatric patients to ensure cooperation.
• Predicting the need for GA in children undergoing MRI is crucial for optimizing patient care and resource allocation.

Purpose of the Study:

• To evaluate the efficacy of a child-assessment checklist in determining the requirement for general anesthesia (GA) during pediatric MRI examinations.
• To assess the diagnostic accuracy and inter-rater reliability of the checklist.

Main Methods:

• A prospective study involving 798 children undergoing MRI, assessed pre-examination using a five-item behavioral checklist.
• Binary logistic regression analysis was used to identify factors associated with GA requirement.
• The checklist's performance was evaluated using the area under the curve (AUC).

Main Results:

• Children requiring GA were significantly younger and scored higher on the checklist in both the overall sample and a subset of younger children (p<0.001).
• The checklist demonstrated good diagnostic accuracy (AUC=0.97) with a suggested cut-off score of 4.
• High inter-rater reliability (Intraclass Correlation Coefficient = 0.78) was observed.

Conclusions:

• The child assessment checklist is a valuable tool for identifying children who require general anesthesia for MRI.
• The checklist can be reliably administered by non-medical personnel, facilitating its practical application.
