Parents prefer ultrasound (US) over CT scans for diagnosing appendicitis in children, prioritizing low cancer risk and accuracy. They favor MRI over US when accuracy is high, despite concerns about noise and claustrophobia.
Area of Science:
- Pediatric Radiology
- Medical Decision Making
- Diagnostic Imaging
Background:
- Appendicitis is a common surgical emergency in children.
- Diagnostic imaging is crucial for accurate appendicitis diagnosis.
- Parental preferences can influence the choice of diagnostic imaging tests.
Purpose of the Study:
- To determine parental preferences for diagnostic imaging tests (DITs) for pediatric appendicitis.
- To rank attributes influencing DIT selection.
- To identify DIT attributes that would prompt parents to switch their choice.
Main Methods:
- Parents of children with suspected appendicitis were interviewed.
- Paired comparisons of DITs (US, CT, MRI) were conducted.
- Attribute importance and preference-switching points were assessed.
Main Results:
- Parents preferred US over CT (68%), prioritizing lower cancer risk and accuracy.
- Parents preferred MRI over US (78%), valuing accuracy and shorter scan times.
- Key factors influencing preferences included cancer risk, accuracy, pain, scan length, sedation, and claustrophobia.
Conclusions:
- Ultrasound and MRI are preferred DITs for pediatric appendicitis investigation.
- Parental preferences are influenced by a balance of safety, accuracy, and test experience.
- Understanding these preferences can aid in shared decision-making for pediatric appendicitis imaging.
