Hypothesis
The study evaluates the effectiveness of a new 2-view abdominal radiograph exam protocol for G-tube malposition in children.
Conclusion
The new diagnostic exam performed well with high test yield, accuracy, specificity, and negative predictive value.
Supporting Evidence
- 227 exams were performed in 186 patients.
- The 2-view radiograph protocol was followed in 81.9% of cases.
- 79.7% of exams had a reporting time under 1 hour.
- Indeterminate exams added a median time delay of 40 minutes.
- Test performance showed a yield of 94.3% and accuracy of 97.3%.
Takeaway
Doctors tested a new way to check if feeding tubes are in the right place using X-rays instead of older methods, and it worked really well.
Methodology
Retrospective chart review of G-tube radiographic exams performed at two hospitals.
Limitations
The study is limited to a retrospective review and may not capture all variables affecting exam outcomes.
