Purpose: The purpose of this study was to determine if routine chest X-rays (CXRs) performed after chest tube (CT) removal in pediatric patients provide additional benefit for clinical management compared to observation of symptoms alone.
Methods: A single-center retrospective study was conducted of inpatients, 18 years or younger, who had a CT managed by the pediatric surgery team between July 2017 and May 2019. The study compared two groups: (1) patients who received a post-pull CXR and (2) those who did not. The primary outcome of the study was the need for intervention after CT removal.
Results: 102 patients had 116 CTs and met inclusion criteria; 79 post-pull CXRs were performed; the remaining 37 CT pulls did not have a follow-up CXR. No patients required CT replacement or surgery in the absence of symptoms. Three patients exhibited clinical symptoms that would have prompted intervention regardless of post-pull CXR results. One patient had an intervention guided by post-pull CXR results alone. Meanwhile, another patient had delayed onset of symptoms and intervention. No patients required an intervention in the group that did not have a post-pull CXR.
Conclusion: Chest X-ray after CT removal had a very low yield for changing clinical management of asymptomatic patients. Clinical symptoms predict the need for an intervention.
