Computed tomography (CT) scans are crucial before balloon sinus dilation (BSD) surgery. While many surgeons adhere to guidelines, a significant number do not obtain necessary CT imaging, indicating a need for better practice monitoring.
Area of Science:
- Otolaryngology
- Medical Imaging
- Health Policy
Background:
- Computed tomography (CT) imaging is a standard prerequisite for sinus surgery, including balloon sinus dilation (BSD).
- Adherence to practice guidelines ensures optimal patient care and surgical outcomes.
- Variations in adherence can impact the quality of care and necessitate further investigation.
Purpose of the Study:
- To evaluate the adherence of otolaryngologists to practice guidelines regarding the use of CT imaging prior to balloon sinus dilation (BSD) procedures.
- To identify the prevalence of non-adherence and explore potential factors associated with it.
Main Methods:
- A cross-sectional study utilizing Medicare claims data from January 1, 2022, to December 31, 2023.
- Identified otolaryngologists performing at least 11 BSD procedures annually.
- Analyzed the availability of preprocedure CT imaging within one year of BSD and identified outlier physicians.
Main Results:
- The study analyzed 19,692 BSD procedures performed by 490 otolaryngologists.
- Preprocedure CT imaging was unavailable within one year for 15% of patients (2905/19692).
- 31.8% of otolaryngologists (156/490) were identified as outliers, with a subset accounting for a disproportionate number of cases lacking CT imaging.
Conclusions:
- Most otolaryngologists adhere to guidelines by obtaining pre-BSD CT imaging.
- A substantial minority of physicians do not consistently obtain necessary CT imaging, failing to meet standard practice guidelines.
- Improved monitoring systems are needed to ensure consistent adherence to CT imaging standards before BSD.
