Summary

This audit assessed vestibular schwannoma screening, finding good guideline adherence and appropriate use of MRI scans. Screening activity increased initially but stabilized, with fewer inappropriate requests after guideline reminders.

Area of Science:

  • Otolaryngology
  • Neurology
  • Radiology

Background:

  • Vestibular schwannomas require timely diagnosis.
  • Screening MRI (magnetic resonance imaging) is crucial for detecting these tumors.
  • Auditing screening practices ensures guideline adherence and efficient resource allocation.

Purpose of the Study:

  • To audit the practice of vestibular schwannoma screening in a sub-regional ENT (ear, nose, and throat) center.
  • To assess the agreement between established guidelines and the actual indications for screening MRI.
  • To evaluate the impact of guideline reminders on scan request appropriateness.

Main Methods:

  • An audit loop was completed to assess screening practices.
  • Data on patient selection for screening MRI were collected and analyzed.

  • The proportion of diagnosed cerebellopontine angle tumors and reasons for screening were compared to guidelines.

    • Main Results:

    • Good agreement was observed between given guidelines and indications for screening MRI.
    • The proportion of diagnosed cerebellopontine angle tumors aligns with UK reports.
    • Screening activity increased post-guideline introduction but plateaued; inappropriate requests decreased after guideline reminders.
    • An increase in screening for unilateral tinnitus was noted but remained within reasonable estimates.

    Conclusions:

    • The implemented vestibular schwannoma screening guidelines are effective and well-adhered to.
    • Guideline reminders successfully reduced inappropriate MRI scan requests.
    • The screening program demonstrates a stable and appropriate level of activity post-implementation.
