External Review of CT Scans and Mammograms Complete

Trillium Health Partners Releases Findings and Thanks Patients, their Families
and the Community for their Understanding

Mississauga/West Toronto (December 5, 2013) – Trillium Health Partners announced today the completion of the external expert review of CT scans and mammograms, which was launched after the hospital identified a performance issue with a radiologist who previously worked at Mississauga Hospital and Queensway Health Centre.
On December 4, the hospital received a letter from Dr. Brian Yemen, the external expert hired to oversee the review, outlining his findings and conclusions. The external review found that after a rigorous assessment of 3,537 scans that included a physician-facilitated medical chart review, necessary patient retesting and medical follow-up:

  • 11 patients (0.3%) were identified as experiencing a clinically significant event:
  • 8 patients had already been picked up by the health system through other testing and clinical evaluation.
  • 3 patients were identified through the external review. They now have a diagnosis and are receiving care.
  • In more than 99% of all scans, patients did not experience a clinically significant event.

"The primary purpose of this review was to ensure our patients are safe and getting the right care," said Dr. Dante Morra, Chief of Staff, Trillium Health Partners. "While this review was specific to a performance issue with one radiologist, the hospital is further strengthening its quality assurance by implementing a formal peer review program within its radiology department."

Dr. Yemen also expanded the initial review mandate to include x-ray and ultrasound tests. The audit determined that these modalities required no further investigation, as no clinically significant events were identified for patients.

Based on these findings, Dr. Yemen has informed the hospital that he has concluded the external review.
