Patient Safety

The objective of the Transplantation Safety Outcomes Group (TSOG) is to study the systems and processes of transplant care systematically, comprehensively and prospectively.

The areas of interest include:

  • Identification of patient safety risks
  • Assessment of the effectiveness of regulatory guidelines
  • Organizational workflow optimization and safety
  • Development of safety metrics for performance measurement
  • Clinician communication
