Blood Transfusion: Adverse Transfusion Reactions (ATRs)

Blood Transfusion: Adverse Transfusion Reactions (ATRs)

An adverse transfusion reaction (ATR) is an undesirable and unintended physiological response during or after the administration of blood components or plasma derived blood products. It is important for those involved in the transfusion to be capable of early recognition that a reaction may be occurring and proper intervention and management of the reaction.

This module will focus on the various types of ATRs, including the signs, symptoms and treatments. The actions required when an ATR is occurring will also be examined, including notification and reporting.

After completing this module, you will be able to:

  1. Define an adverse transfusion reaction (ATR)
  2. Identify various types of ATR based on the signs and symptoms and time of occurrence.
  3. Identify the reporting framework and process of investigation of ATRs.
  4. Identify the steps to treat and manage each specific ATR.
  5. Determine which transfusion reactions can be resumed once treated.

This continuing professional development (CPD) program has been designed to consider the following roles as defined by the CanMEDS Physician Competency Framework:

  • Medical Expert
  • Communicator
  • Collaborator

MDcme will not release personally identifiable information to a third party without an individual's consent, except such information as is required for reporting purposes to the body or bodies accrediting this course for continuing education study credits. MDcme collects and reviews all course data (registration/course completion statistics, pre/post-test and satisfaction survey) to determine if a course meets participants' learning needs. Data is reviewed to improve existing courses and to inform the development of future course offerings.

Given the importance and potential impact of some courses, evaluation data may be presented and/or published in academic venues. Again, this data is always summarized, with no identifying information included.

At times, a contributing/partner organization involved in a course may request individual participant data from pre/post or evaluation surveys for quality improvement or educational research purposes. This data would be de-identified so would not be associated with any personally identifiable information such as your name, profession, city, etc.

If requested by a contributing/partner organization:
