Osler Blood Bank Lecture 2015

2015 marks my 20th year of serving as the primary Transfusion Medicine lecturer for the Osler Institute Pathology Review Course! If you are thinking of attending the course this year and are wondering whether or not I will be presenting the blood bank lectures, this page will give you a bit of information about my schedule for 2015.

Osler has announced the schedule for the Pathology Review course in 2015. I plan to be present to deliver the blood bank review lecture at the February 1-7 course in Los Angeles, and the April 12-18 course in Chicago (I'm not sure yet about the October course in Tampa).

If you are interested, you can download the notes from the 2014 course.

Please believe me when I tell you that I'm not arrogant enough to believe that any of you are sitting at home saying, "If that Chaffin guy ain't talking, I ain't going!", but I just wanted to give you fair warning of when I will and won't be at the individual courses, in case you care! Check back here for updates. Thank you for your understanding.
