Blood Bank and Transfusion Medicine
Duration: Two Months
Rotation Director(s): Patricia Carey, MD
Faculty/ Instructor(s):
Pam Inglish, MT(ASCP)SBB, Margaret Simon
Description of Rotation
During the rotation the resident completes program objectives by rotating through the various areas of the blood center. After the first six weeks, the resident is placed on the on-call schedule for one week with a staff physician available at all times for backup. The pathology resident rotation at Hoxworth Blood Center is subdivided into the various areas that constitute the blood center.
These include: Donor Services, Transfusion Service and Immunohematology Reference Laboratories, Transfusion Service, Donor Testing Laboratory, Components Laboratory, Transplant Immunology Division, Cellular Therapies Division, Donor Recruitment and Community Relations and Blood Center Administration. Goals and objectives for each of these specific areas are provided.
In addition to the rotations, the resident is expected to attend Apheresis Rounds, Tuesday Rounds at MSB, Journal Club and Clinical Update meetings, the Leadership Team Meeting and other meetings including Medical-Technical Advisory Committee and Transfusion Committee as these meetings are scheduled. The resident is encouraged to attend lectures in the graduate program and other learning opportunities, including teleconferences and special lectures.
Finally, the resident is expected to make a presentation to the staff at the end of the rotation. The resident will select his/her own topic that relates to blood transfusion medicine. Additionally, the resident will take a written examination during the last week of the rotation.
