Modern Blood Banking & Transfusion Practices 6 th Edition Tissue Bank Oversight § Physician-appointed Medical Director investigates adverse outcomes, participates in lookback investigations, approves SOPs with any deviations, and interfaces with end users. § Development of a tissue committee is recommended with the intent to ensure and promote best practices based on evidencebased medicine.

Modern Blood Banking & Transfusion Practices Acquisition of Allografts and Inventory 6 th Edition § The Tissue Bank should approve tissue vendors and receive all shipments. § Tissue receipt records must contain, at a minimum § § § Name and address of tissue supplier Description of tissue and quantity Date of tissue receipt Condition of tissue upon receipt Expiration date (if applicable) Tissue Identification Number (TIN) Copyright © 2012 F. A. Davis Company

Modern Blood Banking & Transfusion Practices 6 th Edition Storage § Storage conditions vary between the different tissue types. § Follow the tissue vendor’s recommendations for each specimen. § The Joint Commission and AATB require that tissue storage and distribution be in conformance with guidelines.

Modern Blood Banking & Transfusion Practices 6 th Edition Autologous Tissue § Autologous tissue is any tissue that is removed from a patient with the intent to reimplant it at a later date. § Within the operating room, the preparation falls under the regulatory standards of the JC, the AATB, and the Association of peri. Operative Registered Nurses (AORN). Copyright © 2012 F. A. Davis Company

Modern Blood Banking & Transfusion Practices 6 th Edition Adverse Events § Negative changes, unexpected outcomes, or reactions to the tissue implant § Can be due to infectious disease, failure of the allograft to function as expected, or transmission of malignancy § Necessary to report adverse events for the protection of other patients who may receive tissue from the same donor § Vary with the nature of the tissue involved Copyright © 2012 F. A. Davis Company

Modern Blood Banking & Transfusion Practices 6 th Edition Adverse Events (cont’d) § Similar to blood donation, the first step in ensuring safe tissue is to screen the donor population for individuals with low risk of disease. § Discovery of the source of tissue failure will lead to recall of other products that may have potential to harm other patients. Copyright © 2012 F. A. Davis Company

Modern Blood Banking & Transfusion Practices 6 th Edition Adverse Events: Reporting and Investigating § The most basic step in the reporting process is recognition of an adverse event by the clinical staff. § The Medical Director of the Tissue Bank should communicate regularly with the surgeons involved. § Every complaint or suspicion should be taken seriously, even if there is a low chance that the event is related to tissue transplant.
