Report of the 2007 Annual Survey AATB-accredited Tissue Banks in Canada
When referencing information or data from this presentation, use the following citation: 2007 American Association of Tissue Banks (AATB) Annual Survey of Accredited Tissue Banks in Canada. McLean, VA: AATB, 2010.
7 Survey Participants All are Tissue Banks in Canada accredited by AATB o All of them recover, process, store and distribute tissue o 5 Tissue Banks were inspected by agencies in 2007 3 AATB 4 ISO 1 CAP 1 Other (identity not specified)
Was your tissue bank inspected in 2007? Yes = 5 (71.4%)
Recovery How many tissue donors did your Tissue Bank recover for transplantation? Total = 795 o Deceased = 50.3% How many had an autopsy performed? 35% o Living = 49.7% How many tissue donors were also organ donors? 28.8% How many tissue donors were also ocular donors? 33.8%

# of Tissue Banks = 7 o Process bone = 6 o Process soft tissue = 6 o Process skin = 4 o Process cardiac and/or vascular = 4 o Process tissue from Living Donors = 4 ? Total donors processed = 665 Average graft yield per donor = 21 Processing
# of Musculoskeletal Donors = 233 o Bone = 295 o Cartilage = 1 o Osteoarticular (fresh) = 5
# of Soft Tissue Donors = 174 o Tendons = 138 o Ligaments = 24 o Fascia = 129 o Pericardium = 5 Processing
# of Cardiac and/or Vascular Donors = 170 o Heart Valves = 146 o Non-valved conduits = 44 o Artery = 1 Processing
# of Skin Donors = 146 o Thin = 144 o Thick = 2 Processing
Use of Radiation No Tissue Banks treated tissues with radiation prior to processing (non-terminal irradiation). 1 Tissue Bank treated tissues with Gamma radiation (above 2.5 Mrads) as a final treatment. Musculoskeletal and soft tissue grafts were primarily treated with antibiotics during processing.
Infectious Disease Testing

Of those who did, these %s are from their experience.
All 7 Tissue Banks distributed tissue from deceased donors: Soft tissue = 7 MS = 6 Cardiac = 4 Skin = 4 5 Tissue Banks distributed tissue from living donors. 99% of tissues were distributed directly to Hospitals/Medical Facilities.
