Autologous donation error rates in Canada.
BACKGROUND
Although certain transfusion risks are eliminated by the use of autologous blood, clerical errors may still occur. In addition, because of differences in donor selection criteria and donor-patient expectations, the consequences of certain errors may be different in autologous and allogeneic donations.


METHODS
In January 1996, autologous donation error rates in Canada from 1989 to November 1995 were estimated by 1) a detailed questionnaire sent to hospitals supplied by the Canadian Red Cross, Blood Services, Transfusion Center of Quebec at Montreal autologous donation program (n = 31), 2) a review of that institution's quality assurance non-compliance reports, and 3) a detailed questionnaire sent to other Canadian Red Cross centers with autologous donation programs (n = 16) and hospital-based autologous programs in Canada (n = 3). The total number of autologous donations collected was determined from Canadian Red Cross annual reports and information supplied by hospital-based programs.


RESULTS
There were 113 errors reported for 16,873 units collected by the Montreal center (1/149 units) based on collection center and hospital data. The most frequent errors were the late receipt of units for surgery (25% of errors) or the receipt of units in the wrong hospital (23%). Other Canadian programs reported 166 errors for approximately 53,500 units collected (1/322 units). However, this figure was based mainly on collection center, and not hospital, data. The most frequent errors were in labeling (48%) and component preparation (25%). One unit of autologous fresh-frozen plasma was transfused to the wrong recipient. Errors were more frequent if components were produced, if units were drawn in hospitals for interhospital transfer, or it units were shipped between Red Cross centers.


CONCLUSIONS
Errors are not infrequent in autologous donation programs. Autologous transfusion should not be considered as being without risk.
