Report IDs for mismatches of blood product and recipients. Counted is the number of errors as opposed the number of mismatched patients or blood products: The number of subjects concerned with this problem is different from the number of errors, i.e. one mismatch concerns frequently a second patient. Percentage given is the rate of all incidents (see table 3).
