-Incorrectly labeled patient blood specimens create opportunities for laboratory testing personnel to mistake one patient's specimen for a specimen from a different patient. Transfusion of blood that is typed on specimens that are mislabeled can result in acute hemolytic transfusion reactions.
-To assess the rates of blood bank ABO typing specimens that are mislabeled and/or contain blood belonging to another patient (so-called wrong blood in tube [WBIT]), and to compare these rates with those determined in a similar study performed in 2007.
-Participants enrolled in this College of American Pathologists Q-Probes study for the first quarter of 2015 tallied the number of mislabeled and WBIT ABO blood typing specimens. Outcome measurements were the number of mislabeled and WBIT instances per 1000 specimens. We also evaluated the effects of various practice characteristics, in particular the use of bar coding, on the outcome measurements.
-A total of 30 institutions submitting data on 41 333 ABO blood typing specimens recorded aggregate rates of 7.4 instances of mislabeling (306 specimens) and 0.43 instances of WBIT (10 of 23 234) per 1000 specimens submitted. Mislabeling rates were lower in institutions requiring that specimens be labeled with patients' birth dates than those that did not. The rates of specimen mislabeling and WBIT were otherwise unassociated with any of the other practice variables evaluated.
-The rates of ABO blood typing specimen mislabeling and WBIT are not statistically different from those determined in a similar study performed in 2007 (P = .94 and P = .10). The use of bar coding was not associated with lower mislabeling (P = .80) or WBIT rates (P = .79).
错误标记的患者血液标本会使实验室检测人员有机会将一名患者的标本误认为是另一名患者的标本。对错误标记的标本进行血型鉴定后输血可能会导致急性溶血性输血反应。
评估血库ABO血型鉴定标本错误标记和/或含有其他患者血液（即所谓的管内血型错误[WBIT]）的发生率，并将这些发生率与2007年进行的一项类似研究中确定的发生率进行比较。
参与美国病理学家学会2015年第一季度Q-Probes研究的参与者统计了错误标记和WBIT ABO血型鉴定标本的数量。结果测量指标是每1000份标本中错误标记和WBIT的实例数。我们还评估了各种操作特征，特别是条形码的使用，对结果测量的影响。
共有30个机构提交了41333份ABO血型鉴定标本的数据，记录的总发生率为每1000份提交标本中有7.4例错误标记（306份标本）和0.43例WBIT（23234份中的10份）。要求标本标注患者出生日期的机构的错误标记率低于未要求的机构。标本错误标记率和WBIT率在其他方面与评估的任何其他操作变量均无关联。
ABO血型鉴定标本错误标记和WBIT的发生率与2007年进行的一项类似研究中确定的发生率在统计学上无差异（P = 0.94和P = 0.10）。条形码的使用与较低的错误标记率（P = 0.80）或WBIT率（P = 0.79）无关。
