UNLABELLED: Scand J Caring Sci; 2010; 24; 581-591 Blood sample collection and patient identification demand improvement: a questionnaire study of preanalytical practices in hospital wards and laboratories
Most errors in venous blood testing result from human mistakes occurring before the sample reach the laboratory.
To survey venous blood sampling (VBS) practices in hospital wards and to compare practices with hospital laboratories.
Staff in two hospitals (all wards) and two hospital laboratories (314 respondents, response rate 94%), completed a questionnaire addressing issues relevant to the collection of venous blood samples for clinical chemistry testing.
The findings suggest that instructions for patient identification and the collection of venous blood samples were not always followed. For example, 79% of the respondents reported the undesirable practice (UDP) of not always using wristbands for patient identification. Similarly, 87% of the respondents noted the UDP of removing venous stasis after the sampling is finished. Compared with the ward staff, a significantly higher proportion of the laboratory staff reported desirable practices regarding the collection of venous blood samples. Neither education nor the existence of established sampling routines was clearly associated with VBS practices among the ward staff.
The results of this study, the first of its kind, suggest that a clinically important risk of error is associated with VBS in the surveyed wards. Most important is the risk of misidentification of patients. Quality improvement of blood sample collection is clearly needed, particularly in hospital wards.

静脉血检测中的大多数错误源于样本送达实验室之前发生的人为失误。
调查医院病房的静脉血采样（VBS）操作，并将其与医院实验室的操作进行比较。
两家医院（所有病房）和两家医院实验室的工作人员（314名受访者，回复率94%）完成了一份问卷，该问卷涉及与临床化学检测静脉血样本采集相关的问题。
研究结果表明，患者识别和静脉血样本采集的指导并非总是得到遵循。例如，79%的受访者报告了不总是使用腕带进行患者识别的不良做法（UDP）。同样，87%的受访者指出采样完成后消除静脉淤血的不良做法。与病房工作人员相比，实验室工作人员中报告在静脉血样本采集方面有良好做法的比例显著更高。教育程度和既定采样程序的存在与病房工作人员的VBS操作均无明显关联。
这项同类研究的结果表明，在所调查的病房中，VBS存在临床上重要的错误风险。最重要的是患者身份识别错误的风险。显然需要改进血液样本采集的质量，尤其是在医院病房。
