Abstract

Objectives: In the light of a rapidly increasing use of POCT blood gas testing, where tests and interpretation are performed by non-laboratory personnel, the objective was to investigate the knowledge among personnel in the Nordic countries using blood gas analyzers with focus on the interference from hemolysis.

Methods: Information was obtained from a self-developed, pre-tested online questionnaire. The questions covered demographic information about the respondents and specific questions on handling of and knowledge about blood gas analyses and the impact of hemolysis. The questionnaire was distributed by e-mail to relevant colleagues on behalf of the Nordic preanalytical scientific working group under the Nordic Federation of Clinical Chemistry.

Results: A total of 117 respondents completed the questionnaire. 62.7 % respondents both used the analyzer and interpreted the results. 59.6 % respondents did not know to which degree the blood gas analyzer can identify hemolysis. 4.4 % answered that all levels or high levels of hemolysis can be detected. 3.9 % considered the result valid despite hemolysis if it is released from the instrument. 73.7 % of all respondents knew that hemolysis alters potassium measurements, while knowledge about the effect on PaO2 and bicarbonate measurements were more divergent.

Conclusions: The knowledge about blood gas analyzers with focus on the interference from hemolysis is sparse among non-laboratory personnel using the blood gas analyzers. This emphasizes the need for better education and competence management, which perhaps is even more important for these analyses than for other point-of-care tests.

临床人员对使用血气分析仪溶血影响的了解。
目的:鉴于POCT血气检测的使用迅速增加,其中检测和解释由非实验室人员进行,目的是调查北欧国家人员使用血气分析仪的知识,重点是溶血的干扰。方法:采用自行设计、预测的在线问卷。问题包括受访者的人口统计信息,以及有关血气分析和溶血影响的处理和知识的具体问题。问卷是代表北欧临床化学联合会下属的北欧分析前科学工作组通过电子邮件分发给相关同事的。结果:共117名被调查者完成问卷。62.7 %的受访者既使用分析器又解释结果。59.6 %的受访者不知道血气分析仪能在多大程度上识别溶血。4.4% 回答所有水平或高水平溶血都可以检测到。3.9 %认为结果有效,尽管溶血,如果它是从仪器释放。73.7 %的受访者知道溶血会改变钾的测量值,而对PaO2和碳酸氢盐测量值的影响的认识则更为分歧。结论:在使用血气分析仪的非实验室人员中,对血气分析仪以及溶血干扰的知识知之甚少。这强调了对更好的教育和能力管理的需要,这对这些分析来说可能比其他即时测试更重要。
