目的研究临床送检病原学标本不合格的原因,提出改进对策。方法通过回顾性分析方法,对2011年本医院住院患者临床送检的病原学标本不合格原因进行研究与分析。结果全年发现不合格病原学标本1 102例,不合格率为20.64%,其中痰标本占不合格标本的57.44%。主要原因是采集方法不当,痰标本中混入杂质、血液标本污染等。结论临床送检病原学标本不合格率过高,主要是采集方法不当,应加强采集标本方法的培训。
Objective To study the causes of unqualified clinical specimens for etiological examination and propose the improvement measures. Methods By retrospective analysis, the causes of unqualified etiological specimens of clinical inpatients in our hospital in 2011 were studied and analyzed. Results A total of 1 102 cases of unqualified etiological specimens were found in the year, with a failure rate of 20.64%. Among them, sputum specimens accounted for 57.44% of unqualified specimens. The main reason is improper collection methods, sputum samples mixed with impurities, blood samples and so on. Conclusions The failure rate of clinical specimens for etiological diagnosis is too high, which is mainly due to the improper collection methods. Training on the method of collecting specimens should be strengthened.
