目的探讨品管圈(QCC)活动降低临床血标本不合格例数的应用效果。方法成立心血圈,按照QCC活动步骤,对检验科、输血科血标本不合格例数进行原因分析,制定并实施改善对策,对比QCC改善前后血标本不合格例数。结果对照组中检验科460例,血液凝固372例,占80.87%;输血科54例,《输血申请单》信息不完整38例,占70.37%。观察组中检验科、输血科不合格血标本共391例,下降23.93%。其中检验科349例,血液凝固246例,占70.49%;输血科42例,《输血申请单》信息不完整18例,占42.86%。与对照组比较,观察组检验科不合格血标本中血液凝固占的比率下降(χ~2=11.861,P<0.05);输血科不合格血标本中《输血申请单》信息不完整所占比率下降(χ~2=7.358,P<0.05)。结论开展品管圈活动能有效降低临床血标本不合格例数,提高血标本采集质量和患者满意度,保证了血标本检验前的质量安全。
Objective To investigate the effect of reducing the number of substandard clinical blood samples by QCC activities. Methods A heart circle was established. According to the steps of QCC activities, the reasons for the number of unqualified blood samples in the laboratory and blood transfusion departments were analyzed, and the improvement measures were formulated and implemented. The number of unqualified blood samples before and after QCC improvement was compared. Results In the control group, there were 460 cases of laboratory examination, 372 cases of blood coagulation, accounting for 80.87%; 54 cases of blood transfusion, and 38 cases of incomplete information on blood transfusion request, accounting for 70.37%. In the observation group, there were 391 cases of failed blood tests in blood test department and blood transfusion department, a decrease of 23.93%. Among them, 349 cases were laboratory and 246 cases were blood coagulation, accounting for 70.49%; 42 cases were blood transfusion, and 18 cases were incomplete with 42.86% incomplete information of transfusion application form. Compared with the control group, the rate of blood coagulation in the unqualified blood test group in the observation group decreased (χ ~ 2 = 11.861, P <0.05). The percentage of incomplete blood transfusion request information in the blood transfusion substandard blood samples Decreased (χ ~ 2 = 7.358, P <0.05). Conclusion Carrying out QC activities can effectively reduce the number of non-conforming clinical blood samples, improve blood collection quality and patient satisfaction, and ensure the quality and safety of blood samples before testing.
