채혈 시 환자가 인지하는 혈액형 확인: 정확한 환자 확인 및 ABO 검사를 위한 추가 단계 = Checking Perceived Blood Group of the Patient Upon Phlebotomy: Additional Approach for Accurate Patient Identification and ABO Testing

다국어 초록 (Multilingual Abstract)

Background: Accurate patient identification is fundamental in transfusion medicine. Our hypothesis is that an openquestion about patients’ ABO blood group would be helpful for accurate identification of the patient and for accuratelaboratory testing.
Methods: We added some blanks, including the patient’s ABO blood group on the tube label, which should befilled in by the phlebotomist on the spot. From Aug 1, 2012 to May 31, 2013, we analyzed the effect of theadditional step for identification of a misidentification ‘incident’ in 31,454 tests of 14,864 patients. We surveyedon 21 phlebotomists with regard to whether the changed label reinforces patient identification. In addition, thediscrepancy rate between the ABO blood group perceived by the patient and the test result was analyzed.
Results: Patient-misidentification error rate during this study was 0.022%, and 81.0% of the phlebotomistsanswered that the changed label reinforces patient identification. The total discrepancy rate was 1.93%. Patientswithout previous results showed a higher discrepancy rate (3.08%) than patients with previous results (0.35%).
Males (2.48%) showed a higher discrepancy rate than females (1.38%). Patients older than 50 years showed ahigher discrepancy rate (2.87%) than patients younger than 50 years (0.82%). According to ABO blood group,group O showed the lowest discrepancy rate (0.87%).
Conclusion: Checking ABO blood group known by the patient helped phlebotomists to correctly identify theintended patient. Active corrective action by the transfusion laboratory when discrepancies exist could increasetest reliability and pave the way for safe transfusion, which will ultimately improve the quality of transfusionmedicine.
