Involvement of transfusion unit staff in the informed consent process

Abstract

Background and objectives: Obtaining informed consent (IC) for a blood transfusion is an absolute requirement. In this study, we compared the depth of understanding of blood transfusion among patients with or without an explanation by the transfusion unit staff and evaluated the usefulness of this intervention in obtaining IC.

Materials and methods: Expert staff from the transfusion unit started to provide patients with a basic explanation of blood transfusion (intervention group, n = 129). The efficacy of this strategy was assessed by comparison with explanation given by the primary doctors only (conventional group, n = 31). We performed a questionnaire survey to analyze the length of time spent providing information of blood transfusion and the depth of understanding of blood transfusion in the two groups.

Results: The median time in providing information in the conventional and intervention groups was 6 and 20 minutes, respectively (P < 0.0001). Patients in the intervention group had a better understanding of several key points on blood transfusion than those in the conventional group.

Conclusion: Our results show that expert staff from the transfusion unit should be involved in obtaining IC for a blood transfusion. Patients who were provided information by transfusion unit staff were more likely to have a better understanding of the risks and benefits of transfusion.
