Consent for blood transfusion: How is it understood by transfusion candidates / 中国输血杂志

ABSTRACT

【Objective】 To assess the sufficient information got by the informed transfusion recipients from the consents for blood transfusion and to explore the influencing factors, so as to provide scientific evidences for patients to comprehend the consent better. 【Methods】 A cohort study using questionnaire was conducted among 198 patients who received red blood cell transfusion from April 2019 to June 2019 in a tertiary hospital. 18 options were investigated, including basic information of patients, recall of the informed consent process performed by physicians and how well they comprehend the information. SPSS 23.0 statistical software was used for data statistical processing. 【Results】 All 198 questionnaires were returned and valid (100%, 198/198). The score of 198 informed transfusion recipients was 2~9 (5.293±1.549), and the score of Internal Medicine and Surgical transfusion patients was 6.07±1.77 vs 6.07±1.77 (P<0.05). Univariate comparative analysis showed that the clinical department, age, education background, instructions, including its time and identity of instructors, before transfusion were the variables that affected the comprehension of informed patients (P<0.05). Linear regression analysis indicated that the clinical department, pre-transfusion instruction and its time were independent influencing factors on the comprehension(P<0.05). The top 3 poorly-understood items included auto-transfusion, alternative transfusion therapy and 1-year donation deferral after blood transfusion. 【Conclusion】 More efforts are needed to help transfusion candidates to comprehend consent for blood transfusion better since their knowledge varied with clinical departments. Physicians′ transfusion knowledge and communication skills also need to be enhanced to provide targeted and multi-form informing methods.
