OBJECTIVES: To (1) describe knowledge, attitudes, and reported practice of blood transfusion of nurses in Aquitaine's hospitals; (2) measure the potential threat for patient safety of poor transfusion-related knowledge and practice; and (3) identify factors associated with poor knowledge and practice. DESIGN: Survey conducted in 14 hospitals in Aquitaine (one university and 13 general hospitals). SETTING: Hospitalized care. PARTICIPANTS: A random sample of nurses. MATERIALS: Data were collected anonymously by investigators through structured individual interviews. The questionnaire contained mainly knowledge and practice questions about blood transfusion regulation. MAIN OUTCOME MEASURES: Hazardous knowledge and practice scores have been constructed, reflecting the levels of potential danger in the answers to the questionnaire. Factors associated with these scores have been studied using a random-effect linear regression. RESULTS: In our sample of 1090 nurses, poor knowledge and practice concerned mainly (1) the bedside blood compatibility test [proportion of responses (PR) with potential life threat between 12.7 and 35.5%]; (2) pre-transfusion compatibility check when receiving blood units (PR = 34.5%); (3) delay between screening of red cell antibodies and transfusion (PR = 20.5%); (4) delay in preservation of blood unit in the ward (PR = 33.4%); and (5) recognition of abnormal reactions after transfusion (PR = 47.1%). Frequency of transfusion and training were the factors most strongly associated with hazardous knowledge and practice scores. CONCLUSION: Low training and transfusion activity were key determinants of poor transfusion-related knowledge and practice.
