A pilot study to assess physician knowledge in transfusion medicine

Summary Introduction An assessment of transfusion medicine knowledge and practice in Canada was carried out over a 3‐week period. Methods Fifty‐five questions were posed to evaluate both basic information on blood and blood products and on clinical use. The form was distributed through the Canadian Society for Transfusion Medicine with designated individuals asked to handle regional distribution. Some used provincial mailing lists, others distributed within each hospital. Approximately, 2000 forms were sent, including 500 in French. Results A total of 294 forms were returned; answers were recorded as ‘correct’, ‘incorrect’, ‘no answer’ or with ‘added comments’. Overall, 52% of the questions were answered correctly or were answered with qualifying comments. In clinical practice questions, 63% were answered correctly or with qualifying comments. Basic knowledge questions drew correct answers in 37% of the cases. Several issues were answered poorly. The volume of an apheresis plasma unit was correctly estimated by less than 10% of respondents with many understating the volume (500–600 mL) by as much as 300–400 mL. Anaesthesiologists responded most often (21%); few haematologists participated (4%). Provincial response varied: most were received from Ontario (30%) and British Columbia (22%). Conclusions The answers show that clinical application of transfusion is generally accompanied by a questioning process – it is not entirely by rote. Basic knowledge about products needs improvement.
