A pilot study to assess physician knowledge in transfusion medicine

Physician knowledge in transfusion medicine remains an underexplored area. Prior research has shown variability in clinical practices but lacks detailed assessments of knowledge gaps. This study introduces a novel approach to evaluating transfusion-related knowledge. It addresses a gap in understanding how physicians apply transfusion practices. No prior work had resolved the extent of basic knowledge deficiencies. This paper contributes by quantifying correct responses to clinical and basic knowledge questions. The regional and specialty distribution of responses was also examined. These findings may guide future educational interventions.

The study aimed to evaluate physician knowledge in transfusion medicine. It focused on both clinical application and basic knowledge of blood products. The researchers sought to identify areas of weakness in transfusion practices. They also aimed to assess how physicians approach transfusion decisions. This was done through a structured questionnaire with 55 questions. The form was distributed across Canada via the Canadian Society for Transfusion Medicine. The goal was to gather responses from a diverse physician population. The results could inform targeted educational efforts.

The study used a 55-question survey to assess transfusion knowledge. The survey covered clinical use and basic information on blood products. It was distributed through the Canadian Society for Transfusion Medicine. Regional distribution was managed by designated individuals. Some provinces used mailing lists, others used hospital-based distribution. The survey was available in English and French, with 500 French forms. Responses were categorized as correct, incorrect, no answer, or with comments. A total of 294 completed forms were returned for analysis.

Of the 294 returned forms, 52% of questions were answered correctly or with qualifying comments. Clinical practice questions had a higher accuracy rate of 63%. Basic knowledge questions were correct in only 37% of cases. The volume of an apheresis plasma unit was correctly estimated by less than 10%. Many respondents underestimated the volume by 300-400 mL. Anaesthesiologists submitted the most responses, at 21%. Haematologists contributed only 4% of the total. Ontario and British Columbia provided the highest response rates at 30% and 22%, respectively.

The study suggests that clinical transfusion decisions are often accompanied by critical thinking. Physicians generally do not rely solely on rote memorization. However, basic knowledge of transfusion products remains limited. The low accuracy in estimating apheresis plasma volume is a notable issue. The authors propose that educational efforts should target basic transfusion concepts. The regional and specialty differences in response rates may inform future outreach. The study highlights the need for improved knowledge in transfusion medicine. These findings may guide the development of targeted training programs.
