Background Given the prevalence and risks of blood transfusion, it is essential that trainees and practicing clinicians have a thorough understanding of relevant transfusion medicine competencies. The aim of this research was to develop and gather validity evidence for an instrument to assess knowledge of core transfusion‐related competencies. Methods We developed the safe transfusion assessment tool (STAT) using a multistep process. Initially, 20 core competencies in transfusion medicine were identified through a consensus‐driven Delphi process. Learning objectives and assessment items pertinent to each competency were created. Next, a 13‐item assessment tool was piloted with multidisciplinary experts and trainees. Multiple iterative revisions were made based on feedback. Finally, the 12‐item STAT was administered to 100 participants of varying training level and specialty to establish validity, difficulty and item discrimination indices, and perceived utility. Results Analysis of instrument item difficulty and item discrimination indices demonstrated the ability of the STAT to assess essential knowledge in transfusion medicine relevant to trainees and clinicians in multiple programs and practice settings. Eight of twelve items discriminated between learners with varying degrees of expertise. Hundred percent of students and trainees rated the STAT as Extremely Helpful or Somewhat Helpful and the majority planned to utilize the answer guide as a study aid. Conclusion The STAT is a concise, valid, and reliable knowledge assessment tool that may be used by researchers and educators to augment transfusion medicine curricula (www.safetransfusion.ucsf.edu). Scores can help inform departments on areas in which trainees require additional support and areas of potential educational interventions.
