The use of multiple-choice questions in medical assessments is ubiquitous and extends in breadth from undergraduate formative and summative assessments to postgraduate certifications and reaccreditations. Despite the clear importance of multiple-choice questions in medicine, in the last thirty years there has been no authoritative peer reviewed publication that reviews the overall generation and use of multiple-choice questions in medicine.
