ObjectiveTo create a validated tool to measure digital rectal examination proficiency and aid with teaching of the examination.DesignThe Digital Rectal Examination Clinical Tool was created using a modified Delphi method with 5 urologists and 5 radiation oncologists. The instrument was then validated in a population of preclinical medical students examining male urological teaching associates, and clinical trainees (third- and fourth-year medical students and urology resident physicians) examining prospectively enrolled subjects. Trainees completed paired examinations with an attending urologist, and responses were scored with reference to the attending responses.SettingThe instrument was validated at the University of Virginia in the urology clinic, endoscopic operating room, and main operating room settings.ParticipantsWe tested the instrument on consenting subjects consisting of male urologic teaching associates (n = 12), clinic patients (n = 4), and operating room patients (n = 64). The participants were undergraduate (n = 302) and graduate (n = 9) medical trainees.ResultsIn preclerkship trainees, improved scores in subjects without abnormal compared to those with abnormal findings demonstrated validity. In clinical trainees, scores on the Digital Rectal Examination Clinical Tool increased by 2% for each additional year of training, demonstrating construct validity.ConclusionsWe used an expert panel to create a novel instrument for measuring digital rectal examination proficiency and validated it with preclinical and clinical trainee cohorts at our institution.
