Innovations in Medical Education Thursday, October 8, 2015: 12:30 PM Background. The diagnosis of tuberculosis (TB) has evolved with the advent of new diagnostics. It is important for internal medicine (IM) and infectious disease (ID) trainees to effectively diagnose TB, as IM and ID providers are often first to suspect it. We developed and validated an instrument to assess trainees’ ability to obtain and interpret TB diagnostics. Methods. We created an instrument with 10 multiple-choice items based on the US CDC’s Core Curriculum on TB. Ten ID experts reviewed the items for content and accuracy. The instrument was emailed as an online survey using Qualtrics software to 86 IM residents at Johns Hopkins (JH) Hospital and JH Bayview Medical Center, and 43 ID
fellows at JH, Emory, and Vanderbilt. Resident responders were offered a $10 gift card. We used the American Association for Public Opinion Research’s response rate 1 method and performed item analyses. Items were rewritten if they had correct response proportions of 0.95 or point-biserial correlations of
