In order to ease the transition from internship to diagnostic radiology residency, a year-long didactic introduction to radiology course was offered to post-graduate year one (PGY-1) diagnostic radiology residents during their internship, which consisted of 27 hours of lecture over 9 months. The purpose of this study was to determine the quantitative and qualitative educational value of this course and its effect with respect to on-call preparedness.p>
Materials and Methods
<p id="sp0015">Two consecutive cohorts of Diagnostic Radiology residents were included: the first cohort (PGY-1s in 2011–2012) did not participate in the new course (Old Curriculum Residents) and the second cohort (PGY-1s in 2012–2013) completed the new course (New Curriculum Residents). These two cohorts were compared both qualitatively and quantitatively. Scores were compared from the standardized Canadian National Pre-Call Observed Standardized Clinical Examination and American College of Radiology Diagnostic Radiology In-Training examination, which are taken in the PGY-2 year, at months 5 and 7, respectively. In addition, staff observation of on-call resident performance and resident self-reported preparedness were considered. Cohorts were compared using Mann-Whitney U test with significance defined as P value <0.05. P values from 0.05 to 0.10 were noted as possibly significant and further analyzed using a Cohen d test where the difference was determined to be small (0.2), medium (0.5), or large (0.8).p>Results
<p id="sp0020">New Curriculum Residents reported that the content of the PGY1 curriculum was more appropriate than the old curriculum to prepare them for call in PGY2 (P = 0.013). New Curriculum Residents scored better than the Old Curriculum Residents on the Diagnostic Radiology In-Training examination (P = 0.039) and on the emergency cases of the Canadian National Pre-Call Observed Standardized Clinical Examination (P = 0.035). Staff radiologists, who were not blinded, reported that the New Curriculum Residents were better prepared for daytime (P = 0.006) and overnight (P = 0.008) independent call were better prepared to perform common ultrasound examinations alone (P = 0.049), and required less guidance while on call for nine competency areas. There was, however, no statistical difference between the residents' self-reported preparedness for independent call.p>Conclusions
<p id="sp0025">Participation in a lecture-based introductory radiology curriculum during the PGY-1 internship year improved both radiology residents' preparedness for call and their performance in PGY-2.
