ABSTRACT
SETTING AND

PARTICIPANTS:

66 first-year internal medicine residents at Northwestern Memorial Hospital were randomized to Group A or Group B. Curriculum participation was mandatory for all first-year internal medicine residents, but participants were given the option to exclude their answers from the study. DESCRIPTION Prior to 2020, there was no formal radiographic curriculum for internal medicine residents at our institution. Additionally, the COVID pandemic necessitated a paradigm shift in medical education from in-person teaching to remote learning. Accordingly, we created a novel virtual learning curriculum to teach common CXR findings to first-year residents. Objectives of the curriculum include 1) providing first-year residents with a systematic approach to reading and interpreting CXRs, and 2) prompting pattern recognition via proper identification of common CXR findings. We created a randomized cohort study with cross-over design to evaluate the efficacy of our curriculum. First-year internal medicine residents at McGaw Medical Center of Northwestern University were randomized into two groups (Group A/B). In phase I, only Group A was administered the 11-week curriculum. Learners received 2-4 weekly CXRs focusing on a modified ”ABCDE” approach. Each weekly lesson was designed to be completed in 15 mins via smartphone or laptop. Multiple choice standardized assessments were administered before (Pre-Test) and after (Post- Test #1) administration. In phase II, Group B, but not Group A, was given the curriculum;both groups then completed Post-Test #2. This phase assessed curriculum efficacy (Group B) and learning retention (Group A). EVALUATION Independent and paired-sample T tests were used to compare scores between and within groups. Group A scored higher on Post-Test #1 following curriculum administration, compared to on the Pre-Test (pre 44 ± 15%;post 59 ± 17 %;p= 0.005). Group B scored similarly on the Pre-test and Post-Test #1 (pre 50 ± 14%;post 44 ± 17%;p= 0.25), but higher on Post-Test #2, following their curriculum administration (60 ± 17%) than on Post-Test #1 (p= 0.04). There was no statistically significant difference in Post-Test #2 scores between Groups A and B (55 ± 17% and 60 ± 17%, respectively). In Group A, self-assessed confidence with CXR reading was higher at the time of Post- Test #1 than Pre-Test (72 ± 13%;55 ± 12%;p= <0.01). DISCUSSION / REFLECTION / LESSONS LEARNED This study suggests that our novel remote learning curriculum is a practical, effective adjunct to standard residency education for reading CXRs. Notably, residents who received the curriculum demonstrated higher scores and had improved confidence with reading CXRs. Study limitations include small sample size and participant attrition. Future studies include applying our remote learning framework to other imaging studies.
