Incidence and predictors of discrepancies in radiology resident interpretations of coronary CT in the emergency department

Abstract Background Discrepancies between preliminary reports by on-call radiology residents and final reports of coronary computed tomography angiography (CCTA) in the emergency department (ED) have not been thoroughly investigated.

description Abstract Background Discrepancies between preliminary reports by on-call radiology residents and final reports of coronary computed tomography angiography (CCTA) in the emergency department (ED) have not been thoroughly investigated. Methods We conducted a retrospective quality assurance analysis of CCTA examinations performed during off-hours in a level-1 ED at a tertiary teaching hospital between March 2020 and April 2022. Discrepancies in identifying significant coronary artery disease (≥ 50% stenosis) between preliminary reports by on-call residents and final reports by board-certified cardiac radiologists were evaluated. Results Among the 766 patient visits (median age, 59 years [interquartile range, 47–70]; 415 men), 82 cases (10.7%) showed discrepancies. Univariable logistic regression analyses identified HEART score, day of ED visit, ED crowding index, and coronary artery calcium (CAC) score as significant factors associated with discrepancies. Multivariable analysis revealed that an ED crowding index < 40 (adjusted odds ratio = 2.06; P = 0.005), and positive CAC scores were independently associated with increased discrepancies (adjusted odds ratio = 4.56 for scores > 0 and ≤ 100, P < 0.001; 4.79 for scores > 100 and ≤ 400, P < 0.001; 3.69 for scores > 400, P = 0.002). The rate of unnecessary invasive coronary angiography was significantly higher in the discrepancy group (80.0%, 12 of 15) compared to the agreement group (14.4%, 16 of 111) (P < 0.05). Conclusions A substantial discrepancy rate was observed between preliminary and final CCTA interpretations in the ED. A lower ED crowding index and positive CAC scores were independently associated with an increased risk of discrepancies.
