Can emergency physicians reliably interpret cardiac CT images? A prospective observational study

Emergency physicians frequently interpret cardiac CT scans despite limited training in cardiovascular imaging. While radiologists are typically responsible for such assessments, the urgency of acute chest pain cases often leads emergency physicians to act on their own interpretations. Prior research has shown that this practice is common but lacks systematic validation. No prior work had resolved whether emergency physicians can reliably interpret cardiac CT images. This gap motivated a study to evaluate the agreement between emergency physicians and radiologists in interpreting cardiac CT scans. The critical nature of these decisions requires understanding the reliability of emergency physicians' assessments.

This study aimed to determine whether emergency physicians can reliably interpret cardiac CT images when compared to radiologists. The specific problem addressed is the lack of evidence on the accuracy of emergency physicians' interpretations of cardiac CT scans. The motivation stems from the clinical reality that emergency physicians often act on their own interpretations despite limited training in cardiovascular imaging. The researchers propose that emergency physicians may need additional education before independently interpreting cardiac CT scans. The study sought to quantify the level of agreement between emergency physicians and radiologists in assessing coronary stenosis and plaque calcification.

The study sought to quantify the level of agreement between emergency physicians and radiologists in assessing coronary stenosis and plaque calcification.

The study used a prospective observational design to evaluate emergency physicians' interpretations of cardiac CT scans. Participants were emergency physicians with at least one year of experience in interpreting cardiac CT scans. All participants underwent a one-hour training session before the study. The primary outcome was the agreement between emergency physicians and radiologists in assessing coronary stenosis and plaque calcification. The most significant lesion in each arterial segment was evaluated by both groups. Agreement was measured using Cohen's kappa and Gwet's AC1 statistics. A total of 103 patients were enrolled, with 412 arterial segments analyzed. The researchers propose that emergency physicians may need additional education before independently interpreting cardiac CT scans.

Out of 412 arterial segments analyzed, emergency physicians and radiologists agreed on stenosis grading in 363 segments (88.1%). The interrater agreement was good, with a kappa value of 0.6439 and an AC1 value of 0.8810. For plaque calcification, agreement was observed in 354 segments (86.6%), with a kappa of 0.5660 and an AC1 of 0.8501. However, in 6 segments with significant stenosis reported by radiologists, emergency physicians classified them as non-significant or clear. Subsequent invasive coronary angiography confirmed the radiologists' assessments. The researchers propose that emergency physicians may need additional education before independently interpreting cardiac CT scans. These findings suggest that while agreement is generally good, there are critical discrepancies in some cases.

The authors suggest that emergency physicians can generally interpret cardiac CT scans with good agreement on stenosis and plaque calcification. However, there are notable discrepancies in certain cases, particularly in identifying significant stenosis. The researchers propose that emergency physicians may need additional education before independently interpreting cardiac CT scans. The study does not claim that emergency physicians are fully reliable in all cases. The findings suggest that current training may be insufficient for independent interpretation in all scenarios.
