Why the study?

Does emergency physicians' interpretation of ECGs concord with cardiologists' interpretation and impact patient management?

Population

300 consecutive emergency department electrocardiograms (ECGs) at an urban university hospital

Comparison

Emergency physicians' interpretation of ECGs vs Blinded interpretation by a staff cardiologist

Design

Cross-sectional, Second interpretation by a staff cardiologist was blinded

Discussion

Member takes

Implication

Discordance rarely alters management; leaves open whether targeted ECG training improves accuracy in prospective studies.

Key Points

To determine the concordance of emergency department electrocardiogram interpretations between emergency physicians and cardiologists, and to assess the impact of misinterpretations on patient care.
Conducted a prospective study analyzing 300 consecutive emergency department electrocardiograms (ECGs) at an urban university hospital using standardized response forms.
Compared emergency physician readings against blinded secondary interpretations by staff cardiologists as the reference standard to evaluate clinically important errors.
Inter-observer concordance was weak at 0.69 (overall Kappa = 0.32, weighted Kappa = 0.30) with statistically significant discordance (McNemar Chi-square P < 0.05).
Investigators identified 154 interpretation errors (nine with probable clinical significance, 56 with indeterminate significance), with error rates remaining consistent across physician training levels.
ECG misinterpretations altered patient management decisions in only two cases without affecting patient outcomes, predominantly involving repolarization abnormalities, ventricular hypertrophy, and hemi-blocks.

Structured PICO

Does emergency physicians' interpretation of ECGs concord with cardiologists' interpretation and impact patient management?

Population

300 consecutive emergency department electrocardiograms (ECGs) at an urban university hospital

Intervention

Emergency physicians' interpretation of ECGs

Comparator

Blinded interpretation by a staff cardiologist (assumed correct)

Outcome

Concordance of emergency physicians' and cardiologists' interpretations of ED ECGs

While there is significant discordance between emergency physicians and cardiologists in ECG interpretation, these errors rarely impact patient management or outcomes.
