Does AI-assisted chart review reduce screening time compared to manual chart review for identifying AMICS patients?
AI-assisted chart review using NLP significantly reduces screening time for identifying AMICS patients for registry inclusion while maintaining 100% diagnostic accuracy compared to manual review.
Effect estimate: Median difference 1:03 minutes (95% CI 0:57-1:11)
p-value: p=<0.001
INTRODUCTION: The Danish RETROSHOCK registry has provided valuable insights into patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) and their clinical trajectories. However, continuously updating the registry through manual chart review is time-consuming. METHODS: Electronic medical records were retrieved from patients admitted to Odense University Hospital from 2018 to 2022, assigned an ICD-10 code suggestive of AMICS. A random sample of 100 consecutive patients was selected for testing the AI-assisted chart review. The AI tool was a natural language processing model identifying AMICS-related keywords. Electronic medical records were initially screened using AI-assisted chart review, with time recorded until AMICS diagnosis or exclusion due to an alternative diagnosis. One week later, a manual chart review was performed. AI-assisted and manual screening times were compared using the Wilcoxon signed-rank test. RESULTS: AI-assisted chart review identified the same 26 AMICS patients as manual review (Cohen's kappa = 1). Median manual inclusion time was 2:20 minutes, compared with 1:16 minutes with AI-assisted chart review (p less-than 0.001). Median manual exclusion time was 2:45 minutes, and AI-assisted exclusion was 0:59 minutes (p less-than 0.001). CONCLUSIONS: AI-assisted chart review significantly reduced screening time for including AMICS patients in the RETROSHOCK registry and excluding non-eligible patients, while preserving diagnostic accuracy. FUNDING: The RETROSHOCK database is supported by Johnson and Johnson Med Tech and the Novo Nordic Foundation. TRIAL REGISTRATION: Not relevant.
Jeppesen et al. (Wed,) conducted a observational in Acute myocardial infarction complicated by cardiogenic shock (AMICS) (n=100). AI-assisted chart review (NLP model) vs. Manual chart review was evaluated on Median time to inclusion (Median difference 1:03 minutes, 95% CI 0:57-1:11, p=<0.001). AI-assisted chart review significantly reduced the median screening time for including AMICS patients by 1:03 minutes compared to manual review, while maintaining complete diagnostic concordance.
