Overview

Randomized trial evaluates diagnostic accuracy of clinician data in ICU via interruptive alerts, suggesting improvements for CDS tools.

Key Points

  • The study aims to evaluate the diagnostic accuracy and timing of clinician responses using interruptive alerts in the electronic health record.
  • Implementing a provider-facing interruptive alert in an ICU setting at Vanderbilt University Medical Center.
  • Collecting data from clinicians regarding 6 diagnoses for patients on mechanical ventilation.
  • Comparing accuracy and timing of responses between cohorts with and without a 'defer' option.
  • Clinicians answered the alert about diagnoses on 110 patients; time taken was 175 minutes with defer vs 7 minutes without (p < 0.001).
  • Accuracy of diagnoses was similar: 5.6 correct in the Delay cohort vs 5.6 in the No Delay cohort (p = 0.67).
