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

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).

LaNasa et al. (2026) studied this question.
