Clinical Decision Support & Alert Fatigue

Duration: 45 min · Level: Advanced · Module: 9. Quality Reporting & Compliance · Focus: CDS, alert-fatigue, clinical-decision-support, EHR-optimization

Learning objectives

By the end of this lesson you will be able to explain and apply:

  • CDS types
  • Alert fatigue
  • Alert management
  • Meaningful Use/PI requirement
  • Best practice advisories (BPAs)

Why this matters​

Clinical Decision Support (CDS) tools — built into EHR systems — present real-time alerts, reminders, and recommendations to clinicians.

Overview​

Clinical Decision Support (CDS) tools — built into EHR systems — present real-time alerts, reminders, and recommendations to clinicians. They improve safety but are routinely over-ridden. CEHRS specialists often manage alert configuration and monitor override rates.

Key concepts​

Key idea

CDS types: drug-drug interaction alerts, drug-allergy alerts, duplicate order checks, preventive care reminders (flu shot due), quality measure reminders, sepsis screening alerts

  • Alert fatigue: clinicians receive so many EHR alerts that they begin ignoring them; studies show 49-96% of medication alerts are overridden; alert fatigue is a patient safety concern
  • Alert management: CEHRS or clinical informatics staff review alert firing rates and override rates; alerts overridden >90% of the time should be reviewed for appropriateness and potentially retired
  • Meaningful Use/PI requirement: must implement 5 CDS interventions for 5 high-priority conditions plus one drug-drug and one drug-allergy alert; must document clinical quality measure (CQM) reporting
  • Best practice advisories (BPAs): non-interruptive CDS (shown in the sidebar without stopping workflow) vs interruptive (requires clinician action before proceeding); interruptive alerts reserved for highest-risk situations
  • Tracking CDS performance: EHR audit logs capture every alert shown, whether it was accepted or overridden, and the reason given for override; CEHRS can extract this data for quality improvement
