AlertDx: A Clinical Backstop

AI-powered secondary review that catches diagnostic errors before they cause harm. AlertDx provides an extra layer of safety for clinical decisions.

The Diagnostic Error Problem

7.4M
Annual ED misdiagnoses in the US
2.6M
Result in patient harm
23%
Hospital deaths/ICU transfers linked to diagnostic errors

Cognitive Factors Behind These Errors

Research identifies predictable patterns of human cognition under stress:

  • Premature closure—settling on a diagnosis too early
  • Failure to order or follow up appropriate tests
  • Over-reliance on others' findings or opinions
  • Misjudging the significance of clinical findings
  • Incomplete history and physical examinations

These errors occur across all experience levels and are particularly common during care transitions.

How AlertDx Works

Event-triggered analysis highlighting conditions to consider

1

Monitors Clinical Events

AlertDx receives clinical events from the EMR:

  • Admissions & Discharges
  • Vital Signs & Lab Results
  • Medications & Procedures
  • Clinical Notes & Orders
  • Consultations & Transfers
2

Retrieves Clinical Data

Clinical data is retrieved from multiple EMR systems (Epic, Cerner, Allscripts, Meditech) via HL7 or FHIR and processed for analysis. This includes patient history, vitals, labs, medications, and clinical notes.

3

Applies AI Analysis

Large language models with extended reasoning analyze the full clinical context—not just rules or thresholds. The system identifies patterns that correlate with missed diagnoses.

4

Generates Structured Alerts

When potential risk is identified, AlertDx produces alerts with conditions to consider and supporting clinical reasoning.

5

Delivers to Clinicians

Alerts are delivered to clinicians through configurable integration with your EMR interface during active patient encounters.

AlertDx (analysis as of 3 minutes ago)

Consider: Pulmonary Embolism

More Info: Tachycardia, though modest, in combination with marginal pulse oximetry reading of 94% warrants consideration of pulmonary embolism.

Pulmonary Embolism:

Tachycardia HR 102 SpO2 94% Dyspnea Pleuritic chest pain Leg swelling Recent immobilization

Further evaluation might include D-dimer, pulmonary angiography
