Brief Summary

Hospital-acquired blood clots (HA-VTE) are the leading cause of death in hospitalized patients in the US. Each year, about 900,000 people get blood clots, costing between $7 and $10 billion in medical expenses. HA-VTE is the second leading cause of long-term disability and causes significant health issues and deaths in both adults and children. About 1 in 3 people who get blood clots experience long-term complications. Reducing HA-VTE is a major challenge. This study will test a new AI method to predict and prevent HA-VTE. The goal is to see if this AI tool can reduce the number of HA-VTE cases in the Vanderbilt Health System, which includes both urban and rural hospitals. The AI tool, called VTE-AI, calculates a risk score without needing input from doctors. It will suggest reconsidering blood clot prevention measures for patients who don't have them ordered and have no reasons to avoid them. This suggestion will be made after admission and daily during the hospital stay. Currently, doctors manually calculate a risk score and choose a prevention option. This study will compare the effectiveness of the AI tool against the current manual method in reducing HA-VTE cases. The study will randomly assign half of the patients to use the AI tool and the other half to the standard manual method.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Hospital Acquired VTE

    Percentage of admissions in which patients were diagnosed with VTE more than 48 hours after admission, defined as "Hospital Acquired" in prior literature

    Baseline to discharge from hospital, approximately 2 to 5 days

Secondary Outcomes (3)

  • Thirty-day hospital readmissions

    Day 30 following hospital discharge

  • Bleeding events

    Baseline to discharge from hospital, approximately 2 to 5 days

  • Length of Stay

    Date of admission to date of discharge from hospital, approximately 2 to 5 days

Study Arms (2)

Interventional

EXPERIMENTAL

Hospitalizations randomized to receive risk model-driven CDS

Other: Risk model-driven CDS

Standard of Care

NO INTERVENTION

Hospitalizations randomized to receive Standard of Care in a given clinical setting

Interventions

The CDS intervention will use an automated risk model called "VTE-AI" to add EHR-based prompts in the form of alerts targeting those encounters on which 1) VTE-AI risk is above 5% predicted risk (found to be high risk in prior analyses), 2) no active DVT prophylaxis pharmacologic order is present, 3) no contraindication has been documented in the current admission
