Brief Summary

Hospitalized medical patients have an increased risk of venous thromboembolism (VTE) across the continuum of care, including after hospital discharge. In the APEX Trial of hospitalized patients with acute medical illness, extended-duration post-discharge thromboprophylaxis with oral betrixaban reduced the frequency of asymptomatic proximal deep venous thrombosis (DVT), symptomatic proximal or distal DVT, symptomatic nonfatal pulmonary embolism (PE), or VTE-related death compared with short-duration enoxaparin. Obstacles to integration of these data in the hospitalized Medical Service patient population, including failure to identify at-risk patients, educational gaps in strategies for VTE prevention after discharge, and medication nonadherence, can be overcome with alert-based computerized decision support. This study is a single-center, 400-patient, randomized controlled trial of an EPIC Best Practice Advisory (BPA; alert-based computerized decision support tool) to increase prescription of extended-duration post-discharge thromboprophylaxis and decrease symptomatic VTE in high-risk patients hospitalized with medical illness. Specific Aim #1: To determine the impact of electronic alert-based CDS (EPIC Best Practice Advisory \[BPA\]) on prescription of extended-duration post-discharge thromboprophylaxis in high-risk patients hospitalized with medical illness who are not being prescribed any prophylactic anticoagulation for VTE prevention after discharge. Specific Aim #2: To estimate the impact of electronic alert-based CDS (EPIC BPA) on the frequency of symptomatic VTE in high-risk patients hospitalized with medical illness who are not being prescribed any prophylactic anticoagulation for VTE prevention after discharge.

Outcome Measures

Primary Outcomes (1)

  • Frequency of prescription of extended-duration post-discharge thromboprophylaxis.

    Investigators will review the order entry section of the Electronic Health Record (EPIC) to make this determination.

    90 days

Secondary Outcomes (4)

  • Frequency of symptomatic VTE at 90 days from randomization.

    90 days

  • Frequency of major bleeding (as defined by the ISTH bleeding classification system) at 90 days from randomization.

    90 days

  • Frequency of all-cause mortality at 90 days

    90 days

  • Frequency of all-cause rehospitalization at 90 days

    90 days

Other Outcomes (1)

  • Medication adherence

    35 days

Study Arms (2)

Alert

EXPERIMENTAL

On-screen electronic alert that notifies the provider about the increased risk for VTE after discharge and indication for thromboprophylaxis will be issued 48 hours after admission. This first on-screen electronic alert will provide the clinician with the opportunity to consider extended-duration, post-discharge thromboprophylaxis and start any required processes for prior authorization or medication coverage. The provider then will be given on-screen options to either order thromboprophylaxis (betrixaban or low-molecular weight heparin for 35 days) from a "Extended-Duration VTE Prevention" order template, follow a link to evidence-based practice guidelines, or defer prescribing extended-duration, post-discharge thromboprophylaxis.

Behavioral: Electronic alert

No Alert

NO INTERVENTION

No notification to the provider.

Masking Details
Investigators will randomize patients by Attending Physician ID# to minimize the influence of an alert effect on the care of patients not randomized to the alert group but who have the same Attending Physician (thereby reducing what is called the "cluster-effect"). While investigators will randomize patients by Attending Physician of Record to minimize cluster-effect, the observational unit will be the patient.
