NCT04574895

Brief Summary

The study will evaluate the effectiveness of a novel, real-time risk prediction model for identifying pediatric patients at risk for developing in-hospital blood clots (or venous thromboembolism \[VTE\]) based on data easily extracted from the electronic medical record. The study will assess whether using the risk percentages for developing VTE derived from the model increases the number of high-risk patients screened by the pediatric hematology team, which may may lead to an overall reduction in the number of pediatric VTEs seen at Monroe Carell Jr. Children's Hospital at Vanderbilt.

Outcome Measures

Primary Outcomes (1)

  • Number of VTE Events

    Number of VTE events per hospital admission encounter, per study arm. A VTE event will be defined as an acute venous thromboembolic event (e.g. deep vein thrombosis, pulmonary embolism, etc).

    1 year

Secondary Outcomes (4)

  • Total Number of Patients Started on Anticoagulation

    1 year

  • Total Number of High-Risk Patients Started on Anticoagulation

    1 year

  • Total Number of Patients Started On Anticoagulation If It Was Recommended

    1 year

  • Total Number of Bleeding Events

    1 year

Study Arms (2)

VTE risk prediction scores

OTHER

Patients in the intervention arm will have their VTE risk prediction scores presented to the study team daily on weekdays via an automated report, which will list patients in descending order of risk severity for review by the VTE research team each weekday. Starting with the highest risk patients, the VTE research team will review each patient and clinical situation, and then the VTE research team will directly discuss risks/benefits of prophylactic anticoagulation with the admitting team. Patients with a risk score \<2.5% will not be reviewed, and the investigators anticipate most of the intervention arm patients will fall into this category (based on our previous data, the investigators anticipate \>90% of all patients will score \<2.5%). The VTE risk report will be re-calculated based on updated EHR data every day at midnight.

Other: Hematology Review

Standard of care

NO INTERVENTION

Patients randomized to the control arm will continue to receive current standard of care anticoagulation practice, which is at the discretion of the admitting team. In general, nearly no pediatric patients are offered prophylactic anticoagulation unless a previous VTE has been identified. This currently is at the discretion of the provider and no risk scoring is used. VTE risk prediction scores will be calculated and stored for analysis, these will not be visible to the study team in real time.

Interventions

VTE study team will review VTE risk percentages provided via automated report daily on weekdays and approach the primary team directly if the patient is appropriate for clinical antithrombotic interventions.
