This study will be a multicenter clustered randomized trial of patients in hospitals in which a universal "SMART on FHIR" platform-based EHR-embedded IMPROVE DD VTE clinical prediction rules (CPRs) with electronic order entry has been incorporated into required admission and discharge EHR workflow versus hospitals following UMC for VTE risk assessment of medically ill patients. The patient population will consist of hospitalized, medically ill (non-surgical, non-obstetrical) individuals aged > 60 years.


Investigators, plan to do a study using a pragmatic, randomized design as part of a Quality Improvement (QI) project as a substudy within the existing NIH R18 proposal of creating a universal "SMART on FHIR" platform of the IMPROVE VTE CPR for key Northwell Health hospitals. Investigators, aim is to assess whether an EHR-embedded CPR for VTE prevention - the IMPROVE VTE CPR - ultimately tied to electronic order entry will increase the proportion of hospitalized medical patients at risk of VTE who receive appropriate thromboprophylaxis, both at hospital admission AND at hospital discharge, compared to UMC. Investigators, secondary aims are to assess whether key adverse outcomes such as symptomatic VTE and hospital readmission for VTE are reduced and whether health -resource utilization metrics are improved.
