Summary

The purpose of this study is to compare aspirin versus low-molecular weight heparin (LMWH) (Enoxaparin) as a thromboprophylaxis in patients who sustain a fracture.

Description

Patients who sustain orthopaedic trauma are at an increased risk of venous thromboembolism (VTE), including fatal pulmonary embolism (PE). Current guidelines recommend low-molecular-weight heparin (LMWH) for VTE prophylaxis in orthopaedic trauma patients. However, emerging literature in total joint arthroplasty patients suggests the potential clinical benefits of VTE prophylaxis with aspirin. This trial aims to determine if aspirin is non-inferior to LMWH for thromboprophylaxis in fracture patients.

Exclusion Criteria

Patients who present to the hospital more than 48 hours post injury
Patients on long term blood thinners (other than low-dose aspirin or platelet inhibitors such as Plavix or Aggrenox)
Patients who received more than 2 doses of LMWH or aspirin for initial VTE prophylaxis
Patients who have had a VTE within the last 6 months
Patients on therapeutic (as opposed to prophylactic) blood thinners for an acute issue at the time of admission
Patients who have a newly diagnosed indication for therapeutic blood thinners (for example vascular injury) that will require therapeutic anticoagulation for more than one week
Patients who cannot receive either of the study medications due to an allergy (history of heparin induced thrombocytopenia, allergy to aspirin, or NSAIDs) or other medical contraindication to blood thinners
Patients who are on higher dose aspirin (>81 mg once a day or higher) for medical reasons or who will be treated with higher dose aspirin
Patients with underlying chronic clotting disorders (i.e. Factor V Leiden, hyperhomocysteinemia, Protein C and S deficiency) that require full dose anticoagulation or are a contraindication to venous thromboembolism chemoprophylaxis
Patients with end stage renal disease or impaired creatinine clearance <30 ml/min at time of randomization(note: creatinine clearance does not need to be documented if prescribing physician would order medication without test as SOC)
Pregnant or lactating patients
Patients contraindicated for any reason for either medicine
Prisoners
Patients who do not speak either English or Spanish
Patients may be excluded for other reasons at the discretion of the treating physician; the reason for exclusion must be documented on the screening form
Patients who have a known COVID-19 diagnosis prior to fracture treatment or within 3 months of the index fracture
