Comparison of the Risk of Venous Thromboembolism (i.e., Blood Clots in the Veins) and Bleeding Events in a Population of Obese Patients Receiving Higher-Dose or Extended-Duration Versus Conventional-Dose or Conventional-Duration of Prophylaxis (i.e., Preventive Treatment) With Enoxaparin

Comparison of the Risk of Venous Thromboembolism and Bleeding Events in a Population of Obese Patients Receiving Higher-Dose or Extended-Duration Versus Conventional-Dose or Conventional-Duration of Prophylaxis With Enoxaparin

In individuals with obesity, the optimal dosing and duration of venous thromboembolism (VTE) prophylaxis in settings representing acute medical illness or surgery is limited due to lack of randomized controlled trials (RCTs) focusing specifically on this population. Evidence suggests that in obese participants, both higher dosing and duration of VTE prophylaxis with Low Molecular Weight Heparins (LMWH) may be required to achieve a therapeutic effect similar to non-obese participants.

This non-interventional study utilizes data already collected from a usual clinical practice setting in the Optum US clinical database, representing obese participants hospitalized with an acute medical condition or undergoing surgery receiving enoxaparin prophylaxis. Its aim is to compare the impact of the following enoxaparin prophylaxis strategies on the incidence of symptomatic VTE and major bleeding in the overall study population and prespecified subgroups:

  • High versus conventional dose
  • Extended versus conventional duration
  • Combined High-Dose and Extended-Duration versus Conventional-Dose and Conventional-Duration.

The first date of enoxaparin prophylaxis will be the index date.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Conventional prophylaxis
Hospitalized obese participants with an acute medical condition or undergoing surgery, receiving conventional (i.e., 40 mg once daily for 7 days) enoxaparin VTE prophylaxis
High dose prophylaxis
Hospitalized obese participants with an acute medical condition or undergoing surgery, receiving high dose enoxaparin for the conventional VTE prophylaxis duration
Extended duration prophylaxis
Hospitalized obese participants with an acute medical condition or undergoing surgery, receiving the conventional enoxaparin dose for an extended VTE prophylaxis duration

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in the incidence of symptomatic VTE, from index date to Day 90
Time Frame: Retrospective data analysis from February, 2010 to September, 2021, with this endpoint evaluated up to 90 days after the individual participant's index date.
The VTE endpoint is intended to represent a new onset symptomatic VTE event. It will be identified in the proposed database by utilizing an algorithm based on the International Classification of Disease 10th and 9th revisions (ICD-10 and ICD-9) codes.
Retrospective data analysis from February, 2010 to September, 2021, with this endpoint evaluated up to 90 days after the individual participant's index date.
Change in the incidence of major bleeding, from index date to Day 90
Time Frame: Retrospective data analysis from February, 2010 to September, 2021, with this endpoint evaluated up to 90 days after the individual participant's index date.
The major bleeding event will be identified via an algorithm based on the International Classification of Disease-10th revision and 9th revision (ICD-10 and ICD-9) codes.
