Electronic Strategies to Enhance Venous Thromboemboli (VTE) Prophylaxis in Hospitalized Medical Patients
A study testing Electronic Order Entry System + CDSS and Electronic Order Entry System Only in people with Venous Thromboembolism, run by McMaster University at 3 sites in Canada.
Trial summary
Venous thromboemboli (VTE) are abnormal blood clots that commonly form in the blood vessels of the legs or lungs. They can block normal blood flow, damage organs, and even cause death. The risk of VTE is increased in people who are sick or immobile. Read more about this study

About this study
Official title: Electronic Strategies to Enhance Venous Thromboprophylaxis in Hospitalized Medical Patients
Venous thromboemboli (VTE) are abnormal blood clots that commonly form in the blood vessels of the legs or lungs. They can block normal blood flow, damage organs, and even cause death. The risk of VTE is increased in people who are sick or immobile. VTE is the most common preventable cause of death in hospitalized patients, and its VTE prevention should be a top patient safety priority. Though there is good evidence that injectable blood thinners and/or compression stockings can prevent VTE, over 30% of hospitalized medical patients in Hamilton, Ontario receive inappropriate prevention. Hamilton Health Sciences Corporation is in the process of introducing "electronic order sets" - computer programs that help doctors order medications and other healthcare interventions for their patients. The investigators would like to study if these electronic order sets can help improve the rate of appropriate VTE prevention in hospitalized medical patients. The investigators will examine the rate before and after the introduction of electronic order sets at the Juravinski Hospital and the Hamilton General Hospital. Doctors at the Hamilton General Hospital will also get to use an additional computer program, called a computerized decision support system (CDSS), that helps them decide on the best strategy to prevent VTE in individual patients. The rates of VTE prevention at each hospital will be compared to each other, and to the rates at St. Joseph's Healthcare Hamilton, which will receive neither the order sets nor the CDSS.

What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of hospitalized medical patients who are appropriately managed for VTE prophylaxis
'Appropriate management' is defined as: (i) appropriate non-receipt of any form of prophylaxis when the patient has no VTE risk factors; (ii) appropriate receipt of pharmacologic prophylaxis when VTE risk factors are present and the patient has no contraindications for pharmacologic prophylaxis; or (iii) appropriate receipt of mechanical prophylaxis, when VTE risk factors are present and the patient has contraindications for pharmacologic prophylaxis.
Measured: Participants will be followed for the duration of their hospital stay on a medical ward, an expected average of 5 days
Secondary outcomes (2)
Hospital-acquired venous thromboembolism
VTE is defined as the presence of DVT or PE objectively confirmed by at least one of compression ultrasonography, venography, ventilation-perfusion lung scanning, CT pulmonary angiography, or a conventional pulmonary arteriogram.
'Hospital-acquired' VTE is that which is not clinically evident or suspected at the time of admission, but is diagnosed during or up to 30 days after hospital admission.
Measured: Participants will be followed for 30 days, from the date of hospital admission
Major bleeding
Major bleeding is defined using the International Society of Haemostasis and Thrombosis criteria.
Measured: Participants will be followed for 30 days, from the date of hospital admission

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Venous thromboemboli (VTE) are abnormal blood clots that commonly form in the blood vessels of the legs or lungs. They can block normal blood flow, damage organs, and even cause death. The risk of VTE is increased in people who are sick or immobile. VTE is the most common preventable cause of death in hospitalized patients, and its VTE prevention should be a top patient safety priority. Though there is good evidence that injectable blood thinners and/or compression stockings can prevent VTE, over 30% of hospitalized medical patients in Hamilton, Ontario receive inappropriate prevention. Hamilton Health Sciences Corporation is in the process of introducing "electronic order sets" - computer programs that help doctors order medications and other healthcare interventions for their patients. The investigators would like to study if these electronic order sets can help improve the rate of appropriate VTE prevention in hospitalized medical patients. The investigators will examine the rate before and after the introduction of electronic order sets at the Juravinski Hospital and the Hamilton General Hospital. Doctors at the Hamilton General Hospital will also get to use an additional computer program, called a computerized decision support system (CDSS), that helps them decide on the best strategy to prevent VTE in individual patients. The rates of VTE prevention at each hospital will be compared to each other, and to the rates at St. Joseph's Healthcare Hamilton, which will receive neither the order sets nor the CDSS.

Where is the study taking place?
The record lists 3 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of hospitalized medical patients who are appropriately managed for VTE prophylaxis (time frame: Participants will be followed for the duration of their hospital stay on a medical ward, an expected average of 5 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01401725, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2015; AzTrials last refreshed its copy on 8 Nov 2026.
