MI-összefoglaló
A vizsgálat saját részvételi feltételeiből. Gép olvasta ki az oldalon álló regiszterszövegből, ezért tévedhet. Hogy ki vehet részt, azt a lenti regiszterszöveg és a vizsgálat csapata dönti el.
The trial is looking for adults in the emergency department who are being tested by an emergency doctor for a blood clot in the lungs (pulmonary embolism, PE). It checks a new decision tool called Adjust-Unlikely.
- Életkor
- 18 years and older
- Nem
- All sexes
- A betegség stádiuma
- Suspected pulmonary embolism, being tested for it during an emergency visit
- Korábbi kezelés
- People cannot join if they started treatment for a presumed PE before PE testing. They also cannot join if they had PE or leg clot imaging (CT pulmonary angiogram, ventilation-perfusion scan or lower limb ultrasound) within the prior 30 days.
- Biomarker vagy leletérték
- A D-dimer blood test must be done and have a result during the emergency visit.
A részvétel fő kizáró okai
- A new reason (not PE) to take blood thinners
- Past leg vein clot with no earlier ultrasound scan on record
- Transferred from another hospital
- Not living in Ontario or no valid Ontario Health Insurance Plan card
- Leaving against medical advice, or opted out of all research at the site

A vizsgálatról
Mit akar kideríteni a vizsgálat
It is important to diagnose pulmonary embolism in a timely manner to prevent death and long-term disability. More than half a million people (4-5% of emergency department patients) are tested for pulmonary embolism, although the positive rate is low. Imaging for PE testing exposes patients to radiation, is expensive, adds time to the emergency visit, and can lead to a false positive diagnoses. Existing protocols aimed at reducing unnecessary pulmonary embolism imaging are complex and seldom used by emergency physicians. Too many patients undergo unnecessary pulmonary embolism imaging.
A teljes eredeti leírásKevesebb
A new tool (called Adjust-Unlikely) could safely reduce pulmonary embolism imaging in Canada. A research group composed of researchers, emergency physicians, and patients developed the Adjust-Unlikely clinical decision rule: a rule which has been customized for emergency physicians and emergency patients. Adjust-Unlikely is highly sensitive at the bedside, meaning there are very few false negative results.
The study aim is to prospectively validate Adjust-Unlikely pulmonary embolism testing in emergency patients with suspected pulmonary embolism.
A vizsgálat csoportja
- Emergency department patients tested for pulmonary embolism.
Kezelés: Adjust-Unlikely
