An observational study in DVT - Deep Vein Thrombosis and VTE (Venous Thromboembolism), sponsored by Al-Nahrain University. Recruiting at 1 site in Iraq. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-17.
Sponsored by Al-Nahrain University · Observational
The goal of this observational study is to assess the predictive accuracy of the Padua Prediction Score (PPS) for venous thromboembolism (VTE) risk in thoracic surgery patients.
The study aims to answer the following question:
Does the PPS provide a more accurate prediction of VTE risk?
Participants will:
Have their VTE risk assessed using the PPS during their hospital admission.
Venous thromboembolism (VTE) is a significant cause of morbidity and mortality, comprising conditions like deep vein thrombosis (DVT) and pulmonary embolism (PE). Hospitalized patients are particularly vulnerable to VTE due to factors such as prolonged immobility, surgical procedures, and preexisting comorbidities.
To address this risk, tools like the Padua Prediction Score (PPS) have been developed. PPS is a validated scoring system that uses clinical and demographic criteria to categorize patients as high- or low-risk for VTE, allowing healthcare providers to tailor prophylactic measures accordingly. Although the Padua Prediction Score has been increasingly adopted in various healthcare settings, its applicability in Iraq remains understudied. There is limited local data on the prevalence of VTE, risk assessment practices and adherence to prophylaxis protocols, leaving a clear gap in the literature. This study aims to explore the utility and predictive accuracy of the Padua Prediction Score in the Iraqi healthcare context. By addressing this gap, the findings could help refine VTE prevention strategies, improve resource allocation, and ultimately reduce complications associated with this condition.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Incidence of Venous Thromboembolism (VTE) Episodes in Patients
symptomatic or asymptomatic, confirmed by instrumental diagnostics.
Time frame: In-Hospital Phase (average of 10 days through discharge); Post-Discharge Follow-Up: Day 7, Day 15, and Day 30
Padua Prediction Score
A total score that ranges from 0 to 20. 4 or higher indicates a significant likelihood of developing VTE.
Time frame: Day 1 preoperative (one day prior to surgery)
Incidence of Symptomatic Pulmonary Embolism in Patients
symptomatic pulmonary embolism confirmed by perfusion isotope scanning or CT pulmonary angiography.
Time frame: In-Hospital Phase (average of 10 days through discharge); Post-Discharge Follow-Up: Day 7, Day 15, and Day 30
Rate of Recurrent Deep Vein Thrombosis (DVT) in Patients
A new episode of deep vein thrombosis occurs after the initial diagnosis with clinical symptoms (such as leg pain, swelling, redness, or tenderness) and is confirmed through instrumental diagnostics (e.g., ultrasound, CT venography, MRI).
Time frame: Post-Discharge Follow-Up: Day 7, Day 15, and Day 30
