Venous thromboembolism prophylaxis in adults hospitalised for psychiatric illness: an evidence-based clinical practice guideline developed using GRADE.

Clinicians should not use parenteral pharmacological prophylaxis in adults hospitalised with psychiatric illness at low risk of venous thromboembolism; and should consider using parenteral pharmacological prophylaxis for high-risk adults with no contraindications.

Graduated compression stockings are not recommended in high-risk patients when parenteral pharmacological prophylaxis is contraindicated.
