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 VTE; 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. These GRADE- based recommendations offer one of the first evidence-based practice guidelines for thromboprophylaxis decisions in psychiatric in-patient settings.
