Antidepressant drug use and subdural hematoma risk

Journal of Thrombosis and Haemastasis

Study (10,885 subdural hematoma (SDH) cases & 435,379 matched controls) found SSRIs (adjusted OR 1.32 [1.25‐1.38]) and non‐SSRIs (aOR 1.19 [1.13‐1.26]) were associated with higher SDH risk vs. non‐use of antidepressants; but absolute risk is judged to be small.


Different strategies for pharmacological thromboprophylaxis for lower-limb immobilisation after injury: systematic review and economic evaluation

National Institute for Health Research

Meta-analysis (n=6857; 13 trials) found thromboprophylaxis (TP) in this setting is clinically (low-molecular-weight heparin reduced risk any VTE: OR 0.52, 95% CI, 0.37-0.71) and cost (£13,524 per QALY) effective vs. no TP. Estimates of risk of major bleeding were inconclusive.


Hospitalization as an opportunity to correct errors in anticoagulant treatment in patients with atrial fibrillation

British Journal of Clinical Pharmacology

Study (n=4427) found patients with treatment errors (ERs) hospitalised for AF/with stroke history more likely to have such ERs corrected but many ERs are still overlooked. After nontreatment, DOAC underdosing and vitamin K antagonists use instead of DOAC are most common ER types.


NHS Scotland approves reimbursement of Hemlibra (emicizumab) for treatment of patient with severe congenital haemophilia A without factor VIII inhibitors


In trials, Hemlibra dosed once-weekly or every two weeks led to statistically significant reduction in treated bleeds compared to on-demand treatment. In pooled data a high proportion of patients, both with and without inhibitors, achieved zero treated bleeds.
