Interventions for implementation of thromboprophylaxis in hospitalized patients at risk for venous thromboembolism

Cochrane Database of Systematic Reviews

Review of 13 RCTs (n=35,997) found increased prescription of prophylaxis associated with alerts and multifaceted interventions, and increased prescription of appropriate prophylaxis linked to alerts. Analysis was underpowered to assess effect on mortality and safety outcomes.

 

Uterotonic agents for preventing postpartum haemorrhage: a network meta‐analysis

Cochrane Database of Systematic Reviews

Analysis of 140 RCTs (n=88,947) found ergometrine (EG) + oxytocin (OX) combination, carbetocin, and misoprostol + OX were more effective for preventing postpartum haemorrhage (PPH) ≥500 mL than current standard OX. EG +OX was more effective for preventing PPH ≥1000 mL than OX.

 

Haemostatic therapies for acute spontaneous intracerebral haemorrhage

Cochrane Database of Systematic Reviews

Review of 12 RCTs (n=1732) was unable to draw firm conclusions about efficacy and safety of antifibrinolytic drugs for acute spontaneous intracerebral haemorrhage (ICH), and clotting factors vs. fresh frozen plasma for acute spontaneous ICH associated with anticoagulant drug use.

JAMA Neurology

Review of 5 RCTS (n=39,398) found 15 to 20mg dose of rivaroxaban (RV) once daily is linked to increased risks of intracranial haemorrhage vs. aspirin (2 trials; OR, 3.31; 95% CI, 1.42-7.72), while smaller daily doses of RV and apixaban were not, suggesting dose dependent risk.
