Utilisation and safety of low molecular weight heparins: prospective observational study in medical inpatients.

Aims: Low molecular weight heparins (LMWHs) are widely used as curative or preventive treatments of thromboembolic diseases. The aim of our study was to: (i) investigate the pattern of prescription of LMWHs in different departments of French teaching hospitals; and (ii) estimate the incidence of adverse drug reactions (ADRs) induced by LMWHs and associated risk factors for the occurrence of bleeding events.
