  1. Audit of patients on oral anticoagulants with International normalized ratios of eight or above.

    Article - En anglais

    We reviewed retrospectively the medical records of all patients (n=77. mean age 74.2) on oral anticoagulants with an International normalized ratio (INR) of eight or above in a 12-month period in the Leicestershire District Health Authority (DHA).

    From a total of 55 625 INRs, 131 (0.24%) were = 8. A major cause of over-anticoagulation was unsatisfactory dose loading during in-hospital commencement of oral anticoagulation.

    The incidence of major bleeding was 1 2.9% of total episodes of INR = 8 X with two haemorrhage-related fatalities.

    Therapy of major haemorrhage with fresh frozen plasma (FFP) and intravenous (i.v.) vitamin K proved effective but was not given in a majority of such cases.

    In conclusion, improvements in initial dose loading of oral anticoagulation and in the management of major haemorrhage are required, Severely over-anticoagulated patients without obvious bleeding should nevertheless receive small dose vitamin K therapy to reduce the risk of haemorrhage related morbidity and mortality without compromising subsequent oral anticoagulant control.
