Warfarin and epistaxis--a case controlled study.

Patients anticoagulated with warfarin form a small proportion of those admitted with epistaxis annually to ENT units. The authors formed the impression that such patients spend longer in hospital and have more complicated management than controls. A prospective age and sex matched controlled study of 20 consecutive patients admitted with epistaxis whilst anticoagulated was performed. This showed that these patients spent significantly longer in hospital than controls, with an additional expense in the study period of 10,500 pounds for inpatient bed nights alone. The management of these patients is more complicated and there is a subgroup of poorly controlled patients who present most of the problems. A potential solution is to improve community warfarin control and to involve general practitioners and haematologists in the re-establishment of warfarin following admission for epistaxis.
