AbstractWarfarin is increasingly prescribed in the elderly population for a number of medical conditions. Pre-tibial haematomas are a common cause of morbidity in this group. The aim of the study was to identify the proficiency of INR monitoring at a primary care level in correlation with their recommended INR range and to study the treatment outcome in this group. A retrospective single-centre study of patients diagnosed with pre-tibial haematomas was conducted over a two-year period. Length of hospital stay, time delay until operative intervention, blood transfusion and warfarin reversal requirements, social care input and cost to the NHS were considered. A total of 62 patients were admitted with pre-tibial haematomas of which 20 were on Warfarin. Females were predominantly more affected (5.6:1). The mechanism of injury was as a result of minor trauma. The mean INR level was 3.8 with a standard deviation of 3.1. Mean length of hospital stay was 11 days with a standard deviation of 13.6. Nine patients required skin grafting. Average cost for the acute episode was £3500 per patient. INR levels were significantly outwith the target range causing substantial patient morbidity and imposing a significant financial burden on the NHS. Tighter regulation at a primary care level should help reduce this risk.Copyright © 2012 Elsevier Ltd. All rights reserved.
