‘VTE disease is the new MRSA’, with much attention received in the media and the political world. Following the 2010 NICE guidelines all patients admitted to hospital should have VTE prophylaxis considered and a formal VTE risk assessment done with documentation and review in a 24 hour period. We carried out a completed audit cycle to identify our adherence to these guidelines and introduced a novel method to ensure compliance. An audit of 400 patients admitted to the orthopaedic department was carried out with review of case notes. Three key parameters were investigated: Firstly the compliance of carrying out a risk assessment for VTE disease with correct documentation, secondly investigating how many patients got re-assessed in 24 hours and finally if patients received appropriate VTE prophylaxis. The data was re-audited following the introduction of a new drug chart with a box section for VTE risk assessment and prophylaxis on the chart itself.Introduction
Materials/Methods
We present the 12 month data on the relatively novel drug Dabigatran Etexilate (Pradaxa), a new oral anticoagulant which was introduced to combat the risk of post operative venous-thromboembolic disease (VTED) in orthopaedic surgery. This drug was introduced at our hospital in March 2010 and we present our modified protocol of: using 5000u subcutaneous Dalteparin whilst in hospital and giving Dabigatran only on discharge, and at a lower dose (150mg compared to 220mg). We carried out a retrospective analysis of the notes and imaging of every patient who underwent elective hip and knee arthroplasty over 12 months since the drug was introduced. We evaluated the rate of VTED complications and the rate of transfusion and bleeding post operatively. The case series of 370 patients showed a 1% risk of deep vein thrombosis with no pulmonary emboli and 1 death due to an unrelated cause. There was a transfusion rate of 11% with 0.5% patients taken back to theatre for evacuation of haematomas. There were no reported adverse effects of Dabigatran. We argue that our modified protocol for this novel drug should be followed as it is both safe and effective for postoperative anticoagulation.
At 10 years we have a survivorship, if femoral aseptic loosening is used as an end point, of 97.6%. There was a deep infection rate of 1.2%, and a dislocation rate of 1.9%. There were no cases of thigh pain, and no intra-operative femoral neck/shaft fractures.
