There is currently wide variation in the management of patients who are anticoagulated with Warfarin and require urgent orthopaedic surgery. These form an important and significant group of patients, in terms of real numbers (at least 5,600 per annum in the UK). A study was initiated with an audit of 34 patients presenting to the West Wales unit who were warfarinised at admission and required trauma surgery. Observations were recorded about their pre-operative management and the delay this caused in taking the patient to theatre. 6 months later, a similar group of patients were re-audited. The mean delay to surgery in those patients in whom the INR was left to fall spontaneously was 5.5 days. Following administration of 1mg i.v. Vitamin K in those patients without cardiac valves, re-audit showed the mean delay reduced to 2.2 days. Representations from at least 6 major specialties were considered and a consensus statement was derived. Standardised protocols, which hinge on whether or not the patient has or does not have a cardiac valve were devised. Vitamin K should not be given to those patients with a cardiac valve and early consultation with cardiology and anaesthetics is recommended, with consideration of referral to a specialist cardiothoracic unit. For those patients without a cardiac valve, 1mg of Vitamin K may be administered, repeated as necessary until the INR is less than 1.8. Intravenous Heparin should be provided in the interim whilst the patient is waiting for surgery. This is discontinued the morning of surgery and subcutaneous Heparin reinstated post-operatively. These recommendations have been trialled in the two units involved in the study and have been relatively safe and easy to implement

Aims

The ongoing COVID-19 pandemic has disrupted and delayed medical and surgical examinations where attendance is required in person. Our article aims to outline the validity of online assessment, the range of benefits to both candidate and assessor, and the challenges to its implementation. In addition, we propose pragmatic suggestions for its introduction into medical assessment.

This population-based study investigated the incidence and trends in venous thromboembolic disease after total hip and knee arthroplasty over a ten-year period. Death or readmission for venous thromboembolic disease up to two years after surgery for all patients in Scotland was the primary outcome. The incidence of venous thromboembolic disease, including fatal pulmonary embolism, three months after surgery was 2.27% for primary hip arthroplasty and 1.79% for total knee arthroplasty. The incidence of fatal pulmonary embolism within three months was 0.22% for total hip arthroplasty and 0.15% for total knee arthroplasty. The majority of events occurred after hospital discharge, with no apparent trend over the period. The data support current advice that prophylaxis should be continued for at least six weeks following surgery. Despite the increased use of policies for prophylaxis and earlier mobilisation, there has been no change in the incidence of venous thromboembolic disease.
