Despite increasing scientific investigation, the best method for preventing postoperative thromboembolism in patients undergoing a total hip replacement (THR) remains unclear. National Institute for Health and Clinical Excellence (NICE) and Scottish Intercollegiate Guidelines Network (SIGN) guidelines on the prevention of thromboembolism have caused much controversy. We surveyed Scottish surgeons regarding their thromboprophylaxis prescribing after THR. Questionnaires were sent to all Scottish orthopaedic consultants. They were asked about routine pharmacological and mechanical prophylaxis in patients undergoing a THR. Comparison was made with a previous survey done in 2003. The response rate was 75%. The survey showed an increased use of pharmacological prophylaxis from 93% to 100%. This was due to the increased use of aspirin from 51% to 64%. The use of low molecular weight heparin has remained constant at 51%. No surgeons routinely use warfarin, un-fractionated heparin or fondaparinux. Use of graded compression stockings has increased from 59% to 70%. In conclusion, there is increasing evidence that patients undergoing THR should receive extended prophylaxis for up to 35 days. Oral agents such as dabigatran and rivaroxaban have offered a new option for oral extended prescribing. The results in change of practice must be closely audited.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Pre-Procedural Guidelines for Assessing Blood Pressure

Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.
