Objective: To examine the current attitudes towards the prevention of venous thromboembolism among a cohort of surgeons. Design: A postal survey, comprising a questionnaire covering various aspects of venous thromboembolism prophylaxis was sent to all (n=84) consultant general surgeons in Wales. Results: Replies were received from 57 surgeons (68%), all of whom routinely used prophylaxis, the most frequent modalities used being heparin (100%) and graded compression stockings (79%). A combination of physical and pharmacological methods was used by over 89% of surgeons, with 60% starting prophylaxis more than two hours before operation. All surgeons continued prophylaxis after surgery, 53% until patients were mobile, 45% until they were discharged, and one surgeon continued prophylaxis for seven days after discharge. The thrombosis risk factors considered most important by surgeons when deciding about prophylaxis were (i) a previous history of venous thromboembolism, (ii) hypercoagulability, and (iii) malignancy. Conclusions: This study confirms that Welsh surgeons conform to standard methods, but also highlights some uncertainties that are present in current surgical practice. Those who responded all routinely used prophylaxis, the timing of which was variable. The main risk factors identified when considering prophylaxis were previous history of deep vein thrombosis/pulmonary embolism, hypercoagulability, and the presence of malignancy. Suggestions for future practice are made. P ostoperative venous thromboembolism represents a serious threat to patients undergoing a surgical procedure. Without antithrombotic prophylaxis, up to 15% of patients after major abdominal surgery develop a deep vein thrombosis (DVT), with the risk of fatal pulmonary embolism approaching 1%.
Hospital-acquired venous thromboembolism (VTE) accounts for an estimated 25 000 preventable deaths per annum in the UK and is associated with significant healthcare costs. The National Institute for Health and Care Excellence guidelines on the prevention of VTE in hospitalised patients highlight the clinical and cost-effectiveness of VTE prevention strategies. A multidisciplinary quality improvement team (MD QIT) based in a district general hospital sought to improve compliance with VTE prophylaxis prescription to greater than 85% of patients within a 3-month time frame. Quality improvement methodology was adopted over three cycles of the project. Interventions included the introduction of a ‘VTE sticker’ to prompt risk assessment; educational material for medical staff and allied healthcare professionals; and patient information raising the awareness of the importance of VTE prophylaxis. Implementation of these measures resulted in significant and sustained improvements in rates of risk assessment within 24 hours of admission to hospital from 51% compliance to 94% compliance after cycle 2 of the project. Improvements were also observed in medication dose adjustment for the patient weight from 69% to 100% compliance. Dose adjustments for renal function showed similar trends with compliance with guidelines improving from 80% to 100%. These results were then replicated in a different clinical environment. In conclusion, this project exemplifies the benefits of MD QITs in terms of producing sustainable and replicable improvements in clinical practice and in relation to meeting approved standards of care for VTE risk assessment and prescription. It has been demonstrated that the use of educational material in combination with a standardised risk assessment tool, the ‘VTE sticker’, significantly improved clinical practice in the context of a general medical environment.
Junior doctors are commonly asked to prescribe simple medications for symptom relief for patients out of hours. Unfortunately, time constraints and other pressures may lead to delays before the medications are prescribed. A quality improvement project was conducted at a large university teaching hospital to establish the extent of the problem, with the aim of finding measures to improve preemptive prescribing for patients. Baseline data was gathered over three busy wards to calculate the total of new prescriptions made over the course of a weekend. There were 24 new prescriptions required over the weekend, a percentage increase of 14.9% compared to the existing prescriptions on a Friday. Following the first intervention this decreased to 10.2%, and by the second intervention the rate was 4.9%. Data collected several months later confirmed that the interventions remained successful, and preemptive prescribing continued. Overall, our interventions have shown that the number of new prescriptions required out of hours can be reduced by educating junior doctors on preemptive prescribing.
