Summary
Shared decision-making (SDM) tools improve patient care quality in vascular surgery. This trial evaluates decision aids and training to enhance SDM during consultations for conditions like abdominal aortic aneurysms.
Area of Science:
- Vascular Surgery
- Health Services Research
- Patient-Centered Care
Background:
- Shared decision-making (SDM) is crucial for quality patient care but is underutilized in vascular surgery.
- Decision support tools have been developed to facilitate SDM between vascular surgeons and patients.
Purpose of the Study:
- To evaluate the effectiveness and implementation of decision support tools in improving SDM during vascular surgical consultations.
- To assess the impact of these tools on treatment decisions for abdominal aortic aneurysm, carotid artery disease, intermittent claudication, and varicose veins.
Main Methods:
- A multicentre stepped-wedge cluster-randomised trial involving 502 vascular surgical patients.
- Intervention group received decision aids (websites), consultation cards, and practical training to promote SDM.
- The 5-item OPTION instrument was used to score audio-recordings of consultations to measure improvement in SDM.
Main Results:
- The OVIDIUS trial implemented decision support tools in clinical practice.
- The study aimed to achieve a clinically relevant improvement of 10 points in SDM scores.
- The stepped-wedge design ensured all centers implemented tools by study's end.
Conclusions:
- The OVIDIUS trial assessed the real-world implementation and effectiveness of decision support tools in vascular surgery.
- The study design facilitates widespread adoption of SDM principles across participating centers.

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

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...

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...

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...

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and...

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
