A critical appraisal of chronic venous insufficiency ultrasound guidelines—Views of Australian sonographers

Duplex ultrasound is the first line of investigation for patients seeking treatment for varicose veins disease. In Australia, chronic venous insufficiency ultrasound examinations (CVI‐US) are primarily performed by sonographers. The use of clinical guidelines facilitates the practice of ultrasound, and more importantly, provides an assurance to the integrity and quality of the examinations. Our aim is to assess the quality of currently available guidelines and provide recommendations for choosing the appropriate guideline to use and suggestions for future guideline development.
