 1Patients. We performed a retrospective audit from our database for patients who had presented to our fast response team (FRT) with clinical symptoms of lower limb DVT. The FRT is a nurse led outpatient clinic where patients with suspected DVT are referred by general practitioners, Accident and Emergency and Outpatients. Patients have a clinical history, Wells score, D-dimer, and risk factors as well as CUS/DUS (Doppler ultrasound) results documented in a database. The initial audit period was March 2009 to March 2010 and a reaudit on our implemented changes and patient management algorithm was performed from September 2011 to February 2012. A total of 816 patients' **data** were evaluated. Out of these, 526 patients were referred between March 2009 and March 2010 and 290 patients were referred from September 2011 to February 2012.
