Abstract
The use of shoulder ultrasound in clinic is a way of decreasing the time patients have to wait til definitive treatment is started. Although ultrasound is used in clinic by some surgeons, we are not aware of anyone specifically looking at the total cost implications and the impact on waiting times.
We therefore prospectively assessed the outcome of a one-stop shoulder assessment service set up by a new Consultant Orthopaedic Surgeon in a busy unit. All new patients were assessed by the Consultant, who then performed an ultrasound if indicated. Treatment or further investigation was then instituted based on the findings. The time taken and accuracy of the scans, the number of patients seen, impact on waiting times, total savings and patient satisfaction were assessed. We based cost calculations from data that included capital, structural, maintenance and staffing costs gained from the Department of Health and the hospital management.
We found that 65% of all shoulder patients required ultrasound, and these were performed in an average of 2.7 minutes, with no significant overrunning of the clinic. The sensitivity for the detection of full thickness rotator cuff tears was 88% and specificity was 89%. Four patients needed further ultrasonography by a specialist musculoskeletal radiologist. All patients reported high satisfaction rates. We calculated the cost saving over a year of two shoulder surgeons performing ultrasound in a similar setting was between £200,000 and £500,000 depending on the figures you used.
We believe ultrasound is a quick, easy, cheap imaging process for the diagnosis of soft tissue shoulder diseases. When performed at the first consultation by the surgeon it offers the advantages of high patient satisfaction rates, shorter waiting times, and significant cost savings. Should all shoulder surgeons be performing ultrasound in clinic?
