853 The Use of 3d-Printed Wrist Models to Aid Patient Understanding of Diagnosis and Treatment

Abstract

Abstract Aim Models of the wrist allow for complex anatomy to be visualised and explained, aiding clinician to patient discussion. This pilot study aimed to investigate in impact on patient understanding of their diagnosis and treatment using a 3D-printed model hand in consultation. Method 3D-printed model wrists based on dissection specimens done in Anatomy, University of Edinburgh, were created to demonstrate a variety of pathologies, including triangular fibrocartilage tears and scapholunate ligament injuries. Patients participated by questionnaire at hand clinic appointment with responses recorded on a visual analogue scale (VAS) for criteria including confidence explaining their condition to others, and satisfaction before and after use of the models. Results 48 patients participated in the study with 38 questionnaires fully completed. Median age was 44 years old; the right hand was affected more than the left (17 vs. 15) and bilateral in 6 patients. Use of the models saw a significant improvement in patient confidence to explain their condition to a family member (mean change 2.46, range -3 to 8.5; p<0.001), although a wide range of responses were recorded demonstrating individual differences and preferences. Patient satisfaction was excellent (mean 9.25) when the models were used, and a positive net promoter score (mean 9.29) showing patients would recommend the consultation style. Conclusions This pilot study suggests that 3D-printed wrist models aid in patient education at consultation, building patient confidence and maintaining satisfaction. Given the range of responses and individual nature of learning it is likely these models will complement radiological images in this setting.
