Shoulder assessment by smartphone: a valid alternative for times of social distancing

Background: The delivery of orthopaedic care via telemedicine services has the potential to promote accessibility and decrease medical care expenses, while facilitating the control of infectious disease spreading. The purpose of this study was to assess agreement regarding diagnosis, recommended course of management and the perceived need for additional diagnostic testing between a video examination (VE) and a face to face (FTF) assessment of patients with shoulder disorders. Methods: Forty-seven (18 females) patients presenting to a shoulder surgery clinic were assessed consecutively by VE and a FTF examination. All assessments were conducted by a shoulder specialist. Agreement regarding the established diagnosis, the recommended course of management and the need for additional diagnostic tests was assessed using percent agreement and kappa (95% CI) coefficient. Differences in the content, duration and satisfaction between the two examination modes were also assessed. Results: Percent agreement and kappa (95% CI) coefficient for agreement regarding diagnosis were 85.1% and 0.82 (0.69–0.94), respectively. Percent agreement and kappa (95% CI) coefficient regarding the recommended course of management and the need for additional diagnostic testing were 61.7% and 0.43 (0.22–0.63), and 74.5% and 0.49 (0.25–0.74), respectively. The VE resulted in collection of less physical examination information, took longer to complete and was associated with less satisfaction by both patient and examiner. Conclusions: Video examination of patients with shoulder disorders may present a valid alternative to FTF examination. Nevertheless, the content of the video-based physical examination may need to be modified to facilitate a clearer detection of indications for specific interventions or diagnostic tests.
