Abstract

Abstract: Objective: We conducted a questionnaire survey within a standard clinical setting to clarify that picture superiority effect (PSE) could be obtained by musculoskeletal ultrasound (MSKUS) examination. Methods: One hundred patients with rheumatoid arthritis or arthralgia, who visited the Rheumatology Unit, Department of Internal Medicine and Rheumatology, Juntendo University Faculty of Medicine, and received first-time MSKUS from June 2017 to August 2017, were sequentially requested to complete an anonymous questionnaire based on their experiences of the explanation with or without MSKUS. MSKUS was implemented as point-of-care ultrasonography (POCUS) or on the other reserved examination day. Results: We obtained answers from all patients ( n = 100); 80% or more subjects strongly agreed that the explanation complemented with MSKUS contributed to 'easier understanding, ' 'better communication, ' and 'preference for MSKUS-available hospital' ( p < .001). This agreement was also observed in elderly patients and when MSKUS was implemented as POCUS. There was no correlation between the number of examined joints ( r = 0.18, p = .15), time required for MSKUS ( r = −0.17, p = .09), the severity of the MSKUS results ( r = −0.06, p = .52), and degree of agreement. Conclusion: MSKUS addition has shown to offer PSE, which contributes to patients' understanding and experience of improved communication. We should acknowledge the effects of PSE by MSKUS and utilize it for informed consent and shared decision-making in musculoskeletal symptomatic patients.
