E010 Impact of rheumatologist ultrasound clinic on the management of inflammatory arthritis at a tertiary centre rheumatology department

Abstract Background/Aims Musculoskeletal ultrasound plays an important role in the assessment and management of inflammatory arthritis, enabling early diagnosis and prompt initiation of disease modifying therapy, as well as escalation of therapy as part of a treat-to-target strategy. It can help clinicians distinguish between true joint inflammation and non-inflammatory causes of increased pain scores. We reviewed our weekly rheumatology ultrasound clinic service where patients are referred to aid in clinical decision making. The study aimed to evaluate the cohort of patients attending the rheumatology ultrasound clinic at University Hospitals of Leicester, a busy tertiary centre, serving a multi-ethnic population, and to assess the impact of this clinic on the management of inflammatory arthritis in these patients. Methods Data was collected retrospectively from the ultrasound clinic at University Hospitals of Leicester between June 2022 and June 2023. Outcome measures included: date of scan request, date of scan, underlying disease, C - reactive protein (CRP), anti-CCP level, presence of radiographic erosions, presence of active synovitis or erosions on ultrasound, other rheumatologic disease and how the ultrasound findings changed the patient’s management. Results The total number of patients attending the clinic during the study period was 91. Of these, 70% were female and 30% male. Over the study period, 11.8% of patients did not attend their appointment. At the time of referral, 68% of patients had a CRP5, 91% had a negative anti-CCP and 83% had no radiographic erosions. Following the scan, 13% of the patients had active synovitis, and 10% received at least one steroid injection. Interestingly, 86% had no active inflammation and no indication to escalate their disease modifying drug. In our patient cohort, 16% had pre-existing fibromyalgia. In all appointments, the clinician performing the scan showed the ultrasound images to the patient and explained the findings. Conclusion This ultrasound clinic is a key part of the treat-to-target strategy for inflammatory arthritis, enabling escalation of disease modifying therapy where indicated. It allows ultrasound guided and marked injections to be given when needed and identifies patients with non-inflammatory causes of increased pain scores, preventing patients from receiving unnecessary immunosuppression.
