E086 Comparing ankylosing spondylitis disease activity during the COVID-19 pandemic using patient-reported outcome measures with face-to-face clinical evaluation of disease scores pre-pandemic

Abstract Background/Aims During the COVID-19 pandemic, asynchronous consultations were introduced for patients with ankylosing spondylitis (AS). To assess disease activity in the absence of face-to-face clinical review and blood testing, patients submitted patient-reported outcome measures (PROMs) via electronic survey forms which were subsequently triaged by clinicians. We compared pre-pandemic clinician-reported scores with intra-pandemic self-reported scores and assessed clinical outcomes including allocation of follow-up and further management/treatment escalation. Methods Clinician-reported scores were obtained in-person pre-pandemic (defined as 01/01/2019-01/03/2020). Self-reported BASDAI scores were submitted by patients via electronic forms sent out during-pandemic (defined as 01/12/2020-31/03/22). The responses were stored and analysed in a secure database. These scores are analogous to disease activity scores completed by clinicians during outpatient appointments. Score comparison was performed using Wilcoxon Sign Rank testing. We used the need for a follow-up within 3 months as target for those with severe disease. Data analysis was performed in Microsoft Excel and R (version 4.2.1). Results We noted a significantly higher overall level of patient-reported disease activity during the pandemic. In the total cohort of AS patients, the median BASDAI Score collected during-pandemic increased from 5.30 (n = 124, range 0-10) compared to 2.80 pre-pandemic (n = 590, range 0-12) (p 4) increased from 36% pre- to 65% during pandemic. In a smaller cohort of 34 patients for whom we had both pre- and during-pandemic scores, all patient parameters worsened during the pandemic. Notably, median BASDAI increased from 2.65 to 5.62 (p 4). In a focussed sample, 91% of pat
