P602 Changes in emotional health and work-related outcomes in patients with moderate to severe ulcerative colitis 1 year after diagnosis: Results from the MOSAIK cohort in Korea

Abstract Background As the treatment paradigm of inflammatory bowel disease changes towards patient-centred treatment, it is becoming increasingly important to measure patient-reported outcomes (PROs). We aimed to identify the changes of emotional health and work- or activity-related outcomes one year after the diagnosis of ulcerative colitis (UC) and its predictors in patients enrolled in the moderate-to-severe UC in Korea (MOSAIK) cohort (ClinicalTrials.gov: NCT02229344). Methods The MOSAIK cohort is the first nationwide, prospective, inception cohort on moderate-to-severe UC in Korea. Between August 2014 and March 2017, consecutive patients from 30 tertiary hospitals were enrolled. PRO data including hospital anxiety and depression scale (HADS) for emotional health, and work productivity and activity impairment (WPAI) questionnaire for work- or activity-related outcomes, were collected within the first 4 weeks of diagnosis via patient surveys. Wilcoxon-signed rank tests and linear mixed-effects regression models were used for paired comparisons between baseline and 1 year and assessing the predictors of HADS and WPAI. Results Of the 368 enrolled patients, 333 eligible patients were analyzed. The mean age at diagnosis was 39 years and 57.7% (192/333) were male. A considerable number of patients had moderate to high (≥11 by HADS) levels of anxiety and depression (16.0% and 20.5%, respectively), and about half of patients had work and activity impairment (45.5% and 45.8%%, respectively) at baseline. After 1 year follow-up, significant reduction of anxiety and depression (mean difference [MD] in HADS score -1.3 for both anxiety and depression, P<0.001), as well as work and activity impairment (MD -24.1% and -22.4%, P<0.001) was noted. Higher disease activity (partial Mayo Score) during a one-year period was a significant predictor of anxiety, depression, work and social activity impairment. Among the symptoms of UC, abdominal pain was a significant predictor of depression and work and activity impairment, and weight loss and diarrhoea were significant predictors of activity impairment. Conclusion Newly diagnosed moderate-to-severe UC patients had considerable anxiety, depression, and work and activity impairment at baseline, but significant improvement was noted after 1 year. Controlling symptoms and disease activity was the most important factor to improve PROs after 1 year.
