FRI0037 ALL-CAUSE MORTALITY IN EARLY RHEUMATOID ARTHRITIS PREDICTED BY HEALTH ASSESSMENT QUESTIONNAIRE AT ONE YEAR. (2nd June 2020) - Fatima, S.
Abstract : Background: Patients with RA are at greater risk of mortality than the general population. Higher HAQ disability has been associated with hospitalizations and mortality in established RA; whether HAQ disability predicts mortality in early RA (ERA) is unknown. Objectives: The objective of this study is to analyze how well the HAQ can predict future mortality in patients with early RA. Methods: Data were from adult early RA patients (symptoms <1 year) enrolled in the Canadian Early Arthritis Cohort (CATCH) between 2007 and 2017; who initiated treatment with 1 or more DMARDs and had completed HAQ data at baseline and 1 year. Descriptive statistics, t-tests and chi-square tests were used to summarize and compare baseline patient characteristics including sociodemographic variables, RA characteristics and comorbidities amongst deceased and non-deceased patients. Discrete-time proportional hazards models were used to estimate crude and multi-adjusted associations between HAQ at baseline and 1 year, respectively, with all-cause mortality in each year of follow up. Results: This study included 1724 patients with early RA; mean age was 55 years and 72% were female. In 10 years of follow up, 62 deaths (2.4%) occurred. Deceased patients had higher HAQ scores and DAS28 scores at baseline and at 1 year versus the non-deceased group. Age, male sex, lower education, smoking, more comorbidities, higher baseline disease activity and steroid use were associated with mortality in unadjusted survival models (Table 1 ). Contrary to HAQ at baseline, the association between all-cause mortality and HAQ at 1 year remained significant even after adjusting for age, gender, comorbidities, disease activity, smoking, education, seropositivity, symptom duration and steroid use in adjusted survival models (Table 2 ). Conclusion: Higher HAQ at 1 year was significantly associated with all-cause mortality in a large early RA cohort suggesting that poorer disease control and function in the first year of RA contributes to higher mortality.
