<h3>Background</h3> Rheumatoid arthritis (RA) is a chronic, disease that affects more than 1% of global population, it is a long term condition that causes pain and disability. Evidence had shown that most of the patients are moderately disabled, which brings the necessity of a caregiver to become the patients companion due to its chronic disease. The caregiving role can have an impact in the psychological and physical spheres of the caregivers life. <h3>Objectives</h3> The aim of this study was to explore demographical characteristics and caregiver burden through the Zarit Scale. <h3>Methods</h3> We conducted a cross sectional study in a meeting where caregivers in a rheumatoid arthritis specialized setting. We collected sociodemographic information, and applied the Zarit caregiver burden interview (ZBI) adapted to Spanish. The ZBI includes 22 questions which has 5 responses from 0 (never) to 4 (nearly always), where scores lower than 47 indicated little to no burden, 47 to 55 low burden and >55 intense burden. We calculated means, and standard deviations for continuous variables and categorical variables were presented as rates. <h3>Results</h3> We applied a survey to 132 caregivers. Mean age was 52 years SD 19 and 72% were women, 78% of them were taking care of a patient with rheumatoid arthritis, 12% osteoarthrosis 2% lupus, 2% osteoporosis the remaining 6% were caregivers of patients with ankylosing spondylitis, fibromyalgia, Sjogren syndrome. Regarding the time as caregiver 48% of them had been carrying the task for less than a year, 16% between two and three years, 18% for more than three years, and 13% for more than four years 5% of them were temporarily caregivers. In our study 85% of caregivers were a family member while15% was a nurse or a non-related person. Zarit mean score was 38.2913, additionally 35% had a score higher than 41 points. See table 1. <h3>Conclusion</h3> In our study 93% of our patients reported to have moderate to severe burden; thus, it is important to develop strategies and explore the factors related to burden in caregivers in patient with rheumatoid arthritis. <h3>Disclosure of Interests:</h3> Diana Buitrago-Garcia: None declared, Laura Villarreal: None declared, Michael Cabrera: None declared, Pedro Santos-Moreno Grant/research support from: Dr Santos has received research grants from Janssen, Abbvie and UCB, Speakers bureau: Dr Santos has received speaker fees from Sanofi, Lilly, Bristol, Pfizer, Abbvie, Janssen and UCB, Fernando Rodriguez: None declared
