AbstractThis study provides insight in behavior and perspective of rheumatic patients during the first COVID-19 wave. Especially, we analyzed the patients’ fear of COVID-19 and unauthorized change of immunosuppressive medication in consequence of their fear. We hereby provide data from 877 patients with valuable insights into the patients’ point of view. We retrospectively interviewed patients of our rheumatic university outpatient clinic. This way, we collected information about the patients’ personal point of view. Data like the rheumatic diagnosis and immunosuppressive medication was extracted from the health records. Statistical analysis was conducted using IBM® SPSS® Statistics (version 26). A total of 877 patients were included into our study. We could show that fear of COVID-19 was clearly present in rheumatic patients. Higher fear levels seem to be associated with comorbidity burden. Unauthorized change of immunosuppressive medication was rare in our study (5%). In our study we provide novel insight into patients’ point of view and behavior of rheumatic patients. Unauthorized change of immunosuppressive medication was rare (5%) as seen in other studies. The low rate of unauthorized change and high rate of compliance is reassuring since good disease control appears to be prognostically important in the progression of COVID-19 disease. Therefore, as the pandemic continues, treatment decisions should be made in close consultation between patient and practitioner to improve adherence and reduce morbidity and mortality.
