The Attitudes and Practices of Physicians Caring for Patients with Rheumatoid Arthritis-Interstitial Lung Disease: An International Survey.

Overview

abstract

OBJECTIVES: This study sought to determine the level of understanding and opinion amongst rheumatologist and pulmonologists regarding risk factors, diagnostic approach and treatment of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). METHODS: We conducted an international electronic survey of rheumatologists and pulmonologists utilizing two separate Redcap-based surveys with questions on the epidemiology, workup and management of RA-ILD as well as ILD screening questions using case-based scenarios directed at rheumatologists. The survey also collected demographic data on participants including their practice setting, years in practice and country of practice. RESULTS: We received a total of 616 responses (354 rheumatologists and 262 pulmonologists) from 6 continents. There were significant differences in responses between pulmonologists and rheumatologists in estimated prevalence and mortality, risk factors for the development of ILD in RA and medications that are effective or should be avoided. Rheumatologists were much less likely to consider assessment for ILD in high risk, asymptomatic patients compared with high-risk patients with either symptoms or exam findings suggestive of ILD. CONCLUSION: Our study brought to light the variability in disease assessment and clinical practice amongst providers caring for patients with RA-ILD and indicate that greater education is needed to optimize clinical decision making in the risk assessment, screening and treatment of RA-ILD. Research questions that address appropriate screening and treatment strategies for RA-ILD will be valuable for rheumatologists given their central role in the overall health and lung health of patients with RA.
