Sat0292 self-Administered Versus Interview Based International Consensus Criteria for the Diagnosis of Raynaud’s Phenomenon Questionnaire – A Single Centre Experience

Abstract

BackgroundInternational Consensus Criteria for diagnosing Raynaud’s Phenomenon (RP) have been proposed recently (1). These criteria are based on the three-step conditional approach (i.e. a screening question, assessment of colour changes and an item of disease score calculation). It is unclear whether differences exist between the self-administered and interview-based way of questionnaire fulfilment.ObjectivesWe aimed in our study to evaluate the two approaches in patients with suspected RP.MethodsThis cross-sectional study was conducted at our secondary/tertiary rheumatology centre between 1 October 2018 and 31 December 2018. Each patient referred for the video capillaroscopy was asked to complete the RP questionnaire on the day of the referral. The same questionnaire was applied as an interview by the rheumatologist before the video capillaroscopy. Differences in answers and level of individual agreement on individual three items, as well as the result of the questionnaire, between the two ways of questionnaire completion were assessed with Fisher exact test and Kappa coefficient, respectively.ResultsDuring the 3-month period we included 84 consecutive patients (88.1% female, median age (IQR) 49.5 (41.9–56.5) years). Results of answers to each item, final outcome of the questionnaire and the level of individual agreement for each item are presented in Table 1.Table 1 Answers to Raynaud’s phenomenon International Consensus Criteria questionnaire according to mode of administrationSelf-administeredInterview basedp-value**Measure of individual agreement– Kappa coefficient (95% CI)Yes, N (%)Yes, N (%)Item 1.

However, we observed that the patients were inclined to score the severity of their RP lower than the physicians.Reference[1] Maverakis E, Patel F, Kronenberg DG, Chung L, Fiorentino D, Allanore Y, et al.
