Background Estimates of global status by doctors (DOCGL) and patients (PATGL) are discordant in about 30-40% of patients with rheumatoid arthritis (RA).1,2 This discordance has been analyzed to date only in RA patients.
Objectives To analyze levels of discordance between DOCGL and PATGL in all patients with any diagnosis seen in usual clinical care at a rheumatology setting.
Methods Each patient seen at an academic rheumatology clinical setting since 2005 completes a self-report MDHAQ (multidimensional health assessment questionnaire) at each visit, with scales for physical function, pain, PATGL, fatigue, anxiety, depression and quality of sleep, and demographic data. DOCGL was completed by 2 rheumatologists. One random visit of patients seen between 2005 and 2011 was analyzed, patients were classified as PATGL=DOCGL (PATGL and DOCGL within 2 of 10 units), PATGL>DOCGL (PATGL ≥2 units than DOCGL), and DOCGL≥PATGL (DOCGL ≥2 units than PATGL). Univariate odds ratios were computed to identify variables associated with discordance. Significant variables (p<0.05) were included in multivariate models, with selected variables when indicated.
Results In a total of 980 patients studied, 509 (52%) had PATGL=DOCGL, 371 (38%) PATGL>DOCGL, and 100 (10%) DOCGL>PATGL. Patients with PATGL>DOCGL were more likely to be female, have less formal education and have higher MDHAQ scores (Table). In multivariate analysis, higher pain and fatigue scores were independent predictors of PATGL>DOCGL. If MDHAQ scores for pain and fatigue were not included in a second model, female gender, lower education and higher scores for depression and sleep problems were independent predictors of PATGL>DOCGL. In patients with DOCGL>PATGL, only lower fatigue was associated in multivariate analysis with lower odds of discordance (OR=0.88, 95% CI 0.79-0.98).
Conclusions 38% of patients estimated their statusas worse than their physicians. These patients were more likely to score higher for pain and fatigue, be female and less educated than patients whose physicians estimated clinical status as similar or worse than patients.
