OBJECTIVE: To analyze visual analog scales (VAS) for pain and patient global estimate on a Multidimensional Health Assessment Questionnaire (MDHAQ) in formats other than a traditional 10 cm horizontal line, designed to facilitate scoring on MDHAQ in usual clinical care. METHODS: The MDHAQ with VAS for pain and global estimate was completed by each patient at each visit. VAS formats other than a traditional (unnumbered) 10 cm horizontal line based on 21 circles at 0.5 intervals were analyzed. Formats included unnumbered, symbol at the 11th circle, numbers and/or squares (instead of circles) at selected intermittent scores, and numbers at each circle. Analyses were performed to study the time to score MDHAQ with different VAS formats, possible 'clustering' of responses in any format, particularly with intermittent numbers and/or symbols, and test-retest reliability of various formats. RESULTS: The median time to score MDHAQ with a 10 cm line VAS was 15.6 seconds, compared to 7.4 seconds for the 21 numbered circle VAS. No other format was scored in fewer seconds. Clustering was seen for scores of VAS formats with intermittent numbers or symbols, which rendered them unsuitable for use. No clustering was seen for the 21 numbered circle VAS format, for which test-retest agreement was significant, and similar to the 10 cm line VAS format. CONCLUSION: A 21 numbered circle VAS may be a desirable alternative to a 10 cm horizontal line, yielding similar results and requiring less than half the time to score

OBJECTIVE:To determine the patterns and correlation of elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels with outcome measures in rheumatoid arthritis (RA), and compare it to systemic lupus erythematosus (SLE) and osteoarthritis (OA) patients.METHODS:Brooklyn Outcomes Arthritis Registry Database (BOARD) was analyzed to determine both first visit and mean values of ESR and CRP, along with disease activity measures in each patient. Data were analyzed with descriptive statistics and correlations.RESULTS:Among all patients half of all (n=377) ESR results were elevated. In RA patients the proportions of having both ESR and CRP elevated, both within normal levels, and only one elevated and the other normal were similar. For all diagnosis, both ESR and CRP have weak positive correlations with disease activity measures measured at first visits. ESR and CRP have a modest positive correlation with each other across all three disease groups.CONCLUSION:In this cohort of RA, SLE and OA patients, ESR and CRP values were modestly correlated with each other and they were weakly correlated with disease activity measures. These data suggest that another look at the role of ESR and CRP as markers of inflammation in RA patients seen in routine care may be in order
