The objective was to assess the performance of the SF-36 health survey (SF-36) in a sample of patients with rheumatoid arthritis (RA) stratified by functional class. The eight SF-36 subscales and the two summary scales (the physical and mental component scales) were assessed for test retest reliability, construct validity and responsiveness to self-reported change in health. In 233 patients with RA, the SF-36 scales were: reliable (intra-class correlation coefficients 0.76-0.93); correlated with American College of Rheumatology (ACR) core disease activity measures [Spearman r = -0.12 (erythrocyte sedimentation rate) to -0.89 (Modified Health Assessment Questionnaire)]; and responsive to improvements in health (standardized response means 0.27-0.9). The distribution of scores on four of the eight subscales (physical function, role limitations physical, role limitations emotional and social function) was clearly non-Gaussian. Very marked floor effects were noted with the physical func...

Living with a chronic disease affects many aspects of an individual’s life. The aim of this study was to compare the health-related quality of life, as measured by the SF-36, in patients with early rheumatoid arthritis (RA) at disease onset and after 2 years. The results were furthermore compared with those of patients with medium-term disease and a control group. Forty patients with early RA as well as 39 RA patients with 21–25 years of disease duration and 40 controls were asked to answer the self-administered SF-36 health profile measure. Both patients with early RA and with medium-term disease reported significantly lower values for all eight subscales compared with the controls. At follow-up after 2 years, the patients reported significant improvements on the role physical (RP) and bodily pain (BP) dimensions compared with at disease onset. Physical functioning (PF) was perceived as better in patients with early RA compared with patients who had had the disease for 21–25 years. Women reported significantly higher values for some of the scales than men. In summary, health-related quality of life is negatively affected in early RA as measured by the SF-36. An improvement was implicated after 2 years. There were some gender differences in reported health-related quality of life among patients with early RA, but not in patients with medium-term disease.

The questionnaire included the HAQ, which was used to assess functional status. Changes in HAQ scores over 5 years were analyzed.ResultsIn 2000, 73% of 1,495 patients with RA and 77% of 2,000 general population controls responded to the questionnaire. In 2005, 84% of 2,022 patients with RA and 77% of 1,817 controls responded. A total of 863 patients with RA and 1,176 community controls responded in both 2000 and 2005 and were included in the analyses. Mean baseline HAQ scores were significantly higher in patients with RA than in controls (0.71 versus 0.17; P < 0.001). Over 5 years, the HAQ scores increased by 0.01 units per year in both the RA cohort and the community population; in both cohorts, the net change was primarily attributable to individuals over age 70 years. Changes in HAQ scores were similar in patients and controls who had low HAQ scores at baseline. Female patients with baseline HAQ scores of ≥0.5 had less potential for improvement than did controls. Among subjects in both groups who had HAQ scores >2, death was a common outcome over the next 5 years.In 2000, 73% of 1,495 patients with RA and 77% of 2,000 general population controls responded to the questionnaire.

Our results showing stable function scores over 5 years in most patients with RA who are younger than age 70 years provide further evidence of improved status of RA patients today compared with the major declines observed in previous decades.Currently, progression of functional disability among patients with RA and among persons in the general population is largely explained by the aging process.

EVALUATION OF RHEUMATOID ARTHRITIS PATIENTS WITH HEALTH ASSESSMENT QUESTIONNAIRE- DISABILITY INDEX
The Health Assessment Questionnaire-Disability Index (HAQ-DI) is an instrument most commonly and widely used to measure the function in patients with rheumatoid arthritis (RA). HAQ-DI is a component of the two-page HAQ (short form) which was published in 1980 by ARAMIS and serves as a model of patient-oriented outcome. It has been translated in more than 60 languages. It is consisted of 20 questions divided in 8 categories of functioning. The aim of the study is to evaluate the functioning of RA patients at Rheumatology Clinic in Skopje with HAQ-DI. 95 patients with RA have been interviewed by filling in the HAQ-DI questionnaire with the help of their rheumatologist. The average HAQ-DI score in our RA patients at Rheumatology Clinic in Skopje is 1,36+/-0,71, in the range of 0,13-2,75. Patients in the category of 50 to 70 years of age have the highest HAQ-DI scores. Overall, 52 out of 95 RA patients (54,7%) have HAQ-DI scores exceeding 1,25, meaning that they have serious difficulties in their everyday life and activities. In order to maximize the functioning and thus minimize disability, HAQ-DI should be more frequently and constantly used in patients with RA who need to be educated how to administer the questionnaire by themselves.
Determinants of Disability in Rheumatoid Arthritis: A Community-Based Cohort Study
The Open Rheumatology Journal, 2015
Longitudinal care of a community-based cohort of patients with rheumatoid arthritis (RA) was evaluated retrospectively. Candidate determinants of disability included visual analog scales (VAS) for patient global assessment and pain, comorbidities, and medications. The outcome was the ‘patient-acceptable symptom state’ for disability as defined by the Health Assessment Questionnaire (HAQ) disability index, using a cutoff of <1.04. Two-sample t tests and multivariable logistic regression were used to determine odds ratios (OR) for associations between predictor variables and disability. Out of a total of 99 patients, 28 (28%) patients had HAQ ≥1.04 at their last visit. The greatest odds of not attaining the patient-acceptable symptom state in a multivariable model was associated with corticosteroids (OR: 5.1; p=0.02), antidepressants (OR: 5.3; p=0.02), and female sex (OR: 6.5; p=0.05). In the era of biologic therapy, female sex, corticosteroids, and antidepressants remain profound ...
Application of the health assessment questionnaire disability index to various rheumatic diseases
2010
Abstract Purpose To investigate whether the Stanford Health Assessment Questionnaire Disability Index (HAQ-DI) can serve as a generic instrument for measuring disability across different rheumatic diseases and to propose a scoring method based on item response theory (IRT) modeling to support this goal. Methods The HAQ-DI was administered to a cross-sectional sample of patients with confirmed rheumatoid arthritis (n= 619), osteoarthritis (n= 125), or gout (n= 102).
Factors Associated With Disability in Patients With Rheumatoid Arthritis
JCR: Journal of Clinical Rheumatology, 2010
Background: Many patients with rheumatoid arthritis (RA) do not attain remission/low disease activity, remaining in a moderate disease activity state (MDAS) with ongoing disability and impaired quality of life (QoL). If patients in persistent MDAS with poor future outcomes could be prospectively identified, they could arguably be treated more intensively. We evaluated baseline factors predicting function (Health Assessment Questionnaire-Disability Index [HAQ-DI] scores) and QoL (3-level EuroQol-5 dimensions questionnaire [EQ-5D-3L] index scores) at 12 months in patients with RA in persistent MDAS in a real-world setting. Methods: Patients with persistent MDAS (Disease Activity Score for 28-joint count based on erythrocyte sedimentation rate [DAS28-ESR] 3.2-5.1 on at least two consecutive outpatient appointments over 12 months) were identified retrospectively from Guy's Hospital RA Centre and analysed in two groups: (1) biologic naïve at baseline or (2) receiving/ever received biologics. The baseline timepoint was the second-visit MDAS DAS28-ESR score; the endpoint was the closest visit to 12 months. Linear regression analyses evaluated relationships between baseline variables and (1) 12-month HAQ-DI scores, (2) 12-month rank-transformed EQ-5D-3L index scores, (3) 12-month changes in HAQ-DI scores, and (4) 12-month changes in EQ-5D-3L index scores.
