RESUMO
BACKGROUND: There is willingness in Europe to implement the use of a biopsychosocial model such as the International Classification of Functioning, Disability and Health (ICF) for assessing work incapacity. OBJECTIVE: A preliminary study was conducted to investigate the perceptions of medical advisers on the value of structuring clients' biopsychosocial information in an ICF-based report. METHOD: A sample (nâ=â101) received a perception questionnaire after watching two comparative videos based on a clinical case. Questions relating to work incapacity were also asked. The data was analysed using quantitative methods. Comments were also collected. RESULTS: Before knowing the ICF-based report, 61.96% of the respondents believed a return to work seems possible by providing adapted work or a different job. There is an increase of 8.69 pp (p-value: 0.077) after reading the report. Opening up the initial sample to more insurance physicians (nâ=â119), the difference is more significant (p-value: 0.012). Also, 71.9% of respondents believe they have a better view of the client's biopsychosocial situation after reading the report. Respondents recognise the clinical and diagnostic relevance of ICF but say it cannot be used at the moment for various reasons, such as the time required or the need for a multidisciplinary team and effective coordination. Older respondents are less enthusiastic about the appropriateness of using ICF. CONCLUSION: The respondents identify an added value in having a biopsychosocial based-report. After learning about the report, more physicians see opportunities for professional re-integration than before. The medical advisers and their team must be strengthened and receive a clear role in order to empower them.

BACKGROUND: A frame of reference is needed to increase the comparability of vocational rehabilitation assessment instruments and the interpretation of their results. The International Classification of Functioning, Disability and Health (ICF) is a relevant framework, and when linking rules are used, items from existing assessment instruments can be linked to the appropriate categories as described in the ICF. OBJECTIVE: To develop an adapted linking methodology in which experts are involved by means of the application of consensus methods and to transfer this result in a step-by-step set of guidelines, supporting researchers and professionals, linking complex instruments to the ICF. METHODS: The main researcher developed the initial linking of the Integration von Menschen mit Behinderungen in die Arbeitswelt (IMBA) to the ICF by rigorously applying the refined ICF linking rules. To validate this linking, the Delphi and nominal group technique was integrated through different steps, and experts were involved in the process. The method section describes the linking process chronologically with focuses on the used approach, the involvement of experts, and the processing of the output. RESULTS: The results are presented in a 7-step set of guidelines describing the chronological process from the initial to the validated linking. These guidelines describe the core elements in the application of the linking rules and consensus methods in a manual for researchers who are interested in linking complex instruments to the ICF by involving experts. CONCLUSIONS: The Delphi and nominal group technique can be successfully integrated in the linking process, making it possible to involve experts in linking complex instruments to the ICF. A homogeneous composition of the expert panel in terms of knowledge, a heterogeneous composition in terms of setting, a rigorous and repeated application of the linking rules, and structured processing of the output are essential to achieve a valid linking.

OBJECTIVES: This study aimed to (i) investigate actual work participation in Belgian spondyloarthritis (SpA) patients compared with the general population, and (ii) identify determinants of work-related outcomes. MATERIAL AND METHODS: Adult SpA patients from the Ghent University Hospital based Be-GIANT cohort (fulfilling ASAS classification criteria) were cross-sectionally questioned on their socio-economic status and completed a Work Productivity and Activity Impairment questionnaire (May 2018 to May 2019). Results were compared with national and regional data on the general population using indirect standardization. Associations between clinical and job characteristics and work-related outcomes were analysed with logistic regression (having a paid job) and negative binomial hurdle models (sick leave and presenteeism, i.e. restrictions while at work). RESULTS: A total of 215/262 (82%) patients of working age (<65 y/o) had a paid job, corresponding to an age- and sex-adjusted employment ratio of 1.00 (95% CI 0.88, 1.14). Patients worked 39.6h (10.5h)/week, and 49% (95% CI 42, 56%) reported sick leave in the previous year, similar to the general population (39.7h/week, 42%). In total, 56% reported presenteeism of median (IQR) 10% (0-20%). In multivariate analysis, functional impairment (BASFI) and health-related quality of life (HRQoL, EuroQoL-VAS) were associated with each work-related outcome, while contextual factors (education, physically demanding job) were positively associated with, respectively, having a paid job and presenteeism. Clinical characteristics showed no independent association with any of these outcomes. CONCLUSIONS: Evidence from this academic cohort study does not support a work participation gap between SpA patients and the general population, but confirms the role of physical function, overall HRQoL, and education or job type as risk factors for adverse work outcomes.

Implementation and enforcement of COVID-19 control measures are essential to limit the spread of the virus. Unfortunately, these actions are very difficult, if not impossible, for part of the population, mainly present in the socio-economically disadvantaged categories. This difficulty is linked, on the one hand, to the lack of health literacy, which is found to be insufficient among almost a third of the European population, and on the other hand, to their increased exposure to the virus. Difficulty in reading and acquiring health measures therefore leads to a challenge for institutions, a socio-economic gap and impacts on future generations. There is therefore no choice than to invest massively in education and health promotion in the long term to minimize the impact of crises and thus limit the increase in inequalities.

BACKGROUND: This study assessed the psychosocial determinants as explanatory variables for the length of the work disability period. The aim was to estimate the predictive value of a selected set of psychosocial determinants from the Quickscan questionnaire for the length of the sick leave period. A comparison was also made with the most common biomedical determinant: diagnosis. METHODS: In a cohort study of 4 981 insured Belgian patients, the length of the sick leave was calculated using Kaplan-Meier. Predictive psychosocial determinants were selected using backward conditional selection in Cox regression and using concordance index values (C-index) we compared the predictive value of the biomedical to the psychosocial model in a sample subset. RESULTS: Fourteen psychosocial determinants were significantly (p<0.10) related to the length of the sick leave: health perception of the patient, physical workload, social support management, social support colleagues, work-health interference, psychological distress, fear of colleagues' expectations, stressful life-events, autonomy, learning and development opportunities, job satisfaction, workload, work expectations and expectation to return to work. The C-index of this biopsychosocial model including gender, age and labour status was 0.80 (CI: 0.78; 0.81) (n=4 981). In the subset of 2 868 respondents with diagnostic information, the C-index for the same model was .73 (CI: 0.71; 0.76) compared with 0.63 (CI: 0.61; 0.65) for the biomedical model. CONCLUSIONS: A set of 14 psychosocial determinants showed good predictive capacity (C-index: 0.80). Also, in a subset of the sample, the selected determinants performed better compared with diagnostic information to predict long-term sick leave (>6 months).

OBJECTIVES: The number of sick-listed employees has increased dramatically worldwide. Therefore, many countries aim to stimulate early and sustainable return to work opportunities to obtain better health outcomes and lower costs for disability pensions. To effectively orientate resources to patients with a high risk of not resuming work spontaneously, it is necessary to screen patients early in their sickness absence process. In this study, we validate "Quickscan", a new instrument to assess return-to-work needs and to predict risks of long-term sick leave. METHODS: As part of the Quickscan validation process, we tested and compared the reliability and construct validity of the questionnaire in two different populations. First, we conducted a cross-sectional study in which the screening instrument was sent to sick-listed individuals in healthcare insurance. In a second cross-sectional study, sick-listed workers who consulted the occupational health physician for return-to-work assessment were asked to fill out the questionnaire. We compared both samples for descriptive statistics: frequencies, means and standard deviations. Reliability of the scales was calculated using Cronbach's alpha. Confirmatory factor analysis was performed to evaluate the construct (factorial) validity of the studied scales using software package AMOS 24. RESULTS: The screening tool was shown to be an instrument with reliable scales (except for the perfectionism and health perception patient scale) in both populations. The construct validity was satisfactory: we found that the hypothesized measurement models with the theoretical factors fitted the data well in both populations. In the first sample, the model improved for scales concerning stressful life events and showed worse fit for person-related factors. Work-related factors and functioning factors both showed similar fit indices across samples. We found small differences in descriptive statistics, which we could explain by the differences in characteristics of both populations. CONCLUSIONS: We can conclude that the instrument has considerable potential to function as a screening tool for disability management and follow-up of sick-leave, provided that some adaptations and validation tests are executed.

OBJECTIVES: Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) are the leading causes of death in systemic sclerosis (SSc). Although the six-minute walk test (6MWT) is used for evaluating ILD and PAH, no data are available on the evolution of the six-minute walk distance (6MWD) in SSc patients without ILD and PAH and whether the baseline 6MWD could serve as individual reference value for the management of those who will develop PAH or ILD. METHODS: Prospectively collected data of the first 6MWT (at baseline or 6-month follow-up) and the 6MWTs at 18-, 30-, 42-, 54-, and 66-month visit of 165 consecutive SSc patients without ILD and PAH, included in the Ghent University SSc Cohort between May 2006 and December 2016 were analysed. RESULTS: 96-100% of the included patients performed a 6MWT during the follow-up visits. The mean 6MWD during the baseline 6MWT of 165 SSc patients without ILD and PAH (35% limited, 56% limited cutaneous, 9% diffuse cutaneous SSc) was 484.20+/-92.65m with no significant difference in the 6MWD at different follow-up visits as compared to baseline. In 46 SSc patients without ILD and PAH who performed a 6MWT at baseline and at 66-month visit, the 6MWD walked at 66-month visit correlated with the baseline 6MWD (r=0.564, p<0.001). CONCLUSIONS: In SSc without ILD and PAH, the 6MWT is feasible and the 6MWD is clinically stable over a 66 months period. Hence, the individual 6MWD might be used as individual reference value in management of those who will develop PAH or ILD.

BACKGROUND: Disability management (DM) is a systematic method to ensure job-retention and job-reintegration in competitive employment for individuals with a disability. There is evidence that 'returning to work' has a positive impact on the individual, the company and on the society. However, a clear overview of the efficacy and efficiency of the DM programs is scarce. OBJECTIVE: To systematically review the efficacy and efficiency of the disability management programs. Cochrane, PubMed, Google Scholar, and Web of Science were searched from 1994 to 2015. METHODS: Two reviewers independently evaluated the articles on title, abstract, and full text. The data extraction and results are documented according to the study designs. RESULTS: Twenty-eight articles were included in the review. These 28 articles consisted of 7 systematic reviews, 3 randomized controlled trials, 9 clinical trials, 4 mixed-method studies and 5 qualitative studies. CONCLUSIONS: The DM program has shown to be effective and efficient. A consensus about the DM components is still not reached. Nevertheless, some components are emphasized more than others; job accommodation, facilitation of transitional duty, communication between all stakeholders, health care provider advice, early intervention, and acceptance, goodwill and trust in the stakeholders, in the organization, and in the disability management process.

Nailfold capillaroscopy is an easy, non-invasive technique to assess microvascular involvement in rheumatic diseases. Multiple studies describe capillaroscopic changes in systemic lupus erythematosus (SLE), including a wide range of non-specific findings. On behalf of the European League Against Rheumatism (EULAR) study group on microcirculation in rheumatic diseases, a systematic review was done to obtain all original research studies (in English) in which SLE patients had capillaroscopy. Forty such studies are identified. This article firstly provides a résumé of the results of these studies according to capillaroscopic parameters (density, dimensions, morphology, haemorrhages), semi-quantitative assessment and qualitative assessment of capillaroscopy in SLE patients. Secondly, the correlations between capillaroscopic parameters in SLE patients and clinical and laboratory parameters (including auto-immune parameters) are outlined. The following capillaroscopic parameters are found to be significantly more prevalent in SLE patients compared to healthy controls: tortuous capillaries, abnormal morphology and haemorrhages. Hairpin-shaped capillaries are significantly less prevalent than in healthy persons. The semi-quantitatively determined nailfold capillaroscopic score (NFC score) in SLE patients is also higher than in healthy controls. Several correlations between clinical and laboratory parameters and capillaroscopic parameters are identified in the review. Disease activity is correlated with NFC score in seven studies, with abnormal morphology (i.e. "meandering") in one study and with haemorrhages in one study. Frequent attacks of Raynaud's phenomenon (RP) and gangrene are significantly correlated with dilated capillaries. In two studies a possible correlation between anti-SSA antibodies and lower density of capillaries is withheld. About other immune parameters conflicting results are found. In one study a significant negative correlation is found between 24-hour proteinuria and abnormal morphology (i.e. "meandering"). For the first time, an overview of the nailfold capillaroscopic changes that have been described in SLE and their correlations with clinical and laboratory findings is given. Further large-scale research on the identification of capillaroscopic changes in SLE and their correlations with standardised clinical and laboratory parameters, is ongoing at the EULAR study group on microcirculation in rheumatic diseases.

OBJECTIVES: Following results in open-label studies of rituximab in patients with systemic sclerosis, a Belgian three-centre initiative was launched to explore safety and efficacy of rituximab in early, diffuse cutaneous systemic sclerosis (dcSSc). METHODS: Open-label study of 17 patients with early dcSSc, treated with two courses of rituximab, at month 0 and 6. Clinical examination, lung function testing, echocardiography, disease activity score (DAS) and functional status were performed at baseline and over 24 months of follow-up. RESULTS: Modified Rodnan skin score (MRSS) changed significantly over time, with a mean of 25.5 (standard deviation [SD] 6.0) at baseline to 12.6 (SD 5.1) at month 24 (Mixed Model Analysis [MMA] p < 0.0001), which is a decrease of 51% at month 24 vs. baseline. DAS showed significant decrease over the total study period, with a score of 4.1 (SD 1.7) at baseline to 1.5 (SD 1.8) at month 24 (MMA p < 0.0001). Additionally, this was significant at all time points vs. baseline, both for MRSS and DAS. Internal organ status remained clinically stable throughout the study period. No statistically significant differences compared to baseline were found at the follow-up time points. Seven serious adverse events took place, all except for one, considered unrelated to study medication. CONCLUSIONS: This is the first multicentre Belgian collaboration investigating potential efficacy of rituximab in early dcSSc. Rituximab appears to be safe and tolerable and it may have beneficial effects on skin involvement, on overall disease activity and on stabilization of internal organ status in early dcSSc.

Screening for pulmonary arterial hypertension (PAH) in systemic sclerosis (SSc) improves outcomes. The DETECT screening algorithm is recommended in a high-risk SSc subgroup. This study aims to compare prospectively the positive predictive value of screening using the DETECT algorithm and the 2009 European Society of Cardiology/European Respiratory Society (ESC/ERS) guidelines, and to compare their cost-effectiveness in an unselected, day-to-day SSc population. Post hoc, screening according to the 2015 ESC/ERS guidelines using echocardiographic parameters alone ("2015 echo screening") or combined with the DETECT algorithm ("2015 combined screening") in high-risk subjects was analysed.195 consecutive SSc patients included in the Ghent University Hospital SSc cohort were screened using different algorithms.The referral rate for right heart catheterisation was 32% (63 out of 195 patients) (46/4/13/34/40 patients using the DETECT algorithm/2009 guidelines/both/2015 echo screening/2015 combined screening). Right heart catheterisation was performed in 53 patients (84%) (36 (78%)/four (100%)/13 (100%)/28 (82%)/32 (80%) patients recommended by the DETECT algorithm/2009 guidelines/both/2015 echo screening/2015 combined screening). PAH was diagnosed in three patients (incidence 1.5%·year-1, 95% CI 0.5-4.4), in whom all algorithms recommended a right heart catheterisation. The positive predictive value was 6% (95% CI 2-17%; three out of 49 patients) for the DETECT algorithm, 18% (95% CI 6-41%; three out of 17 patients) for the 2009 guidelines, 23% (95% CI 8-50%; three out of 13 patients) for both, 11% (95% CI 4-27%; three out of 28 patients) for the 2015 echo screening and 9% (95% CI 3-24%; three out of 32 patients) for the 2015 combined screening. The cost was EUR224/80/90/112 per patient using the DETECT algorithm/2009 guidelines/2015 echo screening/2015 combined screening.Echocardiography may remain a candidate first step for PAH screening in SSc.

OBJECTIVES: Interstitial lung disease (ILD) and pulmonary arterial hypertension (PAH) are the leading causes of death in systemic sclerosis (SSc) patients. Although the six-minute walk test (6MWT) is used for evaluating ILD and PAH in clinical practice, no data are available on six-minute walk distance (6MWD) and oxygen desaturation in SSc patients without ILD and PAH. METHODS: Prospectively collected data of the 6MWTs at baseline and 6-month follow-up of 300 consecutive SSc patients, included in the Ghent University Hospital Systemic Sclerosis Unit between May 2006 and April 2015 were analysed. RESULTS: The mean 6MWD of 165 SSc patients without ILD and PAH who performed a 6MWT at baseline or at the 6-month visit was 484±93m. Patients in the diffuse cutaneous (DcSSc) subgroup (435±94m) walked less than in the limited (LSSc) subgroup (499±91m, p=0.04) and tended to walk less than in the limited cutaneous (LcSSc) subgroup (483±92m, p=0.15). In 115 SSc patients without ILD and PAH who walked at both moments, there was no significant difference between the 6MWDs (mean difference -7.60m 95%CI [-19.93m; 4.73m], p=0.23) and the oxygen desaturation was not statistically different in 102 of them (mean difference 0.41% 95%CI [-0.49%; 1.31%], p=0.37). CONCLUSIONS: In SSc without ILD and PAH, the 6MWD and oxygen desaturation is clinically stable over a 6 months period. The DcSSc subgroup walks less than the LSSc and the LcSSc subgroup.

OBJECTIVES: Reviewing disease activity indices (DAI) in systemic sclerosis (SSc) and reporting their validation status. METHODS: Literature was systematically reviewed on studies documenting the development of DAI, assessing the validation status of DAI and studies using a DAI in their analysis. The qualitative and quantitative validation status of existing DAI was assessed based on OMERACT and on definitions of the American College of Rheumatology (ACR) committee on quality measures. RESULTS: Three DAI in SSc have been proposed in literature: the European Scleroderma Study Group (EScSG) activity index, the 12-point DAI and the Combined Response Index for Systemic Sclerosis (CRISS). The EScSG activity index is yet applied as an outcome measure in 48 different studies. The EScSG activity index and the CRISS are provisional partially validated DAI. CONCLUSIONS: Future studies are needed to fully validate the EScSG activity index and the CRISS and to assess the validation status of the 12-point DAI.

OBJECTIVES: The European Scleroderma Study Group (EScSG) activity index meets nearly all the OMERACT-standards of truth, discrimination and feasibility. The sensitivity to change remains to be attested. This study assesses sensitivity to change of the EScSG activity index in patients with early and severe diffuse cutaneous Systemic Sclerosis (dcSSc) treated with rituximab. METHODS: 12-month follow-up (open-label study) of 14 consecutive patients with early dcSSc. Patients received an infusion of two times 1000 mg rituximab at month 0 and 6, together with 100 mg methylprednisolone. Clinical read outs (modified Rodnan skin score [mRSS], lung function and echocardiography) and EScSG activity index were performed at month 0, 3, 6 and 12. Mixed models analyses (MMA) were used to evaluate changes in parameters over time. RESULTS: There was a clinically significant change in skin score with a mean (SD) mRSS of 24.8 (4.44) at baseline and 10.4 (3.12) at month 12 (MMA p<0.001). Also the EScSG activity index decreased significantly, with a mean (SD) of 4.3 (1.79) at baseline and 0.7 (0.83) at month 12 (MMA p<0.001). The estimated mean change of the EScSG activity index was -3.6 (95%CI -4.9; -2.4) over 12 months. Indices of internal organ involvement remained stable throughout the study. CONCLUSIONS: A significant improvement of the EScSG activity index was observed, in line with the significant improvement of the mRSS and the stabilisation of internal organ involvement. To our knowledge, this is the first study to attest sensitivity to change of the EScSG activity index in the subset of 'early' dcSSc.

Systemic sclerosis (SSc) is an autoimmune connective tissue disease characterized by vasculopathy and progressive fibrosis of the skin and visceral organs (gastrointestinal tract, heart, kidneys and lungs). Although the prevalence is low, SSc is a disease with high morbidity and mortality. Since pulmonary arterial hypertension (PAH) associated with SSc (SSc-PAH) and clinically evident cardiac involvement is associated with increased mortality, the cardiac complications and PAH in SSc are reviewed. Both diffuse cutaneous (DcSSc) and limited cutaneous (LcSSc) subgroups are at risk for cardiac involvement and SSc-PAH. Cardiac involvement can be divided in pericardial involvement, myocardial involvement and rhythm disturbances and mostly occurs asymptomatically. However, when symptomatic, it is associated with a poor prognosis. Screening for asymptomatic cardiac involvement should be considered in SSc in order to initiate treatment in an early stage. However, there are no randomized controlled trials on treatment options for cardiac involvement in SSc. SSc-PAH is a devastating complication of SSc, which can develop early in DcSSc and LcSSc. Screening for PAH should be performed since screening leads to earlier diagnosis and earlier treatment is associated with a better prognosis. Today, screening is performed by clinical judgement and echocardiography. Recently the DETECT algorithm, a 2-step screening algorithm is proposed in a SSc-subgroup at increased risk for PAH, but further validation is needed. Despite current treatment options with prostacyclins, endothelin-1 receptor antagonists and phosphodiesterase type-5 inhibitors, mortality remains high. Several promising new treatment options for PAH are evaluated in phase II and III clinical trials.

BACKGROUND: Pulmonary arterial hypertension (PAH) and interstitial lung disease (ILD) are the leading causes of death in systemic sclerosis (SSc). Although the six-minute walk test (6MWT) is generally used for evaluating PAH and ILD, utility in SSc is undetermined. This study evaluates the role of 6MWT in SSc by systematic review and meta-analysis. METHODS: A systematic literature search on PubMed, Web of Science and Cochrane Library Online was performed using the medical subject heading search terms for "systemic sclerosis", "CREST" and "six minute walk test", "six minute walk distance (6MWD)", "(cardiopulmonary) exercise test", "treadmill test" or "step test". RESULTS: Meta-analysis of 43 included studies (3185 SSc-all patients) revealed that the mean 6MWD was comparable between the SSc-PAH and SSc-ILD-PH subgroups (288m [95% CI: 259-317m] vs 286m [95% CI: 259-314m], p=0.93). The pooled mean of 725 SSc-PAH patients was significantly lower than the pooled mean of 413 SSc-noPAH patients (430m [95% CI: 402-458m], p<0.001). 95 SSc-ILD-PH patients walked significantly less than 328 SSc-ILD patients (388m [95% CI: 362-415m], p<0.001) and significantly less than 86 SSc-noILD patients (420m [95% CI: 325-515m], p=0.008). 81-98% of the SSc-PAH/ILD/ILD-PH patients performed a 6MWT. CONCLUSIONS: During a 6MWT, SSc-PAH patients walk less than SSc-noPAH patients and SSc-ILD-PH patients walk less than SSc-ILD and SSc-noILD patients.

OBJECTIVE: To propose simple capillaroscopic definitions for interpretation of capillaroscopic morphologies and to assess inter-rater reliability. METHODS: The simple definitions proposed were: normal--hairpin, tortuous or crossing; abnormal--not hairpin, not tortuous and not crossing; not evaluable--whenever rater undecided between normal and abnormal. Based upon an aimed kappa of 0.80 and default prevalences of normal (0.4), abnormal (0.4) and not evaluable (0.2) capillaries, 90 single capillaries were presented to three groups of raters: experienced independent raters, n = 5; attendees of the sixth EULAR capillaroscopy course, n = 34; novices after a 1-h course, n = 11. Inter-rater agreement was assessed by calculation of proportion of agreement and by kappa coefficients. RESULTS: Mean kappa based on 90 capillaries was 0.47 (95% CI: 0.39, 0.54) for expert raters, 0.40 (95% CI: 0.36, 0.44) for attendees and 0.46 (95% CI: 0.41, 0.52) for novices, with overall agreements of 67% (95% CI: 63, 71), 63% (95% CI: 60, 65) and 67% (95% CI: 63, 70), respectively. Comparing only normal vs the combined groups of abnormal and not evaluable capillaries did increase the kappa: 0.51 (95% CI: 0.37 ,: 0.65), 0.53 (95% CI: 0.49, 0.58) and 0.55 (95% CI: 0.49, 0.62). On the condition that the capillaries were classifiable, the mean kappa was 0.62 (95% CI: 0.50, 0.74) for expert raters (n = 65), 0.76 (95% CI: 0.69, 0.83) for attendees (n = 20) and 0.81 (95% CI: 0.74, 0.89) for novices (n = 44). CONCLUSION: This multicentre, international study showed moderate reliability of simple capillaroscopic definitions for describing morphology of capillaries by rheumatologists with varying levels of expertise. Novices were capable of distinguishing normal from abnormal capillaries by means of a 1-h training session. In future studies, the class not evaluable may be obsolete.

OBJECTIVE: Scores on the Health Assessment Questionnaire (HAQ) predict the need for support measures in patients with rheumatoid arthritis (RA). In this study we compare the performance of the HAQ in this context with that of the more disease-specific Belgian Rheumatoid Arthritis Disability Assessment (BRADA) questionnaire. METHODS: In this multicenter observational study, patients with RA and disease duration of at least one year who consulted their rheumatologist for a routine follow-up visit filled out the HAQ, and BRADA questionnaires. The performance of HAQ and BRADA to predict the need for support measures available to patients with RA was evaluated using Receiver Operator Characteristic (ROC) curves, with the expert opinion of the rheumatologist as a reference. RESULTS: The study analyzed data of 301 patients with RA (70.8% females) with mean age 59.8 ± 12.8, disease duration 11.4 ± 9.3 years, and DAS28 values of 2.84 ± 1.18. HAQ scores averaged 0.97 ± 0.73 and BRADA scores were 3.92 ± 3.49 over the last week and 3.89 ± 3.50 over the last 3 months. The area under the ROC curves for the BRADA scores for the support measures investigated ranged from 0.702 to 0.862 and did not differ significantly from those of the HAQ (range 0.725-0.860). CONCLUSION: The disease-specific BRADA questionnaire is equivalent to the HAQ in predicting the need for support measures in patients with stable RA.
