RESUMO

BACKGROUND: Disease-modifying anti-rheumatic drugs (DMARDs) are the cornerstone of rheumatoid arthritis (RA) treatment. However, the full benefits of DMARDs are often not realized because many patients are sub-optimally adherent to their medication. In order to optimize adherence, it is essential that healthcare professionals (HCPs) understand patients' barriers and facilitators for medication use. Insight in these barriers and facilitators may foster the dialogue about adequate medication use between HCPs and patients. What HCPs perceive as barriers and facilitators has, so far, scarcely been investigated. This study aimed to identify the perceptions of HCPs on patients' barriers and facilitators that might influence their adherence. METHODS: This qualitative study was performed using semi structured in-depth interviews with HCPs. An interview guide was used, based on an adjusted version of the Theoretical Domains Framework (TDF). Thematic analysis was conducted to identify factors that influence barriers and facilitators to DMARD use according to HCPs. RESULTS: Fifteen HCPs (5 rheumatologists, 5 nurses and 5 pharmacists) were interviewed. They mentioned a variety of factors that, according to their perceptions, influence DMARD adherence in patients with RA. Besides therapy-related factors, such as (onset of) medication effectiveness and side-effects, most variation was found within patient-related factors and reflected patients' beliefs, ways of coping, and (self-management) skills toward medication and their condition. In addition, factors related to the condition (e.g., level of disease activity), healthcare team and system (e.g., trust in HCP), and social and economic context (e.g. support, work shifts) were reported. CONCLUSIONS: This study provided insights in HCPs' perceptions of the barriers and facilitators to DMARD use patients with RA. Most factors that were mentioned were patient-related and potentially modifiable. When physicians understand patients' perceptions on medication use, adherence to DMARDs can probably be optimized in patients with RA leading to more effectiveness of treatment outcomes.

RESUMO

INTRODUCTION: Facilitators and barriers of adherence to disease-modifying anti-rheumatic drugs (DMARDs) have been identified by patients with inflammatory arthritis earlier. However, the relative importance from the patients' perspective of these factors is unknown. Knowledge on this ranking might guide the development of interventions and may facilitate targeted communication on adherence. This study aims to examine 1) the relative importance patients attach to facilitators and barriers for DMARDs adherence, and 2) the relationship between patient characteristics and ranking of these factors. METHODS: One hundred twenty-eight outpatients with inflammatory arthritis; (60% female, mean age 62 years (SD = 12), median disease duration 15 years, IQR (7, 23) participated in a Maximum Difference scaling exercise and ranked 35 items based upon previously identified facilitators and barriers to medication adherence. Hierarchical Bayes estimation was used to compute mean Rescaled Probability Scores (RPS; 0-100) (i.e. relative importance score). Kendall's coefficient of concordance was used to examine a possible association between patients' characteristics (i.e. age, sex and educational level) and ranking of the items. RESULTS: The three most important items ranked by patients were: Reduction of symptoms formulated as "Arthritis medications help to reduce my symptoms" (RPS = 7.30, CI 7.17-7.44), maintaining independence formulated as "I can maintain my independence as much as possible" (RPS = 6.76, CI 6.54-6.97) and Shared decision making formulated as "I can decide -together with my physician- about my arthritis medications" (RPS = 6.48, CI 6.24-6.72). No associations between patient characteristics and ranking of factors were found. CONCLUSIONS: Reducing symptoms, maintaining independency and shared decision making are patients' most important factors for DMARDs adherence. This knowledge might guide the development of interventions and may facilitate communication between health professionals and their patients on medication adherence.

RESUMO

OBJECTIVES: Outcomes obtained using different physical function patient reported outcome measures (PROMs) are difficult to compare. To facilitate standardization of physical function outcome measurement and reporting we developed an item response theory (IRT) based standardized physical function score metric for ten commonly used physical function PROMs. METHODS: Data of a total of 16,386 respondents from representative cohorts of patients with rheumatic diseases as well as the Dutch general population were used to map the items of ten commonly used physical function PROMs on a continuous latent physical function variable. The resulting IRT based common metric was cross-validated in an independent dataset of 243 patients with gout, osteoarthritis or polymyalgia in which four of the linked PROMs were administered. RESULTS: Our analyses supported that all 97 items of the ten included PROMs relate to a single underlying physical function variable and that responses to each item could be described by the generalized partial credit IRT model. In the cross-validation analyses we found congruent mean scores for four different PROMs when the IRT based scoring procedures were used. CONCLUSIONS: We showed that the standardized physical function score metric developed in this study can be used to facilitate standardized reporting of physical function outcomes for ten commonly used make physical function PROMs.

RESUMO

PURPOSE: Nonsteroidal anti-inflammatory drugs (NSAIDs) and acetylsalicylic acid (ASA) are often prescribed concurrently in patients with nociceptive pain and cardiovascular comorbidity. NSAIDs and ASA inhibit the same COX-enzymes, and thus may interact. ASA's cardioprotective antiplatelet effect is entirely COX-1 dependent. NSAIDs can be either non-COX-1 and COX-2 selective or COX-2 selective. The aim of this study was to examine the interaction between ASA and different selective and nonselective NSAIDs on thrombocyte function. METHODS: Single-blind, prospective, placebo-controlled, ex vivo, serial crossover trial of 3-day cycles separated by washout periods of at least 12 days in 30 healthy volunteers, evaluating interaction on ASA's antithrombocyte effect by naproxen, ibuprofen, meloxicam, or etoricoxib taken 2 h before ASA. Ex vivo thrombocyte function, closure time (CT) in seconds, was measured using the Platelet Function Analyzer 100 (PFA-100). CT prolongation during a cycle reflects thrombocyte inhibitory effect. ASA nonresponse was defined as CT prolongation <40 % in the placebo cycle. ASA nonresponders were excluded. Wilcoxon signed-rank was used to evaluate NSAID effect on ASA-induced CT prolongation. RESULTS: Ibuprofen and naproxen inhibit ASA's antithrombocyte effect below the nonresponse threshold. Etoricoxib and meloxicam do not cause relevant change in ASA thrombocyte inhibition. Naproxen has an inherent weak thrombocyte inhibitory action below the ASA response threshold. CONCLUSIONS: COX-1 affinity determines the interaction between NSAIDs and ASA on thrombocyte adhesion and aggregation. Ibuprofen and naproxen, but not etoricoxib or meloxicam, taken 2 h before ASA, significantly inhibit ASA's antithrombocyte effect.

RESUMO

The treatment of choice of H. pylori infections is a 7-day triple-therapy with a proton pump inhibitor (PPI) plus amoxicillin and either clarithromycin or metronidazole, depending on local antibiotic resistance rates. The data on efficacy of eradication therapy in a group of rheumatology patients on long-term NSAID therapy are reported here. This study was part of a nationwide, multicenter RCT that took place in 2000-2002 in the Netherlands. Patients who tested positive for H. pylori IgG antibodies were included and randomly assigned to either eradication PPI-triple therapy or placebo. After completion, follow-up at 3 months was done by endoscopy and biopsies were sent for culture and histology. In the eradication group 13% (20/152, 95% CI 9-20%) and in the placebo group 79% (123/155, 95% CI 72-85%) of the patients were H. pylori positive by histology or culture. H. pylori was successfully eradicated in 91% of the patients who were fully compliant to therapy, compared to 50% of those who were not (difference of 41%; 95% CI 18-63%). Resistance percentages found in isolates of the placebo group were: 4% to clarithromycin, 19% to metronidazole, 1% to amoxicillin and 2% to tetracycline.

RESUMO

The clinical relevance of the concept of bioavailability rests on two main principles. First, that measurement of the active component at the site of action is generally not possible and, secondly, that a relationship exists between on the one hand efficacy and/or safety and on the other hand concentration of the active compound or its active metabolite(s) in the systemic circulation. Applying these principles to the current knowledge on methotrexate (MTX), it is clear that bioavailability of MTX is an important parameter for optimal dosing. In this manuscript the current knowledge on MTX bioavailability is reviewed. This review reveals that bioavailability of MTX in higher oral doses is decreased, most probably by limitation of absorption from the gastro-intestinal tract. It is suggested that higher doses can be given either by splitting the oral dose or by parenteral administration. Both will result in improved bioavailability as compared with one higher oral dose. However, larger, prospective studies directly comparing the efficacy and safety of the splitted oral dose strategy and the switch to parenteral MTX are needed.

RESUMO

OBJECTIVES: To investigate the efficacy and tolerability of allopurinol as the first-choice antihyperuricaemic treatment for gout, and compare the efficacy and tolerability of benzbromarone and probenecid as second-choice treatment. METHODS: Prospective, multicentre, open-label, two-stage randomised controlled trial in gout patients with normal renal function. Enrolled patients were given 300 mg allopurinol for 2 months (stage 1). Those patients who could not tolerate allopurinol or who did not attain the target serum urate concentration (sUr) < or=0.30 mmol/l (5.0 mg/dl), which was defined as successful, were randomised to benzbromarone 200 mg/day or probenecid 2 g/day for another 2 months (stage 2). RESULTS: 96 patients were enrolled in stage 1. 82 patients (85%) were eligible for the analysis at the end of stage 1: there was a mean (SD) decrease in sUr concentration of 35 (11)% from baseline; 20 patients (24%) attained target sUr < or=0.30 mmol/l; and 9 patients (11%) stopped allopurinol because of adverse drug reactions. 62 patients were enrolled in stage 2. 27 patients received benzbromarone (3 patients not eligible for analysis) and 35 received probenecid (4 patients not eligible for analysis). Treatment with benzbromarone was successful in 22/24 patients (92%) and with probenecid in 20/31 patients (65%) (p = 0.03 compared with benzbromarone). Compared with baseline values, there was a mean (SD) decrease of sUr concentration of 64 (9)% with benzbromarone and 50 (7)% with probenecid (p<0.001). CONCLUSION: This study showed that allopurinol 300 mg/day has a poor efficacy and tolerability profile when used to attain a biochemical predefined target level of sUr < or =0.30 mmol/l, following 2 months of treatment. In stage 2, benzbromarone 200 mg/day was more effective and better tolerated than probenecid 2 g/day.

RESUMO

OBJECTIVES: To compare the efficacy and tolerability of allopurinol 300-600 mg/day versus benzbromarone 100-200 mg/day used to attain a target serum urate concentration (sUr) < or =0.30 mmol/l (5 mg/dl). METHODS: A randomised, controlled, open-label, multicentre trial in gout patients with renal function defined as a calculated creatinine clearance > or =50 ml/min. Patients were treated with 300 mg allopurinol or 100 mg benzbromarone once a day (stage 1). If sUr < or =0.30 mmol/l was not attained after 2 months, the dose was doubled to allopurinol 300 mg twice a day or benzbromarone 200 mg once a day (stage 2). The primary end point was treatment success in either of the two stages, defined as clinical tolerability and attainment of biochemical target sUr. RESULTS: Sixty-five patients were enrolled in stage 1; 36 received allopurinol and 29 received benzbromarone. Fifty-five patients (85%) were analysed at stage 1: the success rates were 8/31 (26%) and 13/25 (52%), respectively, and the difference was -0.26 (95% CI from -0.486 to -0.005), p = 0.049. At stage 2, the success rates were 21/27 (78%) and 18/23 (78%), respectively, and the difference was -0.005 (95% CI from -0.223 to 0.220), p = 1.00. Two patients stopped receiving allopurinol and three stopped receiving benzbromarone because of adverse drug reactions. CONCLUSIONS: Increasing the allopurinol dose from 300 to 600 mg/day and the benzbromarone dose from 100 to 200 mg/day according to the target sUr produced significantly higher success rates (both 78% successful in attaining sUr < or =0.30 mmol/l). No significant differences in treatment success between benzbromarone and allopurinol were found after dose escalation. TRIAL REGISTRATION NUMBER: ISRCTN49563848).

RESUMO

OBJECTIVE: To investigate the influence of age on the effectiveness and tolerance of antitumour necrosis factor alpha (TNFalpha) therapy in rheumatoid arthritis (RA). METHODS: 730 patients of the Dutch Rheumatoid Arthritis Monitoring (DREAM) register were categorised into three groups according to their age at initiation of anti-TNFalpha therapy (<45, 45-65 and >65 years). Effectiveness of anti-TNFalpha therapy was primarily assessed by longitudinal analysis of the DAS28 during the first 12 months of treatment. RESULTS: Improvement in disease activity and physical functioning was significantly less in elderly patients, correcting for relevant confounders. Elderly patients reached the EULAR categories of good responders and remission less often than younger patients. Drug survival, co-medication use and tolerance were comparable between the three age groups. CONCLUSION: Anti-TNFalpha therapy significantly reduced disease activity in all age groups of patients; however, it appeared less effective in elderly compared with younger RA patients.

RESUMO

OBJECTIVE: To study the adherence of rheumatologists to the Dutch guidelines for anti-tumour necrosis factor alpha (TNF-alpha) treatment. The secondary objective was to evaluate alternatives to the present guidelines with regard to the percentage of responders and costs. METHODS: The response (>1.2 DAS28 decrease) in patients who started on anti-TNF-alpha treatment for the first time was evaluated at 3 and 6 months after initiation. How many patients continued or discontinued their initial anti-TNF-alpha treatment was evaluated. Possible alternative guidelines were evaluated by means of a decision tree, with regard to the expected percentage of successfully (responders) and unsuccessfully treated patients and expected costs. RESULTS: At 3 months 56% (N = 306) and 44% (N = 233) of all 539 evaluable patients were classified as responders or non-responders, respectively. Despite the guidelines, most (81%) (N = 189) of the non-responders continued treatment. 37% of the non-responders who continued anti-TNF-alpha treatment were eventually classified as responders at 6 months. Decision analytical modelling showed that with equal expected costs all alternative strategies would result in more responders than according to theoretical full adherence with the guidelines. "Continuation in case of partial response" had the best trade-off between successfully treated patients (64%) and unsuccessfully treated patients (17%). CONCLUSION: There was suboptimal adherence to the Dutch guidelines for treatment with anti-TNF-alpha for rheumatoid arthritis patients. This seemed to be justified by the fact that a delayed response up to 6 months was shown. If treatment is continued despite a non-response at 3 months, this is only recommended in patients with at least a partial response (at least 0.6 DAS28 improvement).

RESUMO

OBJECTIVE: To assess, quantify and summarise the cost of illness of rheumatoid arthritis (RA) and ankylosing spondylitis (AS) from the societal perspective. METHODS: Original studies reporting costs of RA or AS were searched systematically. Both cost-of-illness studies and economic evaluations of therapies were included. Studies were appraised for patient and study characteristics, type of costs and actual costs. Reported costs were aggregated by cost categories and overall mean costs were summarised by cost domain (healthcare, patient and family, and productivity costs). RESULTS: Overall mean costs of RA (euro14,906 per year) were above that of AS (euro9,374 per year), while the relative distribution of costs over cost domains was approximately similar. For both diseases, productivity costs based on the human cost approach were 3 to 10 times higher than the friction costs and accounted for more than half the total costs of both diseases. CONCLUSION: Productivity costs constitute the largest part of the total cost-off-illness of RA and AS reflecting the high burden of the disease on work participation. Although total and direct costs of illness in RA were higher than in AS, the average age of AS patients was 10 years lower and therefore, lifetime costs associated with AS may actually be equal or higher.

RESUMO

OBJECTIVE: Although much has been expected of the empowering effect of taking part in online patient support groups, there is no direct evidence thus far for the effects of participation on patient empowerment. Hence our exploring to what extent patients feel empowered by their participation in online support groups, and which processes that occur in these groups are related to the empowering outcomes. METHODS: An online questionnaire was completed by 528 individuals who were active in online groups for patients with breast cancer, fibromyalgia and arthritis. RESULTS: The respondents felt empowered in several ways by their participation. The empowering outcomes that were experienced to the strongest degree were 'being better informed' and 'enhanced social well-being'. No significant differences in empowering outcomes between diagnostic groups were found. The empowering outcomes could only be predicted in a modest way by the processes that took place in the online support groups. CONCLUSION: This study indicates that participation in online support groups can make a valuable contribution to the empowerment of patients. PRACTICE IMPLICATIONS: Health care providers should acquaint their patients with the existence of online support groups and with the benefits that participation in these groups can offer.

RESUMO

Lowering serum urate levels below the threshold for crystal formation with urate-lowering therapy (ULT) has been associated with a lower risk for gout flare reoccurrences. However, gout patients on ULT still commonly suffer from recurring gout flares. The purpose of this study was to explore prognostic factors associated with gout flare recurrence within the first 3 months, in gout patients starting ULT during an acute gout flare. Post-hoc analysis of trial data on acute gout patients randomized to either gout flare standard of care or anakinra treatment were used, including baseline demographic, laboratory, clinical, and patient-reported variables, as well as 3-month follow-up data on gout flare recurrences. Only patients starting ULT at baseline were included. Using variable selection based on clinical relevance, univariate, and multivariate binary logistic regression analyses were done to examine predictors of gout flare reoccurrence. A total of 75 patients were included in this study, of which 36 (48%) experienced a gout flare ≤ 3 months post baseline. The multivariate regression analysis revealed that CRP levels > 30 mg/L (OR 9.47) and lack of prophylaxis when starting ULT (OR 11.56) were independently associated with gout flare recurrence. Similar results were found for the univariate regression analyses. Our results show that CRP levels > 30 mg/L and lack of prophylaxis when starting ULT were prognostic factors for early gout flare reoccurrence in patients starting ULT during an acute gout flare. KEY POINTS: • Gout flare recurrences were common within the first 3 months after starting urate-lowering therapy in gout patients. • Intake of prophylaxis when starting ULT had a strong protective effect on gout flare recurrences. • C-reactive protein level > 30 mg/L was an additional prognostic factor for early (≤ 3 months) gout flare reoccurrence in patients starting ULT during an acute gout flare.

RESUMO

OBJECTIVES: To examine the psychometric properties of the self-administered Dutch Rheumatoid Arthritis Disease Activity Index (RADAI) and its short form (RADAI-SF) in patients with rheumatoid arthritis starting anti-tumour necrosis factor treatment. METHOD: Internal consistency was assessed with Cronbach's alpha. A confirmatory factor analysis (CFA) was carried out to test the single-factor structure. Construct validity was examined by correlating RADAI and RADAI-SF scores with Disease Activity Score in 28 joints (DAS28). Internal responsiveness was evaluated with the paired t test and the standardised response mean (SRM). External responsiveness was assessed with receiver operating characteristic analysis and the SRM, using the EULAR response criterion as external criterion. Change scores were correlated with changes in DAS28. RESULTS: At baseline and after 3 months' treatment, respectively, 191 and 171 patients completed the RADAI. The internal consistency of the RADAI and the RADAI-SF was satisfactory. CFAs confirmed the single-factor structure of both RADAI versions, but the short form provided the best model fit. Moderate correlations were found with the DAS28. SRMs of the RADAI and the RADAI-SF were, respectively, 0.76 and 0.80. Both versions had moderate accuracy to distinguish responders from non-responders. Changes scores were moderately correlated with DAS28 change scores. CONCLUSIONS: This study showed satisfactory psychometric properties of the Dutch version of the RADAI. Omission of the tender joint count (RADAI-SF) produced comparable results and is justified for research purposes. The tender joint count might be useful as additional clinical information in patient management.

RESUMO

AIM: to evaluate the effects of adalimumab, etanercept and infliximab on disease activity, functional ability and quality of life and the medication costs in a naturalistic design. METHODS: All patients from the Dutch Rheumatoid Arthritis Monitoring (DREAM) register starting on tumour necrosis factor (TNF)alpha-blocking agents for the first time were monitored and assessed by trained research nurses every 3 months. The primary outcome was the Disease Activity Score (DAS28) course over the 12 months follow-up, analysed by linear mixed models. Secondary outcomes were the Health Assessment Questionnaire (HAQ), EuroQol five dimensions (EQ-5D) and the Short-Form 36 items (SF36) scores, and medication-related total costs. RESULTS: The DAS28 and SF-36 physical component scale decreased in all three medication groups over 12 months, but the decrease was larger for adalimumab and etanercept in comparison to infliximab (p<0.001). The analyses of the HAQ and the EQ-5D scores showed the same (non-significant) trend, namely that at 12 months, the functionality and quality of life was better for adalimumab and etanercept patients. With regard to the medication costs, infliximab treatment resulted in significantly higher costs over the follow-up period than treatments with either adalimumab or etanercept. The comparison between adalimumab and etanercept showed a significant difference in the 12-month DAS28 course (p = 0.031). There were no additional indications for differences in effectiveness or costs between adalimumab and etanercept. CONCLUSION: The evaluation of the effectiveness and costs showed that adalimumab and etanercept are more or less equal and favourable compared to infliximab in the first year of treatment.

RESUMO

OBJECTIVE: To determine whether assessment of antibodies directed against citrullin provides additional value in the diagnosis of rheumatoid arthritis (RA) in general practice. DESIGN: Retrospective. METHODS: In a 6-month period in 2004 (May-December), all sera sent to our laboratory for assessment of rheumatoid factor (RF-IgM), were also analysed for the presence of antibodies directed against citrullinated fibrinogen (anti-citrullin). We analysed 691 sera sent in by general practitioners using a homemade assay. To determine the disease classification, general practitioners were asked to provide information pertaining to the American College of Rheumatology disease classification criteria. The response was 97.6%. For patients who were referred to a rheumatologist in the last 2 years (December 2004-December 2006), the diagnosis of the rheumatologist was also considered in the analysis. RESULTS: A total of 28 patients (4%) were diagnosed with rheumatoid arthritis. Only 25% of these patients were positive for anti-citrullin, and only 25% were positive for RF-IgM. These 2 groups only partially overlapped. The positive and negative predictive values of anti-citrullin were 36 and 96%, respectively. CONCLUSION: The presence of anti-citrullin provided no additional value compared to rheumatoid factor in classifying RA in a general practice population.

RESUMO

Urate-lowering therapy (ULT) is a recommended life-long treatment for gout patients. However, despite these recommendations, recurrent gout attacks are commonly observed in clinical practice. The purpose of this study was to assess the levels of compliance and persistence to ULT in The Netherlands, in order to reflect on the current gout care delivered by health professionals. Anonymous prescription records were obtained from IQVIA's Dutch retrospective longitudinal prescription database, containing ULT dispensing data for allopurinol, febuxostat, and benzbromarone from November 2013 to July 2017. Compliance to ULT was determined by calculating the proportion of days covered (PDC) over 12 months. Persistence over 12 months was evaluated by determining the time to discontinuation, without surpassing a refill gap of > 30 days. Association of PDC and persistence with age, gender, and first prescriber were examined using beta regression- and cox-regression models, respectively. There were 45,654 patients who met the inclusion criteria. Overall, 51.7% of the patients had a ULT coverage of ≥ 80% of the days in 1 year (PDC ≥ 0.80), and 42.7% of the patients were still persistent after 1 year. Men, older patients, and patients whose first prescriber was a rheumatologist were more persistent and had a higher PDC. Our results show that medication adherence to ULT after 1 year is suboptimal, considering that current guidelines recommend ULT as a life-long treatment. Future studies addressing the reasons for treatment cessation and improving treatment adherence seem warranted.

RESUMO

OBJECTIVE: To explore the association between achieving favorable clinical outcomes and patients' perceived change in overall health status after 12 months of treat-to-target in patients with early rheumatoid arthritis (RA) and to identify determinants of subjective nonimprovement. METHODS: Baseline and 12-month data of patients included in the Dutch Rheumatoid Arthritis Monitoring remission induction cohort study with at least a moderate response (by European League Against Rheumatism criteria) after 1 year were selected for analysis. Logistic regression analysis was used to identify factors associated with nonimproved perceived overall health status at 12 months. RESULTS: At 12 months, 75 of 210 patients (35%) did not consider their health to have improved despite having achieved favorable clinical outcomes. Relative change from baseline in pain (Wald = 20.20; P < 0.01) and fatigue (Wald = 5.58; P = 0.02) was independently associated with nonimproved perceived overall health status. The results were similar when only patients with ≤1 swollen joint were analyzed. An improvement of 55% in pain measured on a visual analog scale was found to discriminate reasonably well between patients who considered their health to have improved versus patients who did not, with an area under the receiver operating characteristic curve of 0.70 (95% confidence interval 0.61-0.78). CONCLUSION: These results demonstrate that clinical improvements do not equate with improved subjective health for all patients. The association of nonimprovement with changes in pain and fatigue suggest that it might be worthwhile to monitor and address pain and fatigue in addition to and independently of disease activity in early RA.

RESUMO

Patients in real life may differ from those in clinical trials. The aim of this study is to report 5-year outcomes of a continuous treat-to-target (T2T) approach in patients with rheumatoid arthritis (RA) in daily clinical practice. In the Dutch RhEumatoid Arthritis Monitoring cohort, all patients with a clinical diagnosis of RA were treated according to a protocolled T2T strategy, aimed at 28-joint Disease Activity Score (DAS28) < 2.6. Outcomes were percentages of patients in distinct levels of disease activity, mean course of DAS28 and prevalence of sustained (drug-free) remission. Also, data on functional disability (Health Assessment Questionnaire) and health-related quality of life (Short-Form 36) were examined. Mean DAS28 improved from 4.93 (95% CI 4.81-5.05) at baseline to 2.49 (95% CI 2.35-2.63) after 12 months and remained stable thereafter. Percentages of patients at 12 months with DAS28 < 2.6 (remission), DAS28 ≥ 2.6 and ≤ 3.2 (low disease activity), DAS28 > 3.2 and ≤ 5.1 (moderate disease activity) and DAS28 > 5.1 (high disease activity) were 63, 16, 18 and 3%, respectively. Sustained remission (DAS28 < 2.6 during ≥ 6 months) was observed at least once in 84% of the patients and drug-free remission (DAS28 < 2.6 during ≥ 6 months after withdrawal of all disease-modifying anti-rheumatic drugs) in 36% of the patients. Functional disability and health-related quality of life significantly improved during the first 24 weeks. Continuous application of T2T in real-life RA patients leads to favourable disease- and patient-related outcomes.

RESUMO

OBJECTIVE: To study the agreement between patients' actual baseline assessments of pain and global health before treatment and retrospective assessments collected 2 weeks after treatment. METHODS: Data were collected in a prospective study of 200 rheumatology outpatients treated with a local corticosteroid injection. At baseline and 2-week follow-up, localized pain and global health were assessed on 100 mm visual analogue scales. The follow-up questionnaire was extended with a retrospective assessment of pain and global health before treatment. RESULTS: At follow-up patients slightly overestimated the severity of pain and global health before treatment. Actual and retrospective assessments were adequately correlated (pain: r(r(r(s) = 0.73; global health: r(s) = 0.67). Bland-Altman analysis showed that both pain and global health were characterized by high intra-individual variation between actual and retrospective assessments, with the 95% limits of agreement (-37.3 to 32.3 mm for pain and -49.7 to 37.8 mm for global health) far exceeding proposed values for minimal clinically important differences. CONCLUSION: Over a 2-week interval, patients' retrospective assessments of baseline pain and global health are fairly accurate and adequately correlated with actual baseline scores. At the group level, retrospective assessments can provide acceptable data on baseline pain and global health. The wide variability between actual and retrospective assessments, however, indicates that even over short time intervals there is poor individual agreement between the two methods.
