Pain and daily activities in rheumatoid arthritis.

Aim: The aim of this study was to describe experiences of pain and its relationship to daily activities in people with rheumatoid arthritis (RA). Method: Seven semi-structured focus group discussions were conducted with 33 men and women of different ages with RA. Data were analysed with content analysis. Results: Pain affected everyday life and may be a barrier to perform valued activities. Regarding the impact of pain on participation and independence, personal factors and the social environment were found to be important. It could be a struggle to find the right activity balance, since it was easy to be overactive, triggering subsequent elevation of pain levels. However, the participants also described activities as a mediator of pain and a distraction from it. Conclusion: The relationship between pain and daily activities in RA was complex. Pain as an impairment was expressed to be related to activity limitations and participation restrictions, as well as to contextual factors. These findings highlight the clinical importance of paying attention to the complexity of pain and its relation to daily activities and participation. Implications for Rehabilitation Pain in RA needs to be comprehensively analyzed and treated in the context of the patients’ perspective and needs. The relation between pain and performance of activities in RA highlights the importance of rehabilitative interventions to reduce pain in order to facilitate daily activity. The complexity of pain implies the need for multimodal approach in rehabilitation.

Sick Leave Before and After Diagnosis of Rheumatoid Arthritis ― A Report from the Swedish TIRA Project

Objective. Our study describes sick leave during 3 years before and 3 years after diagnosis of rheumatoid arthritis (RA) in relation to referents and identifies predictors for sick leave during the third year after diagnosis of RA. Methods. One hundred twenty patients (76% women) from the Swedish early RA study TIRA were included. Disease activity and disability were registered regularly during 3 years in TIRA. Referents were matched for sex, age, and home town. Sick leave data were obtained for patients 3 years before and 3 years after diagnosis and for the referents for the corresponding 6 years. Results. No differences were seen between patients and referents regarding sick leave during the first 2 years, whereas sick leave increased in patients 6 months before diagnosis, from 30% to 53%. During the 3 years after diagnosis, sick leave among patients was rather stable, varying between 50% and 60%, even though disability pension increased and sickness benefit decreased. Sick leave before diagnosis, disability 1 year after diagnosis, and type of work were identified as predictors for sick leave during the third year after diagnosis. Conclusion. Not surprisingly, sick leave in patients increased the year before diagnosis. Although disease activity and disability diminished after diagnosis, the patients’ sick leave remained essentially unchanged. Sick leave 3 years after diagnosis was foremost predicted by earlier sick leave, disability, and type of work.

Disease activity and disability in women and men with early rheumatoid arthritis (RA) : An 8-year followup of a Swedish early RA project

To compare women and men regarding the course of disease activity and disability over 8 years from diagnosis of recent‐onset rheumatoid arthritis (RA).

Multivariate relationships between pain intensity and other aspects of health in rheumatoid arthritis : cross sectional and five year longitudinal analyses (the Swedish TIRA project)

Objectives. This study analyses the relationships between pain intensity and other aspects of health commonly used to assess disease activity and disability in early rheumatoid arthritis and examines whether such relationships were different between women and men. Subjects and methods. This study included the 189 patients (69% women) with early RA (symptoms <12 months at diagnosis) still remaining in the Swedish TIRA cohort 5 years after inclusion. Disease activity and disability was assessed 3, 6, 12, 18, 24, 36, 48, and 60 months (M0-M60) after inclusion by erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), number of swollen and tender joints, physicians global assessment of disease activity (PGA), grip force average over 10 seconds (Grippit), Grip Ability Test (GAT), Signals of Functional Impairment (SOFI) in hand, lower limb and upper limb, Health Assessment Questionnaire (HAQ), and pain intensity measured with a visual analogue scale (VAS). The variables were divided into meaningful blocks according to the correlation structure in a principal component analysis (PCA) at M60. Using hierarchical partial least squares (PLS) analyses, this study investigated the blocks cross-sectionally to test for correlations with pain intensity at M0 and M60. The blocks at M0 were also used as predictors of pain intensity at M60 in a hierarchical PLS. Results. The strongest relationship was found between pain intensity and the second block, consisting of HAQ and SOFI-lower limb at the cross-sectional analyses in both women and men. The block representing disease activity (i.e., ESR, CRP, PGA, and swollen and tender joints) had the weakest relation to pain intensity. According to the longitudinal analyses, the disease activity variables (block 1) at M0 had the strongest relationship to pain intensity at M60 in men. In contrast, HAQ and SOFI-lower limb (block 2) at M0 had a strong relation to pain intensity in women.

Construct validity of the Assessment of Work Performance (AWP)

The instrument Assessment of Work Performance (AWP 1.1) can be used to assess an individuals skills during work performance - how efficient and appropriate a client performs a work task. The instrument is currently used by over 300 assessors working in a variety of work rehabilitation settings in Sweden, and it has been used with over 10,000 clients. In this study, the construct validity of the AWP 1.1 was tested with 364 assessments of clients with a variety of various work-related problems assessed by six occupational therapists in a Social Insurance Office in Sweden between 2004 and 2005. Principal Component Analysis shows construct validity of the AWP 1.1. Further, the findings indicate that the instrument is sensitive and discriminates between clients, and no gender related patterns were identified.

Differences in activity limitation, pain intensity, and global health in patients with rheumatoid arthritis in Sweden and the USA: a 5-year follow-up.

Objective: In this study we compared activity limitations, pain intensity, and global health in patients with rheumatoid arthritis (RA) in Sweden and the USA and aimed to determine whether nationality is associated with these outcomes. Methods: We used longitudinal data from the ‘Swedish TIRA project’ (n = 149) and the University of California, San Francisco (UCSF) RA panel study (n = 85). Data were collected annually concerning use of medications [disease-modifying anti-rheumatic drugs (DMARDs), biologics, and corticosteroids], morning stiffness, number of swollen joints, and number of painful joints. Three self-reported outcome measures were examined: pain intensity measured on a 0–100 visual analogue scale (VAS), activity limitation according to the Health Assessment Questionnaire (HAQ), and global health. To analyse the data, the Student’s t-test, the χ2-test, and the generalized estimating equation (GEE) method were used. Results: Nationality was significantly related to HAQ score and pain intensity, even after adjustment for covariates. The patients in the TIRA cohort reported a lower HAQ score and a higher pain intensity than the patients in the UCSF cohort. Nationality was not related to global health. Conclusion: Patients with RA should be assessed with awareness of the psychosocial and cultural context because disability seems to be affected by nationality. Further knowledge to clarify how a multinational setting affects disability could improve the translation of interventions for patients with RA across nationalities.

Dilemmas of participation in everyday life in early rheumatoid arthritis: a qualitative interview study (The Swedish TIRA Project)

Abstract Purpose: To explore the experiences of todays patients with early rheumatoid arthritis (RA) with respect to dilemmas of everyday life, especially regarding patterns of participation restrictions in valued life activities. Methods: A total of 48 patients, aged 20–63, three years post-RA diagnosis were interviewed using the Critical Incident Technique. Transcribed interviews were condensed into meaningful units describing actions/situations. These descriptions were linked to ICF participation codes according to the International Classification of Functioning, Disability and Health (ICF) linking rules. Results: Dilemmas in everyday life were experienced in domestic life, interpersonal interactions and relationships, community, social and civic life. Most dilemmas were experienced in domestic life, including participation restrictions in, e.g. gardening, repairing houses, shovelling snow, watering pot plants, sewing or walking the dog. Also many dilemmas were experienced related to recreation and leisure within the domain community, social and civic life. The different dilemmas were often related to each other. For instance, dilemmas related to community life were combined with dilemmas within mobility, such as lifting and carrying objects. Conclusions: Participation restrictions in today’s RA patients are complex. Our results underline that the health care needs to be aware of the patients’ own preferences and goals to support the early multi-professional interventions in clinical practice. Implications of Rehabilitation Today’s rheumatoid arthritis (RA) patients experience participation restrictions in activities not included in International Classification of Functioning, Disability and Health (ICF) core set for RA or in traditionally questionnaires with predefined activities. The health care need to be aware of the patients’ own preferences and goals to meet the individual needs and optimize the rehabilitation in early RA in clinical practice.

Symptoms of subordinated importance in fibromyalgia when differentiating working from non-working women

BACKGROUND The aim was to identify differences in self-reported symptoms among working (W) and non-working (NW) women, and to determine the most important biopsychosocial variables in differentiating one group from the other. METHOD A questionnaire was mailed to 524 members of a local chapter of the Swedish Rheumatology Association. A total of 362 persons responded (69%); 96% of which were women. Women older than 64 years and all men were excluded. The final study group consisted of 95 W, and 227 NW women. The questionnaire included data on demographics, employment, support, exercise, daily activities and symptoms. Data were analysed using univariate statistics and a partial least squares discriminant analysis (PLS-DA). RESULTS The results showed that 41% of the W and 42% of the NW women were/had been employed in service,care or business. The NW women reported a significantly higher severity of symptoms compared with the W women. The most important variable when differentiating the W from the NW women was social support from colleagues and employers. CONCLUSION To change prevailing attitudes and values towards persons with a work disability, a process of active intervention involving staff is needed. Educating employers as to how a disability may influence a work situation, and the importance of social support, can be improved.

Pain and activity limitations in women and men with contemporary treated early RA compared to 10 years ago: the Swedish TIRA project

Objectives: To study differences regarding pain and activity limitations during the 3 years following diagnosis in women and men with contemporary treated early RA compared with their counterparts who were diagnosed 10 years earlier. Method: This study was based on patients recruited to the Early Intervention in RA (TIRA) project. In the first cohort (TIRA-1) 320 patients were included in time for diagnosis during 1996–1998 and 463 patients were included in the second cohort (TIRA-2) during 2006–2009. Disease activity, pain intensity (Visual Analogue Scale, VAS), bodily pain (BP) in the 36-item Short Form Health Survey (SF-36), activity limitations (Health Assessment Questionnaire, HAQ), and medication were reported at inclusion and at follow-up after 1, 2, and 3 years. Results: Disease activity, pain, and activity limitations were pronounced at inclusion across both genders and in both cohorts, with some improvement observed during the first year after diagnosis. Disease activity did not differ between cohorts at inclusion but was significantly lower at the follow-ups in the TIRA-2 cohort, in which the patients were prescribed traditional disease-modifying anti-rheumatic drugs (DMARDs) and biological agents more frequently. In TIRA-2, patients reported significantly lower pain and activity limitations at all follow-ups, with men reporting lower pain than women. Women reported significantly higher activity limitations at all time points in TIRA-2. Conclusions: Pain and activity limitations were still pronounced in the contemporary treated early RA cohort compared with their counterparts diagnosed 10 years earlier and both of these factors need to be addressed in clinical settings.

Self-reported nonrestorative sleep in fibromyalgia - relationship to impairments of body functions, personal function factors, and quality of life.

Purpose The purpose of this study was: 1) to determine variables that might characterize good or bad sleep; and 2) to describe the relationship between sleep, impairment of body functions, personal function factors, and quality of life based on quality of sleep in women with fibromyalgia (FM). Methods This cross-sectional descriptive study included 224 consecutive patients diagnosed at a specialist center. These patients were mailed a questionnaire concerning sleep, body functions, personal factors, and health-related quality of life. In total, 145 completed questionnaires were collected. Results Using sleep variables (sleep quality, waking up unrefreshed, and tiredness when getting up), we identified two subgroups – the good sleep subgroup and the bad sleep subgroup – of women with FM. These subgroups exhibited significantly different characteristics concerning pain intensity, psychological variables (depressed mood, anxiety, catastrophizing, and self-efficacy), impairments of body functions, and generic and health-related quality of life. The good sleep subgroup reported a significantly better situation, including higher employment/study rate. The bad sleep subgroup reported a greater use of sleep medication. Five variables determined inclusion into either a good sleep or a bad sleep subgroup: pain in the evening, self-efficacy, anxiety, and according to the Short Form health survey role emotional and physical functioning. Conclusion This study found that it was possible to identify two subgroups of women with FM based on quality of sleep variables. The two subgroups differed significantly with respect to pain, psychological factors, impairments of body functions, and perceived quality of life, where the subgroup with bad sleep had a worse situation.
