  • Sickness absence among cancer patients in the pre-diagnostic and the post-diagnostic phases of five common forms of cancer
  • 2012
  • Ingår i: Supportive Care in Cancer. - : Springer. - 0941-4355 .- 1433-7339. ; 20:4, s. 741-747
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose The purpose of this study was to observe sickness absence before and after the cancer diagnosis among cancer patients with five common forms of cancer.Methods Using cohort data, we observed sick leave in the pre- and post-diagnostic phase among patients with colon, rectal, breast, prostate, or lung cancer (n = 2,738). We also identified reference subjects without cancer (total n = 12,246) who were individually matched for age and gender for each specific cancer cohort in order to compare sickness absence between patients with a specific form of cancer and the background population without cancer.Results Lung cancer patients had the highest increase in sick days both pre- and post-diagnosis and prostate cancer patients had the lowest increase. Irrespective of the form of cancer, cancer patients had significantly more sick days in the post-diagnostic phase compared to their reference subjects, ranging from 5 (prostate cancer) to 12 times the amount of sick days (colon and lung cancer). One year post-diagnosis, less than half of the cancer patients were on sick leave, except for lung cancer patients where 63% were still on sick leave.Conclusion Sick leave among cancer patients seems related not only to the cancer diagnosis and its treatment but also to the prodromal illness in the pre-diagnostic phase, especially for forms of cancer with heavier symptom burden such as colon and lung cancer. Although cancer results in substantial increase in sick leave, it is important to acknowledge that a major part of cancer patients return to work within 1 year after the cancer diagnosis.

  • A nurse-led rheumatology clinic’s impact on empowering patients with rheumatoid arthritis : A qualitative study
  • 2006
  • Ingår i: Nursing and Health Sciences. - Richmond, Australia : Wiley-Blackwell. - 1441-0745 .- 1442-2018. ; 8:133-9
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to describe a nurse-led rheumatology clinic’s impact on empowering patients with rheumatoid arthritis (RA). Rheumatoid arthritis is a chronic, inflammatory disease that attacks many joints, causing considerable functional restrictions for patients. Consequently, these patients are dependent on a wide variety of health-care services. A descriptive, qualitative design inspired by phenomenography was chosen. The conceptions were collected through interviews with 16 strategically selected patients with RA. Three descriptive categories comprising eight conceptions emerged: teaching (gaining insight and receiving information), regular review (receiving security, realizing regularity, and achieving accessibility), and attention (getting a holistic assessment, receiving coordinated care, and getting sufficient time). A nurse-led rheumatology clinic can be a source for empowering patients with RA to adopt new stances to alternative actions and achieve a higher level of faith in their own abilities.

  • Early increase in serum-COMP is associated with joint damage progression over the first five years in patients with rheumatoid arthritis
  • 2013
  • Ingår i: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 14
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Currently available biomarkers for the early tissue process leading to joint damage in rheumatoid arthritis are insufficient and lack prognostic accuracy, possibly a result of variable activity of the disease over time. This study represents a novel approach to detect an altered activity of the disease process detected as increasing serum-COMP levels over a short time and whether this would correlate with joint damage progression over the first 5 years of disease. Methods: In all, 349 patients from the Swedish BARFOT early RA study were examined. Serum-COMP was analysed by ELISA at diagnosis and after 3 months. Based on changes in serum-COMP levels, three subgroups of patients were defined: those with unchanged levels (change <= 20%) (N=142), decreasing levels (> 20%) (N=173) and increasing levels (> 20%) (N=34). Radiographs of hands and feet were obtained at inclusion, after 1, 2 and 5 years and scored according to Sharp van der Heijde (SHS). Radiographic progression was defined as increase in SHS by >= 5.8. Results: The group of patients with increasing COMP levels showed higher median change in total SHS and erosion scores at 1, 2 and 5 year follow-up compared with the groups with stable or decreasing COMP levels. Furthermore, the odds ratio of radiographic progression was 2.8 (95% CI 1.26-6.38) for patients with increasing COMP levels vs. patients with unchanged levels. The group of patients with increasing COMP levels had higher ESR at inclusion but there were no baseline differences between the groups for age, gender, disease duration, disease activity (DAS28), function (HAQ), CRP, nor presence of rheumatoid factor or anti-CCP. Importantly, neither did changes over the 3-month period in DAS28, HAQ, ESR nor CRP differ between the groups and these variables did not correlate to joint damage progression. Conclusion: Increasing serum-COMP levels between diagnosis and the subsequent 3 months in patients with early RA represents a novel indicator of an activated destructive process in the joint and is a promising tool to identify patients with significant joint damage progression during a 5-year period.

  • Serum levels of Cartilage Oligomeric Matrix Protein (COMP) increase temporarily after physical exercise in patients with knee osteoarthritis
  • 2006
  • Ingår i: BMC Musculoskeletal Disorders. - : Springer Science and Business Media LLC. - 1471-2474. ; 7
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: COMP (Cartilage oligomeric matrix protein) is a matrix protein, which is currently studied as a potential serum marker for cartilage processes in osteoarthritis (OA). The influence of physical exercise on serum COMP is not fully elucidated. The objective of the present study was to monitor serum levels of COMP during a randomised controlled trial of physical exercise vs. standardised rest in individuals with symptomatic and radiographic knee OA. Methods: Blood samples were collected from 58 individuals at predefined time points before and after exercise or rest, one training group and one control group. The physical exercise consisted of a one-hour supervised session twice a week and daily home exercises. In a second supplementary study 7 individuals were subjected to the same exercise program and sampling of blood was performed at fixed intervals before, immediately after, 30 and 60 minutes after the exercise session and then with 60 minutes interval for another five hours after exercise to monitor the short-term changes of serum COMP. COMP was quantified with a sandwich-ELISA (AnaMar Medical, Lund, Sweden). Results: Before exercise or rest no significant differences in COMP levels were seen between the groups. After 60 minutes exercise serum COMP levels increased (p<0.001). After 60 minutes of rest the serum levels decreased (p=0.003). Median serum COMP values in samples obtained prior to exercise or rest at baseline and after 24 weeks did not change between start and end of the study. In the second study serum COMP was increased immediately after exercise (p=0.018) and had decreased to baseline levels after 30 minutes. Conclusion: Serum COMP levels increased during exercise in individuals with knee OA, whereas levels decreased during rest. The increased serum COMP levels were normalized 30 minutes after exercise session, therefore we suggest that samples of blood for analysis of serum COMP should be drawn after at least 30 minutes rest in a seated position. No increase was seen after a six-week exercise program indicating that any effect of individualized supervised exercise on cartilage turnover is transient.

  • Patients' perceptions of drug dispensing in a rheumatological in-patient unit
  • 2005
  • Ingår i: Musculoskeletal Care. - London : John Wiley & Sons. - 1478-2189 .- 1557-0681. ; 3:4, s. 213-223
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction:The dispensing of drugs in medical care systems is, in most countries, strictly regulated, and nurses are responsible for distributing drugs to in-patients.Aim:To describe the perceptions of patients with rheumatic diseases regarding traditional drug dispensing during in-patient care and rehabilitation in a specialized rheumatological care unit.Method:Twenty in-patients who stayed in the Spenshult Hospital unit for 3-4 weeks and who were on continuous medication were chosen for the study. The phenomenographic approach was used for the collection and analysis of data.Findings:Three descriptive categories emerged - Relief, Active Participation and Dependence. These descriptive categories comprised: three perceptions for Relief (to experience security, to be served, to dare to bother), two for Active Participation (to rely on one's own ability, to search for knowledge) and two for Dependence (lack of independence, lack of information).Conclusion:The patients experienced relief due to the nurse assuming responsibility for the medication and its dispensation. Patients expressed a wish to be more active in the management of their medication, as they trusted their own ability. The patients articulated that they were dependent on the nurse to give them the correct medication and they also asked for more information about their medication.

  • In Patient Team Care Improved Health-Related Quality of Life for Patients with Rheumatic Diseases over Three and Six Months
  • 2006
  • Ingår i: Annals of the Rheumatic Diseases. - London : BMJ Books. - 0003-4967 .- 1468-2060. ; 65:Suppl. 2, s. 274-275
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: For measuring outcomes in team care, different aspects in the ICF (International Classification of Functioning) are relevant. Health-related quality of life as measured by SF-36 includes aspects of body function as well as activity and participation. HADS (Hospital Anxiety and Depression Scale) reflects more personal factors. Individuals with rheumatic diseases experience lower degree of health-related quality of life, compared with the general population.Objectives: To examine health-related quality of life as well as anxiety and depression in patients with rheumatic diseases directly after and three and six months after a period of three weeks in patient team based multiprofessional rehabilitation at a unit specialised for patients with different rheumatic diseases.Method: Quasi-experimental design with pre- and post-test in consecutive adult patients (Rheumatoid arthritis n=23, Spondylarthritides n=14, Osteoarthritis n=6, Other inflammatory rheumatic diseases n=10), one week before(n=55), one week after(n=53), three (n=40) and six months (n=36) after a period of three weeks of in patient team based multiprofessional care at a unit for rheumatic diseases. The instruments used for outcome measurements were the Short Form 36 Health questionnaire (SF-36) and the Hospital Anxiety and Depression Scale (HADS). Statistical analysis was done with the SPSS package 13.0. Differences between groups were evaluated with Wilcoxon signed rank test.Results: The patients reported worse outcome on the eight health scales in SF-36, at baseline and one week, three and six months after the rehabilitation, when comparing with the norm for the Swedish population. The mean values for SF-36 improved in all eight subscales one week after the rehabilitation period and six of the health scales obtained statistically significant improvement (p<0.05). Three and six months later there was still a statistically (p<0.05 for 3/8 subscales; Role Physical (RP), Vitality(VT) and Mental Health(MH)) and/or clinically significant (5/8 subscales; Physical function(PF), Bodily Pain(BP), General Health(GH), Social Fundtioning(SF) and Role Emotional(RE)) improvement as compared to the levels before the rehabilitation period. The levels for anxiety and depression as measured by HADS improved significantly (p<0.05) one week after the rehabilitation period as compared to baseline. Three and six months after the rehabilitation period, the levels were the same as at baseline.Conclusion: Earlier studies and this study have shown that people with rheumatic diseases experience reduced health-related quality of life and increased anxiety and depression. The result from this study showed that after a period of three weeks in patient team based multiprofessional rehabilitation, the experience of health-related quality of life was improved also after three and six months whereas the improvement in anxiety and depression returned to baseline after three and six months. Thus, improvements in health-related quality of life seem to reflect other aspects of the disease consquences than anxiety and depression.

    • Indicators of work role functioning (being at work, and being productive while at work) are important outcomes for persons with arthritis. As the worker productivity working group at OMERACT (Outcome Measures in Rheumatology), we sought to provide an evidence base for consensus on standardized instruments to measure worker productivity [both absenteeism and at-work productivity (presenteeism) as well as critical contextual factors].

  • Chronic widespread pain: A three year followup of pain distribution and risk factors
  • 2002
  • Ingår i: Journal of Rheumatology. - Toronto : Journal of Rheumatology Publishing Co. Ltd.. - 0315-162X .- 1499-2752. ; 29:4, s. 818-825
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To describe the change of pain reports over time in 3 cohorts derived from the general population: (1) no chronic pain (NCP, n = 1156); (2) chronic regional pain (CRP n = 502) and (3) chronic widespread pain (CWP; n = 242). To identify risk factors that predict the development or persistence of chronic widespread pain. Methods. A 3-year followup from 1995 to 1998 with postal questionnaire to 2425 subjects of both sexes aged 20-74 years on the west coast of Sweden. Results. At followup, a larger proportion of subjects with initial CRP compared to initial NCP reported CWP (16.4 and 2.2%, respectively; p < 0.001). The majority of subjects (56.9%) who primarily reported CWP remained in that group at followup, but 26.8% had changed status to CRP and 16.3% to NCP. The number of painful regions (7-12 vs 0 regions) reported at baseline was the strongest predictor for the development of CWP with an odds ratio (OR) of 12,13 (95% CI 4.47-32.88). The development of CWP was also predicted by higher age (OR = 3.13, 95% CI 1.47-6.69, age-group 59-74 years vs age-group 20-34 years), and a family history of chronic pain (OR = 1.87, 95% CI 1.14-3.07). A habit of drinking alcohol weekly (OR = 0.42, 95% Cl 0.21-0.85) compared to the habit of never or seldom drinking alcohol was protective, as well as having personal social support (OR = 0.49, 95% CI 0.28-0.85). The persistence of CWP was predicted by the number of painful regions (13-18 vs 1-6 regions) at baseline (OR = 7.56, 95% CI 2.17-26.30), and being an immigrant (OR 3.22, 95% CI 1.33-7.77). Conclusion. Although the overall prevalence of CWP was stable over a 3-year period there was a considerable variation on an individual basis. This variability in expressing CWP was moderately predicted by a combination of risk factors. the most important being the number of painful regions at baseline. Future research will need to show how useful the identified factors are in clinical practice and whether intervention aimed at changing these factors will improve pain outcome.

  • Chronic musculoskeletal pain, prevalence rates, and sociodemographic associations in a Swedish population study
  • 2001
  • Ingår i: Journal of Rheumatology. - Toronto : Journal of Rheumatology Publishing Co. Ltd.. - 0315-162X .- 1499-2752. ; 28:6, s. 1369-1377
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To estimate the prevalence of chronic regional and widespread musculoskeletal pain in a sample of the general adult population and study the association to age, sex, socioeconomic class, immigration, and housing area.METHODS: A cross sectional survey with a postal questionnaire to 3928 inhabitants on the west coast of Sweden.RESULTS: The age and sex adjusted prevalence of chronic regional pain (CRP) was 23.9% and chronic widespread pain (CWP) 11.4% among 2425 subjects who responded to the complete questionnaire. Odds ratio (OR) for CWP showed a systematic increasing gradient with age and was highest in the age group 59-74 yrs (OR 6.36, 95% CI 3.85-10.50) vs age group 20-34 yrs. CWP was also associated with female sex (OR 1.91, 95% CI 1.41-2.61), being an immigrant (OR 1.83, 95% CI 1.22-2.77), living in a socially compromised housing area (OR 3.05, 95% CI 1.48-6.27), and being an assistant nonmanual lower level employee (OR 1.92, 95% CI 1.09-3.38) or manual worker (OR 2.72, 95% CI 1.65-4.49) vs being an intermediate/higher nonmanual employee. OR for CRP showed a systematic increasing gradient with age and was highest in the age group 59-74 yrs (OR 2.22, 95% CI 1.62-3.05) vs age group 20-34 yrs. CRP was also associated with being a manual worker (OR 1.63, 95% CI 1.19-2.23) vs being an intermediate/higher nonmanual employee.CONCLUSION: Chronic musculoskeletal pain is common in the general population. Sociodemographic variables were overall more frequently and strongly associated with CWP than with CRP, which indicates different pathophysiology in the development or preservation of pain in the 2 groups.

  • Patterns of background factors related to early RA patients' conceptions of the causes of their disease
  • 2011
  • Ingår i: Clinical Rheumatology. - London : Springer Science and Business Media LLC. - 0770-3198 .- 1434-9949. ; 30:3, s. 347-352
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of the present study was to identify patterns of background factors related to the early RA patients' conceptions of the cause of the disease. Conceptions from a qualitative study formed the basis for the stratification of 785 patients from the Swedish EIRA study answering a question about their own thoughts about the cause to RA. Logistic regression analyses were used to explore the associations between patients' conceptions and relevant background factors: sex, age, civil status, educational level, anti-cyclic citrullinated peptide antibody (anti-CCP) and smoking habits. The results were presented as odds ratios (OR) with 95% confidence intervals (CI). A conception of family-related strain was strongly associated with being young (OR 0.50; 95% CI 0.33-0.78 for age 58-70 vs. 17-46), female (OR 0.38; 95% CI 0.25-0.60 for male vs. female) and having a high level of education (OR 2.15; 95% CI 1.54-3.01 for university degree vs. no degree). A conception of being exposed to climate changes was associated with being male (OR 1.99; 95% CI 1.24-3.22 for male vs. female), having a low level of education (OR 0.33; 95% CI 0.18-0.58 for university degree vs. no degree) and positive Anti-CCP (OR 1.72; 95% CI 1.03-2.87 for positive vs. negative Anti-CCP). Linking patients' conceptions of the cause of their RA to background factors potentially could create new opportunities for understanding the complexity of the aetiology in RA. Furthermore, this information is important and relevant in the care of patients with early RA.

  • Perception of tactile massage as a complement to other forms of pain relief in rheumatic disease
  • 2005
  • Ingår i: Musculoskeletal Care. - West Sussex, UK : John Wiley & Sons. - 1478-2189 .- 1557-0681. ; 3:3, s. 157-167
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To investigate how patients with rheumatic disease perceive tactile massage as a complement to other pain alleviation methods.Methods: A phenomenographic approach with semi-structured interviews was employed on a strategic sample of 14 patients with various rheumatic diseases, both inflammatory and non-inflammatory, who had been admitted to Spenshult Rheumatic Hospital.Results: Three descriptive categories with a total of nine conceptions emerged. The descriptive categories were: experiencing alleviation, experiencing trust, and gaining insight. Experiencing alleviation described how patients experience relaxation, pleasure and respite. Experiencing trust described how patients experience a sense of security, confirmation and inner peace. Gaining insight described how patients get to know themselves, see possibilities, and experience wholeness.Conclusions: When caring for patients who have a chronic illness involving considerable changes to their lives, it is important for health professionals not only to be aware of their physical needs but also to take account of the whole person. This study demonstrates the importance of offering patients a complement to conventional treatment. Tactile massage is a method that promotes a holistic view of patients with chronic pain as well as allowing them to find a new focus in terms of the disease and how they cope with it in their daily lives.

  • Disease course, outcome, and predictors of outcome in a population-based juvenile chronic arthritis cohort followed for 17 years
  • 2013
  • Ingår i: Journal of Rheumatology. - : The Journal of Rheumatology. - 0315-162X .- 1499-2752. ; 40:5, s. 715-724
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To investigate disease course, outcome, and predictors of outcome in an unselected population-based cohort of individuals diagnosed with juvenile chronic arthritis (JCA) followed for 17 years. METHODS: The cohort consisted of 132 incidence JCA cases identified 1984-1986 according to EULAR criteria. At 5-year followup, 129 individuals underwent joint assessment, laboratory measurements, radiographic examination, and medication and functional assessment. At 17-year followup, 86 were examined with joint assessment, laboratory measurements, medication assessment, Health Assessment Questionnaire (HAQ), Keitel functional test (KFT), and Medical Outcomes Study Short Form-36 (SF-36). RESULTS: At 17-year followup, 40% were in remission, 44% changed subgroups, median HAQ score was 0.0 (range 0.0-1.5), and median KFT was 100 (range 54-100). SF-36 scores were significantly lower compared to a reference group. Thirty-nine percent of those in remission at 5-year followup were not in remission at 17-year followup. In multivariate analyses of variables from the 17-year followup: remission was predicted by remission at 5-year followup (OR 4.8); HAQ > 0 by rheumatoid factor (RF)-positivity at 5-year followup (OR 3.6); KFT < 100 by nonremission (OR 11.3); and RF-positivity (OR 5.6) at 5-year followup; and the SF-36 physical component summary score above average of the reference group by remission at 5-year followup (OR 5.8). CONCLUSION: This longterm study of 86 individuals with JCA showed large variability of disease courses and of impaired health-related quality of life. Sixty percent were not in remission at 17-year followup. Longterm outcome was best predicted by and associated with characteristics at 5-year followup rather than those at onset.

  • Magnetic resonance imaging of the knee in chronic knee pain. A 2-year follow-up
  • 2001
  • Ingår i: Osteoarthritis and Cartilage. - : Elsevier BV. - 1063-4584. ; 9:5, s. 473-480
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The aim of the study was to evaluate the change over time of cartilage defects, subchondral lesions and meniscal abnormalities of the knee using magnetic resonance (MR) imaging with a 2-year interval in patients with chronic knee pain. Design: In the format of a prospective study of early osteoarthritis (OA), the signal knee (most painful at the inclusion in the study 1990) in 47 individuals, 25 women and 22 men (aged 41-57 years, median 50), with chronic knee pain, with or without radiographically determined knee OA, were examined using MR imaging on a 1.0 T imager with a 2-year interval (median 25 months, range 21-30). Cartilage defects, subchondral lesions and meniscal abnormalities were recorded and compared in blind between the examinations. Results: Five new cartilage defects and eight subchondral lesions appeared during the 2-year interval. Seven defects and seven subchondral lesions disappeared during the same time. Thirty-two out of 93 cartilage defects (34%) and 19 out of 32 subchondral lesions (59%) displayed an increase or a decrease in size over time. A meniscal abnormality appeared in three locations, and disappeared in none. In 14 out of 54 locations (26%) with a meniscal abnormality an increase or a decrease of the abnormality was recorded over time and no abnormality decreased. Conclusions: After the 2 years of observation it was possible to register, using MR imaging, the appearance, increase, decrease and disappearance of cartilage defects, subchondral lesions and meniscal abnormalities in middle-aged people with chronic knee pain. This has to be considered in studies of the natural course of knee CA as well as in studies of the intraarticular effect of pharmacological treatment aiming at cartilage repair or protection.

  • Health care utilization among individuals who die by suicide as compared to the general population : a population-based register study in Sweden
  • 2022
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 22:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Globally, 700 000 people die every year by suicide. Health care consultation patterns the period before suicide could be one potential way to identify people at risk for suicide. Therefore, this study examines health care patterns up to one year prior to the suicide by age, sex and prior diagnoses and specifically investigates if and how this differs from the general population of Skåne, Sweden.METHODS: This cohort study includes all individuals, aged 15 and older, that died by suicide in Region Skåne, Sweden from 2004 to 2015 (n = 1653). The individuals were identified through the Cause of death register and then linked to the Skåne healthcare register. Health care data was analyzed as proportions consulting different types of health care the month and year preceding the suicide, we also investigated the impact of age, sex and the occurrence of prior psychiatric and pain diagnoses. Additionally, we compared the proportion of consulting care among the suicide victims and the general population of Skåne.RESULTS: In the month before their death, 53% of the suicide victims had any health care consultation, compared with 20% in the general population of Skåne, a given month (p < 0.0001). The corresponding figures for the year prior to suicide was 86% among those who died by suicide, compared to 69% in the general population of Skåne, a given year (p < 0.0001). Women, and those having a documented history of psychiatric diagnosis were more likely to have health care consultations in the month and year preceding suicide (p < 0.001), compared to men and suicide victims without a history of psychiatric disease. Older adults that died by suicide, were less likely to consult psychiatric care compared to the younger suicide victims (p < 0.001).CONCLUSION: A majority of the suicide victims consulted health care in the near time before death and the proportion of seeking health care was significantly higher than in the general population of Skåne and higher among female suicide victims as compared to males. Alternative preventive screening measures should be considered for individuals consulting health care, especially for older people and individuals outside the psychiatric care.

  • Utilization of healthcare and prescription medicines after non-pharmacological interventions for depression - A 3-year register follow-up of an RCT in primary care
  • 2022
  • Ingår i: Preventive Medicine Reports. - : Elsevier. - 2211-3355. ; 25
  • Tidskriftsartikel (refereegranskat)abstract
    • Depression is a common, recurrent disorder. There is a need for readily available treatments with few negative side effects, that demands little resources and that are effective both in the short- and long term. Our aim was to investigate the long-term effectiveness of two different interventions; physical exercise and internet-based cognitive behavioural therapy (internet-CBT), compared to usual care in patients with mild to moderate depression in a Swedish primary care setting. We performed a register-based 3-year follow-up study of participants in the randomized controlled trial REGASSA (n = 940) using healthcare utilization and dispensed medicines as outcomes. We found no difference between the three groups regarding proportion of participants consulting healthcare due to mental illness or pain during follow-up. Regarding number of consultations, there was no difference between the groups, except for consultations related to pain. For this outcome both treatment arms had significantly fewer consultations compared to usual care, during year 2-3, the risk ratio (RR) for physical exercise and internet-CBT was 0.64 (95% CI = 0.43-0.95) and 0.61 (95% CI = 0.41-0.90), respectively. A significantly lower proportion of patients in both treatment arms were dispensed hypnotics and sedatives year 2-3 compared to the usual care arm, RR for both physical exercise and internet-CBT was 0.72 (95% CI = 0.53-0.98). No other differences between the groups were found. In conclusion, considering long-term effects, both physical exercise and internet-CBT, being resource-efficient treatments, could be considered as appropriate additions for patients with mild to moderate depression in primary care settings.

    • INTRODUCTION: Assessing work ability and sickness certification are considered problematic by many physicians and education and implementation of guidelines to improve knowledge and skills has been requested. Our aim was to study the association between such interventions and physicians' sick-listing practices.METHODS: A web-based questionnaire was sent to all physicians working in primary care, psychiatry, orthopedics/rheumatology in the southern region of Sweden before (in 2007 to 1,063 physicians) and after (in 2009 to 1,164 physicians) educational interventions in insurance medicine were offered.RESULTS: With a response rate of 58%, half of the physicians (51%) reported to work at a clinic with a sick-listing policy in 2009 compared with 31% in 2007. Primary care physicians (OR 12.4) and physicians who had participated in educational interventions in insurance medicine (OR 2.4) more often had a sick-listing policy at the clinic. Physicians with a longer medical experience (OR 0.7) and those with support at the clinic (OR 0.3) and the possibility to extend time if needed (OR 0.4) were less likely to report of problematic cases while primary care physicians were (OR 2.9). On the contrary, physicians who reported to rarely have the possibility to extend time when handling problematic cases were more likely to issue a higher number of sickness certificates.CONCLUSIONS: The sick-listing process is often viewed as problematic and more often by primary care physicians. Benchmarking and education in insurance medicine together with the possibility to allocate extra time if encountering problematic cases may facilitate sick-listing practice.

  • Revision in previously satisfied knee arthroplasty patients is the result of their call on the physician, not on pre-planned follow-up : a retrospective study of 181 patients who underwent revision within 2 years
  • 2005
  • Ingår i: Acta Orthopaedica. - : Medical Journals Sweden AB. - 1745-3674 .- 1745-3682. ; 76:6, s. 785-90
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Degree of satisfaction with a knee arthroplasty is said to be correlated to reduced pain and better function. During a validation of the Swedish Knee Arthroplasty Register in 1997, previously operated patients were asked how satisfied they were with their knee. A subgroup of "satisfied" patients was identified who underwent revision within 2 years of having expressed satisfaction. Our aim was to study the revision diagnosis, to determine whether the problem leading to revision had been discovered as a result of routine follow-up, and also to find out when the symptoms leading to revision had started.METHODS: We retrospectively studied the medical records of 181 patients (181 knees), with a median age of 74 (31-88) years. 68% were women and the median time between primary operation and revision was 8 (3-21) years.RESULTS: Aseptic loosening (74/181) was the most common diagnosis. 2 cases were revised as a result of routine follow-up. 44% of the medical records included reports of pain in the replaced knee prior to answering the satisfaction questionnaire.INTERPRETATION: Few patients were admitted to knee revision surgery due to medical findings discovered during routine follow-up. The term "satisfaction" must be interpreted with care, as it seems to have a more complex meaning for the patients than absence of knee pain.

    • OBJECTIVE: To study the rate of common comorbidities and cardiovascular disease in patients with ankylosing spondylitis (AS) compared with the general population seeking health care.METHODS: This cohort study included 935 subjects (67% men) ages ≥20 years diagnosed with AS and the adult background population in Southern Sweden. During 2004 to 2007 we recorded the occurrence of physicians' diagnostic codes for a select number of comorbidities commonly associated with AS and cardiovascular disease and risk factors. We obtained standardized morbidity-rate ratios (SMRs) by dividing the observed morbidity rate in AS patients by the expected rate based on the corresponding rate of the disease in the general population of the county seeking health care.RESULTS: The highest SMRs were found for uveitis (34.35, 95% confidence interval [95% CI] 28.55-40.98) and inflammatory bowel disease (9.28, 95% CI 7.07-11.97). Also, we found increased SMRs for ischemic heart diseases (2.20, 95% CI 1.77-2.70), hypertension (1.98, 95% CI 1.72-2.28), and diabetes mellitus (1.41, 95% CI 1.10-1.78). Furthermore, the SMRs for psoriasis, osteoporosis, and atrioventricular blocks were also statistically significantly elevated.CONCLUSION: Inflammatory diseases affecting the eye and the digestive system were the most notable comorbidities in AS patients, but the rate for cardiovascular disease was also high. Using comprehensive longitudinal population-based register data is a promising tool to evaluate the excess consultation rate and total burden of rheumatic disease on patients and society.

  • Smoking is associated with a worse self-reported health status in patients with psoriatic arthritis: data from a Swedish population-based cohort
  • 2015
  • Ingår i: Clinical Rheumatology. - London : Springer Science and Business Media LLC. - 0770-3198 .- 1434-9949. ; 34:3, s. 579-583
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim was to study possible associations between smoking habits and self-reported clinical features in a large population-based cohort of patients with psoriatic arthritis (PsA). All subjects with PsA who had sought health care in the period 2003-2007 were identified using a regional health-care register. In 2009, all those identified who were 18 years of age or more (n = 2,003) were sent a questionnaire with questions on smoking, health-related quality of life [EuroQol five-dimension (EQ-5D)questionnaire], function [Health Assessment Questionnaire (HAQ)], pain, fatigue, and global health. We performed age- and sex-adjusted regression analysis to compare health status outcomes in never and ever smokers. Altogether, 1,185 subjects (59 %) returned the questionnaire. Mean age was 57 years (SD 13.5), and 58 % were women; 38 % were never smokers and 62 % were ever smokers. Mean age at disease onset was 38.2 years (SD 13.2) and 41.2 years (SD 13.6), respectively (p = 0.001). In age- and sex-adjusted data, ever smokers reported worse EQ-5D (p = 0.009); worse reports of global health (p = 0.01), pain (p = 0.01), and fatigue (p = 0.04); and a higher number of painful body regions (p = 0.04) compared to never smokers. In this population-based PsA cohort, patients who were ever smokers reported worse health status than never smokers. Besides being a possible result of a worse PsA in ever smokers, impaired health status could also be an effect of unstudied comorbidities. Further longitudinal studies are needed to gain a better understanding of cause and effect. However, smoking cessation should be recommended because of general health considerations as well as disease-specific issues.

    • Background: In subjects with early axial Spondyloarthritis (SpA) smoking has recently been associated with earlier onset of disease, worse lesions of the sacroiliac joints and in later stages syndesmophyte progression. The aim was to study associations of smoking habits with self-reported information in a large population based cohort of patients with axial SpA.Methods: A cross-sectional questionnaire survey performed in 2009 included all health care seeking subjects aged >18 years with a diagnosis of SpA according to ICD 10 codes identified by a regional health care register (n=3711). Smoking habits were studied in patients with ankylosing spondylitis (AS, ICD M45) and in patients who fulfilled criteria for “non AS axial SpA” (without having one of AS). Criteria for non AS axial SpA were based on data from the questionnaire: pain for 3 months or more during the last 12 months together with 2 or more features out of 5 (inflammatory back pain, history of psoriasis, uveitis/tendinitis, inflammatory bowel disease or heredity). The questionnaire included data on smoking (never smokers vs. ever smokers), disease activity (BASDAI) physical function (BASFI), general health (BAS-G) all measured with numerical rating scales 0-10 (best to worst), health related quality of life (EQ-5D, 0-1 worst to best), pain, fatigue (numerical rating scales 0-10 best to worst) and number of painful regions noted on a pain mannequin (0-16 best to worst). Linear regression analysis was performed and all data were controlled for sex and age.Results: Response rate was 76% whereof 2167 (58%) returned the questionnaire and 18% declined participation in the study. 598 subjects had an AS diagnose and 572 fulfilled the criteria for non AS axial SpA.The AS group had a mean age of 54 (SD14) years and 35% were women. Never smokers constituted 48% of the AS group. Ever smokers had worse scores in all studied variables compared with never smokers.The linear regression analysis showed that ever smokers in the AS group had worse self-reported scores in BASDAI with age-sex adjusted parameter estimate (B) = 0.60 (95% CI 0.21 ; 1.00), BASFI B = 0.51 (95% CI 0.11 ; 0.91) and fatigue B = 0.51 (95% CI  0.06 ; 1.00) . There was a tendency to worse scores for ever smokers also in EQ-5D B = -0.04 (95% CI -0.09 ; 0.001)Mean age in the non AS axial SpA group was 55 (SD 14) years and 68% were women. Never smokers constituted 38% of this group. Also in the non AS axial SpA group the linear regression analysis showed that ever smokers had worse self-reported scores in BASDAI with age-sex adjusted parameter estimate (B) = 0.59 (95% CI 0.23 ; 0.94), BASFI B = 0.59 (95% CI 0.17 ; 1.00), pain B = 0.45 (95% CI 0.08 ; 0.82) and fatigue B = 0.43 (95% CI  0.03 ; 0.83), no of painful areas B = 0.73 (95% CI  0.06 ; 1.46) and also in EQ-5D B = -0.06 (95% CI -0.11 ; -0.002).                                                                                                                                                 Conclusion: In a large population based axial SpA cohort, both patients with AS and non AS axial SpA who were ever smokers reported worse clinical features compared with never smokers.

    • Background/Purpose: Smoking has been found to be associated with an increased risk of developing psoriatic arthritis (PsA)1. The purpose of this study was analyse possible associations of smoking habits with self-reported clinical features in a large population based cohort of patients with a diagnosis of PsA.Methods: All health care seeking subjects with a diagnose of PsA according to ICD 10 codes (given at least once by a rheumatologist/internist or twice by any other physician) were identified by a regional health care register during 2003-20072. In 2009 all identified subjects aged 18 years or older (n=2003) were invited to participate in a cross sectional questionnaire survey. The questionnaire included self-reported data on smoking (never smokers or ever smokers), age at disease onset, physical function (HAQ, 0-3 best to worst), pain, fatigue and global health (numerical rating scales 0-10 best to worst) health related quality of life (EQ-5D, 0-1 worst to best), and number of painful regions noted on a pain mannequin (0-16, best to worst). Linear regression analysis was performed and all data were controlled for sex and age.Results: Response rate was 77% whereof 369 patients (18%) declined participation and 1185 (59%) returned the questionnaire,  mean age 57.5 (SD 13.5) years and 58% were women. 1173 subjects responded to the smoking question whereof 448 (38%) were never smokers and 725 (62%) were ever smokers. Mean age at disease onset was 42.3 (SD 13.4) years in never smokers vs. 46.0 (SD 13.2) in ever smokers. Never smokers vs. ever smokers had mean HAQ 0.59 (SD 0.6) vs. 0.71 (SD 0.6),  mean pain 3.9 (SD 2.4) vs.4.4 (SD 2.5),  mean fatigue 4.4 (SD 2.8) vs. 5.0 (SD 2.7),  mean global health 3.9 (SD 2.4) vs. 4.4 (SD 2.3), mean EQ-5D 0.68 (SD 0.23) vs. 0.63 (SD 0.26) and mean no of painful regions were 7.2 (SD 4.0) vs. 7.9 (SD 4.3).The regression analysis showed that ever smokers had worse pain with age-sex adjusted parameter estimates (B) = 0.38 (95% CI 0.09 ; 0.67), worse fatigue B = 0.34 (95% CI 0.02 ; 0.66), worse global health B = 0.36 (95% CI 0.09 ; 0.64), worse EQ-5D B = -0.04 (95% CI -0.07 ; -0.01) and an increased no of painful regions B = 0.54 (95% CI 0.02 ; 1.07) compared with never smokers.Conclusion: In this population based PsA cohort, patients who were ever smokers reported worse clinical features compared with never smokers. Further longitudinal studies are needed to better understand cause and effect. However, smoking cessation should be recommended due to general health perspectives and also due to disease specific issues.

  • Validation of the Rheumatoid and Arthritis Outcome Score (RAOS) for the lower extremity
  • 2003
  • Ingår i: Health and Quality of Life Outcomes. - : Springer Science and Business Media LLC. - 1477-7525. ; 48:9 Suppl. S, s. 687-687
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Patients with inflammatory joint diseases tend due to new treatments to be more physically active; something not taken into account by currently used outcome measures. The Rheumatoid and Arthritis Outcome Score (RAOS) is an adaptation of the Knee injury and Osteoarthritis Outcome Score (KOOS) and evaluates functional limitations of importance to physically active people with inflammatory joint diseases and problems from the lower extremities. The aim of the study was to test the RAOS for validity, reliability and responsiveness. METHODS: 119 in-patients with inflammatory joint disease (51% RA) admitted to multidisciplinary care, mean age 56 (+/-13), 73% women, mean disease duration 18 (+/-14) yr were consecutively enrolled. They all received the RAOS, the SF-36, the HAQ and four subscales of the AIMS2 twice during their stay for test of validity and responsiveness. Test-retest reliability of the RAOS questionnaire was calculated on 52 patients using the first or second administration and an additional mailed questionnaire. RESULTS: The RAOS met set criteria of reliability and validity. The random intraclass correlation coefficient (ICC 2,1) for the five subscales ranged from 0.76 to 0.92, indicating that individual comparisons were possible except for the subscale Sport and Recreation Function. Inter-item correlation measured by Cronbach's alpha ranged from 0.78 to 0.95. When measuring construct validity the highest correlations occurred between subscales intended to measure similar constructs. Change over time (24 (+/- 7) days) due to multidisciplinary care was significant for all subscales (p < 0.001). The effect sizes ranged from 0.30-0.44 and were considered small to medium. All the RAOS subscales were more responsive than the HAQ. Some of the SF-36 subscales and the AIMS2 subscales were more responsive than the RAOS subscales. CONCLUSION: It is possible to adapt already existing outcome measures to assess other groups with musculoskeletal difficulties in the lower extremity. The RAOS is a reliable, valid and responsive outcome instrument for assessment of multidisciplinary care. To fully validate the RAOS further studies are needed in other populations.

  • Focus on Chronic Disease through Different Lenses of Expertise : Towards Implementation of Patient-Focused Decision Support Preventing Disability: The Example of Early Rheumatoid Arthritis
  • 2009
  • Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
    • Introduction: Rheumatoid arthritis (RA) is a chronic inflammatory disease. Treatment strategies emphasize early multi-professional interventions to reduce disease activity and to prevent disability, but there is a lack of knowledge on how optimal treatment can be provided to each individual patient.Aim: To elucidate how clinical manifestations of early RA are associated to disease and disability outcomes, to strive for greater potential to establish prognosis in early RA, and to facilitate implementation of decision support through analyses of the decision-making environment in chronic care.Methods: Multivariate statistics and mathematical modelling, as well as field observations and focus group interviews.Results: Decision support: A prognostic tree that predicted patients with a poor prognosis (moderate or high levels of DAS-28) at one year after diagnosis had a performance of 25% sensitivity, 90% specificity and a positive predictive value of 76%. Implementation of a decision support application at a rheumatology unit should include taking into account incentive structures, workflow and awareness, as well as informal communication structures. Prognosis: A considerable part of the variance in disease activity at one year after diagnosis could be explained by disease progression during the first three months after diagnosis. Using different types of knowledge – different expertise – prior to standardized data mining methods was found to be a promising when mining (clinical) data for new patterns that elicit new knowledge. Disease and disability: Women report more fatigue than men in early RA, although the difference is not consistently significant. Fatigue in early RA is closely and rather consistently related to disease activity, pain and activity limitation, as well as to mental health and sleep disturbance.Conclusion: A decision tree was designed to identify patients at risk of poor prognosis at one year after the diagnosis of RA. When constructing prediction rules for good or poor prognosis, including more measures of disease and disability progressions showed promise. Using different types of knowledge – different lenses of expertise – prior to standardized data mining methods was also a promising method when mining (clinical) data for new patterns that elicit new knowledge.

    • A Pd-MOS structure has been developed which has proven to be sensitive to hydrogen both in air at atmospheric pressures and in UHV. The ability to work over a wide pressure range makes it an interesting component in, e.g., the study of catalytic reactions involving hydrogen on metal surfaces. Here we demonstrate the hydrogen sensitivity of such a structure over a pressure range of 5x10-11 to 2 Torr.

    • The interaction of acetylene and ethylene with a clean and oxygen covered Pd surface has been studied at a temperature of 473 K. The measurements were performed on a hydrogen sensitive Pd-MOS structure making it possible to obtain direct information on the dissociation of both hydrogen and oxygen containing species on a palladium surface. Desorption studies were also performed as well as ultraviolet photoelectron spectroscopy and work function measurements. The studies show that both acetylene and ethylene adsorb dissociatively at this temperature leaving mainly carbon on the surface. When an oxygen covered Pd surface is exposed to C2H2 or C2H4 carbon dioxide and water will be formed and desorb until the surface is oxygen free. In the case of acetylene the presence of preadsorbed oxygen does not block or prevent the C2H2 dissociation on the surface. For C2H4, a large preadsorbed oxygen coverage ( 0.45) will have an impeding effect on the dissociation. The CO2 desorption is oxygen coverage dependent contrary to the H2O desorption. This is due to the fact that hydrogen has a large lateral mobility on the surface while carbon has not. Both the CO2 and H2O reactions are, however, due to the same type of mechanisms.

    • The photodissociative splitting of water has been studied in gas phase on a plane solid surface. A hydrogen sensitive Pd‐metal‐oxide‐semiconductor (MOS) structure was coated with 1–2 nm TiOx and exposed to water vapor and ultraviolet light. A natural separation of the produced hydrogen and oxygen occurs over the Pd film of the structure and the produced hydrogen is monitored by the electric behavior of the MOS device. The results suggest that suitably treated thin Pd membranes may be of interest for studying the continuous photodissociation of water.

    • The polycrystalline Pd surface of a hydrogen sensitive palladium‐silicon dioxide‐silicon [Pd‐MOS (metal‐oxide‐semiconductor)] structure has been exposed to small unsaturated hydrocarbons in the temperature range 300–500 K. Apart from the hydrogen response of the Pd‐MOS structure also work function (ΔΦ) and electron energy‐loss studies were performed. At 500 K the hydrocarbons dissociate completely upon adsorption and produce a surface with atomically adsorbed carbon. The Pd‐MOS structure can be used to observe both the dehydrogenation of the hydrocarbon molecules and the process of carbon adsorbing on the palladium surface. The sticking coefficient at this temperature for all hydrocarbons is close to unity. Furthermore, the hydrogen sensitivity of the structure is not drastically reduced by the adsorbed carbon. If the hydrocarbon adsorption is performed at 300 K there is still, at least on the initially clean surface, a large dehydrogenation. The dissociation is, however, not at all complete and there are considerable amounts of hydrocarbon species adsorbed for each gas. The induced work function shifts due to the different hydrocarbons vary from -1.0 to -1.7 eV. The hydrogen sensitivity of the Pd‐MOS structure is reduced for growing hydrocarbon coverages and disappears completely for work function shifts of -1.7 eV.

    • Isothermic desorption studies where an oxygen covered polycrystalline Pd surface (T = 325–575 K) is exposed to small unsaturated hydrocarbons have been performed. The studied gases were acetylene, propene, propadiene, propyne, butene, butadiene, butyne, and also for comparison hydrogen. Electron energy loss spectroscopy (EELS) was available for adsorbate studies and a hydrogen sensitive Pd-MOS structure was used as a sample. The temperature limit for total dissociation is observed to decrease slightly for an oxygen covered surface compared to the clean surface. On an oxygen covered surface the dissociation is complete above 400 K and the reaction products are H2O, CO2, and adsorbed C. Varying the adsorption temperature, the carbon dioxide production is not detectable at room temperature, where all carbon is adsorbed and only water is formed, but increases to reach a constant level above 475 K. For temperatures above 400 K the licking coefficient is close to unity and there is no blocking due to preadsorbed oxygen (as there is for H2). Both the water and carbon dioxide formations are of Langmuir-Hinshelwood type but while the H2O desorption rate is found to depend only on impinging hydrocarbon flux the CO2 desorption rate depends also on the oxygen coverage.

  • The H2-O2 reaction on palladium studied over a large pressure range : Independence of the microscopic sticking coefficients on surface condition
  • 1985
  • Ingår i: Surface Science. - : Elsevier BV. - 0039-6028 .- 1879-2758. ; 152/153, s. 559-
  • Tidskriftsartikel (refereegranskat)abstract
    • We have studied the H2---O2 reaction on Pd over a large pressure range by letting the reaction take place on the Pd gate of a Pd-MOS structure. By measuring shifts in the capacitance versus voltage (C(V)) curve of the structure, the variation of the “free” hydrogen atom concentration can be monitored during the reaction. By combining these results with surface potential measurements and with photoelectron spectroscopy, we find a critical ratio of 0.4 where the surface turns from being oxygen dominated to being hydrogen dominated. The critical ratio is independent of the absolute pressures and of surface condition and shows no significant temperature dependence in the temperature range 50–200°C. This implies that hydrogen and oxygen have similar sticking coefficients at both clean and technical Pd surfaces. The conclusion is drawn that hydrogen (and oxygen) dissociation on Pd is a property of the Pd atom or cluster of Pd atoms and is not critically dependent on any long-range order parameter such as the surface electronic density of states.

    • Different strategies have been used to stimulate a return to work (RTW) among individuals suffering from long-term ailments. In Sweden a new law on "resting disability pension" permits disability pensioners to go back to work without jeopardising their benefits. In this study different variables related to RTW during 2000 by means of this legislation were identified among disability pensioners with musculoskeletal disorders. Individuals in the study group, when compared to a control group, had more often been disability pensioners for several years, had additional education, estimated their previous job to have been physically strenuous to a lesser degree, were more satisfied with the treatment at the social insurance office and had a more positive self-image. This study shows that it may be meaningful to continue/resume rehabilitation efforts and to try to motivate an individual suffering from musculoskeletal disorders to return to work even after several years as a disability pensioner.

  • Prevalence and incidence of rheumatoid arthritis in southern Sweden 2008 and their relation to prescribed biologics.

    • Objectives. To gain updated estimates of prevalence and incidence of RA and proportion on biological treatment in southern Sweden. Methods. Inpatient and outpatient health care provided to residents in the southernmost county of Sweden (1.2 million inhabitants) is registered in the Skåne Health Care Register (SHCR). We identified residents aged >/=20 years who had received a diagnosis of RA at least twice during 2003-08. Valid point prevalence estimates by 31 December 2008 were obtained by linkage to the Swedish population register, and information on biological treatment was obtained from the South Swedish Arthritis Treatment Group register. We also tested our estimates of RA occurrence in a series of sensitivity analyses to investigate the effect of altered case criteria and the uncertainty generated by clinical visits without diagnoses. Results. The prevalence of RA in adults was estimated to 0.66% (women = 0.94%, men = 0.37%). The prevalence peaked at age 70-79 years (women = 2.1%, men = 1.1%) before dropping in those aged >/=80 years. Of prevalent cases, 20% had ongoing biological treatment, a percentage that was highest in women aged 40-49 years (36%). The incidence of RA in 2008 was estimated as 50/100 000 (women = 68/100 000, men = 32/100 000). Conclusions. When compared with a previous report from southern Sweden, the prevalence of RA seems not to have declined in the last decade. The proportion of patients with ongoing biological treatment was slightly higher in women than men. SHCR data are promising additions to other methods to gain frequency estimates of clinically important disease in a timely and cost-efficient manner.

  • Ingår i: Annals of the Rheumatic Diseases. - : BMJ. - 1468-2060 .- 0003-4967. ; 74:6, s. 1094-1101

    • OBJECTIVE: To estimate the incremental cost-effectiveness of infliximab versus conventional combination treatment over 21 months in patients with methotrexate-refractory early rheumatoid arthritis. METHODS: In this multicentre, two-arm, parallel, randomised, active-controlled, open-label trial, rheumatoid arthritis patients with <1 year symptom duration were recruited from 15 rheumatology clinics in Sweden between October 2002 and December 2005. After 3-4 months of methotrexate monotherapy, patients not achieving low disease activity were randomised to addition of infliximab or sulfasalazine+hydroxychloroquine (conventional treatment group). Costs of drugs, healthcare use, and productivity losses were retrieved from nationwide registers, while EuroQol 5-Dimensions utility was collected quarterly. RESULTS: Of 487 patients initially enrolled, 128 and 130 were randomised to infliximab and conventional treatment, respectively. The infliximab group accumulated higher drug and healthcare costs (€27 487 vs €10 364; adjusted mean difference €16 956 (95% CI 14 647 to 19 162)), while productivity losses did not differ (€33 804 vs €29 220; €3961 (95% CI -3986 to 11 850)), resulting in higher societal cost compared to the conventional group (€61 291 vs €39 584; €20 916 (95% CI 12 800 to 28 660)). Mean accumulated quality-adjusted life-years (QALYs) did not differ (1.10 vs 1.12; adjusted mean difference favouring infliximab treatment 0.01 (95% CI -0.07 to 0.08)). The incremental cost-effectiveness ratios for the infliximab versus conventional treatment strategy were €2 404 197/QALY from the societal perspective and €1 948 919/QALY from the healthcare perspective. CONCLUSIONS: In early, methotrexate-refractory rheumatoid arthritis, a treatment strategy commencing with addition of infliximab, as compared to sulfasalazine+hydroxychloroquine, was not cost-effective over 21 months at willingness to pay levels generally considered acceptable.

  • Biological vs Conventional Combination Treatment and Work Loss in Early Rheumatoid Arthritis A Randomized Trial

    • IMPORTANCE The introduction of biological tumor necrosis factor inhibitors has improved the treatment of rheumatoid arthritis (RA) but at a substantial cost. These drugs have been shown to lead to superior radiological outcomes compared with a combination of conventional disease-modifying antirheumatic drugs over 2 years. OBJECTIVE To investigate whether radiological superiority translates into better work loss outcomes. DESIGN, SETTING, AND PARTICIPANTS Multicenter, 2-arm, parallel, randomized, active-controlled, open-label trial. Patients with early RA (symptom duration <1 year) were recruited from 15 rheumatology clinics in Sweden from October 1, 2002, through December 31, 2005. The study population was restricted to working-age patients (aged <63 years). INTERVENTIONS Patients who did not achieve low disease activity after 3 to 4 months of methotrexate therapy were randomized to receive additional biological treatment with infliximab or conventional combination treatment with sulfasalazine plus hydroxychloroquine. MAIN OUTCOMES AND MEASURES Monthly sick leave and disability pension days 21 months after randomization retrieved from the nationwide Swedish Social Insurance Office register. Main analyses were by intention to treat, including all patients, and adjusted for baseline sick leave and disability pension. RESULTS Of 204 eligible patients, 105 were randomized to biological and 99 to conventional treatment. Seven patients in the biological and 4 in the conventional treatment group never received the study drug, and 72 and 52 patients, respectively, followed the study per protocol for 21 months. The baseline mean (SD) work loss was 17 (13) d/mo (median, 16 d/mo) in both groups (mean difference, 0.6 d/mo; 95% CI, -3.0 to 3.9). The mean changes in work loss at 21 months were -4.9 d/mo in the biological and -6.2 d/mo in the conventional treatment group (adjusted mean difference, 1.6 d/mo; 95% CI, -1.2 to 4.4). Including only patients receiving at least 1 dose of assigned treatment, the adjusted mean difference was 1.5 d/mo (95% CI, -1.5 to 4.4), and in per-protocol analysis the adjusted mean difference was 0.3 d/mo (95% CI, -2.8 to 3.8). CONCLUSIONS AND RELEVANCE The radiological superiority of biological compared with conventional combination therapy did not translate into better work loss outcomes in patients with early RA who had experienced an insufficient response to methotrexate.

    • Objective To compare long-term work loss in methotrexate-refractory early rheumatoid arthritis (RA) randomized to addition of infliximab or conventional combination treatment. Methods Multicentre, two-arm, parallel, randomized, active-controlled, open-label trial. RA patients with <1y symptom duration were recruited from 15 rheumatology clinics in Sweden between 2002-2005. Patients who did not achieve low disease activity after 3-4 months methotrexate therapy were randomized to addition of infliximab or conventional combination treatment with sulfasalazine+hydroxychloroquine. Yearly sick leave and disability pension days over 7 years after randomization were retrieved from nationwide registers kept by the Swedish Social Insurance Agency. Results Of 210 working age patients, 109 were randomized to infliximab (mean age=48.4y, 73% women) and 101 to conventional treatment (48.7y, 77%). The year before randomization the mean number of annual work days lost was 127 in the infliximab arm and 118 in the conventional treatment group (mean difference, 9; 95%CI, -23 to 39). Compared to the year before randomization, the mean changes at 7 years were -25 days in the infliximab and -26 days in the conventional treatment group (adjusted mean difference, 10; 95%CI, -25 to 46). The mean cumulative work loss days was 846 in the infliximab group and 701 in the conventional treatment group (adjusted mean difference, 104; 95%CI, -56 to 284). Conclusions Long-term work loss improved significantly in early RA randomized to infliximab+methotrexate or conventional combination therapy. No difference was detected between strategies, and the level of work loss days remained twice that observed in the general population.TRIAL REGISTRATION NUMBER: NCT00764725 This article is protected by copyright.

  • Gas-induced restructuring of palladium model catalysts studied with atomic force microscopy

    • The structure of thin Pd films evaporated onto planar SiO2 substrates changes dramatically during oxygen/hydrogen exposures in ultrahigh vacuum. In this work we have used an atomic force microscope(AFM), operated in the attractive mode, to obtain the three‐dimensional morphology of the Pd surface for different film thicknesses and treatments, and compared the data with transmission electron microscopy(TEM) micrographs. During restructuring, a 100‐Å film changes from being a smooth continuous film with cracks into metal clusters dispersed on the SiO2 support. In the 5‐Å case the metal films are already well dispersed as fabricated. Here the gas exposure instead results in a clustering effect resulting in larger particles. The AFM gives results which are consistent with TEM micrographs but also gives additional information on metal particle shape which can lead to a further understanding of the restructuring process.
