Presence of anti-citrullinated protein antibodies and costs and disease activity in early rheumatoid arthritis - a 3-year follow-up.

Objective: To analyse healthcare utilization, loss of productivity, and disease activity in relation to presence of anti-citrullinated protein antibodies (ACPAs). Method: In total, 447 ACPA-positive and 224 ACPA-negative patients from two early rheumatoid arthritis cohorts, recruited 1996-1998 (cohort 1) and 2006-2009 (cohort 2), were followed during 3 years. Data on disease activity were collected, and patients reported healthcare utilization and days lost from work. Disease activity, healthcare costs, and loss of productivity were compared between ACPA groups. Linear regression was performed, controlling for confounders. Results: Healthcare costs did not differ significantly by ACPA status (EUR 3214 for vs EUR 2174 for ACPA-positive vs ACPA-negative patients in cohort 1, ns; EUR 4150 vs EUR 3820 in cohort 2, ns). Corresponding values for loss of productivity were EUR 9148 vs EUR 7916 (ns) and EUR 5857 vs EUR 5995 (ns). Total prescription of traditional disease-modifying anti-rheumatic drugs was higher in cohort 2 than in cohort 1. Methotrexate prescription was higher in ACPA-positive patients, but biologics did not differ significantly between ACPA groups. Disease activity was significantly more improved in cohort 2, but there was no difference in achieving remission in relation to ACPA status. In cohort 1, 25% of ACPA-positive patients were in remission vs 31% of ACPA-negative (ns) and in cohort 2, 55% vs 60% (ns). Conclusions: With increasing drug treatment for both ACPA-positive and ACPA-negative patients, outcome in ACPA-positive was no more severe than in ACPA-negative patients. Healthcare costs and loss of productivity were similar in the two groups.

Costs and disease activity in early rheumatoid arthritis in 1996-2000 and 2006-2011, improved outcome and shift in distribution of costs: a two-year follow-up.

OBJECTIVE: To evaluate changes in healthcare utilization, costs, and disease activity from 1996 to 2011 for patients with early rheumatoid arthritis (RA). METHOD: Two cohorts of patients with early RA, included in 1996-1998 (T1) and 2006-2009 (T2), were followed regularly. Healthcare utilization, costs, and disease activity were compared between cohorts during 2 years after diagnosis. RESULTS: Disease activity was significantly improved in T2 vs T1. Drug costs increased in T2 vs T1 (EUR 911 vs EUR 535, respectively; p = 0.017), and costs for RA-related hospitalization decreased. More than 90% in T2 were prescribed disease-modifying anti-rheumatic drugs (DMARDs) at inclusion compared to 50% in T1. At 2 year follow-up, levels were still > 90% in T2, while corresponding values in T1 were just above 70%. Comparing T2 to T1, total direct costs were slightly higher in T2 (EUR 3941 vs EUR 3364, respectively; ns), sick leave decreased (EUR 3511 vs EUR 5672; p = 0.025), while disability pension increased slightly (EUR 4889 vs EUR 4244; ns), but total indirect costs remained unchanged (EUR 8400 vs EUR 9916; ns). Total direct and indirect costs did not differ between the cohorts (EUR 12 342 in T2 vs EUR 13 280 in T1; ns), and loss of productivity still represented the largest component of total costs. CONCLUSION: T2 patients were prescribed DMARDs earlier and more aggressively than T1 patients. Stable and better improvements in disease activity, function, and quality of life were achieved in T2 compared to T1. There was a shift within the components in direct costs and indirect costs, but total costs remained essentially unchanged.

Rheumatoid arthritis is still expensive in the new decade: a comparison between two early RA cohorts, diagnosed 1996-98 and 2006-09.

OBJECTIVES: To calculate total costs during the first year after diagnosis in 463 patients with early rheumatoid arthritis (RA) included during 2006-09 (T2) and compare the results with a similar cohort included in 1996-98 (T1). METHOD: Clinical and laboratory data were collected regularly in both cohorts, and patients completed biannual questionnaires reporting health care utilization and number of days lost from work. RESULTS: Disease activity was similar in both cohorts T1 and T2 at inclusion. Significant improvements were seen during the first year in both cohorts but were more pronounced in T2. Outpatient care increased and hospitalization decreased in T2 compared with T1. Almost 3% of patients had surgery in both cohorts, but in T2, only women had surgery. Drug costs were higher in T2 than in T1 (EUR 689 vs. EUR 435). In T2, 12% of drug costs were direct costs and 4% were total costs. The corresponding values for T1 were 9% and 3%. In T1, 50% were prescribed disease-modifying anti-rheumatic drugs (DMARDs) at inclusion, compared to T2, where prescription was > 90%. Direct costs were EUR 5716 in T2 and EUR 4674 in T1. Costs for sick leave were lower in T2 than in T1 (EUR 5490 vs. EUR 9055) but disability pensions were higher (EUR 4152 vs. EUR 2139), resulting in unchanged total costs. In T1, direct costs comprised 29% and indirect costs 71% of the total costs. The corresponding values for T2 were 37% and 63%. CONCLUSIONS: The earlier and more aggressive treatment of RA with traditional DMARDs in T2 resulted in better outcomes compared to T1. Direct costs were higher in T2, partly offset by decreased sick leave, but total costs remained unchanged.

Changes in sociodemographic characteristics at baseline in two Swedish cohorts of patients with early rheumatoid arthritis diagnosed 1996-98 and 2006-09.

OBJECTIVES: To compare baseline sociodemographic characteristics in two rheumatoid arthritis (RA) cohorts enrolled 10 years apart, and to examine differences with respect to the general population. METHOD: Clinical and sociodemographic data were collected in 320 early RA patients during 1996-98 (TIRA-1) and 467 patients in 2006-09 (TIRA-2). Multivariate logistic regression tests were performed and intercohort comparisons were related to general population data, obtained from official databases. RESULTS: TIRA-2 patients were older than TIRA-1 (58 vs. 56 years). Women (both cohorts, 67%) were younger than men in TIRA-1 (55 vs. 59 years) and in TIRA-2 (57 vs. 61 years). Disease activity was similar but TIRA-2 women scored worse pain and worse on the HAQ. Approximately 73% were cohabiting, in both cohorts and in the general population. Education was higher in TIRA-2 than in TIRA-2 but still lower than in the general population. Women had consistently higher education than men. Education was associated with age, younger patients having higher education. In both cohorts, lower education was associated with increased disability pension and increased sick leave. Sick leave was lower in TIRA-2 than in TIRA-1 (37% vs. 50%) but disability pension was higher (16% vs. 10%). In TIRA-1, 9% of women had disability pension compared with 17% in TIRA-2. A similar decrease in sick leave and an increase in disability pension were also seen in the general population. Older age and a higher HAQ score were associated with increased sick leave and being in the TIRA-2 cohort was associated with decreased sick leave. CONCLUSIONS: TIRA-2 patients were slightly older, better educated, had lower sick leave and higher disability pension than those in TIRA-1. Similar changes were seen simultaneously in the general population. Belonging to the TIRA-2 cohort was associated with decreased sick leave, indicating that societal changes are of importance.

Early rheumatoid arthritis 6 years after diagnosis is still associated with high direct costs and increasing loss of productivity: the Swedish TIRA project.

OBJECTIVES: To calculate total costs over 6 years after diagnosis of early rheumatoid arthritis (RA). METHOD: In the longitudinal prospective multicentre TIRA study, 239 patients from seven units, diagnosed in 1996-98, reported regularly on health-care utilization and the number of days lost from work. Costs were obtained from official databases and calculated using unit costs (Swedish kronor, SEK) from 2001. Indirect costs were calculated using the human capital approach (HCA). Costs were inflation adjusted to Euro June 2012, using the Swedish Consumer Price Index and the exchange rate of June 2012. Statistical analyses were based on linear mixed models (LMMs) for changes over time. RESULTS: The mean total cost per patient was EUR 14,768 in year 1, increasing to EUR 18,438 in year 6. Outpatient visits and hospitalization decreased but costs for surgery increased from EUR 92/patient in year 1 to EUR 444/patient in year 6. Drug costs increased from EUR 429/patient to EUR 2214/patient, mainly because of the introduction of biologics. In year 1, drugs made up for 10% of direct costs, and increased to 49% in year 6. Sick leave decreased during the first years but disability pensions increased, resulting in unchanged indirect costs. Over the following years, disability pensions increased further and indirect costs increased from EUR 10,284 in year 1 to EUR 13,874 in year 6. LMM analyses showed that indirect costs were unchanged whereas direct costs, after an initial fall, increased over the following years, leading to increasing total costs. CONCLUSIONS: In the 6 years after diagnosis of early RA, drug costs were partially offset by decreasing outpatient visits but indirect costs remained unchanged and total costs increased.

Costs and course of disease and function in early rheumatoid arthritis: a 3-year follow-up (the Swedish TIRA project).

OBJECTIVE: To calculate direct and indirect costs and to study disease activity and functional ability over 3 yr in early rheumatoid arthritis (RA). METHODS: Three hundred and three patients with early (< or = 1 yr) RA were recruited during a period of 27 months (1996-1998). Data were recorded during 3 yr to assess disease activity, functional ability, medication, health-care utilization and days lost from work. RESULTS: Within 3 months, improvements were seen regarding all recorded variables assessing disease activity and functional ability, but 15% had sustained high or moderate disease activity throughout the study period. Indirect costs exceeded direct costs in all 3 yr. The average direct costs were 3704 Euros (3297 US Dollars) in year 1 and 2652 Euros ( 2360 US Dollars ) in year 3. All costs decreased, except those for medication and surgery. Compared with men, women had more ambulatory care visits and used more complementary medicine. The indirect costs were 8871 Euros ( 7895 US Dollars) in year 1 and remained essentially unchanged; this was similar for both sexes. Almost 50% were on sick leave or early retirement at inclusion. Sick leave decreased but was offset by an increase in early retirement. The 14 patients who eventually received TNF inhibitors incurred higher costs even before prescription of anti-TNF therapy. CONCLUSION: Disease activity and functional ability improved within 3 months after diagnosis of early RA. Direct costs decreased, except for medication and surgery. Indirect costs remained unchanged. Fifteen per cent of the patients had high or moderate disease activity in all 3 yr, indicating a need for more aggressive early anti-rheumatic therapy.

Rheumatoid arthritis is already expensive during the first year of the disease (the Swedish TIRA project).

OBJECTIVE: To calculate direct and indirect costs in early rheumatoid arthritis (RA) and to characterize patients generating high and low costs respectively. METHODS: Two hundred and ninety-seven patients with recent-onset (< or = 12 months) RA were recruited. Clinical/laboratory data and 'health assessment questionnaire' (HAQ) were registered at inclusion and after 3, 6 and 12 months. After 6 and 12 months, the patients completed a questionnaire concerning health-care utilization and days lost from work. A cut-off point for direct costs was set at 34,000 Swedish kronor (euro3675) defining one-third of the patients as a high-cost group and two-thirds as low-cost group. Indirect costs were calculated for patients aged <65 yr. RESULTS: Two hundred and eleven patients completed the HAQ on both occasions. Indirect costs exceeded direct costs by a factor of 2.3. Sixty three per cent experienced work disability during the first year and were identified as the 'high-indirect-cost group'. Indirect costs accounted for >70% of total costs. Direct costs included ambulatory health care (76%), hospitalization (12%) and medication (9%). Men aged > or = 65 yr had low costs compared with younger men and women of all ages. In multiple logistic regression tests, HAQ, high levels of IgM rheumatoid factor (IgM RF) and poor hand function increased the odds of entering the high-direct-cost group, and poor hand function and pain increased the odds of entering the high-indirect-cost group. CONCLUSIONS: Substantial costs were incurred during the first year after diagnosis of early RA, mainly due to work disability. Indirect costs were two to three times higher than direct costs. High levels of IgM RF, high HAQ score, poor hand function and pain increased the odds of entering high-cost groups.

Socioeconomic costs of rheumatic diseases. Implications for technology assessment.

OBJECTIVES: To study the socioeconomic impact of rheumatic illness in Sweden and to discuss the consequences for technology assessment studies. METHODS: A cost-of-illness study based on data from official statistics and treatment studies. RESULTS: The total socioeconomic cost was 52 billion Swedish kronor (SEK) in 1994. The imbalance between direct (10% of total) and indirect costs (90 effectiveness of the healthcare sector, the need for new treatment methods, appropriate information systems, and technology assessment studies as well as the institutional arrangements for rehabilitation and basic medical research. CONCLUSIONS: A discussion of solutions for financial cooperation between county councils and regional social insurance offices should be considered. The new biotechnological pharmaceuticals will increase the cost for drugs in health care about 20 times, but the total socioeconomic cost for society may remain at the same level due to a decrease of inpatient costs and indirect costs for loss of production as well as a decrease of transfer payments from social insurance. It is unavoidable that the new pharmaceuticals require priority discussions and active resource allocation in health care and in other sectors of society.

Sacrococcygeal teratoma in Sweden between 1978 and 1989: long-term functional results.

Thirty-four patients operated with sacrococcygeal teratoma in Sweden between 1978 and 1989 were reviewed. Twenty-five children were available for functional follow-up. The patients and their parents were interviewed for bowel and micturition habits. Fourteen patients from this number were subjected to anorectal manometry (56%). Fifteen children reported normal bowel habits (60%). In 10 patients (40%) soiling was observed. However, four of them were under 3 years of age and wearing diapers, which made the functional evaluation difficult. The manometries showed normal and resting tone and squeezing pressures in 10 patients and subnormal values in four patients who also had soiling problems. All investigated children showed normal rectoanal inhibition reflex. Twenty-one patients reported normal micturition, in four (16%) urinary incontinence was recorded. Two of the latter children required intermittent clean catheterization, one was on medication and the last one lives without any treatment. No difference in functional outcome was noted between patients with intrapelvic or extrapelvic tumor location. Retrospectively, it is not possible to know whether the observed functional outcome is due to tumor growth or the result of surgery. Preoperative clinical investigation and in some cases anorectal manometry and cystometry could theoretically resolve this problem.
