Disability outcomes and dose escalation with etanercept, adalimumab, and infliximab in rheumatoid arthritis patients: a US-based retrospective comparative effectiveness study
[ PUBLICATION ]
INTRODUCTION: Rheumatoid arthritis (RA) is a chronic disease that if left untreated may substantially impair physical functioning. Etanercept, infliximab, and adalimumab are tumor necrosis factor (TNF) blockers whose FDA-approved indications in the US include moderate to severe RA. TNF-blocker dose escalation has been well documented in the literature; however, the comparative effectiveness of these agents remains uncertain.
OBJECTIVE: To compare the effectiveness and dose escalation ...

OBJECTIVE: The number of individuals ages >or=100 years in the US is expected to increase considerably in the future along with the need for arthroplasties. This report focuses on the poorly studied epidemiology and mortality outcomes of arthroplasty among these individuals.
METHODS: We describe the epidemiology of knee and hip arthroplasties among centenarians using data from a large hospital discharge database in the US (the Nationwide Inpatient Sample) during the period 1993 through ...

CONTEXT: Hydroxychloroquine, a commonly used antirheumatic medication, has hypoglycemic effects and may reduce the risk of diabetes mellitus.
OBJECTIVE: To determine the association between hydroxychloroquine use and the incidence of self-reported diabetes in a cohort of patients with rheumatoid arthritis.
DESIGN, SETTING, AND PATIENTS: A prospective, multicenter observational study of 4905 adults with rheumatoid arthritis (1808 had taken hydroxychloroquine and 3097 had never taken ...

CONTEXT: Abundant evidence links overweight and obesity with impaired health. However, controversies persist as to whether overweight and obesity have additional impact on cardiovascular outcomes independent of their strong associations with established coronary risk factors, eg, high blood pressure and high cholesterol level.
OBJECTIVE: To assess the relation of midlife body mass index with morbidity and mortality outcomes in older age among individuals without and with other major risk ...

PROMIS measures of pain, fatigue, negative affect, physical function, and social function demonstrated clinical validity across a range of chronic conditions
[ PUBLICATION ]
OBJECTIVE: To present an overview of a series of studies in which the clinical validity of the National Institutes of Health's Patient Reported Outcome Measurement Information System (NIH; PROMIS) measures was evaluated, by domain, across six clinical populations.
STUDY DESIGN AND SETTING: Approximately 1,500 individuals at baseline and 1,300 at follow-up completed PROMIS measures. The analyses reported in this issue were conducted post hoc, pooling data across six previous studies, and ...

Proteomic analysis of secreted proteins in early rheumatoid arthritis: anti-citrulline autoreactivity is associated with up regulation of proinflammatory cytokines
[ PUBLICATION ]
OBJECTIVES: To identify peripheral blood autoantibody and cytokine profiles that characterise clinically relevant subgroups of patients with early rheumatoid arthritis using arthritis antigen microarrays and a multiplex cytokine assay.
METHODS: Serum samples from 56 patients with a diagnosis of rheumatoid arthritis of <6 months' duration were tested. Cytokine profiles were also determined in samples from patients with psoriatic arthritis (PsA) and ankylosing spondylitis (n = 21), and ...

OBJECTIVE: To develop and validate a self- or parent-administered instrument for measuring functional status in children with juvenile rheumatoid arthritis (JRA).
METHODS: We adapted the Stanford Health Assessment Questionnaire (HAQ) for use in children ages 1-19 years, by adding several new questions, such that for each functional area, there was at least 1 question relevant to children of all ages. The face validity of the instrument was evaluated by a group of 20 health professionals ...

Improved responsiveness and reduced sample size requirements of PROMIS physical function scales with item response theory
[ PUBLICATION ]
INTRODUCTION: The Health Assessment Questionnaire Disability Index (HAQ) and the SF-36 PF-10, among other instruments, yield sensitive and valid Disability (Physical Function) endpoints. Modern techniques, such as Item Response Theory (IRT), now enable development of more precise instruments using improved items. The NIH Patient Reported Outcomes Measurement Information System (PROMIS) is charged with developing improved IRT-based tools. We compared the ability to detect change in ...

A canadian study of the total medical costs for patients with systemic lupus erythematosus and the predictors of costs
[ PUBLICATION ]
OBJECTIVE: We conducted a cost identification analysis on 164 consecutive patients with systemic lupus erythematosus (SLE) who entered the Montreal General Hospital Lupus Registry between January 1977 and January 1990, compared their costs to the population of Quebec, and determined the predictors of cost.
METHODS: In January 1990 and 1991, participants completed questionnaires on health services utilization and on employment history over the preceding 6 months, as well as on functional, ...

BACKGROUND: Persons with lower health risks tend to live longer than those with higher health risks, but there has been concern that greater longevity may bring with it greater disability. We performed a longitudinal study to determine whether persons with lower potentially modifiable health risks have more or less cumulative disability.
METHODS: We studied 1741 university alumni who were surveyed first in 1962 (average age, 43 years) and then annually starting in 1986. Strata of high, ...

The Patient-Reported Outcomes Measurement Information System (PROMIS) developed and tested its first wave of adult self-reported health outcome item banks: 2005–2008
[ PUBLICATION ]
OBJECTIVES: Patient-reported outcomes (PROs) are essential when evaluating many new treatments in health care; yet, current measures have been limited by a lack of precision, standardization, and comparability of scores across studies and diseases. The Patient-Reported Outcomes Measurement Information System (PROMIS) provides item banks that offer the potential for efficient (minimizes item number without compromising reliability), flexible (enables optional use of interchangeable ...

BACKGROUND: Health care costs are generally highest in the year before death, and much attention has been directed toward reducing costs for end-of-life care. However, it is unknown whether cardiovascular risk profile earlier in life influences health care costs in the last year of life. This study addresses this question.
METHODS: Prospective cohort of adults from the Chicago Heart Association Detection Project in Industry included 6582 participants (40% women), aged 33 to 64 years at ...

Progress in assessing physical function in arthritis: PROMIS short forms and computerized adaptive testing.
[ PUBLICATION ]
OBJECTIVE: Assessing self-reported physical function/disability with the Health Assessment Questionnaire Disability Index (HAQ) and other instruments has become central in arthritis research. Item response theory (IRT) and computerized adaptive testing (CAT) techniques can increase reliability and statistical power. IRT-based instruments can improve measurement precision substantially over a wider range of disease severity. These modern methods were applied and the magnitude of ...
