Kim HW, Lee YJ, Ha YJ, Lee EB, Lee YJ, Kang EH. Impact of socioeconomic status on biologics utilization in rheumatoid arthritis: revealing inequalities and healthcare efficiency. Korean J Intern Med 2024; 39:668-679. [PMID: 38419335 PMCID: PMC11236806 DOI: 10.3904/kjim.2023.276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 10/06/2023] [Accepted: 10/30/2023] [Indexed: 03/02/2024] Open
Abstract
BACKGROUND/AIMS This cross-sectional study aimed to investigate biologics treatment disparities in rheumatoid arthritis (RA) patients based on socioeconomic status (SES). METHODS Data from the KOrean Observational Study Network for Arthritis (KORONA) database were analyzed to assess various factors associated with SES, health behaviors, and biologics use. Logistic regression and structured equation modeling (SEM) were utilized for data analysis. RESULTS Among 5,077 RA patients included, 393 (7.7%) patients were identified as biologics users. Within the entire cohort, 31.8% of the participants were in the low-income and low-education groups, and 39.3% of the participants were in the high-income and high-education groups. Despite the patients with low income or low education experienced higher disease activity at diagnosis, had more comorbidities, exhibited higher medication compliance, underwent more check-ups, and had more hospital admissions than their counterparts, the odds of patients with low-income receiving biologics were 34% lower (adjusted odds ratio = 0.76, 95% confidence interval: 0.60-0.96, p = 0.021) after adjustment for demographics and comorbidities. SEM and pathway analyses confirmed the negative impact of low SES on biologics use. CONCLUSION The findings suggest that SES plays a significant role in biologics use among RA patients, indicating potential healthcare inefficiencies for low SES patients. Moreover, adverse healthcare habits negatively affect biologics use in RA patients. The study highlights the importance of considering socioeconomic factors while discussing biologics use and promoting equitable access to biologics for optimal RA management.

Understanding the psychosocial determinants of effective disease management in rheumatoid arthritis to prevent persistently active disease: a qualitative study. RMD Open 2024; 10:e004104. [PMID: 38609321 PMCID: PMC11029421 DOI: 10.1136/rmdopen-2024-004104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Accepted: 03/25/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND According to epidemiological studies, psychosocial factors are known to be associated with disease activity, physical activity, pain, functioning, treatment help-seeking, treatment waiting times and mortality in people with rheumatoid arthritis (RA). Limited qualitative inquiry into the psychosocial factors that add to RA disease burden and potential synergistic interactions with biological parameters makes it difficult to understand patients' perspectives from the existing literature. AIM This study aimed to gather in-depth patient perspectives on psychosocial determinants that drive persistently active disease in RA, to help guide optimal patient care. METHODS Patient research partners collaborated on the research design and materials. Semistructured interviews and focus groups were conducted online (in 2021) with patients purposively sampled from diverse ethnicities, primary languages, employment status and occupations. Data were analysed using inductive thematic analysis. RESULTS 45 patients participated across 28 semistructured interviews and three focus groups. Six main themes on psychosocial determinants that may impact RA management were identified: (1) healthcare systems experiences, (2) patient education and health literacy, (3) employment and working conditions, (4) social and familial support, (5) socioeconomic (dis)advantages, and (6) life experiences and well-being practices. CONCLUSION This study emphasises the importance of clinicians working closely with patients and taking a holistic approach to care that incorporates psychosocial factors into assessments, treatment plans and resources. There is an unmet need to understand the relationships between interconnected biopsychosocial factors, and how these may impact on RA management.

[PMID: 38238799 PMCID: PMC10797737 DOI: 10.1186/s41927-023-00371-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 12/23/2023] [Indexed: 01/22/2024] Open
Abstract
BACKGROUND This study aimed to assess the association between social factors, demographic parameters, and disease activity among rheumatoid arthritis (RA) patients. METHODS The University of Pittsburgh Rheumatoid Arthritis Comparative Effectiveness Research (RACER) registry was used for this study and included patients meeting 1987 ACR criteria for RA enrolled between 2010-2015. The registry collected clinical and laboratory data at each visit, permitting the calculation of disease activity measures that included Disease Activity 28-C Reactive Protein (DAS28-CRP). The current study was conducted as a cross-sectional study in which baseline data were used to construct multiple logistic regression models assessing the relationship between disease activity measures (DAS28-CRP), functional capacity (health assessment questionnaire (HAQ)), selected demographic and social factors (occupation, education, income, marital status, race, gender, age, and BMI), and clinical/laboratory variables. RESULTS The analyses included 729 patients with baseline DAS28-CRP and social/demographic data. The mean age at enrollment was 59.5 (Standard Deviation (SD) = 12.7) years, 78% were female, and the median RA disease duration was 9.8 (Interquartile Range (IQR): 3.7, 19.1) years. We dichotomized the DAS28-CRP score and defined scores above or below 3.1 as high versus low RA disease activity. Most patients with high RA disease activity (N = 326, 45%) had less than a college degree (70%), were not working/retired/disabled (71%), and had an annual income under $50 K (55%). We found that higher body mass index (BMI) (Odds Ratio (OR) = 1.04, 95% CI: 1.01-1.08), longer disease duration (> 2 and < 10 years versus ≤ 2 years of disease) (OR = 0.45, 95% CI: 0.25-0.78), and being retired (OR = 1.74, 95% CI: 1.02-2.98) were associated with RA disease activity. CONCLUSION Increased RA activity may be associated with various social factors, potentially leading to more severe and debilitating disease outcomes. These findings provide evidence to support efforts to monitor disparities and achieve health equity in RA.

Abstract
OBJECTIVE Social determinants of health (SDoH), such as poverty, are associated with increased burden and severity of rheumatic and musculoskeletal diseases. This study was undertaken to study the prevalence and documentation of SDoH-related needs in electronic health records (EHRs) of individuals with these conditions. METHODS We randomly selected individuals with ≥1 International Classification of Diseases, Ninth/Tenth Revision (ICD-9/10) code for a rheumatic/musculoskeletal condition enrolled in a multihospital integrated care management program that coordinates care for medically and/or psychosocially complex individuals. We assessed SDoH documentation using terms for financial needs, food insecurity, housing instability, transportation, and medication access according to EHR note review and ICD-10 SDoH billing codes (Z codes). We used multivariable logistic regression to examine associations between demographic factors (age, gender, race, ethnicity, insurance) and ≥1 (versus 0) SDoH need as the odds ratio (OR) with 95% confidence interval (95% CI). RESULTS Among 558 individuals with rheumatic/musculoskeletal conditions, 249 (45%) had ≥1 SDoH need documented in EHR notes by social workers, care coordinators, nurses, and physicians. A total of 171 individuals (31%) had financial insecurity, 105 (19%) had transportation needs, 94 (17%) had food insecurity; 5% had ≥1 related Z code. In the multivariable model, the odds of having ≥1 SDoH need was 2.45 times higher (95% CI 1.17-5.11) for Black versus White individuals and significantly higher for Medicaid or Medicare beneficiaries versus commercially insured individuals. CONCLUSION Nearly half of this sample of complex care management patients with rheumatic/musculoskeletal conditions had SDoH documented within EHR notes; financial insecurity was the most prevalent. Only 5% of patients had representative billing codes suggesting that systematic strategies to extract SDoH from notes are needed.

ACR Open Rheumatol 2023; 5:694-700. [PMID: 37872884 PMCID: PMC10716804 DOI: 10.1002/acr2.11625] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 09/29/2023] [Accepted: 10/05/2023] [Indexed: 10/25/2023] Open
Abstract
OBJECTIVE Older adults with rheumatoid arthritis (RA) account for up to one-third of the RA population and are less likely to receive optimal treatment. For the subgroup of older adults with late-onset RA (LORA), who experience more symptomatic and progressive disease, suboptimal treatment could be more consequential than the general population who age with RA. We evaluated use of disease-modifying antirheumatic drugs (DMARDs) in older adults with a new diagnosis of LORA. METHODS In this retrospective observational study, we identified adults 66 years of age or older with a new diagnosis of LORA using Medicare data from 2008 to 2017. Information on baseline patient characteristics and DMARD initiation during the first 12 months after LORA diagnosis were collected. We also assessed concomitant use of glucocorticoids (GCs). RESULTS We identified 33,373 older adults with new diagnosis of LORA. Average age at LORA diagnosis was 76.7 (SD 7.6); 75.4% were female, 76.9% were White, and 35.6% had low-income subsidy (LIS). Less than one-third were initiated on a DMARD (28.9%). In multivariable analyses, DMARD initiation was associated with younger age, fewer comorbidities, and absence of LIS status. Concomitant long-term (>3 months) GC use was higher among those on any DMARD (44.3%) compared with those without (15.2%). CONCLUSIONS DMARD initiation after new diagnosis of LORA is low despite current clinical practice guidelines recommending early aggressive initiation of treatment. Long-term GC use is common among those on any DMARDs, raising concern for suboptimal DMARD use. Further studies are needed to understand drivers of DMARD use in older adults.

Abstract
OBJECTIVE To examine influences of sociocultural and economic determinants on physical therapy (PT) utilization for older adults with rheumatoid arthritis (RA). METHODS In these annual cross-sectional analyses between 2012 and 2016, we accessed Medicare enrollment data and fee-for-service claims. The cohort included Medicare beneficiaries with RA based on 3 diagnosis codes or 2 codes plus a disease-modifying antirheumatic drug medication claim. We defined race and ethnicity and dual Medicare/Medicaid coverage (proxy for income) using enrollment data. Adults with a Current Procedural Terminology code for PT evaluation were classified as utilizing PT services. Associations between race and ethnicity and dual coverage and PT utilization were estimated with logistic regression analyses. Potential interactions between race and ethnicity status and dual coverage were tested using interaction terms. RESULTS Of 106,470 adults with RA (75.1% female; aged 75.8 [SD 7.3] years; 83.9% identified as non-Hispanic White, 8.8% as non-Hispanic Black, 7.2% as Hispanic), 9.6-12.5% used PT in a given year. Non-Hispanic Black (adjusted odds ratio [aOR] 0.77, 95% CI 0.73-0.82) and Hispanic (aOR 0.92, 95% CI 0.87-0.98) individuals had lower odds of PT utilization than non-Hispanic White individuals. Adults with dual coverage (lower income) had lower odds of utilization than adults with Medicare only (aOR 0.44, 95% CI 0.43-0.46). There were no significant interactions between race and ethnicity status and dual coverage on utilization. CONCLUSION We found sociocultural and economic disparities in PT utilization in older adults with RA. We must identify and address the underlying factors that influence these disparities in order to mitigate them.

Abstract
BACKGROUND/AIMS To evaluate the role of early immunosuppressive therapy (IMT) in the management of rheumatoid arthritis (RA)-associated peripheral ulcerative keratitis (PUK). METHODS Single-centre, retrospective, comparative cohort study. Patients with RA-associated PUK were divided into two groups; those exposed to and those not exposed to early IMT, defined as administrating therapy within the first 4 weeks from the PUK onset. Outcomes included PUK recurrence, control of inflammation and development of ocular complications, including corneal scarring and perforation, cataract formation or progression and permanent visual loss. RESULTS A total of 52 eyes from 36 patients were included for analysis; 37 (71.2%) eyes received early IMT and 15 (28.8%) eyes did not. Follow-up time was 41.2+53.3 months (range: 4-236 months). While early IMT was a protective factor (HR 0.345, 95% CI 0.126 to 0.946, p=0.039), late RA diagnosis after PUK onset (HR 4.93, 95% CI 1.75 to 13.85, p=0.002) and retarded (≥2 months) control of inflammation (HR 8.37, 95% CI 1.88 to 37.16, p=0.005) were risk factors for PUK recurrence. Late IMT (OR 7.75, 95% CI 2.00 to 29.99, p=0.003), an unknown diagnosis of RA at first visit (OR 4.14, 95% CI 1.15 to 14.91, p=0.030) and at least one PUK recurrence (OR 6.42, 95% CI 1.71 to 24.07, p=0.006) were risk factors for visual loss. Survival analysis rendered eyes exposed to early IMT a lower risk of PUK recurrence (p=0.039). CONCLUSION Eyes with RA-associated PUK exposed to early IMT were more likely to achieve earlier inflammatory control, fewer recurrences and had better visual outcomes.

Abstract
OBJECTIVES To understand the relationships between deprivation and obesity with self-reported disability and disease activity in people with RA, and to determine whether BMI mediates the relationship between area-level deprivation and these outcomes. METHODS Data came from the Rheumatoid Arthritis Medication Study (RAMS), a 1-year multicentre prospective observational cohort of people with RA recruited from rheumatology centres across England commencing MTX for the first time. A total of 1529 and 1626 people were included who had a baseline and at least one follow-up measurement at 6 or 12 months of HAQ-Disability Index (HAQ-DI) and DAS in 28 joints (DAS28), respectively. Linear mixed models estimated the associations of deprivation and obesity with repeated measures HAQ-DI and DAS28. Causal mediation analyses estimated the mediating effect of BMI on the relationship between deprivation and RA outcomes. RESULTS Higher deprivation and obesity were associated with higher disability [adjusted regression coefficients highest vs lowest deprivation fifths 0.32 (95% CI 0.19, 0.45); obesity vs no obesity 0.13 (95% CI 0.06, 0.20)] and higher disease activity [adjusted regression coefficients highest vs lowest deprivation fifths 0.34 (95% CI 0.11, 0.58); obesity vs no obesity 0.17 (95% CI 0.04, 0.31)]. BMI mediated part of the association between higher deprivation and self-reported disability (14.24%) and DAS (17.26%). CONCLUSIONS People with RA living in deprived areas have a higher burden of disease, which is partly mediated through obesity. Weight-loss strategies in RA could be better targeted towards those living in deprived areas.

Abstract
OBJECTIVE To investigate how social support, financial status, and lifestyle influence the development of excess disability in rheumatoid arthritis (RA). METHODS Data were obtained from the Étude et Suivi des Polyarthrites Indifférenciées Récentes (ESPOIR) cohort study of people with RA. A previous analysis identified groups with similar inflammation trajectories but markedly different disability over 10 years; those in the higher disability trajectory groups were defined as having "excess disability." Self-reported data regarding contextual factors (social support, financial situation, lifestyle) were obtained from participants, and they completed patient-reported outcome measures (pain, fatigue, anxiety, depression) at baseline. The direct effect of the contextual factors on excess disability and the effect mediated by patient-reported outcome measures were assessed using structural equation models. Findings were validated in 2 independent data sets (Norfolk Arthritis Register [NOAR], Early Rheumatoid Arthritis Network [ERAN]). RESULTS Of 538 included ESPOIR participants (mean age ± SD 48.3 ± 12.2 years; 79.2% women), 200 participants (37.2%) were in the excess disability group. Less social support (β = 0.17 [95% confidence interval (95% CI) 0.08, 0.26]), worse financial situation (β = 0.24 [95% CI 0.14, 0.34]), less exercise (β = 0.17 [95% CI 0.09-0.25]), and less education (β = 0.15 [95% CI 0.06, 0.23]) were associated with excess disability group membership; smoking, alcohol consumption, and body mass index were not. Fatigue and depression mediated a small proportion of these effects. Similar results were seen in NOAR and ERAN. CONCLUSION Greater emphasis is needed on the economic and social contexts of individuals with RA at presentation; these factors might influence disability over the following decade.

Do it fast! Early access to specialized care improved long-term outcomes in rheumatoid arthritis: data from the REAL multicenter observational study. Adv Rheumatol 2023; 63:17.

Abstract
BACKGROUND Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. METHODS Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed "early" when the rheumatologist was the first or second physician consulted after symptoms onset, and "late" when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. RESULTS We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6-36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: -0.25 [-0.46, -0.04] and - 0.196 [-0.306, -0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. CONCLUSIONS Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.

[PMID: 36106932 PMCID: PMC10100498 DOI: 10.1002/acr.25024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 08/22/2022] [Accepted: 09/13/2022] [Indexed: 12/31/2022]
Abstract
OBJECTIVE Socioeconomic status (SES) influences disease outcomes in rheumatoid arthritis (RA) patients. Differences in medication use may partly explain this association. A scoping review was used to identify research conducted on this topic and determine what knowledge gaps remain. METHODS Medline, Embase, and PsychInfo were searched from their inception until February 2022 for studies that assessed SES and medication use as an outcome variable. Data was extracted on the use of specific SES measures, medication use, and whether differences in SES variables were associated with differences in medication use. RESULTS We identified 2,103 studies, of which 81 were selected for inclusion. Included studies originated most frequently from the US (42%); the mean ± SD age of participants was 55.9 ± 6.8 years, and most were female (75%). Studies measured a median of 4 SES variables (interquartile range 3-6), with educational, area-level SES, and income being the most frequent measurements used. Patients' race and/or ethnicity were documented by 34 studies. Studies primarily assessed the likelihood of prescription of disease-modifying antirheumatic drugs or dispensation, medication adherence, or treatment delays. A majority of studies documented at least 1 SES measure associated with a difference in medication use. CONCLUSION There is some evidence that SES affects use of medications in patients with RA; however, multiple definitions of SES have been utilized, making comparisons between studies difficult. Prospective studies with consistently defined SES will be needed to determine whether differences in medication use accounts for the poorer outcomes experienced by patients of lower SES.

Abstract
OBJECTIVE A randomized controlled trial [Joint Resources - Sedentary Behaviour (JR-SB) intervention] aimed to reduce sedentary behaviour and increase light-intensity physical activity in patients with rheumatoid arthritis (RA) through motivational counselling and text messages. Since a large proportion of invited patients declined to participate, this study aims to compare sociodemographic, clinical, and lifestyle factors between included patients and patients declining to participate (non-participants) in the JR-SB study and to investigate which characteristics were associated with participation. METHOD A register-based cross-sectional study was conducted. All patients invited to participate in the JR-SB study were identified in the DANBIO registry, from which patients' clinical and lifestyle data were also retrieved. Data on sociodemography and comorbidity were extracted from national registers. Differences between participants and non-participants were determined by an independent t-test or a chi-squared test. Logistic regression analyses adjusted for various confounders tested the association of patient characteristics with the likelihood of participation in the JR-SB study. RESULTS A total of 467 (58%) declined participation in the JR-SB study. Non-participants were older and less educated, more were smokers, fewer performed regular physical activity, and more had comorbidity compared to participants. Regression analyses showed that a higher educational level and absence of comorbidity in particular were associated with participation in the JR-SB study. CONCLUSION Patients with RA who are less educated and with certain types of comorbidity are less motivated to participate in a physical activity intervention. The findings may inform the recruitment process and implementation of physical activity interventions in rheumatology clinical practice.

Abstract
OBJECTIVE Advances in treatment over the past 20 years have resulted in improved control of rheumatoid arthritis (RA). The objective of our study was to investigate whether there has been a decrease in permanent work disability associated with RA in the US. METHODS Medicare data from 1999 to 2015 were used to identify beneficiaries age 20-59 years with RA who became eligible for Medicare coverage under Social Security Disability Insurance. Diagnosis of RA was based on physician claims in the first year of enrollment. Annual rates of enrollment were sex- and age-standardized to the 2000 US population. RESULTS The study included 97,787 beneficiaries with RA and Social Security Disability Insurance across all years. Medicare enrollment was 26.0 per million in 1999 and 26.0 per million in 2015. Rates increased following the Great Recession of 2008-2009 before returning to prerecession levels. There was no linear trend over time after adjusting for the annual national unemployment rate (relative risk 0.99 per year [95% confidence interval 0.99-1.00]; P = 0.69). Risks of work disability were much higher among workers over age 50 years. CONCLUSION Based on Medicare enrollment by recipients of Social Security Disability Insurance, there was no decrease in permanent work disability among young and middle-age workers with RA in the US between 1999 and 2015.

Abstract
Background Rheumatoid arthritis (RA) can result in difficulties for mothers when undertaking daily care activities and increased psychological distress. However, few studies have examined how women with RA subjectively experience coping and wellbeing as part of their motherhood.
Methods Twenty mothers with a diagnosis of RA and a dependent child (18 years or younger) who were living in Australia took part in a semi-structured interview between June and November 2017. Purposive sampling was undertaken to include participants across degree of current RA severity, number and age of children, and having received a diagnosis before or after a first child to take account of variability across these experiences. A qualitative thematic analysis was conducted on the interview transcripts. Results The following themes were identified: ‘Burden and complexity in the mothering role’, ‘Losing control: Women’s experiences of distress’, and ‘Adjusting and letting go: Women’s experiences of wellbeing’. Experiences of distress, including feelings of failure, were associated with accounts of a loss of control over mothering practices among women, regardless of child age. In contrast, accounts of adjusting mothering practices and relinquishing control were associated with reports of enhanced wellbeing. In addition, some mothers reported greater ease due to increased independence of older children. The absence of social support exacerbated burden and distress in the women’s accounts, while the availability of support alleviated burden and was associated with reports of wellbeing. Conclusion Health professionals and services can provide support to mothers with RA by addressing feelings of failure, acknowledging strategies of adjustment and letting go, and encouraging access to social support.

Abstract
Across four studies, we investigated whether perceptions of children’s pain are influenced by their socioeconomic status (SES). We found evidence that children with low SES were believed to feel less pain than children with high SES (Study 1), and this effect was not moderated by child’s age (Study 2). Next, we examined life hardship as a mediator of this effect among children, finding that children with low SES were rated as having lived a harder life and thus as feeling less pain (Study 3). Finally, we examined downstream consequences for hypothetical treatment recommendations. We found that participants perceived children with low SES as less sensitive to pain and therefore as requiring less pain treatment than children with high SES (Study 4). Thus, we consistently observe that stereotypes of low-SES individuals as insensitive to pain may manifest in judgments of children and their recommended pain care. Implications of this work for theory and medical practice are discussed.

Abstract
BACKGROUND/OBJECTIVE A growing number of health systems have implemented eConsults to improve access to specialty advice, but few studies have described their use in rheumatology or impact on visit wait times. We evaluated the uptake of an eConsult program and its impact on wait times for in-person rheumatology visits. METHODS In this quality improvement project, we analyzed electronic health record data from 4 intervention clinics and 4 comparison clinics, 12 months before and after implementation of an eConsult program. We compared median wait time for rheumatology appointments using a pre-post difference-in-differences analysis and quantile regression, adjusting for patient age, race, sex, clinic pair, and primary insurance payer. We also interviewed 11 primary care providers from the intervention clinics and conducted a rheumatology provider focus group (n = 4) to elucidate experiences with the program. RESULTS Rheumatologists recommended management in primary care or referral to another specialty for 41% of eConsults, reducing initial demand for in-person visits. The median wait times dropped in the intervention and the comparison clinics (42 and 25 days, respectively). Intervention clinic median wait time dropped 17 days more than comparison clinics, and this was nonstatistically significant (p = 0.089). eConsults fit provider care tasks best for triage or initial workup for diagnosis, and less well when tests required interpretation, or when back and forth communication was needed to manage the patient's condition. CONCLUSIONS Implementation of eConsults for rheumatology was associated with reduced wait times for rheumatology appointments and supported primary care providers in the triage and workup for a substantial portion of patients.

Abstract
Physical and mental illnesses are driven by ethnicity, social, environmental and economic determinants. Novel theoretical frameworks in rheumatoid arthritis (RA) focus on links and adverse interactions between and within biological and social factors. This review aimed to summarise associations between socioeconomic status (SES) and RA disease activity, and implications for future research. Articles studying the association between SES and RA disease activity were identified, from 1946 until March 2021. The research question was: Is there an association between social deprivation and disease activity in people with RA? Articles meeting inclusion criteria were examined by one author, with 10% screened at abstract and full paper stage by a second author. Disagreements were resolved with input from a third reviewer. Information was extracted on definition/measure of SES, ethnicity, education, employment, comorbidities, disease activity and presence/absence of association between SES and disease activity. Initially, 1750 articles were identified, with 30 articles ultimately included. SES definition varied markedly-10 articles used a formal scale and most used educational attainment as a proxy. Most studies controlled for lifestyle factors including smoking and body mass index, and comorbidities. Twenty-five articles concluded an association between SES and RA disease activity; two were unclear; three found no association. We have demonstrated the association between low SES and worse RA outcomes. There is a need for further research into the mechanisms underpinning this, including application of mixed-methods methodology and consideration of syndemic frameworks to understand bio-bio and bio-social interactions, to examine disease drivers and outcomes holistically.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Abstract
The accumulation of amyloid plaques, or misfolded fragments of proteins, leads to the development of a condition known as amyloidosis, which is clinically recognized as a systemic disease. Amyloidosis plays a special role in the pathogenesis of neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease, and rheumatoid arthritis (RA). The occurrence of amyloidosis correlates with the aging process of the organism, and since nowadays, old age is determined by the comfort of functioning and the elimination of unpleasant disease symptoms in the elderly, exposure to this subject is justified. In Alzheimer's disease, amyloid plaques negatively affect glutaminergic and cholinergic transmission and loss of sympathetic protein, while in RA, amyloids stimulated by the activity of the immune system affect the degradation of the osteoarticular bond. The following monograph draws attention to the over-reactivity of the immune system in AD and RA, describes the functionality of the blood-brain barrier as an intermediary medium between RA and AD, and indicates the direction of research to date, focusing on determining the relationship and the cause-effect link between these disorders. The paper presents possible directions for the treatment of amyloidosis, with particular emphasis on innovative therapies.

Objectives: Use of biologics or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) is associated with infection in patients with rheumatoid arthritis (RA). Socioeconomic status is substantial in infectious diseases; however, the impact of socioeconomic status on risk for infection in patients with RA receiving b/tsDMARD remains unclear. Methods: We used the 2003-2017 Taiwanese National Health Insurance Research Database to identify patients with RA receiving b/tsDMARDs. A Cox regression analysis was used to estimate the associations of covariates with the risk of hospitalised infection shown as hazard ratios (HRs) with 95% confidence interval (CIs). Results: We identified 7,647 RA patients who started their first bDMARD/tsDMARD treatment. Log-rank analyses demonstrated the association between age (p < 0.001), urbanisation (p = 0.001), the insured amount (p = 0.021), and the hospitalisation. Cox proportional regression analyses showed that age was independently associated with hospitalised infection in a dose-response manner, whereas a high-income category had an inverse association (HR 0.48, 95% CI 0.23-0.96). Hospitalisation for infection within 5 years was a strong risk factor (HR 5.63, 95% CI 1.91-16.62), and living in a rural area tended to be a risk factor (HR 1.76, 95% CI 0.98-3.14) for incident hospitalised infection. Conclusions: This study showed the crucial impacts of age, socioeconomic status, and history of infection on hospitalised infection in patients with RA receiving b/tsDMARDs. These findings highlight the largely ignored role of socioeconomic status in risk stratification among patients receiving b/tsDMARDs for RA.

Abstract
OBJECTIVE The aim of this study was to evaluate referral and treatment delays by ethnicity/race in patients with rheumatoid arthritis (RA) treated at an academic rheumatology center. METHODS We reviewed the medical records of all RA patients evaluated at an outpatient clinic between 2011 and 2016 to identify newly diagnosed and naive-to-treatment patients. We determined the durations between symptom onset and first rheumatology visit and time to initiate treatment. Data extraction included referral source, demographics, treatment, and laboratory tests. Routine use of a multidimensional health assessment questionnaire allowed us to calculate baseline RAPID3 (routine assessment of patient index data 3) scores. Comparisons between self-reported ethnicity/race groups were performed. We used logistic regression models to analyze associations between baseline variables and early referral. RESULTS Data from 152 disease-modifying antirheumatic drug-naive RA patients were included in the study; 35% were white, 37% black, 20% Hispanic, and 8% other. The range in median time to first rheumatology visit was 6 to 8 months for all patient groups, except Hispanic. This group had a median time of 22.7 months (p = 0.01). The referral pattern was considerably variable between-groups; 40% of Hispanic patients were self-referred (p = 0.01). There were no statistically significant between-group differences for time to treatment initiation according to ethnicity/race. RAPID3 scores (p = 0.04) and erythrocyte sedimentation rates (p = 0.01) were significantly higher in the black and Hispanic groups. A high C-reactive protein value at baseline was associated with earlier referral. CONCLUSIONS There is significant delay in initial presentation to a rheumatologist that was associated with a higher disease severity at presentation, especially for Hispanic patients.

Abstract
RATIONALE The burden of rheumatoid arthritis (RA) and RA-associated interstitial lung disease (RA-ILD) in recent years has not been well characterized. OBJECTIVE In this study, we sought to describe RA and RA-ILD-related mortality rates and trends in the U.S. from 2005-2018, stratified by demographics. METHODS We used the Multiple Cause of Death Database available through the Centers for Disease Control and prevention website which contains data of all deceased U.S. residents. RA and RA-ILD-related deaths were identified using ICD-10 codes. We examined the age-adjusted mortality rates and trends stratified by demographics. RESULTS RA and RA-ILD-related mortality rates were higher in females and older age groups. However, the prevalence of ILD was higher in male decedents with RA compared to female decedents with RA (13.3% vs. 8.7%). RA-related mortality rates were the highest in Native Americans followed by Whites. Compared to Whites, Hispanics had lower RA-related mortality rates but higher RA-ILD-related mortality rates. Overall RA-related mortality rates per 1,000,000 population decreased from 30.6 in 2005 to 22.2 in 2018. RA-related mortality rates declined in both sex, all races, and all age groups. However, RA-ILD-related mortality rates remained stable in both sex, all races, and all age groups except for ages 65 to 84 years, in which the rates declined. CONCLUSIONS The overall RA-related mortality rates are decreasing, however, RA-ILD-related mortality rates remain stable except in age groups 65-84 years. This would suggest that therapies for RA and improvement in the management of other comorbidities have improved the overall outcomes in RA patients, but have had limited effect in the subgroup of patients with RA-ILD.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is an inflammatory autoimmune disease that causes chronic synovitis, resulting in progressive joint destruction and functional disability and affects approximately 400,000 people in the UK. This real-world study aimed to describe the characteristics, treatment patterns and clinical outcomes of patients who received abatacept in UK clinical practice. METHODS This was a multi-centre, retrospective, observational study of patients with RA treated with abatacept at four UK centres between 01 January 2013 and 31 December 2017. Data were collected from medical records of each patient from the index date (date of first bDMARD initiation) until the most recent visit, death or end of study (31 December 2017). RESULTS In total, 213 patients were included in the study. Patients received up to eight lines of therapy (LOTs). Treatment with abatacept, or any other bDMARD, was associated with reductions in DAS28-ESR and DAS28-CRP scores at 6 and 12 months. The distribution of EULAR responses (good/moderate/no response) tended to be more favourable for patients when receiving abatacept than when receiving other bDMARDs (22.8%/41.3%/35.9% versus 16.6%/41.4%/42.1% at 6 months, and 27.9%/36.1%/36.1% versus 21.2%/34.5%/44.2% at 12 months). Patients receiving abatacept at LOT1 (n = 68) spent significantly longer on treatment compared with patients receiving other bDMARDs (53.4 vs. 17.4 months; p< 0.01); a similar trend was observed for LOT2. Among patients who discontinued after 6 months, a greater proportion experienced infection requiring antibiotics when receiving other bDMARDs compared to those receiving abatacept. CONCLUSIONS RA patients who received bDMARDs, including abatacept, experienced reduced disease activity. When receiving abatacept as first or second line of therapy, patients persisted with treatment significantly longer than those receiving other bDMARDs.

Effect of disease duration and other characteristics on efficacy outcomes in clinical trials of tocilizumab for rheumatoid arthritis. Rheumatology (Oxford) 2021; 60:682-691.

Abstract
OBJECTIVE To determine the extent to which disease duration, alone or in combination with other baseline clinical and non-clinical factors, explains variations in outcome of tocilizumab initiated in biologic-naïve patients with established RA. METHODS In this pooled analysis of phase 3 and 4 clinical trials conducted by the sponsor, predictors of response, including demographics, disease characteristics at baseline (start of tocilizumab dosing) and study characteristics (e.g. patient inclusion criteria, tocilizumab dosing regimen) were evaluated. Response was measured as change from baseline to week 24 in Clinical Disease Activity Index (CDAI) and HAQ-Disability Index (HAQ-DI) scores and as the proportions of patients who experienced ≥50% improvement based on ACR criteria (ACR50) and CDAI remission (≤2.8) rates at week 24. RESULTS Improvements in all outcomes investigated were observed in patients receiving tocilizumab. Although disease duration was statistically significant in the models, it accounted for <2% of variation in CDAI and HAQ-DI score changes from baseline to week 24; baseline CDAI and HAQ-DI values accounted for 32% and 15% of variations, respectively. Doubling of disease duration reduced the odds of achieving an ACR50 response by only 9%, and each additional 5-year period of disease duration decreased the odds of achieving CDAI remission by only 15%. CONCLUSION RA duration, alone or in combination with other baseline characteristics, had a statistically significant but clinically small effect on the outcomes of tocilizumab initiated in biologic-naïve patients with established RA.

Superficial Ulcerating Rheumatoid Necrobiosis Associated with Methotrexate Use in a Patient with Rheumatoid Arthritis. EUROPEAN MEDICAL JOURNAL 2020.

Abstract
Methotrexate, a disease-modifying antirheumatic drug, is fundamental to limiting progression in several rheumatic diseases such as rheumatoid arthritis (RA). However, methotrexate is also associated with various significant adverse effects. Of note, there are several dermatologic manifestations attributed to methotrexate therapy. In particular, accelerated nodulosis and panniculitis are linked to methotrexate therapy in the current literature. The authors present the case of a 55-year-old Caucasian female with seropositive erosive RA who developed superficial ulcerating rheumatoid necrobiosis (SURN), secondary to methotrexate therapy. The patient’s treatment consisted of methotrexate discontinuation, topical clobetasol, and initiation of leflunomide as a replacement of methotrexate. Follow-up evaluation confirmed resolution of SURN over time and maintained low disease RA activity with leflunomide.Few cases describe SURN in the setting of RA and there are currently no cases published that suggest methotrexate’s possible role in SURN. Methotrexate-induced SURN is plausible in this case because of the correlation with therapy initiation and remission after therapy discontinuation. SURN has significant histological overlap with other methotrexate-induced dermatologic manifestations, allowing for a possible correlation. Most dermatological side effects of methotrexate are linked to a genetic predisposition of the HLA-DRB1 gene. Additionally, methotrexate’s mechanism of action for rheumatologic disease paradoxically stimulates adenosine-1 receptors and activates neutrophil chemotaxis and phagocytosis. Adenosine-1 receptor stimulation is hypothesised to be the source of rheumatoid-accelerated nodulosis and possibly SURN. Furthermore, the location of manifestation, genetic predisposition, and comorbid features in the patient all possibly have a role in this unique dermatological side effect.

Abstract
BACKGROUND Disparities in health care utilization and outcomes for racial and ethnic minorities with arthritis are well-established. However, there is a paucity of research on racial and ethnic differences in healthcare expenditures and if this relationship has changed over time. Our objectives were to: 1) examine trends in annual healthcare expenditures for adults with arthritis by race and ethnicity, and 2) determine if racial and ethnic differences in annual healthcare expenditures were independent of other factors such as healthcare access and functional disability. METHODS We used the Medical Expenditures Panel Survey (2008-2016) to examine trends in annual healthcare expenditures within and between racial and ethnic groups with arthritis (n = 227,663). A two-part model was used to estimate the marginal differences in expenditures by race and ethnicity after adjusting for relevant covariates, including the impact of healthcare access. RESULTS Between 2008 and 2016, there were no significant changes in unadjusted healthcare expenditures within any of the racial and ethnic groups, but the trend among non-Hispanic whites did differ significantly from Hispanics and Other. In fully adjusted analysis, mean annual expenditures for non-Hispanic whites was $946, $939, and $1178 more than non-Hispanic blacks, Hispanics, and Other, respectively (p < .001). Healthcare access also independently explained expenditure differences in this population with adults who delayed care spending significantly more ($2629) versus those who went without care spending significantly less (-$1591). CONCLUSIONS Race and ethnicity are independent drivers of healthcare expenditures among adults with arthritis independent of healthcare access and functional disability. This underscores the need for ongoing research on the factors that influence persistent racial and ethnic differences in this population.

Abstract
Background Black and Hispanic patients with osteoarthritis have more pain and worse function than Whites at the time of arthroplasty. Whether this is true for patients with rheumatoid arthritis (RA) is unknown. Methods This cross-sectional study used data on RA patients acquired between October 2013 and November 2018 prior to elective total knee (TKA) or hip arthroplasty (THA). Pain, function, and disease activity were assessed using the visual analogue scale (VAS), the Multidimensional Health Assessment Questionnaire (MDHAQ), and the Disease Activity Score (DAS28-ESR). We linked the cases to census tracts using geocoding to determine the community poverty level. Race, education, income, insurance and medications were collected via self-report. Using multivariable linear and logistic models we examined whether minority status predicted pain, function and RA disease activity at the time of arthroplasty. Results Thirty seven (23%) of the 164 patients were Black or Hispanic (minorities). The MDHAQ and DAS28-ESR were not significantly worse while VAS pain score was significantly worse in minority patients (p = 0.03). There was no significant difference in education between the groups. Insurance varied significantly; 29% of minority patients had Medicaid vs. 0% of Whites (p < 0.0001). In the multivariable analyses minority status was not significantly associated with DAS28-ESR [p = 0.66], MDHAQ [p = 0.26], or VAS pain [p = 0.18]. Conclusions For Black and/or Hispanic patients with RA undergoing THA or TKA at a high-volume specialty hospital, unlike Black or Hispanic patients with osteoarthritis (OA), there was no association with worse pain, function, or RA disease activity at the time of elective arthroplasty.

Abstract
Objective Early rheumatoid arthritis (RA) treatment requires timely recognition. This large, multicentre study compared patient-reported vs physician-reported onset of early RA. Methods Patients from the Canadian Early ArThritis CoHort with early/suspected RA (persistent synovitis <1 year) completed questionnaires asking about the date of symptom onset; and rheumatologists date of onset for persistent synovitis. Groups with similar reported timing (patient and physician) versus differing timing of 30 days or more were compared. Results In 2683 patients, the median patient symptom duration (IQR) was 178 days (163) and physician-reported duration was 166 (138). 1940 (72%) patients had similar patient-reported and physician-reported onset (<30 days), whereas 497 (18%) reported onset 30 or more days preceding physicians, and 246 (9%) 30 or more days after physicians. Patients reporting onset preceding physicians had lower baseline Disease Activity Score based on 28 joint count, swollen joint counts and erythrocyte sedimentation rate (p<0.05). Patients reporting onset after physicians were more likely to be rheumatoid factor positive (p<0.001) and had higher anticitrullinated protein antibody titres (p<0.009). Regression showed low income, smoking, fibromyalgia, osteoarthritis and baseline non-methotrexate non-biological disease-modifying antirheumatic drug use were predictors for longer patient-reported symptoms. At 12 months, patients reporting longer symptom duration than physicians had lower rates of Simplified Disease Activity Index remission and higher physician global assessments. Conclusion Over one-fourth of patients reported differences of >1 month in symptom onset from their rheumatologist. Patients with longer symptom durations had less improvement at 1 year, which may be reflective of comorbid musculoskeletal conditions.

Abstract
IMPORTANCE Prescribing the first biologic treatment for rheumatoid arthritis (RA) is an important decision for patients, their physicians, and payers, with considerable costs and clinical implications. Conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) have known effectiveness and safety profiles and are less expensive; therefore, determining the variables contributing to csDMARD treatment duration is an essential question for patients, physicians, and payers. OBJECTIVES To describe access to the first biologic DMARD prescription in a population of patients with RA and identical comprehensive health insurance coverage in Ontario, Canada, and to explore the associations of patient, prescriber, and geographic region with differences in time to first biologic prescription. DESIGN, SETTING, AND PARTICIPANTS This cohort study of incident patients with RA used administrative data with surveillance and patient-level data collected at yearly intervals. A total of 17 672 patients were included in the study; they were residents of Ontario, Canada, had an incident RA diagnosis at age 67 or older between 2002 and 2015, and received at least 1 csDMARD. Data were analyzed in November 2017. EXPOSURE Patient variables were age, sex, disease duration, socioeconomic status, distance to care, and supply of care in the patient's area of residence. Prescriber covariates were year of graduation, specialty of practice, and supply of rheumatologic care in the patient's geographic region. MAIN OUTCOMES AND MEASURES Time from first csDMARD prescription to receipt of first biologic medication. RESULTS Of 17 672 patients, 11 598 (65.6%) were women, and the mean (SD) age was 75.2 (5.8) years. Characteristics associated with longer time to receipt of a biologic prescription were older age (HR for every 5-year increase, 0.66; 95% CI, 0.62-0.71; P < .001), male sex (HR, 0.76; 95% CI, 0.66-0.89; P < .001), and distance to the nearest rheumatologist (HR per 10-km increase, 0.99; 95% CI, 0.98-0.99; P < .001). Prescribers were primarily rheumatologists (151 of 214 [70.6%]) and primary care physicians (26 of 214 [12.1%]). After adjusting for the number of patients eligible to receive biologic DMARDs, rheumatologists' preferences (ie, yearly prescription rates) for using biologic DMARDs increased over time, from 1.7% in 2001 to 4.9% in 2015. After adjusting for calendar year and patient-, prescriber-, and region-level characteristics, substantial variation between prescribers in rates of prescribing a first biologic DMARD were found (65% variance). CONCLUSIONS AND RELEVANCE This study found variation in time to receipt of first biologic DMARD after prescription of first csDMARD in a population with RA after adjustment for individual-level patient, prescriber, and geographic area covariates, despite identical universal health insurance coverage.

Effect of disease duration and prior disease-modifying antirheumatic drug use on treatment outcomes in patients with rheumatoid arthritis. Ann Rheum Dis 2019; 78:1609-1615. [PMID: 31434637 PMCID: PMC6900248 DOI: 10.1136/annrheumdis-2018-214918] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 07/01/2019] [Accepted: 07/25/2019] [Indexed: 01/29/2023]
Abstract
OBJECTIVES To determine if disease duration and number of prior disease-modifying antirheumatic drugs (DMARDs) affect response to therapy in patients with established rheumatoid arthritis (RA). METHODS Associations between disease duration or number of prior DMARDs and response to therapy were assessed using data from two randomised controlled trials in patients with established RA (mean duration, 11 years) receiving adalimumab+methotrexate. Response to therapy was assessed at week 24 using disease activity outcomes, including 28-joint Disease Activity Score based on C-reactive protein (DAS28(CRP)), Simplified Disease Activity Index (SDAI) and Health Assessment Questionnaire Disability Index (HAQ-DI), and proportions of patients with 20%/50%/70% improvement in American College of Rheumatology (ACR) responses. RESULTS In the larger study (N=207), a greater number of prior DMARDs (>2 vs 0-1) was associated with smaller improvements in DAS28(CRP) (-1.8 vs -2.2), SDAI (-22.1 vs -26.9) and HAQ-DI (-0.43 vs -0.64) from baseline to week 24. RA duration of >10 years versus <1 year was associated with higher HAQ-DI scores (1.1 vs 0.7) at week 24, but results on DAS28(CRP) and SDAI were mixed. A greater number of prior DMARDs and longer RA duration were associated with lower ACR response rates at week 24. Data from the second trial (N=67) generally confirmed these findings. CONCLUSIONS Number of prior DMARDs and disease duration affect responses to therapy in patients with established RA. Furthermore, number of prior DMARDs, regardless of disease duration, has a limiting effect on the potential response to adalimumab therapy.

Abstract
OBJECTIVE Most studies that have evaluated patient-reported outcomes, such as those utilizing the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Short Form 10a (PF10a) in rheumatoid arthritis (RA), have been performed in white and English-speaking populations. The aim of our study was to assess the measurement properties of the PF10a in a racially/ethnically diverse population with RA and to determine the effect of non-English language proficiency, insurance status, and race/ethnicity on the validity and responsiveness of the PF10a. METHODS Data were abstracted from electronic health records for all RA patients seen in a university-based rheumatology clinic between 2013 and 2017. We evaluated the use of the PF10a, floor and ceiling effects, and construct validity across categories of language preference, insurance, and race/ethnicity. We used standardized response means and linear mixed-effects models to evaluate the responsiveness of the PF10a to longitudinal changes in the Clinical Disease Activity Index (CDAI) across population subgroups. RESULTS We included 595 patients in a cross-sectional analysis of validity and 341 patients in longitudinal responsiveness analyses of the PF10a. The PF10a had acceptable floor and ceiling effects and was successfully implemented. We observed good construct validity and responsiveness to changes in CDAI among white subjects, English speakers, and privately insured patients. However, constructs evaluated by the PF10a were less correlated with clinical measures among Chinese speakers and Hispanic subjects, and less sensitive to clinical improvements among Medicaid patients and Spanish speakers. CONCLUSION While the PF10a has good measurement properties and is both practical and acceptable for implementation in routine clinical practice, we also found important differences across racial/ethnic groups and those with limited English proficiency that warrant further investigation.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic, debilitating disease associated with reduced quality of life and substantial costs. It is unclear which tests and assessment tools allow the best assessment of prognosis in people with early RA and whether or not variables predict the response of patients to different drug treatments. OBJECTIVE To systematically review evidence on the use of selected tests and assessment tools in patients with early RA (1) in the evaluation of a prognosis (review 1) and (2) as predictive markers of treatment response (review 2). DATA SOURCES Electronic databases (e.g. MEDLINE, EMBASE, The Cochrane Library, Web of Science Conference Proceedings; searched to September 2016), registers, key websites, hand-searching of reference lists of included studies and key systematic reviews and contact with experts. STUDY SELECTION Review 1 - primary studies on the development, external validation and impact of clinical prediction models for selected outcomes in adult early RA patients. Review 2 - primary studies on the interaction between selected baseline covariates and treatment (conventional and biological disease-modifying antirheumatic drugs) on salient outcomes in adult early RA patients. RESULTS Review 1 - 22 model development studies and one combined model development/external validation study reporting 39 clinical prediction models were included. Five external validation studies evaluating eight clinical prediction models for radiographic joint damage were also included. c-statistics from internal validation ranged from 0.63 to 0.87 for radiographic progression (different definitions, six studies) and 0.78 to 0.82 for the Health Assessment Questionnaire (HAQ). Predictive performance in external validations varied considerably. Three models [(1) Active controlled Study of Patients receiving Infliximab for the treatment of Rheumatoid arthritis of Early onset (ASPIRE) C-reactive protein (ASPIRE CRP), (2) ASPIRE erythrocyte sedimentation rate (ASPIRE ESR) and (3) Behandelings Strategie (BeSt)] were externally validated using the same outcome definition in more than one population. Results of the random-effects meta-analysis suggested substantial uncertainty in the expected predictive performance of models in a new sample of patients. Review 2 - 12 studies were identified. Covariates examined included anti-citrullinated protein/peptide anti-body (ACPA) status, smoking status, erosions, rheumatoid factor status, C-reactive protein level, erythrocyte sedimentation rate, swollen joint count (SJC), body mass index and vascularity of synovium on power Doppler ultrasound (PDUS). Outcomes examined included erosions/radiographic progression, disease activity, physical function and Disease Activity Score-28 remission. There was statistical evidence to suggest that ACPA status, SJC and PDUS status at baseline may be treatment effect modifiers, but not necessarily that they are prognostic of response for all treatments. Most of the results were subject to considerable uncertainty and were not statistically significant. LIMITATIONS The meta-analysis in review 1 was limited by the availability of only a small number of external validation studies. Studies rarely investigated the interaction between predictors and treatment. SUGGESTED RESEARCH PRIORITIES Collaborative research (including the use of individual participant data) is needed to further develop and externally validate the clinical prediction models. The clinical prediction models should be validated with respect to individual treatments. Future assessments of treatment by covariate interactions should follow good statistical practice. CONCLUSIONS Review 1 - uncertainty remains over the optimal prediction model(s) for use in clinical practice. Review 2 - in general, there was insufficient evidence that the effect of treatment depended on baseline characteristics. STUDY REGISTRATION This study is registered as PROSPERO CRD42016042402.

Abstract
BACKGROUND Rheumatoid arthritis (RA) has articular and non-articular manifestations. Early, intensive treatment has substantial benefit for both. This requires patients be identified as soon as symptoms develop. OBJECTIVES To determine whether selected signs and symptoms can be identified in the primary care records of patients prior to a formal diagnosis of RA being made and, if so, how early they can be identified. METHODS A case-control study was constructed within the UK Clinical Practice Research Datalink (CPRD). 3577 individuals with 'definite' RA, were matched to 14,287 individuals without inflammatory arthritis. An index date was established (i.e., date general practitioner (GP) first appeared to suspect RA). Rates of consultation and consultations for suspected early RA symptoms were compared in cases and controls in the two years prior to the index date using conditional logistic regression, adjusted for number of consultations. RESULTS The mean (standard deviation) age of participants was 58.8 (14.5) years and 66.8% were female. Rates of any consultation were significantly higher in RA cases than in controls for at least two years prior to the index date. Cases were more likely to have a pre-diagnosis coded consultation for joint, and particularly hand symptoms (aOR 11.44 (9.60, 13.63)), morning stiffness (8.10 (3.54, 18.5)), carpal tunnel syndrome (4.57 (3.54, 5.88)) and other non-articular features. CONCLUSIONS In patients who develop RA, GP consultation rates are higher for at least two years prior to the first recorded suspicion of RA. This study highlights symptoms that should raise a GP's index of suspicion for RA.

Abstract
The most severe effects of rheumatoid arthritis (RA) are loss of physical function and chronic pain, which may have a major impact on different areas of the person’s existence. The aim of this study was to get an insight into the quality of life (QOL) in subjects with RA in connection with pain perception and functional ability. The following instruments were used: the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), Short Form Health Survey (SF-36), Health Assessment Questionnaire Disability Index (HAQ-DI) and Visual Analog Scale for Pain (VAS Pain). The results indicated that there was no statistical difference in the QOL between subjects with RA and healthy population according to SF-36 Croatian norms. Also, the results showed that stronger pain experience was significantly associated with poorer social functioning assessment (SF36SF, Spearman’s rho=-0.463, p<0.05), poorer general health perception (SF36GH, Spearman’s rho=-0.432, p<0.05) and poorer physical functioning (WHOPH, Spearman’s rho=-0.688, p<0.01). Furthermore, the subjects evaluating their general functional state worse were found to have worse physical functioning (SF36PF, Spearman’s rho=-0.699 and WHOPH, Spearman’s rho=-0.769), poorer social functioning (SF36SF, Spearman’s rho=-0.580) and experienced greater pain intensity (SF36BP, Spearman’s rho=-0.652). Therefore, additional efforts should be invested to define a holistic and integrative model of treatment and rehabilitation of people with RA, focused on pain relief, improvement of functional ability, encouraging social interaction and supporting positive emotional responses.

Abstract
BACKGROUND Musculoskeletal (MSK) disorders are less likely to be reported as an underlying cause of death (UCD) and since cause of death studies are generally limited to the UCD, little is known about socioeconomic inequalities in MSK disorders as cause of death in the general population. Using multiple-cause-of-death data, we aimed to quantify and compare educational inequalities in musculoskeletal (MSK) disorders- with non-MSK disorders-related mortality. METHODS All residents aged 30-99 years in the Skåne region, Sweden, during 1998-2013 (n = 999,148) were followed until their 100th birthday, death, relocation outside Skåne, or end of 2014. We identified any mention of rheumatoid arthritis (RA) or other MSK disorders on death certificates using multiple-cause-of-death data. We retrieved and linked individual-level data from Statistics Sweden on highest level of education. We used Cox regression and additive hazards models with age as time-scale adjusted for sex, marital status, and country of birth to calculate slope and relative indices of inequality (SII/RII). RESULTS During a mean follow-up of 12.2 years, there were 1407 (0.8% of all deaths) and 3725 (2.1% of all deaths) death certificates with mention of RA and other MSK disorders, respectively, and 171,798 death certificates without any mention of a MSK disorder. Age-standardized RA mortality rate was 2.2 (95% confidence interval [CI]: 2.0-2.8) times greater in people with 0-9 years of education compared with those with > 12 years of education. Corresponding figure for other MSK disorders was 1.5 (95% CI: 1.4-1.6). Both RIIs and SIIs revealed statistically significant educational inequalities in RA/other MSK disorders mortality favouring high-educated people. The RIIs of MSK disorders-related deaths were generally greater than non-MSK disorders-related deaths. CONCLUSION We found substantial educational inequality in mortality from MSK disorders. Further research is needed to investigate underlying pathways driving these inequalities.

Abstract
OBJECTIVE To describe the character and composition of the 2015 US adult rheumatology workforce, evaluate workforce trends, and project supply and demand for clinical rheumatology care for 2015-2030. METHODS The 2015 Workforce Study of Rheumatology Specialists in the US used primary and secondary data sources to estimate the baseline adult rheumatology workforce and determine demographic and geographic factors relevant to workforce modeling. Supply and demand was projected through 2030, utilizing data-driven estimations regarding the proportion and clinical full-time equivalent (FTE) of academic versus nonacademic practitioners. RESULTS The 2015 adult workforce (physicians, nurse practitioners, and physician assistants) was estimated to be 6,013 providers (5,415 clinical FTE). At baseline, the estimated demand exceeded the supply of clinical FTE by 700 (12.9%). By 2030, the supply of rheumatology clinical providers is projected to fall to 4,882 providers, or 4,051 clinical FTE (a 25.2% decrease in supply from 2015 baseline levels). Demand in 2030 is projected to exceed supply by 4,133 clinical FTE (102%). CONCLUSION The adult rheumatology workforce projections reflect a major demographic and geographic shift that will significantly impact the supply of the future workforce by 2030. These shifts include baby-boomer retirements, a millennial predominance, and an increase of female and part-time providers, in parallel with an increased demand for adult rheumatology care due to the growing and aging US population. Regional and innovative strategies will be necessary to manage access to care and reduce barriers to care for rheumatology patients.

Abstract
OBJECTIVES We sought to characterize the correlation between diagnoses made during telerheumatology and face-to-face visits and to document patients' satisfaction with telerheumatology visits. METHODS This quality assurance study of the use of telerheumatology evaluated new patients referred to a Veterans Affairs rheumatology clinic. Patients were seen at a community clinic by a nurse practitioner with a rheumatologist participating in the encounter via telelink. All of the patients had a second face-to-face visit with the same rheumatologist. Diagnoses made during telerheumatology and face-to-face visits were compared. Patients' satisfaction with telerheumatology was ascertained. RESULTS Thirty-eight patients were included in the study. Initially, 23 were diagnosed as having an inflammatory or rheumatic condition; 15 were subsequently confirmed at the face-to-face visits. All of the patients with inflammatory, rheumatic conditions were identified at the telerheumatology visits. The overall correlation was 79% between the telerheumatology and face-to-face visits. Among patients with inflammatory, rheumatic conditions, 66% preferred a face-to-face visit compared with 41% among those without such conditions (not significant). Immediately after the telerheumatology visit, all of the patients gave a 10 out of 10 rating for satisfaction. During the subsequent telephone survey, 30 remained highly satisfied with the telemedicine encounter (10 out of 10 rating). CONCLUSIONS Telerheumatology at the Palo Alto Veterans Affairs was well received by patients; provided an accurate diagnosis of noninflammatory, nonrheumatic conditions; and may be appropriate for screening and prioritizing patients for in-person rheumatology clinics.

Abstract
BACKGROUND The influence of prior patterns of health care utilization on future health care utilization has had minimal investigation in populations with musculoskeletal disorders. OBJECTIVES The purpose of this study was to explore the relationship between presurgical health care utilization and postsurgical health care utilization in a population of patients undergoing hip surgery in the US Military Health System. METHODS In this observational cohort study, person-level data were collected for patients undergoing hip arthroscopy in the Military Health System from 2003 to 2015, capturing all encounters 12 months before and 24 months after surgery for every individual. Cluster analysis was used to categorize individuals with high and low health care utilization, based on preoperative health care visits. Unadjusted and adjusted Poisson and generalized linear models were generated. Health care utilization outcomes were targeted, including costs, visits, and medication use. RESULTS There were 1850 individuals in the final cohort (mean age, 32.18 years; 55.4% male). The high health care utilization group averaged 57.69 ± 25.87 visits, compared to 20.43 ± 8.36 visits in the low utilization group. There were significant differences between groups for total health care visits (58.17; 95% confidence interval [CI]: 57.39, 58.58), total health care costs ($11 539.71; 95% CI: $10 557.26, $12 595.04), hip-related visits (12.77; 95% CI: 12.59, 12.96), hip-related costs ($3325.07; 95% CI: $2886.43, $3804.51), days' supply of pain medications (752.67; 95% CI: 751.24, 754.11), opioid prescriptions (48.83; 95% CI: 48.47, 49.21), and cost of pain medications ($1074.80; 95% CI: $1011.91, $1137.68). CONCLUSION Presurgical patterns of health care utilization were associated with postsurgical patterns of health care utilization, indicating that those patients who used more care before surgery also used more care after surgery. Clinicians should consider prior patterns of health care utilization, including utilization unrelated to the index condition, when determining care plans and prognosis.

Disease-related outcomes influence prevalence of falls in people with rheumatoid arthritis. Ann Phys Rehabil Med 2018; 62:84-91. [PMID: 30278237 DOI: 10.1016/j.rehab.2018.09.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2018] [Revised: 09/03/2018] [Accepted: 09/07/2018] [Indexed: 10/28/2022]
Abstract
BACKGROUND Patients with rheumatoid arthritis (RA) are at increased risk of falls, with potential adverse outcomes. There is a considerable variation across studies regarding the prevalence of falls and its correlation with clinical data, disease-related outcomes and physical performance tests. OBJECTIVE The aim of this study was to evaluate the prevalence of falls and its association with clinical data, disease-related outcomes and physical performance tests. METHODS In this cross-sectional study, 113 RA patients were divided into 3 groups - "non-fallers", "sporadic fallers" and "recurrent fallers" - and compared in terms of clinical data, Clinical Disease Activity Index (CDAI), lower-limb tender and swollen joint count, disability (Health Assessment Questionnaire-Disability Index [HAQ-DI]), Foot Function Index (FFI), Berg Balance Scale (BBS), Timed-up-and-go Test (TUG) and 5-Time Sit Down-To-Stand Up Test (SST5). Logistic regression analysis was performed to analyze the associations between the studied variables and the occurrence of falls, estimating odds ratios (ORs). We also analyzed the correlation between disease outcome measures (HAQ-DI and CDAI) and physical tests (BBS, TUG, SST5). RESULTS Falls and fear of falling were reported by 59 (52.21%) and 71 (64.5%) patients, respectively. Significant associations were found between "recurrent fallers" and vertigo (OR=3.42; P=0.03), fear of falling (OR=3.44; P=0.01), low income (OR=2.02; P=0.04), CDAI (OR=1.08; P<0.01), HAQ-DI (OR=3.66; P<0.01), Lower-limb HAQ (OR=3.48; P<0.01), FFI-pain (OR=1.24; P=0.03), FFI-total (OR=1.23; P=0.04), lower-limb tender joint count (OR=1.22; P<0.01), BBS score (OR=1.14; P<0.01), TUG score (OR=1.13; P=0.03) and SST5 score (OR=1.06; P=0.02). On multivariate analysis, CDAI was the only significant predictor of recurrent falls (OR=1.08; P<0.01). Physical performance test scores (BBS, TUG, SST5) were correlated with the CDAI and HAQ-DI. CONCLUSION The prevalence of falls in RA is high, most influenced by disease-related outcomes and linked to worse performance on physical tests (BBS, TUG and SST5).

Abstract
BACKGROUND The wrist is often severely affected in rheumatoid arthritis (RA) patients; however, little is known about the potential risk factors of the reduced wrist range of motion. In this study, we explored a broad range of possible risk factors of wrist range of motion in RA patients. We also determined whether measurements of wrist range of motion reflect Sharp score for the wrists. METHODS Active wrist volar flexion, dorsal flexion, radial deviation and ulnar deviation were assessed using a goniometer. RA patients underwent standardized laboratory and radiographic examinations and completed several questionnaires. A linear regression model was used to study association between the wrist range of motion and independent variables. In addition, Spearman and Pearson correlation analysis were used to compare influence factors and outcome measurements between the measurements of wrist range of motion and Sharp score for the wrists. RESULTS In this study, lower socioeconomic status, longer disease duration, severe pain, higher disease activity and drug treatments were associated with reduced wrist range of motion in RA patients (n = 102, 86.3% female, mean ± SD age, 55.0 ± 11.7 years, and mean ± SD disease duration, 8.4 ± 8.7 years). Furthermore, wrist range of motion was highly correlated with Sharp score for the wrists (P < 0.05). CONCLUSIONS Socioeconomic status and disease-specific factors were significantly associated with wrist range of motion in RA patients. The results indicated that rheumatologists and nurses should note the measurements of wrist range of motion in RA patients, especially those with a low socioeconomic status, a long disease duration, severe pain, and high disease activity to develop strategies to improve their quality of life.

Abstract
BACKGROUND Early treatment ensures optimal outcomes in rheumatoid arthritis (RA) yet there are limited data in Australia quantifying treatment delays in clinical practice. AIMS To quantify treatment delays in new RA patients and to explore factors influencing delay and resultant patient outcomes. METHODS Data were obtained for 88 patients presenting with a new diagnosis of RA to an early arthritis clinic (EAC) in Australia between 2008 and 2015. Date and details of symptom onset, initial general practitioner (GP) presentation, GP referral and review at EAC were collected. Patient demographics and clinical features were analysed for outcomes and features predictive of delay. RESULTS Median overall delay from symptom onset to rheumatology review was 26.4 weeks. Patient delay (8.7 weeks) was the longest delay and predicted overall delay. Delays in GP referral and time to EAC review were 4 and 8.4 weeks respectively. Increased overall delay was predicted by lower fatigue and disease activity scores (DAS28) and increased tender joint counts (TJC). Patient delay was increased by socioeconomic disadvantage. Increased GP delay was associated with lower DAS28 and higher TJC and ESR. Patients seen within 16 weeks had greater improvement in DAS28 and probability of remission at 6 months. CONCLUSIONS In this Australian EAC setting, patient delay was the greatest contributor to RA treatment delay. Delays in treatment were associated with lower disease severity and socioeconomic disadvantage. Remission was more likely after prompt initiation of treatment.

Abstract
We assessed potential predictors of sustained remission for 2 years according to the Disease Activity Score in 28 joints (DAS28)-CRP in patients with rheumatoid arthritis (RA). We obtained data for 290 RA outpatients, from July 2009 to September 2012. Sociodemographic data and answers to questionnaires were collected in face-to-face interviews. Remission was defined according to DAS28-CRP. Sustained remission was defined as meeting criteria for remission in the annual assessment for two consecutive years. Predictive factors of sustained remission according to DAS28-CRP were assessed by univariate and multivariate analyses. Of the 290 RA patients, the baseline remission level, according to DAS28-CRP, was 54.5%. During 2 years of follow-up, the sustained remission rate was 24.5%. RA patients who achieved sustained remission, according to DAS28-CRP, were younger, and had a shorter duration of symptoms, longer period of education, higher monthly income, lower Health Assessment Questionnaire (HAQ) score, lower physician global assessment, lower patient global assessment, lower patient pain assessment, and higher EQ-5D at baseline. Multivariate analyses showed that the baseline HAQ score was independently associated with sustained remission for 2 years according to DAS28-CRP (OR 0.298, 95% CI 0.115-0.770; p = 0.012). A lower HAQ score at baseline was an independent predictor of sustained remission at 2 years, according to DAS28-CRP. Thus, HAQ scores could be useful when stratifying patients according to risk for flare-ups in the clinic.

Predictors of patient decision to discontinue anti-rheumatic medication in patients with rheumatoid arthritis: results from the Ontario best practices research initiative. Clin Rheumatol 2017; 36:2421-2430. [PMID: 28879413 DOI: 10.1007/s10067-017-3805-4] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2017] [Revised: 08/16/2017] [Accepted: 08/25/2017] [Indexed: 01/28/2023]
Abstract
Despite the availability of treatment guidelines and effective treatments, real-world effectiveness remains suboptimal partly due to poor patient medication adherence. We evaluated a comprehensive set of sociodemographic, health insurance, and disease-related factors for association with patient decision to discontinue anti-rheumatic medications (ARMs) in a large observational RA cohort in Ontario, Canada. Patients from the Ontario Best Practices Research Initiative registry were included. The following predictors of ARM discontinuation were evaluated with cox-regression: patient age, gender, education, income, smoking, health insurance type/coverage, RA duration, erosion presence, RF positivity, DAS28-ESR, physician global, HAQ-DI, comorbidity number, ARM types, and physician characteristics (gender, academic position, urban vs. rural, distance from patient's residence). Patients (1762) were included with a mean (SD) age of 57.4 years (13.0). Approximately 80% were female, 29% had early (≤ 1 year) RA, and 70% were RF-positive. Mean (SD) baseline DAS28-ESR and HAQ-DI were 4.5 (1.5) and 1.2 (0.76), respectively. In multivariate analysis, married status (HR [95%CI] 0.73 [0.56-0.96]), RF positivity (0.73 [0.56-0.96]), and higher comorbidity number (0.92 [0.85-0.99]) were significant predictors of ARMs continuation while higher physician global (1.10 [1.04-1.15]), NSAID use (1.75 [1.29-2.38]), and number of ARMs (1.23 [1.07-1.40]) were associated with ARMs discontinuation. In a subset analysis assessing conventional or biologic DMARD discontinuation, higher HAQ-DI and biologic use over time were associated with lower hazard for discontinuation. Several sociodemographic, disease, and treatment parameters were identified as independent predictors of patient discontinuation of ARMs. These results should be considered when developing patient adherence support programs and in the choice of treatment regimens.

Abstract
BACKGROUND Even after achieving tremendous advances in diagnosis and treatment of rheumatoid arthritis (RA), many of the patients undergo delays in diagnosis and initiation of treatment, which leads to worsening of the condition and poor prognosis. OBJECTIVE The objective of this study was to perform a literature review to quantify the lag times in diagnosis and treatment of RA and study the reported factors associated with it. METHODS The authors searched literature published until September 2016 in electronic full-text and abstract databases and hand-searched the suitable articles. RESULTS The weighted average of median lag time from symptom onset to therapy was 11.79 months (12 studies, 5,512 patients, range 3.6-24.0 months). Lag1 was 3.14 months (onset of symptoms to first physician consultant; 12 studies, 6,055 patients, range 0-5.7 months); lag2 was 2.13 months (physician visit to RA specialist referral; 13 studies, 34,767 patients, range 0.5-6.6 months); lag3 was 2.91 months (consultation with rheumatologist to diagnosis; 3 studies, 563 patients, range 0-5 months), lag4 was 2.14 months (diagnosis to initiation of disease-modifying antirheumatic drug therapy; 5 studies, 30,685 patients, range 0-2.2 months). Numerous patient-and physician-related factors like gender, ethnicity, primary care physician knowledge of the condition, availability of diagnostics, and so on were responsible for the delays. CONCLUSION This review estimated the delay times and identified the main factors for delay in RA patients in diagnosis and initiation of treatment. A most plausible solution to this is coordinated effort by the rheumatology and primary care physicians.

Abstract
Background There have been no previous report of hand joint destruction prevalence in Chinese rheumatoid arthritis (RA) patients. Therefore, the aim of this study was to investigate the prevalence and potential factors of hand joint destruction among RA patients from Nantong China. In addition, we wanted to examine the differences between functional capacity, psychological status, and quality of life in patients with hand joint destruction compared to those without hand joint destruction. Methods A cross-sectional study was conducted from the Affiliated Hospital of Nantong University between July 2015 and June 2016. RA patients completed questionnaires for demographic or clinical variables, the 10-cm Visual Analog Scale for pain, the 28-joint Disease Activity Score-erythrocyte sedimentation rate for disease activity, the Health Assessment Questionnaire-disability index for physical function, the Hospital Anxiety and Depression Scale for anxiety and depression, and the Short Form 36 health survey for quality of life. Laboratory examinations were taken to obtain some biochemical indicators (e.g., rheumatoid factor, anti-cyclic citrullinated peptide antibody). X-ray assessment of hand was performed and hand joint destruction was defined as Sharp score > 0. Independent sample t-test, Mann–Whitney U-test, Chi-square test, and multivariate analysis using backward stepwise logistic regression model were used to analyze these data. Results One hundred and sixty-one RA patients were included in this study. Radiographic findings revealed that almost 47.2% (n = 76) of patients had hand joint destruction. Multivariate analysis found that education ≤ 9 years (p = 0.041), anti-cyclic citrullinated peptide antibody positive (p = 0.021), high disease activity (p = 0.020), and long disease duration (p < 0.001) were important potential risk factors of hand joint destruction. Participants with hand joint destruction tended to have lower physical function and quality of life, and more severe depressive symptoms compared to individuals without hand joint destruction. Conclusions 47.2% of people with RA from Nantong China experienced hand joint destruction. Education, anti-cyclic citrullinated peptide antibody, disease activity, and disease duration had great impacts on hand joint destruction. The results suggested that rheumatologists should pay attention to RA patients’ hand joint destruction, especially those with low education levels, anti-cyclic citrullinated peptide antibody positive, high disease activity, and long disease duration by patient education or other ways to improve patients’ prognosis.

METHODS Persons with rheumatoid arthritis (RA) diagnosis (International Classification of Diseases, 10th ed. codes M05/M06) on health insurance claims data in at least 2 quarters of 2013 were randomly selected. They were mailed questionnaires covering RA diagnosis, household income, functional capacity [Hannover functional status questionnaire (FFbH), 0-100], RA Impact of Disease questionnaire (RAID; 0-10), self-reported swollen joint count (SJC; 0-48), tender joint count (TJC; 0-50), and effect of RA on work productivity (change of work, fewer working hours, sick leave, application for disability pension, and others). Weighted multivariable linear regression models were used to assess the association between income and disease outcomes. RESULTS A total of 1492 persons of working age who confirmed RA diagnosis were available for analysis. The mean age was 55 years, 82% were women, and 74% were under rheumatologic care. A total of 27%, 52%, and 21% had a low (< €1500), medium (€1500-3200), and high monthly income (> €3200), respectively. Respondents with low income had the worst mean FFbH, RAID, SJC, and TJC values. This was confirmed in the regression model: mean FFbH low versus high income -8.65 (95% CI -9.72 to -7.58), RAID 0.73 (0.59-0.86), and SJC 3.47 (2.86-4.08). Sick leave (8.7%/3.5%/1.8%) and disability pension (18.1%/9.6%/6.9%) were more frequent in patients with low versus medium versus high income (p < 0.05). CONCLUSION The association of low income with a higher disease burden, more functional disability, and higher rates of work loss emphasizes the need to focus on these outcomes when choosing treatment strategies for patients in the lower income groups.

Abstract
Autoimmune diseases (ADs) represent a heterogeneous group of disorders that affect specific target organs or multiple organ systems. These conditions share common immunopathogenic mechanisms (i.e., the autoimmune tautology), which explain the clinical similarities they have among them as well as their familial clustering (i.e., coaggregation). As part of the autoimmune tautology, the influence of environmental exposure on the risk of developing ADs is paramount (i.e., the autoimmune ecology). In fact, environment, more than genetics, shapes immune system. Autoimmune ecology is akin to exposome, that is all the exposures - internal and external - across the lifespan, interacting with hereditary factors (both genetics and epigenetics) to favor or protect against autoimmunity and its outcomes. Herein, we provide an overview of the autoimmune ecology, focusing on the immune response to environmental agents in general, and microbiota, cigarette smoking, alcohol and coffee consumption, socioeconomic status (SES), gender and sex hormones, vitamin D, organic solvents, and vaccines in particular. Inclusion of the autoimmune ecology in disease etiology and health will improve the way personalized medicine is currently conceived and applied.
