Interpersonal violence and painful bladder symptoms in community-dwelling midlife to older women.

BACKGROUND: Women are more likely to present with genitourinary complaints immediately after exposure to interpersonal violence, but little is known about the long-term effects of violence on women's urologic health, including their susceptibility to bladder pain and infections. OBJECTIVE: To determine whether lifetime interpersonal violence exposure and current posttraumatic stress disorder (PTSD) symptoms are associated with the prevalence or severity of painful bladder symptoms and a greater lifetime history of antibiotic-treated urinary tract infections in community-dwelling midlife and older women. STUDY DESIGN: We examined the cross-sectional data from a multiethnic cohort of community-dwelling women aged 40 to 80 years enrolled in a northern California integrated healthcare system. Women completed structured self-report questionnaires about their past exposure to physical and verbal/emotional intimate partner violence and sexual assault. The symptoms of PTSD were assessed using the PTSD checklist for the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Civilian version. Additional structured self-report measures assessed the current bladder pain, other lower urinary tract symptoms, and the history of antibiotic-treated urinary tract infections. Multivariable logistic regression models examined self-reported interpersonal violence exposure history and current PTSD symptoms in relation to current bladder pain and antibiotic-treated urinary tract infection history. RESULTS: Among 1974 women (39% non-Latina White, 21% Black, 20% Latina, and 19% Asian), 22% reported lifetime interpersonal violence exposure, 22% reported bladder pain, and 60% reported a history of ever having an antibiotic-treated urinary tract infection. Lifetime experiences of sexual assault (odds ratio, 1.39; [95% confidence interval, 1.02-1.88]) and current PTSD symptoms (odds ratio, 1.96; [95% confidence interval, 1.45-2.65]) were associated with current bladder pain. A lifetime experience of physical intimate partner violence was associated with having a urinary tract infection at any time in life previously (odds ratio, 1.38; [95% confidence interval, 1.00-1.86]), as was emotional intimate partner violence (odds ratio, 1.88; [95% confidence interval, 1.43-2.48]), sexual assault (odds ratio, 1.44; [95% confidence interval, 1.09-1.91]), and current PTSD symptoms (odds ratio, 1.54; [95% confidence interval, 1.16-2.03]). CONCLUSION: In this ethnically diverse, community-based cohort, lifetime interpersonal violence exposures and current PTSD symptoms were independently associated with current bladder pain and the lifetime history of antibiotic-treated urinary tract infections in midlife to older women. The findings suggest that interpersonal violence and PTSD symptoms may be underrecognized markers of risk for urologic pain and infections in women, highlighting a need for trauma-informed care of these issues.

Nurse Practitioners and Physician Assistants: An Underestimated Workforce for Older Adults with Cancer.

OBJECTIVES: To describe the composition of the US provider workforce for adults with cancer older than 65 years and to determine whether there were differences in patients who received care from different providers (eg, nurse practitioners [NPs], physician assistants [PAs], and specialty physicians). DESIGN: Observational, cross-sectional study. SETTING: Adults within the 2013 Surveillance, Epidemiology, and End Results cancer registries linked to the Medicare claims database. PARTICIPANTS: Medicare beneficiaries who received ambulatory care for any solid or hematologic malignancies. MEASUREMENTS: International Classification of Diseases, Ninth Revision (ICD-9), diagnosis codes were used to identify Medicare patient claims for malignancies in older adults. Providers for those ambulatory claims were identified using taxonomy codes associated with their National Provider Identifier number. RESULTS: A total of 2.5 million malignancy claims were identified for 201, 237 patients, with 15, 227 providers linked to claims. NPs comprised the largest group (31.5%; n = 4,806), followed by hematology/oncology physicians (27.7%; n = 4,222), PAs (24.7%; n = 3767), medical oncologists (10.9%; n = 661), gynecological oncologists (2.6%; n = 403), and hematologists (2.4%; n = 368). Rural cancer patients were more likely to receive care from NPs (odds ratio [OR] = 1.84; 95% confidence interval [CI] = 1.65-2.05) or PAs (OR = 1.57; 95% CI = 1.40-1.77) than from physicians. Patients in the South were more likely to receive care from NPs (OR = 1.36; 95% CI = 1.24-1.49). CONCLUSIONS: A large proportion of older adults with cancer receive care from NPs and PAs, particularly those who reside in rural settings and in the southern United States. Workforce strategies need to integrate these provider groups to effectively respond to the rising need for cancer care within the older adult population.

Using health-system-wide data to understand hepatitis B virus prophylaxis and reactivation outcomes in patients receiving rituximab.

Hepatitis B virus (HBV) reactivation in the setting of rituximab use is a potentially fatal but preventable safety event. The rate of HBV screening and proportion of patients at risk who receive antiviral prophylaxis in patients initiating rituximab is unknown.We analyzed electronic health record (EHR) data from 2 health systems, a university center and a safety net health system, including diagnosis grouper codes, problem lists, medications, laboratory results, procedures codes, clinical encounter notes, and scanned documents. We identified all patients who received rituximab between 6/1/2012 and 1/1/2016. We calculated the proportion of rituximab users with inadequate screening for HBV according to the Centers for Disease Control guidelines for detecting latent HBV infection before their first rituximab infusion during the study period. We also assessed the proportion of patients with positive hepatitis B screening tests who were prescribed antiviral prophylaxis. Finally, we characterized safety failures and adverse events.We included 926 patients from the university and 132 patients from the safety net health system. Sixty-one percent of patients from the university had adequate screening for HBV compared with 90% from the safety net. Among patients at risk for reactivation based on results of HBV testing, 66% and 92% received antiviral prophylaxis at the university and safety net, respectively.We found wide variations in hepatitis B screening practices among patients receiving rituximab, resulting in unnecessary risks to patients. Interventions should be developed to improve patient safety procedures in this high-risk patient population.

Variations in Radiographic Procedure Use for Medicare Patients With Rheumatoid Arthritis.

OBJECTIVE: In 2013, the American College of Rheumatology published its Choosing Wisely list, which identified 2 radiographic procedures (peripheral joint magnetic resonance imaging [MRI] and dual x-ray absorptiometry [DXA] scans) that were at risk for overuse. METHODS: We performed a retrospective cross-sectional cohort study to measure the use of peripheral joint MRI, peripheral joint radiographs, and DXA scans in a national cohort of Medicare patients with rheumatoid arthritis (RA) during 2008-2009, before the start of the Choosing Wisely campaign. Diagnoses were identified via International Classification of Diseases, Ninth Revision, codes; utilization was calculated using Current Procedural Terminology codes. Utilization was analyzed at the individual level and at the regional level (by hospital referral region [HRR]). RESULTS: There were 8,051 patients with RA who were included: 81% were women, and the mean age was 76 years. Over a 2-year period, the mean number of peripheral joint MRIs per beneficiary was 0.3 (median 0 [range 0-50]), peripheral joint radiographs per beneficiary was 2.6 (median 1 [range 0-33]), and DXA scans per beneficiary was 0.7 (median 0 [range 0-11]). Only 6.8% of patients received >1 peripheral joint MRI, and 6% of HRRs had a mean number of peripheral joint MRIs >1. CONCLUSION: There is variation in the use of peripheral joint MRI, peripheral joint radiographs, and DXA scans among Medicare patients with RA, although only a small number of HRRs have consistently high utilization. Although we cannot judge the appropriateness of each procedure, variation in use across regions signals the need for investigations to examine potential overutilization.

A new era of quality measurement in rheumatology: electronic clinical quality measures and national registries.

PURPOSE OF REVIEW: This article reviews the evolution of quality measurement in rheumatology, highlighting new health-information technology infrastructure and standards that are enabling unprecedented innovation in this field. RECENT FINDINGS: Spurred by landmark legislation that ties physician payment to value, the widespread use of electronic health records, and standards such as the Quality Data Model, quality measurement in rheumatology is rapidly evolving. Rather than relying on retrospective assessments of care gathered through administrative claims or manual chart abstraction, new electronic clinical quality measures (eCQMs) allow automated data capture from electronic health records. At the same time, qualified clinical data registries, like the American College of Rheumatology's Rheumatology Informatics System for Effectiveness registry, are enabling large-scale implementation of eCQMs across national electronic health record networks with real-time performance feedback to clinicians. Although successful examples of eCQM development and implementation in rheumatology and other fields exist, there also remain challenges, such as lack of health system data interoperability and problems with measure accuracy. SUMMARY: Quality measurement and improvement is increasingly an essential component of rheumatology practice. Advances in health information technology are likely to continue to make implementation of eCQMs easier and measurement more clinically meaningful and accurate in coming years.

Folic Acid Supplementation Is Suboptimal in a National Cohort of Older Veterans Receiving Low Dose Oral Methotrexate.

OBJECTIVES: Co-prescription of folic acid in patients receiving low dose oral methotrexate is recommended because it reduces adverse events and prolongs the use of methotrexate (MTX). However, little is known about how often new users of methotrexate are co-prescribed folic acid, and what factors are associated with its use. We aimed to determine the prevalence, predictors of, and persistence of folic acid use in a population-based cohort of MTX users with rheumatic diseases. METHODS: Using a national, administrative database of patients seen through the Veterans Health Administration (VHA) that included pharmacy and laboratory data, we performed an observational cohort study of veterans over 65 years old who were new users of MTX. We used log-binomial regression to identify independent predictors of folic acid use and Kaplan Meyer survival analysis to examine persistence of folic acid over time. RESULTS: We studied 2467 incident users of MTX. 27% of patients were not prescribed folic acid through the VHA pharmacy within 30 days of MTX initiation. Patients who did not see a rheumatologist were 23% less likely to receive folic acid compared to patients who did have a rheumatologist visit during the baseline period (RR (95% CI) 0.77 (0.72, 0.82). These results remained unchanged even after adjusting for demographic, clinical, and other factors (adjusted RR (95% CI) 0.78 (0.74, 0.85)). After 20 months, only 50% of patients continued to receive folic acid. CONCLUSIONS: In a nationwide VHA cohort of new users of oral MTX, many patients did not receive folic acid or discontinued it over time. Rheumatologists were more likely to prescribe folic acid than other providers. These data highlight the need to improve patient safety for users of methotrexate by standardizing workflows for folic acid supplementation.

Factors associated with access to rheumatologists for Medicare patients.

OBJECTIVE: Despite looming rheumatologist shortages and a growing number of patients with arthritis and other rheumatic conditions, nationwide estimates of access to rheumatology care have never been reported. We aimed to measure travel times as a proxy to access to care and to determine the individual and area-level factors associated with long travel times to rheumatologists in the U.S. METHODS: We used Medicare Part B claims for the 2009 Medicare Chronic Condition Warehouse 5% rheumatoid arthritis/osteoarthritis cohort. Using Google Maps we estimated driving time from the center of a beneficiary's home ZIP code to the center of their rheumatologist's office ZIP code. We examined predictors of travel time ≥90 min in a series of generalized linear mixed models adjusting for rheumatologist supply, rurality, and individual patient characteristics including age, race, gender, and income. RESULTS: We included 41,693 Medicare beneficiaries with 1 or more visits to a rheumatologist in 2009. The median estimated beneficiary travel time to a rheumatologist was 22 min [interquartile range (IQR): 12-40 min]. Overall, 7% of beneficiaries traveled 90 min or longer to visit a rheumatologist. Even after adjusting for covariates, independent predictors of long travel times included living in areas with no or low supply of rheumatologists and living in the Mountain region of the U.S. CONCLUSIONS: A small but significant proportion of patients in the U.S. traveled very long distances to visit a rheumatologist, and most of these individuals resided in areas with no or low supplies of rheumatologists. These data suggest that addressing shortages in rheumatology care for patients in low-supply areas is a key target for improving access to rheumatologists.

Use and Spending for Biologic Disease-Modifying Antirheumatic Drugs for Rheumatoid Arthritis Among US Medicare Beneficiaries.

OBJECTIVE: Biologic therapies have assumed an important role in treating rheumatoid arthritis (RA). We sought to investigate use, spending, and patient cost-sharing for Medicare beneficiaries using biologic drugs for RA, comparing patients exposed to minimal cost-sharing because of a Part D low-income subsidy (LIS) to those facing substantial out-of-pocket costs (OOP). METHODS: We performed a retrospective, nationwide study using 2009 Medicare claims for a 5% random sample of beneficiaries with RA who had at least 1 RA drug dispensed. We analyzed biologic drug utilization and costs across the Part B (medical benefit) and Part D (pharmacy benefit) programs by LIS status using multinomial regression. We also projected OOP costs as the Affordable Care Act (ACA) mandates closure of the Part D coverage gap by 2020. RESULTS: Among 6,932 beneficiaries, 1,812 (26.1%) received a biologic drug. LIS beneficiaries were significantly more likely to obtain Part D home-administered biologics (relative risk ratio [RRR] 2.98, 95% confidence interval [95% CI] 2.50-3.56), while non-LIS beneficiaries were less likely to receive Part D biologic agents (RRR 0.58, 95% CI 0.48-0.69). OOP costs in Part D were lower, as expected, for LIS beneficiaries ($72 versus $3,751 per year for non-LIS). Non-LIS beneficiaries had lower costs for Part B facility-administered biologic agents (range $0-$2,584) than for Part D home-administered biologic agents. ACA reforms will narrow OOP differences between Part D and B for non-LIS beneficiaries. CONCLUSION: In contrast to LIS beneficiaries who receive mostly Part D home-administered biologic DMARDs, nonsubsidized beneficiaries have significant cost-based incentives to obtain facility-administered biologic DMARDs through Part B. The ACA will result in only slightly lower costs for Part D biologic drugs for these beneficiaries.

Interactions between patients, providers, and health systems and technical quality of care.

OBJECTIVE: Prior studies have established disparities by race/ethnicity and socioeconomic status (SES) in the kind, quantity, and technical quality of systemic lupus erythematosus (SLE) care and outcomes. In this study we evaluate whether disparities exist in assessments of interactions with health care providers and health plans and whether such interactions affect the technical quality of SLE care. METHODS: Data derive from the Lupus Outcomes Study (LOS). Principal data collection is an annual structured phone interview including items from the Consumer Assessment of Health Plans and Interpersonal Processes of Care Scale measuring dimensions of health care interactions. We use general estimating equations to assess whether disparities exist by race/ethnicity and SES in being in the lowest quartile of ratings of such interactions and whether ratings in the lowest quartile of interactions are associated with technical quality of care after adjustment for sociodemographic and disease characteristics. RESULTS: In the 2012 LOS interview, there were 793 respondents, of whom 640 had ≥1 visit to their principal SLE provider. Nonwhite race/ethnicity and education were not associated with low ratings on any dimension of provider or system interaction; poverty was associated only with low ratings of health plan interactions. After adjustment for demographics, SLE status, and health care variables, ratings in the lowest quartile on all dimensions were associated with significantly lower technical quality of care. CONCLUSION: Ratings in the lowest quartile on all dimensions of interactions with providers and the health care system were associated with lower technical quality of care, potentially resulting in poorer SLE outcomes.

Receipt of glucocorticoid monotherapy among Medicare beneficiaries with rheumatoid arthritis.

OBJECTIVE: Using disease-modifying antirheumatic drugs (DMARDs) improves outcomes in rheumatoid arthritis (RA) and is a nationally endorsed quality measure. We investigated the prevalence and predictors of receiving glucocorticoids alone for the treatment of RA in a nationwide sample of Medicare beneficiaries. METHODS: Among individuals ages ≥65 years with RA enrolled in the Part D prescription drug benefit in 2009, we compared those with ≥1 DMARD claim to those receiving glucocorticoid monotherapy, defined as no DMARD claim and an annual glucocorticoid supply of ≥180 days or an annual dose of ≥900 mg of prednisone or equivalent. We fit multivariable models to determine the sociodemographic and clinical factors associated with glucocorticoid monotherapy. RESULTS: Of 8,125 beneficiaries treated for RA, 10.2% (n = 825) received glucocorticoids alone. Beneficiaries with low incomes were more likely to receive glucocorticoids alone (12.3%; 95% confidence interval [95% CI] 10.9-13.8% versus 9.4%; 95% CI 8.6-10.1%), as were those living in certain US regions. More physician office visits and hospitalizations were associated with glucocorticoid monotherapy. Individuals who had no contact with a rheumatologist were significantly more likely to receive glucocorticoids alone (17.5%; 95% CI 16.0-19.0% versus 8.5%; 95% CI 7.4-9.5% for those with no rheumatology visits versus 1-4 visits). CONCLUSION: Approximately 1 in 10 Medicare beneficiaries treated for RA received glucocorticoids without DMARDs in 2009. Compared to DMARD users, glucocorticoid users were older, had lower incomes, were more likely to live in certain US regions, and were less likely to have seen a rheumatologist, suggesting persistent gaps in quality of care despite expanded drug coverage under Part D.

English language proficiency, health literacy, and trust in physician are associated with shared decision making in rheumatoid arthritis.

OBJECTIVE: Treat-to-target guidelines promote shared decision making (SDM) in rheumatoid arthritis (RA). Also, because of high cost and potential toxicity of therapies, SDM is central to patient safety. Our objective was to examine patterns of perceived communication around decision making in 2 cohorts of adults with RA. METHODS: Data were derived from patients enrolled in 1 of 2 longitudinal, observational cohorts [University of California, San Francisco (UCSF) RA Cohort and RA Panel Cohort]. Subjects completed a telephone interview in their preferred language that included a measure of patient-provider communication, including items about decision making. Measures of trust in physician, education, and language proficiency were also asked. Logistic regression was performed to identify correlates of suboptimal SDM communication. Analyses were performed on each sample separately. RESULTS: Of 509 patients across 2 cohorts, 30% and 32% reported suboptimal SDM communication. Low trust in physician was independently associated with suboptimal SDM communication in both cohorts. Older age and limited English proficiency were independently associated with suboptimal SDM in the UCSF RA Cohort, as was limited health literacy in the RA Panel Cohort. CONCLUSION: This study of over 500 adults with RA from 2 demographically distinct cohorts found that nearly one-third of subjects report suboptimal SDM communication with their clinicians, regardless of cohort. Lower trust in physician was independently associated with suboptimal SDM communication in both cohorts, as was limited English language proficiency and older age in the UCSF RA Cohort and limited health literacy in the RA Panel Cohort. These findings underscore the need to examine the influence of SDM on health outcomes in RA.

Relationships between driving distance, rheumatoid arthritis diagnosis, and disease-modifying antirheumatic drug receipt.

OBJECTIVE: Disease-modifying antirheumatic drugs (DMARDs) are recommended for all patients with rheumatoid arthritis (RA). Some estimate that approximately one-half of patients with RA do not receive DMARDs. We hypothesized that patients with RA living farther from rheumatologists would be less likely to receive RA diagnoses and to receive DMARDs. METHODS: US-based Medicare patients ages >65 years were study eligible. We calculated driving distance from patients' homes to the nearest rheumatologist. Using multivariable logistic regression, we assessed relationships between driving distance and RA diagnosis and between driving distance and DMARD receipt. In one set of analyses, distance was divided into quartiles: 0-2, 2.1-5, 5.1-15.9, and ≥16 miles. In a second set of analyses, we used predefined categories: 0-15, 15.1-30, 30.1-60, and >60 miles. RESULTS: Among 59,426 Medicare beneficiaries, 918 had diagnosed RA. Compared to the first quartile, increased distance was associated with decreased odds of RA diagnosis (odds ratio [OR] 0.96 [95% confidence interval (95% CI) 0.80-1.16] in second quartile, OR 0.88 [95% CI 0.72-1.07] in third quartile, and OR 0.72 [95% CI 0.56-0.93] in fourth quartile; P < 0.01 for trend). Similar results were observed using predefined categories. Among those with RA, increased distance was associated with increased odds of DMARD receipt across quartiles (OR 1.15 [95% CI 1.06-1.25] in second quartile, OR 1.41 [95% CI 1.29-1.54] in third quartile, and OR 1.32 [95% CI 1.18-1.46] in fourth quartile; P = 0.001 for trend). There was no relationship between predefined categories and DMARD receipt (P = 0.45 for trend). CONCLUSION: Increased driving distance to rheumatologists was associated with decreased odds of RA diagnosis. Among those with diagnosed RA, the odds of DMARD receipt rose as distance increased from <2 to 16 miles, but not beyond. Urban residents living closer to rheumatologists may have barriers to DMARD use besides geographic access.

Predictors of stopping and starting disease-modifying antirheumatic drugs for rheumatoid arthritis.

OBJECTIVE: Disease-modifying antirheumatic drugs (DMARDs) are the standard of care for rheumatoid arthritis (RA); however, studies have found that many patients do not receive them. We examined predictors of starting and stopping DMARDs among a longitudinal cohort of patients with RA. METHODS: Study participants came from a cohort of RA patients recruited from a random sample of rheumatologists' practices in Northern California. We examined patterns and predictors of stopping and starting nonbiologic and biologic DMARDs during 1982-2009 based on annual questionnaires. Stopping was defined as stopping all DMARDs and starting was defined as transitioning from no DMARDs to any DMARDs across 2 consecutive years. RESULTS: The analysis of starting DMARDs included 471 subjects with 1,974 pairs of years with no DMARD use in the first of 2 consecutive years. From this population, subjects started DMARD use by year 2 in 313 (15.9%) of the pairs. The analysis of stopping DMARDs included 1,026 subjects with 7,595 pairs of years with DMARD use in the first of 2 consecutive years; in 423 pairs (5.6%), subjects stopped DMARD use by year 2. In models that adjusted for RA-related factors, sociodemographics, and comorbidities, significant predictors of starting DMARDs included younger age, Hispanic ethnicity, shorter disease duration, and the use of oral glucocorticoids. In separate adjusted models, predictors of stopping DMARDs included Hispanic ethnicity and low income, while younger age was associated with a reduced risk of stopping. CONCLUSION: Efforts to improve DMARD use should focus on patient age, ethnicity, and income and RA-related factors.

Sociodemographic, disease, health system, and contextual factors affecting the initiation of biologic agents in rheumatoid arthritis: a longitudinal study.

OBJECTIVE: To analyze the effect of sociodemographic, disease, and health system characteristics and contextual features about the community of residence on the subsequent initiation of treatment with biologic agents for rheumatoid arthritis (RA). METHODS: We analyzed data from the University of California, San Francisco Rheumatoid Arthritis Panel Study for the years 1999-2011. Principal data collection was by a structured annual phone survey. We estimated Kaplan-Meier curves of the time until initiation of biologic agents, stratified by age and income. We also used Cox regression to estimate the effect of individual-level sociodemographic and medical factors, contextual-level socioeconomic status measures, and density of health providers in the local community on the probability of initiating therapy with biologic agents for RA. RESULTS: In total, 527 persons were included in the panel in 1999, and 229 persons (44%) had initiated therapy with biologic agents by 2011. In multivariable Cox regression models, age <70 years (hazard ratio [HR] for ages 19-54 years 1.89 [95% confidence interval (95% CI) 1.24-2.87] and HR for ages 55-69 years 1.25 [95% CI 0.84-1.87]), Hispanic ethnicity (HR 2.02 [95% CI 1.05-3.86]), household income ≥$30,000/year (HR 1.61 [95% CI 1.12-2.32]), being married or with a partner (HR 1.39 [95% CI 1.00-1.92]), and residence in rural environments (HR 1.96 [95% CI 1.28-2.99]) were associated with a higher probability of initiating biologic agents. Having no (HR 0.18 [95% CI 0.08-0.40]) or only 1-4 rheumatology visits in the year prior to interview (HR 0.60 [95% CI 0.45-0.81]) and living in an area with ≥1 federally qualified health centers (HR 0.63 [95% CI 0.41-0.96]) were associated with a lower probability. CONCLUSION: The probability of initiating therapy with biologic agents is affected by sociodemographic and health system characteristics as well as the nature of the community of residence, resulting in disparities in access to these medications.

Changes in use of disease-modifying antirheumatic drugs for rheumatoid arthritis in the United States during 1983-2009.

OBJECTIVE: Use of nonbiologic disease-modifying antirheumatic drugs (DMARDs) and/or biologic DMARDs is generally recommended to improve the prognosis of patients with rheumatoid arthritis (RA). The objective of this study was to describe the changing trends in DMARD use for RA over the past 2 decades. METHODS: We analyzed data from an open longitudinal cohort of RA patients recruited from rheumatologists' practices in northern California. We examined baseline demographic and clinical characteristics of the participants and their long-term DMARD use through annual comprehensive structured telephone interviews. RESULTS: A total of 1,507 established RA patients were recruited through 5 enrollment periods between 1983 and 2009. Between 1983 and 2009, the use of any DMARD increased from 71% of all patients to 83% (P for trend < 0.0001). In 2009, 43% received a biologic DMARD, 34% were on both nonbiologic and biologic DMARDs, and 40% were treated with only nonbiologic DMARDs. The 4 most commonly used nonbiologic DMARDs in 2009 were methotrexate (49%), hydroxychloroquine (30%), leflunomide (13%), and sulfasalazine (7%). Etanercept (20%) was the most commonly used biologic DMARD in 2009, followed by infliximab (10%), adalimumab (9%), and abatacept (6%). Use of oral steroids was common (40-50%) and remained similar throughout the study period. CONCLUSION: There has been a significant increase in the use of DMARDs for RA over the past 2 decades. However, 15% of the individuals with a clinical diagnosis of RA were not receiving DMARDs in 2009. Future research should focus on sociodemographic and clinical factors associated with DMARD use for RA.

Quality of care in systemic lupus erythematosus: application of quality measures to understand gaps in care.

BACKGROUND: Systemic lupus erythematosus (SLE) affects 1 in 2500 Americans and is associated with significant morbidity and mortality. The recent development of SLE quality measures provides an opportunity to understand gaps in clinical care and to identify modifiable factors associated with variations in quality. OBJECTIVE: To evaluate performance on SLE quality measures as well as differences in quality of care by demographic, socioeconomic, disease, and health system characteristics. DESIGN AND PATIENTS: Cross-sectional analysis of data derived from the Lupus Outcomes Study, a prospective, longitudinal study of 814 individuals. Principal data collection was through annual structured telephone surveys between 2009-2010. Data on 13 SLE quality measures was collected. We used regression models to estimate demographic, socioeconomic, disease, and health system characteristics associated with performance on individual and overall quality measures. OUTCOME MEASURES: Performance on each quality measure and overall performance on all measures for which participants were eligible (pass rate). RESULTS: Participants were eligible for a mean of five measures (range 2-12). Performance varied from 29 % (assessment of cardiovascular risk factors) to 90 % (sun avoidance counseling). The overall pass rate was 65 % (95 % CI 64 %, 65 %). In unadjusted analyses, younger age, minority race/ethnicity, poverty, shorter disease duration, fewer physician visits, and lack of health insurance, were associated with lower pass rates. Receiving care in public sector managed care organizations was associated with higher pass rates. After adjustment, younger age, having fewer physician visits and lacking health insurance remained significantly associated with lower performance; receiving care in public sector managed care organizations remained associated with higher performance. CONCLUSIONS: We identified a number of gaps in clinical care for SLE. Factors associated with the health care system, including presence and type of health insurance, were the primary determinants of performance on quality measures in SLE.

Longitudinal study of the impact of incident organ manifestations and increased disease activity on work loss among persons with systemic lupus erythematosus.

OBJECTIVE: There is increasing evidence of the impact of systemic lupus erythematosus (SLE) on employment, but few studies have had sufficient sample size and longitudinal followup to estimate the impact of specific manifestations or of increasing disease activity on employment. METHODS: Data were derived from the University of California, San Francisco, Lupus Outcomes Study, a longitudinal cohort of 1,204 persons with SLE sampled between 2002 and 2009. Of the 1,204 persons, 484 were working at baseline and had at least 1 followup interview. We used the Kaplan-Meier method to estimate the time between onset of thrombotic, neuropsychiatric, or musculoskeletal manifestations, or of increased disease activity, and work loss. We used Cox proportional hazards regression to estimate the risk of work loss associated with the onset of specific manifestations, the number of manifestations, and increased activity, with and without adjustment for sociodemographic, employment, and SLE duration characteristics. RESULTS: By 4 years of followup, 57%, 34%, and 38% of those with thrombotic, musculoskeletal, and neuropsychiatric manifestations, respectively, had stopped working, as had 42% of those with increased disease activity. On a bivariable basis, the risk of work loss was significantly higher among persons ages 55-64 years and those with increased disease activity and each kind of manifestation. In multivariable analysis, older age, shorter job tenure, thrombotic and musculoskeletal manifestations, greater number of manifestations, and high levels of activity increased the risk of work loss. CONCLUSION: Incident thrombosis and musculoskeletal manifestations, multiple manifestations, and increased disease activity are associated with the risk of work loss in SLE.

Cardiovascular and disease-related predictors of depression in systemic lupus erythematosus.

OBJECTIVE: Depression and cardiovascular disease are common and debilitating comorbidities associated with systemic lupus erythematosus (SLE). In this study, history of cardiovascular events, cardiovascular risk factors, and SLE disease-related factors were evaluated as longitudinal predictors of depression in a large cohort of patients with SLE. METHODS: Data were derived from 663 adult participants in the 2004-2008 Lupus Outcomes Study, who were followed for up to 5 annual interviews. Multivariate logistic regression analyses using generalized estimating equations were used to determine predictors of the development of increased depressive symptom severity over a 12-month period (Center for Epidemiologic Studies Depression Scale [CES-D] score of 23 or greater), yielding 2,224 paired observations. Predictors included sociodemographics, traditional cardiovascular risk factors (reported presence of heart disease, history of stroke or myocardial infarction, hypertension, hypercholesterolemia, diabetes mellitus, obesity, smoking status, and family history), and SLE-specific risk factors (glucocorticoid use, renal involvement, disease duration, and disease activity). RESULTS: The annual incidence of depression was 12% in this cohort. Multivariate predictors of new-onset depression included younger age (ages 20-39 years: odds ratio [OR] 2.3, 95% confidence interval [95% CI] 1.3-3.9; ages 40-59 years: OR 1.8, 95% CI 1.1-2.7), Hispanic/Latino ethnicity (OR 1.8, 95% CI 1.2-2.8), having some college education (OR 1.8, 95% CI 1.1-3.0), baseline CES-D score (OR per point 1.1, 95% CI 1.1-1.2), presence of diabetes mellitus (OR 1.8, 95% CI 1.1-2.8), and baseline SLE disease activity (OR 1.2, 95% CI 1.1-1.4). CONCLUSION: These results suggest that, in addition to known sociodemographic factors, the presence of diabetes mellitus and SLE disease activity may play a role in the development of depression in SLE.

Using the Center for Epidemiologic Studies Depression Scale to screen for depression in systemic lupus erythematosus.

OBJECTIVE: Identifying persons with systemic lupus erythematosus (SLE) at risk for depression would facilitate the identification and treatment of an important comorbidity conferring additional risk for poor outcomes. The purpose of this study was to determine the utility of a brief screening measure, the Center for Epidemiologic Studies Depression Scale (CES-D), in detecting mood disorders in persons with SLE. METHODS: This cross-sectional study examined 150 persons with SLE. Screening cut points were empirically derived using threshold selection methods, and receiver operating characteristic curves were estimated. The empirically derived cut points of the CES-D were used as the screening measures and were compared to other commonly used CES-D cut points in addition to other commonly used methods to screen for depression. Diagnoses of major depressive disorder or other mood disorders were determined using a "gold standard" structured clinical interview. RESULTS: Of the 150 persons with SLE, 26% of subjects met criteria for any mood disorder and 17% met criteria for major depressive disorder. Optimal threshold estimations suggested a CES-D cut score of 24 and above, which yielded adequate sensitivity and specificity in detecting major depressive disorder (88% and 93%, respectively) and correctly classified 92% of participants. To detect the presence of any mood disorder, a cut score of 20 and above was suggested, yielding sensitivity and specificity of 87% and correctly classifying 87%. CONCLUSION: These results suggest the CES-D may be a useful screening measure to identify patients at risk for depression.

A randomized trial of a multifaceted intervention to reduce falls among community-dwelling adults.

Using a randomized controlled trial, we tested the efficacy of a fall prevention intervention to reduce falls among adults in a community-based health promotion program. Adults aged 65 and older within two counties were recruited (control n = 257; intervention n = 286). After 12 months, there was a significant decrease in the number of falls in both groups (odds ratio = 0.45, p < .04), but the time by group membership interaction was not significant (χ(2) = 0.15, p < .69). Multivariate analysis did not find significant differences between the control and intervention groups for physical function as measured by a balance test or a sitting/standing test. Further research is needed on effective methods to deliver multifaceted fall interventions to older adults who are already being served by community health promotion programs.
