Real-world treatment patterns in patients with systemic lupus erythematosus: associations with comorbidities and damage. Lupus Sci Med 2024; 11:e001266. [PMID: 39317452 PMCID: PMC11423723 DOI: 10.1136/lupus-2024-001266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Accepted: 09/15/2024] [Indexed: 09/26/2024]
Abstract
OBJECTIVE To assess treatment patterns and the association between long-term glucocorticoid (GC) and hydroxychloroquine (HCQ) use and damage accrual in patients with systemic lupus erythematosus (SLE). METHODS A retrospective study including patients with SLE using the computerised database of a large health maintenance organisation. Patients were matched with subjects from the general population. Multivariable logistic regression models were used to assess the association between GC cumulative daily doses, HCQ and comorbidities: Osteoporosis, cardiovascular disease (CVD), hypertension and diabetes mellitus. Models were adjusted for age, sex, socioeconomic status, smoking, disease duration and HCQ use. RESULTS A total of 1073 patients with SLE were included, 87.79% were women. The age at first diagnosis was 37.23±14.36 and the SLE disease duration was 12.89±6.23 years. Initiation of HCQ within 12 months of SLE diagnosis increased from 51.02% in 2000 to 83.67% in 2010 and 93.02% in 2018. The annual usage of GC gradually decreased from 45.34% in 2000 to 30.76% in 2020. CVD and osteoporosis were more prevalent in SLE than in the general population. Multivariable logistic regression models revealed increased odds for comorbidities in patients receiving a mean daily dose of prednisone of more than 5 mg/day compared with those receiving 5 mg/day or less. CONCLUSIONS CVD and osteoporosis were more prevalent in SLE than in the general population. The dose and frequency of GC treatment in patients with SLE have decreased over the years. Prednisone usage in doses exceeding 5 mg/day is associated with significantly increased odds of osteoporosis and CVD.

Clin Rheumatol 2024; 43:2843-2856. [PMID: 38997544 PMCID: PMC11330408 DOI: 10.1007/s10067-024-07059-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2024] [Revised: 06/05/2024] [Accepted: 07/04/2024] [Indexed: 07/14/2024]
Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease with an unsatisfactory state of treatment. We aim to explore novel targets for SLE from a genetic standpoint. METHODS Cis-expression quantitative trait loci (eQTLs) for whole blood from 31,684 samples provided by the eQTLGen Consortium as well as two large SLE cohorts were utilized for screening and validating genes causally associated with SLE. Colocalization analysis was employed to further investigate whether changes in the expression of risk genes, as indicated by GWAS signals, influence the occurrence and development of SLE. Targets identified for drug development were evaluated for potential side effects using a phenome-wide association study (PheWAS). Based on the multiple databases, we explored the interactions between drugs and genes for drug prediction and the assessment of current medications. RESULTS The analysis comprised 5427 druggable genes in total. The two-sample Mendelian randomization (MR) in the discovery phase identified 20 genes causally associated with SLE and validated 8 genes in the replication phase. Colocalization analysis ultimately identified five genes (BLK, HIST1H3H, HSPA1A, IL12A, NEU1) with PPH4 > 0.8. PheWAS further indicated that drugs acting on BLK and IL12A are less likely to have potential side effects, while HSPA1A and NEU1 were associated with other traits. Four genes (BLK, HSPA1A, IL12A, NEU1) have been targeted for drug development in autoimmune diseases and other conditions. CONCLUSIONS .This study identified five genes as therapeutic targets for SLE. Repurposing and developing drugs targeting these genes is anticipated to improve the existing treatment state for SLE. Key Points • We identified five gene targets of priority for the treatment of SLE, with BLK and IL12A indicating fewer side effects. • Among the existing drugs that target these candidate genes, Ustekinumab, Ebdarokimab, and Briakinumab (targeting the IL12 gene) and CD24FC (targeting HSPA1A) may potentially be repurposed for the treatment of SLE.

Healthcare resource utilization and costs in patients with a newly confirmed diagnosis of lupus nephritis in the United States over a 5-year follow-up period. BMC Health Serv Res 2024; 24:691. [PMID: 38822336 PMCID: PMC11143616 DOI: 10.1186/s12913-024-11060-6] [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: 03/12/2024] [Accepted: 04/29/2024] [Indexed: 06/02/2024] Open
Abstract
BACKGROUND We aimed to describe healthcare resource utilization (HCRU) and healthcare costs in patients with newly confirmed lupus nephritis (LN) in the United States over a 5-year follow-up period. METHODS This retrospective, longitudinal cohort study (GSK Study 214102) utilized administrative claims data to identify individuals with a newly confirmed diagnosis of LN between August 01, 2011, and July 31, 2018, based on LN-specific International Classification of Diseases diagnosis codes. Index was the date of first LN-related diagnosis code claim. HCRU, healthcare costs, and incidence of systemic lupus erythematosus (SLE) flares were reported annually among eligible patients with at least 5 years continuous enrollment post-index. RESULTS Of 2,159 patients with a newly confirmed diagnosis of LN meeting inclusion and exclusion criteria, 335 had at least 5 years continuous enrollment post-index. HCRU was greatest in the first year post-LN diagnosis across all categories (inpatient admission, emergency room [ER] visits, ambulatory visits, and pharmacy use), and trended lower, though remained substantial, in the 5-year follow-up period. Among patients with LN and HCRU, the mean (standard deviation [SD]) number of ER visits and inpatient admissions were 3.7 (4.6) and 1.8 (1.5), respectively, in Year 1, which generally remained stable in Years 2-5; the mean (SD) number of ambulatory visits and pharmacy fills were 35.8 (25.1) and 62.9 (43.8), respectively, in Year 1, and remained similar for Years 2-5. Most patients (≥ 91.6%) had ≥ 1 SLE flare in each of the 5 years of follow-up. The proportion of patients who experienced a severe SLE flare was higher in Year 1 (31.6%) than subsequent years (14.3-18.5%). Total costs (medical and pharmacy; mean [SD]) were higher in Year 1 ($44,205 [71,532]) than subsequent years ($29,444 [52,310]-$32,222 [58,216]), driven mainly by inpatient admissions (Year 1: $21,181 [58,886]; subsequent years: $7,406 [23,331]-$9,389 [29,283]). CONCLUSIONS Patients with a newly confirmed diagnosis of LN have substantial HCRU and healthcare costs, particularly in the year post-diagnosis, largely driven by inpatient costs. This highlights the need for improved disease management to prevent renal damage, improve patient outcomes, and reduce costs among patients with renal involvement.

Remission and low disease activity are associated with lower healthcare costs: results from the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort. Ann Rheum Dis 2024:ard-2024-225613. [PMID: 38754981 DOI: 10.1136/ard-2024-225613] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 04/30/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVES This study aims to determine the independent impact of definitions of remission/low disease activity (LDA) on direct/indirect costs (DCs, ICs) in a multicentre inception cohort. METHODS Patients from 31 centres in 10 countries were enrolled within 15 months of diagnosis and assessed annually. Five mutually exclusive disease activity states (DAS) were defined as (1) remission off-treatment: clinical (c) SLEDAI-2K=0, without prednisone/immunosuppressants; (2) remission on-treatment: cSLEDAI-2K=0, prednisone ≤5 mg/day and/or maintenance immunosuppressants; (3) LDA-Toronto Cohort (TC): cSLEDAI-2K≤2, without prednisone/immunosuppressants; (4) modified lupus LDA state (mLLDAS): SLEDAI-2K≤4, no activity in major organs/systems, no new activity, prednisone ≤7.5 mg/day and/or maintenance immunosuppressants and (5) active: all remaining assessments.At each assessment, patients were stratified into the most stringent DAS fulfilled and the proportion of time in a DAS since cohort entry was determined. Annual DCs/ICs (2021 Canadian dollars) were based on healthcare use and lost workforce/non-workforce productivity over the preceding year.The association between the proportion of time in a DAS and annual DC/IC was examined through multivariable random-effects linear regressions. RESULTS 1692 patients were followed a mean of 9.7 years; 49.0% of assessments were active. Remission/LDA (per 25% increase in time in a remission/LDA state vs active) were associated with lower annual DC/IC: remission off-treatment (DC -$C1372; IC -$C2507), remission on-treatment (DC -$C973; IC -$C2604,) LDA-TC (DC -$C1158) and mLLDAS (DC -$C1040). There were no cost differences between remission/LDA states. CONCLUSIONS Our data suggest that systemic lupus erythematosus patients who achieve remission, both off and on-therapy, and reductions in disease activity incur lower costs than those experiencing persistent disease activity.

Abstract
AIMS Our study aims to provide an enhanced comprehension of systemic lupus erythematosus (SLE) burden in United Arab Emirates (UAE), over a five-year period from payer and societal perspective. MATERIALS AND METHODS A Markov model was established to simulate the economic consequences of SLE among UAE population. It included four health states: i) the three phenotypes of SLE, representing mild, moderate, and severe states, and ii) death. Clinical parameters were retrieved from previous literature and validated using the Delphi panel-the most common clinical practice within the Emirati healthcare system. We calculated the disease management, transient events, and indirect costs by macro costing. One-way sensitivity analysis was conducted. RESULTS The estimated number of SLE patients in our study was 13,359. The number of SLE patients with mild, moderate, and severe phenotypes was 3,914, 8,109, and 1,336, respectively. Disease management costs, including treatment of each phenotype and disease follow-up, were AED 2 billion ($0.89 billion), whereas the costs of transient events (infections, flares, and consequences of SLE-related organ damage) were AED 1 billion ($0.44 billion). The productivity loss costs among adult-employed patients with SLE in the UAE were estimated at AED 7 billion ($3.1 billion). The total SLE cost over five years from payer and societal perspectives is estimated at AED 3 ($1.3 billion) and 10 billion ($4.4 billion), respectively. Additionally, the costs per patient per year from the payer and societal perspectives were AED 45,960 ($20,610) and AED 148,468 ($66,578), respectively. CONCLUSION Our findings demonstrate that the burden of SLE in the UAE is enormous, mainly because of the costly complications and productivity loss. More awareness should be created to limit the progression of SLE and reduce the occurrence of flares, necessitating further economic evaluations of novel treatments that could help reduce the economic consequences of SLE in the UAE.

Abstract
INTRODUCTION Our cost-of-illness (COI) model adopted the perspective of both payer and society over a time horizon of 5 years to measure the economic burden of systemic lupus erythematosus (SLE) in Malaysia. METHODOLOGY Our COI model utilized a prevalence-based model to estimate the costs and economic consequences of SLE in Malaysia. The clinical parameters were obtained from published literature and validated using the Delphi panel. Direct and indirect medical costs were measured, including disease management, transient events, and indirect costs. One-way sensitivity analysis was also performed. RESULTS The number of target Malaysian patients with SLE in the COI model was 18,121. At diagnosis, the numbers of SLE patients with mild, moderate, and severe phenotypes were 2,582, 13,897, and 1,642, respectively. The total SLE cost in Malaysia over 5 years from both payer and society perspectives was estimated at MYR 678 million and 2 billion, respectively. The results showed a considerable cost burden due to productivity losses resulting from SLE-related morbidity and mortality. Over a 5-year time horizon, the costs per patient per year from the payer and society perspectives were MYR 7,484 ($4766) and 24,281($15,465), respectively. CONCLUSION Our study demonstrated the substantial economic burden of SLE in Malaysia over a time horizon of 5 years. It affects adults of working age, in addition to the costs of SLE management and its consequences, such as flares, infection, and organ damage. Our COI model indicated that disease management costs among patients with higher disease severity were higher than those among patients with a mild phenotype. Hence, more attetion should be paid to limiting the progression of SLE and the occurrence of flares, with the need for further economic evaluation of novel treatments that could lead to better outcomes.

Abstract
AIM This study aimed to obtain estimates for the direct medical charges associated with hospitalizations and emergency department visits of validated SLE cases in a diverse Systemic Lupus Erythematosus (SLE) population. METHODS The Georgians Organized Against Lupus (GOAL) cohort is a population-based cohort of adult SLE patients from metropolitan Atlanta, GA USA, an area having a diverse SLE population. The GOAL cohort aims to study the impact of social determinants of health (SDoH) on outcomes relevant to patients, healthcare providers, and policymakers. For this study, survey data collected during 2011-2012 was linked to the Georgia Hospital Discharge Database (HDD) to capture hospital admissions (HAs) and emergency department visits (EDVs) throughout Georgia from 2012 through 2013. Direct medical charges were summarized by HCU type among all patients, among those with actual visits, and by socio-demographics and healthcare factors. RESULTS Among 829 patients (94% women, 78% Black, 64% non-private insurance, 64% not-employed, mean age of 46), 170 (20.5%) and 300 (36.2%) participants had at least one HA and one EDV in 1-year of follow-up, respectively, with 111(13.4%) having both HA and EDV. On average, each patient experienced 0.38 HAs and 0.91 EDVs, with per-patient direct medical charges of $14,968 for HAs & $3,022 for EDVs, and $39,645 per HA & $3,305 per EDV. Patients with higher social vulnerability or more severe disease had higher charges for both HA and EDV (p < 0.01), likely due to the delayed care and neglected health needs leading to more advanced and costly medical treatments. Living below the federal poverty level was associated with higher charges for EDVs (p < 0.001) but with lower charges for HAs (p = 0.036). CONCLUSIONS This study underscores the economic burden of SLE on vulnerable populations, emphasizing the importance of including socio-economic factors in healthcare planning. Policy efforts should prioritize reducing disparities in access to care and implementing preventive strategies.

Abstract
OBJECTIVE Comparison of oral corticosteroid (OCS) use in patients with SLE in a US rheumatology network pre- and post-belimumab initiation. METHODS This retrospective cohort study (GSK Study 214140) used data from the Patient-Important Outcomes Data Repository (PIONEER)-Rheumatology database. Eligible adults with SLE initiated belimumab between 1 January 2012 and 30 June 2021, and had available data for >180 days pre- and >360 days post-belimumab initiation. The index was the date of belimumab initiation. Changes in OCS use were measured by: proportion of patients receiving OCS; mean total OCS dose/patient; mean total number of OCS days supplied/patient; mean daily OCS dose for days supplied/patient; the proportion of patients with OCS doses of ≤5 mg/day and ≤7.5 mg/day for days supplied. These changes were assessed between period (P)1 (6 months pre-index) and P2 (first 6 months post-index) and P3 (second 6 months post-index) in patients with OCS use in P1 who persisted with belimumab at each assessed period. RESULTS Overall, 608 patients received belimumab for 180 days (full analysis set (FAS)) and 492 for 360 days. Most patients were female (92.8%); 70.4% had moderate SLE. In P1, 56.3% of FAS patients and 54.5% of patients who persisted with belimumab for 360 days received OCS.Among patients receiving OCS in P1, significantly fewer patients received OCS in P2 (78.4%) and P3 (64.9%) vs P1 (100.0%). Significant reductions from P1 were observed in P2 and P3 in the mean total OCS dose/patient, the mean OCS daily dose for days supplied and the proportions of patients with OCS dose of ≤5 mg/day and ≤7.5 mg/day, and the mean total OCS days supplied/patient in P3 only. CONCLUSIONS This analysis showed significant reductions in OCS dose and use in patients with SLE who persisted with belimumab, providing more real-world evidence for belimumab's steroid-sparing effect.

Abstract
OBJECTIVE The aim is to analyze health care resource utilization (HCRU) of patients with lupus (SLE) from a health management organization (HMO) in Buenos Aires, Argentina, compared with matched controls and comparing periods of flare, low disease activity, and remission. METHODS This is a retrospective observational study including all SLE incident cases (ACR 1997/SLICC 2012 criteria) between 2000 and 2020 and 5 matched controls. Clinical data and HCRU (medical and nonmedical consultations, lab and imaging tests performed, emergency room visits, hospitalizations, and drugs prescribed) were obtained from administrative databases and electronic medical records. For each patient with SLE, an activity state was determined in every month of follow-up: flare (BILAG A or 2 BILAG B); low disease activity (LLDAS); remission (DORIS definition); or intermediate activity (not fulfilling any of previous). Incidence rates for each HCRU item and incidence rate ratios between SLE and control patients were and between remission and flare periods were calculated. Multivariate negative binomial logistic regression analyses were performed for identification of variables associated with major resource use. RESULTS A total of 62 SLE and 310 control patients were included, 88.7% were women, the median age at diagnosis was 46 years, and were followed for more than 8 years. Patients with SLE contributed with 537.2 patient-years (CI 95% 461.1-613.3) and controls with 2761.9 patient-years (CI 95% 2600.9-2922.8). HCRU in patients with SLE was significantly higher than in controls in all items, even in remission periods. Patients with SLE remained 74.4% of the time in remission, 12.1% in LLDAS, 12.2% in intermediate activity, and 1.3% in flare (there were 64 flares in 36 patients). HCRU was significantly higher during flare periods compared with remission periods. Number of flares was independently associated with emergency department consultations, lab tests and X-ray performed, number of drugs prescribed, and hospitalizations. CONCLUSION Significantly more HCRU was observed in patients with SLE in flare compared to remission periods.

Abstract
BACKGROUND/OBJECTIVE Although the high disease burden associated with eosinophilic granulomatosis with polyangiitis (EGPA) has been established, the disease burden in patients initiating mepolizumab in real-world practice is poorly understood. This study aimed to assess characteristics and burden of real-world patients with EGPA initiating mepolizumab. METHODS This was a database study (GSK study ID: 214156) of US patients (≥12 years old) with EGPA and ≥1 mepolizumab claim (index date) identified from the Merative MarketScan Commercial and Medicare Supplemental Databases (November 1, 2015, to March 31, 2020). Outcomes assessed in the 12-month baseline period before index (inclusive) included patient characteristics, treatment use, EGPA relapses, asthma exacerbations, health care resource utilization, and costs. RESULTS In the 103 patients included (mean age, 51.1 years; 63.1% female), the most common manifestations were asthma (89.3%), chronic sinusitis (57.3%), and allergic rhinitis (43.7%). In total, 91.3% of patients had ≥1 oral corticosteroid (OCS) claim (median dose, 7.4 mg/d prednisone-equivalent), 45.6% were chronic OCS users (≥10 mg/d during the 90 days preindex), 99.0% had ≥1 EGPA-related relapse, and 62.1% ≥1 asthma exacerbation. During the baseline period, 26.2% and 97.1% of patients had EGPA-related inpatient admissions and office visits, respectively. Median all-cause total health care costs per patient were $33,298, with total outpatient costs ($16,452) representing the largest driver. CONCLUSIONS Before initiating mepolizumab, a substantial real-world EGPA disease burden is evident for patients, with resulting impact on health care systems, and indicative of unmet medical needs. Mepolizumab treatment, with a demonstrated positive clinical benefit-risk profile may represent a useful treatment option for reducing EGPA disease burden.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) patients are prone to frequent emergency department (ED) visits. This study explores the epidemiology and outcomes of ED visits by patients with SLE utilizing the Nationwide Emergency Department Sample (NEDS). METHODS Using NEDS (2019), SLE ED visits identified using ICD-10 codes (M32. xx) were compared with non-SLE ED visits in terms of demographic and clinical features and primary diagnoses associated with the ED visits. Factors associated with inpatient admission were analyzed using logistic regression. Variations in ED visits by age and race were assessed. RESULTS We identified 414,139 (0.35%) ED visits for adults ≥ 18 years with SLE. ED visits with SLE comprised more women, Black patients, ages 31-50 years, Medicare as the primary payer, and had higher comorbidity burden. A greater proportion of Black and Hispanic SLE patients who visited the ED were in the youngest age category of 18-30 years (around 20%) compared to White patients (less than 10%). Non-White patients had higher Medicaid utilization (27%-32% vs 19% in White patients). Comorbidity patterns varied based on race, with more White patients having higher rates of hyperlipidemia and ischemic heart disease (IHD) and more Black patients having chronic kidney disease (CKD), hypertension, and heart failure. Categorizing by race, SLE/connective tissue disease (CTD) and infection were the most prevalent primary ED diagnosis in non-White and White patients, respectively. Age ≥ 65 years, male sex, and comorbidities were linked to a higher risk of admission. Black race (OR 0.86, p = .01) and lowest income quartile (OR 0.78, p = .003) had lower odds of inpatient admission. CONCLUSION Infection and SLE/CTD were among the top diagnoses associated with ED visits and inpatient admission. Despite comprising a significant proportion of SLE ED visits, Black patients had lower odds of admission. While the higher prevalence of older age groups, hyperlipidemia, and IHD among White patients may partly explain the disparate results, and further study is needed to understand the role of other factors including reliance on the ED for routine care compared among Black patients, differences in insurance coverage, and potential socioeconomic biases among healthcare providers.

Abstract
Rheumatic diseases are a group of chronic conditions that are associated with significant morbidity, impaired physical function, psychosocial stress, and cost to the healthcare system. Peer support interventions have been shown to have a positive impact on health outcomes in several chronic conditions, but no review has specifically assessed the impact of peer support on rheumatic conditions. The aim of this narrative literature review was to understand how peer support has been applied in the field of rheumatology, with a specific focus on the impact of observational and randomized studies of direct peer support interventions on various outcome measures across rheumatic conditions. We also examined studies exploring patient attitudes and preferences toward peer support. The majority of studies included focused on peer support in rheumatoid arthritis and systemic lupus erythematosus. Generally, patients across the spectrum of rheumatic disease perceive peer support as a useful tool. Peer support interventions, while highly variable, were generally associated with positive impacts on health-related quality of life metrics (both perceived and measured), although these differences were not always statistically significant. Important limitations include variability in study design, selection bias among study participants, and short follow-up periods across most peer support interventions.

Abstract
INTRODUCTION This analysis was conducted to assess the incidence of adverse clinical outcomes, healthcare resource use (HCRU), and the costs associated with systemic corticosteroid (SCS) use in adults with systemic lupus erythematosus (SLE) in the UK. METHODS We identified incident SLE cases using the Clinical Practice Research Datalink GOLD, Hospital Episode Statistics-linked healthcare, and Office for National Statistics mortality databases from January 1, 2005, to June 30, 2019. Adverse clinical outcomes, HCRU, and costs were captured for patients with and without prescribed SCS. RESULTS Of 715 patients, 301 (42%) had initiated SCS use (mean [standard deviation (SD)] 3.2 [6.0] mg/day) and 414 (58%) had no recorded SCS use post-SLE diagnosis. Cumulative incidence of any adverse clinical outcome over 10-year follow-up was 50% (SCS group) and 22% (non-SCS group), with osteoporosis diagnosis/fracture most frequently reported. SCS exposure in the past 90 days was associated with an adjusted hazard ratio of 2.41 (95% confidence interval 1.77-3.26) for any adverse clinical outcome, with increased hazard for osteoporosis diagnosis/fracture (5.26, 3.61-7.65) and myocardial infarction (4.52, 1.16-17.71). Compared to low-dose SCS (< 7.5 mg/day), patients on high-dose SCS (≥ 7.5 mg/day) had increased hazard for myocardial infarction (14.93, 2.71-82.31), heart failure (9.32, 2.45-35.43), osteoporosis diagnosis/fracture (5.14, 2.82-9.37), and type 2 diabetes (4.02 1.13-14.27). Each additional year of SCS use was associated with increased hazard for any adverse clinical outcome (1.15, 1.05-1.27). HCRU and costs were greater for SCS users than non-SCS users. CONCLUSIONS Among patients with SLE, there is a higher burden of adverse clinical outcomes and greater HCRU in SCS versus non-SCS users.

Abstract
OBJECTIVE To investigate the association of medication copayment and treatment adherence to hydroxychloroquine and immunosuppressants for SLE. METHODS We conducted a retrospective analysis of health claims data using Optum's de-identified Clinformatics Data Mart Database. Individuals with SLE continuously enrolled for 180 days from 1 July 2010 to 31 December 2019 were included. Adherence was defined as the proportion of days covered ≥80%. Copayment for a 30-day supply of medication was dichotomised as high (≥$10) or low (<$10). We examined the association between copayment and odds of adherence in multivariable-adjusted logistic regression models, including age, sex, race or ethnicity, comorbidities, educational attainment and household income. RESULTS We identified 12 510 individuals (age 54.2±15.5 years; 88.2% female sex), of whom 9510 (76%) were prescribed hydroxychloroquine and 1880 (15%) prescribed hydroxychloroquine and an additional immunosuppressant (azathioprine, methotrexate or mycophenolate mofetil). Median (IQR) 30-day copayments were $8 (4-10) for hydroxychloroquine, $7 (2-10) for azathioprine, $8 (3-11) for methotrexate and $10 (5-20) for mycophenolate mofetil. High copayments were associated with OR of adherence of 0.61 (95% CI 0.55 to 0.68) for hydroxychloroquine, OR 0.44 (95% CI 0.30 to 0.66) for azathioprine and OR 0.69 (95% CI 0.49 to 0.96) for mycophenolate mofetil. For methotrexate, the association was not significant. CONCLUSION In a large, administrative health claims database, we identified that high copayments were associated with reduced adherence to commonly prescribed medications for SLE. Incorporating awareness of the burden of copayments and its consequences into healthcare is essential to promote optimal medication adherence.

Abstract
BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease affecting as many as 322,000 people in the United States. Because of heterogeneity in both disease course and clinical manifestations, it is critical to identify a prevalent SLE population that includes patients with moderate or severe disease. Additionally, differences in the clinical and economic burden of SLE may exist across payer channels, yet to date this has not been reported in any previous studies. OBJECTIVE: To characterize the clinical and economic burden of SLE across disease severity and payer channels. METHODS: This retrospective study included patients from Merative MarketScan Commercial, Medicare Supplemental, and Medicaid databases from 2013 to 2020 (Commercial/Medicare) or 2013 to 2019 (Medicaid), with at least 1 inpatient or at least 2 outpatient SLE claims and no invalid steroid claims. The index date was a random SLE claim with at least 12 months of disease history. Patients were continuously enrolled 1 year pre-index (baseline) and 1 year post-index and classified with mild, moderate, or severe disease using a published algorithm. Baseline demographics, clinical characteristics, flares, and utilization/costs were compared across disease severity. RESULTS: 22,385 Commercial, 2,035 Medicare, and 8,083 Medicaid patients had SLE. Most Medicaid patients (51.1%) had severe disease. Comorbidity scores increased with disease severity (P < 0.001). 30.7% of Commercial, 34.1% Medicare, and 51.3% Medicaid patients had opioids, which increased with disease severity (P < 0.001). All-cause costs ranged from 1.8- to 2.3-fold for moderate vs mild and 4.2- to 6.5-fold for severe vs mild. Outpatient medical costs accounted for the highest proportion of all-cause costs, except Medicaid patients with severe disease, for whom inpatient costs were highest. Mean (SD) SLE-related annual costs were $23,030 (43,304) vs $1,738 (4,427) in severe vs mild for Commercial, $12,264 (31,896) vs $2,024 (4,998) for Medicare, and $7,572 (27,719) vs $787 (3,797) for Medicaid (P < 0.001). For patients with severe disease in Medicaid, 16.5% and 60.1% had inpatient and emergency department (ED) visits, respectively, vs 10.3% and 26.5% Commercial vs 10.6% and 24.6% Medicare. Mean [SD] flares per year in the baseline period increased from 2.5 [1.7] in mild to 4.6 [1.9] in severe for Commercial, 3.2 [1.9] to 5.0 [2.1] for Medicare, and 2.0 [1.6] to 4.5 [2.0] for Medicaid. CONCLUSIONS: Patients with severe SLE experienced more comorbidities, flares, and utilization/costs. Outpatient costs were the largest driver of all-cause costs for Commercial and Medicare (and Medicaid for mild to moderate SLE). Medicaid beneficiaries had the highest rate of severe SLE, highest use of ED and inpatient services, and highest oral corticosteroid and opioid use but the lowest utilization of disease-modifying treatments. Results demonstrate an unmet need in SLE treatment, especially among patients with moderate to severe disease or Medicaid coverage. DISCLOSURES: This study was funded by AstraZeneca. Drs Wu and Bryant are current employees of AstraZeneca and may own stock and/or options. At the time of the study, Ms Perry and Mr Tkacz were employed by IBM Watson Health, which received funding from AstraZeneca to conduct this study.

Abstract
Falls are the leading cause of mortality and chronic disability in elderly adults. There are effective fall prevention interventions available. But only a fraction of the individuals with balance/dizziness problems are seeking timely help from the healthcare system. Current literature confirms the underutilization of healthcare services for the management of balance problems in adults, especially older adults. This review article explores factors associated with healthcare utilization as guided by the Andersen Healthcare Utilization Model, a framework frequently used to explore the factors leading to the use of health services. Age, sex, race/ethnicity, BMI, and comorbidities have been identified as some of the potential predisposing factors; socioeconomic status, health insurance, and access to primary care are the enabling and disabling factors; and severity of balance problem, perceived illness, and its impact on daily activities are the factors affecting need for care associated with healthcare utilization for balance or dizziness problems. Knowledge about these barriers can help direct efforts towards improved screening of vulnerable individuals, better access to care, and education regarding effective fall prevention interventions for those who are at risk for underutilization. This can aid in timely identification and management of balance problems, thereby reducing the incidence of falls.

Abstract
OBJECTIVE Frailty is a risk factor for adverse health in adults with SLE, including those <65 years. Emergency department (ED) utilisation is high in adults with SLE, but to our knowledge, whether frailty is associated with ED use is unknown. In a large administrative claims dataset, we assessed risk of ED utilisation among frail adults with SLE ≤65 years of age relative to non-frail adults ≤65 years of age with SLE. METHODS Using the MarketScan Medicaid subset from 2011 to 2015, we identified beneficiaries 18-65 years with SLE (≥3 SLE International Classification of Diseases, Ninth Revision codes ≥30 days apart). Comparators without a systemic rheumatic disease (SRD) were matched 4:1 on age and gender. Frailty status in 2011 was determined using two claims-based frailty indices (CFIs). We compared risk of recurrent ED utilisation among frail and non-frail beneficiaries with SLE using an extension of the Cox proportional hazard model for recurrent events data. RESULTS Of 2262 beneficiaries with SLE and 9048 non-SRD comparators, 28.8% and 11.6% were frail, respectively, according to both CFIs. Compared with non-frail beneficiaries with SLE, frail beneficiaries with SLE had significantly higher hazard of recurrent ED use (HR 1.75, 95% CI 1.48 to 2.08). CONCLUSION Frailty increased hazard of recurrent ED visits in frail adults ≤65 years of age with SLE relative to comparable non-frail adults with SLE. Frailty is a potential target for efforts to improve quality of care in SLE.

Clin Ther 2023; 45:619-626. [PMID: 37271712 DOI: 10.1016/j.clinthera.2023.04.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 02/07/2023] [Accepted: 04/23/2023] [Indexed: 06/06/2023]
Abstract
PURPOSE The goal of this study was to compare health care costs, health care resource utilization, and adverse events associated with sustained oral corticosteroid (OCS) use versus no OCS use in systemic lupus erythematosus. METHODS This retrospective cohort study used claims data (January 1, 2006-July 31, 2019) from patients with systemic lupus erythematosus aged ≥5 years with ≥24 months of continuous enrollment. Health care costs, health care resource utilization, and OCS-related adverse events were assessed. The sustained OCS cohort (defined as ≥12 months of continuous OCS use) was divided into exposure categories based on the number of 6-month classification periods with >5 mg/d OCS (0, 1-2, or 3-4). FINDINGS Of the 6234 patients in the sustained OCS use cohort, there were 1587 (25.5%) patients with 0 periods of >5 mg/d OCS use, 2087 (33.5%) patients with 1 to 2 periods of >5 mg/d OCS use, and 2560 (41.1%) patients with 3 to 4 periods of >5 mg/d OCS use; the no OCS use cohort included 7828 patients. Adjusted health care cost differences (95% CIs) were significantly greater for patients with 0, 1 to 2, and 3 to 4 periods of OCS use >5 mg/d versus the no OCS use cohort ($7774 [5426-10,223], $21,738 [18,898-25,321], and $30,119 [26,492-33,774], respectively). A higher proportion of patients in all OCS exposure categories required health care resource utilization (≥99.7% vs 93.4%) and experienced OCS-related adverse events (94.3%-96.8% vs 82.6%) versus the no OCS use cohort, with more periods of OCS use >5 mg/d associated with increased health care resource utilization and adverse events. IMPLICATIONS Sustained OCS use in systemic lupus erythematosus was associated with high economic burden, health care resource utilization, and OCS-related adverse events. These data highlight the need for health care providers to carefully consider OCS use in systemic lupus erythematosus.

Abstract
This study identified trends in hydroxychloroquine (HCQ) prescription and retinopathy screening in patients with systemic lupus erythematosus (SLE) according to clinical practice guidelines to minimise the risk of HCQ retinopathy. We used data from patients diagnosed with SLE between 2004 and 2019 from the National Health Insurance Service in Korea. To assess trends of daily dose per actual body weight (ABW), we performed an interrupted time-series analysis and identified effects after revision of guidelines. Among 38,973 patients with SLE, 28,415 (72.9%) were prescribed HCQ from 2004 to 2019. The proportion of patients using HCQ among SLE patients was 63% in 2004 and increased to 76% in 2019. The median daily dose per ABW for HCQ users decreased from 5.88 mg/kg in 2004 to 3.98 mg/kg in 2019, and from 5.45 mg/kg in 2005 to 4.17 mg/kg in 2019 for HCQ new users. The annual implementation rate of screening tests among HCQ new users increased from 3.5% in 2006 to 22.5% in 2019. Study results indicated that HCQ dosing management was adequate based on the revised guidelines. Although the implementation rate of retinal screening has increased, it is necessary to enhance awareness of retinal screening in clinical settings.

Abstract
BACKGROUND Lupus nephritis (LN) is among the most severe organ manifestations of systemic lupus erythematosus (SLE), affecting between 31% and 48% of patients, usually within five years of SLE diagnosis. SLE without LN is associated with a high economic burden on the healthcare system, and although data are limited, several studies have shown that SLE with LN could increase this burden. Aim: We aimed to compare the economic burden of LN versus SLE without LN among patients managed in routine clinical practices in the USA and describe the clinical course of these patients. MATERIALS AND METHODS This was a retrospective observational study of patients with commercial or Medicare Advantage health insurance. It included 2310 patients with LN and 2310 matched patients who had SLE without LN; each patient was followed for 12 months after diagnosis (the patient's index date). Outcome measures included healthcare resource utilization (HCRU), direct healthcare costs, and SLE clinical manifestations. Results: In all healthcare settings, the mean (SD) use of all-cause healthcare resources was significantly higher in the LN versus SLE without LN cohort, including the mean number of ambulatory visits (53.9 (55.1) vs 33.0 (26.0)), emergency room visits (2.9 (7.9) vs 1.6 (3.3)), inpatient stays (0.9 (1.5) vs 0.3 (0.8)), and pharmacy fills (65.0 (48.3) vs 51.2 (42.6)) (all p<0.001). Total all-cause costs per patient in the LN cohort were also significantly higher compared with the SLE without LN cohort ($50,975 (86,281) vs $26,262 (52,720), p<0.001), including costs for inpatient stays and outpatient visits. Clinically, a significantly higher proportion of patients with LN experienced moderate or severe SLE flares compared with the SLE without LN cohort (p<0.001), which may explain the difference in HCRU and healthcare costs. CONCLUSION All-cause HCRU and costs were higher for patients with LN than for matched patients with SLE without LN, highlighting the economic burden associated with LN.

Abstract
BACKGROUND: Prolonged, high-dose corticosteroid treatment for systemic lupus erythematosus (SLE) is associated with substantial health care costs, health care resource utilization (HCRU), and adverse events (AEs). OBJECTIVE: To compare all-cause health care costs, HCRU, and oral corticosteroid (OCS)-related AEs among patients with prevalent OCS use and patients without OCS use. METHODS: This retrospective, longitudinal cohort study (GSK study 214100) used claims data from the IQVIA Real-World Data Adjudicated Claims - US, IQVIA, Inc, database between January 1, 2006, and July 31, 2019, to identify patients with SLE. Patients with at least 1 OCS pharmacy claim during the study period and continuous OCS use during the 6-month pre-index (baseline) period (index date is the date of the first OCS claim following 6 months' continuous use) formed the "prevalent OCS use cohort." This cohort was subdivided based on the level of OCS exposure during the 12-month observation period, ie, the number of 6-month periods of greater than 5 mg/day OCS use (0, 1, or 2). Patients without OCS claims formed the "no OCS use cohort." All patients had continuous enrollment during the baseline and observation periods, had at least 1 inpatient or at least 2 outpatient SLE diagnosis codes during baseline, and were aged at least 5 years at index. A 2-part model, a generalized linear regression model with a negative binomial distribution, and a multivariate logistic regression model were used to compare health care costs, HCRU, and the odds of developing an OCS-related AE between cohorts, respectively. RESULTS: The no OCS use and prevalent OCS use cohorts included 21,517 and 16,209 patients, respectively. Adjusted health care cost differences (95% CI) were significantly lower for the no OCS use cohort vs all prevalent OCS use exposure categories ($5,439 [$4,537-$6,371] vs $17,856 [$16,368-$19,498]), driven by inpatient stays and outpatient visits; HCRU was also significantly lower (adjusted incidence rate ratios vs no OCS use cohort [95% CI]: 1.20 [1.16-1.23] vs 1.47 [1.41-1.52]). Health care costs and HCRU increased with increasing length of OCS exposure. OCS-related AEs occurred more frequently for all prevalent OCS use exposure categories vs the no OCS use cohort (odds ratio [95% CI]: 1.39 [1.25-1.55] vs 2.32 [2.02-2.68]), driven by hematologic/oncologic and immune system-related AEs. The mean (SD) average daily dose of OCS increased with increasing periods of prevalent OCS use (2.5 [1.3], 6.9 [31.1], and 34.6 [1,717.3] mg/day, respectively, for patients with 0, 1, and 2 periods of OCS use). CONCLUSIONS: Prevalent OCS use incurs a substantial clinical and economic burden, highlighting the need for restricted OCS doses and durations.

Annual Direct Cost and Cost-Drivers of Systemic Lupus Erythematosus: A Multi-Center Cross-Sectional Study from CSTAR Registry. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3522. [PMID: 36834216 PMCID: PMC9963905 DOI: 10.3390/ijerph20043522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 02/06/2023] [Accepted: 02/08/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND To estimate the annual direct costs and cost-drivers associated with systemic lupus erythematosus (SLE) patients in China. METHODS A multi-center, cross-sectional study was conducted based on the CSTAR registry. The information on demography and expenditures for outpatient and inpatient visits due to SLE were collected using online questionnaires. These patients' medical records were from the database of the Chinese Rheumatology Information System (CRIS). The average direct costs and 95% confidence interval were estimated using the bootstrap method with 1000 bootstrap samples by resampling with replacement. The cost-drivers were identified using multivariate regression models. RESULTS A total of 1778 SLE patients from 101 hospitals participated in our study, with 92.58% as females, a mean age of 33.8 years old, a median duration of SLE of 4.9 years, 63.8% in an active disease state, 77.3% with two organs or more damaged, and 8.3% using biologics as treatment. The average annual direct cost per patient was estimated at CNY 29,727, which approximates to 86% for direct medical costs. For moderate to severe disease activities, the use of biologics, hospitalization, treatment of moderate or high dose glucocorticoids, and peripheral vascular, cardiovascular, and/or renal system involvements were found to substantially increase the direct costs, while health insurance slightly decreased the direct costs of SLE. CONCLUSIONS This study provided reliable insight into financial pressures on individual SLE patients in China. The efforts focusing on preventing flare occurrences and limiting disease progression were recommended to further reduce the direct cost of SLE.

Abstract
INTRODUCTION This study aimed to describe the clinical burden, healthcare resource utilisation (HCRU) and healthcare costs for patients with systemic lupus erythematosus (SLE) in the 12-60 months preceding an end-stage kidney disease (ESKD) diagnosis in the USA. METHODS This retrospective observational study identified adult patients with SLE with newly diagnosed ESKD between 1 March 2012 and 31 December 2018 using administrative claims data. Clinical characteristics, mean all-cause HCRU (i.e. any HCRU visit and pharmacy fill) and total all-cause healthcare costs (comprising medical and pharmacy costs in 2019 US dollars) were assessed during the 12 months pre-ESKD diagnosis and yearly during the 5 years pre-ESKD diagnosis among patients with ≥ 5 years of continuous health plan enrolment. RESULTS Of the 1356 patients included, 51.2% had severe SLE, 71.2% had lupus nephritis (LN) and 20.6% underwent kidney biopsy during the 12 months pre-ESKD. The mean (standard deviation [SD]) number of HCRU visits during the 12 months pre-ESKD was 78.0 (64.1) per patient. The mean (SD) total healthcare costs per patient in the 12 months pre-ESKD diagnosis was $64,887 (106,822), driven by medical costs $51,764 (96,458). The proportions of patients with severe SLE, LN and those undergoing biopsy increased from year 5 to year 1 pre-ESKD diagnosis. The mean (SD) number of HCRU visits increased from year 5 (61.6 [54.0]) to year 1 (83.2 [62.1]) pre-ESKD. Mean (SD) total healthcare costs rose year on year from year 5 ($34,890 [74,346]) to year 1 ($73,236 [114,584]) pre-ESKD. CONCLUSION There were substantial clinical burden and healthcare costs among patients with SLE in the 12 months pre-ESKD diagnosis. The clinical burden and healthcare costs generally increased with each year approaching ESKD diagnosis. Early interventions for patients with SLE could prevent the development of ESKD, mitigating the burden of the disease.

Abstract
OBJECTIVE Assess healthcare costs associated with systemic lupus erythematosus (SLE) flares among patients with and without lupus nephritis (LN). METHODS This retrospective cohort study used medical and pharmacy claims data from the United States-based Optum Clinformatics database to identify adults with SLE between 1 January 2016, and 31 December 2018. Index was the date of a patient's earliest SLE diagnosis claim during the identification period. Patients were categorized based on ICD-9/-10 diagnosis codes into one of two cohorts: SLE with LN (LN) and SLE without LN (non-LN). Baseline characteristics were assessed in the 12 months preceding index (baseline period). The presence, severity, and healthcare costs (in 2019 US dollars) of flares were determined in the 12 months following index (follow-up period). RESULTS Overall, 11,663 patients with SLE were included (LN, n = 2916; non-LN, n = 8747). During the baseline period, a greater proportion of patients in the LN cohort versus non-LN cohort had a Charlson Comorbidity Index score ≥4 (72.5% vs 13.7%) and inpatient stays (41.0% vs 17.0%). A total of 12,190 flares were identified during the follow-up period (LN, 3494; non-LN, 8696). A greater proportion of flares experienced by patients with LN versus those without LN were moderate (61.2% vs 53.6%) and severe (10.6% vs 5.4%). The mean (standard deviation [SD]) number of moderate and severe flares per patient was greater among the LN cohort than the non-LN cohort (moderate: LN, 1.8 [1.2] and non-LN, 1.4 [1.2]; severe: LN, 0.2 [0.6] and non-LN, 0.1 [0.3]). The mean (SD) total healthcare costs associated with SLE flares of any severity were greater for patients with LN (LN, $5842 [9604]; non-LN, $2600 [4249]). The mean (SD) cost per flare increased with severity (mild: LN, $2753 [4640] and non-LN, $1606 [2710]; moderate: LN, $4561 [7156] and non-LN, $2587 [3720]; severe: LN, $29,148 [27,273] and non-LN, $14,829 [19,533]). CONCLUSIONS Patients with SLE with LN have greater healthcare costs than those without LN. Flares among patients with LN were more frequent, severe, and costly than among patients without LN. This highlights the need for treatments that prevent or reduce flares among patients with SLE, both with and without LN.

Cost-Effectiveness of Acthar Gel Versus Standard of Care for the Treatment of Exacerbations in Moderate-to-Severe Systemic Lupus Erythematosus. Adv Ther 2023; 40:194-210. [PMID: 36266383 PMCID: PMC9859852 DOI: 10.1007/s12325-022-02332-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Accepted: 09/21/2022] [Indexed: 01/28/2023]
Abstract
INTRODUCTION Despite current standard of care (SoC), there is an unmet need for the treatment of active systemic lupus erythematosus (SLE). The study assessed the cost-effectiveness of Acthar® Gel (repository corticotropin injection) versus SoC treatment in patients with active, moderate-to-severe SLE from the US payer and societal perspectives over 2 and 3 years. METHODS Cost-effectiveness model was developed using a probabilistic cohort-level state-transition approach. Patients received Acthar Gel in an exacerbation state, and the outcomes were assessed at the end of a 3-month cycle for response achievement based on the probability of treatment success with Acthar Gel. Patients may sustain the response or experience an exacerbation. For the base case scenario, moderate-to-severe SLE was defined as British Isles Lupus Assessment Group (BILAG)-2004 ≥ 20 or SLE Disease Activity Index 2000 (SLEDAI-2K) ≥ 10 and clinical response was based on SLE responder index (SRI)-4. Clinical response, productivity loss, and utility were derived from a phase 4 SLE trial; cost and disutility estimates were sourced from the literature. RESULTS From a payer perspective, Acthar Gel versus SoC resulted in an incremental cost-effectiveness ratio (ICER) of $133,110 per quality-adjusted life-year (QALY) and $94,818 per QALY over 2 and 3 years, respectively. From a societal perspective, Acthar Gel versus SoC results in an ICER of $70,827 per QALY and $32,525 per QALY over 2 and 3 years, respectively. Results from the sensitivity and scenario analyses are consistent with those of the base case model. CONCLUSIONS Acthar Gel is a cost-effective, value-based treatment option for appropriate patients with moderate-to-severe SLE at a willingness-to-pay threshold of $150,000 over 2-3 years from the US payer and societal perspectives. Acthar Gel results in the reduction of direct medical and indirect costs.

Arthritis Care Res (Hoboken) 2023; 75:22-33. [PMID: 36071609 PMCID: PMC9947700 DOI: 10.1002/acr.25015] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 08/16/2022] [Accepted: 09/01/2022] [Indexed: 01/14/2023]
Abstract
OBJECTIVE Climate and social vulnerability contribute to morbidity and health care utilization. We examined associations between the neighborhood Social Vulnerability Index (SVI) and the Heat Vulnerability Index (HVI) and recurrent hospitalizations among individuals with rheumatic conditions. METHODS Using a Massachusetts multihospital centralized clinical data repository, we identified individuals ≥18 years of age with a rheumatic condition who received rheumatology care within 3 years of April 2021. We defined the index date as 2 years before the last encounter and the baseline period as 1 year pre-index date. Addresses were geocoded and linked by census tract to the SVI and the HVI. We used multilevel, multinomial logistic regression to examine the odds of 1-3 and ≥4 hospitalizations (reference = 0) over 2 years post index date by vulnerability index, adjusting for age, gender, race/ethnicity, insurance, and comorbidities. RESULTS Among 14,401 individuals with rheumatic conditions, the mean ± age was 61.9 ± 15.7 years, 70% were female, 79% White, 7% Black, and 2% Hispanic. There were 8,251 hospitalizations; 11,649 individuals (81%) had 0 hospitalizations, 2,063 (14%) had 1-3, and 689 (5%) had ≥4. Adjusting for individual-level factors, individuals living in the highest versus lowest SVI areas had 1.84 times higher odds (95% confidence interval [95% CI] 1.43-2.36) of ≥4 hospitalizations. Individuals living in the highest versus lowest HVI areas had 1.64 times greater odds (95% CI 1.17-2.31) of ≥4 hospitalizations. CONCLUSION Individuals with rheumatic conditions living in areas with high versus low social and heat vulnerability had significantly greater odds of recurrent hospitalizations. Studies are needed to determine modifiable factors to mitigate risks.

Abstract
OBJECTIVE To develop a claims-based algorithm identifying systemic lupus erythematosus (SLE) flares using a linked claims-electronic medical record (EMR) dataset. METHODS This study was a retrospective analysis of linked administrative claims and EMR data spanning 1 January 2003 to 31 March 2019. Included were adult SLE patients with at least 12 months of continuous enrollment in claims data, 12 months of clinical activity in EMR, and an absence of malignancies excluding basal and squamous cell carcinoma. Patient follow-up was divided into 30-day windows, and a proxy SLEDAI-2K score based on the EMR data was calculated for each 30-day period. A flare was defined as an increase of at least 4 from the baseline score. A series of potential flare predictor variables identified in claims were based on a combination of established variables from a previous algorithm, with the addition of other SLE-related indicators based on clinical input. Logistic regression models were built to predict monthly SLE flares. RESULTS Inclusion criteria identified 2427 patients. Results from a logistic model with forward selection capping the number of variables at 10 performed well with a c-statistic of 0.76 and a Brier score of 0.07. The top five predictors were any inpatient admission (OR = 4.76), outpatient office visit (OR = 3.04), MRI (OR = 2.26), ER visit (OR = 2.25), and number of rheumatology visits (OR = 1.75); p < .01 for all. CONCLUSIONS The final algorithm shows promise in providing an alternative and more streamlined way for identifying likely flares in administrative claims data that will advance the study of SLE within the context of flares.

Abstract
The study aims to assess office-based visit trends for lupus patients and evaluate their medication burden, chronic conditions, and comorbidities. This cross-sectional study used data from the National Ambulatory Medical Care Survey (NAMCS), a survey sample weighted to represent national estimates of outpatient visits. Adult patients diagnosed with lupus were included. Medications and comorbidities that were frequently recorded were identified and categorized. Descriptive statistics and bivariate analyses were used to characterize visits by sex, age, race/ethnicity, insurance type, region, and reason for visit. Comorbidities were identified using diagnosis codes documented at each encounter. There were 27,029,228 visits for lupus patients from 2006 to 2016, and 87% them were on or were prescribed medications. Most visits were for female (88%), white (79%), non-Hispanic (88%) patients with private insurance (53%). The majority of patients were seen for a chronic routine problem (75%), and 29% had lupus as the primary diagnosis. Frequent medications prescribed were hydroxychloroquine (30%), prednisone (23%), multivitamins (14%), and furosemide (9%). Common comorbidities observed included arthritis (88%), hypertension (25%), and depression (13%). Prescription patterns are reflective of comorbidities associated with lupus. By assessing medications most frequently prescribed and comorbid conditions among lupus patients, we showcase the complexity of disease management and the need for strategies to improve care.

Abstract
Objectives The incidence and prevalence of AAV in Asia remain poorly understood, especially in a nationwide setting. This study investigated the incidence, prevalence, and healthcare burden of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) in South Korea by analyzing a national database. Methods This study included patients with AAV identified from the National Health Insurance Service Database of South Korea from 2002 to 2018. Patients were diagnosed with AAV in a general or tertiary hospital and were registered in the individual payment beneficiaries program or were prescribed glucocorticoids. A calendar-based meteorological definitions were adopted to assess the differences in the incidence of AAV according to season. The average healthcare expenditure and patient outcomes of mortality and end-stage renal disease (ESRD) in patients with AAV were compared to 1:10 age, sex and residential area matched controls. Results A total of 2,113 patients [708, 638, and 767 with microscopic polyangiitis (MPA), granulomatosis with polyangiitis, and eosinophilic granulomatosis with polyangiitis, respectively] were identified. The annual incidence and prevalence of AAV increased continuously, and MPA being the most common disease subtype after 2015. The highest incidence and prevalence of AAV was 0.48/100,000 person-years (PY) and 2.40/100,000 PY in 2017 and 2018, respectively. There were no significant differences in monthly and seasonal incidence of AAV. The average expense of medical care, overall mortality, and ESRD rates of patients with AAV were higher in patients with AAV than in controls, especially in the case of MPA. Conclusion An increasing trend of AAV diagnosis observed is consistent with the evidence that AAV is more common in recent years; however, a relatively lower incidence and prevalence was observed compared to that in Western countries. The higher medical cost and rates of mortality and ESRD in AAV emphasize the early recognition and implementation of optimal treatment for these patients.

Clin Gastroenterol Hepatol 2022; 20:1480-1487.e7. [PMID: 34217877 DOI: 10.1016/j.cgh.2021.06.047] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 06/25/2021] [Accepted: 06/29/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Digestive diseases represent a diverse group of clinical conditions that impact the population. Their heterogeneity in classification, presentation, acuity, chronicity, and need for drug therapy presents a challenge when comparing and contrasting the burden associated with these conditions. Prior studies use an outdated classification system and aggregate costs at the population level or focus on specific diseases, limiting the ability to characterize the overall landscape. Our aim was to provide the most up-to-date assessment of cost, utilization, and prevalence associated with digestive diseases. METHODS We examined digestive disease claims and payment data for a commercially insured adult population between 2016 and 2018 to provide a comprehensive summary of costs, utilization, and prevalence across 38 conditions. Outcome variables included point prevalence and relative prevalence, annualized all-cause medical and drug costs, digestive disease-specific average medical cost, digestive disease-specific cost per fill, and utilization by clinical setting and by clinical condition. RESULTS A total of 7,297,435 individuals with a digestive disease diagnosis were included in the study. The point prevalence of having a digestive disease in the total population was 24%. Annualized total costs by clinical category ranged from $10,038 (eosinophilic esophagitis) to $107,007 (hepatitis C), with medical costs accounting for most of the expenditures in a majority of conditions. Annualized total costs for common conditions included $39,653 for alcoholic liver disease, $42,554 for acute pancreatitis, $62,735 for Crohn's disease, $13,948 for functional gastrointestinal disorders, $53,214 for nonalcoholic cirrhosis, and $36,441 for ulcerative colitis. Average cost of inpatient stays ranged from $12,218 (noninfectious gastroenteritis/colitis) to $78,259 (nonalcoholic steatohepatitis). Outpatient visits ranged from $784 (gastrointestinal infection) to $4629 (gallbladder and biliary tract disease). Average drug cost per fill ranged from $83 (gastroesophageal reflux disease) to $1458 (hepatitis C). A total of 27,429,046 clinical encounters occurred across all conditions during the study period, with 90% taking place as outpatient visits. Abdominal pain was the single largest contributor to outpatient visits and emergency department to home encounters. Inpatient stays were considerably more heterogeneous, with no condition accounting for more than 12% (gallbladder and biliary tract disease) of the total. CONCLUSIONS The results demonstrate digestive diseases are common, heterogeneous in cost and utilization, and collectively exact a significant financial burden on the U.S. adult population.

Abstract
OBJECTIVE SLE is a chronic, multiorgan, autoimmune disease; however, current prevalence estimates are dated and often from non-generalisable patient populations, and quality of life and patient-reported outcomes in the real-world SLE population are not well-published. The present study used the Medical Expenditure Panel Survey (MEPS), a generalisable US data source encompassing a representative sample of regions/payers, to estimate SLE prevalence and characterise disease burden compared with non-SLE respondents. METHODS Retrospective population-based survey data weighted to the full US population from MEPS for the calendar years 2016-2018, pooled over the full study period, was used. The primary inclusion criteria included adults with self-reported SLE and either a record of SLE-related medication and/or rheumatologist visit in the calendar year. A matched-control cohort was created and the general non-SLE MEPS population was matched to MEPS SLE respondents by gender, age, region and MEPS reporting year using a 1:5 ratio. RESULTS From 2016 to 2018, 96 996 adults reported annual data in MEPS, of whom 154 respondents met the primary SLE definition, equivalent to 490 385 weighted number of adults with SLE. The prevalence of SLE was 195 (95% CI 149 to 242) per 100000, with greater prevalence observed in the US South, African-American/black and publicly insured people and females. SLE respondents reported limitations in physical function at 3 times greater rate (45% vs 15%; p<0.0001), higher rates of pain-limiting work (67% vs 39%; p<0.001) and feeling depressed 'nearly every day' (7% vs 2%; p<0.001) compared with non-SLE respondents. All-cause healthcare and prescription expenses were significantly higher in SLE respondents (US$17 270 vs US$8350 (p<0.0001) and US$4512 vs US$1952 (p<0.001), respectively, in 2018 US dollars). CONCLUSION Wide variation of SLE prevalence exists among patients of different regional, demographic and payer groups; SLE is associated with adverse quality of life, productivity and economic outcomes compared with non-SLE respondents.

Abstract
OBJECTIVES To evaluate health care utilization and costs for patients with systemic lupus erythematosus (SLE) by disease severity. METHODS We searched PubMed and Embase from January 2000 to June 2020 for observational studies examining health care utilization and costs associated with SLE among adults in the United States. Two independent reviewers reviewed the selected full-text articles to determine the final set of included studies. Costs were converted to 2020 US $. RESULTS We screened 9224 articles, of which 51 were included. Mean emergency department visits were 0.3-3.5 per year, and mean hospitalizations were 0.1-2.4 per year (mean length of stay 0.4-13.0 days). Patients averaged 10-26 physician visits/year. Mean annual direct total costs were $17,258-$63,022 per patient and were greater for patients with moderate or severe disease ($19,099-$82,391) compared with mild disease ($12,242-$29,233). Mean annual direct costs were larger from commercial claims ($24,585-$63,022) than public payers (Medicare and Medicaid: $18,302-$27,142). CONCLUSIONS SLE remains a significant driver of health care utilization and costs. Patients with moderate to severe SLE use more health care services and incur greater direct and indirect costs than those with mild disease.

Abstract
Approximately 100 million adults in the United States have chronic pain, though only a subset utilizes the vast majority of healthcare resources. Multidisciplinary care has been shown to improve outcomes in a variety of clinical conditions. There is concern that multidisciplinary care of chronic pain patients may overwhelm existing resources and increase healthcare utilization due to the volume of patients and the complexity of care. We report our findings on the use of multidisciplinary conferences (MDC) to facilitate care for the most complex patients seen at our tertiary center. Thirty-two of nearly 2,000 patients seen per year were discussed at the MDC, making up the top 2% of complex patients in our practice. We evaluated patients' numeric rating score (NRS) of pain, medication use, hospitalizations, emergency department visits, and visits to pain specialists prior to their enrollment in MDC and 1 year later. Matched samples were compared using Wilcoxon's signed rank test. Patients' NRS scores significantly decreased from 7.64 to 5.54 after inclusion in MDC (p < 0.001). A significant decrease in clinic visits (p < 0.001) and healthcare utilization (p < 0.05) was also observed. Opioid and non-opioid prescriptions did not change significantly (p = 0.43). 83% of providers agreed that MDC improved patient care. While previous studies have shown the effect of multi-disciplinary care, we show notable improvements with a team established around a once-a-month MDC.

Abstract
OBJECTIVE To assess the economic burden of patients with SLE by disease severity in the USA 1 year before and after diagnosis. METHODS Patients aged ≥18 years with a first SLE diagnosis (index date) between January 2005 and December 2014 were identified from administrative commercial claims data linked to electronic medical records (EMRs). Disease severity during the year after diagnosis was classified as mild, moderate, or severe using claims-based algorithms and EMR data. Healthcare resource utilisation (HCRU) and all-cause healthcare costs (2017 US$) were reported for 1 year pre-diagnosis and post-diagnosis. Generalised linear modelling examined all-cause costs over 1 year post-index, adjusting for baseline demographics, clinical characteristics, Charlson Comorbidity Index and 1 year pre-diagnosis costs. RESULTS Among 2227 patients, 26.3% had mild, 51.0% moderate and 22.7% severe SLE. Mean per-patient costs were higher for patients with moderate and severe SLE compared with mild SLE during the year before diagnosis: mild US$12 373, moderate $22 559 and severe US$39 261 (p<0.0001); and 1-year post-diagnosis period: mild US$13 415, moderate US$29 512 and severe US$68 260 (p<0.0001). Leading mean cost drivers were outpatient visits (US$13 566) and hospitalisations (US$10 252). Post-diagnosis inpatient utilisation (≥1 stay) was higher for patients with severe (51.2%) and moderate (22.4%) SLE, compared with mild SLE (12.8%), with longer mean hospital stays: mild 0.47 days, moderate 1.31 days and severe 5.52 days (p<0.0001). CONCLUSION HCRU and costs increase with disease severity in the year before and after diagnosis; leading cost drivers post-diagnosis were outpatient visits and hospitalisations. Earlier diagnosis and treatment may improve health outcomes and reduce HCRU and costs.

Abstract
Systemic lupus erythematosus (SLE) is characterized by immune system dysfunction and is clinically heterogeneous, exhibiting renal, dermatological, neuropsychiatric, and cardiovascular symptoms. Clinical and physiological assessment is usually inadequate for diagnosing and assessing pathophysiological processes in SLE. Clinical and immunological biomarkers could play a critical role in improving diagnosis, assessment, and ultimately, control of SLE. This article reviews clinical and immunological biomarkers that could diagnose and monitor disease activity in SLE, with and without organ-specific injury. In addition, novel SLE biomarkers that have been discovered through “omics” research are also reviewed.

Abstract
Introduction We evaluated incidence, prevalence, costs, and healthcare utilization associated with systemic lupus erythematosus (SLE) in patients in Germany. Methods Adult patients with SLE were identified from the German Betriebskrankenkassen (BKK) health insurance fund database between 2009 and 2014. SLE incidence and prevalence were calculated for each year and extrapolated (age and sex adjusted) to the German population. The 2009 SLE population was followed through 2014. Healthcare utilization and costs for patients with SLE were calculated and compared with controls matched by age, sex, and baseline Charlson Comorbidity Index scores. Results This analysis included 1160 patients with SLE. Estimated SLE incidence between 2009 and 2014 ranged from 4.59 to 6.89 per 100,000 persons and prevalence ranged from 37.32 to 47.36 per 100,000. SLE incidence in Germany in 2014 was 8.82 per 100,000 persons; prevalence was 55.80 (corrected for right-censored data). At baseline, 12.8, 41.7, and 45.5% of patients were categorized as having mild, moderate, and severe SLE, respectively. Patients with SLE had greater mean (standard deviation [SD]) annual medical costs compared with matched controls 1 year after index diagnosis (€6895 [14,424] vs. €3692 [3994]; P < 0.0001) and in subsequent years. Patients with moderate or severe SLE had significantly more hospitalizations, outpatient visits, and prescription medication use compared with matched controls. Mean annual costs for 5 years ranged from €1890 to 3010, €4867 to 5876, and €8396 to 10,001 for patients with mild, moderate, and severe SLE, respectively. Conclusions SLE incidence in Germany increased 1.4-fold over 5 years. Patients with SLE have higher healthcare costs, and costs increase with baseline severity. Early and effective treatments may delay progression and reduce the burden of SLE.
