RESUMEN
INTRODUCTION: No validated algorithm exists to identify patients with neuromyelitis optica spectrum disorder (NMOSD) in healthcare claims data. We developed and tested the performance of a healthcare claims-based algorithm to identify patients with NMOSD. METHODS: Using medical record data of 101 adults with NMOSD, multiple sclerosis (MS), or myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), we tested the sensitivity and specificity of claims-based algorithms developed through interviews with neurologists. We tested the best-performing algorithm's face validity using 2016-2019 data from IBM MarketScan Commercial and Medicare Supplemental databases. Demographics and clinical characteristics were reported. RESULTS: Algorithm inclusion criteria were age ≥ 18 years and (≥1 NMO diagnosis [or ≥ 1 transverse myelitis (TM) and ≥ 1 optic neuritis (ON) diagnosis] and ≥ 1 NMOSD drug) or (≥2 NMO diagnoses ≥90 days apart). Exclusion criteria were MS diagnosis or use of MS-specific drug after last NMO diagnosis or NMOSD drug; sarcoidosis diagnosis after last NMO diagnosis; or use of ≥1 immune checkpoint inhibitor. In medical record billing data of 50 patients with NMOSD, 30 with MS, and 21 with MOGAD, the algorithm had 82.0% sensitivity and 70.6% specificity. When applied to healthcare claims data, demographic and clinical features of the identified cohort were similar to known demographics of NMOSD. CONCLUSIONS: This clinically derived algorithm performed well in medical records. When tested in healthcare claims, demographics and clinical characteristics were consistent with previous clinical findings. This algorithm will enable a more accurate estimation of NMOSD disease burden using insurance claims datasets.
RESUMEN
INTRODUCTION: Antiviral therapy may be underutilized in patients at high risk for increased clinical and economic burden (e.g. older adults). We aimed to examine the benefits associated with antiviral treatment of seasonal influenza among treated and untreated Medicare beneficiaries. METHODS: This retrospective study of Medicare Claims Research Identifiable Files identified patients ≥66 years old with an influenza diagnosis in outpatient setting between October 2016-March 2019 (flu seasons 2016-2018). Index date defined as date of first claim with influenza diagnosis; baseline as the 12 months pre-index. Treated patients received antivirals ≤2 days from index. Untreated patients had no antivirals ≤6 months post-index. Treated/untreated patients were 1:1 propensity score matched. Outcomes (death, all-cause and respiratory-related healthcare resource utilization [HCRU] and costs) were assessed until death or up to 6 months post-index. Descriptive statistics were reported; Kaplan-Meier estimation was used for survival over time. RESULTS: Among 116,901 matched patient pairs, all-cause mortality within 6 months from index diagnosis was 1.6% among treated versus 4.3% among untreated patients. Rates (treated versus untreated) of all-cause inpatient hospitalizations during follow-up were 13.9% versus 22.7% and respiratory-related hospitalizations were 4.2% versus 9.0%. Mean (SD) total all-cause and respiratory-related costs were $9,830 ($18,616.0) and $900 ($4016.4) among the treated, respectively, versus $13,207 ($24,405.1) and $2,024 ($7,623.7) among untreated, respectively. All differences were statistically significant (p < 0.001). CONCLUSIONS: Lack of antiviral treatment is associated with increased mortality, HCRU, and economic burden in older Medicare beneficiaries with seasonal influenza. Future research should investigate whether the choice of antivirals affects influenza burden.
Previous studies have shown that antiviral drugs help prevent flu-related complications and lower healthcare utilization and costs. However, these previous studies have focused on working aged people with existing health problems. Our study looks at how antiviral treatment can lower the health and financial burden caused by the flu in older adults. Using a Medicare claims database from the 20162018 flu season, we identified 116,901 matched (treated versus untreated) patient pairs. All-cause mortality within 6 months from the index diagnosis (defined as the first claim with a flu diagnosis) was 1.6% among treated versus 4.3% among untreated patients. Rates (treated versus untreated) of all-cause inpatient hospitalizations during follow-up (defined as 6 months after the index diagnosis date) were 13.9% versus 22.7% and respiratory-related hospitalizations were 4.2% versus 9.0%. Mean total all-cause and respiratory-related costs were $9,830 and $900 among the treated, respectively, versus $13,207 and $2,024 among untreated, respectively. All differences were statistically significant (p < 0.001). This analysis of older adults with the flu found that prompt antiviral treatment is associated with lower rates of mortality and acute complications, reduced hospitalization, and lower healthcare costs. Use of antiviral treatment for patients at high risk of flu, such as older adults, is warranted.

AIMS: To provide more recent estimates of healthcare utilization and costs in Huntington's disease (HD) in the Medicaid population. MATERIALS AND METHODS: This retrospective analysis used administrative claims data for HD beneficiaries (≥1 HD claim; ICD-9-CM 333.4) from Medicaid Analytic eXtract data files from 1 January 2010-31 December 2014. The date of the first HD claim during the identification period (1 January 2011-31 December 2013) was assigned as the index date. If a beneficiary had multiple HD claims during the identification period, one was randomly chosen as the index date. Beneficiaries were required to be continuously enrolled in fee-for-service plans during the 1-year pre-index and post-index periods. Medicaid beneficiaries without HD were drawn from a 100% random sample and matched (3:1) to those with HD. Beneficiaries were classified by disease stage (early/middle/late). All-cause and HD-related (any utilization related to HD diagnosis or symptoms associated with HD) healthcare utilization and costs were reported. RESULTS: A total of 1,785 beneficiaries without HD were matched to 595 beneficiaries with HD (139 early-, 78 middle-, and 378 late-stage). The mean (SD) annual total costs were higher for beneficiaries with HD than beneficiaries without HD ($73,087 [$75,140] vs. $26,834 [$47,659], p <.001) and driven by inpatient costs ($45,190 [$48,185] vs. $13,808 [$39,596], p <.001). Total healthcare costs were highest among beneficiaries with late-stage HD (mean [SD] cost: $22,797 [$31,683] for early-stage HD vs. $55,294 [$129,290] for middle-stage HD vs. $95,251 [$60,197] for late-stage HD; p <.001). LIMITATIONS: Administrative claims are intended for billing purposes and subject to coding errors. This study did not address functional status, which may provide further insight to late-stage and end-of-life burden of HD, and indirect costs. CONCLUSIONS: Medicaid beneficiaries with HD have higher acute healthcare utilization and costs compared to beneficiaries without HD, which tend to increase with disease progression, indicating that HD beneficiaries at later disease stages have greater burden.
Huntington's disease (HD) is a degenerative genetic disorder marked by progressive decline in cognitive and motor functions, leading to severe disability and loss of independence. The median and mean survival time after a diagnosis of HD is 15 years. Little is known about the kinds of health services used or costs associated with HD in the United States (US) in the Medicaid population. The study objective was to estimate healthcare utilization and direct medical spending among Medicaid beneficiaries with HD. The mean annual total costs were higher for beneficiaries with HD than beneficiaries without HD ($73,087 vs. $26,834). Mean total healthcare costs were highest among beneficiaries with late-stage HD ($22,797 for early-stage HD vs. $55,294 for middle-stage HD vs. $95,251 for late-stage HD). Medicaid beneficiaries with HD have higher acute healthcare utilization and costs compared to beneficiaries without HD, with utilization and costs increasing with disease progression, indicating that HD beneficiaries at later disease stages have greater burden.

Introduction: Initial clinical manifestations of transthyretin amyloidosis (ATTR) are not well understood, making timely diagnosis challenging. Methods: Patients aged ≥68 years newly diagnosed with ATTR were identified using Medicare Research Identifiable Files. Symptom manifestation and healthcare utilization were measured during 3 years pre-diagnosis; demographics and comorbidity index during 1-year pre-diagnosis. Controls (ATTR-free) were matched 1:1 to patients with ATTR based on age, sex and region; same index date and enrollment as match. Results: We identified 552 matched ATTR-control pairs: mean age 78.3 (standard deviation 6.3) and 64.5% male. Among patients with ATTR (vs controls), cardiovascular conditions (92.9 vs 75.9%) and hospitalization (54.0 vs 35.5%) were frequent during 3 years pre-diagnosis. Conclusion: Patients with ATTR have multiple symptoms and hospitalizations pre-diagnosis, recognition of which may facilitate earlier diagnosis and treatment.

INTRODUCTION: Huntington's disease (HD) is a rare, genetic, and ultimately fatal neurodegenerative disease, with a devastating impact on individuals and families across generations. Few estimates of HD epidemiology in the United States (US) exist. METHODS: This study employed a retrospective cross-sectional design to examine the epidemiology of HD in the US Medicare and Medicaid beneficiary populations using 2016-2017 claims data from the Medicare 100% Research Identifiable Files (RIFs) and 2014 claims data from the Medicaid Analytic eXtract (MAX) files for 17 states. Medicare beneficiaries ≥65 years with a diagnosis of HD (≥1 claim with ICD-10-CM code G10) in 2017 and Medicaid beneficiaries <65 years with a diagnosis of HD (≥1 claim with ICD-9-CM code 333.4) in 2014 were identified. The study outcomes included the 2017 prevalence proportion and incidence rate of HD in the Medicare population and the 2014 prevalence proportion of HD in the Medicaid population. RESULTS: In the Medicare population, 1,941 prevalent and 819 incident cases of HD were identified in 2017, corresponding to a prevalence proportion of 13.1 per 100,000 persons and incidence rate of 6.1 per 100,000 person-years. In the Medicaid population, 353 prevalent cases of HD were identified in 2014, corresponding to a prevalence proportion of 15.2 per 100,000 persons. CONCLUSION: This study suggests that prevalence and incidence of HD in the US may be higher than previously estimated. This has important implications in raising awareness of HD among providers and payers and ensuring availability of and access to services for HD patients and care partners in the Medicare and Medicaid populations.

OBJECTIVE: Estimate the annual cost of care in the 5 years following a cancer diagnosis for 17 invasive cancer types, by stage at diagnosis. METHODS: We used 2012-2016 data from the Surveillance, Epidemiology, and End Results (SEER) registry-Medicare claims database to examine cost of care among Medicare beneficiaries with a confirmed cancer diagnosis based on International Classification of Diseases for Oncology, Third Edition histology codes reported in SEER. Beneficiaries contributed to the annual cost calculations (Years 1-5) using their observed time after diagnosis. Beneficiaries were continuously enrolled in fee-for-service Medicare Parts A/B and Part D during follow-up. Total, inpatient, outpatient, and pharmacy cancer-related service costs were calculated. RESULTS: From 2012 to 2016, we identified 597,778 Medicare beneficiaries with incident cancer diagnosis within 5 years (Stage I, II, III, and IV: 32.6%, 33.4%, 15.9%, and 18.0%, respectively). In Year 1, mean (standard deviation) total costs for Stage I diagnoses varied from $7640 ($17,378) (prostate) to $94,636 ($117,636) (pancreas). Total costs increased by stage and reached $58,783 ($92,344) (prostate) to $156,982 ($175,009) (stomach) for Stage IV diagnoses in Year 1. Costs in Year 1 were significantly higher for Stage IV diagnoses than for earlier stages across all cancer types. In Years 2-5, total costs were lower than in Year 1 but continued to increase by stage. CONCLUSIONS: Beneficiaries diagnosed at later stages of cancer have higher costs of care (up to 7 times as much) than those diagnosed at earlier stages. Earlier cancer diagnosis may lead to more efficient treatment and decreased management cost.

BACKGROUND: Additional real-world studies are needed to more fully elucidate the effectiveness of antifibrotic treatment in slowing the progression of idiopathic pulmonary fibrosis (IPF). OBJECTIVE: To compare mortality and hospitalization between Medicare beneficiaries with IPF who initiate antifibrotic therapy and those who did not receive treatment. METHODS: A retrospective observational study of Medicare beneficiaries using the 100% Medicare Research Identifiable File was conducted. We included patients aged 67 years and over diagnosed with IPF (≥ 1 inpatient or ≥ 2 outpatient claims with IPF diagnosis) during the study period (January 1, 2010-December 31, 2017). Patients who initiated antifibrotic treatment (pirfenidone or nintedanib) between October 15, 2014 (FDA approval date) and December 31, 2017 (ie, treated patients) were compared with those who did not receive treatment during a historical period (January 1, 2012-October 14, 2014) before the availability of antifibrotics (ie, untreated historical controls). Patients were matched by propensity score, and the outcomes, mortality, and hospitalization (all cause and respiratory related) were compared using a Cox proportional hazards model. RESULTS: We identified 4,641 treated patients and 4,641 propensity score-matched controls who met all study criteria; 352 treated patients who lacked matches were excluded from the study. Cox regression analysis of treated patients vs matched controls showed a significantly lower risk of mortality (HR = 0.62, 95% CI = 0.57-0.68); lower risk of hospitalization (HR = 0.71, 95% CI = 0.67-0.76; HR = 0.70, 95% CI = 0.64-0.76); and lower rate in number of hospitalizations per month (incident rate ratio [IRR] = 0.65, 95% CI = 0.60-0.71; IRR = 0.65, 95% CI = 0.58-0.73). CONCLUSIONS: This study suggests that treatment with antifibrotics may confer a survival benefit and protection against all-cause and respiratory-related hospitalization for IPF patients.

AIMS: To examine healthcare utilization and costs in a US Medicare population diagnosed with Huntington's disease (HD). METHODS: This was a retrospective matched cohort study using Medicare fee-for-service (FFS) claims data using 2013-2017 Research Identifiable Files. Medicare beneficiaries diagnosed with HD based on the presence of at least one medical claim with an International Classification of Diseases, Ninth or Tenth Revision, Clinical Modification (ICD-9/10-CM) diagnosis code for HD (ICD-9-CM: 333.4; ICD-10-CM: G10) during the identification period (2014-2016). Beneficiaries without HD were drawn from a 5% random sample of Medicare beneficiaries and 1:1 matched to those with HD for comparison. All-cause and HD-related (any utilization related to HD diagnosis or symptoms associated with HD) healthcare utilization and costs were reported. RESULTS: We identified 3,688 matched pairs of beneficiaries with and without HD. Of those with HD, 1,922 (52.1%) were late-stage, 916 (24.8%) were middle-stage, and 850 (23.1%) were early-stage. Mean [SD] annual total healthcare costs were higher for HD beneficiaries than beneficiaries without HD ($41,631 [57,393] vs. $17,222 [31,218], p < .001) and were primarily driven by outpatient pharmacy costs ($19,182 [45,469] vs. $4,318 [11,553], p < .001). In the stratified analysis, total healthcare costs were highest among beneficiaries with late-stage HD (mean [SD] cost: $20,475 [$41,122] for early-stage vs. $29,733 [$44,977] for middle-stage vs. $56,657 [$64,185] for late-stage; p < .001). LIMITATIONS: Results are not generalizable to beneficiaries enrolled in other non-FFS Medicare plans. Administrative claims are intended for billing purposes, not research, and may not capture all symptoms, comorbidities, and other adverse events. CONCLUSIONS: This original, comprehensive analysis of healthcare utilization and economic burden among Medicare beneficiaries with HD found that healthcare needs and associated costs are substantially higher among Medicare beneficiaries who are diagnosed with HD compared to beneficiaries without HD.

BACKGROUND: Despite emerging treatments for hereditary transthyretin (ATTRv) amyloidosis, the disease is often misdiagnosed, with reported diagnostic delays of up to several years. Knowledge of the patient journey leading up to diagnosis may help to promote earlier intervention. The study's objective was to examine patient clinical characteristics and healthcare utilization prior to ATTRv amyloidosis diagnosis. METHODS: Patients ≥ 18 years and newly diagnosed with ATTRv amyloidosis identified in IBM® MarketScan® Commercial and Medicare Supplemental data using a claims-based algorithm as follows: diagnosis required ≥ 1 medical claim with relevant amyloidosis diagnosis code (ICD-10-CM: E85.0-.4, E85.89, E85.9; excludes light chain and wild type) during identification (ID) period (1/1/2016-12/31/2017), and ≥ 1 occurrence of qualifying criteria during 2011-2017: ≥ 15 days diflunisal use without > 30-day gap, liver transplant, or claim with specific codes E85.1 or E85.2. The index date was defined as the date of first claim with amyloidosis diagnosis code in ID period. Patients had continuous enrollment ≥ 5 years pre-index date (look-back period). Occurrence of selected comorbid conditions and symptoms and healthcare utilization (testing, emergency department visits and hospitalization) measured during the look-back period; demographics, physician specialty, and Charlson comorbidity index (CCI) measured 1 year pre-index. Patients with an ICD-9/10 amyloidosis code during the look-back period were excluded. An ATTRv-free reference cohort was created from a random sample of enrollees who lacked any diagnosis of amyloidosis and matched 3:1 to ATTRv patients on age, gender, and region to provide reference values; same index and enrollment requirement as match. RESULTS: For the 141 qualifying patients with ATTRv and 423 matched controls, mean (standard deviation) age was 62.5 (14.2) years and 53.9% were female. Mean CCI for ATTRv cohort was 2.7 (3.0) versus 1.1 (1.9) among controls. Selected comorbidities, testing, visits, and hospitalization were common among patients with ATTRv during the look-back period with higher rates versus controls. CONCLUSIONS: Patients with ATTRv amyloidosis experience multiple neurological, cardiovascular, and other clinical manifestations, testing, and hospitalization prior to diagnosis. Occurrence of potential markers of illness is most common in the year before diagnosis.

OBJECTIVE: To investigate the clinical and health care burden of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) in the United States. STUDY DESIGN: Retrospective, cross-sectional design with analyses of patient visits from 2 databases. SETTING: National Ambulatory Medical Care Survey (NAMCS, 2012-2016) and State Ambulatory Surgery and Services Databases (SASD, 2012-2015) in available states. METHODS: In each analysis, we identified patients (≥18 years old) with a diagnosis of CRSwNP (ICD-9-CM: 471.x; ICD-10-CM: J33.x) in the visit record during the study period. CRS patients without polyps (CRSsNP: ICD-9-CM: 473.x, ICD-10-CM: J32.x; without CRSwNP codes) were identified for comparison. In the SASD, we focused on visits involving relevant sinus procedures. Outcomes included comorbidities, diagnostic testing, and prescribed medication (NAMCS) and surgery visit characteristics (SASD). RESULTS: We identified 2272 NAMCS records from physician offices (183 CRSwNP, 2089 CRSsNP). Most visits were for patients aged <65 years (78.8%, 80.6%) and privately insured (67.7%, 61.5%); CRSwNP visits had a male majority (56.3%, 35.4%). CRSwNP vs CRSsNP visits more often reported asthma (40.2%, 10.3%), allergic rhinitis (14.0%, 8.7%), and congestion (22.0%, 21.1%), with the use of glucocorticoids (21.0%, 17.7%) and nasal allergy medication (26.2%, 10.2%). In the SASD, 427,306 surgery visits were identified (71,195 CRSwNP, 356,111 CRSsNP); demographics were similar to NAMCS. CRSwNP surgeries involved more sinus types (59.3%, 41.4%). Surgeries were mostly elective (>99%) and completed quickly (<2 hours), without perioperative complications (>99%), followed by routine discharge (>91%); follow-up visits were common (14.9%, 13.9%). CONCLUSION: CRSwNP compared to CRSsNP patients have a distinct clinical experience, with moderately higher medication need and more extensive surgery.
RESUMEN
Aim: Compare healthcare utilization and costs between Medicare beneficiaries with idiopathic pulmonary fibrosis (IPF) receiving pirfenidone or nintedanib. Methods: Retrospective cohort study of Medicare beneficiaries (100% Research Identifiable Files) with IPF who initiated pirfenidone or nintedanib between 15 October 2014 and 31 December 2015. Inverse probability of treatment weighting using propensity scores adjusted for baseline covariates. Outcomes: hospitalization and monthly costs. Results: Hazard and incidence rate ratios (95% CI) for all-cause (0.79 [0.68-0.91]; 0.69 [0.59-0.82]) and respiratory-related (0.80 [0.65-0.97]; 0.71 [0.57-0.90]) hospitalizations favored pirfenidone versus nintedanib. Monthly inpatient costs were lower for pirfenidone versus nintedanib patients; outpatient and pharmacy costs were similar. Conclusion: In patients with IPF, pirfenidone compared with nintedanib has a moderate but significant protective effect on hospitalization, corresponding to lower inpatient costs.

INTRODUCTION: Little is known about the burden of hereditary transthyretin (ATTRv) amyloidosis, a genetic, progressive, and fatal disease caused by extracellular deposition of transthyretin amyloid fibrils. The study's aim was to estimate costs and disease burden associated with ATTRv amyloidosis in a real-world setting. METHODS: Using IBM® MarketScan® Commercial and Medicare Supplemental data, we identified patients at least 18 years of age with newly diagnosed ATTRv amyloidosis. Diagnosis required at least one medical claim with relevant diagnosis code (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM] 277.30-.31, 277.39; ICD-10-CM E85.0-.4, E85.89, E85.9) between January 1, 2014 and December 31, 2016, and at least one additional criterion occurring during study period (2013-2017): at least 15 days diflunisal use without more than a 30-day gap; liver transplant; or claim with codes E85.1 or E85.2. First diagnosis date was study index. Continuous enrollment 1-year pre-index (baseline) and post-index (follow-up) was required. Patients with baseline amyloidosis diagnosis were excluded. Outcomes of interest were comorbidities and 1-year follow-up healthcare utilization and costs (also reported quarterly). RESULTS: Among 185 qualifying patients, mean age was 59.2 years (standard deviation 15.2), 54.1% were female, and baseline Charlson comorbidity index was 2.2 (2.5). Neuropathy (30.3%), diabetes (27.0%), and cardiovascular-related comorbidities, including dyspnea (25.9%) and congestive heart failure (21.6%), were common during follow-up. Nearly a quarter of patients (24.9%) were hospitalized during follow-up. Most hospitalizations and emergency department visits occurred in the first quarter post-diagnosis (18.9%, 17.8%, respectively) and dropped in subsequent quarters. The annual mean total cost was $64,066, with inpatient services contributing the majority of the expenses ($34,461), followed by outpatient ($23,853), and then pharmacy ($5752). As with utilization, costs were highest in the first quarter post-diagnosis and dropped in subsequent quarters. CONCLUSION: Patients newly diagnosed with ATTRv amyloidosis have substantial healthcare utilization and costs in the first year, primarily the initial months, post-diagnosis. Further research should examine later costs associated with disease progression and end-of-life care.
RESUMEN
The burden of complications associated with peripheral intravenous use is underevaluated, in part, due to the broad use, inconsistent coding, and lack of mandatory reporting of these devices. This study aimed to analyze the clinical and economic impact of peripheral intravenous-related complications on hospitalized patients. This analysis of Premier Perspective® Database US hospital discharge records included admissions occurring between July 1, 2013 and June 30, 2015 for pneumonia, chronic obstructive pulmonary disease, myocardial infarction, congestive heart failure, chronic kidney disease, diabetes with complications, and major trauma (hip, spinal, cranial fractures). Admissions were assumed to include a peripheral intravenous. Admissions involving surgery, dialysis, or central venous lines were excluded. Multivariable analyses compared inpatient length of stay, cost, admission to intensive care unit, and discharge status of patients with versus without peripheral intravenous-related complications (bloodstream infection, cellulitis, thrombophlebitis, other infection, or extravasation). Models were conducted separately for congestive heart failure, chronic obstructive pulmonary disease, diabetes with complications, and overall (all 7 diagnoses) and adjusted for demographics, comorbidities, and hospital characteristics. We identified 588 375 qualifying admissions: mean (SD), age 66.1 (20.6) years; 52.4% female; and 95.2% urgent/emergent admissions. Overall, 1.76% of patients (n = 10 354) had peripheral intravenous-related complications. In adjusted analyses between patients with versus without peripheral intravenous complications, the mean (95% confidence interval) inpatient length of stay was 5.9 (5.8-6.0) days versus 3.9 (3.9-3.9) days; mean hospitalization cost was $10 895 ($10 738-$11 052) versus $7009 ($6988-$7031). Patients with complications were less likely to be discharged home versus those without (62.4% [58.6%-66.1%] vs 77.6% [74.6%-80.5%]) and were more likely to have died (3.6% [2.9%-4.2%] vs 0.7% [0.6%-0.9%]). Models restricted to single admitting diagnosis were consistent with overall results. Patients with peripheral intravenous-related complications have longer length of stay, higher costs, and greater risk of death than patients without such complications; this is true across diagnosis groups of interest. Future research should focus on reducing these complications to improve clinical and economic outcomes.

INTRODUCTION: Conventional pharmaceutical interventions for inflammatory bowel disease (IBD) provide limited disease/symptom control and are associated with an increased risk of adverse events (AEs). These limitations increase patient morbidity, medical resource utilization (MRU), and costs. METHODS: The IQVIA™ Real-World Data Adjudicated Claims-US database was leveraged to identify adult patients (> 18 years) with Crohn's disease (Crohn's) or ulcerative colitis (UC), who were new and chronic users (≥ 60 days) of oral corticosteroids (OCS), immunosuppressants (IS), anti-tumor necrosis factor agents (anti-TNF) or combinations thereof. Using aminosalicylate-treated patients as a reference, we compared AE incidence, MRU, and medical costs across drug classes. RESULTS: The analysis included 30,676 patients (Crohn's: n = 14,528; UC: n = 16,148). OCS monotherapy was the strongest predictor of any AE occurring [Crohn's: hazard ratio 1.62 (1.51-1.73); UC: hazard ratio 1.57 (1.49-1.66)]. A similar pattern was observed for severe infection and bone-related conditions. Patients with UC or Crohn's receiving OCS or IS plus OCS were more likely to have emergency department visits, IBD-related hospitalizations/visits/procedures, and gastrointestinal surgery than were patients receiving other therapies. Annualized total medical costs (pharmacy plus hospital service costs) were greatest for anti-TNF plus IS or anti-TNF therapy in both Crohn's and UC. Annualized medical service costs (excluding IBD drug costs) were highest for patients initiating OCS-containing therapies [Crohn's: OCS, $27,041 (24,882-29,200) and OCS plus IS, $23,332 (19,889-26,775); UC: OCS, $19,659 (17,977-21,340)]. CONCLUSION: Although biologic therapies have higher pharmacy costs, treatment decisions should consider the increased AE risks and long-term MRU costs associated with chronic use of OCS-containing therapies.

BACKGROUND: About one third of patients with diffuse large B-cell lymphoma (DLBCL) relapse after receiving first-line (1L) treatment of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Relapsed patients may then be eligible for second-line (2L) therapy. The study's objective was to examine health care use and costs among treated patients with DLBCL receiving 2L therapy versus those without relapse. MATERIALS AND METHODS: We analyzed Truven Health MarketScan® claims data between 2006 and 2015. Patients (≥18 years of age) had ≥1 DLBCL claim from 1 year before to 90 days after beginning 1L therapy, and comprised those without 2L treatment for ≥2 years (cured controls) versus those who initiated non-R-CHOP chemotherapy after discontinuing 1L therapy (2L cohort). 2L patients were further subgrouped: hematopoietic stem cell transplant (HSCT [yes/no]) and time of relapse (months between 1L and 2L): early (≤3), mid (4-12), and late (>12) relapse. The primary outcome was 1- and 2-year health care costs. Hospitalization rate and length of stay were also measured. RESULTS: A total of 1,374 patients with DLBCL received R-CHOP and fulfilled all criteria: 1,157 cured controls and 217 2L patients (87 early-relapse, 66 mid-relapse, 64 late-relapse). Twenty-eight percent of 2L patients received HSCT. Charlson Comorbidity Index/mortality risk was higher for 2L patients (4.2 [SD: 3.0]) versus controls (3.8 [2.6]; p = .039), as were yearly costs (Year 1: $210,488 [$172,851] vs. $25,044 [$32,441]; p < .001 and Year 2: $267,770 [$266,536] vs. $42,272 [$49,281]; p < .001). HSCT and chemotherapy were each significant contributors of cost among 2L patients. CONCLUSION: DLBCL is resource intensive, particularly for 2L patients. Great need exists for newer, effective therapies for DLBCL that may save lives and reduce costs. IMPLICATIONS FOR PRACTICE: This study identified multiple important drivers of cost in the understudied population of patients with diffuse large B-cell lymphoma (DLBCL) receiving second-line (2L) treatment. Such drivers included hematopoietic stem cell transplant (HSCT) and chemotherapy. Even though HSCT is currently the only curative therapy for DLBCL, less than one third of patients receiving 2L and subsequent treatment underwent transplant, which indicates potential underuse. The variation in chemotherapy regimens suggested a lack of consensus for best practices. Further research focusing on newer and more effective treatment options for DLBCL has the potential to decrease mortality, in addition to reducing the extensive costs related to therapy options such as transplant.

BACKGROUND: Hematopoietic stem-cell transplantation (HSCT) requires highly specialized, resource-intensive care. Myeloablative conditioning regimens used before HSCT generally require inpatient stays and are more intensive than other preparative regimens, and may therefore be more costly. OBJECTIVE: To estimate the costs associated with inpatient HSCT according to the type of the conditioning regimen used and other potential contributors to the overall cost of the procedure. METHOD: We used data from the Truven Health MarketScan insurance claims database to analyze healthcare costs for pediatric (age <18 years) and adult (age ≥18 years) patients who had autologous or allogeneic inpatient HSCT between January 1, 2010, and September 23, 2013. We developed an algorithm to determine whether conditioning regimens were myeloablative or nonmyeloablative/reduced intensity. RESULTS: We identified a sample of 1562 patients who had inpatient HSCT during the study period for whom the transplant type and the conditioning regimen were determinable: 398 patients had myeloablative allogeneic HSCT; 195 patients had nonmyeloablative/reduced-intensity allogeneic HSCT; and 969 patients had myeloablative autologous HSCT. The median total healthcare cost at 100 days was $289,283 for the myeloablative allogeneic regimen cohort compared with $253,467 for the nonmyeloablative/reduced-intensity allogeneic regimen cohort, and $140,792 for the myeloablative autologous regimen cohort. The mean hospital length of stay for the index (first claim of) HSCT was 35.6 days in the myeloablative allogeneic regimen cohort, 26.6 days in the nonmyeloablative/reduced-intensity allogeneic cohort, and 21.8 days in the myeloablative autologous regimen cohort. CONCLUSION: Allogeneic HSCT was more expensive than autologous HSCT, regardless of the regimen used. Myeloablative conditioning regimens led to higher overall costs than nonmyeloablative/reduced-intensity regimens in the allogeneic HSCT cohort, indicating a greater cost burden associated with inpatient services for higher-intensity preparative conditioning regimens. Pediatric patients had higher costs than adult patients. Future research should involve validating the algorithm for identifying conditioning regimens using clinical data.
RESUMEN
Myelodysplastic syndromes (MDS) are characterized by ineffective hematopoiesis resulting in refractory cytopenias. Red blood cell (RBC) transfusions can improve anemia; however, prolonged transfusion dependence (TD) is associated with increased morbidity and mortality. Disease-modifying therapy (DMT) for MDS can reduce transfusion requirements, although the optimum timing of DMT initiation is unclear. This retrospective study analyzed linked SEER registry and Medicare claims (2006-2012) to estimate the impact of DMT-initiation (azacitidine, decitabine, or lenalidomide) timing (≤ 3 vs.>3months from start of TD) on the likelihood of achieving transfusion independence (TI) among 508 TD patients with MDS. Mean time to DMT was 28days for early initiators (n=351) and 187days for late initiators (n=157). Fewer early initiators used erythropoiesis-stimulating agents before achieving TI versus late initiators (61.5% vs. 73.9%; P=0.007). In multivariate analyses, early DMT initiation predicted TI achievement (HR, 1.69; P<0.001); patients who met minimum active therapy-exposure requirements were more likely to achieve TI (HR, 2.12; P<0.001). Higher rates of TI were associated with reduced time between onset of TD and DMT initiation. Similarly, patients meeting the minimum treatment-exposure threshold had higher TI rates.

OBJECTIVE: The aim of this study was to characterize treatment patterns and burden of pancreatic neuroendocrine tumors (PNET). METHODS: Using 2 claims databases, we identified patients with PNET initiating targeted therapy (everolimus, sunitinib) or chemotherapy from 2009 to 2012. The first targeted/cytotoxic therapy was considered index treatment. Treatment patterns were graphically evaluated from index treatment initiation until enrollment or study end, whichever occurred first. Disease burden was examined by index group for first follow-up year. RESULTS: In treatment pattern analyses (582 newly treated patients with PNET), 72.2% received chemotherapy index treatment, 16.2% everolimus, and 11.7% received sunitinib. Median index treatment duration was 242, 146, and 126 days for everolimus, sunitinib, and cytotoxics (P < 0.01). Sunitinib initiators switched most often followed by everolimus and cytotoxic initiators. In disease burden analyses, 338 patients met inclusion criteria, with mean age of 54.5 (standard deviation, 9.9) years, 45.6% were female, and there were no significant between-group differences. Targeted therapy initiators had more prior somatostatin analog use versus cytotoxics (53.4% vs 25.1%, P < 0.001); 72.5% had comorbidities after treatment initiation; 42.9% had 1 or more inpatient hospitalization; and 47.9% had 1 or more emergency department visit. CONCLUSIONS: Pancreatic neuroendocrine tumor treatment patterns varied; cytotoxics were more often used as early therapy than targeted agents, but for less time. Patients had high health care utilization, irrespective of treatment, potentially from burdensome symptoms and comorbidities.
