RESUMO
BACKGROUND: The objective was to report critical respiratory syncytial virus (RSV)-related epidemiological and healthcare resource utilization measures among Japanese children stratified by gestational and chronological age groups. METHODS: The JMDC (formerly the Japan Medical Data Center) was used to retrospectively identify infants with or without RSV infection (beginning between 1 February 2011 and 31 January 2016, with follow-up through 31 December 2017). The incidence of RSV medically attended lower respiratory tract infection (MALRI) was captured by flagging hospitalizations, outpatient, and emergency department/urgent care visits with an RSV diagnosis code during the season. RESULTS: Of 113 529 infants and children identified, 17 022 (15%) had an RSV MALRI (14 590 during the season). The RSV MALRI and hospitalization rates in the first 5 months were 14.3/100 child-years (CY) and 6.0/100 CY, respectively (13.4/100 and 5.8/100 CY for full-term infants and 20/100 and 6.8/100 CY for late preterm infants, respectively). Among those with ≥1 type of MALRI event during the RSV season, >80% of children had it by 24 months of chronological age, although this observation differed by prematurity status. Sixty percent of healthcare resource utilization measures started in the outpatient setting. CONCLUSIONS: This study emphasizes the RSV burden in young children and critically highlights the data needed to make decisions about new preventive strategies.

BACKGROUND: Respiratory syncytial virus (RSV) is the primary cause of respiratory tract infections in infants; however, current burden estimates report only the short-term effects of acute infection. METHODS: Infants with RSV infection and ≥24 months of continuous enrollment were retrospectively identified from the Truven MarketScan database (1 January 2004-30 September 2015). Exposed infants (n = 38 473) were propensity score matched to nonexposed controls (n = 76 825) by baseline characteristics and gestational age. Five-year cumulative all-cause, asthma/wheezing, and respiratory event-related hospitalization rates and physician and emergency department healthcare-resource utilization rates were assessed. RESULTS: During follow-up, RSV-infected cohorts had higher average all-cause cumulative hospitalization rates, compared with controls, with values of 79.9 hospitalizations/100 patient-years (95% confidence interval [CI], 41.7-118.2) for 213 early premature infants (P < .001), 18.2 hospitalizations/100 patient-years (95% CI, .8-35.7) for 397 premature infants (P = .04), 34.2 hospitalizations/100 patient-years (95% CI, 29.1-39.2) for 4446 late premature infants (P < .001), and 16.1 hospitalizations/100 patient-years (95% CI, 14.9-17.4) for 33 417 full-term infants (P < .001). Cumulative rates of physician and emergency department visits were also higher for RSV-infected infants. Asthma/wheezing accounted for 10%-18% of total 5-year physician visits. CONCLUSIONS: Infant RSV infection has a significant long-term healthcare-resource utilization impact across gestational ages for at least 5 years after infection, most of it in the first 2 years. Systematically collecting healthcare-resource utilization data will be important for cost-effectiveness evaluations of RSV interventions in planned or ongoing trials.

BACKGROUND: This study evaluates the long-term respiratory syncytial virus (RSV) burden among preterm and full-term infants in the United States. METHODS: Infants with birth hospitalization claims and ≥24 months of continuous enrollment were retrospectively identified in the Truven MarketScan Commercial Claims and Encounters database for the period 1 January 2004-30 September 2015. Infants with RSV infection in the first year of life (n = 38 473) were matched to controls (n = 76 825), and remaining imbalances in the number of individuals in each group were adjusted using propensity score methods. All-cause, respiratory-related, and asthma/wheezing-related 5-year average cumulative costs were measured. RESULTS: Early premature (n = 213), premature (n = 397), late premature (n = 4446), and full-term (n = 33 417) RSV-infected infants were matched to 424, 791, 8875, and 66 735 controls, respectively. After 2 years since RSV diagnosis, all-cause cumulative costs for RSV-infected infants as compared to those for controls increased by $22 081 (95% confidence interval [CI], -$5800-$42 543) for early premature infants, by $14 034 (95% CI, $5095- $22 973) for premature infants, by $10 164 (95% CI, $8835-$11 493) for late premature infants, and by $5404 (95% CI, $5110-$5698) for full-term infants. The 5-year RSV burden increased to $39 490 (95% CI, $18 217-$60 764), $23 160 (95% CI, $13 002-$33 317),$13 755 (95% CI, $12 097-$15 414), and $6631 (95% CI, $6060-$7202), respectively. The RSV burden was higher when stratified by inpatient and outpatient setting and respiratory-related and asthma/wheezing-related costs. CONCLUSIONS: The RSV burden extends across cost domains and prematurity, with the greatest burden incurred by the second year of follow-up. Findings are useful in determining the cost-effectiveness of RSV therapies in development.

OBJECTIVE: To evaluate the cost-effectiveness of alemtuzumab compared with fingolimod, natalizumab, ocrelizumab, and generic glatiramer acetate 20 mg among patients with relapsing multiple sclerosis (RMS) in the United States. STUDY DESIGN: Markov model with annual periods from payer perspective. METHODS: The modeled population represented pooled patients from the CARE-MS I and II trials. Therapies' comparative efficacy at reducing relapses and slowing disability worsening was obtained from network meta-analyses. Safety information was extracted from package inserts. Withdrawal rates, treatment waning, resource use, cost, and utility inputs were derived from published studies and clinical expert opinion. To project the natural history of disease worsening, data from the British Columbia cohort was used. RESULTS: Alemtuzumab dominated comparators by accumulating higher total quality-adjusted life-years (QALYs) (8.977) and lower total costs ($421 996) compared with fingolimod (7.955; $1 085 814), natalizumab (8.456; $1 048 599), ocrelizumab (8.478; $908 365), and generic glatiramer acetate (7.845; $895 661) over a 20-year time horizon. Alemtuzumab's dominance was primarily driven by savings in treatment costs because alemtuzumab has long-term duration of response and is initially administered as 2 annual courses, with 36.1% of patients requiring retreatment over 5 years, whereas comparators are used chronically. In model scenarios where alemtuzumab's long-term duration of response was assumed not to hold and therapy had to be administered annually, probabilistic sensitivity analyses showed that alemtuzumab remained cost-effective versus ocrelizumab at a willingness-to-pay threshold of $100 000/QALY in 74% to 100% of model runs. CONCLUSIONS: Alemtuzumab was a cost-effective therapy. Model results should be used to optimize clinical and managed care decisions for effective RMS treatment.

BACKGROUND: To help broaden the use of machine-learning approaches in health services research, we provide an easy-to-follow framework on the implementation of random forests and apply it to identify quality of care (QC) patterns correlated with treatment receipt among Medicare disabled patients with hepatitis C virus (HCV). METHODS: Using Medicare claims 2006-2009, we identified 1936 patients with 6 months continuous enrollment before HCV diagnosis. We ran a random forest on 14 pretreatment QC indicators, extracted the forest's representative tree, and aggregated its terminal nodes into 4 QC groups predictive of treatment. To explore determinants of differential QC receipt, we compared patient-level and county-level (linked AHRF data) characteristics across QC groups. RESULTS: The strongest predictors of treatment included "liver biopsy," "HCV genotype testing," "specialist visit," "HCV viremia confirmation," and "iron overload testing." High QC [n=360, proportion treated (pt)=33.3%] was defined for patients with at least 2 from the above-mentioned metrics. Good QC patients (n=302, pt=12.3%) had either "HCV genotype testing" or "specialist visit," whereas fair QC (n=282, pt=7.1%) only had "HCV viremia confirmation." Low QC patients (n=992, pt=2.5%) had none of the selected metrics. The algorithm accuracy of predicting treatment was 70% sensitivity and 78% specificity. HIV coinfection, drug abuse, and residence in counties with higher supply of hospitals with immunization and AIDS services correlated with lower QC. CONCLUSIONS: Machine-learning techniques could be useful in exploring patterns of care. Among Medicare disabled HCV patients, the receipt of more QC indicators was associated with higher treatment rates. Future research is needed to assess determinants of differential QC receipt.

OBJECTIVE: Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate licensed for the treatment of relapsed/refractory Hodgkin lymphoma (rrHL) following autologous stem cell transplant (ASCT) or at least two prior therapies when ASCT or multiagent chemotherapy is not an option. The objective of this study was to describe real-world outcomes with BV in patients with rrHL considered ASCT ineligible or who refuse ASCT. METHODS: This was a retrospective medical chart review study that enrolled patients ≥18 years old who were initially diagnosed with HL between January 1, 2008 and June 30, 2014, considered ASCT ineligible, and treated in routine care with BV for progressive disease after multidrug chemotherapy regimens. Clinical outcomes included best response to treatment, progression-free survival (PFS), overall survival (OS), and adverse events. RESULTS: A total of 136 patients were included, with a median age of 70 years at initial HL diagnosis. The most common reasons for ASCT ineligibility were comorbidities (74%) and age (57%). Overall response rate was 74%, and PFS and OS were 15.1 and 17.8 months, respectively. Peripheral neuropathy was observed in 9.6% of patients. CONCLUSION: The results of this study provide real-world evidence on the feasibility and effectiveness of BV in elderly or frail ASCT-ineligible patients with rrHL in a real-world setting.

OBJECTIVE: To determine the effectiveness and cost savings of a real-world, continuous, pharmacist-delivered service with an employed patient population with diabetes over a 5-year period. SETTING: The Patients, Pharmacists Partnerships (P3 Program) was offered as an "opt-in" benefit to employees of 6 public and private self-insured employers in Maryland and Virginia. Care was provided in ZIP code-matched locations and at 2 employers' worksites. PRACTICE DESCRIPTION: Six hundred two enrolled patients with type 1 and 2 diabetes were studied between July 2006 and May 2012 with an average follow-up of 2.5 years per patient. Of these patients, 162 had health plan cost and utilization data. A network of 50 trained pharmacists provided chronic disease management to patients with diabetes using a common process of care. Communications were provided to patients and physicians. PRACTICE INNOVATION: Employers provided incentives for patients who opted in, including waived medication copayments and free diabetes self-monitoring supplies. The service was provided at no cost to the patient. A Web-based, electronic medical record that complied with the Health Insurance Portability and Accountability Act helped to standardize care. Quality assurance was conducted to ensure the standard of care. EVALUATION: Glycosylated hemoglobin (A1c), blood pressure, and total health care costs (before and after enrollment). RESULTS: Statistically significant improvements were shown by mean decreases in A1c (-0.41%, P <0.001), low-density lipoprotein levels (-4.7 mg/dL, P = 0.003), systolic blood pressure (-2.3 mm Hg, P = 0.001), and diastolic blood pressure (-2.4 mm Hg, P <0.001). Total annual health care costs to employers declined by $1031 per beneficiary after the cost of the program was deducted. This 66-month real-world study confirms earlier findings. Employers netted savings through improved clinical outcomes and reduced emergency and hospital utilization when comparing costs 12 months before and after enrollment. CONCLUSION: The P3 program had positive clinical outcomes and economic outcomes. Pharmacist-provided comprehensive medication therapy management services should be included as a required element of insurance offered by employers and health insurance exchanges.

UNLABELLED: Patient- and county-level characteristics associated with advanced liver disease (ALD) at hepatitis C virus (HCV) diagnosis were examined in three Medicare cohorts: (1) elderly born before 1945; (2) disabled born 1945-1965; and (3) disabled born after 1965. We used Medicare claims (2006-2009) linked to the Area Health Resource Files. ALD was measured over the period of 6 months before to 3 months after diagnosis. Using weighted multivariate modified Poisson regression to address generalizability of findings to all Medicare patients, we modeled the association between contextual characteristics and presence of ALD at HCV diagnosis. We identified 1,746, 3,351, and 592 patients with ALD prevalence of 28.0%, 23.0%, and 15.0% for birth cohorts 1, 2, and 3. Prevalence of drug abuse increased among younger birth cohorts (4.2%, 22.6%, and 35.6%, respectively). Human immunodeficiency virus coinfection (prevalence ratio [PR] = 0.63; 95% confidence interval [CI]: 0.50-0.80; P = 0.001), dual Medicare/Medicaid eligibility (PR = 0.89; 95% CI: 0.80-0.98; P = 0.017), residence in counties with higher median household income (PR = 0.82; 95% CI: 0.71-0.95; P = 0.008), higher density of primary care providers (PR = 0.84; 95% CI: 0.73-0.98; P = 0.022), and more rural health clinics (PR = 0.90; 0.81-1.01; P = 0.081) were associated with lower ALD risk. End-stage renal disease (PR = 1.41; 95% CI: 1.21-1.63; P = 0.001), alcohol abuse (PR = 2.57; 95% CI: 2.33-2.84; P = 0.001), hepatitis B virus (PR = 1.32; 95% CI: 1.09-1.59; P = 0.004), and Midwest residence (PR = 1.22; 95% CI: 1.05-1.41; P = 0.010) were associated with higher ALD risk. Living in rural counties with high screening capacity was protective in the elderly, but associated with higher ALD risk among the disabled born 1945-1965. CONCLUSIONS: ALD prevalence patterns were complex and were modified by race, elderly/disability status, and the extent of health care access and screening capacity in the county of residence. These study results help inform treatment strategies for HCV in the context of coordinated models of care.

Specialty-related cost differences for the treatment of nonmelanoma skin cancer (NMSC) have been previously reported but without taking into account confounding factors. Using a previously validated model for NMSC episode of care, episodes were identified in the Medicare Current Beneficiary Survey claims 2005 to 2007. A γ regression with log link model estimated the effect of physician exposure on total episode costs controlling for sociodemographics, health status and comorbidities, treatment and repair procedures, as well as tumor size and location. Treatment-related NMSC episodes (1285) were identified. In the unadjusted model, episodes managed by generalists were associated with 36% lower costs, those by otolaryngologists/plastic surgeons with 82% higher costs, and those by multiple specialists with 111% higher costs, compared to dermatologists. Cost differences were substantially reduced in the adjusted regression analysis; compared to dermatologists, episodes managed by generalists were associated with 20% lower costs (P < 0.0001), whereas otolaryngologists/plastic surgeons and multiple specialists were associated with 20% (P < 0.01) and 11% (P = 0.02) higher costs, respectively. Overall, comparison between unadjusted and adjusted estimates suggests that controlling for severity and treatment modalities explains most of the specialty cost differences. Our estimates could be subject to residual confounding due to selection bias and the limitations to using claims data to characterize an NMSC episode of care. Adjusting for the severity of the disease and other confounders, our study found much smaller specialty-related cost differences for the management of NMSC than previously reported unadjusted estimates.

OBJECTIVE: We evaluated the effect of an educational intervention administered to patients or/and physicians on the reduction in HbA(1c) and achieving diabetic control in a high-risk primarily Black inner-city population. METHODS: The study was designed as a four-arm randomized clinical trial where an educational program on diabetes was offered to physicians only, patients only, and both physicians and their patients, while the fourth arm did not receive any instruction. We built regression models at 24 months of follow-up to assess the likelihood of reaching glycemic goal as well as to measure the absolute reduction in HbA(1c) controlling for arm assignment, insulin use, race, age, sex, smoking, insulin use, and having achieved blood pressure control. RESULTS: Between April 2005 and July 2007, there were 823 patients randomized into the study. In multivariate analyses, the intervention group in which only patients received education showed a trend toward achieving a significant mean reduction in HbA(1c) with 49% (P = .06) higher odds of reaching glycemic control and .12 (P = .06) greater absolute percentage point drop in HbA(1c) compared to the no education group. CONCLUSION: Although our study reports positive results, it warrants a special emphasis on the behavior of the patient. Study results bring attention to disease management programs such as peer support networks that empower the patients that shift some of the responsibility to them.

INTRODUCTION: Deucravacitinib demonstrated superior efficacy to apremilast in patients with moderate to severe plaque psoriasis in the POETYK PSO-1 and PSO-2 clinical trials. In the study reported here, we aimed to determine the overall 52-week cumulative clinical benefit of treatment initiated with deucravacitinib versus apremilast and to compare the 52-week cumulative benefit of initiating and staying on deucravacitinib versus initiating apremilast and continuing or switching to deucravacitinib at week 24 of treatment. METHODS: This post hoc analysis of POETYK PSO-1 data (ClinicalTrials.gov identifier: NCT03624127) determined the cumulative clinical benefit of deucravacitinib 6 mg once daily and apremilast 30 mg twice daily in adults with moderate to severe plaque psoriasis. Patients treated with apremilast who did not achieve a 50% reduction in the Psoriasis Area and Severity Index (PASI 50) at week 24 were switched to deucravacitinib. The cumulative clinical benefit of deucravacitinib versus apremilast over 52 weeks was based on cumulative measures of ≥ 75% improvement from baseline in PASI score (PASI 75) and the proportion of patients with a static Physician Global Assessment score of 0 or 1 (sPGA 0/1). Ratios of area under the curve estimates between treatments were calculated and compared based on analysis of covariance regression models. RESULTS: Patients initiating deucravacitinib (N = 332) had a greater cumulative benefit as measured by the PASI 75 and sPGA 0/1 than those initiating apremilast (N = 168). Over 52 weeks, those initiating deucravacitinib experienced 50% more benefit as measured by PASI 75 and 58% more benefit as measured by sPGA 0/1 than those initiating apremilast. Results were consistent with the primary analysis when patients were classified by prior systemic and prior biologic therapy exposure. CONCLUSION: Results from this analysis corroborate the primary efficacy analysis supporting the use of deucravacitinib compared with apremilast for moderate to severe plaque psoriasis, regardless of prior systemic or biologic use.
RESUMO
OBJECTIVES: To examine cumulative survival and Medicaid-paid expenses associated with multiple courses of transarterial chemoembolization (TACE) as primary treatment for hepatocellular carcinoma (HCC). METHODS: Medicare enrollees diagnosed with primary HCC from 2000 to 2007, ever treated with TACE, but not transplant/resection, followed through 2009 by using the Surveillance, Epidemiology and End-Results Program and linked Medicare databases. Cumulative all-cause/HCC-related survival was estimated by using multivariate Cox proportional hazards models stratified by the total number of TACE treatments. Multivariate weighted Cox regressions estimated the average risk of mortality faced with nonproportional hazards. Lin's inverse probability-weighted least squares regression method estimated cumulative Medicare expenditures adjusted for censoring and covariates. RESULTS: Of 1228 patients, 34% were stage 1, 16% stage 2, 19% stage 3, 6% stage 4, and 26% unstaged. About 44% were aged 65 to 75 years, 69% were men, and 72% were Caucasian. Over half (57%) of the patients received one course, 24% two, 11% three, and 8% four courses of TACE. One-course patients incurred an average $74,788 (95% confidence interval [CI] $71,890-$77,686), two-course patients $101,126 (95% CI $94,395-$107,856), three-course patients $111,776 (95% CI $101,931-$121,621), and four-plus-course patients $148,878 (95% CI $136,346-$161,409). One-course patients lived (all-cause) an average 1.86 (95% CI 1.82-1.90), two-course patients 2.09 (95% CI 2.05-2.13), three-course patients 2.81 (95% CI 2.66-2.97), and four-plus-course patients 3.06 (95% CI 2.95-3.18) years after diagnosis. Average risk of all-cause mortality was not significantly different between one/two courses or three/four-plus courses. CONCLUSIONS: Cumulative Medicare expenditures nearly doubled from one-course to four-plus-course patients. On average, four-plus-course patients lived over one more year than did one-course patients. Physician/patient decisions should be balanced with consideration of efficient use of limited resources, but payer's intervention in physician discretion may not be important in this setting.

INTRODUCTION: Evidence on the comparison of treatments for hepatorenal syndrome-acute kidney injury (HRS-AKI) in a US population is limited. An indirect comparison of terlipressin plus albumin vs midodrine and octreotide plus albumin (MO) may provide further insight into treatment efficacy. METHODS: Cohorts of patients treated for HRS-AKI characterized by inclusion of patients with serum creatinine (SCr) <5 mg/dL and baseline acute-on-chronic liver failure grades 0-2 and exclusion of patients listed for transplant if model for end-stage liver disease scores ≥35 were pooled from (i) the CONFIRM and REVERSE randomized controlled trials (N = 159 meeting eligibility criteria from N = 216 overall, treated with terlipressin) and (ii) a retrospective review of medical records from 10 US tertiary hospitals (2016-2019; N = 55 treated with MO meeting eligibility criteria from N = 200 overall). The primary end point comparing the 2 cohorts was HRS reversal defined as achieving SCr ≤1.5 mg/dL at least once during the treatment. Covariate balancing propensity scoring was used to adjust for differences in baseline characteristics. RESULTS: HRS-AKI reversal was achieved in 52.35% of terlipressin-treated patients compared with 20% of MO-treated patients (adjusted mean difference 32.35%, 95% confidence interval [CI] 17.40-47.30, P < 0.0001). Terlipressin-treated patients had increased overall survival (adjusted hazard ratio 0.57, 95% CI 0.35-0.93, P = 0.02) but similar transplant-free survival (adjusted hazard ratio 0.79, 95% CI 0.53-1.17, P = 0.24). Achievement of HRS-AKI reversal was associated with increased OS and TFS regardless of treatment ( P < 0.001). DISCUSSION: Consistent with prior reports, terlipressin plus albumin is more effective in improving kidney function and achieving HRS-AKI reversal than MO plus albumin based on indirect comparison in a US population.

PURPOSE: Advanced/recurrent endometrial cancer is associated with poor long-term outcomes. Clinical studies of novel regimens are ongoing, but given that data on overall survival (OS) take a long time to mature, surrogate end points are often used to support clinical-research interpretation. The aim of this study was to explore the correlation between progression-free survival (PFS)/time to progression (TTP) and OS across multiple time points in the first-line treatment of advanced/recurrent endometrial cancer. METHODS: This study comprised meta-analyses of Phase 2/3 randomized, controlled trials of first-line treatments in patients with advanced primary or first-recurrent endometrial cancer identified via systematic literature review. The strength of the surrogacy relationship was assessed by correlation analyses (estimated with Spearman and Pearson correlation coefficients) and weighted linear regression. FINDINGS: Data from 15 studies were included. PFS and TTP (TTP was reported in one study only) were highly correlated with future OS at multiple time points (Spearman values, 0.83-0.90; Pearson values, 0.86-0.93), suggesting that a change in PFS/TTP would likely be correlated with a change in OS in the same direction. On weighted linear regression, a 10% increase in PFS/TTP probability was significantly associated with a 9.3% to 13.3% increase in the probability of future OS. The strong positive association between PFS/TTP and OS was supported by findings from sensitivity analyses based on identified sources of interstudy heterogeneity. IMPLICATIONS: PFS/TTP is a good potential candidate for predicting long-term OS outcomes in trials of first-line treatment in patients with advanced/recurrent endometrial cancer. The findings from this report may help to inform health-authority and clinical decision makers that PFS/TTP improvements are likely to translate into subsequent OS improvements once data mature.

INTRODUCTION: Deucravacitinib, an oral tyrosine kinase 2 (TYK2) inhibitor, is approved in the United States to treat adults with moderate-to-severe plaque psoriasis (PsO). This study compared the long-term efficacy of deucravacitinib and adalimumab using results from long-term extension (LTE) trials. METHODS: Open-label LTE trials were identified for an indirect treatment comparison (deucravacitinib: POETYK PSO-LTE [NCT04036435]; adalimumab: REVEAL extension [NCT00195676]). To ensure study design comparability, patients initially randomized to placebo and switched to deucravacitinib or adalimumab after week 16 were compared. The primary outcome was an ≥ 75% reduction in Psoriasis Area and Severity Index score (PASI 75) at week 112 postrandomization. Secondary outcomes were PASI 75 at week 52 and an ≥ 90% reduction in PASI score (PASI 90) at weeks 52 and 112. Missing PASI data were imputed. A matching-adjusted indirect comparison was conducted; individual patient-level data from POETYK PSO-LTE were reweighted to balance baseline characteristics with those from the REVEAL extension. RESULTS: Before reweighting, on average, patients in the POETYK PSO-LTE (N = 329) versus the REVEAL (N = 345) extension were older, had a lower body weight, received more prior systemic treatments, and had higher baseline PASI scores and week 16 placebo PASI 75 and PASI 90 response rates. Following reweighting, adjusted week 112 PASI 75 response rates were significantly higher for deucravacitinib versus adalimumab (67.2% vs. 54.0%; mean difference [95% CI], 13.2 [4.0-22.5] percentage points). Deucravacitinib had a numerically higher adjusted week 112 PASI 90 response rate (41.3% vs. 34.0%; mean difference [95% CI], 7.3 [-2.0 to 16.7] percentage points). The treatments had similar week 52 adjusted PASI 75 and PASI 90 response rates. CONCLUSION: In this interim analysis, adults with moderate to severe PsO had higher long-term response rates at 2 years when treated with deucravacitinib versus adalimumab. Deucravacitinib response rates remained stable whereas adalimumab response rates declined in year 2.
Plaque psoriasis is an inflammatory disease that causes red, itchy, dry patches (called plaques) on the skin. The disease cannot be cured, but the symptoms can be treated. Deucravacitinib and adalimumab are two treatments approved for use in adults with moderate to severe plaque psoriasis; deucravacitinib is an oral medication and adalimumab is injected with a needle under the skin. Each treatment has proven its efficacy compared with placebo (a pill or injection with no active effect) in separate clinical trials, but because no two clinical trials are exactly alike, the results cannot be accurately compared. Matching-adjusted indirect comparison is a method used to compare the results of one clinical trial with those of another when a direct comparison is not possible; characteristics from the patients in one trial are made to match the patient population in the other trial, and the adjusted results are compared. We performed a matching-adjusted indirect comparison of an open-label extension trial of deucravacitinib with an open-label extension trial of adalimumab to study the long-term efficacy of each treatment. At 1 year of treatment, we observed that similar proportions of patients receiving each treatment achieved a 75% or 90% improvement from their baseline Psoriasis Area and Severity Index score, called PASI 75 or PASI 90, respectively. At 2 years of treatment, similar proportions achieved PASI 90, but the proportion of patients receiving deucravacitinib who achieved PASI 75 was greater than that of patients receiving adalimumab.
RESUMO
Background: The objective of this study was to estimate the long-term healthcare utilization and cost burden of RSV by chronological age of diagnosis (Year 1, Year 2 and Years 3-5 cohorts) as well as by gestational age at birth in Japan. Methods: The JMDC database was used to retrospectively identify RSV and control patients between February 1, 2011 and January 31, 2016 and follow them through December 31, 2017. Infants with RSV infection (n = 9028 in Year 1; n = 4929 in Year 2; n = 2004 in Years 3-5) were matched to controls (n = 17,886; n = 9351; n = 3655, respectively) based on gestational age and year and quarter of birth; controls were assigned the index date (ie, diagnosis) of their respective match. Covariate-balancing propensity score weights were employed adjusting for remaining imbalances between cohorts. The main outcomes were average cumulative rates for all-cause, asthma/wheezing, and respiratory-related hospitalizations, physician and urgent care/emergency visits and associated costs (reported as 2018 ¥JPY) over 36-months of follow-up since index. Results: Healthcare utilization was significantly higher among RSV cases for most comparisons. All-cause average differential cost burden was higher for RSV, compared to controls, among the following cohorts: Year 1 full-term (¥277,727); Year 2 preterm (¥530,302), late preterm (¥270,797), full-term (¥238,832); Years 3-5 preterm (¥110,057), late preterm (¥486,670), full-term (¥289,986). While all-cause costs were similar for preterm and late preterm children in the Year 1 cohort, respiratory- and asthma/wheezing-related attributable costs were substantially higher for RSV. Conclusion: RSV infection had a significant long-term health and economic burden among children infected during their first year of life and later in life. Study findings have import for prevention strategies, currently directed at maternal immunization and monoclonal antibodies for preventing primary RSV infections in the first six months of life and beyond but also for older age not targeted currently.
RESUMO
Little is known about the economic burden incurred by out-of-hospital cardiac arrest (OHCA) in the US commercial insurance setting. We used IBM MarketScan Commercial Claims and Encounters Database (January 2014 to March 2019) to identify patients hospitalized with OHCA based on the International Classification of Diseases codes. Patients who survived the initial OHCA episode were stratified by prognosis based on discharge setting and classified into mild (discharged home), moderate (skilled nursing facility), severe (inpatient rehabilitation or long-term hospital), and very severe (hospice) prognosis groups, respectively. Patients were followed up for 12 months after discharge for health care resource utilization and medical costs, which were inflated to year 2020. Overall, 23,512 patients with OHCA hospitalization were identified, of whom 14,667 were <65 years and 60.5% were men. The incidence of OHCA per 100,000 was steady in patients <65 years over the years (17.9 in 2014; 17.5 in 2018) but among those ≥65 years, decreased from 139.7 in 2014 to 111.1 in 2018. Total medical costs 12 months after discharge generally increased with severity of prognosis, with an average for the mild, moderate, and severe prognosis group, respectively, estimated to be $52,746, $100,394, and $130,530 among patients <65 years, and $63,194, $65,794, and $70,973 among those ≥65 years. Costs were lower for those with very severe prognosis ($7,102 for <65 years; $2,553 for ≥65 years), possibly due to high mortality. In conclusion, OHCA continues to pose a substantial clinical and economic burden on patients and the US health care system, which increases with the severity of disease prognosis.

Background: To extend the discussion on the use of real-world evidence (RWE) in conveying the clinical value of treatment beyond trial data, the primary objective of this study was to assess if efficacy gains in progression-free survival (PFS) observed in randomized controlled trials (RCT) correlate with efficacy gains in the real-world setting. For this, we assessed the treatment benefit of three tyrosine kinase inhibitors (TKIs) in aNSCLC. Methods: Using matched cohorts identified in the Flatiron Health database (2011-2020), we mimicked the following cohorts of TKI versus platinum-based chemotherapy (PBC) from the following trials: (1) erlotinib, EURTAC; (2) afatinib, LUX-Lung 3; and (3) crizotinib, PROFILE 1014. Time to treatment discontinuation (TTD) hazard ratio (HR) was used as a proxy for PFS HR, the primary endpoint in the selected RCTs. HRs were calculated via Cox proportional hazard models. Results: Overall, 1,118 patients were included across the three RWE cohorts. Frontline TKI regimens had statistically significantly better real-world TTD than their matched PBC comparator group (HR 0.37, 95% confidence interval [CI] 0.30-0.44 for erlotinib; HR 0.42, 95% CI 0.32-0.55 for afatinib; HR 0.37, 95% CI 0.26-0.53 for crizotinib). The benefit in real-world OS was not different between TKIs and PBC patients, attributed to a high proportion of switching to subsequent therapy. Study findings of relative treatment benefit (HR) for real-world TTD and OS were deemed similar to those for PFS and OS from the pivotal RCTs. Conclusion: The relative treatment effect, measured as real-world TTD HR over the long term, was similar to trial-based PFS HR, implying that the clinical benefit of aNSCLC treatments conveyed in trials translated into the clinical setting. This is important, given that OS data interpretation is limited, even with longer follow-up. Additionally, our RWE analysis endorses TTD as a relevant endpoint to measure clinical benefit.
RESUMO
Purpose: To assess the incremental burden of corneal transplant surgery for US commercially insured patients with Fuchs endothelial corneal dystrophy (FECD) treated with endothelial keratoplasty (EK) compared to controls. Methods: The study design was retrospective cohort using IBM® MarketScan® claims (January 2014-September 2019) and included EK-treated (N=1562) and control patients (N=23,485) having ≥12 months' enrollment before and after diagnosis, who were subsequently matched on select characteristics. The index date was the beginning of the pre-operative period (3 months before EK); synthetic EK index was assigned for controls. All-cause, eye-disease, and complication-related healthcare resource utilization (HCRU) and costs were compared up to 36 months post index. For a small subset of patients, patient data were linked to the Health and Productivity Management supplemental database, which integrates data on productivity loss and disability payments. Results: Matched cohorts included 804 EK-treated and 1453 controls with average age 65.7 years, 1383 (61%) female. Over 12 months of follow-up, all-cause ($41,199 vs $20,222, p<0.001) and eye-disease related costs ($22,951 vs $1389, p<0.001) were higher among EK-treated patients than controls. The cost differential increased additionally by $1000-$2000 per annum by 36 months of follow-up. While balanced at baseline, over follow-up EK-treated patients had higher prevalence of glaucoma, elevated intraocular pressure, cataract, cataract surgery, diagnosis of cornea transplant rejection, retinal edema. By 36 month of follow-up, EK-treated patients had 9 more short-term disability days, resulting in $2992 additional burden of disability payments. Conclusion: This study found a higher cost burden among FECD patients receiving EK treatment versus those who did not. With a shift in management of FECD, cost burden estimates generated in this study could serve as an important benchmark for future studies.
