Comparability of European League Against Rheumatology-Recommended Pharmacological Treatments of Oral Ulcers Associated with Behçet's Disease: A Systematic Literature Review of Randomized Controlled Trials.

OBJECTIVE: Oral ulcers are the cardinal manifestation in Behçet's disease (BD). The 2018 European League Against Rheumatism (EULAR) recommendations describe treatments for BD-associated oral ulcers with mucocutaneous involvement; however, little comparative effectiveness information for these agents is available. In the absence of head-to-head trials, an indirect treatment comparison (ITC) could provide useful evidence regarding comparative effectiveness of BD treatments. The purpose of this study was to conduct a comparative systematic literature review (SLR) and similarity assessment of randomized controlled trials (RCTs) investigating the oral ulcer-related efficacy outcomes of EULAR-recommended treatments for BD-associated oral ulcers to determine the feasibility of an ITC. METHODS: An SLR was performed to identify relevant RCTs indexed in MEDLINE/Embase before May 29, 2019. RCT similarities for the ITC were assessed based on a step-wise process recommended by the International Society for Pharmacoeconomics and Outcomes Research. RESULTS: In total, 317 articles were identified, of which 14 RCTs, reflecting 11 EULAR-recommended treatments, were evaluated in a similarity assessment. Number of oral ulcers, resolution of oral ulcers, and healing time for oral ulcers were identified as the possible oral ulcer-related outcomes. After completing the similarity assessment of these outcomes, it was determined that a robust ITC was infeasible for the three oral ulcer-related outcomes due to heterogeneity in outcomes reporting, study design, and/or patient characteristics. More broadly, the results underscore the need for and consistent use of standardized measures for oral ulcer outcomes to facilitate comparative research. CONCLUSION: In the absence of head-to-head RCTs and infeasibility of quantitative ITC, comparative assessments for BD-associated oral ulcers are limited, including comparative effectiveness and cost-effectiveness evaluations. Healthcare decision-makers must continue to base treatment decisions on the extent and strength of available evidence (eg, robust RCTs), clinical guidelines, real-world experience, and patient considerations.

Patients with Idiopathic Membranous Nephropathy: A Real-World Clinical and Economic Analysis of U.S. Claims Data.

BACKGROUND: Membranous nephropathy (MN) is a common cause of nephrotic syndrome in nondiabetic adults. Approximately one third of patients with MN progress to end-stage renal disease (ESRD), while others may be successfully treated to remission. Patients with MN represent a high-risk population for whom management strategies can alter and improve outcomes. Currently, there is little real-world evidence regarding the burden of MN on health plans. OBJECTIVES: To (a) characterize clinical and economic outcomes during a 1-year time frame among a prevalent cohort of patients with MN and (b) compare the 5% of patients incurring the highest cost with the remaining 95%. METHODS: A retrospective analysis of commercially insured patients was conducted using MarketScan administrative health care claims data from January 1, 2012, to December 31, 2015. Patients were aged ≥ 18 years, enrolled In a fee-for-service plan, and had ≥ 2 medical claims for an MN diagnosis (ICD-9-CM codes 581.1, 582.1, and 583.1). Diagnoses indicating clear secondary causes were excluded wherever possible. Demographics were determined as of the first diagnosis date; clinical characteristics (e.g., MN-specific therapy, complications, and procedures), health care resource utilization (HCRU; inpatient, outpatient including other outpatient and emergency department [ED], and prescriptions), and costs were evaluated for 1 year following MN diagnosis. Total costs and cost distribution (2017 U.S. dollars) were examined using plan-paid and patient-paid amounts. The 95th percentile was used to categorize and compare the subcohorts: high-cost cohort (HCC) patients (top 5%) and non-high-cost cohort (NHCC) patients (the remaining 95%). Descriptive analyses, chi-square tests, and Wilcoxon rank-sum tests were conducted. RESULTS: 2,689 patients were identified (60.0% male, mean age = 46.4 years). Severity and advanced disease were observed In a higher proportion of HCC patients (n = 134) versus NHC patients (n = 2,555) via adverse health outcomes, procedures, and immunosuppressant use. HCC patients used significantly more resources on average than NHCC patients (additional use): 1.7 inpatient, 1.2 ED, and 4.8 outpatient office visits; 15 prescriptions; and 64.8 other outpatient visits (i.e., outpatient, hospital, and ESRD facilities). Total MN-related cost and mean (SD) cost per patient were $123.2 million and $45,814 ($101,353); HCC patients accounted for 43.7% of total costs for a mean cost per patient of $401,608 versus NHCC patients at 56.3% and mean cost per patient of $27,154. The greatest costs for both groups were related to outpatient visits (HCC = 46.7%; NHCC = 52.8%), inpatient visits (HCC = 27.7%; NHCC = 28.6%), and prescriptions (HCC = 25.7%; NHCC = 18.6%). CONCLUSIONS: Patients with MN are significantly burdened with high disease severity and adverse health outcomes, resulting In substantial HCRU and costs. Health plan cost drivers for MN (HCC and NHCC patients) occurred primarily In the outpatient setting, followed by the inpatient setting and prescriptions. Modifiable aspects preceding progression to advanced renal disease and worse outcomes should be explored to Identify effective interventions and improve resource allocation earlier In the disease pathway, before ESRD.

Outcomes-Based Contracting Experience: Research Findings from U.S. and European Stakeholders.

BACKGROUND: Outcomes-based contracts (OBCs), a type of risk-sharing arrangement (RSA), have emerged as a promising avenue for payers to engage with pharmaceutical manufacturers to share risk and improve patient access to medicines via evaluation of real-world outcomes. OBJECTIVE: To assess the level of recent OBC activity and stakeholder perceptions of these arrangements, as well as the outlook for future OBC activity from a payer and manufacturer perspective in the United States and EU-5 (France, Germany, Italy, Spain, and the United Kingdom). METHODS: Using a structured questionnaire, interviews were conducted with 27 experts, including 14 U.S. payers, 5 EU-5 national payers, and 8 manufacturer pricing/market access executives (4 U.S., 4 EU-5). We also used the University of Washington's Performance Based Risk-Sharing (PBRS) database and other targeted publicly available information. RESULTS: Publicly disclosed information on OBCs understates the level of OBC activity, since many arrangements are confidential. Overall, U.S. and EU-5 interviewees generally expected that 2 to 3 times more OBCs would be implemented in the next 5 years than in the previous 5 years. Key drivers included the introduction of a national OBC framework in Spain, potentially a similar framework in the United Kingdom, a growing sickness fund activity in Germany, and a U.S. movement towards accountable care. Motivation for OBCs varied markedly across markets and stakeholders, with operational feasibility noted as a significant hurdle in the United States and France. Along with improving health outcomes, cost and financial risk reduction were the primary OBC motivators for payers, while potential access or reimbursement gains were key factors for manufacturers. CONCLUSIONS: Using direct input from U.S. and EU-5 payer and pharmaceutical manufacturer decision makers, this research suggests that high OBC growth is expected in the EU-5 and, to a more moderate extent, in the United States, particularly if clear, simpler OBC frameworks can be developed.

Burden of illness among patients with fragile X syndrome (FXS): a Medicaid perspective.

BACKGROUND: Fragile X syndrome (FXS) is an inherited intellectual disability that imposes a substantial clinical and humanistic burden on patients and caregivers. This study aimed to quantify the incremental burden of illness following FXS diagnosis in Medicaid populations. METHODS: A retrospective matched-cohort study was conducted using FL, NJ, MO, IA, and KS Medicaid claims (1997-2012). Patients with FXS were matched 1:5 to a comparison group without FXS, based on age, gender, state, and continuous Medicaid coverage. Healthcare resource utilization and costs were compared among cohorts over 1 year following first diagnosis. RESULTS: Overall, 697 patients with FXS were matched to 3485 non-FXS patients. Median age was 12.0 years; 82% were male. Newly diagnosed FXS patients were younger (median age: 7.0 years). During the follow-up, patients with FXS had significantly higher medication use, medical procedure use, medical specialist visits, and associated costs than the non-FXS comparison group. One-fourth of FXS patients filled prescriptions for stimulants, antipsychotics, or anticonvulsants; 25% of patients with FXS had speech and language therapy and 39% had physical therapy (versus 9%, 4% and 8%, respectively, for the comparison group). At least 44% of FXS patients visited a neurologist, cardiologist, otolaryngologist, or gastroenterologist; 92% of patients with FXS had an outpatient visit, 35% had an emergency room visit, and 34% used home services (compared to 31%-32%, 64%, 27%, and 10%, respectively, for the comparison group) (all p < 0.05). Patients with FXS had an incremental annual total healthcare cost of $33,409 (2012$) per person relative to the comparison group, while newly diagnosed FXS patients had incremental total annual healthcare costs of $17,617 (2012$) per person. CONCLUSIONS: Both established and newly diagnosed FXS were associated with significantly increased use of multiple medications and medical services, and increased healthcare costs. Treatments that could help reduce this disease burden are urgently needed.

Costs and health care resource utilization among chronic obstructive pulmonary disease patients with newly acquired pneumonia.

BACKGROUND: Patients with chronic obstructive pulmonary disease (COPD) are at increased risk for lung infections and other pathologies (eg, pneumonia); however, few studies have evaluated the impact of pneumonia on health care resource utilization and costs in this population. The purpose of this study was to estimate health care resource utilization and costs among COPD patients with newly acquired pneumonia compared to those without pneumonia. METHODS: A retrospective claims analysis using Truven MarketScan(®) Commercial and Medicare databases was conducted. COPD patients with and without newly acquired pneumonia diagnosed between January 1, 2004 and September 30, 2011 were identified. Propensity score matching was used to create a 1:1 matched cohort. Patient demographics, comorbidities (measured by Charlson Comorbidity Index), and medication use were evaluated before and after matching. Health care resource utilization (ie, hospitalizations, emergency room [ER] and outpatient visits), and associated health care costs were assessed during the 12-month follow-up. Logistic regression was conducted to evaluate the risk of hospitalization and ER visits, and gamma regression models and two-part models compared health care costs between groups after matching. RESULTS: In the baseline cohort (N=467,578), patients with newly acquired pneumonia were older (mean age: 70 versus [vs] 63 years) and had higher Charlson Comorbidity Index scores (3.3 vs 2.6) than patients without pneumonia. After propensity score matching, the pneumonia cohort was nine times more likely to have a hospitalization (odds ratio; 95% confidence intervals [CI] =9.2; 8.9, 9.4) and four times more likely to have an ER visit (odds ratio; 95% CI =4.4; 4.3, 4.5) over the 12-month follow-up period compared to the control cohort. The estimated 12-month mean hospitalization costs ($14,353 [95% CI: $14,037-$14,690]), outpatient costs ($6,891 [95% CI: $6,706-$7,070]), and prescription drug costs ($1,104 [95% CI: $1,054-$1,142]) were higher in the pneumonia cohort than in the control cohort. CONCLUSION: This study demonstrated elevated health care resource use and costs in patients with COPD after acquiring pneumonia compared to those without pneumonia.
