Network Meta-Analyses of Real-World Evidence: A Systematic Review of Methods

Network meta-analysis (NMA) compares multiple health technologies when there is a lack of direct evidence with randomized controlled trials (RCT) alone. While supplementing RCTs with robust real-world evidence (RWE) in NMAs has become standard practice, NMAs of RWE alone are now being used to gain insights into the patient experience in clinical practice. This SLR aimed to assess the quality of published RWE-only NMAs and evaluate the statistical methods used to account for clinical and statistical heterogeneity. Authors Nambiar S,…

Epidemiology and Real-World Treatment of Chronic Graft-Versus-Host Disease Post Allogeneic Hematopoietic Cell Transplantation: A US Claims Analysis

Chronic Graft-Versus-Host Disease (cGVHD) is a complication of hematopoietic cell transplantation (HCT). While the clinical outcomes of cGVHD are well documented, few studies have assessed its treatment practices in the real-world. The objectives of this study are to quantify the prevalence of cGVHD, to examine provider prescribing patterns, and to evaluate the healthcare cost and resource utilization (HCRU) in a real-world US cGVHD population. Authors Carlos Bachier, Sanjay Aggarwal, Kalin Hennegan, Andrew Milgroom, Kevin Francis, Marcello Rotta Journal Blood; American…

Healthcare Utilization Patterns Among Commercially Insured Patients with Prader-Willi Syndrome: A Retrospective Analysis of Administrative Claims

Prader-Willi syndrome (PWS) is a complex orphan endocrine disease characterized by hyperphagia and abnormal food-related behaviors that contribute to severe morbidity and early mortality along with a significant burden on patients and caregivers. Life-long medical care is required but the consistency of services rendered to this population has not been evaluated. This study characterized use of US hospital care, specialty physician care, and growth hormone (GH) therapy for PWS patients at different life stages. Authors Merlin Butler, Ann Manzardo, Theresa…

U.S. Prevalence & Mortality of Prader-Willi Syndrome: A Population-Based Study of Medical Claims

Prader-Willi syndrome (PWS) is a complex developmental genetic disorder associated with hypotonia, poor feeding in neonates, onset of hyperphagia in early childhood, and shorter overall life expectancy. Prior epidemiology studies of PWS have examined smaller populations, with limited research in a US population. The aim of this study was to provide a contemporary estimate of PWS prevalence and annual all-cause mortality in the US using a large administrative medical claims dataset. Authors Shawn McCandless, Marissa Suh, David Yin, Michael Yeh,…

Comparative Comorbidity Burden Among Patients with Prader-Willi Syndrome: A Population-Level Cohort Survey

Prader-Willi syndrome (PWS) is a rare, complex multi-system genetic disorder characterized by hyperphagia and abnormal food-related behaviors that contribute to severe morbidity and early mortality and to a significant burden on patients and caregivers. The hyperphagia seen in people with PWS can result in significant obesity. This study assessed rates of comorbidities associated with obesity, including type II diabetes (T2D), cardiovascular disease (CVD), and sleep apnea (SA) in a large US PWS vs. a non-PWS cohort. Authors Diane Stafford, Justin…
