US clinical practice guidelines for the diagnostic evaluation of cognitive impairment due to Alzheimer's disease (AD) or a related dementia (ADRD) are two decades old. This evidence-based guideline was developed to empower all clinicians to implement a structured approach for evaluating a patient with symptoms that may represent clinical AD/ADRD. An expert workgroup conducted a review of 7374 publications (133 met inclusion criteria) and developed recommendations as steps in an evaluation process.

View Article and Find Full Text PDFImportance: The arrival of new medications for Alzheimer disease (AD) has prompted efforts to measure their value using conventional cost-effectiveness analyses; however, these analyses focus on how much health improvement new medications generate per dollar spent. As AD disproportionately affects older adults, women, racial and ethnic minority individuals, and individuals with lower socioeconomic and educational levels, it is critical to also examine the health equity outcomes of treatment.
Objective: To estimate the health equity impact of a hypothetical disease-modifying treatment for early AD in the US and to examine targeted policies to mitigate health care disparities.
Vitiligo is an autoimmune skin depigmenting disorder that can negatively impact quality of life. A new FDA approved treatment for vitiligo offers considerable promise, and to maximize benefits strategies to implementation should consider disease burden, healthcare access, and healthcare utilization of individuals with vitiligo. Using the All of Us Research Program's large data set, including survey responses, we investigated these outcomes among participants with and without vitiligo.

We analyzed Medicare expenditures for beneficiaries with dementia to identify when during the course of care costs are the highest and whether they differ by race and ethnicity.
Methods: We analyzed data from the 2000-2016 Health and Retirement Study (HRS) linked with corresponding Medicare claims to estimate total Medicare expenditures for four phases: (1) the year before a dementia diagnosis, (2) the first year following a dementia diagnosis, (3) ongoing care for dementia after the first year, and (4) the last year of life.

Introduction: Understanding the prevalence of treatment-eligible Alzheimer's disease (AD) is crucial for policy planning.
Methods: We used a comprehensive literature review and population cascade approach to estimate the number of amyloid-positive, clinically diagnosed patients with mild cognitive impairment (MCI) or mild dementia due to AD in the United States.
Results: An estimated 666,646 individuals were identified as having MCI due to AD (range: 351,926-1,227,776) and 620,850 individuals as having mild dementia due to AD (range: 445,082-820,339).
Background: Older adults with dementia including Alzheimer's disease may have difficulty communicating their treatment preferences and thus may receive intensive end-of-life (EOL) care that confers limited benefits.
Objective: This study compared the use of life-sustaining interventions during the last 90 days of life among Medicare beneficiaries with and without dementia.
Methods: This cohort study utilized population-based national survey data from the 2000-2016 Health and Retirement Study linked with Medicare and Medicaid claims.
Introduction: Ever since the United States Food and Drug Administration (FDA) approved aducanumab and Centers for Medicare & Medicaid Service (CMS) restricted coverage for the drug, a crucial question has been how other payers will behave. This study examined how Medicaid and commercial plans cover aducanumab.
Methods: We created a database of aducanumab coverage policies issued by Medicaid fee-for-service programs (50 states and DC) and 35 of the largest commercial plans (covering ∼ 84% of the commercially insured population).
Critical physical systems with large numbers of molecules can show universal and scaling behaviors. It is of interest to know whether human societies with large numbers of people can show the same behaviors. Here, we use network theory to analyze Chinese history in periods 209 BCE-23 CE and 515-618 CE) related to the Western Han-Xin Dynasty and the late Northern Wei-Sui Dynasty, respectively.

We report on the International PharmacoEconomic Collaboration on Alzheimer's Disease (IPECAD) Modeling Workshop Challenge.
Methods: Two common benchmark scenarios, for the hypothetical treatment of AD mild cognitive impairment (MCI) and mild dementia, were developed jointly by 29 participants.

Methods: We examined cholinesterase inhibitors and memantine initiation, non-adherence, and discontinuation by race and ethnicity, using data from the 2000-2016 Health and Retirement Study linked with Medicare and Medicaid claims.
Results: Among newly diagnosed ADRD patients (n = 1299), 26% filled an ADRD prescription ≤90 days and 36% ≤365 days after diagnosis.
An increasing proportion of novel drug approvals use accelerated pathways, with notable growth in the US Food and Drug Administration-designated breakthrough pathway in recent years. Breakthrough therapy (BT) designation suggests that these therapies offer substantial potential to improve health outcomes but their value for money is not fully understood, as BTs typically cost more than non-BTs (NBTs). To assess the economic value of BTs and factors associated with their reported value.

Objective: To explore differences in end-of-life utilization of hospice and hospital services among patients with dementia by race and ethnicity.
Design, Setting, And Participants: This cohort study used national survey data from the Health and Retirement Study linked with Medicare and Medicaid claims that reflected a range of socioeconomic, health, and psychosocial characteristics.
Commercial payers that ultimately decide to cover aducanumab or other Alzheimer's disease therapies may require innovative payment tools to minimize their financial risk given the uncertain benefits and high cost of such treatments. Drawing on the published evidence, we propose two different types of payment models applicable to disease-modifying therapies in Alzheimer's disease, and suggest four strategies to overcome challenges in their implementation. Such strategies range from developing best practices for outcome measurement in Alzheimer's disease, investing in infrastructure to collect real-world data, increasing representativeness of registry data in Alzheimer's disease, and integrating the diagnostic, treatment, and payment landscape.

Background: Herd immunity (HI) is a key benefit of vaccination programs, but the effects are not routinely included in cost-effectiveness analyses (CEAs).
Objective: This study investigated how the inclusion of HI in CEAs may influence the reported value of immunizations in low- and middle-income countries (LMICs) and illustrated the implications for COVID-19 immunization.
Methods: We reviewed immunization CEAs published from 2000 to 2018 focusing on LMICs using data from the Tufts Medical Center CEA Registries.
The pipeline for new treatments for Alzheimer's disease (AD) in the USA contains over 100 different agents, 80% of which can be categorized as disease-modifying therapies. The regulatory approval of the disease-modifying agent aducanumab has brought more attention to the complexity of the diagnosis, evaluation, and treatment of AD and the difficult decisions payers and policy makers will face over the next few years as innovation continues in this space. The value of AD treatment can vary widely according to the perspective of the analysis, sources of data, and methodological approach for the value assessment.
