  To address the pending public health crisis due to Alzheimer‘s disease (AD) and related neurodegenerative disorders, the Marian S. Ware Alzheimer Program at the University of Pennsylvania held a meeting entitled "State of the Science Conference on the Advancement of Alzheimer's Diagnosis, Treatment and Care," on June 21-22, 2012. The meeting comprised four workgroups focusing on Biomarkers; Clinical Care and Health Services Research; Drug Development; and Health Economics, Policy, and Ethics. The workgroups shared, discussed, and compiled an integrated set of priorities, recommendations, and action plans, which are presented in this article.

  Background Individuals with Alzheimer's disease and related disorders (ADRD) have more frequent hospitalizations than individuals without ADRD, and some of these admissions may be preventable with proactive outpatient care. Methods This study was a cross-sectional analysis of Medicare claims data from 195,024 fee-for-service ADRD beneficiaries aged ≥65 years and an equal number of matched non-ADRD controls drawn from the 5% random sample of Medicare beneficiaries in 2007–2008. We analyzed the proportion of patients with potentially avoidable hospitalizations (PAHs, as defined by the Medicare Ambulatory Care Indicators for the Elderly) and used logistic regression to examine patient characteristics associated with PAHs. We used paired t tests to compare Medicare expenditures by ADRD status, stratified by whether there were PAHs related to a particular condition. Results Compared with matched non-ADRD subjects, Medicare beneficiaries with ADRD were significantly more likely to have PAHs for diabetes short-term complications (OR = 1.43; 95% CI 1.31–1.57), diabetes long-term complications (OR = 1.08; 95% CI = 1.02–1.14), and hypertension (OR = 1.22; 95% CI 1.08–1.38), but less likely to have PAHs for chronic obstructive pulmonary disease (COPD)/asthma (OR = 0.85; 95% CI 0.82–0.87) and heart failure (OR = 0.89; 95% CI 0.86–0.92). Risks of PAHs increased significantly with comorbidity burden. Among beneficiaries with a PAH, total Medicare expenditures were significantly higher for those subjects who also had ADRD. Conclusion Medicare beneficiaries with ADRD were at a higher risk of PAHs for certain uncontrolled comorbidities and incurred higher Medicare expenditures compared with matched controls without dementia. ADRD appears to make the management of some comorbidities more difficult and expensive. Ideally, ADRD programs should involve care management targeting high-risk patients with multiple chronic conditions.

  Individuals with amnestic mild cognitive impairment (MCI) are at elevated risk of developing Alzheimer‘s disease (AD). Although the economic burden of AD itself is well recognized, little is known about the direct and indirect costs associated with MCI before the onset of AD. Insufficient data on the economic impact of MCI as well as other gaps in the knowledge base (such as estimates of MCI progression rates and factors that drive MCI-related costs) present challenges to understanding the burden of MCI and to modeling the cost-effectiveness of potential MCI interventions. Initiating treatment and care management in the MCI phase could improve the health and well-being of patients and caregivers and possibly offset certain costs. Future economic analyses should incorporate new data, as they become available, from patient registries and linked administrative claims and electronic medical records to better characterize the cost consequences of MCI detection and management. Such analyses should help payers, providers, and policy makers make more informed decisions about the costs and benefits of new tests, treatments, and other management strategies for the condition.
