Abstract:
Purpose and Framework: It is estimated that 4 million people suffer from some form of dementia. Most of these individuals reside in the community and are cared for by family members. Dementia is a costly, highly complex disease process that has wide-ranging medical, psychological, psychiatric, and socio-economic ramifications. The annual per capita expenditures for Medicare beneficiaries with Alzheimer's Disease is $7,682, even though Medicare pays no long-term care. Delirium is often superimposed on dementia, and is associated with decreased ability to function, frequent emergency room visits, prolonged hospitalizations, and an increased likelihood of admission to a nursing home. Several inpatient studies have focused on the recognition and management of hospitalized patients who develop delirium, but few have focused on the cost and prevention of delirium in community living persons with dementia. This study seeks to fill that gap. Specific Aims: This large-scale, on-going descriptive/correlational study is guided by these aims:1) to describe the prevalence of dementia in a managed Medicare and fee for service population; 2) to identify risk factors for delirium in this population; and 3) to identify the resource utilization related to dementia and delirium as compared to a case control population matched by age and co-morbidity. Methods: The study uses a retrospective review of an administrative database for a large HMO located in the Southeast, US. Claims data on demographics, drug use, and healthcare utilization are collected on all individuals with any ICD-9 code for dementia and delirium who were age 45 and above on 1-1-98, and who were enrolled for 12 consecutive months from 1-1-98 to 12-31-2000. Results: We have obtained an " average" membership of 362,975 for those persons 45 years of age and above. Of that number, 11,032 unique individuals were identified with dementia for a prevalence of 3.039%. We will describe the prevalence of delirium in this population, the potentially inappropriate medications prescribed, utilization and cost for this group as compared to case control. Implications: The results of this study will enable HMOs to plan interventions that reduce the incidence of delirium, improve quality of life and reduce cost of care for persons with dementia who live in the community.
