BACKGROUND/AIMS To examine the incremental effect of patients' dependence on others, on cost of medical and nonmedical care, and on informal caregiving hours over time. METHODS Data are obtained from 172 patients from the Predictors Study, a large, multicenter cohort of patients with probable Alzheimer disease (AD) followed annually for 4 years in 3(More)
OBJECTIVES To estimate long-term trajectories of direct cost of caring for patients with Alzheimer disease (AD) and examine the effects of patients' characteristics on cost longitudinally. METHODS The sample is drawn from the Predictors Study, a large, multicenter cohort of patients with probable AD, prospectively followed up annually for up to 7 years in(More)
Most estimates of the cost of informal caregiving in patients with Alzheimer's disease (AD) remain cross-sectional. Longitudinal estimates of informal caregiving hours and costs are less frequent and are from assessments covering only short periods of time. The objectives of this study were to estimate long-term trajectories of the use and cost of informal(More)
BACKGROUND Few studies on cost of caring for patients with Alzheimer disease (AD) have simultaneously considered multiple dimensions of disease costs and detailed clinical characteristics. OBJECTIVE To estimate empirically the incremental effects of patients' clinical characteristics on disease costs. METHODS Data are derived from the baseline visit of(More)
OBJECTIVES The purpose of the study was to examine on a national level the informal costs of caring for elderly community-dwelling male veterans with dementia by female caregivers and the relationships between informal costs and disease severity, and between informal costs and dementia problem behaviors. METHODS Female primary caregivers were drawn from(More)
OBJECTIVE To compare per diem total direct, ancillary (laboratory and radiology) and pharmacy costs of palliative care (PC) compared to usual care (UC) patients during a terminal hospitalization; to examine the association between PC and ICU admission. DESIGN Retrospective, observational cost analysis using a VA (payer) perspective. SETTING Two urban VA(More)
CONTEXT Palliative care consultation teams in hospitals are becoming increasingly more common. Palliative care improves the quality of hospital care for patients with advanced disease. Less is known about its effects on hospital costs. OBJECTIVE To evaluate the relationship between palliative care consultation and hospital costs in patients with advanced(More)
Although nearly one-third of older diabetics are cognitively impaired, their diabetes management remains poorly understood. To examine the relationship between cognitive impairment and diabetes self-management in a population-based community sample of older adults with Type 2 diabetes. Cross-sectional observational analysis. 1,398 persons with diabetes,(More)
OBJECTIVES Treatment with second-generation antipsychotic (SGA) medications has been linked with increased rates of the metabolic syndrome (i.e., dyslipidemia, obesity, and hyperglycemia). Several sets of published recommendations now provide clinicians with guidelines for monitoring metabolic parameters in individuals with schizophrenia treated with SGAs.(More)
Alzheimer's disease is a devastating chronic disease that significantly increases healthcare costs and affects the quality of life (QoL) of the afflicted patients and their caregivers. Population aging and other demographic changes may further increase the already staggering costs of this devastating disease. While few pharmacoeconomic studies have used a(More)
