PURPOSE The purpose of this study was to identify reliable predictors of nursing home entry over a 3-year period in a sample of 3,944 persons with dementia who resided in a home setting at baseline. Strengths of the analysis include a multiregional recruitment strategy, incorporation of salient caregiver characteristics, and a 3-year prospective design that(More)
BACKGROUND Federal and state agencies are considering ICU performance assessment and public reporting; however, an accurate method for measuring performance must be selected. In this study, we determine whether a substantial variation in ICU mortality performance still exists in modern ICUs, and compare the predictive accuracy, reliability, and data burden(More)
BACKGROUND To develop and compare ICU length-of-stay (LOS) risk-adjustment models using three commonly used mortality or LOS prediction models. METHODS Between 2001 and 2004, we performed a retrospective, observational study of 11,295 ICU patients from 35 hospitals in the California Intensive Care Outcomes Project. We compared the accuracy of the(More)
BACKGROUND Medicare claims as the basis for health condition adjustments is becoming a method of choice in capitation reimbursement. A recent study has found that claims-based beneficiary classification for Alzheimer's disease produces lower prevalence estimates and higher average costs than previous healthcare cost studies in this population. These sets of(More)
PURPOSE Our objective in this analysis was to determine how the duration of caregiving interacts with key care demands (i.e., severity of problem behaviors) to influence the institutionalization of individuals suffering from dementia. METHODS We utilized multiregional data from 4,761 caregivers of individuals with dementia over a 3-year period. We(More)
OBJECTIVES We develop and test a model of 12-month mortality among persons (N=3858) with organic dementia. METHODS Data are from caregiver interviews and claims records for persons enrolled in the Medicare Alzheimer's Disease Demonstration Evaluation. Information covers the year prior to enrollment through 36 months. We used Proportional hazards models to(More)
The objective of the present study was to identify predictors of institutionalization in African Americans who suffer from dementia. Data were derived from the Medicare Alzheimer's Disease Demonstration Evaluation (MADDE), which collected information on Alzheimer's patients and their family caregivers over a 3-year period. The baseline MADDE sample included(More)
CONTEXT Current intensive care unit performance measures include in-hospital mortality after intensive care unit admission. This measure does not account for deaths occurring after transfer to another hospital or soon after discharge and therefore, may be biased. OBJECTIVE Determine how transfer rates to other acute care hospitals and early post-discharge(More)
Applicants were randomized either into a group with a limited Medicare community care service benefit and case management or into a control group receiving their regular medical care. Analyses assess whether or not community care management affected health care use. A tendency toward reduced expenditures was observed for the treatment group, combining all(More)
