Abstract:
The authors conducted a survey of healthcare utilization in three dementia syndromes to determine whether type of dementia influenced utilization or resulting direct costs. Patients with Alzheimer disease (n=131), dementia with parkinsonism (n=85), and Huntington disease (n=51) were identified from a registry and enrolled. Caregivers completed the mailed survey, and direct costs were estimated. The presence of dementia with parkinsonism resulted in significantly greater utilization of long-term care services and higher total direct costs. In all three groups, long-term care costs accounted for the majority of direct costs. Unique patterns of utilization and costs are seen in specific neurodegenerative dementias.

Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper.
