The objectives of this cross-sectional analysis were to determine healthcare resource utilization and cost for community-dwelling patients with dementia (PWD) from a payer's and societal perspective, and to analyze the associations between costs and sociodemographic and clinical variables. Analysis of healthcare costs from a payer's perspective was based on a sample of 425 PWD, analysis of healthcare costs from societal perspective on a subsample of 254 PWD and their informal caregivers. Frequency of healthcare resource utilization was assessed by means of questionnaires.
