- W2766101285 abstract "It is expected that increased utilization and costs will be observed leading up to and after incident Alzheimer's disease (AD) diagnoses, especially when compared to a non-AD patient population. Medical and pharmacy claims from a database of Medicare Supplemental insurance for the period 2001–2013, was used to identify cases of newly diagnosed AD. Cases were identified as beneficiaries aged ≥65 with medical and prescription drug coverage, a claims history of AD diagnosis and prescription for a medication indicated to treat AD. Mean health care utilization and total health plan costs were estimated in the two years prior to and after incident (i.e. index) AD diagnosis. A control cohort of elderly individuals without any dementia type or AD treatment was constructed for descriptive comparison with index dates defined arbitrarily around a similar time window as the AD cohort. A cohort of 67,713 beneficiaries diagnosed with AD was identified for inclusion in the analysis along with a control cohort of 3,044,429 beneficiaries without AD. Inpatient and outpatient costs constituted 25% and 40%, respectively, of the total per-patient cost for the two years prior to and after the index period. Medication accounted for 31% of all costs, and ER visits approximately 4%. Compared to the pre-index period, post-index total costs increased by 22%; varying between 16% increase in inpatient costs to 39% increase in ER visit cost for cases. Compared to the non-AD cohort, AD patient costs were about 50% higher in both pre and post index periods Costs were higher for all categories for the AD group with the highest difference observed for ER visits (between two to three-fold higher in the AD cohort in both periods). Health care costs increased after the incident diagnosis for the AD cohort, and were consistently higher across all cost categories compared to non-AD controls. ER visits, although smaller in magnitude had the highest difference between AD and control cohorts." @default.
