Appropriate prescribing of medications for older adults has received great attention in the last decade. However, for many frail older adults, accurately taking the appropriately prescribed medications is a challenge. Complex medication regimens with multiple medications and prescribing providers can be unmanageable for a chronically ill older adult, especially one with cognitive impairment. The results of this study support the need for additional assessments of medication regimens to ensure that the older adults are aware of the medication regimen they are prescribed, and have systems in place to support them in managing their medication regimens. The current Medicare home healthcare benefit is episodic and does not address the needs of chronically ill older adults.Understanding that medication reconciliation is an iterative, ongoing process and not a single intervention delivered during or immediately after hospitalization may decrease the number of medication-related adverse events. This will potentially improve health outcomes and provide a cost savings for the healthcare system. The reconciliation process in the acute care setting is well established. But ongoing, community-based medication reconciliation activities, beyond that done in home healthcare admissions, are not an integral part of the care for chronically ill older adults. The results of this study suggest that assessment of an older adult's medication regimen may require multiple assessments over much longer pe
