Patterns of dementia treatment and frank prescribing errors in older adults with Parkinson disease.

This analysis of Medicare claims data found a significant prevalence of concurrent use of dementia medication with acetylcholinesterase inhibitors and anticholinergic medications. This medication combination is a frank medical error that the authors describe as a never event. Despite this, coprescription occurred in 44% of those prescribed dementia medication, and this medication error was more common in the southeastern and midwestern regions of the United States compared to the northeast or western regions.
