Many of the 1.6 million nursing home residents with dementia have multiple illnesses and take many potentially interacting medications.
In a new study, researchers found nursing home residents with dementia who are being treated with warfarin to prevent blood clots due to other conditions are at higher risk of adverse warfarin events (AWEs) than are residents without dementia.
After adjusting for resident and facility characteristics, the researchers found residents with dementia had a significant 36% higher risk of a preventable or potential AWE than residents without dementia. Having more than the all-facility median for RN or LPN time available per resident reduced the risk of a preventable or potential AWE by a significant 34%.
