Low mobility and bedrest are common in hospitalized older patients and are important predictors of adverse outcomes. This study demonstrated that the adverse outcomes associated with low mobility and bedrest may be viewed as iatrogenic events leading to complications, such as functional decline.

The health care costs of falls are pervasive and substantial, and they increase with fall frequency and severity.

Our study documents no difference in outcomes from ICU care in older patients with and without dementia. There was no increased short-term mortality rate in older patients with dementia compared with those without dementia after admission to the ICU. Presumptions that outcomes from critical care are less favorable in patients with dementia should not drive treatment decisions in the ICU.
