Iatrogenesis, frailty, and geriatric syndromes.

Older adults are at risk for iatrogenesis, especially if they are frail and have 1 or more geriatric syndromes. Iatrogenic events do not occur only in acute care; in nursing homes they affect 65% of residents annually. It is therefore likely that they are occurring in assisted living communities, though perhaps called by another name. Most commonly, iatrogenesis is an adverse drug event or reaction. Knowing more about the characteristics of frailty and the contributing factors to geriatric syndrome(s), assisted living nurses can be better prepared to monitor, detect, describe, and communicate an iatrogenic event or outcome. This article describes the signs and symptoms of atypical presentation of illness that can mask or are associated with iatrogenesis. Evidence-based assessment instruments are suggested for each geriatric syndrome.
