Released June 12, 2016

Don’t assume a diagnosis of dementia in an older adult who presents with an altered mental status and/or symptoms of confusion without assessing for delirium or delirium superimposed on dementia using a brief, sensitive, validated assessment tool.

Delirium is common in older adults, especially in the hospital setting, yet delirium is frequently unrecognized and not documented by nursing or medical staff. Delirium occurs in as much as 50% of older adults in the hospital and delirium superimposed on dementia occurs in as high as 90%
of hospitalized older adults. Delirium is associated with very poor clinical outcomes, including prolonged length of stay, high costs and lower quality of life for older adults when not detected early. Delirium is treatable and often reversible and dementia is not, so mislabeling older adults with dementia may miss a life threatening underlying condition causing the delirium such as an infection, medication side effect or subdural hematoma. Delirium is extremely costly to the health care system and to society with estimates ranging from $143 to $152 billion annually. Nurses and physicians often fail to recognize delirium. Only 12–35% of delirium cases are detected in routine care, with hypoactive delirium and delirium superimposed on dementia most likely to be missed.

How The List Was Created

The American Academy of Nursing has convened a workgroup of member fellows who are leaders of professional nursing organizations representing a broad range of clinical expertise, practice settings and patient populations. The workgroup collaboratively identifies nursing/interdisciplinary interventions commonly used in clinical practice that do not contribute to improved patient outcomes or provide high value. An extensive literature search and review of practice guidelines is conducted for each new proposed recommendation for the list. The supporting evidence is then reviewed by the respective nursing organization(s) with the most relevant expertise to each recommendation. The Academy workgroup fellows narrow the recommendations through consensus, based on established criteria. The final recommendations are presented to the American Academy of Nursing’s Board of Directors for approval to be added to the Choosing Wisely list created by the Academy.
