Overview
History, complication of delirium and prognosis depends for many factors such as, etiology, risk factors, and co-morbid illness.
History
- The duration of delirium is typically affected by the underlying cause.
- If caused by a fever, the delirious state often subsides as the severity of the fever subsides.
- Ranges from less than a week to more than 2 months.
- Most of the time symptoms resolve by 10 to 12 days.
- Up to 15% of patients, typically elderly, delirium may last for a month and beyond.
- Delirium associated with substance withdrawal develops when concentrations of the substance in fluid and tissue decrease after sustained, high-dose use of certain substances.
Complications and Prognosis
- The duration of delirium may vary from days to months.[1]
- If left untreated, delirium may progress to stupor, coma, seizures, or death.
- Delirium in the elderly, can cause many complications, which may include pneumonia and decubitus ulcers, prolonging hospital stays.
- Only 4% to 40% may have a complete recovery.
- Persistent cognitive deficits are common while recovering from delirium, may be related to previously unknown ailments.
- 22%–76% chance of dying during hospitalization if delirium is developed during the respective hospital stay and a very high death rate during the months following discharge.
- Up to 25% of patients with delirium die within 6 months and that their mortality rate in the 3 months after diagnosis is 14 times as high as the mortality rate for patients with affective disorders.
- Delirium was associated with longer postoperative recovery periods, longer hospital stays, and long-term disability after orthopedic surgery.[2]
- Common complications associated with delirium include increased mortality, cognitive impairment, longer durations of mechanical ventilation, longer lengths of stay in the ICU.[3]
- Prognosis is dependent on the severity of delirium, and the 1 year mortality rate of patients with delirium is approximately 10%-26%.[4]
