Delirium in elderly patients
Cole MG.. The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry, 2004-01-01
Topic: Risk, prevention and care in population studies
Delirium is a mental disorder characterized by disturbances in consciousness, orientation, memory, thought, perception, and behavior, of acute onset and fluctuating course. It occurs in hyperactive, hypoactive, or mixed forms, in up to 50% of elderly hospital inpatients, many with pre-existing dementia, and appears to be independently associated with significant increases in functional disability, length of hospital stay, rates of admission to long-term care institutions, rates of death, and healthcare costs. Despite its clinical importance, delirium is often not detected or it is misdiagnosed as dementia or other psychiatric illness even though there are potential strategies (e.g., screening by nurses, risk-factor assessment) and instruments that can improve detection and diagnosis. Although there has been limited progress in understanding the etiology, pathogenesis, assessment, and specific treatment of delirium, systematic detection and treatment programs appear to be beneficial for elderly surgical patients, as are preventive programs for elderly medical and surgical patients. Even now, there is probably enough evidence to recommend implementation of these two types of programs in acute-care hospitals.
Key findings
- It occurs in hyperactive, hypoactive, or mixed forms, in up to 50% of elderly hospital inpatients, many with pre-existing dementia, and appears to be independently associated with significant increases in functional disability, length of hospital stay, rates of admission to long-term care institutions, rates of death, and healthcare costs.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
