Regular review: Delirium: optimising management
Аннотация: Delirium is a complex neuropsychiatric syndrome with an acute onset and fluctuating course; it is common in all medical settings. Delirium occurs in about 15-20% of all general admissions to hospital1; it occurs with higher frequency in elderly people and in those with pre-existing cognitive impairment.2 Delirium has many synonyms, reflecting its ubiquitous nature rather than distinct conditions. These synonyms include acute brain failure, acute confusional state, and post-operative psychosis. Delirium has not been well studied owing to methodological difficulties and a lack of consensus about its definition. Thus, delirium has been underappreciated as an independent entity that requires therapeutic intervention beyond identification of the syndrome and amelioration of the underlying cause. The development of a clearer definition, improved detection and assessment tools, and recognition of the significant independent morbidity associated with delirium have substantially changed this situation. These developments coupled with a greater awareness of the needs of an increasingly large population of elderly people3 make a review of the day to day management of patients with delirium timely.
#### Summary points
Delirium is especially common in elderly patients and poses a substantial challenge for clinicians
Delirium comprises a wide of range of symptoms, but the prevailing narrow definition impedes diagnosis and efforts to improve treatment
Diagnosis can be improved by clinicians becoming more aware of hypoactive presentations, incorporating cognitive assessment into routine practice, and using simple screening instruments
Environmental strategies for treatment are free of adverse effects but are underutilised
Neuroleptics (such as haloperidol) continue to be used as first line treatment, but benzodiazepines are indicated in specific situations
This review is based on the results of a Medline search for articles published between 1980 and 1999 using the key words “delirium,” “acute confusion,” “management,” and “treatment”; as well as hand searching for articles in major journals …
