The prevalence of mental health problems among older adults admitted as an emergency to a general hospital

Abstract

Background: a high prevalence of co-morbid mental health problems is reported among older adults admitted to general hospitals.Setting: an 1,800 bed teaching hospital.Design: consecutive general medical and trauma orthopaedic admissions aged 70 or older were screened for mental health problems. Those screening positive were invited to undergo further assessment, and were interviewed to complete a battery of health status measurements.Results: of 1,004 patients screened, 36% had no mental health problems or had anxiety alone. Of those screening positive 250 took part in the full study. Adjusting for the two-stage sampling design, 50% of admitted patients over 70 were cognitively impaired, 27% had delirium and 8–32% were depressed. Six percent had hallucinations, 8% delusions, 21% apathy and 9% agitation/aggression (of at least moderate severity). Of those with mental health problems, 47% were incontinent, 49% needed help with feeding and 44% needed major help to transfer.Interpretation: we confirm the high prevalence of mental health problems among older adults admitted to general hospitals. These patients have high levels of functional dependency, psychological and behavioural problems which have implications for how they are cared for. Services that identify these problems and offer therapeutic intervention should be evaluated.

Association of psychological morbidity with socio-demographic characteristics among elderly: A cross-sectional study from Eastern India

“…Often, the elderly people are not able to cope up with the rapidly changing world. The prevalence of psychological morbidity and even psychiatric diseases are often very high in this age groups [4] compared to others. A large chunk of geriatric population suffers from major depression.…”

Dementia for hospital physicians

“…Overall, 25% of hospital beds accommodate someone with dementia. [4][5][6][7][8] Most are admitted for legitimate medical illness or injury requiring hospital treatment. Indeed, on average, illness severity is greater in people with dementia than without.…”

“…1,5,8 The National Dementia Strategy argues for a substantial effort to diagnose more and to make diagnoses earlier. In future, patients who carry a diagnostic label may only have mild or minimally disabling dementia.…”

“…Physical disability, dependency and mental health symptoms are much more severe in hospital: half need help eating, or transferring from bed to chair, a third are awake at night, 15% have hallucinations or delusions. 8 …”

Making difficult decisions with older patients on medical wards

“…3,4 These (and various other conditions) are often associated with impairment of mental capacity to make decisions ( Box 2 ). Strictly, mental capacity should be assessed for every decision, about every examination, test, care procedure or treatment, but usually this will be informal and implicit, reserving formal assessment for important, or contentious, decisions.…”
