Potentially inappropriate prescribing is common in older people presenting to hospital with acute illness in Ireland. The aim of this study was to determine if this phenomenon is unique to Ireland or whether it is a more widespread problem in hospitals across Europe. Prospective data were collected from 900 consecutive older patients admitted to six(More)
Frailty has long been considered synonymous with disability and comorbidity, to be highly prevalent in old age and to confer a high risk for falls, hospitalization and mortality. However, it is becoming recognized that frailty may be a distinct clinical syndrome with a biological basis. The frailty process appears to be a transitional state in the dynamic(More)
OBJECTIVES To identify early markers of prolonged hospital stays in older people in acute hospitals. DESIGN A prospective, multicenter study. SETTING Nine hospitals in France. PARTICIPANTS One thousand three hundred six patients aged 75 and older were hospitalized through an emergency department (Sujet Agé Fragile: Evaluation et suivi (SAFEs)--Frail(More)
To identify predictive factors for 2-year mortality in frail elderly patients after acute hospitalisation, and from these to derive and validate a Mortality Risk Index (MRI). A prospective cohort of elderly patients was set up in nine teaching hospitals. This cohort was randomly split up into a derivation cohort (DC) of 870 subjects and a validation cohort(More)
Geriatric pharmacotherapy represents one of the biggest achievements of modern medical interventions.

BACKGROUND In France, there is evidence to suggest that 50% of elderly individuals are prescribed psychotropic medications. However, it is known that use of these agents increases the risk of falls, fractures and delirium in older people.
