Background :

The evolving concept of frailty was born in the United States under the term of " frail elderly ". It allows describing geriatrics situations, dominated by the weakness or the functional instability of aged person, illustrating situations at risk. It is about an effective concept, especially in the field of the prevention where it determines strategies of specific care. The ageing, changing according to individuals, is characterized by a decrease of the physiological reserves leading to a precarious balance and to a destabilization.

Epidemiological studies show a very uneven distribution of three categories of old persons according to their health status. Every year, approximately, 12 % of the independent population of 75 years of age and older and living at home, lose their autonomy for one of the activities of the daily life and turn into frailty.

Identifying frailty of old subjects is interesting in order to apply preventive and specific care strategies to reduce the risks of decompensation. The Global Geriatric Assessment (GGA) is the gold standard to detect frailty in this population. The beneficial effects of the GGA during the hospitalization have been recognized in international literature.

The ageing heterogeneousness complexity and the high time-consuming character of GGA led to a difficult approach for the nurses or family practioners in taking care of old persons at home.

To balance these difficulties and to optimize prevention of dependence in the elderly, an experimental unit of prevention was created : Unit for Prevention, Monitoring and Analysis of Aging (UPSAV) on January 4th, 2010 within the geriatric department of the Hospital University of Limoges. It is an innovative organizational structure because, for the first time, the geriatric expertise is proposed freely to the elderly at home. A multidisciplinary gerontological team consisting in a geriatrician, a nurse, a psychomotor therapist and an occupational therapist, can, on requiry, move at old persons' home to make a preventive GGA to detect the risks of loss of autonomy and to propose a coordination of preventive actions.

Purpose :

UPSAV's endpoints are to prevent frail elderly persons from the risk of autonomy loss. This action is led in partnership with all the professionals working around old persons.

The randomized study endpoint is to evaluate elderly from 75 years of age and older at home and to select two homogeneous groups: "reference" and " specific intervention ".

Abstract : The recruitment will be made in the Limousin region within a period of one year by cooptation of families, patients, family practitioners and other partners.

After checking the inclusion criteria and obtaining the signatures of consents, patients will be assessed using the functional status (SMAF) and the Global Geriatric Assessment (GGA).

Patients included in the "specific intervention" group will benefit from a personalized action plan presented in a multidisciplinary staff that will be established according to the detected frailties. In follow up visits, a new evaluation will be done and the action plan reviewed.

Every month, patients of this group will receive a Unit for Prevention, Monitoring and Analysis of Aging (UPSAV) phone call in order to complete the secondary assessment criteria of the trial. Therefore, every patient will be re-evaluated according to the intervention plan of the study.

The quality of life of the patient will be estimated by the scale EQ-5D. In every visit, will be collected in a forward-looking way the medical direct costs (ambulatory, hospital care and medicines) and the non medical costs (transport, helpers, arrangements of the place of residence).

Inclusion Criteria:

• 75 years of age and older man or woman
• Patient covered by the health care system
• Patient coverd by a complementary health system or supported by 100% by the health care system
• Patient having the intellectual skills to understand the study, to respect its imperatives and accept the UPSAV's plan or subject with mild to moderate dementia (MMSE > 10) but with a caregiver at home capable of understanding the protocol and of making respect its imperatives written consent signed by the patient

Exclusion Criteria:

• Nursing-home resident
• Mild to moderate dementia (MMSE > 10) without caregiver
• Severe dementia (MMSE < 10)
• Diseases with vital short-term endpoint
