The ageing of the french population confronts our society with enormous challenges of which the adaptation and the organization of health and psychosocial cares to aged people. The SAFEs cohort analysis has led to better identify older inpatients that presented adverse outcomes during their hospitalization or after their hospital discharge. From the main results, a feature discussion concerning care models adaptation is proposed. This feature discussion highlights: the importance to rehabilitate functional disorders as soon as possible from the admission in the hospital environment; the negative impact playing by a fragmented and sometimes "over"-specialized hospital care system; the importance of the coordination in cares within and between hospital- and community-care models; the necessity for health care professionals to be better trained to geriatric medicine specificities. Therefore, with the double objective of both optimizing the use of the financial resources and to implement adapted and good quality cares, it is necessary to elaborate a real and concrete health policy specifically dedicated to co-morbid and disabled old adults. Such health policy will have to target the care networks as a whole and lead to specific and adequate financing assistances.
