For almost 17 % of cases patients over 75 years are sent for inappropriate reasons to the emergency unit. They are described as inappropriate hospitalization because they don't require the use of technical platform or diagnostic neither therapeutic procedures under medical supervision. Those are inappropriate because the patient could have a paramedical and social care at home or in more efficient structures. The hospital remains the place of remedy for social and health situations whose resolution was not possible because of a lack of infrastructure available, of patient or his relative information, or a lack of coordination in medico-social establishment.
