With the help of medical progress, life expectancy has increased in our country, resulting in an increase in the number of elderly people and especially so-called complex patients. These complex elderly patients present with a combination of poly pathology, locomotor disorders and loss of autonomy, which leads to increased risks of hospitalization, re-hospitalization or difficulty in remaining at home. These risks could be reduced by early adapted care specific to this type of patient. To do this, it is necessary to identify these complex elderly patients as early as possible in their care pathway.

Screening complex elderly patients in the emergency department would require trained and educated staff, or the use of a simple, rapid and reliable diagnostic scale. The purpose of this study is to compare two scales for the screening of complex elderly patients, whose use is adapted to the Hospital Emergency Department environment.

This study assess the diagnostic performance of the ISAR and SoCoLoc scales for complex elderly patients.

The assumption of the study is that at least one of these two scales (ISAR or SoCoLoc) is adapted to the constraints of hospital emergencies and that it presents good performances for the screening of elderly patients in complex medico-social situations (sensitivity ≥ 90% and specificity ≥ 50%).

Inclusion Criteria:

• Patients over 75 years of age
• Patient presenting to the "Emergency Department" of the Annecy Genevois hospital, whatever the reason for consultation, from Monday to Friday between 8:00 a.m. and 8:00 p.m.
• Patient informed of the study and not opposed to participation

Exclusion Criteria:

• Patients under guardianship or curatorship
• Patients under the safeguard of justice
• Patient presenting for a life-threatening emergency
• Patient unable to answer the questions on the scales
• Patient does not speak French
• Patients who have already been included in the study: any patient already included in the study and making another trip to the emergency department cannot be included a second time.

The study will focus on patients aged 75 and over who consult the Emergency Department of the Annecy Geneva Hospital.
