According to surveys, 13% to 20% of the Service Médical d'Urgence (SAMU) centre 15 (French 911) calls concern elderly patients above 75 years of age. For these patients, the clinical pathway should be decided on the basis of the symptomatology described during the call, but also with the gathering of specific data such as medical social and psychological evaluation. These items allow the regulating doctor to assess comorbidity, on-going treatment, psycho-cognitive status, previous hospitalisations, social situation, and patient expectations and needs.
