Since 80's, admissions in Emergency medical services increase regularly. Children represents 30% of the patients in Emergency medical Service. Only 20% of admissions are hospitalized and only 3 % need emergency care. Consequences are team's exhaustion, a reduction of healthcare quality, a slowdown in emergency care.

Investigator decided to realize an epidemiologic prospective study in Emergency medical and surgical Pediatric Service in Strasbourg Teaching Hospital to compare coverage of children who are referred by a liberal doctor with children who are coming by themselves matched with age and complaint.

This study will analyze the relevance of complaints and decision-making factors for the liberal doctor to send children in Emergency Medical and Surgical Service. Investigator will talk about the importance of close collaboration between liberal doctor and hospital doctor, as well as patient's information about basic care service on nights and week-ends in order to decrease the number of emergency admission.
