Admission to hospital is decided by the Director on the advice of a doctor or intern in the establishment. Except in emergencies recognised by the establishment’s doctor or intern on duty, it is decided upon on presentation of a certificate from a doctor in attendance or belonging to the establishment’s consultation service attesting to the need for hospital treatment. This certificate may indicate the discipline to which the person concerned should be admitted, without mentioning the diagnosis of the condition giving rise to the admission. It is accompanied by a sealed letter from the attending physician or the consulting physician addressed to the physician of the hospital department giving all medical information useful to the latter for diagnosis and treatment.
