The Healthcare Access Service (SAS) of the Emergency Department of the CHG du Havre is a telephone regulation (i.e., orientation) service for users of Le Havre. Access to this service, during a call, gives access to a Medical Regulation Assistant (ARM) (first contact) who determines, in less than 30 seconds, the degree of urgency applicable to the "caller" in order to direct the latter to the "primary care" channel or the "urgent medical assistance" channel. Thus, in the context of a non-life-threatening emergency, this service allows access during the day to a consultation with a healthcare professional. When their primary care physician is not available, the "caller" is directed by a Medical Regulation Assistant (ARM) to an Unscheduled Care Operator (OSNP) who can provide medical advice, offer a teleconsultation, or direct them, depending on the situation, to an unscheduled care consultation in an office, at home, or at a health center. This service therefore allows for patient referrals and gives patients direct access to healthcare professionals known as "performers" of primary care (doctor, midwife, dentist) within very short timeframes (most often during the day, and 48 hours at the latest). This medical regulation is made possible through the use of a shared calendar between independent healthcare professionals and the healthcare access service (SAS). In the event of a life-threatening emergency, the "caller" is directed by the Medical Regulation Assistant (ARM) to an emergency Medical Regulation Assistant (ARM) who assesses the actual degree of urgency, the medical needs and the possibility of triggering the SAMU intervention. Before its implementation, the patient journey was complicated by the lack of a link between regulation and so-called "field" medical professionals, now called "performers" of primary care. Indeed, the initial so-called "standard" regulation system did not have a "primary care" referral system (with very rapid appointments to primary care for semi-emergencies (unscheduled community care)), potentially saving recourse to emergency services or medical time in situations not requiring medical advice (request for contact details of on-call pharmacy).
