to access all the services of all relevant health professionals throughout the country. Clinical history A patient's clinical history is a medical-legal document that arises from the interactions between health professionals and their clients. From a medical and legal point of view, the clinical history is the only document valid to track this history of interactions. In primary care, where methods of health promotion are important, the clinical history document is sometimes known as a "health history" (historia de salud) or "life history" (historia de vida). Clinical histories in the SNS The Clinical History of the [Spanish] National Health System (Historia Clínica Digital del Sistema Nacional de Salud, HCDSNS) is intended to guarantee citizens and health professionals access to whatever clinical information is relevant for medical care of a particular patient. This history should be available at all authorized locations, but nowhere else: except as needed for treatment, the information is considered confidential and access is restricted. Health Areas The term "Health Area" (Área de Salud) refers to an administrative district that brings together a functional and organizational group of health centers and primary care professionals. A Health Area may be exclusively focused on primary care or may include specialists as well. Some autonomous communities use different term, such as Direction of a sector (Dirección de sector), or of a comarca, district, department, or other territorial unit used in that autonomous community. Basic Health Zones Although the autonomous communities differ among themselves in layering subdivisions of their health areas, all eventually come down to a Health Zone (Zona de Salud) or Basic Health Zone (Zona Básica de Salud) as the unit for a primary health care team. In Andalusia, for example, each existing Basic Health Zone takes care of a population between 5,000 and 20,000 inhabitants. The Basic Health Zone is served by a single general hospital and specialists' center. Primary Care Article 12 of the Law of Cohesion establishes the concept of "primary care," the basic level of patient care that guarantees the comprehensiveness and continuity of care throughout the patient's life, acting as manager and coordinator of cases and regulator of issues. Primary care includes health promotion, health education, prevention of illness, health care, maintenance and recuperation of health, as well as physical rehabilitation and social work. Primary health care includes service provided either on-demand, scheduled, or urgently, both in the clinic as well as in the patient's
