Primary health care plays an increasingly important role. Countries which lack quality primary health care will not be able to ensure a universally accessible and financially efficient health system. ...The World Health Organization (WHO) has already laid the groundwork for the development of primary health care with the adoption of the Declaration of Alma-Ata, which is now considered the "gold standard" for societal commitment to the development of this field (WHO & United Nations Children's Fund). However, the development of primary health care must also be accompanied by the concurrent development of the nursing profession, as primary health care is expanded through newly developed programmes in which nurses assume advanced roles. New programmes are also emerging in the field of mental health care, primarily in the development of community-based mental health services. In Slovenian language, the term "skupnostna psihiatricna obravnava" has come to refer to community(-based) mental health care. In the field of nursing, community nursing in mental health care and psychiatry began to emerge in the US, the UK and Italy as early as 1954. At that time, nurses were sent from psychiatric hospitals to monitor patients diagnosed with schizophrenia in their home environment.
