“预防为主”的方针,是整个卫生、医疗、疗养、康复活动都要贯彻的方针,所以预防医学才有三级预防的概念。一级预防是防病于未然,除了提高文化卫生知识水平,还有为了增进健康可以采取的一切措施,也包括预防注射这种特殊防护手段。二级预防是早期发现和及时地、正确地合理治疗,在二级预防的治疗中已包括心理治疗。二级治疗的目的是争取病人早愈,防止转成慢性,对传染病特别要防止变成慢性带菌(虫、病毒)者。三级预防主要目的是防止伤残,争取更好、更快的全面康复(功能的、心理的、局部组织的等)。在二级、三级预防中都包括心理的、情绪的治疗,国内探讨的音乐治疗,其实质也是心理,情绪的一种改善,这里介绍的就是三级预防国外的一种社会实践。 The principle of “prevention first” is the policy that must be followed throughout health, medical care, convalescence, and rehabilitation activities. Therefore, preventive medicine has the concept of three levels of prevention. Primary prevention is the prevention of disease. In addition to raising the level of knowledge in culture and hygiene, there are all measures that can be taken to promote health, including special prevention measures such as injection prevention. Secondary prevention is early detection and reasonable treatment in a timely and correct manner. Psychotherapy has been included in the treatment of secondary prevention. The purpose of secondary treatment is to strive for early recovery of the patient and prevent it from becoming chronic. Infectious diseases are particularly prevented from becoming chronic carriers (insects, viruses). The main purpose of tertiary prevention is to prevent disability and to strive for better and faster comprehensive rehabilitation (functional, psychological, local, etc.). In both secondary and tertiary prevention, psychological and emotional treatment is included. The music treatment discussed in the country is also a psychological and emotional improvement. Here is a third-level prevention of foreign social practice.
