医疗卫生服务是十分昂贵的,世界上还没有一个国家有充足的人力、物力和财力可以满足本国居民的卫生保健需求。的确还存在着很多要求改善健康状况的问题。因此,应当对于不同的人群(如孕妇和老年人或慢性病人)的卫生需求加以对比,往往他们的需求不会是一样的。可是,目前常常单纯凭主观的判断来决定卫生资源的分配,例如,在许多国家中习惯上给予慢性精神病人 Medical and health services are very expensive. No country in the world has sufficient human, material and financial resources to meet the health care needs of its residents. There are indeed many problems that require improving health. Therefore, the health needs of different groups (such as pregnant women and the elderly or chronic patients) should be compared, and their needs will not be the same. However, the current allocation of health resources is often based on subjective judgments. For example, chronic mental patients are habitually given in many countries.
