本文从“医疗”和“卫生保健”两个术语的区别着手，分析了当前美国医疗系统负担加重约原因，并探讨了制定全民性卫生政策的必要性，以力求政府从人力和财力上着重于社会性弊病的预防，真正提高全民的健康水平。 This article starts with the distinction between the terms “medical care” and “health care”, analyzes the current reasons why the US medical system’s burden is getting worse, and discusses the necessity of formulating a national health policy, in an effort to focus the government’s efforts on human and financial resources. The prevention of social ills really improves the health of the entire population.
