美国9人中大约有1名老年人。1978年,65岁以上老人占总人口11％,但是这部分人的就诊数占总就诊数16％(1980年),住院—24％,短期留医院住院天数的36％,而且在长期医护机构住院治疗的病人中86％是老人(1981年)。1978年美国用于个人卫生保健的支出中,有29％(3,767,400万美元)是花在65岁以上老人的保健上,其中2/3是为支付在医院和长期医护机构的医护费用。除牙科治疗外,年纪稍大的人无论是看病,或住院及长期医护都比年轻一些的人多。造成这种结果的原因,除年龄因素外,还因为老年人患慢性疾
There are approximately one elderly person out of 9 in the United States. In 1978, the elderly aged over 65 accounted for 11% of the total population. However, the number of patients in this group accounted for 16% of the total number of visits (1980), hospitalization - 24%, and 36% of hospitalization days for short-term hospital stays, and they were in long-term healthcare institutions. 86% of hospitalized patients were elderly (1981). Of the US spending on personal health care in 1978, 29% (US$37,744 million) was spent on health care for people over the age of 65, of which 2/3 were for hospitals and long-term care institutions. In addition to dental treatment, older people are more likely than younger people to see a doctor, or to be hospitalized and have long-term care. The reasons for this result are not only due to age but also because the elderly suffer from chronic diseases.
