To study the success and cost of modern medicine in industrialized, rich countries from 1980 to 1990.
Cost per capita and per cent of gross domestic product (GDP) spent on health was related to: (i) mortality in six diseases amenable to treatment by modern medicine; (ii) the sum of those six diseases (avoidable disease); (iii) death due to other, unavoidable diseases; (iv) maternal and infant mortality; (v) life expectancy at birth; (vi) renal dialysis and transplantation rates. Efficiency was studied by comparing a country's avoidable mortality rates multiplied by expenses, to the mean for all countries.
During the 10 years, avoidable death rate decreased 38% but unavoidable death rate only 10%. Life expectancy increased 3%. Cost per capita increased 107% but health expenditures, as per cent of GDP only 10%. There was a reasonable correlation between expenses and avoidable mortality but none between expenses and unavoidable death rate. In 1990 avoidable mortality was lowest in Canada, and highest in Japan. Cost was lowest in New Zealand, and highest in the USA. The efficiency index was highest for Australia, and lowest in the USA.
Modern medicine as we have studied it is successful. Avoidable death rate shows a steep uninterrupted decline over the last 50 years while unavoidable death rate shows only small decreases. Cost as per cent of GDP has increased only moderately. There is a correlation between expenses and mortality from avoidable but not from unavoidable diseases, and a large variation in efficiency.
研究1980年至1990年工业化富裕国家现代医学的成效及成本。
人均成本及卫生支出占国内生产总值(GDP)的百分比与以下各项相关:(i)六种可用现代医学治疗疾病的死亡率;(ii)这六种疾病的总和(可避免疾病);(iii)其他不可避免疾病导致的死亡;(iv)孕产妇和婴儿死亡率;(v)出生时预期寿命;(vi)肾透析和移植率。通过比较一个国家可避免死亡率乘以费用与所有国家的平均值来研究效率。
在这10年中,可避免死亡率下降了38%,但不可避免死亡率仅下降了10%。预期寿命增加了3%。人均成本增加了107%,但卫生支出占GDP的比例仅增加了10%。费用与可避免死亡率之间存在合理的相关性,但费用与不可避免死亡率之间没有相关性。1990年,加拿大的可避免死亡率最低,日本最高。成本在新西兰最低,在美国最高。澳大利亚的效率指数最高,美国最低。
我们所研究的现代医学是成功的。可避免死亡率在过去50年中呈急剧且持续下降趋势,而不可避免死亡率仅略有下降。卫生支出占GDP的比例仅适度增加。费用与可避免疾病死亡率之间存在相关性,但与不可避免疾病死亡率之间不存在相关性,且效率存在很大差异。
