To test the hypothesis that the USA healthcare system was superior to the NHS and 17 other Western countries in reducing feasible mortality rates over the period 1979-2005.
Economic inputs into healthcare, GDP health expenditure (GDPHE) were compared with clinical outputs, i.e. total 'adult' (15-74 years) and 'older' (55-74 years) mortality rates based upon three-year average mortality rates for 1979-81 vs. 2003-2005. A cost-effective ratio was calculated by dividing average GDPHE into reduced mortality rates over the period.
Nineteen Western countries' mortality rates compared between 1979-2005.
Mortality of people by age and gender.
A cost-effective ratio to measure efficiency and effectiveness of healthcare systems in reducing mortality rates. Chi-square tested any differences between the USA, UK and other Western countries.
The USA had the highest current and average GDPHE; the UK was 10th highest but joint 16th overall, still below the Western countries' average. Output: Every country's mortality rate fell substantially; but 15 countries reduced their mortality rates significantly more than the US, while UK 'adult' and 'older' mortality rates fell significantly more than 12 other countries. Cost-effectiveness: The USA GDPHE: mortality rate ratio was 1:205 for 'adults' and 1:515 for 'older' people, 16 Western countries having bigger ratios than the US; the UK had second greatest ratios at 1:593 and 1:1595, respectively. The UK ratios were >20% larger than 14 other countries.
In cost-effective terms, i.e. economic input versus clinical output, the USA healthcare system was one of the least cost-effective in reducing mortality rates whereas the UK was one of the most cost-effective over the period.
检验如下假设,即在1979年至2005年期间,美国医疗体系在降低可避免死亡率方面优于英国国民医疗服务体系(NHS)及其他17个西方国家。
将医疗保健方面的经济投入,即国内生产总值卫生支出(GDPHE),与临床产出进行比较,临床产出即基于1979 - 1981年与2003 - 2005年的三年平均死亡率得出的“成年人”(15 - 74岁)和“老年人”(55 - 74岁)的总死亡率。通过将平均GDPHE除以该时期内降低的死亡率来计算成本效益比。
比较19个西方国家在1979 - 2005年期间的死亡率。
按年龄和性别的人群死亡率。
衡量医疗体系在降低死亡率方面效率和效果的成本效益比。采用卡方检验来检验美国、英国和其他西方国家之间的差异。
美国当前和平均GDPHE最高;英国当前GDPHE排名第10,但总体排名并列第16,仍低于西方国家平均水平。产出:每个国家的死亡率都大幅下降;但15个国家降低死亡率的幅度明显超过美国,而英国“成年人”和“老年人”死亡率下降幅度明显超过其他12个国家。成本效益:美国GDPHE与死亡率的比率,“成年人”为1:205,“老年人”为1:515,16个西方国家的比率高于美国;英国的比率分别为第二高,即1:593和1:1595。英国的比率比其他14个国家高出20%以上。
从成本效益角度来看,即经济投入与临床产出方面,美国医疗体系是降低死亡率方面成本效益最低的体系之一,而在此期间英国是成本效益最高的体系之一。
