Investments in medical research can result in health improvements, reductions in health expenditures and secondary economic benefits. These "returns" have not been quantified in Canada. Our objective was to estimate the return on cardiovascular disease research funded by public or charitable organizations.
Our primary outcome was the internal rate of return on cardiovascular disease research funded by public or charitable sources. The internal rate of return is the annual monetary benefit to the economy for each dollar invested in cardiovascular disease research. Calculation of the internal rate of return involved the following: measuring expenditures on cardiovascular disease research, estimating the health gains accrued from new treatments for cardiovascular disease, determining the proportion of health gains attributable to cardiovascular disease research and the time lag between research expenditures and health gains, and estimating the spillovers from public- or charitable-sector investments to other sectors of the economy.
Expenditures by public or charitable organizations on cardiovascular disease research from 1981 to 1992 amounted to $392 million (2005 dollars). Health gains associated with new treatments from 1994 to 2005 (13-yr lag) amounted to 2.2 million quality-adjusted life-years. We calculated an internal rate of return of 20.6%.
Canadians obtain relatively high health and economic gains from investments in cardiovascular disease research. Every $1 invested in cardiovascular disease research by public or charitable sources yields a stream of benefits of roughly $0.21 to the Canadian economy per year, in perpetuity.
对医学研究的投资可带来健康改善、医疗支出减少及次级经济效益。在加拿大,这些“回报”尚未得到量化。我们的目标是估算由公共或慈善组织资助的心血管疾病研究的回报率。
我们的主要结果是公共或慈善资金资助的心血管疾病研究的内部收益率。内部收益率是指对心血管疾病研究每投入1美元每年给经济带来的货币收益。内部收益率的计算涉及以下方面:衡量心血管疾病研究的支出,估算心血管疾病新疗法带来的健康收益,确定可归因于心血管疾病研究的健康收益比例以及研究支出与健康收益之间的时间间隔,估算公共或慈善部门投资对经济其他部门的溢出效应。
1981年至1992年公共或慈善组织在心血管疾病研究上的支出达3.92亿美元(按2005年美元计算)。1994年至2005年(滞后13年)与新疗法相关的健康收益达220万个质量调整生命年。我们计算出内部收益率为20.6%。
加拿大人在心血管疾病研究投资中获得了相对较高的健康和经济收益。公共或慈善资金每投入1美元用于心血管疾病研究,每年可为加拿大经济带来约0.21美元的持续收益。
