Purpose: The goal of this study was to estimate the economic burden (EB) of smoking related premature death using willingness to pay (WTP) on quality-adjusted life years (QALYs) loss.
Methods: Total 35 smoking related diseases were obtained from a recent Korean economic burden of study. The population attributable fraction (PAF) of smoking for each disease was calculated using relative risk of each disease and smoking prevalence. After estimating QALY loss for premature death on each disease, we applied WTP to estimate the EB of diseases. Finally, the EB of smoking related premature death was estimated by applying the PAF.
Results: Total QALY loss of 35 smoking related premature death in 2013 was 137,799 QALYs. Among the assessed 35 diseases, the largest QALY loss was for bronchial and lung cancer (48,725 QALYs), followed by ischemic heart disease (13,212 QALYs), and stomach cancer (7,224 QALYs). Total cost due to smoking related premature death was 4,243 billion KRW. When estimating the cost by disease, the highest cost also was for bronchial and lung cancer (1,486 billion KRW), followed by ischemic heart disease (403 billion KRW), and stomach cancer (220 billion KRW).
Conclusions: The EB of smoking related premature death is substantial in Korea. It seems necessary to consider QALYs and WTP when estimating EB of premature death.
