ABSTRACT
BACKGROUND:
The absolute burden of stroke in Korea is ever growing. Many studies have explored the outcomes of mortality, quality of life (QOL), and/or economic burden with limited periods of observation. Relatively few have addressed the lifetime outcomes that are estimated beyond the limited observation period of study samples.AIMS:
By combining QOL and the survival functions over a lifetime horizon, our aims were to estimate the quality-adjusted life expectancy (QALE) and loss-of-QALE of patients with ischemic and hemorrhagic stroke in South Korea, and to compare them between genders.METHODS:
The survival function of stroke patients (n = 13,994) was estimated by the Kaplan-Meier's method from the National Health Insurance Service-National Sample Cohort of Korea (2002-2015), and then extrapolated to lifetime through a rolling-over algorithm. The QOL measurements, assessed by EuroQol 5-dimension (EQ-5D) questionnaire, of stroke patients (n = 474) were extracted from the Korea Health Panel (KHP, 2008-2018) to estimate the QALE. All stroke patients were categorized by sex and two types of stroke ischemic and hemorrhagic. Age-, sex-, and calendar year-matched referents were simulated from the Korean life tables to be integrated with the general population's QOL from the KHP to estimate the QALE of the referents. We calculated the loss-of-QALE by comparing the above two sets of QALE.RESULTS:
The QALE and loss-of-QALE for ischemic stroke were 10.8 and 6.1 QALYs (quality-adjusted life years), respectively, and 14.0 and 9.0 QALYs for hemorrhagic stroke. The loss-of-QALE in men was 3.0 QALYs larger than that of women with hemorrhagic stroke (p < 0.05), while the difference for ischemic stroke was much smaller and statistically insignificant at 0.6 QALYs.CONCLUSIONS:
The lifetime impact of stroke in Korea is large, especially for males who survived hemorrhagic stroke. Future studies assessing the lifetime needs for long-term care of stroke patients are warranted to quantify the burden of stroke from the societal perspective.Palavras-chave
