Objectives:
Stroke case fatality is decreasing over time. Less, however, is known about patients' health-related quality of life (HRQoL), quality-adjusted life years (QALYs), and costs. We studied all these with two data sets collected in Finland 10 years apart.
Methods:
A total of 468 and 355 first-ever ischemic stroke patients were followed up 1 year in two studies (Study 1 in 1989-1991 and Study 2 in 2001-2003). Case fatality, HRQoL measured by the 15D, QALYs, costs, and first-year cost/QALY were compared. Regression analysis was used to examine the effects of various factors on QALYs.
Results:
In the later study, the case fatality rates were lower and the mean 15D scores higher. During the follow-up year, patients experienced on average 0.519 (95% CI 0.453-0.555) and 0.646 (95% CI 0.613-0.680) QALYs in Study 1 and Study 2, respectively (P < 0.001). Age, modified Rankin Scale before stroke onset, acute phase Scandinavian Stroke Scale, and the study group explained the variance of QALYs. The first-year mean total costs were 10 626 € and 14 603 € and the mean cost/QALY 20 474 € and 22 605 € in Study 1 and Study 2, respectively. The incremental cost-effectiveness ratio of Study 2 compared with Study 1 was 31 315 € without and 60 684 € with patient characteristics standardization.
Conclusions:
Stroke patients' improved outcome is clear, but it remains uncertain to what extent it is attributable to the development of care. More research is needed to study the cost-effectiveness of stroke care.
