Stroke leaves serious neurological sequelae, which require long-term medical and social care, imposing financial and mental burdens on the patients and their families, and causing enormous losses to society. It is currently required that medical resources be used efficiently and the cost-effectiveness of treatment be analyzed carefully. We conducted a follow-up survey of stroke patients admitted to the hospital attached to our university in order to build a picture of the current status of chronic-phase stroke medical treatment. In total, 330 patients were analyzed in this study. We evaluated utility and medical cost at one year after onset. To investigate the relationship between activities of daily living (ADL) classified according to the modified Rankin scale (mRS) and quality of life (QOL), utility was calculated for each ADL level. Utility at 1 year post-onset for each mRS level was: ADL0, 0.89; ADL1, 0.79; ADL2, 0.65; ADL3, 0.58; ADL4, 0.36; and ADL5, 0.09. A significant correlation was seen between utility and mRS. Direct monthly medical costs at 1 year post-onset were 61,536 yen in the ADL0 group and 383,444 yen in the ADL5 group, indicating that a worse ADL score required higher medical costs. Direct monthly costs were significantly different between ADL levels. This present study has clarified the QOL and medical costs of chronic-phase stroke patients, and many cost-utility analyses will be based on our data in the future in Japan.
