Abstract

|
The aims of this study are to conduct meta-analysis for obtaining pooled estimates of the utility weight for stroke and to explore the study design characteristics that determine the utility weight for stroke. Medline (Pubmed), CEA Registry (Tufts Medical Center), and KERIS (Korea Education & Research Information Service) were searched to find out the literature that reported quality of life with stroke. Patient characteristics, utility weights and standard errors were extracted and stratified by severity, study method, respondent and country. All estimates were measured on a 0 to 1 scale with 0 representing the death and 1 representing the perfect health. The pooled estimates of the utility weight were 0.627 for total stroke, 0.756 for mild stroke, 0.631 for moderate stroke, and 0.389 for severe stroke (p=0.0001). Non-patients showed significantly lower utility weights than patients for severe ((p=0.0122) stroke.
