Assessing quality of life of patients with stroke using EQ-5D and SF-12

To compare.the results of EQ-SD and SF-12 for assessing health-related quality of life in stroke patients. EQ-5D and SF-12 were administered to 598 ischemic stroke patients through face-to-face interviews. Differences in PCS-12 and MCS-12 scores across different levels of EQ-5D dimensions were tested using analysis of variance (ANOVA). The EQ-5D index and visual analogue scale/score (VAS) scores of respondents were compared between those with higher than and lower than median SF-12 scores using student t-test. Pearson correlations between PCS-12 and EQ-5D scores were tested. PCS-12 and MCA-12 scores varied across different levels of EQ-5D dimensional scores, except for pain/discomfort. EQ-5D and VAS scores varied between those with high and low SF-12 scores. No significant differences in EQ-5D index and VAS scores were found in the EQ-5D indicated healthy respondents between those with high and low SF-12 scores (P>0.05). PCS-12 was positively correlated with EQ-5D index and VAS scores, with r=0.15 (P
