“…In addition, we previously reported that no age-related differences in health utility were found between middle-aged and older patients upon entrance into a phase II CR program at 1 month and at 3 months after cardiac surgery [21]. This indicates that aging might not reflect differences in the average SF-6D utility scores of patients at 5 months after cardiac surgery, and these findings might support those of the previous study [21].…”

“…However, a recent study reported that although their results did not differ significantly based on age, sex, emergent status, or history of heart failure or arrhythmias, participation in CR was of more benefit to the patients who underwent cardiac surgery [29]. In addition, we previously reported that no age-related differences in health utility were found between middle-aged and older patients upon entrance into a phase II CR program at 1 month and at 3 months after cardiac surgery [21].

“…The higher the limitation in each domain, the higher the subtraction from the baseline. After we assessed the patients with the SF-36, the scores were converted to mean SF-6D utility scores by iHope International Co. Ltd. (Kyoto, Japan) based on techniques used in previous reports [17,19,20,21].…”

“…The Short-Form Six-Dimension (SF-6D), an instrument that provides a summary score based on the Short Form-36 (SF-36), was recently developed [17,18,19,20] to enlarge the bases for economic evaluations while retaining the descriptive richness and sensitivity to change of the SF-36 [17,18,19,20]. Previously, we tried to identify and compare age-related differences in health utility assessed by mean SF-6D utility score in 62 cardiac surgery patients at 1 and 3 months after cardiac surgery [21]. However, we could find no evidence of a relation between age-related differences and health utility assessed by the SF-6D in the chronic phase following cardiac surgery.…”

Background Daytime sleepiness can be assessed by the Epworth Sleepiness Scale (ESS), which is widely used in the field of sleep medicine as a subjective measure of a patient’s sleepiness. Also, health utility assessed by the mean Short-Form Six-Dimension (SF-6D) score, one of several preference-based utility measures, is an important measure in health care. We aimed to examine age-related differences in daytime sleepiness and health utility and their relationship in patients 5 months after cardiac surgery. Methods; This cross-sectional study assessed 51 consecutive cardiac surgery patients who were divided into a middle-aged (<65 years, n = 29) and older-age group (≥65 years, n = 22). The mean ESS and SF-6D utility scores were measured at 5 months after cardiac surgery and compared. In addition, the relationship between ESS and SF-6D utility scores were assessed. Results; There were no significant differences between the middle-aged and older-aged groups in either the mean ESS (5.14 ± 2.96 vs. 4.05 ± 3.23, p = 0.22) or SF-6D utility (0.72 ± 0.14 vs. 0.71 ± 0.10, p = 0.76) scores. However, there was a negative correlation between both values in all of the patients after cardiac surgery (r = −0.41, p = 0.003). Conclusions; Although there were no age-related differences in the ESS and SF-6D utility values between the two groups, there was a negative correlation between these values in all patients at 5 months after cardiac surgery. This suggested that sleepiness is associated with decreased utility scores in patients at 5 months after cardiac surgery.
