Abstract
BACKGROUND: As patient and graft survival rates have been improving after kidney transplantation, health-related quality of life (HR-QOL) has become an important indicator of effective treatment. This study aimed to evaluate changes in HR-QOL after kidney transplantation. MATERIALS AND METHODS: The KoreaN cohort study for Outcome in patients With Kidney Transplantation (KNOW-KT) is a multicenter, observational, 9-year, cohort study. The HR-QOL of patients in the KNOW-KT study was assessed before transplantation and 2 years after transplantation using the Kidney Disease Quality of Life Short Form (KDQOL-SF) including chronic kidney disease targeted area and the Medical Outcome Study 36-item Short Form Health Survey (SF-36). Multivariate linear regression was used to identify significant factors associated with follow-up QOL scores. RESULTS: A total of 175 patients from 8 centers were analyzed. All QOL scores including the total QOL score, chronic kidney disease targeted score, and SF-36 at the 2-year follow-up were significantly increased compared to baseline values. Both physical and mental scale scores were improved after transplantation. CONCLUSION: The QOL scores for both the mental and physical scales were improved at 2 years after kidney transplantation. High glomerular filtration rate at 2 years, high baseline QOL score, and low body mass index were associated with good follow-up QOL scores. Kidney transplantation for an Asian population with end-stage renal disease can result in better QOL as well as better patient and graft survival.
