Abstract

Objective: The aim of this study was to evaluate psychological distress in patients on chronic hemodialysis.

Subjects and methods: A total of 72 patients on chronic hemodialysis were enrolled in this study. We evaluated psychological distress by using the K6 questionnaire, health-related quality of life (HRQOL) by using the EQ-5D questionnaire, and clinical parameters. Among the 72 patients, we also evaluated changes in K6 scores in 58 patients at 1-year follow-up.

Results: The mean K6 score was 3.7 ± 3.7 and 2 subjects (2.8%) were defined as having psychological distress. K6 scores were significantly correlated with body fat percentage, albumin level, and EQ-5D scores in total subjects. K6 scores were also significantly and negatively correlated with EQ-5D scores in men and women. In the 1-year follow-up group, changes in K6 scores were weakly and negatively correlated with changes in EQ-5D scores.

Conclusion: Psychological distress was closely associated with HRQOL in patients on chronic hemodialysis. Coping strategies for psychological distress might be useful in improving HRQOL in patients on hemodialysis.
