Quality of Life and Well-Being in Adults With Fontan Physiology: Findings From the Australian and New Zealand Fontan Registry Quality of Life Study.

BACKGROUND

To characterize global and health-related quality of life (QOL) among adults with Fontan physiology enrolled in the Australian and New Zealand Fontan Registry (ANZFR), and identify sociodemographic, clinical, psychological, and relational factors associated with outcomes.

METHODS AND

RESULTS

Using a cross-sectional survey design, 66 adults with Fontan physiology (58% women; mean age, 29.6±7.7 years; range, 18-50 years) completed validated self-report measures. Health-related QOL was assessed using the Pediatric Quality of Life Inventory, and global QOL was assessed using a visual analog scale (0-10). Participants reported lower total health-related QOL (P<0.001), as well as lower physical (P<0.001) and social (P=0.002) functioning compared with normative data. Median global QOL was 7.0 (interquartile range: 5.0-8.0) and most participants (71%) rated their QOL ≥6. For health-related QOL, age, sex, university education, and length of hospital stay in the past 12 months explained 27% of the variance in scores, while general psychological stress, medical traumatic stress, communication problems, and access to emotional support explained a further 44% of variance (final model: 71% of variance explained). For global QOL, sociodemographic and clinical factors explained 20% of the variance in scores, while psychological stress and sense of coherence explained a further 24% (final model: 44% of variance explained).

CONCLUSIONS

Adults with Fontan physiology reported lower overall health-related QOL compared with community-based norms. Variance in QOL outcomes were predominantly attributable to psychological and relational factors. Tailored screening and assessment to identify Fontan patients at greatest risk of lower QOL, and a proactive approach to supportive care, are needed.
