Health literacy profiles in kidney transplanted patients: A cluster analysis.

Background: Health literacy is important in chronic conditions, such as kidney transplantation. Understanding patients' health literacy profiles can assist tailoring follow-up and educational programmes to the health literacy needs of vulnerable kidney transplant recipients. This approach enabled us to cluster patients according to their profiles of challenges and strengths in different health literacy domains.
Objectives: This study aimed to identify different health literacy profiles within kidney transplant recipients and what characterized the different profiles.
Design: Cross-sectional study.
Participants: One hundred ninety-five kidney transplanted recipients were included.
Measurements: We used the self-reported Health Literacy Questionnaire and analyzed using Ward's method (hierarchical cluster approach). We also collected background characteristics and clinical variables, including psychological distress (Hopkins Symptoms Checklist) and perceived health status (visual analogue scale, EuroQol-5D).
Results: The analysis revealed four clusters with substantial differences in health literacy profiles. One cluster's patients had the most challenges in all health literacy domains constituting 24% of the sample. Compared to the other three clusters, this cluster was associated with shorter duration of kidney disease, higher number of patients in dialysis before transplantation, higher percentage of male patients, lower number of kidneys from living donors, higher number of patients not working and higher representation of psychological distress. All four clusters reported the most challenges in the same domain: the ability to critically appraise health information.
Conclusion: In kidney transplant recipients, profiling clusters with the Health Literacy Questionnaire and Ward's method aids in identifying health literacy needs in vulnerable groups, enabling transplant professionals to offer tailored health literacy support.
