Investigation of the Relationship Between Frailty, Sarcopenia, Malnutrition, and Psychosocial Parameters and Post-Transplant Outcomes in Liver Transplant Candidates

This study will evaluate frailty, nutrition, sarcopenia, and psychological health in people waiting for a liver transplant. The purpose is to understand how these factors affect outcomes before and after transplantation. By identifying patients at higher risk early, the study aims to support the development of better care programs in the future. Participants will complete simple tests of physical strength, walking speed, and daily activity levels. Their nutrition and psychological well-being will also be assessed. The study will then look at how these results relate to medical scores used in liver disease and to outcomes after transplant, such as hospital stay, complications, or survival. Adults aged 18-65 years who are on the liver transplant waiting list and can understand Turkish are eligible to join.
