Patient pathways for rare liver diseases: a European template developed by ERN RARE-LIVER

Rare liver diseases are associated with diagnostic delay, fragmented care, inconsistent management, and limited patient support. Patient pathways may help address these challenges by translating clinical guidance and patient priorities into practical, coordinated care processes.

This manuscript presents a European template for developing patient-centred pathways for rare liver diseases within ERN RARE-LIVER. The template was developed through multidisciplinary collaboration involving hepatologists, specialist nurses, patient representatives, patient organisations, and EURORDIS, and was informed by clinical guidance, patient-journey principles, and iterative expert and patient review. The proposed framework follows four phases of the patient journey: pre-diagnosis, diagnosis, management, and long-term follow-up. It includes disease-specific sections, educational resources, frequently asked questions, and "10 key questions" to support shared decision-making. Pathways for non-cirrhotic portal vein thrombosis, polycystic liver disease, and portosinusoidal vascular disorder illustrate the practical application of the template.

This European template provides a practical, adaptable framework aimed at supporting harmonised, multidisciplinary, and patient-centred care for rare liver diseases across European healthcare settings. Future work should evaluate implementation, usability, and impact on care coordination and patient experience.
