Table 1. Five Keywords Indicating Information on Non-medical Resources.

From: Evaluation of Clinical Practice Guidelines for Rare Diseases in Japan

Keywords Explanations
Intractable Disease Consultation Support Center The centers offering support to address psychological and social issues, which are in each prefecture to support their daily lives and to improve the quality of life for patients living with rare/intractable disease in the community (43). The centers offer services such as consultation and information provision on formal support programs available to patients living with rare/intractable disease, promoting social engagement, organizing employment support through counseling for adaptation to the workplace and arranging employment opportunities, coordinating of peer supports, and holding workshops for the patients and their family (43), (44).
Japan Intractable Diseases Information Center Information support by a MHLW project, which is the reference source on rare/intractable diseases online. The website is designed to allow access equally to stakeholders on information about incurable diseases. The website contains information such as various Acts or Programs for rare/intractable diseases, designated rare/intractable disease projects, national research projects, clinical trials, centers of experts, patient associations, practice guidelines, and knowledge for the public (45).
Patient Association Peer support. Informational, educational, psychological, and practical support based on extremely similar illness experiences (46).
Medical Subsidy System Financial support as regulated by the Rare/Intractable Disease Act. Patients with rare/intractable disease are required to submit a clinical survey form, which is marked by a designated rare/intractable disease clinician, to the local healthcare center in each prefecture. When the criteria for financial support are met, the patient is eligible for the support (47).
Designated Rare/Intractable Diseases A term indicates the diseases subjected to the medical subsidy system regulated by the Rare/Intractable Disease Act (47). This term can serve as a signpost to make healthcare providers aware of non-medical resources available to patients living with rare/intractable diseases. The term also indicates the organization of national specialized research groups for each disease to overcome it (28), (45), (47).
