A call for proposals for the drafting of Diagnostic and Care Protocols (PNDS) will be launched by the Direction Générale de l'Offre de Soins (DGOS) in the second quarter of 2026, in conjunction with the 4th National Plan for Rare Diseases 2025–2030.
Do you have an idea or a project? Please do not hesitate to contact Aurélie COUSSAERT, the network's PNDS liaison officer: aurelie.coussaert@chu-lille.fr
In compliance with the missions entrusted by the DGOS and with National Rare Disease Plan 3, FIMATHO is committed to providing methodological support in order to support and coordinate the drafting of National Diagnosis and Care Protocols (Protocoles Nationaux de Diagnostic et de Soins (PNDS)). These protocols are drafted by the Rare Disease Reference Centres (Centres de Référence Maladies Rares (CRMR)) of the network under national supervision and with cross-CRMR and cross-network project coordination, in collaboration with patients associations.
WHAT IS A PNDS?
A PNDS is a reference guide for health care professionals (primary care physicians or specialists, National Health doctors as well as physicians from the competence centres).
Its objectives are to explain:
- optimal care and treatment, and it must be clear, concise and contain the most up-to-date knowledge
- the care pathway of a patient with a recognised long-term illness
It includes several documents: a detailed guide (PNDS), a scientific overview, a summary for the treating physician and if needed, a list of acts and services (or Liste des Actes et Prestations, LAP)
It is based on published international recommendations, which will be listed in the scientific overview.
PNDS protocols are available for all and published on the websites of the Haute Autorité de Santé (HAS or French Health Authority), rare disease health networks, reference centres, patients associations, etc.

What is the methodology for developing a PNDS?
HAS has implemented a methodological guide "Method for developing national diagnosis and care protocols for rare diseases."

EXCEPTIONAL FUNDING FOR PNDS PROJECTS IN 2024
The FIMATHO network is providing exceptional funding for several PNDS (National Diagnostic and Care Protocol) projects, to be carried out by the network's centres of reference or competence.
The projects have been examined by the network's management and scientific committees.
The FIMATHO network has therefore decided to support 9 projects in 2024.
The 9 PNDS projects supported are:
- Oesophageal achalasia (CRACMO) Dr Aumar, Lille
- Familial adenomatous polyposis (MaRDi) Pr Mas / Pr Saurin, Toulouse / Lyon
- Chronic Pseudo Intestinal Obstruction in adults (MaRDi) Pr Joly / Pr Gourcerol, Paris Beaujon / Rouen
- Congenital Sucrase Isomaltase Deficiency (MaRDi) Pr Hugot, Paris Robert Debré
- Crohn's disease in children (MaRDi) Dr Martinez, Paris Robert Debré
- Hirschsprung's disease (MaRDi) Pr Lamireau / Dr Enaud, Bordeaux
- Gastroparesis in adults (MaRDi) Pr Gourcerol, Rouen
- Cystic lesions of the pancreas in adults (PaRaDis) Dr Napoléon, Lyon
- Giant ophalohepatoceles (Diaphragmatic hernia) Dr Boukhris, Lille
Drafting of these PNDS will begin in 2024, with publication scheduled for early 2025.
A FIMATHO liaison officer is dedicated to the PNDS and provides logistical and practical support to the various teams involved.
