Online case discussion with CPMS

In order to exchange opinions on complex and rare cases, clinicians from ERN member hospitals can gather in multidisciplinary expert panels, viewing and discussing a given case online. Bundling knowledge and experiences and consequently lowering the need for patients to travel is an essential goal of the ERNs.

The tool to conduct online discussions in a secure manner is the CPMS (Clinical Patient Management System).

Any case that falls within the disease scope of ERN-RND can be discussed within suitable expert panels in CPMS. In addition, we cooperate with the MLD initiative to help clinicians with difficult treatment decisions for MLD patients via a structured discussion process (MLD treatment eligibility panels).

What is the CPMs ?

The CPMS enables case discussions for multi­disciplinary expert panels.

Who can use it ?

Clinicians affiliated with an ERN hospital or clinicans reffering their patients to ERN hospitals

What is the CPMS?

The CPMS is a secure IT platform used to support the European Reference Networks in the diagnosis and treatment of rare or low prevalence complex diseases across national borders.

Health professionals can upload relevant patient data, images and examination findings as well as discuss the case in the panel of experts.

For this purpose, CPMS includes a consultation form with an adapted data structure, integrated DICOM viewer and a video conferencing tool. This enables the description of a patient case in a comprehensive manner.

By providing a structured and safe environment to exchange opinions, CPMS facilitates and intensifies the collaboration between expert centres within the European Reference Networks.

If due to a particularity of a certain patient case, additional expertise is needed that is not available in the given ERN, the case can be forwarded to another ERN, so that the relevant experts can discuss it or give their opinion (e.g. a case with intellectual disability traits can be moved to ERN-ITHACA to obtain specific advice from ITHACA‘s experts).

Similarly, the panel lead (clinician having entered the case) or the panel manager (CPMS Helpdesk) can invite individual experts from other ERNs to participate to a scheduled online discussion or to give their opinion, if they deem that this can be of added value.

In the near future, rare disease care pathways will be implemented at the regional or national level. These pathways will regulate which patients will be discussed in CPMS (gatekeeping function). ​

This short video here illustrates the goal and the added value of using the CPMS.

Who can use it?

You are a clinician working in a hospital member of an ERN:
Clinicians working in ERN Full Member and Associated Partner hospitals can have direct access to the CPMS. Please follow the instructions given in the section. - „How to use it /best practise?“​.

You are a clinician working in a EU/EEA hospital non-member of an ERN:​
You can refer your patient to the relevant ERN member hospital so that (s)he can get access to the ERN-RND expertise or request a CPMS guest access.

Examples of guest users are:

  • The 'Point of Care specialist' (treating doctor) of a patient referred to the CPMS.​
  • Health professionals who need to upload patient data to a panel in agreement with an ERN Member or Affiliated Partner;
  • Health professionals who are needed on a case by case basis, because of the clinical expertise they can bring to the specific consultation panel to which they are invited.

​The CPMS is not directly accessible to individual patients.

MLD Treatment eligibility panel

Treatment with hematopoietic stem cell transplantation or gene therapy is only beneficial in early disease stages of MLD. Determining which patients might benefit from treatment and which do not, can be difficult. Therefore, an international MLD treatment eligibility expert panel can be consulted, consisting of expert members of ERN-RND and the MLD initiative. When there is a need to discuss a case, the panel is convened on an ad hoc basis.

Cases eligible for discussion include patients with a confirmed diagnosis of MLD for whom possible benefits of treatment with hematopoietic stem cell transplantation or gene therapy are not straightforward. Also pre-symptomatic cases can be discussed.

All physicians in Europe are encouraged to discuss these cases with this panel. If you would like to discuss a case please contact the ERN-RND CPMS helpdesk.

A detailed description of the procedure can be found in the standard operating procedure:

Neuroradiology Expert Advice Panel

Neuroradiology expert advice for diagnostic and management decisions

ERN-RND has established a standard pathway for providing expert neuroradiological advice across sites.

Our ERN-RND member HCPs (and affiliated partners) are encouraged to contact us for any RND case for which they would like a second opinion as a basis for individual recommendations for diagnostic and management strategies to optimize patient care.

Possible scenarios for which clinicians might want to use this offer include (but are not limited to):

  • Child with mild developmental delay: benign / onset of disease? -> cMRI: delayed brain maturation vs. (subtle) structural abnormalities
  • Child with delay + subtle signs: acquired / genetic? -> cMRI: acquired disease, e.g. CMV infection / TORCH vs. likely genetic
  • Acutely ill patients with suspected encephalopathy -> cMRI: secondary, e.g. infectious / para-infectious vs. metabolic / genetic
  • Cerebellar syndrome with fast progression -> cMRI: secondary, e.g., cerebellitis vs. genetic
  • Patient after pharmacological treatment showing brain volume reduction -> cMRI: side effects vs. neurodegenerative / neurogenetic disease
  • Any RND patient with imaging findings that might benefit from a second opinion

To make use of this opportunity, imaging data must be provided via CPMS. Advice will be provided in a virtual meeting between the referring physician plus the initial neuroradiologist and a dedicated ERN-RND neuroradiological expert clinician (and further experts if necessary. Meetings are facilitated by the ERN-RND CPMS helpdesk.

You are working for an ERN-RND member or affiliated partner and would like to receive neuroradiology advice for one of your patients? Please contact the CPMS helpdesk.
