What is MSSanté ?

MSSanté is an ensemble of secure messaging services offered by the ANS. The protection of patient data is essential to the development of eHealth systems. The day-to-day concern of health and social care professionals to keep sensitive health data confidential shapes professional practices and requires constant vigilance when it comes to sharing patient information.

Electronic transfers need to be secure to guarantee high-quality, coordinated treatment that respects the patient’s right to privacy. The interoperability of secure health messaging services enables MSSanté systems to play a key role in protecting exchanges within a secure shared space.

In order to meet interoperability criteria, your digital messaging project must be an end-to-end solution that allows:

  • Sharing information from the patient’s medical file, transmitted by an authorised professional, to the patient’s medical file managed by an authorised professional on the receiving end;
  • Or sharing information from the authorised professional who sends it directly to the patient’s medical file in their Mon Espace Santé (My Health Space) account.

With MSSanté, you will develop solutions that meet the latest legal regulations and guarantee a safe access to trusted sharepoints, across the network of exchange channels in the medical field.

The ANS supports you through the process of setting up secure messaging services and actively works to integrate these messaging services in the software solutions used by health professionals.
