Standard Project

Once authorization has been obtained, access to confidential data through the CASD must be preceded by 2 formalities:

  1. Signing of contracts
  2. Participation in an enrolment session


The CASD is a paid service that must be contracted in advance.
The contractual file is composed as follows:


Signed by the legal representatives of the institutions involved in the project.

A signatory institution financing, via Purchase Order(s), your use of the CASD and/or SD-Box access point(s) is qualified as a “Funder“.  The access point(s) funder may be separate from the project funder. There may be several identified access point funders. On the other hand, there can only be one single funder for services related to a single project. A signatory institution issuing SD-Box Hosting Vouchers (CASD access point) will be referred to as a “Hosting Company“. It may be identical to the funder. If you wish to benefit from several access points (which can be distributed in different establishments), there will be as many Hosting Vouchers as SD-Boxes deployed (each signed by the identified host).


The Purchase Order(s) signed by the person authorized to incur the expenses of the “Funder” of your project and/or an SD-Box access point, negotiated in advance with our services according to your needs and the current price list.

The Access Point Hosting Voucher(s) signed by the legal representative of the entity(ies) identified as the “Hoster(s)” of an SD-Box

The technical form, available on our website, to be completed online for hosting an SD-Box.


Signed by each of the project members during the enrolment session that each user must attend. This document governs the “Use of the service” aspects. There will be as many CGUs as there are users.

Price example

Either a project launched on 01/08/2018 and carried by a team of 2 users including 1 PhD/postdoc* for a duration of 12 months (minimum delay for a new project) and requiring a work environment in configuration 1 (i.e. 2 vCPU, 8 GB of memory and 200 GB of disk).

In addition, the institution financing the project would like 2 access boxes (SD-Boxes) to be deployed for 12 months from 1 August 2018, to be used in particular by the above project to access the data.

*a “student access” reduction of 50% is systematically applied to the monthly subscription fee for the last user access upon presentation of the corresponding proof.

Under these conditions, the amount invoiced to the Financing Institution would amount to € 2,723.00 for the first 12 months of subscription, according to the following estimate :

PMSI Project

CASD provides a secure service for making hospital stay data available (ATIH’s PMSI databases – Programme de Médicalisation des Systèmes d’Information -). Each use of the data (project) is made within the framework of a secure bubble made available with a software environment, agreed with the users of the project, so that the processing takes place entirely in-situ, in order to guarantee the protection and traceability of the data. To access PMSI data, it is necessary to follow an authorization and implementation procedure described below.


Since the entry into force of the new Health Act and the establishment of the National Institute of Health Data (INDS), the administrative circuit for CNIL authorization requests relating to health data has been modified. For more information, visit the NSDS (National Health Data System) website. Any request for processing of PMSI databases requires in advance that the controller (RT) obtain authorisation from the CNIL and/or declare himself/herself in compliance with a reference methodology (MR) approved by the CNIL.

This authorisation or declaration of compliance to the MR does not concern the Implementing Party (RMO) who carries out the processing on behalf of the RT.
However, the RMO must have submitted a compliance commitment to the CNIL in accordance with the provisions of the decree of 17 July 2017 relating to the standard determining the criteria of confidentiality, expertise and independence for research laboratories and design offices.

Once the necessary administrative procedures have been completed (CNIL or INDS), it will be necessary that :

  • the RT signs an agreement with the ATIH in which it will identify in particular the RMO(s) to which it will have recourse in the processing operation
  • the RMO signs an agreement with the ATIH in which it will specify the fields of the PMSI (MCO, SSR, HAD, Psy) and the periods requested by completing the basic ATIH application form (annex to the RMO-ATIH agreement)

We invite you to visit the ATIH website for more information.


To access the PMSI, here are the steps to follow:

Simulation of CASD quote


Generate a quotation proposal using CASD’s online quotation simulator and send it to to refine it with our teams according to your needs and allow us to draw up a final quotation (for more details, see the paragraph “Generate a quotation proposal” below).

Preparation of the final CASD quotation


Validate and sign the final quotation sent by the CASD.

ATIH Agreement
ATIH Basic Request Form


Retrieve the database request form from the ATIH website and complete it. The reference of the estimate sent by the CASD as well as its amount will be recorded in the field provided in this document. Then send the completed form to ATIH for validation.
NB: The completed form will be inserted as an annex to the agreement with ATIH (see above).

Contractualization with CASD


Contract with the CASD so that your company can finance your access(s) through the CASD and host one or more SD-Boxes. A master service contract and a hosting voucher by SD-Box will be sent to you. They will be returned to us signed by a legal representative of the company.

Enrolment and sending of the access box


Participate in an information and awareness session (called an enrolment session) during which you will be provided with a smart access card after signing the user contracts. To do this, it is necessary to register via the registration tab enrolment session.

Access to data


Access the data through the access box sent by the CASD once steps 4 and 5 have been validated.


The invoicing of access to PMSI data via CASD is disconnected from the right to use the data granted and invoiced by ATIH.

The CASD charges the costs associated with accessing PMSI data (see example below).

In order to support you as best as possible in establishing a secure access offer adapted to your needs, we offer you an online quotation simulator.

In order for us to meet your needs as soon as possible, please follow the following steps:


First, the simulator generates a proposal for a quote based on the information you enter. This proposal does not constitute a binding offer on our part and is therefore not binding.


If you consider that your quotation simulation best reflects your needs, please send a message to indicating the number of this quotation simulation as a reference and/or attaching it as an attachment to your message.


CASD teams will come back to you to confirm or refine your request before generating a final quotation which, once signed by the person authorized to incur expenses within your institution, will be considered as an official order form.

EXAMPLE (for information only)A project run by a team of 4 users for 6 months, requiring an access box (SD-Box) and having a “VM1” configuration (2 cores, 16 GB RAM and 500 GB disk space), would cost a total of 2 454.00 EUR, or 613.50 EUR per user to have access to the PMSI data over this period.

Below, for this example, the breakdown of the cost items from the price list corresponding to the minimum elements to be implemented:

  • Rental and maintenance of the SD-Box access point over 6 months: 6 x 35.00 = 210.00 €
  • A 6-month monthly subscription for each of the 4 users, including participation in an enrolment session, delivery of individual access cards, creation of associated accounts and first-level support over this period : 4 x 6 x 29.00 = 696.00 €
  • The monthly rental of 6 months and the associated maintenance of the dedicated project space (operating system, server space, virtual machine, statistical processing software included in the base*) : 6 x 258.00 = 1 548.00 €

* Base: R and R Studio, Stata, Latex, openoffice, microsoft office (with user license supply), SAS (if user-provided CASD environment license and usage right certificate)


Additional options are also available, depending on the needs expressed by users. You can consult them on our rates page.

In addition to these fixed costs, additional fees will be applied for any request to upgrade the initial configuration and for the installation of off-premise software (subject to technical feasibility). Please contact us directly if necessary:


“English translation soon… In the meantime, you may visit CONSTANCES official website:

La cohorte CONSTANCES est constituée d’un échantillon aléatoire de plus de 200 000 volontaires âgés de 18 à 69 à l’inclusion, dont la structure est proportionnelle à la population pour le sexe, l’âge et la catégorie sociale. L’inclusion des volontaires a lieu dans un des 21 Centres d’examens de santé de la sécurité sociale participant au projet qui offrent une répartition géographique permettant de représenter les principales régions françaises. Les données recueillies lors de l’inclusion et tout au long du suivi couvrent divers domaines : données de santé issues d’examens de santé, de questionnaires et de données du SNDS (données de remboursement de soins, d’affections de longue durée) et d’hospitalisation ; données de comportements (tabac, alcool, alimentation, exercice physique), données socioéconomiques transmises par la Cnav. (

La cohorte GAZEL a été mise en place en 1989 auprès des salariés d’Électricité de France-Gaz de France (EDF-GDF). En 1989, GAZEL a recruté 20 625 volontaires travaillant à EDF-GDF alors âgés de 35 à 50 ans (15 011 hommes et 5614 femmes). La cohorte est diversifiée en termes de statut social, économique et professionnel, de santé et de comportements liés à la santé. Les données collectées couvrent diverses dimensions et proviennent de différentes sources : questionnaire auto-administré annuel, service du personnel d’EDF-GDF pour les caractéristiques sociales, démographiques et professionnelles, régime spécial de sécurité sociale, médecine du travail, SNDS (soins de ville et hospitaliers, causes de décès), Centres d’examens de santé de la sécurité sociale. Une biobanque est associée à la cohorte. (

L’Unité Cohortes épidémiologiques en population UMS 11 (directrice : Pr. Marie Zins) a la responsabilité de ces deux cohortes.

Le CASD fournit un service sécurisé de mise à disposition des données des cohortes CONSTANCES et GAZEL. Chaque utilisation des données (projet) se fait dans le cadre d’une bulle sécurisée mise à disposition avec un environnement logiciel, convenu avec les utilisateurs du projet, de sorte que les traitements s’effectuent entièrement in-situ, afin de garantir la protection et la traçabilité des données.

Pour avoir accès à ces données, il est nécessaire de suivre une procédure d’habilitation et de mise en place décrite ci-dessous.

Votre demande a été validée par la cohorte épidémiologique en population

Soit un projet lancé au 01/08/2020 et porté par une équipe de 2 utilisateurs pour une durée de 12 mois (délai minimum pour un nouveau projet) et nécessitant un environnement de travail en configuration 1 (soit 2 vCPU, 8 Go de mémoire et 200 Go de disque).

Par ailleurs, l’institution Financeur du projet souhaiterait le déploiement pendant 12 mois à compter du 01/08/2020 d’un boîtier d’accès (SD-Box), qui sera notamment utilisé par les deux utilisateurs dans le cadre du projet ci-dessus pour accéder aux données.
NB : La SD-Box est mutualisable.

Dans ces conditions, le montant facturé à l’institution Financeur s’élèverait à 4740.00€ pour les 12 premiers mois d’abonnement :

  • La location et la maintenance du point d’accès SD-Box sur 12 mois : 12 mois x 35.00€ = 420.00€
  • L’abonnement standard comprenant 1 accès utilisateur et la configuration 1 : 12 mois x 238.00€ = 2856.00€
  • Ajout d’un second utilisateur : 12 mois x 37.00€ = 444.00€
  • Option Référentiel de Sécurité de Données de Santé : 12 mois x 2 utilisateurs x 30.00€ = 720.00€
  • Exports automatiques : 12 mois x 25.00€ = 300.00€

Enhance your business data

In the “all-digital” era, data produced and held by companies are an invaluable source of information and an often under-exploited asset. The processing, analysis and security of this data is therefore a crucial issue for these economic operators, whether for prospective purposes, strategic management or adaptation to their competitive sector of activity.

However, the latter do not always have the infrastructure, computing capacity or tools necessary to be able to process this data in compliance with the necessary confidentiality and security rules.

Customized services

CASD offers a wide range of tailor-made services enabling companies to analyse, process or make available to authorised third parties the data they produce, whatever the volume, under optimal security and working conditions.

These services are based on a contractual and technical system that guarantees the confidentiality of data throughout the chain – from their storage within our infrastructure to their availability and use by authorized users. All this in a customised and completely secure workspace. (see the price list of our services)

Contact us for more information

Many private actors – in banking, insurance, energy, transport, etc. – are already involved. (see our references) – have trusted CASD and Datastorm to carry out their projects.

For any information, do not hesitate to contact our partner Datastorm or our service dedicated to the private sector.
