Brest University Hospital

Challenge

Each in their own way, Roche, the Brest University Hospital and Octopize have identified a crucial need in their activity: to improve the sharing of health data. According to Adrien Bussard, innovation manager at the Brest University Hospital: “We noted difficulties in sharing data for various research or innovation projects. [...]”

The aim? Facilitate partnerships between manufacturers and healthcare institutions by allowingdata quality assessment prior to an acquisition.

Solution

• Octopize's personal data anonymization solution made it possible to Unleash data sharing from the Brest University Hospital to the Roche laboratory.
• To allow the sharing of this sensitive data, Octopize transmitted a new set of synthetic and anonymous data generated from the original data.
• Roche was then able to Evaluate the value of datasets of the Brest University Hospital thanks to the faculty of the avatar method at maintain statistical properties of the original dataset as well as its variability without compromising the confidentiality of the patients who are the source of the data.

Setting up

Anonymization service provided by Octopize.

Maintaining statistical quality & utility

• The generated data maintains the same relational table structure as the original data
• Each summary table has the same number of rows and the same number of columns.

→ The synthetic data generated can be used without modification in the same pipelines as the original data

In this diagram, the white areas represent missing data and each vertical bar represents a column in the data set.

This comparative graph illustrates that the synthetic data generated maintains the pattern of the missing data.

This comparative graph illustrates that the synthetic data generated maintains the distributions of the original data.

ROI

• Acceleration the acquisition period from 6 months to 1 year
• Sharing of the informative value of the data
• Solving information asymmetry
• ROI guarantee of a partnership
• Valorization data for secondary uses without new consent
