Context

The Metropole Nice Côte d’Azur (MNCA) launched an initiative starting in 2021 to study the environmental, social and economical factors influencing the health of its citizen. The 3IA Côte d’Azur was part of this initiative through a collaborative project gathering the MNCA, the University Hospital of Nice, and the economy laboratory of University Côte d’Azur. The mid-term objective of this initiative is to provide geo-localized information helping the guidance and evaluation of public policies. A first use case of this project, aimed at identifying the geographical disparities of breast cancer screening for women aged from 50 to 74 in the department of Alpes-Maritimes. We make this analysis at the scale of the smallest available administrative territory (IRIS) as defined by French national statistics Institute (INSEE), it allows to have enough statistical information at smallest area and avoid working on individuals’ data subject to GDPR.

Data qualification

A first task of the 3IA Côte d’Azur was to perform data qualification of various open or restricted databases provided by public French institutions (INSEE, IGN, CPAM06, CAF06, MNCA, CHU Nice). Databases were related to 5 major themes (transport, demographics, environment, healthcare, and geography) and they have been audited to detect missing values, outliers and inconsistent data between several databases. After data cleaning, databases were visualized and analysed by the various partners of the project.

Accessibility to screening centers

The 3IA Côte d’Azur has also participated in the study of the difficulty to access screening centers through personal vehicles or public transportation at different locations of the department of Alpes-Maritimes. More specifically, the estimation of various accessibility indices to reach certified radiological centers for breast cancer screening was performed as shown the maps below.
