Blisly, a project connecting data science... and health!


The Blisly app, launched by MétéoGlobale in 2016, aims to determine how the weather impacts an individual's health by offering an risk index based on a connection between meteorological variations and the amount of emergency room admissions. The app ultimately seeks to generate a personalized risk index based on the data collected about each of its users' specific medical condition. 

Using CRIM's expertise in big data analysis to make a functional app

CRIM's role in this project was the conception of various components that enable the app's operation.

First, CRIM built a cloud computing infrastructure for the collection of meteorological data coming from different sources. With this infrastructure, the app can follow the evolution of certain key meteorological factors, hour by hour: level of humidity, speed and direction of the wind, atmospheric pressure, temperature variations,...

Then, the Emerging Technologies and Data Science Team conducted a literature review and explored many avenues that could lead to the generation of a risk index based on meteorological data and historical statistical data on ridership in emergency rooms. A model reporting the typical level of emergency room ridership for similar weather variations was developed and deployed. 

How it works

The statistical model built by CRIM detects clusters of meteorological variations combinations, then calculates the average level of emergency room traffic during this specific combination of weather factors, by looking at past data. CRIM's tool uses this correlation to establish a general risk index that corresponds to the average traffic in hospital emergency rooms in similar weather conditions.

CRIM's expertise in cloud computing, web architecture and data science was crucial to realize MétéoGlobale's vision for its Blisly app.

In addition to CRIM, many partners have contributed to various aspects of this project: Sacré-Coeur Hospital, Titan Interactif, SWAT Factory, Environment Canada, Québec's Ministère de l'Économie, de la Science et de l'Innovation (MESI), as well as the National Research Council of Canada. 

Exciting new goals for MétéoGlobale!

MétéoGlobale was founded by meteorologist Jocelyne Blouin and Jean-Charles Beaubois, former weather director at Radio-Télévision belge de la communauté française (RTBF), in Belgium. The company is now working on launching its Blisly app in Belgium, France and Swiss.
