WHAT ARE THE GOALS OF THIS HACKATHON?

The Gravitate Health project, now in its fifth and final year, has developed a federated open-source platform (FOSP). The goal of Gravitate Health is to empower and equip Europeans with health information for active personal health management and adherence to treatment.

The Hackathon provides a great opportunity to showcase the platform and invite participants to test its usability and build on it and contribute to its improvement. Constructive feedback on further development and new ideas will be very valuable.

The ePI (electronic product information), interoperability, and the FHIR standard are in the center of development of the FOSP, one of the main outputs of  Gravitate Health.

Among the aims of the project is also to stimulate public-private partnerships to:

(i) Create market-specific applications which can accommodate specific needs of national or local ecosystems.

(ii) Build commercial solutions to serve specific disease areas and add value to the platform.

By creating lenses, you will contribute to the sustainability of Gravitate Health vision opening opportunities for the creation of new markets.  

WHERE DOES THE HACKATHON TAKE PLACE?

The Hackathon is held in Athens, at Divani Caravel Hotel, at the city centre. 

Remote participation in the Hackathon is open, and we encourage individuals to join online or even teams to form in remote locations and connect to the event in Athens. 

THE VENUE

Divani Caravel Hotel | 2, Vasileos Alexandrou Av., 16121, Athens, Greece 

WHAT CHALLENGE WILL BE ADDRESSED AT THE HACKATHON?

In the context of Gravitate-Health project, one of the most prominent objectives is to provide patients with the information they need about their medications. However, this information needs to be adapted to the context and preferences of the end-user to achieve effective and optimal understanding.  

A lot of progress has been made since Hackathon #1, and now there are many annotated ePIs, the Gravitate Health Implementation Guide (IG), and several lenses. 

At Hackathon #2 the challenge will be to design more lenses and contribute with more ideas on lenses-i.e. how to personalise medicines information.

More specifically, to Develop G-lenses (a ‘G-lens®’ is a piece of code which encodes certain knowledge required to better adapt the content of product information) using:

(1) the Gravitate Health FOSPS*,

(2) ePIs with embedded semantic annotations (using standard terminologies such as SNOMED-CT, LOINC, ICD 10, iCPC-2),

(3) a persona vector i.e., the information relevant to the patient’s health in an International Patient Summary-IPS, and

(4) the patient’s current context and preferences; create a lens that effectively and optimally adapts the content to preferences and context to provide the patient with relevant information about his/her medicines.

*FOSPS: federated open-source platform services
