Lead Data Warehouse Developer Description

Nice to meet you

We are i2i, a young, ambitious, goal-oriented and intelligent organization based in Amsterdam, which focuses on one of the most important societal challenges in healthcare: improving cost-effectiveness and quality in healthcare. How can we ensure that we achieve the best return on every euro invested in healthcare? We have developed the 'Effective Direct Declaration of Partnership' (DDD-Partnership) model, which rewards care providers who provide proven sensible care. The trust between insurer and care provider is thereby increased, the administrative burden is reduced and the health care funds are demonstrably spent sensibly.

With over 30 colleagues, we work together with hospitals, pharmacies and mental healthcare institutions on sensible care. These healthcare providers realize benefits for them such as better purchasing conditions, fewer administrative burdens, improvement of internal processes and an (even) better social image. Every day i2i is in conversation with medical specialists aimed at realizing a behavioral change in cost effectiveness and quality of delivered care.
