Re: "Global challenges require global cooperation," (The Hill Times, May 31). It is encouraging to see stronger calls for open science and the creation of an environment that will allow for greater data sharing. The editorial written by Dr. Mona Nemer and Dr. Roseann O'Reilly Runte on May 31 served well in amplifying those calls. Data sharing isn’t a novel idea—but there’s a reason it has remained a ‘pipe dream’ for so long. Barriers like asking patients for permission to share their data and the lack of trust among researchers and between institutions have challenged our collective ability to create collaborative systems where data can be shared. For the last 10 years, the Ontario Brain Institute has been working diligently to translate this dream into reality through Brain-CODE—a platform that places a priority on patient privacy and data security giving researchers the confidence and ability to collaborate on an international playing field. We’ve worked with the information and privacy commissioner of Ontario to design a highly secure structure with an underlying robust and scalable data governance model. The results of these efforts saw OBI as the first research institute being presented with the privacy by design ambassador designation for adhering and committing to a rigorous framework of data privacy and security. We agree. Let the lessons we’ve learned over the last year, and the breakthroughs we’ve witnessed, transform the way we conduct research. In other words, we’re hopeful this platform will serve as a best-in-class example of how we can make seemingly rare breakthroughs like the COVID-19 vaccine, a more regular occurrence across multiple disciplines.
