BACKGROUND: Datathons facilitate collaboration between clinicians, statisticians,
and data scientists in order to answer important clinical questions. Previous
datathons have resulted in numerous publications of interest to the critical care
community and serve as a viable model for interdisciplinary collaboration.
OBJECTIVE: We report on an open-source software called Chatto that was created by
members of our group, in the context of the second international Critical Care
Datathon, held in September 2015. METHODS: Datathon participants formed teams to
discuss potential research questions and the methods required to address them.
They were provided with the Chatto suite of tools to facilitate their teamwork.
Each multidisciplinary team spent the next 2 days with clinicians working
alongside data scientists to write code, extract and analyze data, and
reformulate their queries in real time as needed. All projects were then
presented on the last day of the datathon to a panel of judges that consisted of
clinicians and scientists. RESULTS: Use of Chatto was particularly effective in
the datathon setting, enabling teams to reduce the time spent configuring their
research environments to just a few minutes-a process that would normally take
hours to days. Chatto continued to serve as a useful research tool after the
conclusion of the datathon. CONCLUSIONS: This suite of tools fulfills two
purposes: (1) facilitation of interdisciplinary teamwork through archiving and
version control of datasets, analytical code, and team discussions, and (2)
advancement of research reproducibility by functioning postpublication as an
online environment in which independent investigators can rerun or modify
analyses with relative ease. With the introduction of Chatto, we hope to solve a
variety of challenges presented by collaborative data mining projects while
improving research reproducibility.
