In 2014, we described the vision of a ‘Green Button’ for using aggregate patient data at the bedside in Health Affairs.

In 2015, we outlined the steps in realizing the green button vision, and for bringing cohort studies to the bedside.

In 2016, we built a search engine for patient timelines for rapid phenotyping to build cohorts of similar patients.

In 2017, we obtained IRB approval and philanthropic support for a pilot of the green button vision. 1 min video.

In 2018, we outlined the methods that enable the informatics consult service and wrote a perspective on why a “speciality service” (and not a physical button in the EHR) is the right approach for realizing our vision.

In 2019, we completed the pilot study.

In 2020, we released the Advanced Cohort Engine for searching longitudinal patient records, which made the service possible.

In 2021, we published the results of the pilot study.
