About HSII

Key Dates

The Health Systems Implementation Initiative (HSII) is a new multiyear PCORI initiative to advance the uptake of practice-changing comparative clinical effectiveness research results in care delivery settings.

Through HSII, PCORI will provide funding to HSII Participant healthcare delivery systems to undertake implementation projects to actively advance the adoption of new evidence. These projects will have the goal of promoting the uptake of specific PCORI-funded evidence in practice. PCORI’s Board of Governors has committed an initial investment of up to $50 million to support implementation under HSII.

HSII is intended to facilitate lasting change within participating systems and lay groundwork for broader adoption of evidence-based practices.
