About HSII

PCORI hosted a launch event celebrating the award of the first health-systems led implementation projects under PCORI's Health Systems Implementation Initiative (HSII).

Watch the Recording

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

Through HSII, PCORI provides funding to HSII Participant health systems to undertake implementation projects to actively advance the adoption of new evidence. These projects have the goal of promoting the uptake of specific PCORI-funded evidence in practice.

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

HSII includes 42 health system participants. Please explore the HSII Participants webpage to learn more.

HSII Implementation Projects


In October 2024, PCORI announced $37 million in funding for the first set of HSII implementation awards. This includes 24 HSII Implementation Projects and one HSII Pilot Project. The projects are focused on implementing one of two topics based in evidence from PCORI’s research portfolio:

  1. Intensive Lifestyle Treatment for Weight Loss in Primary Care Settings
  2. Appropriate Antibiotic Prescribing for Children with Acute Respiratory Tract Infections (ARTIs)

Please visit the topic pages to learn more about the funded projects.

Funding Opportunities for HSII Participants


PCORI issues Calls for Proposals for HSII Implementation Projects, providing HSII Participants the opportunity to propose projects to promote the uptake of specific PCORI-funded evidence within their healthcare delivery settings. PCORI anticipates releasing new Calls for Proposals annually. 

HSII Participants may visit the funding opportunity webpages below for more information. HSII Participants are encouraged to contact PCORI at HSIIQuestions@pcori.org with any questions about Calls for Proposals. PCORI will update the HSII FAQs to respond to commonly asked questions.

HSII Learning Network


​​​​​The HSII Learning Network provides a venue for HSII Participants to connect with each other and with PCORI as they undertake Capacity-Building and Implementation Projects. All 42 HSII Participants belong to the HSII Learning Network. Through the HSII Learning Network, HSII Participants regularly meet, engage with each other, access supports such as Office Hours with investigators from PCORI-funded research studies, and offer their suggestions and input to PCORI, for example on potential evidence topics to be the focus of implementation.

HSII Participants may access the HSII Learning Network SharePoint webpage.
