Demonstration Studies

PCORI-funded PCORnet Demonstration Studies aim to prove PCORnet capacity, while answering critical research questions. They fall into one of four initiatives: Interventional Studies, Obesity Observational Studies, Patient-Powered Research Network (PPRN) Studies, and Health Systems Studies. While they are all designed to answer important patient-centered, comparative effectiveness research questions and demonstrate PCORnet capabilities, each initiative is also uniquely designed to test key aspects of PCORnet functionality.

Demonstration Study Initiatives

Interventional Studies

This initiative is comprised of the ADAPTABLE aspirin study, PCORnet’s first pragmatic, randomized, controlled clinical trial. ADAPTABLE is integrated with routine clinical care and health care delivery.  It is designed to test the ability to ascertain patients aided by electronic health records (EHRs); work with centralized IRBs and electronic informed consent; and patient recruitment.

Associated Studies

ADAPTABLE (Aspirin Dosing: A Patient-centric Trial Assessing Benefits and Long-Term Effectiveness)

Obesity Observational Studies

These studies employ an observational design and test the technical and operational aspects of PCORnet’s Distributed Research Network (DRN) in addition to standardized capture of a wide range of claims, EHR, and prescription data in the Common Data Model (CDM).

Associated Studies

PCORnet Bariatric Study

PCORnet Obesity Observational Study: Short- and Long-term Effects of Antibiotics on Childhood Growth

Patient-Powered Research Network (PPRN) Studies

The PPRN Studies are designed to test the ability to conduct research that addresses the concerns of patient network members via patient-identified research questions that have been prioritized by PPRN community stakeholders and participants. PPRN studies include both observational and randomized controlled trials.
