SMART on FHIR Conformant Infrastructure for Recording Patient Reported Outcomes
This software infrastructure allows patients to report their health outcomes through digital tools that securely connect to healthcare systems. It uses open standards so different systems can work together, and it's built entirely with open-source components so it can be freely used and adapted.
At a glance
Use when
Integrating patient-reported outcomes into clinical workflows using open standards and open-source tools, especially within FHIR-compliant EHRs
Avoid when
Working in legacy systems without FHIR API support or in low-digital-literacy patient populations
Inputs
Patient-reported outcome questionnaires, patient identity and consent via SMART on FHIR, FHIR-based EHR data
Outputs
Standardized FHIR-formatted PRO data stored in EHRs, patient access to their own PRO data
How it works
An open-source, SMART on FHIR conformant infrastructure enabling standardized collection and integration of patient-reported outcomes (PROs) into healthcare systems. It leverages FHIR resources and SMART on FHIR authorization framework to enable secure, interoperable PRO data exchange within electronic health record (EHR) ecosystems, supporting the H2O project’s goal of incorporating patient perspectives using open standards.
