1 Introdution
1 Telix Implementation Guide
Welcome to the Telix Implementation Guide: Evidence of health treatments efficacy!
The Telix Implementation Guide defines profiles and value sets for representing the efficacy of health treatments. This guide is intended for developers of systems using FHIR who need to exchange information about treatment efficacy, as well as for authors of more specialized implementation guides within the healthcare domain.
This implementation guide covers the standardized representation of treatment efficacy, specifically how to convey the efficacy of a specific treatment for a specific condition. The content includes the classification of efficacy using the categories of benefits obtained with the treatments. The use of categories of benefits/outcome measures instead of specific outcome measures (as reduction in the scale of pain, or biomarkers) allows to process and compare data from researches that use different outcome measures.
Efficacy category outcomes include: (1) cure, (2) remission, (3) control, (4) elimination of symptoms, (5) reduction of symptoms, and (6) prevention. The guide also includes information about the total number of participants in the study, the scientific article or research from which the data was derived, and the country where the study was conducted.
1 To Learn about FHIR
This implementation guide is based on the Continuous Integration Build of the HL7 FHIR standard. It uses terminology, notations and design principles that are specific to FHIR. Before reading this implementation guide, it's important to be familiar with some of the basic principles of FHIR as well as general guidance on how to read FHIR specifications.
Readers who are unfamiliar with FHIR are encouraged to review the following R5-based links prior to reading the rest of this implementation guide.
