Evidence Variable
The Evidence Variable resource describes a “PICO” element that knowledge (evidence, assertion, recommendation) is about. PICO stands for population, intervention, comparison and outcome.

Description
The scope of the EvidenceVariable resource is to describe a “PICO” element that knowledge (evidence, assertion, recommendation) is about. PICO stands for:
– Population – the population within which exposures and outcomes are being considered
– Intervention – the conditional state or exposure state being described for which one is expressing the risk of or effect on an outcome
– Comparison – the alternative conditional state or alternative exposure state when one is comparing states for the effect on an outcome
– Outcome – the result or effect of an intervention or exposure in a population.
PICO (and its variants like PECO or PICOT) is a universal acronym used in evidence-based medicine communities to clearly express research questions and evidence findings. The Evidence Variable resource allows expression of the components of a PICO question in codeable and reusable formats.
Multiple resources describing evidence findings (Evidence, Effect Evidence Synthesis, Effect Evidence Bit, Risk Evidence Synthesis, Risk Evidence Bit) will reference Evidence Variable to describe what the evidence findings are about.
Fast Healthcare Interoperability Resources (FHIR) is a draft standard describing data formats and elements (known as “resources”) and an application programming interface (API) for exchanging electronic health records. The standard was created by the Health Level Seven International (HL7) health-care standards organization.
Its goal is to facilitate interoperation between legacy healthcare systems, to make it easy to provide healthcare information to healthcare providers and individuals on a wide variety of devices from computers to tablets to cell phones, and to allow third-party application developers to provide medical applications which can be easily integrated into existing systems.
FHIR provides an alternative to document-centric approaches by directly exposing discrete data elements as services. For example, basic elements of healthcare like patients, admissions, diagnostic reports and medications can each be retrieved and manipulated via their own resource URLs (Uniform Resource Locators). FHIR was supported at an American Medical Informatics Association meeting by many EHR (Electronic Health Record) vendors which value its open and extensible nature.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Concept_Name | Name of the concept in the FHIR structure | string | required : 1 |
Computer_Ready_Name | A Computer-ready name (e.g. a token) that identifies the structure - suitable for code generation. Note that this name (and other names relevant for code generation, including element & slice names, codes etc) may collide with reserved words in the relevant target language, and code generators will need to handle this. | string | - |
Type | The type the structure describes. | string | - |
Dollar_Ref | The Dollar_Ref ($ref) string value contains a Uniform Resource Identifier (URI) which identifies the location of the JSON (JavaScript Object Notation) value being referenced. | string | - |
Description | A free text natural language description of the structure and its use | string | - |
Items | The value of the keyword should be an object or an array of objects. If the keyword value is an object, then for the data array to be valid each item of the array should be valid according to the schema in this value. | string | - |
Enum | The enum is used to restrict a value to a fixed set of values. It must be an array with at least one element, where each element is unique. | string | - |
Required | The value of the keyword should be an array of unique strings. The data object to be valid should contain all properties with names equal to the elements in the keyword value. | string | - |
Const | The value of this keyword can be anything. The data is valid if it is deeply equal to the value of the keyword. | string | - |
