Viedoc offers support for adding reference data that will be automatically populated to specific forms. When reference data are configured for your study, it is not necessary to fill in reference values for each subject in each form separately.
It is possible to configure different sets of reference data that will be populated to the form based on:
factors that can affect the reference data, such as age or gender
reference data source, such as a lab
site
date
Terminology
Term
Definition
Reference data source
An institute that provides reference data, for example a lab.
Reference data scope
A mapping of the items that should be automatically populated with reference values, and the factors that they should depend on. One or more reference data scopes can be configured in Viedoc Designer > Global Settings, as set(s) of variables and factors (see definitions below).
Factor
A parameter that affects the reference data, for example a subject’s sex. Factors may affect the normal range for a test result.
Variable
A specific measurement to be carried out.
Date factor
The date the sample was collected or the measurement carried out. This field determines on which date the reference data to be populated are based, for example when the event date is not the same as the collection or measurement date.
Target type
An item of a certain type of information that a reference data source can provide for a specific variable (such as range, unit, low/high values, etc.). Any number of target types can be defined by the user.
Workflow
Reference data are configured in Viedoc Designer, Viedoc Admin and Viedoc Clinic. The schematic below depicts what different steps need to be taken, and which roles have permission to perform these steps.
