Besides supporting national and international Terminology Standards, such as SNOMED CT, ICD-10, or LOINC, Snowray also supports the creation and maintenance of Custom Code Systems.
Below you can read about the features that apply to all Code Systems, while visiting a Code System subpage will reveal functionalities that are specific to the selected Code System.
Users have the option to access Code Systems either from the Dashboard or the Resources Page. When starting out from the Dashboard, clicking the resource card will automatically take users to the Overview tab of the Code System. In case of approaching from the Resources page, pressing the resource title will result in the same, while double-clicking the row will open the Content tab. Once on the Content tab, users have access to the Code System hierarchy and browsing of the terminology itself can immediately begin.
You can browse different versions of a Code System, if you click on the version tag indicated in the top-right corner of the resource's page and select an earlier version from the dropdown.
Clicking the small triangles next to the parent concepts enables users to search for concepts by expanding the tree. Besides this aforementioned manual approach, another option offers to use the filter search for lexical matches.
Search results can be examined in a list or a tree view.
By default, matching results are displayed in a flat list.
In addition to the filter search, Snowray also provides an advanced search option for certain Code Systems (SNOMED CT and Custom Code Systems).
When browsing a Code System, selecting a concept navigates users to the concept details. On the concept's Overview tab descriptions, properties, and metadata are revealed. Some of the content is displayed in blue color, which indicates that it is a link to another concept. Clicking on those links navigates users to the linked concept's detailed overview.
Concepts are read-only components and can be browsed only within a Code System.
The concept's History tab displays the changes made to the selected concept. Each change is represented on a timeline and has an individual node. In their title, the nodes display the name of the user who did the modification and the elapsed time since the change, while the action that modified the concept can be found in the details part.
To switch between the views, click on the icon, and select the corresponding option from the menu.
