The following constraint types are used when creating routing constraints.
 | Note: A wildcard represents unknown or variable information. |
| Constraint type | Description |
|---|---|
| Older than | Route studies for patients who were born before a specified date; for example, to separate pediatric and non-pediatric patients. |
| Younger than | Route studies for patients who were born after a specified date; for example, to separate geriatric and non-geriatric patients. |
| Equal to | Route studies when the constraint value matches the
routing value exactly.
For example, if the constraint is 'Current Patient Location equal to ORTHO,' studies are routed only to locations that exactly match ORTHO. |
| Begins with | Route studies when the constraint value matches
the beginning of the routing value. Used to group similar constraint values,
or in place of wildcards.
For example, if the constraint is 'Current Patient Location begins with ORTHO,' studies are routed to locations ORTHO:ER, ORTHO:ICU, and so on. |
| Ends with | Route studies when the constraint value matches the
end of the routing value. Used to group similar constraint values, or in
place of wildcards.
For example, if the constraint is 'Current Patient Location ends with ER,' studies are routed to locations ORTHO:ER, TRAUMA:ER, and so on. |
| Contains | Route studies when the constraint value matches
any part of the routing value. Used to group similar constraint values,
or in place of wildcards.
For example, if the constraint is 'Current Patient Location contains ER,' studies are routed to locations ORTHO:ER, ER-PEDS, and so on. |
| Not Equal to | Route studies when the constraint value does not match
any part of the routing value.
Use to group similar constraint values, or in place of wildcards. For example, if the constraint is 'Current Patient Location not equal to ER,' studies are routed to locations PEDS, ICU, and so on. |
