Normalizing and Mapping ADT Data / Normalizing and Mapping Workflow |
CTS allows you to normalize ADT data by specifying regular expressions that search and replace patient location and patient ID values in the HL7 feed so they are suitable for your Vocera system. A regular expression is a string that is used to find and manipulate text.
If you are unfamiliar with regular expressions, Vocera recommends that you brush up on them before tackling the task of normalizing patient locations and patient IDs. Here are just a few books that will help you learn how to use regular expressions:
There are also several regular expression tutorials and cheat sheets that you can find online.
Why would you need to normalize patient location values? For two reasons:
To normalize patient location and patient ID values, CTS requires that you create XML files with the following names in the \vocera\vcts\resources folder:
XML file | Description |
---|---|
apl.xml | Active (current) patient location |
ppl.xml | Prior patient location |
pid.xml | Patient ID |
Here's a sample normalizer file for the active patient location (apl.xml):
<normalizer> <entry> <format>$1 Room $2 : Saint Joseph</format> <node> <input>/PV1-3-1</input> <pattern>SJ ([0-9]+ North).*</pattern> <variables>$*,$1</variables> <node> <input>/PV1-3-2</input> <pattern>^.*([0-9]{2})$</pattern> <variables>$*,$2</variables> <node> <input>$2</input> <pattern>0*([0-9]+)</pattern> <variables>$*,$2</variables> </node> </node> </node> <node> <input>/PV1-3-1</input> <pattern>SJ (ICU).*</pattern> <variables>$*,$1</variables> <node> <input>/PV1-3-2</input> <pattern>CC([0-9]+)</pattern> <variables>$*,$2</variables> <node> <input>$2</input> <pattern>0*([0-9]+)</pattern> <variables>$*,$2</variables> </node> </node> </node> </entry> </normalizer>
