Careset Mapping Tables

There is a lot of overlap between the different Caresets, but also between the Caresets and Carepaths. Caresets build upon the basic semantic foundation of Carepaths, intentionally re-using the SNOMED CT and LOINC codes defined for standalone parameters (for example, Heart Rate or Body Weight as seen in the Carepaths). However, because Caresets also track Encounters, advanced Questionnaires, and procedural outcomes, they expand upon that core set. We list here the expanded mappings used in the Caresets and their connection to the base Carepath parameters.

General mappings

If there is a distinction between OPAT and ONCO (Antitumoral therapy) this is noted in the table. It might be that in the future we can align these caresets even more. The yellow marked codes are codes that do not appear in the corresponding carepath in this IG.

Note on parameters with units

Parameters with a unit (such as temperature, weight, etc.) are being exchanged as valueDecimal (so simply a number without a unit). The unit is in the question (Questionnaire).

This was not noticed until enrolling the POC because the examples from hl7 also include the unit in the questionnaire and then do not repeat it in the questionnaire response, e.g. birthWeight https://hl7.org/fhir/R4/questionnaireresponse-example-bluebook.json.html

It would be reasonable to consider using valueQuantity instead in the future.

Note on cathetermapping for OPAT

For OPAT questionnaires, we also want to include the catheter type in a structured manner. This led us to the following mapping:

Catheter Description SNOMED Mapping
Port catheter 52124006 | Central venous catheter, device (physical object) |
Tunneled catheter with 1 lumen 1396546006 | Single lumen tunneled central venous catheter (physical object) |
Tunneled catheter with 2 lumen 1396570005 | Double lumen tunneled central venous catheter (physical object) |
Tunneled catheter with 3 lumen 1396538005 | Triple lumen tunneled central venous catheter (physical object) |
Single lumen Midline 1396531004 | Single lumen midline catheter (physical object) |
Double lumen Midline 1396527005 | Double lumen midline catheter (physical object) |
Single lumen PICC 1396526001 | Single lumen peripherally inserted central venous catheter (physical object) |
Double lumen PICC 1396489007 | Double lumen peripherally inserted central venous catheter (physical object) |
Peripheral catheter 423954007 | Peripheral catheter (physical object) |

In the background, this segment will look as follows:
