An overview of the NEWS2 message design.

The high-level design of NEWS2 based on developing a number of INTEROPen CareConnect Level 2 and level 3 profiles as below:

Level 2 and Level3 profiles

The NEWS specification allows the sending of just the total NEWS2 score or the NEWS2 score with parameter values or the NEWS2 score, parameter values and their corresponding sub-scores.

These three options within the message design for NEWS2, depend on the data available in the source system. The linkages between resources for the three options are shown below.

1. Systems holding the NEWS2 score, sub-scores & observations

This is the recommended option to share NEWS2.

For systems that hold the NEWS2 score, the sub-scores and the associated observations:

  • the overall NEWS2 score is held in the NEWS2 profile
  • the NEWS2 sub-scores are held in NEWS2 sub-score profiles, contained within the NEWS2 profile. The NEWS2 profile links to each sub-score profile using the related link
  • the observations are referenced by the sub-score profiles using the related links

The linkages for systems that hold the NEWS2 score, sub-scores and observations looks like this: NEWS2 score, sub-scores and observations

The diagram below illustrates this with sample clinical data:

2. Systems holding the NEWS2 score & observations only

For systems that hold the NEWS2 score and the associated observations (but no sub-scores):

  • the overall NEWS2 score is held in the NEWS2 profile
  • the observations are referenced by the NEWS2 profile using the related links

The linkages for systems that hold the NEWS2 score and observations looks like this: NEWS2 score, sub-scores and observations

3. Systems holding just the NEWS 2 score

For systems that hold the NEWS2 score (but no sub-scores or associated observations):

  • the overall NEWS2 score is held in the NEWS2 profile
  • there are no related links

Systems that only hold the NEWS2 score will only send the NEWS2 profile: NEWS2 score, sub-scores and observations
