Summary of Changes

2020-0711-1513

2.0

  • This measure was re-evaluated to fit the definition of a clinical classification measure. The domain was changed from the QS to RS domain.
  • The RSEVAL assumption and variable was removed from this supplement, since it is not captured on the CRF and no assumptions are made on the potential values.
  • The example replaced the RSBLFL variable with RSLOBXFL.
  • Updated assumption 4 on the handling of results for RSTESTCD = "KFSS108" and "KFSS108A" and updated the example accordingly.
  • Updated the example description for clarity and included the representation that at visit 2, the instrument was not conducted.
