Severity Stratifying

There are two key stratifying tools used by the latest RCOG guideline:

  1. Pregnancy-Unique Quantification of Emesis (PUQE)
  2. HyperEmesis Level Prediction (HELP)

PUQE can help define if NVP is mild, moderate or severe.

HELP score is more useful for tracking the trend of HG to monitor response to treatment.
