  • Measure patient progress during and after treatment to monitor change
  • Provide outcomes measurement for treatment programmes and providers through aggregated patient information

  • The Global Severity Index (GSI) is designed to help quantify a patient's severity-of-illness and provides a single composite score for measuring the outcome of a treatment program based on reducing symptom severity.
