SAVI - Sheffield Accelerated Value of Information


Mark Strong, Penny Breeze, Chloe Thomas and Alan Brennan.

What SAVI does

Using only PSA results from your model

In a matter of seconds from the SAVI online application you can generate:

  • Standardised assessment of uncertainty (C-E planes and CEACs)
  • Overall EVPI per patient, per jurisdiction per year and over your decision relevance horizon
  • Expected Value of Perfect Parameter Information (EVPPI) for single and groups of parameters

The online application is hosted at
