For a given product, the persistence rate represents the follow-up of the temporal distribution of the insured persons present at the first study period, which represent the base 100.
The rate persistence is a quantitative indicator of longitudinal monitoring.

Example

For 100 insured persons having received at least one dispensation of a product in 2015:

  • 71 social policyholders in 2015 received at least one new dispensation of the product in 2016. 29 social policyholders did not receive a new dispensation in 2015.
  • 59 people insured, who had already received at least one dispensation of the product in 2015 and 2016, received at least one new dispensation of the product in 2017.
  • 51 social policyholders, who had already received at least one dispensation of the product in 2015, 2016 and 2017, received at least one new dispensation of the product in 2018.

The product persistence rate is 71% of social policyholders in 2017, 59% in 2017 and 51% in 2018.

Terminology

The persistence rate can be translated into English as Persistancy Rate.
