# Definition

Initiation is the first time a patient presents a prescription to the pharmacy.

The weight of initiation sales is the ratio of estimated extrapolated initiation sales to total sales (initiation + renewal).

This indicator is available in thePrescriptions Order Analysis.

# Calculation

Initially, the distribution weights in initiation are calculated on an observatory of non-extrapolated pharmacy sales.

In order to obtainSales volume andSales valueThese weights are multiplied by the national extrapolated sales to estimate the extrapolated sales in initiation.

These sales are used as the basis for calculating the initiation weights that will be displayed on The Hub.

# Specificity for non-prescription sales

Only prescription sales have initiation and renewal information on the sales receipt lines.

However, you have the possibility to take into account non-prescription sales in your studies, but due to lack of information on initiations and renewals for non-prescription tickets,all these non-prescription tickets are considered as initiations. The distribution weights between initiation and renewal will then take into account non-prescription sales in initiation.

However, you have the possibility to consider only prescription sales with theStandard prescription by choosing the modalitySales with prescription. The distribution weights between initiation and renewal will then be based on prescription sales only.

# Terminology

The weight of initiation sales can be translated into English asN Initiation Weight.

# Example

Let's consider a market with an estimated 7,000 boxes delivered over the period P in initiation and 3,000 boxes in renewal

N Initiation Weight =7.000 / ( 7.000 + 3.000 ) = 70 %

70% of volume sales are delivered in initiation.

# Declinations

It is possible to study this indicator in evolution:

• Compared to the same period last year :N Initiation Weight Delta

• Compared to the previous adjacent period :N Initiation Weight Trend

# Limitations

• Limitation on market size: maximum 1,000 products

• Applicable to human, veterinary and non-medical elective drugs

• PHARMA only
