The Prescriptor EVS makes use of several information sources to suggest an effective prescription:

The G-Standaard

Prescriptor makes use of the so-called G-Standaard by Z-Index. This is the pharmacological database that was previously known as the KNMP-taxe. The G-Standaard in Prescriptor is updated monthly. Prescriptor uses Table 25 for dosage and usage guidelines, as part of the G-Standaard. Z-Index publishes a new version of the G-Standaard each month (usually at the end of the month for the following month).

Update cycle in Prescriptor:

Monthly, at least 10 times per year.

Pharmacotherapeutic Compass

Prescriptor is linked (directly) to the product information of CVZ's pharmacotherapeutic compass (FTK). The link between the EVS, Z-Index and FTK is based on the drug's ATC code. This integration allows the Prescriptor user to switch to another medication through the compass and Z-Index. CVZ publishes a new version of the pharmacotherapeutic compass every year.

Update cycle in Prescriptor:

Yearly. The timing depends on when it is received.


There is the possibility to consult various formularieswithin Prescriptor while prescribing medication. Prescriptor comes with the NHG-EVS (and the pharmacotherapeutic compass). The Dutch association for general practitioners publishes an update of the NHG formulary twice a year, usually in June and December. The available additional formularies are:

  • ETAS
  • Formularium Nijmegen

An additional subscription is needed to gain access to these additional formularies. Subscriptions are available in our webshop.

Update cycle in Prescriptor:

  • NHG-EVS: 2x per year, in June and December, depending on the timing of receipt.
  • NHG documents (standards, patient letters and graphics): 2-4x per year.
  • ETAS formulary: 1-2x per year.
  • Nijmeegs formularium: is currently not being updated.


The International Classification of Primary Care (ICPC) is accepted as a standard for coding and classifying complaints, symptoms and disorders in general practices in the Netherlands. The ICPC is of an internationally accepted quality: chapters and sections. WONCA is responsible for its maintenance. In the Netherlands, general practitioners use ICPC-1. NHG publishes the Dutch translation of ICPC-1. NHG also maintains the so-called subsections. This offers further detail on a national level within the internationally established sections. Over the years, several versions of the subsections have been published. This is the reason why Prescriptor does not make use of the subsections, but instead shows the available indications under the relevant ICPC main code. Most HISs (GP information systems) are currently using ICPC-1 from 2009.


A subsequent version of ICPC - ICPC-2 - was already published in 1998. It not only differs from ICPC-1 in the relatively small changes in the main categories, but also in different interpretations for some categories. The benefit of ICPC-2 is that it is linked to the International Classification of Diseases version 10. (ICD-10).

Update cycle in Prescriptor:

Whenever a new version is available.
