Statistics extraction

The application

When you apply for a statistics extraction, you must submit a project description and a data extraction description. Both documents are important for us to gain an overview of your project and the information you request.

We use the data extraction description to determine which statistical tables we need to generate for you. It is therefore important that you describe the requested tables as precisely as possible.

We prepare the final specification of your extraction based on your description and through an ongoing dialogue with you.

The form for instructions for extract description for statistics extraction and the form for instructions for project description are currently only available in Danish. 

Processing of your application

All time spent by Research Services on your application will be invoiced continuously at the applicable hourly rate.

First, an agreement will be prepared, which describes the data extraction in detail. Preparing the agreement means that Research Services will spend time reviewing your application and examining the data sources to determine whether data are available to support your needs.

As part of the initial processing, we will have an ongoing dialogue with you about the delimitation and structure of the data extraction.

Please note that part of the programming of your data extraction will take place during this initial review. This means that any change requests during the process will require reprogramming and therefore additional time – even if the changes involve simplification or reduction of the extraction.

Processing your application for a statistics extraction will often take longer than other applications handled by Research Services. This is because there is often a need for a more detailed clarification of which data and delimitations should form the basis of the statistical tables produced. It is therefore important that you are as thorough as possible in describing how the statistical tables should be generated in your project and extraction descriptions, as this may help shorten the processing time.

Discretionisation of data

All statistics extractions are discretionised.

As a general rule, Research Services will blur fields where fewer than five persons or observations are included. If we assess that tables may otherwise contain personally identifiable information, these will also be blurred.

Since a statistics extraction is discretionised and does not contain individual-level data, the results can be sent directly to your e-mail.

What can you apply for as a statistics extraction?

As a general rule, you can apply for simple descriptive statistics from all the health registers made available by Research Services.

Research Services will assess whether it is possible to produce a meaningful statistics extraction based on the requested data.

Examples of statistics extractions that Research Services can provide include:

• Statistical table of patients with specific diagnoses by year, gender, age group and treatment codes
• Statistical table of patients with specific procedure codes by region, diagnosis group, gender and age group
• Statistical table of over-the-counter and prescription-only medicine by product number, ATC code, total DDDs and total price
