Brief project description
SCOPE
European drug policies and action plans require sound and comprehensive evidence on what are the main issues in the drug problematic and how to intervene. In order to obtain a better understanding of the different aspects of the drug phenomenon as well as the impact of related measures, the information exchange, data collection and monitoring of the drug situation at the European level are of great importance.
A comprehensive understanding of the extent of the drug use problem requires a review of several indicators:
- the magnitude of drug use measured by prevalence in the general population,
- the potential of problem drug use as measured by drug use among young people,
- drug-related morbidity and mortality and costs and
- consequences of drug use measured by treatment demand.
TREATMENT DEMAND INDICATOR (TDI)
Effective prevention of health problems and other consequences of substance use requires information on the characteristics and patterns of use, as well as data on associated problems. When people with substance use disorders come into contact with health professionals, the data collected is an essential source of information for epidemiology. To this end, the Treatment Demand Indicator (TDI) has been adopted and standardised as an epidemiological indicator in the European Union on behalf of the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA).
OBJECTIVE
The objective of the Treatment Demand Indicator is to collect information in a harmonised and comparable way across all Member States on the number and profile of people entering drug treatment (clients) during each calendar year. Although the name of the indicator is the ‘Treatment Demand Indicator’, it collects information on people entering treatment. TDI is widely recognised as the instrument for collecting and reporting data on people entering treatment for their drug use inside and outside Europe, as an indirect indicator of the unobserved level of people that are potentially in need of drug treatment.
The primary purpose of the information collected by the TDI indicator is :
- to gain insights into the characteristics, risk behaviours and drug use patterns of people with drug problems entering treatment;
- to help to estimate trends in the extent and patterns of problem drug use, ideally in combination with other drug indicators;
- to calculate prevalence and incidence rates of addiction treatment using indirect methods alongside with other datasets;
- to set up more specific studies by linking this register using the same identifier to other national registries using the same identifier (mortality register, health insurance database).
EUROPEAN AND NATIONAL APPROACH
A common European data collection protocol has been developed and improved over time. Since 2000, the EMCDDA has set up a system of data reporting by the EU Member States and adopted various formal agreements with them in order to stimulate and facilitate the collection and reporting of data from the national to the European level. Currently, the indicator collects data from 30 countries (28 EU Member States, Norway and Turkey) and provides information on almost 500,000 patients per year.
Belgium started standardised data collection for TDI in 2011, when health ministers decided to set up a coordinated registration of treatment requests. Prior to this, several initiatives to gather information at different levels (region, city, groups of centres) on treatment requests for substance use problems had already taken place in Flanders, Brussels and Wallonia. But in order to provide a coherent national view of the phenomenon, it was decided to work on the basis of a national protocol.
Sciensano was appointed as the coordinator of the Belgian TDI register and charged with developing flexible and secure technical tools to facilitate the registration of data in accordance with national privacy rules. Since the 2015 registration year, the Belgian protocol has been updated to include the changes of the third European protocol.
The BTDIR data collection

The BTDIR Data Collection DefinitionThe survey has been created by the service Lifestyle and chronic diseases and provided to healthdata.be for integration within the web interface. For more information, you can consult the below documentation:
For any question in regards the content of the survey, you can contact the Sciensano researchers at the following address: TDI@sciensano.be
BTDIR User Manual
BTDIR User ManualData Providers have the possibility to send TDI data to Sciensano in 2 ways:
METHOD 1: Manually via a simple web interface
This system is designed for centers that
- do not have their own system for recording patient data, or
- are unable to adapt their system to the requirements of the TDI system
Access the web interface by entering the following URL in any internet browser: https://lime.healthdata.be.
You will be redirected to the government's Federal Authentication Service (FAS), where you can log in with multiple digital keys with eID or digital identity.

If you choose to connect via itsme, you will need to enter your cell phone number.

Follow the instructions on your mobile device via the itsme application.

To complete the itsme login procedure, you need to select the green confirmation button (available in FR and NL) in the screen below to access the Sciensano environment.
| NL | FR |
![]() | ![]() |
Select the green confirmation button ("Profiel bevestigen" or "Confirmer le profil") to log in.
You will land on the LimeSurvey page where you need to select the desired survey.

You will be asked to enter a token in order to open the survey. If you haven't received the token or have forgotten it, please email TDI@sciensano.be for assistance.
Select the language in which you want to complete the survey and click on Next (Continuer / Ga verder).

The survey appears on your screen (see image further below). Complete the survey by selecting the applicable answers.

Unlike before, you must provide the name of your centre/hospital at the start of the registration.
Tip 1: You can type the first few letters of the name to find it more easily in the list.
Tip 2: If your centre is not in the list, you can add a new centre by selecting the "other" option and typing in the name.
Depending on the centre of your choice you will see:
- the questions corresponding to your type of centre (some questions are only asked of certain types of centre)
- if necessary, the corresponding treatment units we have available.
Tip: You can also always add additional units not mentioned via the "other" option.
Checks are made on the data in the form
- the national register number: enter numbers only. No hyphens (-), dots (.) or spaces. A modulo 97 check is performed to ensure that the number is correct.
Tip: If the national register number cannot be validated, you can always select the "No identifier" option.
- ages: the age of first use cannot be greater than the current age, and the age cannot be negative or greater than 100.
When you need to interrupt completing the survey, you can finish it later (1). Retrieve it at a point of time that suits you (2).

When the survey is completed and you are satisfied with the answers, you can send it by clicking on the Send button (Envoyer / Verzenden).

Your form has been correctly sent if you receive the following message. You can continue registering by clicking on the link provided.

Please note! If you do not receive this message and return directly to the start-up screen, your form has not been sent.
Tip: Don't remain inactive for too long on a survey you've started, as you risk being disconnected and losing the data you've already entered.
METHOD 2: By batch, via the deposit module.
The deposit module is a secure e-mail box, in the form of a standardised annual data file.
This system is intended for centres that have a patient registration system that is fully adapted to the requirements of the TDI system. The centre is then responsible for ensuring that the registration system is compliant and operational, as well as for all aspects of the TDI system.
For any question regarding method 2, you can contact the Sciensano researchers at the following address: TDI@sciensano.be
The BTDIR data transfer
The BTDIR data transferThe solution put in place to collect data via Method 1 consists in a simple web interface in the healthdata demilitarized zone (DMZ) environment. As soon as data are submitted (fire-and-forget approach), they are sent through eHealth (for pseudonymized using the TDI key) to the Sciensano eHbox.

Email security policy
Email security policyWHAT IS THE PROBLEM?
Sciensano blocks e-mails from organizations if the configuration of their e-mail and/or DNS services allow potential abuse by spammers/attackers. More specifically, if the configuration enables other senders to impersonate your organization by allowing them to mimic your organization’s e-mail “Header From”.
In other words, they can send phishing and spam mails that cannot be distinguished from genuine mails from your organization.
If you’re responsible for managing your ICT infrastructure, keep reading. If not, pass this message on to your ICT department or to the ICT service that’s managing your ICT infrastructure.
HOW TO SOLVE IT?
You’ll have to verify that your configuration complies with “Sender Alignment” security requirements.
More specifically, your mail services and DNS will have to be configured according to ICT standards.
These configurations are common, well-documented and supported by hosting companies. Some useful links:
- https://dmarcian.com/alignment/
- https://mxtoolbox.com/dmarc/spf/spf-alignment
- https://o365info.com/how-does-sender-verification-work-how-we-identify-spoof-mail-the-fiveheros-spf-dkim-dmarc-exchange-and-exchange-online-protection-part-9-of-9/
We’ve noticed that this issue frequently occurs in organizations which moved their ICT infrastructure to cloud services such as Microsoft (O365), Amazon, Google, and MS Azure without properly configuring the ICT infrastructure which is not managed by these providers.
The configurations and recommendations need to be implemented on the customer’s ICT infrastructure, either internally or externally. DNS and Mail services are the main ICT platforms for these actions.
THE USE OF DIFFERENT DOMAINS IN THE MAIL SENDING PROCESS
E-mails contain an “Envelope From” and a “Header From”. Both need to match to avoid that the mail is blocked.
Some examples:
- A public service is using its new domain name in the “Header From” and its old domain name in the “Envelope From”.
- Envelope From = noreply@publicservice.fgov.be
- Header From = noreply@publicservice.belgium.be
➔ These e-mails will be blocked.
Remark: Because it’s a noreply address, the sender will not even be aware of us rejecting the e-mail …
2. An organization is using a cloud service (Freshservice) for its helpdesk tool and the “Envelope From” has not been customised.
• EnvelopeFrom = bounces+us.3.52773-helpdesk=organisation.be@emailus.freshservice.com
• Header From = helpdesk@organisation.be
➔ These e-mails will be blocked.
3. A company uses a cloud service (Amazon SES) to send the delivery notification and the “Envelope From” has not been customized.
- Envelope From = 01020188573f374-96de6437-9134-45f4-8aa6-3e9ac18d5848-000000@euwest-1.amazonses.com
- Header From = noreply@company.be
➔ These e-mails will be blocked.
