Treatment demand indicator (TDI)
Summary
The treatment demand indicator (TDI) is one of five key epidemiological indicators which contribute to the overall EMCDDA aim of providing objective, reliable and comparable information at a European level concerning drugs, drug addiction and their consequences (EU action plan on drugs 2000–04). This information is intended to provide the Community and Member States with, ‘a better understanding of the drugs problem and the development of an optimal response to it through a measurable and sustainable improvement in the knowledge base and knowledge infrastructure’ (EU drugs strategy, 2005–12).
To achieve this objective, the Centre is required to collect, analyse, compare and disseminate information at EU level, to: ‘ensure improved comparability, objectivity and reliability of data by establishing indicators and common criteria of a non-binding nature, compliance with which may be recommended by the Centre, with a view to greater uniformity of the measurement methods used by the Member States and the Community’ EMCDDA/7/01.
More information on the TDI key indicator can be found in the 'TDI toolbox' on this page.
TDI toolbox
The TDI toolbox provides access to a range of TDI-related material developed by the EMCDDA over the years. New resources will be added as they arrive. It is intended mainly for researchers and experts in the field of epidemiology.
Key documents
TDI Protocol ver 3.0 - Treatment demand indicator standard protocol 3.0 (including technical annex)
This protocol is the most detailed description available of the methodology used by the key indicator and is principally aimed at professionals in the field.
Overview of the TDI key indicator (8 pages, PDF)
This document provides an overview of the treatment demand indicator. It is written in an easy to understand manner and is intended for a wider readership.
TDI statistical methods and definitions
Part of the EMCDDA Statistical bulletin, this text provides a summary of the methods and definitions used in TDI and is primarily intended to assist in the interpretation of data.
