This OST service self-assessment tool is designed to support local UK drug treatment providers and commissioners. It will help them provide the best possible treatment for and with their OST service users. 

The tool includes:

• guidance on how to complete the self-assessment
• sections on assessing current OST-specific practice, as well as broader issues for treatment services
• good-practice pointers and examples of evidence in a range of areas
• relevant best-practice guidance and research 

This tool is part of Public Health England’s OST good practice programme. The programme has also developed other OST good practice resources including:

• the Best practice in Optimising Opioid Substitution Treatment (BOOST) e-learning programme, which includes short films showing typical clinical conversations between people who are on OST and their drug treatment and recovery workers
• an OST guide for drug treatment and recovery workers to provide the information they need to deliver good quality OST to service users
