Adult substance misuse services
Substance misuse is the continued use of drugs or alcohol despite negative consequences to the individual using the substance, and their friends, family and the community. All substance misuse has potential health, social and criminal consequences.
For full methodology of data collection, please see Public Health England: Drugs and alcohol - official statistics.
In 2009-10 the National Drug Treatment Monitoring System discharge codes and their definitions were revised. This was done to enable greater accuracy of measurement and to improve the consistency of the way in which clinical services code discharges.
Changes included a tightening of the way in which ‘treatment completed’ is recorded. Revised codes and definitions now distinguish between clients that are entirely drug free at the time of discharge, and those that are abstinent from the problem drug for which they sought treatment. And new codes distinguish between clients that are ‘referred on’ to treatment within either a community or prison setting. Because of this issue, the ability to directly compare 2009-10 and 2010-11 data to previous years is affected.
For alcohol treatment, when 'other' is referenced as an exit reason, this includes: transferred – not in custody; transferred – in custody; referred on (old code); treatment withdrawn/breach of contract; moved away; prison; died; other; not known; no appropriate treatment; and patient refused treatment.
Percentages may not add up to exactly 100% due to rounding at source.
Adults are defined as over 18 years of age.
