Variation between and within drug treatment modalities: data from the National Treatment Outcome Research Study (UK)

This paper describes treatment practices in 54 drug treatment programmes taking part in the National Treatment Outcome Research Study (NTORS). Programmes were representative of the 4 main treatment modalities in the UK: in-patient, residential rehabilitation, methadone maintenance and methadone reduction. Distinguishing features of these forms of treatment were identified. Substantial variations in treatment practices were also observed within each modality, particularly for detoxification and prescribing arrangements, counselling and non-drug treatment services, and planned duration of treatment. Many programmes reported extensive waiting lists. These findings are discussed in the context of the growing international evidence of the association between patient outcome and the manner in which programme services are delivered.
