Abstract
Introduction and Aims. Specialist services have increased their capacity considerably in recent years to initiate and/or provide ongoing treatment for drug misuse. Consequently, methadone prescribing has substantially increased and over 17000 patients are currently receiving methadone. Clinical guidance promotes consumption on the premises (COP) initially to ensure patients take medication as prescribed and also to prevent diversion. Diversion poses two risks: the patient may remain under-treated and continue illicit heroin use; diverted drugs put others at risk. However, COP can be restrictive. Current UK guidance is vague and not evidence-based recommending 'around three months subject to assessment of compliance and individual circumstances'. The overall aim of this study was to describe clinical practice regarding prescribing methadone under COP in Scotland, and reasons for this. Design and Methods. A structured, postal questionnaire was sent to all lead clinicians in specialist drug treatment centres in Scotland in 2009 (n=42). The questionnaire explored current practice, influence of supervision on retention, views of best practice and contingency management. Results. The response rate was 76% (n=32). Clinicians usually supervise for a minimum of three months with patient-centred criteria used to determine when to reduce or stop COP. Employment, clinical stability, family support and concerns for the safety of children in the home influenced decision making. Contingency management approaches to supervision were widely used (62%). Discussion and Conclusion. In Scotland, clinicians' practice is variable and individualised to patients, but generally cautious regarding relaxing supervision conditions. This may reflect the lack of evidence-based guidance.
