"In terms of unit costs (per person per day) across treatment modalities, there are clear differences between the treatment types. The highest unit costs are reported for inpatient modalities. The unit cost of inpatient psychosocial treatment is estimated to range from EUR 59 to EUR 404 per patient per day, with Sweden reporting the highest unit cost for this treatment. Detoxification carried out in inpatient settings is reported to cost between EUR 110 and EUR 303, with both the highest and the lowest estimates referring to treatment centres in the United Kingdom. Oral substitution treatment with methadone is reported to cost the least of the other treatment modalities, its unit cost ranging EUR 2 to about EUR 37 per patient per day, with the highest cost estimated in Norway. Although the unit costs of opioid substitution treatment are lower than those of the three other treatment modalities, due to the widespread use of this modality, the overall annual expenditure of reporting countries on opioid substitution treatment is higher than their annual expenditure for other treatment types."
