Facing the Growing Heroin Problem in Colombia: The New Methadone-assisted Treatment Programs.

OBJECTIVE

Colombia is facing a rising epidemic of intravenous heroin use. Knowledge of the methadone-assisted treatment programs in the country is crucial in order to propose improvement strategies.

METHODS

13 programmes from priority regions were surveyed. The demographic and clinical characteristics of the patients attending the programs, a description of the services offered, their methadone treatment protocols, the various barriers to treatment and the causes of treatment abandonment were reviewed.

RESULTS

12/13 questionnaires were analysed with a total of 538 active patients. Most of the patients attending these programs were men (85.5%) between 18 and 34 years-old (70%). Forty percent (40%) were intravenous drug users and 25% admitted sharing needles. The comorbidities associated with heroin use were mental illness (48%), hepatitis C (8.7%) and HIV (2%). Psychiatric comorbidity was more likely in patients attending the private sector (69.8% vs 29.7%; p<0.03). The initial average dose of methadone administered was 25.3±8.9mg/day, with a maintenance dose ranging from 41 to 80mg/day. Lack of alignment with primary care was perceived to be the most serious barrier to access, ahead of problems with insurance and prejudice towards treatment with methadone (p<0.05). Health Administration and insurance problems (p<0.003), together with the lack of availability of methadone (p<0.018) and relapse (p<0.014) were the most important reasons for abandonment of treatment.

CONCLUSIONS

The treatment protocols of these programmes offer different levels of development and implementation. Some of the barriers to access and reasons for abandonment of treatment with methadone can be mitigated with better health administration.
