Assessment of the Effectiveness of Matrix Model Among Methadone Patients Using ATS in Ho Chi Minh City, Vietnam
This study assessed the effectiveness of the application of the Matrix model in patients undergoing methadone treatment for Amphetamine-type substance (ATS) in Ho Chi Minh City. A total of 951 methadone patients were screened; 60 (16%) met the inclusion criteria and of those 51 (85%) completed 16 weeks of study procedures. Most of the participants were ATS users with moderate or higher risk of dependence. Compared to the non-intervention group, the intervention group showed a significant reduction in positive urine tests for methamphetamine (a decrease from 100% to 11% vs. a decrease from 100% to 98% for the non-intervention group, p<0.001) and for opiates (a decrease from 36.7% to 3.7% vs. a decrease from 43.3% to 29.2% for the non-intervention group). In the intervention group, the quality of life increased from 76.74 points to 85.5, the proportion of depression decreased from 43.3% to 18.5%, anxiety decreased from 30% to 11.1%, and stress decreased from 76.7% to 29.6%. In the non-intervention group, quality of life decreased from 75.2 points to 74.5 points, the proportion of depression decreased slightly from 40% to 36%, anxiety decreased from 33.3% to 24%, and stress decreased from 76.7% to 76.0%. The intervention group was significantly more likely to adhere to methadone treatment (p<0.001). The proportions of participants in the intervention group and non-intervention group who discontinued treatment were 10% and 20%, respectively. The study results suggested that the MATRIX model could help reduce ATS and opiate use and improve mental health as well as treatment adherence.
