High-dose methadone (over 80 mg/day), older age, stable relationships, and avoiding alcohol improve retention in methadone maintenance programs for opioid dependence. These factors predict long-term treatment success.

Area of Science:

  • Addiction Medicine
  • Pharmacology
  • Public Health

Background:

  • Opioid dependence is a chronic relapsing condition requiring long-term management.
  • Methadone maintenance treatment (MMT) is a cornerstone of opioid use disorder pharmacotherapy.
  • Patient retention in MMT is crucial for treatment efficacy and reducing associated harms.

Purpose of the Study:

  • To identify factors influencing patient retention in a low-threshold methadone maintenance program.
  • To assess the impact of demographic, clinical, and substance use variables on long-term MMT engagement.

Main Methods:

  • A consecutive cohort of 370 opioid-dependent patients in an MMT program was analyzed.
  • Data on age, sex, social situation, substance use, and methadone dosage were collected.

  • Retention rates at 2 years were calculated and correlated with various predictive variables.

    • Main Results:

    • The overall 2-year retention rate in the MMT program was 72%.
    • Significant predictors of higher retention included methadone dosage > 80 mg/day, age > 30 years, living with family or a partner, and non-current alcohol use.
    • Variables like sex, employment status, length of heroin use, and HIV status did not show significant predictive value for retention.

    Conclusions:

    • Optimizing methadone dosage and addressing psychosocial factors like stable relationships and reduced alcohol consumption are key to improving MMT retention.
    • These findings can inform clinical practice to enhance long-term treatment engagement for individuals with opioid dependence.
