Longitudinal analysis of pain and illicit drug use behaviors in outpatients on methadone maintenance.

ABSTRACT:

Background

Little is known about the experience of chronic pain and the occurrence of illicit drug use behaviors in the population enrolled in methadone maintenance treatment (MMT) programs.

Methods

This is a secondary analysis of longitudinal data from two MMT samples enrolled in a randomized controlled trial of hepatitis care coordination. Patients completed pain, illicit drug use, and other questionnaires at baseline and 3, 9, and 12 months later. Associations were sought over time between the presence or absence of clinically significant pain (average daily pain ≥ 4 or mean pain interference ≥ 4 during the past week) and current illicit drug use (i.e., non-therapeutic opioid, cocaine or amphetamine use identified from self-report or urine drug screening).
