Study summary

The purpose of this study is to determine if buprenorphine or methadone is better for the treatment of chronic pain among patients who have become addicted to prescription narcotics.

Read the detailed description

The purpose of this randomized clinical trial is to compare methadone with buprenorphine for the treatment of chronic pain among patients who have developed a physical dependence on prescription opiate analgesics that is associated with psychosocial dysfunction (i.e., addiction).

What researchers measure

Primary outcomes

  1. Number of Participants Retained in Treatment

    This outcome assesses the number of participants who completed the treatment after 6 months.

    Time frame: 6 months

Secondary outcomes

  1. Numerical Rating Score for Pain

    Pain was measured using a 0-10 point numerical rating scale (NRS) with 0 representing no pain and 10 representing worst pain possible.

    Time frame: 6 months

  2. Numerical Rating Score for Functioning

    We assessed functioning measured on a 0-10 point numerical rating scale (NRS)with 0 being the least amount of functioning and 10 the best amount of functioning.

    Time frame: 6 months

  3. Self-reported Illicit Opioid Use

    Time frame: 6 months
