Multicenter Study Clinical Trial
Defining patient-centered, multidimensional success criteria for treatment of chronic spine pain.
This study aimed to define patient-determined success criteria for treatment of chronic spine pain across four domains: pain, fatigue, emotional distress, and interference with daily activities. ⋯ Future research should validate these success criteria, particularly for the less studied domains of fatigue, distress, and interference, and investigate how these criteria evolve over the course of different treatments.

Multicenter Study Clinical Trial
Cluster analysis of the pain outcomes questionnaire.
The purpose of this study was to derive and describe subtypes of Pain Outcomes Questionnaire (POQ) profiles produced by a large, heterogeneous multisite sample of chronic pain patients (N = 672). ⋯ The results of this study are generally consistent with those of previous cluster analytic investigations of pain patients and suggest that psychosocial/behavioral classification systems may serve a useful heuristic function in the assessment and treatment of chronic pain that is not provided by current diagnostic taxonomies.

Multicenter Study Clinical Trial
Titration with oxymorphone extended release to achieve effective long-term pain relief and improve tolerability in opioid-naive patients with moderate to severe pain.
Assess the effectiveness and tolerability of a program of gradual dose titration with oxymorphone extended release (ER) for treatment of moderate to severe chronic pain in opioid-naive patients. ⋯ Oxymorphone ER provided effective pain relief from moderate to severe chronic pain in opioid-naive patients. Gradual titration was well tolerated, with a low rate of discontinuations caused by AEs.
