Background: The undertreatment of cancer pain remains a significant clinical problem.

Objective: The aim of this randomized controlled trial was to evaluate the efficacy of the PRO-SELF Pain Control Program that was modified for Norwegian cancer patients in decreasing pain and increasing opioid intake compared with control care.

Interventions/Methods: Oncology outpatients with pain from bone metastasis were randomized into the PRO-SELF (n = 87) or control (n = 92) groups. A nurse visited patients in the PRO-SELF group in their home at weeks 1, 3, and 6 and conducted telephone interviews at weeks 2, 4, and 5. Patients in both groups completed a daily diary of pain intensity ratings and analgesic intake.

Results: For both groups, significant decreases in pain intensity scores and in hours per day in pain (both, P < .001) were found over the 6 weeks of the study. However, no significant group × time interactions were found for any of the pain measures. In both groups, total dose of opioid taken increased over time. However, no significant group × time interactions were found for changes over time in the total dose, around-the-clock dose, or as-needed dose of opioid analgesics taken.

Conclusions: Possible reasons for the lack of efficacy include an inadequate dose of the psychoeducational intervention, inadequate changes in analgesic prescriptions, and/or the impact of attention provided to the control group.

Implications for Practice: Coaching, nursing support, and the use of a pain diary may be important interventions to reduce pain intensity.
