Purpose: Poorly controlled pain is common in advanced cancer. The objective of this article was to synthesize the evidence on the effectiveness of pain-focused interventions in this population. Methods: We searched MEDLINE, CINAHL, PsycINFO, Cochrane, and DARE from 2000 through December 2011. We included prospective, controlled health care intervention studies in advanced cancer populations, focusing on pain. Results: Nineteen studies met the inclusion criteria; most focused on nurse-led patient-centered interventions. In all, 9 (47%) of the 19 studies found a significant effect on pain. The most common intervention type was patient/caregiver education, in 17 (89%) of 19 studies, 7 of which demonstrated a significant decrease in pain. Conclusions: We found moderate strength of evidence that pain in advanced cancer can be improved using health care interventions, particularly nurse-led patient-centered interventions.
