A systematic review of the effectiveness of patient-based educational interventions to improve cancer-related pain.

Despite existing guidelines to assess and manage pain, the management of cancer-related pain is often suboptimal with patients often being undertreated. Inadequate pain management may be due to patient-related barriers. Educating patients may decrease these barriers. However, the effect of pain education on patient-related outcomes is still unclear. This review aimed to study the effect of educational interventions on cancer-related pain.
