In the eight systematic reviews included, two reported that educational interventions had a positive impact on pain intensity. The rest did not report any effects on pain outcomes but concluded improved knowledge and adherence to pain medications. A detailed review of randomized, controlled trials included in the systematic reviews reported improved pain intensity outcomes in 12 studies and no significant difference from controls in 18 studies. Educational interventions had at least one of the following components: education on the physiology of cancer-related pain, advice on how to report and communicate pain, enhancements of provider assessments of pain, improved analgesic prescribing, approaches to barriers to nonadherence, nonpharmacologic strategies, or the promotion of pain reassessment.
Educational interventions for healthcare providers improved knowledge and attitudes, but their effects on patient pain outcomes were not demonstrated. Education for patients has shown inconsistent effects on pain outcomes. The key characteristics of effective educational interventions were not clear. Educational interventions for patients improved their knowledge and self-reported pain outcomes.
Evidence regarding the effectiveness of educational and psychoeducational interventions to reduce cancer-related pain outcomes showed mixed results. However, in some studies, education had a positive effect on pain intensity. These interventions improved knowledge. Educational interventions are low-risk and can empower patients to self-manage pain. Evidence in this review suggested that ongoing patient contact and reinforcement is needed to maintain any gains from educational interventions. The most effective components and method of education delivery are not clear. This area could benefit from additional research.
