STUDY PURPOSE: To evaluate the effectiveness of healthcare interventions targeting pain in patients with cancer
TYPE OF STUDY: Systematic review
DATABASES USED: PubMed, CINAHL, PsycINFO, DARE, and Cochrane Collaboration; reference lists were used to identify additional studies.
KEYWORDS: Search terms and strategy specifics are in an online appendix to this article.
INCLUSION CRITERIA: Random or nonrandom trials with a control group. Patient-centered and institutional change interventions were included in the definition of healthcare interventions. Pain was included as an outcome.
EXCLUSION CRITERIA: Not specified
TOTAL REFERENCES RETRIEVED = 1,3014
EVALUATION METHOD AND COMMENTS ON LITERATURE USED: GRADE system of quality evaluation; risk of bias was high in seven studies and moderate in another seven studies.
APPLICATIONS: Palliative care
Of the studies, 89% examined patient educational activities. Two focused on provider-level interventions. Fifty-five percent of studies (11 studies) that measured knowledge and barriers found significant improvement in barriers to pain management. Five studies measured pain knowledge–two of these showed improvement. Forty-seven percent of the 19 studies showed significant improvement in pain outcomes compared to the control group. Findings varied by the type of intervention used, and results suggest that the use of multiple educational modalities may be more effective. The number of patient encounters in studies varied widely.
Psychoeducational interventions significantly can reduce barriers to pain management, improve pain knowledge, and improve pain outcomes.
Psychoeducational interventions can reduce patient barriers to pain management, improve relevant knowledge, and have a positive impact on pain. Multimodal interventions combining various educational media and follow-up appear to be more effective than alternatives. Data are limited to show effects of institutional, provider-focused interventions, but results in this area are promising. A combination of provider- and patient-focused interventions should be evaluated.
