Characterising pharmacists' interventions in chronic non-cancer pain care: a scoping review

BACKGROUND

Chronic non-cancer pain may affect up to 51% of the general population. Pharmacist interventions have shown promise in enhancing patient safety and outcomes. However, our understanding of the scope of pharmacists' interventions remains incomplete.

AIM

Our goal was to characterise pharmacists' interventions for the management of chronic non-cancer pain.

METHOD

Medline, Embase, PsycINFO via Ovid, CINAHL via EBSCO databases and the Cochrane Library were systematically searched. Abstracts and full texts were independently screened by two reviewers. Data were extracted by one reviewer, and validated by the second. Outcomes of studies were charted using the dimensions of the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT).

RESULTS

Forty-eight reports were included. Interventions ensuring appropriate drug prescription occurred in 37 (79%) studies. Patient education and healthcare professional education were reported in 28 (60%) and 5 (11%) studies, respectively. Therapy monitoring occurred in 17 (36%) studies. Interventions regularly involved interprofessional collaboration. A median of 75% of reported outcome domains improved due to pharmacist interventions, especially patient disposition (adherence), medication safety and satisfaction with therapy.

CONCLUSION

Pharmacists' interventions enhanced the management of chronic non-cancer pain. Underreported outcome domains and interventions, such as medication management, merit further investigation.
