Adult pain scores in the emergency department: a scoping review protocol.

Introduction: Pain is a common complaint in patients presenting to an Emergency Department (ED). Data show that timely delivery of pain relief in this setting remains a challenge. Adequate treatment of pain requires recognition and assessment. The Royal College of Emergency Medicine advocates for early pain assessment and reassessment post-analgesia; however, it does not specify how best to do this. Therefore, a review of existing literature is needed to identify which pain assessment tools have been shown to be useful in the ED.

Methods and analysis: This scoping review will use the Joanna Briggs Institute methodology. A search of PubMed, Embase, Cumulated Index in Nursing and Allied Health Literature, Web of Science, Scopus and the Cochrane Library will identify relevant studies published in English since January 2004. Studies will be included that recruit adults (aged 18 years and over) presenting to an ED with acute pain (duration under 3 months). Publications must assess or compare tools for measuring pain in an ED setting. Full-text articles published internationally will be considered. After duplicate removal, abstract screening and full-text analysis by two independent reviewers will identify relevant papers, using the inclusion criteria. Discrepancy resolution will be via a third reviewer. Pain measurement tools and their evidence will be extracted, collated and described. The findings will be reported according to Preferred Reporting Items for Systematic reviews and Meta-Analyses for Scoping Reviews.

Ethics and dissemination: Ethical approval is not required for this review. Published results will be shared with relevant parties interested in ED pain management. Potential next steps include patient involvement in the evaluation of pain assessment tools identified in this review and implementation into practice. The insights of patients with relevant lived experience in assessing these tools would be invaluable to the objective of improving pain management in the emergency setting.
