Background:
Pain assessment plays an important role in dermatologic surgery. The numeric rating scale (NRS), visual analog scale (VAS), verbal rating scale (VRS), and Faces Pain Scale (FPS) are commonly used scales for pain measurement. Conflicting evidence exists regarding the use of each. Prompt pain recognition and treatment during procedures result in higher patient satisfaction.
Objective:
Determine the most applicable scale for acute pain measurement in dermatologic surgery.
Materials And Methods:
This systematic review was performed in accordance with PRISMA-Supplemental Digital Content 4, http://links.lww.com/DSS/A976 (PROSPERO; CRD42018091058). PubMed, Cochrane, EMBASE, Scopus, and Web of Science were searched between April 24, 2018, and May 06, 2018. The search query consisted of pain, pain measurement (NRS, VAS, VRS, and FPS), and assessment/comparison. The inclusion criteria included English language literature with primary/secondary outcome objectives directly comparing ≥2 pain scales in acute pain (age: 13+). Study end points included interscale correlations, patient preferences, provider preferences, study author recommendations, and failure rates.
Results:
Eight hundred seven studies were retrieved: A total of 42 studies were included. The visual analog scale (n = 42) was most studied, followed by NRS (n = 29), VRS (n = 27), and FPS (n = 11). 93.1% studies showed a high statistical correlation between VAS and NRS. Patients preferred NRS (n = 8/11), followed by FPS (n = 3/11), VRS (n = 2/11), and VAS (n = 1/11). Study authors recommended NRS/VAS (n = 8/19), VRS (n = 6/19), and FPS (n = 1/19). Providers preferred NRS (n = 2/3) and VRS (n = 1/3). The visual analog scale had the highest failure rate (n = 11/12).
Conclusion:
The numeric rating scale is most applicable for dermatologic surgery because of reported patient and provider preferences, lowest failure rates, and most frequent study author recommendations.
