Abstract
Background: Pain perception is a subjective experience and is influenced by a variety of factors. Pain assessment tools, included the numeric pain rating scale (NRS) and the visual analog scale (VAS). A VAS qualitative (VASQ) scale asks patients their current pain level along a continuum of “Good Day,” “Average Day,” or “Bad Day.” We had patients complete both scales and asked them their preference and reason for their choice. Methods: We identified patients 18 years of age and older, seen by Palliative medicine at Geisinger, who had cancer-associated pain of at least one-month duration. Patients filled out the study questionnaire composed of 2 questions. Characteristics of patients who preferred the VASQ were compared to those who preferred the NRS using a 2-sample t tests or Wilcoxon rank-sum tests and Pearson χ2 or Fisher exact tests. The relationship between the NRS and the VASQ used the Pearson correlation coefficient. Results: One hundred forty-six patients completed the questionnaire, 52.1% were female; 63.7% preferred the NRS, 31.5% preferred the VASQ. Patients who preferred the NRS reported a higher NRS rating than patients who preferred the VASQ (mean NRS rating of 6.0 compared to 5.3) but the difference was not statistically significant (P =.1531). Visual analog scale qualitative ratings were higher among patients who preferred the NRS, but the difference was not statistically different (mean rating of 5.2 vs 4.8, P =.3669). Conclusion: Patients preferred the NRS over VASQ for pain assessment. Patients tend to rate their pain at a higher level when using NRS compared to VASQ.
