Battlefield Acupuncture vs Ketorolac for Treating Pain in the Emergency Department.

Abstract

Background: Many patients arrive in the emergency department (ED) with acute pain. Battlefield acupuncture (BFA) uses small, semipermanent acupuncture needles in 5 set points anatomically located on each ear to reduce pain in a few minutes. Pain relief can last months, depending on the pathology of the pain. At the Jesse Brown Veterans Affairs Medical Center (JBVAMC) ED, ketorolac 15 mg is the preferred first-line treatment of acute, noncancer pain. In 2018, BFA was offered first to veterans presenting with acute or acute-on-chronic pain to the ED; however, its effectiveness in pain reduction vs ketorolac has not been evaluated in this patient population. The objective of this study was to determine whether BFA monotherapy was noninferior to ketorolac 15 mg for reducing pain scores in the ED.

Methods: This study was a retrospective, electronic chart review of patients who presented to JBVAMC ED with acute pain or acute-on-chronic pain and received ketorolac or BFA. The primary endpoint was the mean difference in the numeric rating scale (NRS) pain score from baseline. Secondary endpoints included the number of patients receiving pain medications, including topical analgesics, at discharge and treatment-related adverse events in the ED.

Results: A total of 61 patients were included in the study. Baseline characteristics were similar between the 2 groups except for the average baseline NRS pain score, which was higher in the BFA group (8.7 vs 7.7; P = .02). The mean difference in NRS pain scores from baseline to post-intervention was 3.9 for the BFA group and 5.1 for the ketorolac group. The difference in reducing the NRS pain score between the intervention groups was not statistically significant. No adverse events were observed in either treatment group.

Conclusions: For treating acute and acute-on-chronic pain in the ED, BFA did not differ compared with ketorolac 15 mg in NRS pain score reduction. This study's results add to the limited existing literature suggesting that both interventions could result in clinically significant reductions in pain scores for patients presenting to the ED with severe and very severe pain, indicating BFA could be a viable nonpharmacologic treatment option.
