Percutaneous electrical nerve field stimulation to reduce clinical opiate withdrawal: a case series

Abstract

Background: Medication-assisted treatment can reduce mortality and withdrawal symptoms, yet treatments can have side effects and are cost ineffective. Research has supported alternative approaches to withdrawal symptoms, specifically percutaneous nerve field stimulator (PNFS); yet, to date, there is a lack of understanding of the initial acceptability within treatment programs. Methods: A retrospective case series evaluated PNFS to reduce opioid withdrawal symptoms for five adult patients participating in an in-home withdrawal management program. The device was worn for five consecutive days, in which a licensed practical nurses monitored their care. Evaluation included the clinical opiate withdrawal scale (COWS) and clinical reviews based on self-report and clinician interview. Results: Significant reductions were noted for all five participants, with the average COWS score for Day 1 at 19.1 reducing to 2.6 at Day 5. In addition, 2-day post-COWS scores demonstrated a continual reduction to 1.4. Qualitative feedback from the patients was recorded, and generalized themes were recorded and addressed. Conclusions: Future controlled, prospective studies should investigate the possibility that PNFS can significantly reduce negative symptoms of opiate withdrawal symptoms, along with providing alternatives to medication-assisted treatments for those who are suffering from opiate use disorder.
