Clinical benefits and economic cost-savings of remote electrical neuromodulation (REN) for migraine prevention
Abstract
Abstract Aims Assess the clinical benefits and associated direct and indirect cost-savings from Remote Electrical Neuromodulation (REN) for migraine prevention. Methods REN, a prescribed, wearable, FDA-cleared neuromodulation-device for acute and/or preventive treatment of migraine, recently demonstrated efficacy for migraine prevention when used every-other-day, in a prospective, randomized, double-blind, placebo-controlled, multi-center study. Following baseline (4-weeks), subjects underwent treatment with REN or placebo (8-weeks), and electronically reported migraine symptoms and acute treatments daily. Therapeutic-gain was the between-groups difference (REN minus placebo) in change from baseline to the second month of intervention. Health-economics impact was derived as cost-savings associated with REN’s clinical benefits. Results Out of 248 subjects randomized (128 active, 120 placebo), 179 (95:84) qualified for modified intention-to-treat (mITT) analysis. Significant therapeutic gains favoring REN vs. placebo were found (Tepper et al. 2023), including mean (±SD) reduction in number of acute medication days (3.5 ± 0.4 vs. 1.2 ± 0.5; gain = 2.2; p = .001) and presenteeism days (2.7 ± 0.3 vs. 1.1 ± 0.4; gain = 1.6, p = .001). Mean changes of provider visits (reduction of 0.09 ± 0.1 vs. increase of 0.08 ± 0.2; p = .297), and reduction of absenteeism days (0.07 ± 0.1 vs. 0.07 ± 0.2; p = .997) were not significant. Mean annual cost-saving for one patient using REN for…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 248 participants or records.
