AIM: We aimed to evaluate real-world outcomes of peripheral nerve stimulation (PNS) used to treat chronic neuropathic pain (CNP) at a tertiary pain management center.
METHODS: Thirty adults who underwent PNS for CNP between June 2015 and September 2021 completed pain and psychosocial assessments in the 6 months before, and 2-3 years after PNS treatment. Pain intensity was measured using the NIH Patient Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Short From (3A). Psychosocial outcomes including depression, anxiety, and sleep disturbance were also measured.
RESULTS: Prior to receiving PNS, long-term responders reported significantly fewer depressive symptoms compared to non-responders (PROMIS depression t-score 50.3 [10.7] vs 57.9 [8.9]; p-value = 0.05). Eleven participants (36.7%) reported long-term treatment response. There was a significantly greater improvement in pain intensity among responders compared to non-responders who reported increased pain (PROMIS Pain Intensity score -9.0 [-4.2] vs. +3.1[+3.2]; p-value < 0.0001).
CONCLUSIONS: Patients report clinically meaningful long-term pain relief after receiving PNS through both 60-day and permanent implant systems, with significant reductions in pain intensity observed in long-term responders. Long-term responders reported fewer depressive symptoms compared to non-responders prior to receiving therapy, emphasizing the importance of psychological screening and psychological optimization prior to receiving PNS.
