Implantable Peripheral Nerve Stimulation for Chronic Pain Conditions - CAM 10131HB

Description
Peripheral nerve stimulation (PNS) is a percutaneous system consisting of leads, electrodes, and a pulse transmitter that delivers electrical impulses to peripheral nerves. Leads are placed using ultrasound guidance and can be placed for temporary or permanent use in an outpatient procedure.

Summary of Evidence
For individuals who have peripheral, neuropathic, chronic pain who receive peripheral nerve stimulation (PNS), the evidence includes 1 randomized controlled trial (RCT). Relevant outcomes are symptoms, medication use, and quality of life. The RCT reported a statistically significant difference between the treatment group and control group at 90 days in mean reduction in average pain from baseline (27.2% vs. 2.3%; p < .0001) and reported 38% responders, defined as having at least a 30% decrease in the numerical rating scale (NRS) with no upward titration in pain medications, in the treatment group. The RCT had a sample size of 94 with broad descriptions of pain diagnoses, including diagnoses beyond the labeled indications, and a lack of sample population diversity that is not generalizable to the U.S.. There was 51% missing follow-up data at 12 months. Additional evidence from RCTs with larger sample sizes and longer durations of comparative data are necessary to assess the efficacy and durability of PNS. The evidence is insufficient to determine that the technology results in an improvement in the net health outcome.

Background
Peripheral Neuropathic Chronic Pain
Chronic, noncancer pain is responsible for a high burden of illness and can be defined as persistent pain that lasts for more than 3 months.1 Chronic pain of peripheral origin may be caused by damage to peripheral nerves impacting the upper and lower extremities.

Peripheral Nerve Stimulation
Peripheral nerve stimulation (PNS) has been used to treat chronic pain. It is a percutaneous system consisting of leads, electrodes, and a pulse transmitter that delivers electrical impulses to peripheral nerves. Leads are placed using ultrasound guidance and can be placed for temporary or permanent use in an outpatient procedure.

Regulatory Status
A number of PNS devices have been cleared for marketing by the U.S. Food and Drug Administration (FDA) through the 510(k) process. These are listed in Table 1.

Two PNS devices by Stimwave Technologies Inc., the StimQ Peripheral Nerve Stimulator (PNS) System and the Receiver Kit, Trial Kit, Spare Lead Kit, Sterile Revision Kit, SWAG Kit, SWAG Accessory Kit, Charger Kit, were recalled in Sept. 2020 for the product containing a non-functional component not referenced in product labeling.

Policy
Peripheral nerve stimulation as a treatment for chronic pain is investigational/unproven therefore considered NOT MEDICALLY NECESSARY.

Policy Guidelines
Spinal cord and dorsal root ganglion stimulation are covered in policy 70125 and are not reviewed herein.

The Nalu Medical Inc. and Neuspera Medical Inc. device indications state "trial devices are solely for trial stimulation (no longer than 30 days) to determine efficacy before recommendation for a permanent (long term) device."

Coding
See the Codes table for details.

Benefit Application
BlueCard®/National Account Issues
State or federal mandates (e.g., Federal Employee Program) may dictate that certain U.S. Food and Drug Administration-approved devices, drugs, or biologics may not be considered investigational, and thus these devices may be assessed only by their medical necessity.

Rationale
Evidence reviews assess the clinical evidence to determine whether the use of a technology improves the net health outcome. Broadly defined, health outcomes are length of life, quality of life, and ability to function including benefits and harms. Every clinical condition has specific outcomes that are important to patients and to managing the course of that condition. Validated outcome measures are necessary to ascertain whether a condition improves or worsens; and whether the magnitude of that change is clinically significant. The net health outcome is a balance of benefits and harms.

To assess whether the evidence is sufficient to draw conclusions about the net health outcome of a technology, 2 domains are examined: the relevance and the quality and credibility. To be relevant, studies must represent one or more intended clinical use of the technology in the intended population and compare an effective and appropriate alternative at a comparable intensity. For some conditions, the alternative will be supportive care or surveillance. The quality and credibility of the evidence depend on study design and conduct, minimizing bias and confounding that can generate incorrect findings. The randomized controlled trial is preferred to assess efficacy; however, in some circumstances, nonrandomized studies may be adequate. Randomized controlled trials are rarely large enough or long enough to capture less common adverse events and long-term effects. Other types of studies can be used for these purposes and to assess generalizability to broader clinical populations and settings of clinical practice.

Promotion of greater diversity and inclusion in clinical research of historically marginalized groups (e.g., people of color [African American, Asian, Black, Latino and Native American]; LGBTQIA [lesbian, gay, bisexual, transgender, queer, intersex, asexual]; women; and people with disabilities [physical and invisible]) allows policy populations to be more reflective of and findings more applicable to our diverse members. While we also strive to use inclusive language related to these groups in our policies, use of gender-specific nouns (e.g., women, men, sisters, etc.) will continue when reflective of language used in publications describing study populations.

Peripheral Nerve Stimulation for Chronic Neuropathic Pain
Clinical Context and Therapy Purpose

The purpose of PNS in individuals who have peripheral neuropathic chronic pain is to provide a treatment option that is an alternative to or an improvement on existing therapies.

The following PICO was used to select literature to inform this review.

Populations
The relevant population(s) of interest are individuals with peripheral neuropathic chronic pain which may be caused by damage to peripheral nerves impacting the upper and lower extremities that is persistent for longer than 3 months. This population does not include individuals with chronic pain such as craniofacial, migraine, low back and trunk, amputation, or post-traumatic pain.

Interventions
The therapy being considered is PNS. It is a percutaneous system consisting of leads, electrodes, and a pulse transmitter that delivers electrical impulses to peripheral nerves. Leads are placed using ultrasound guidance and can be placed for temporary or permanent use in an outpatient procedure.

Comparators
The following therapies are currently being used to make decisions about PNS: pharmacologic and nonpharmacologic treatments.

Outcomes
The general outcomes of interest are symptoms, medication use, and quality of life.

As a chronic condition, follow-up of at least 6 weeks to 12 months would be desirable to assess outcomes in chronic neuropathic pain.

The Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) recommends that chronic pain trials should consider assessing outcomes representing 6 core domains: pain, physical functioning, emotional functioning, participant ratings of improvement and satisfaction with treatment, symptoms and adverse events, and participant disposition.2 Table 2 summarizes provisional benchmarks for interpreting changes in chronic pain clinical trial outcome measures per IMMPACT.3

Table 2. Health Outcome Measures Relevant to Individuals with Chronic Pain

Outcome Measure (Units) Description Thresholds for Improvement/Decline or Clinically Meaningful Difference (If Known)
Pain intensity 0 to 10 numeric rating scale Patient reported rating of pain intensity. Minimally important (10 to 20% decrease)
Moderately important (≥ 30% decrease)
Substantial (≥ 50% decrease)
Physical functioning Multidimensional Pain Inventory Interference Scale A 60-item self-report inventory of patients' cognitive, behavioral, and affective responses to their condition. Decreasing score indicates improvement. Clinically important (≥ 0.6 point decrease)
Brief Pain Inventory Interference Scale A 7-item self-report assessment of pain interference with physical and emotional functioning and sleep. Decreasing score indicates improvement. Minimally important (1 point decrease)
Emotional functioning Beck Depression Inventory (score) Assessment of depression severity ranging from 0 to 63. Decreasing score indicates improvement. Clinically important (≥ 5 point decrease)
Profile of Mood States Total Mood Disturbance (score) A 65-item checklist of mood disturbances with 6 subscale scores. Decreasing score indicates improvement. Clinically important (≥ 10 to 15 point decrease)
Specific Subscales (score) Clinically important (≥ 2 to 12 point change)
Global Rating of Improvement Patient Global Impression of Change (rating) A single-item rating by participants of their response to treatment in a clinical trial using a 7-point rating scale, ranging from "very much improved" to "very much worse." Minimally important: "minimally improved"
Moderately important: "much improved"
Substantial: "very much improved"

Study Selection Criteria
Methodologically credible studies were selected using the following principles:

  • To assess efficacy outcomes, comparative controlled prospective trials were sought, with a preference for RCTs.
  • In the absence of such trials, comparative observational studies were sought, with a preference for prospective studies.
  • To assess long-term outcomes and adverse events, single-arm studies that capture longer periods of follow-up and/or larger populations were sought.
  • Consistent with a "best available evidence approach," within each category of study design, studies with larger sample sizes and longer durations were sought.
  • Studies with duplicative or overlapping populations were excluded.

Review of Evidence
Systematic Reviews

A systematic review has been published.4 The only relevant RCT from the systematic review is discussed in the following section and the systematic review will not be discussed further here.

Randomized Controlled Trials
Deer et al. (2016) conducted an RCT to assess the safety and efficacy of PNS using the StimRouter Neuromodulation System to treat individuals with chronic pain of peripheral nerve origin.5 Participants (N = 94) were randomized 1:1 into the treatment (n = 45) or control (n = 49) group. The treatment group received PNS and a stable dose of pain medications, and the control group received no PNS and a stable dose of pain medications for 90 days. After 90 days, crossover from the control group to the treatment group was offered. Study visits were planned at 30, 60, and 90 days after randomization, with follow-up at 6 and 12 months. The primary outcomes were pain relief and safety. Average pain at rest was measured by a numerical rating scale (NRS) over 3 months and safety was assessed by adverse events reported during the 1-year study period. A responder was defined as having at least a 30% decrease in the NRS with no upward titration in pain medications. Secondary outcomes included changes in medication, quality of life, patient global impression of change scale (PGIC), and change in worst pain using the NRS. At 90 days, there was a statistically significant difference between the treatment group and control group in the mean reduction in average pain from baseline (27.2% vs. 2.3%; p < .0001). There were statistically significantly more responders in the treatment group compared to the control group (38% vs. 10%; p = .0048). At 90 days, the treatment group compared to the control group had a significantly better improvement in quality of life (change from baseline [mean ± SD]: 1.4 ± 5.9 vs. -0.2 ± 3.4; p = .037) and PGIC (mean ± SD: 4.8 ± 1.5 vs. 2.5 ± 1.9; p < .0001). There were no device related serious adverse events through follow-up (mean duration: 320 days). Study characteristics and results are summarized in Tables 3 and 4. Study limitations are summarized in Tables 5 and 6.

Section Summary: Peripheral Nerve Stimulation for Chronic Neuropathic Pain
The evidence includes 1 RCT. Relevant outcomes are symptoms, medication use, and quality of life. The RCT reported a statistically significant difference between the treatment group and control group in mean reduction in average pain from baseline at 90 days (27.2% vs. 2.3%; p < .0001) and reported 38% responders, defined as having at least a 30% decrease in the numerical rating scale (NRS) with no upward titration in pain medications, in the treatment group. The RCT had a sample size of 94 with broad descriptions of pain diagnoses, including diagnoses beyond the labeled indications, and a lack of sample population diversity that is not generalizable to the U.S. There was 51% missing follow-up data at 12 months. Additional evidence from RCTs with larger sample sizes and longer durations of comparative data are necessary to assess the efficacy and durability of PNS.

The purpose of the following information is to provide reference material. Inclusion does not imply endorsement or alignment with the evidence review conclusions.
