Ep. 17 Neuropathic Pain Algorithm

Dan and Juz cover the neuropathic pain algorithm, taking you through first through fourth line treatment options from most to least conservative. They cover trialing and combining various medications including opioids, topicals for focal areas of pain, and various interventional options all the way up to neuromodulation (peripheral or spinal cord stimulators), and pain pumps.

This episode helps a PCP or other physician have a guide to more efficiently work through treatments for neuropathic pain, and patients better understand their options so they can more effectively advocate for themselves.

Introduction

In this episode of "It's not in your head," Dr. Dan Bates and Justine Feitelson (Dan and Juz) delve into the complex world of neuropathic pain, building upon their previous discussions on Number Needed to Treat (NNT) and central sensitization. They present a neuropathic pain algorithm designed to guide primary care physicians (PCPs) through a standardized approach to diagnosis and treatment

Context and Purpose

Dr. Dan Bates developed this algorithm out of frustration with the overreliance on medication and the lack of comprehensive care for neuropathic pain patients. The algorithm aims to:

  1. Provide PCPs with a roadmap for patient care

  2. Incorporate guidelines and conservative approaches

  3. Address the issue of limited access to treatment options

  4. Offer a starting point for treatment based on individual patient history

Current Challenges in Neuropathic Pain Management

  • Lack of consensus in diagnosis and treatment

  • Need for standardization, especially for complex pathologies

  • Long delays in diagnosis for conditions like Complex Regional Pain Syndrome (CRPS)

  • Insufficient guidelines for post-intervention care

Diagnostic Approach

Patient History and Examination

  • Recognize the inherent unreliability of patient histories

  • Focus on identifying pain drivers and amplifiers

  • Assess the level of sensitization and mood

  • Determine appropriate tests and further investigations

Quantification and Definition

  • Gather information to define pain characteristics

  • Evaluate the extent of central sensitization

  • Consider the impact of sleep, fatigue, and mood on treatment targets

Treatment Algorithm

First-Line Treatments

  1. Multidisciplinary care (MARS - Movement, Analgesia, Rehabilitation, Self-management)

  2. Address pain amplifiers and co-existing conditions

  3. Focus on pain acceptance and catastrophizing

  4. Implement pain science education

Pharmacological Interventions

First-line Medications

  • Consider side effects and their potential to amplify pain

  • Regularly re-evaluate medication efficacy

  • Aim for long-term symptom improvement without compromising future treatment options

Second-line Medications

  • Explore combination therapy

  • Consider topical treatments for localized pain

  • Discuss ketamine therapy options and limitations

Interventional Treatments

  • Epidural injections (common in CRPS)

  • Pulse radiofrequency for nerve injury-related CRPS

  • Sympathetic blocks (short-term relief for CRPS)

  • Spinal cord stimulators (with trial periods)

Opioid Considerations

  • Understand the potential for opioid-induced hyperalgesia

  • Recognize opioids as a short-term solution with long-term consequences

  • Be aware of the impact on patient autonomy and agency

Importance of Holistic Care

  • Implement MARS principles throughout treatment

  • Address lifestyle factors and eliminate other variables/contributors

  • Provide ongoing support and individualized care plans

  • Emphasize the connection between treatment and patient goals
