Primary Goals and Treatment Approaches in Alleviating Chronic Pain

The primary goal of chronic pain management is to improve quality of life and function while decreasing pain intensity through a multimodal approach that combines non-pharmacological interventions, targeted pharmacotherapy, and interdisciplinary care. 1

Assessment and Goal Setting

• Before initiating any treatment for chronic pain, establish clear and realistic treatment goals with patients that focus on:

  • Functional improvement (physical, emotional, social)
  • Pain reduction
  • Quality of life enhancement
  • Return to daily activities 2

• Use validated assessment tools to evaluate pain:

  • Brief Pain Inventory (BPI) for comprehensive assessment
  • PEG scale for quick assessment of Pain intensity, Enjoyment of life, and General activity 2
  • Document baseline function to measure progress objectively

Treatment Approach

First-Line: Non-Pharmacological Interventions

• Cognitive Behavioral Therapy (CBT) is strongly recommended as first-line treatment for chronic pain 1

  • Promotes patient responsibility for change
  • Develops adaptive pain management behaviors
  • Improves pain-related outcomes, mobility, and mood

• Physical and Occupational Therapy

  • Focus on functional restoration and improved mobility
  • Individualized exercise programs to strengthen and stabilize affected areas 2, 1

• Additional evidence-based non-pharmacological options:

  • Yoga (particularly for back/neck pain and headaches)
  • Hypnosis (especially for neuropathic pain)
  • Acupuncture (moderate evidence) 1

Second-Line: Pharmacological Interventions

• Nonopioid pharmacotherapy should be used when benefits outweigh risks:

  • Gabapentin (first-line for neuropathic pain, titrate to 2400 mg/day) 1, 3
  • Serotonin-norepinephrine reuptake inhibitors (SNRIs) as second-line options
  • Tricyclic antidepressants as second-line options
  • Pregabalin specifically for post-herpetic neuralgia 1, 3
  • Topical agents (capsaicin) for localized neuropathic pain 1

• Opioid considerations:

  • Should not be considered first-line or routine therapy for chronic pain outside of active cancer, palliative, and end-of-life care 2
  • If used, should be combined with non-pharmacological and nonopioid therapies 2
  • Require clear "exit strategy" if benefits don't outweigh risks 2
  • Monitor for drug-drug interactions, especially in patients with HIV on antiretroviral therapy 2

Interdisciplinary Team Approach

• Develop and participate in interdisciplinary teams for complex chronic pain cases 2

  • Pain specialists
  • Behavioral health providers
  • Physical/occupational therapists
  • Social workers

• Particularly crucial for patients with co-occurring substance use or psychiatric disorders 2, 1

Monitoring and Follow-Up

• Regularly assess progress toward functional goals 2
• Document pain intensity, quality of life, and adverse events
• Monitor for adherent versus aberrant behaviors if on opioid therapy
• Thoroughly investigate any new pain reports in patients with previously controlled chronic pain 2, 1

Pitfalls and Caveats

• Avoid focusing solely on pain intensity scores rather than functional improvement
• Don't assume new pain in patients with chronic pain is related to their existing condition - always investigate thoroughly 2
• Be aware that chronic pain can become increasingly complex in its pathophysiology over time, potentially making it more difficult to treat 4
• Recognize that inadequate pain management can lead to significant long-term consequences:
  • Sleep disturbances
  • Cognitive impairment
  • Mental health deterioration
  • Cardiovascular issues
  • Sexual dysfunction
  • Overall reduced quality of life 4, 5, 6

By implementing this comprehensive approach to chronic pain management with a focus on functional improvement and quality of life, clinicians can help the estimated 20% of adults suffering from chronic pain achieve better outcomes and reduce the substantial personal and societal burden of this condition.
