When to Use

When to Use

  • Rapid assessment of chronic pain in primary care and specialized pain clinics.
  • Monitoring functional interference of pain during long-term opioid or non-opioid therapy.
  • When the full Brief Pain Inventory (BPI) is too lengthy for a busy clinic visit.

How it Works

Variables

  • P - Pain intensity (0-10 on average over the past week).
  • E - Enjoyment of life interference (0-10 over the past week).
  • G - General activity interference (0-10 over the past week).

Practical Pearls

Clinical Pearls

  • The PEG is derived directly from the BPI (Brief Pain Inventory) and has been validated to be just as responsive to clinical changes.
  • A 30% reduction in the PEG score is universally considered a clinically meaningful improvement for chronic pain patients.

Next Steps

Interpretation

  • Document baseline score prior to opioid initiation or major intervention.
  • Track at every follow-up visit. If the PEG score fails to improve by ≥30%, reassess the efficacy and safety of the current analgesic regimen.
