Multicenter Study
Prevalence and characteristics of breakthrough pain in patients receiving opioids for chronic back pain in pain specialty clinics.
We sought to assess the prevalence and characteristics of breakthrough pain (BTP) in patients with chronic back pain. ⋯ These patients with opioid-treated chronic back pain commonly experienced BTP, which often had a rapid onset and a relatively short duration and was difficult to predict. Opioids were the mainstay of pharmacologic therapy, but nonopioid analgesics and adjuvant analgesics were commonly used.
