Patients with chronic low back pain in treat- ment with opioids often experience episodes of breakthrough pain, but prevalence and treatment preferences data are scarce.

Char- acterization of breakthrough pain in patients with chronic pain secondary to chronic low back pain based on etiology, patholo- gy, and other clinical characteristics. 3. Assessment of the prev- alence of each of the different causes of pain. 4. Identify the possible associations between different types of breakthrough pain and sociodemographic, clinical and healthcare factors.
