Background: Cancer incidence in the world is predicted to increase in the next decade. While progress has been in diagnosis and treatment, much still remains to be done to improve cancer pain therapy, mainly in underserved communities in low-income countries. Objective: To determine knowledge, beliefs, and barriers regarding pain management in both high- and low-income countries (according to the WHO classification); and to learn about ways to improve the current state of affairs. ⋯ Top barriers include religion factors, lack of appropriate education and training at all levels, nonadherence to guidelines, patients' reluctance to report on pains, over regulation associated with prescribing and access to opioid analgesics, fear of addiction to opioids, and lack of discussions around prognosis and treatment planning. Conclusion: The majority of patients with cancer in low-income countries are undertreated for their pain. Promoting cancer pain accredited program of training and education on pain management for physicians and nurses is crucial, as well as advocating policymakers and the public at large.

Patients with injury may be at high risk of long-term opioid use due to the specific features of injury (e.g., injury severity), as well as patient, treatment, and provider characteristics that may influence their injury-related pain management. ⋯ Across this large cohort of multiple, mostly minor, injury types, long-term opioid use was relatively uncommon, but almost all patients with chronic use post injury had preinjury opioid use. Long-term opioid use after injury may be more closely tied to preinjury chronic pain and pain management than acute care pain management.

Preoperative exposure to opioids has recently shown to be associated with poor outcomes after elective major surgery, but little is known as to how pretreatment opioid use affects results of interventional back pain management. ⋯ Pretreatment opioid use is associated with greater pain discomfort, impairment, and reduced functional ability, as well as poorer long-term effect of interventional back pain treatment at one-month follow-up. In our study, opioid users reported the same positive effects of facet joint nerve blocks immediately after the treatment and 2 hours after the treatment, but a significantly smaller effect at one-month follow-up. This could indicate that opioid use may diminish the effects of pain treatments by affecting relearning, behavioral changes, and central pain modulation. These findings may help providers understand the effect of pretreatment opioid use on patient care, and its implications on hospital and societal costs.

Spinal cord stimulation (SCS) is an effective treatment for failed back surgery syndrome (FBSS). In patients with FBSS, opioids have often been initiated, even before SCS is trialed. ⋯ DP did not reduce the use of opioids in patients with FBSS. Opioid doses were lower and dose escalation less steep with continuous SCS therapy.
