Patient Preferences for Change in Symptoms Associated with Opioid-Induced Constipation

摘要

While opioids have become a standard treatment option for those experiencing moderate to severe chronic pain, side effects of constipation and related symptoms have interfered with their usage in as many as 40-50% of treated patients. Prior research has elucidated the range of these symptoms, but no study has determined which of these symptoms patients most desire improving or whether improving constipation itself by as little as one more bowel movement per week is deemed an important change.
