ContextWith increasing attention to the undertreatment of cancer pain in parallel with concerns about opioid misuse, little is known about how patients with advanced cancer adhere to opioid regimens for chronic cancer pain.ObjectivesWe explored patient approaches to managing chronic cancer pain with long-acting opioids.MethodsIn a multimethods study at an academic medical center, adult patients with chronic cancer pain (n = 17) used electronic pill caps to record adherence to prescribed long-acting opioid regimens. After eight weeks, patients viewed their adherence records and completed a semistructured interview about their opioid use. With a framework approach, we coded interview data (Kappa >0.95) and identified themes in how patients perceived and used opioids to manage cancer pain.ResultsPatients (59% female; 94% non-Hispanic white; median age = 65 years) felt grateful about pain benefit from opioids yet concerned about opioid side effects and addiction/tolerance. Main reasons for nonadherence included both intentional decisions (e.g., skipping doses) and unintentional barriers (e.g., missing doses due to inconsistent sleep schedules). Overall, patients set their own opioid adherence goals and developed routines to achieve them. Residual pain varied and was not consistently linked with opioid adherence.ConclusionPatients commonly felt conflicted about using prescribed long-acting opioids to manage cancer pain due to concurrent perceptions of their risks and benefits, and they set their own parameters for opioid-taking practices. Intentional and unintentional deviations from prescribed opioid schedules highlight the need to enhance adherence communication, education, and counseling, to optimize the use of long-acting opioids as a component of cancer pain management.Copyright © 2019 American Academy of Hospice and Palliative Medicine.
