Incidence of Delirium With Different Oral Opioids in Previously Opioid-Naive Patients.

Methods: Subjects were 259 opioid-naive in-patients with cancer who were started on morphine sulfate, oxycodone hydrochloride, or tapentadol hydrochloride extended-release tablets at our hospital between August 1, 2014, and September 30, 2018.
