Inclusion criteria

Inclusion criteria: Cancer patients currently hospitalized who do not self-administer medical opioids. Patients who have provided informed consent and possess sufficient cognitive function to participate in a pain interview within 24 hours Patients whose resting pain is controlled and whose baseline opioid dosage has been stabilized Patients who have been prescribed rescue opioids to manage breakthrough pain Note Since breakthrough pain is defined as physiologically sudden pain that occurs despite resting pain being controlled by baseline opioid therapy, this study targets patients whose resting pain is controlled and whose baseline opioid dosage has been stabilized.

Exclusion criteria

Exclusion criteria: Patients who do not meet the inclusion criteria Patients under the age of 18 Patients unable to complete questionnaires or similar assessments (e.g., due to cognitive impairment) Patients unable to accurately describe their pain (e.g., unable to answer the NRS) Other, as determined by the principal investigator
