1. Changes in the severity, location, or characterization of pain in patients with solid tumors requires careful and thorough evaluation.

2. Opioids are the cornerstone of management for moderate to severe acute pain. Selection should consider individual patient risk factors, with specific caution for those with impaired kidney function. Morphine, hydromorphone, oxycodone, and fentanyl have distinct profiles and safety considerations.

3. IV formulations are preferred for severe pain due to rapid onset though clinicians should note the variable duration of action among different opioids. All patients require frequent reassessment and possibly dose adjustments to ensure adequate analgesia and to prevent complications such as respiratory depression and oversedation.

4. Practitioners must be aware of implicit biases that may affect opioid administration and prescribing. Studies show disparities in opioid prescriptions for Medicaid, uninsured, Black, or Latino patients in emergency departments.

5. Decisions on hospital admission versus discharge depend on individual cases. Effective communication with the patient's outpatient care team is key for continuity of care and preventing readmissions.
