Subcutaneous patient-controlled analgesia in palliative care.

Subcutaneous patient-controlled analgesia (SCPCA) is an underutilized method of pain management in palliative care patients. In a select group of patients, including patients in whom enteral analgesia is ineffective or undeliverable, and in patients with limited access to healthcare due to geographical or other logistic issues, SCPCA can provide an effective and safe alternative.
