The Big Picture
Some clients receiving palliative care or living with persistent pain may need pain medication often. Repeated injections may cause discomfort, infection, or skin problems around the injection sites.
Subcutaneous infusion therapy gives pain medication through an injection port or small needle placed in the client’s subcutaneous tissue layer. The medication goes through this port instead of requiring repeated injections into the skin.
If the port or needle becomes dislodged, it may come out of the tissue where it was placed. If that happens, injected pain medication will not provide effective pain relief.

Focus on these core ideas:
- Subcutaneous infusion therapy helps reduce the need for frequent pain medication injections.
- The injection port or small needle sits in the subcutaneous tissue layer.
- The port or needle must stay in the correct position for the medication to work effectively.
- Do not try to move the port or needle.
- If it becomes dislodged, apply pressure with sterile gauze according to Standard Practices and contact your supervisor immediately.

Course Notes: Key Ideas You Need to Know
Why Subcutaneous Infusion Therapy Is Used
Some clients receiving palliative care or living with persistent pain may require frequent pain medication injections. A client may still have pain even when using a topical pain patch.
Frequent injections may cause:
- discomfort
- possible infections around injection sites
- skin problems around injection sites
To avoid the need for frequent injections, some physicians order subcutaneous infusion therapy.
How the Therapy Works
A small needle or injection port is inserted into the client’s subcutaneous tissue layer using Standard Practices.
IV tubing connects to the injection port or needle. The port or needle is then securely taped to the client’s skin.
Pain medication goes through the injection port instead of being repeatedly injected into the skin.
Nova Scotia CCA Note
Sorrentino’s Canadian Textbook for the Support Worker, 5th Edition explains how this therapy works, but it does not say that administering pain medication through the port is a routine CCA duty.
In Nova Scotia, the current Continuing Care Assistant Occupational Standards of Practice describes standard medication assistance such as helping with prescribed daily routine medication and applying specified drops, creams, and ointments. It does not list giving medication through a subcutaneous infusion port as a standard medication-assistance competency. A CCA should not assume that administering medication through this port is part of routine CCA practice. (novascotiacca.ca)
Nova Scotia also sets specific requirements when a task falls outside standard CCA practice and is delegated by a regulated health care professional. Delegated tasks require employer approval, must be client or situation specific, must appear in the care plan, and require training, competency verification , and appropriate supervision. A CCA must not work outside the CCA occupational standards or the employer’s policies and procedures. (novascotiacca.ca)
Why this matters in Nova Scotia: Knowing how subcutaneous infusion therapy works does not by itself give a CCA authority to administer medication through the port. The CCA must stay within current provincial practice requirements and the employer’s directions.

Subcutaneous Infusion Therapy and IV Therapy
intravenous (IV) therapy refers to fluids given through a needle or catheter inserted into a vein. It is also called IV, IV therapy, or IV infusion.
Subcutaneous infusion therapy uses a different location. The injection port or small needle sits in the subcutaneous tissue layer rather than in a vein.
Why the Port or Needle Must Stay in Place
The position of the injection port or subcutaneous needle must be maintained for the pain medication to work effectively.
Avoid: Do not attempt to move the port or needle.
If the port or needle becomes dislodged, it may come out of the subcutaneous tissue. If pain medication is injected after the port or needle comes out of that tissue, the medication will not provide effective pain relief.
What to Do If the Port or Needle Becomes Dislodged
If the injection port or subcutaneous needle becomes dislodged:
- Apply pressure with sterile gauze according to Standard Practices.
- Contact your supervisor immediately.
Exam Clue Words
- Do not: Do not attempt to move the injection port or subcutaneous needle.
- Immediately: If the port or needle becomes dislodged, contact your supervisor immediately after applying pressure with sterile gauze according to Standard Practices.
Fast Review
Focus on these three facts for a quick review.
- Subcutaneous infusion therapy allows pain medication to be given through an injection port or small needle in the subcutaneous tissue instead of through frequent injections into the skin.
- The injection port or subcutaneous needle must stay in position. Do not attempt to move it.
- If the port or needle becomes dislodged, apply pressure with sterile gauze according to Standard Practices and contact your supervisor immediately.
Final Pep Talk
There are only a few key ideas to keep straight here. Focus on where the medication enters, why the port must stay in place, and the two actions to remember if it becomes dislodged.
