Insulin teaching often happens in the same visit as a dressing change. The patient is anxious, the wound needs measuring, and the chart still has to show what was taught. This guide covers what to teach about insulin for a patient with a diabetic foot ulcer, and how to document it cleanly from a phone or tablet at the bedside.
Why insulin education belongs in the wound note
Steady blood glucose is what lets a diabetic foot wound close. When pills aren't enough, insulin is the tool, and fear of injections is often the real barrier. Pens use very fine needles that most people barely feel, and injections are quick. Saying so plainly, and recording that you did, makes the teaching part of the wound care plan rather than a side conversation.
A mobile wound care documentation workflow helps here. You can capture the wound image, record measurements, and note the education in one sitting instead of reconstructing it later at a desk.
What to cover with the patient
Keep the teaching short and concrete. A reliable checklist:
- Site selection: insulin goes into the fat just under the skin: abdomen, outer thigh, outer arm, or outer gluteus.
- Technique: pinch the skin gently and flat, and rotate sites every time so the tissue stays healthy.
- Needle safety: needles are single use, never shared, and go into a sealed, rigid container, never the trash.
- Storage: open insulin stays at room temperature for about 28 days, with spares in the refrigerator.
- Adherence: never skip doses while a wound is healing.
The pen sequence, step by step
Teach it as four steps and have the patient repeat it back:
- Prepare: wash hands and attach a fresh needle.
- Safety test: dial 2 units and press until a drop appears at the tip.
- Dose and inject: dial the prescribed dose and inject.
- Hold for 10 seconds: so the full amount enters.
A teach-back is worth recording. Note whether the patient completed each step correctly, not only that a handout was given.
When only a syringe is available
A syringe works if there is no pen. The patient draws air equal to the dose, pulls the insulin, clears bubbles, pinches the skin, inserts at 90 degrees, pushes the plunger, counts to ten, and removes the needle.
The highest-risk detail is the tuberculin syringe. On it, 0.2 mL equals 20 units and each line is 1 unit. Confusing milliliters with units causes dangerous dosing errors, so it should be used only if nothing else is available. If a patient is using one, document that you reviewed the markings with them.
What to chart
A useful education entry is short and specific:
| Element | Example of what to record |
|---|---|
| Device | Pen or syringe type |
| Sites reviewed | Abdomen, thigh, arm, gluteus; rotation discussed |
| Technique | Safety test and 10-second hold demonstrated |
| Safety | Needle disposal and no-sharing reviewed |
| Syringe warning | Units vs. mL reviewed, if applicable |
| Understanding | Teach-back result, patient concerns |
Pair this with the wound's measurements and photo so the record shows both the intervention and the healing trend. Tools built for diabetic foot care documentation keep these pieces together, and the main site at woundscribe.ai shows how that fits a wider charting workflow.
Patient-facing material
If you want a plain-language walkthrough to share, the original DFU Manual episode on insulin covers the four reasons not to fear insulin, the pen and syringe sequences, and six safety habits. It comes from Alianza Para El Salvataje del Pie Diabético Perú. Pointing patients to it, and noting that you did, reinforces what you taught in the room.
The takeaway
Insulin is quick, low-pain, and supports wound closure. Teach the sites, the steps, the syringe caution, and the disposal rules, then chart each one so the next clinician sees exactly what the patient knows.
