Insulin-treated diabetes: what a nursing visit changes

Injection, blood glucose, feet, hypoglycaemia alerts: the exact role of the home nurse for a person on insulin, and what stays in the hands of the patient and the doctor.

Key points
- The visit is not just the injection: it secures the dose, the monitoring and the early detection of complications.
- Hypoglycaemia is corrected first, before any other decision, including the planned injection.
- Weekly foot checks prevent more amputations than any dose adjustment.
- A nurse adjusts a dose only under a protocol written by the doctor; otherwise the nurse calls.
Why a nurse visits, when the injection looks simple
Injecting insulin is technically simple. Deciding whether today's planned dose is still the right one is not: after a night without food, a stomach bug, a course of steroids or a fall, the same dose no longer has the same effect.
So the visit does three things: administer, check the context, and detect what the person does not report spontaneously — a damaged foot, new confusion, weight loss.
It also makes independence possible: many patients take their injections back into their own hands after a few weeks of support, and that is an explicit goal, not a failure of care.
The cold chain of an insulin pen, at home
One rule holds the whole chain: what has been started and what has not are not stored in the same place.
Pharmacy
Dispensing follows a prescription; the trip home should stay short.
Cold reserve
Unopened pens wait in the fridge, never against the back wall and never in the freezer.
Pen in use
The pen in use is kept at room temperature, away from sunlight and heat.
Nursing visit
We check the look of the product and the opening date before each injection.
Disposal
Used needles and pens go into the dedicated sharps container, never the household bin.
How a visit unfolds
Order matters: each step conditions the next.
Blood glucose check
Measured before the injection when prescribed, or read from the sensor. The figure is recorded with the time — a figure without a time cannot be interpreted.
Reading the context
Meal taken or not, unusual activity, vomiting, fever, new medicine. This is what changes insulin requirements.
Administration
Prescribed dose, injection site rotated to avoid lipodystrophy, needle disposed of immediately in a DASTRI container.
Monitoring and handover
Recorded in the care file, and reported to the doctor if a protocol alert threshold is crossed.
Hypoglycaemia and hyperglycaemia: recognise, act
These markers are there to prompt action, not to diagnose. Exact thresholds are in the personal protocol given by the doctor.
| Situation | What is observed | What is done |
|---|---|---|
| Hypoglycaemia | Sweating, shaking, sudden hunger, pallor, confusion, unusual aggression | Immediate sugar intake, recheck after 15 minutes, then a snack. Call 15 if the person cannot swallow. |
| Moderate hyperglycaemia | Thirst, frequent urination, fatigue | Hydration, closer monitoring, report to the doctor per the protocol. |
| Hyperglycaemia with general signs | Nausea, abdominal pain, unusual breath, drowsiness | Call the doctor without delay: this can deteriorate quickly. |
| Foot wound | Redness, blister, crack, painless wound | Reported the same day: in a person with diabetes, a foot wound is always taken seriously. |
Feet: the check that changes the outcome
Neuropathy removes pain: a wound can develop unnoticed. The examination is therefore systematic, not triggered by a complaint.
- Look at the sole, the heels and between the toes, including when all seems well
- Check shoes and socks: a seam, a stone or a new shoe is enough
- Report any lesion, however small, the day it is seen
- Never use corn remedies or cut away hard skin yourself
- Keep the skin supple, without moisture trapped between the toes
What the nurse decides, and what the nurse does not
Dose adjustment belongs to the nurse only where the doctor has written a named protocol with explicit thresholds. Outside that frame, the prescribed dose is given and the doctor is contacted.
This limit is not administrative caution: it guarantees that no decision rests on one person's interpretation on a tired day.
Any lasting change of treatment goes through the doctor. The nurse alerts, documents and administers — the nurse does not prescribe.
Cover and supplies
Insulin-treated diabetes is a recognised long-term condition: related care is covered in full on the basis of health insurance tariffs, subject to the prescription and protocol in place.
Insulin, needles, meter, strips and sharps container are all prescribed; we check stock at every visit to avoid a weekend shortage, the leading cause of a missed injection.
Used needles are disposed of only in an approved container, taken back by the pharmacy through the DASTRI channel.
What we check at every visit
The procedure takes a minute; the checks around it are what make the visit useful.
- Agreement between the current prescription and what is administered.
- Appearance and storage of the open pen or vial.
- Rotation of injection sites and skin condition where they are used.
- Blood glucose results available since the previous visit.
- Meal taken or planned, consistent with the prescribed schedule.
- Remaining stock: insulin, needles, test strips, sharps container.
Situations that disturb the usual schedule
Gastroenteritis, a feverish infection, a skipped meal, unusual exertion or a recent hospital stay all change the balance. On those days the rule is not to improvise but to inform: adjustment belongs to the doctor.
We always record such episodes, because they often explain a run of results nobody would understand three weeks later.
When to call
Faintness, sweating, trembling, confusion, unusual drowsiness, repeated vomiting, inability to eat, a foot wound however small: call without waiting for the next visit.
Any foot wound in a person with diabetes is shown quickly: that is a rule, not excessive caution.
What we report to the doctor
We report the recorded results, unusual episodes — faintness, a skipped meal, an infection, a hospital stay — the condition of injection sites and observed adherence, without judgement.
We do not report an interpretation. The decision to adjust belongs to the doctor, and it is better when based on a dated series than on an average recalled over the phone.

Independence, where it is possible
Many patients give their own injection part of the time. The nursing visit can then focus on what deteriorates silently: injection sites, storage, and the match between the prescription and what is actually done.
Independence is neither decreed nor withdrawn as a precaution: it is reassessed, with the doctor, when the situation changes.

Terms explained
- HbA1c
- Glycated haemoglobin: reflects diabetes control over the past two to three months, unlike a single blood glucose reading.

- Long-term condition (ALD)
- A chronic condition recognised by French health insurance, granting 100 % cover for care related to that condition.
- Care protocol
- A written, dated description of how a specific patient's care must be delivered: products, supplies, frequency, alert criteria.
- Handover notes
- The written record of a visit: what was done, what was observed, what must be watched. The shared memory of the care episode.
- Sharps waste (DASRI)
- Infectious healthcare waste — needles, syringes, lancets — collected in an approved yellow container, never in household waste.
