In hospital for something that is not your diabetes: keeping hold of your own insulin
NICE says you should be supported to manage your own type 1 as an inpatient. What the standard covers, what to take in, and what to do if a ward says no.
If you go into hospital for something unrelated to diabetes, a broken ankle, an appendix, a chest infection, the starting point is that you keep running your type 1 yourself. That is the national standard, not a favour.
- NICE says adults with type 1 in hospital are supported to self-manage, and UK inpatient guidance makes that the default unless there is a specific reason against it.
- It gets written down as an agreement to self-manage, signed by you and a registered nurse.
- Ask early for the diabetes inpatient team: they are the people who get called in if you and the ward disagree.
- Bring your own insulin, spare pens, pump supplies, sensors, chargers and hypo treatment (a hypo is glucose below 4 mmol/L).
What you are entitled to ask for
NICE’s quality standard for type 1 diabetes in adults carries a statement on exactly this: adults with type 1 admitted to hospital are supported to self-manage their diabetes. Each statement also spells out what it means for the person it is about, and this one says you are supported to carry on injecting your own insulin if you want to and can do so safely, though sometimes insulin through a drip is needed instead, for example if you cannot eat or are having an operation.
The Joint British Diabetes Societies guidance on self-management in hospital, written for the staff looking after you, is blunter: the default should be that you self-manage unless there are specific reasons not to. On a ward that becomes an agreement to self-manage, a short form you and a registered nurse both sign, covering keeping your insulin where other patients cannot reach it, checking your glucose, and writing down what you have taken. For planned surgery, the moment to settle it is the pre-operative assessment clinic, not the morning of the operation.
Why a ward sometimes takes it over
The same guidance lists when self-management pauses, and some of that is not negotiable. An anaesthetic in the last 24 hours, or patient-controlled pain relief running, means staff give the insulin. So does being on an insulin drip, being confused or drowsy, or arriving with diabetic ketoacidosis. If your glucose levels were the reason you were admitted, self-managing may wait until the diabetes specialist team has seen you.
Kit has its own rules. A pump holds only rapid-acting insulin, so if you cannot manage it yourself it comes off and another route for insulin starts immediately; it is never meant to be removed with nothing in its place. In DKA it comes off because absorption becomes unreliable. With a hybrid closed loop (a sensor and pump running an algorithm together), the guidance is that the algorithm goes to manual while you are unwell, since insulin needs swing about day to day, and closed loop carries on only under specific guidance from the diabetes team.
Asking again, without it becoming a row
The people to ask for are the diabetes inpatient team, often fronted by a diabetes inpatient specialist nurse. NICE expects ward staff to know how to make that team aware when someone with diabetes is admitted, and the inpatient guidance says anyone admitted using a pump should be referred to them. That guidance also names them as the people who advise when you and the ward see it differently, so the sentence that moves things is please can the diabetes team be asked to review this.
Cover is patchier than you would hope. In a national survey across 42 UK organisations and 104 hospitals, specialist support with knowledge of this technology was there in weekday working hours everywhere that replied, but at weekends at only just over half of them. Ask for the hospital’s own self-management policy by name, ask what would need to change for you to take it back, and ask for the answer and its reason to go in your notes. A clinical decision stands while you are on that ward; what you are after is a review by people who know type 1, not a way round it.
What to take in, and why each thing earns its place
Your own insulin can be used on the ward if you have agreed to it, it is in date, the pen or cartridge was opened less than four weeks ago, and the device carries a label with your name on it. Worth checking before you hand over the pen that has lived in the fridge door since spring. Take spare pens too, along with the backup injection plan your team set up for pump failure, because the ward will want to know what it is.
A hospital may not stock your pump’s consumables, since each device takes different parts, so the technology guidance tells people to bring their own infusion sets and reservoirs. If those are not available, pump therapy has to be paused for the rest of the stay. Sensors are the same, although inpatient teams are encouraged to keep a few in. Add the chargers, the phone or reader your sensor talks to, and your own hypo treatment, kept within reach rather than in a locker on the far side of the bay.
What changes from one admission to the next
A hospital stay moves glucose in both directions, and rarely the way an ordinary week does. Illness, pain, stress and steroids push it up. Being nil by mouth, unfamiliar meal times, a smaller appetite and being sick pull it down, and a hypo can come on during the fast itself or hours later, including overnight, when the ward is at its quietest. What the staff around you know varies too: in the same national survey, about one in six organisations had a written policy for using sensors on a ward. None of that means you cannot manage your own diabetes. It is why the guidance asks for regular checks and for the diabetes team to be in the loop.
Three moments this tends to show up
Examples, not instructions or doses.
You are booked in for a hernia repair. The pre-operative assessment clinic is where you say you want to keep managing your type 1, agree what happens on the morning, and get it written down. The guidance says a fast covering no more than one missed meal is often workable on a pump, and that pump users should not need to come in the night before.
You come through A&E with a broken wrist at 11pm, and by morning your insulin is on the drug chart for the nurse to give. Nothing has gone wrong; on an emergency admission the conversation often just never happens. Asking for the agreement to self-manage, and for the diabetes team to be told you are in, is what restarts it.
Your sensor says 5.8 mmol/L and the nurse still wants a fingerprick. That is not distrust. Sensor data does not flow into hospital records, and the ward meters feed the safety systems the diabetes team watches, so expect both to run alongside each other rather than one replacing the other.
Worth paying attention to
Questions that make an appointment useful
When it's urgent
A pump holds only rapid-acting insulin, with no long-acting reservoir behind it, so if it comes off and nothing replaces it, ketones build within hours. If your pump or your insulin is interrupted on a ward and nothing has been started in its place, say so to the nurse looking after you straight away and ask for the medical team. That is the one thing that should not wait for the ward round.
Outside hospital, diabetic ketoacidosis (DKA) is a 999 emergency. Being sick, drowsy, breathing heavily or fast, stomach pain, or breath that smells fruity, alongside a high glucose reading, means 999 or A&E straight away. Do not wait to test ketones first; no test should ever delay that call. If you feel unwell with a high reading but none of those red flags, check ketones if you can and contact your diabetes team or NHS 111.
