Managing a chronic condition as care reduces

Preparedness writing is dominated by trauma: wounds, fractures, bleeding. Those are dramatic and comparatively rare.

The likeliest serious medical event in a prolonged emergency is far more boring. Someone with asthma, epilepsy, diabetes, heart failure, a thyroid condition or high blood pressure reaches the end of a packet, and there is no repeat prescription.

The likeliest medical crisis

Roughly half of UK adults take at least one regular prescribed medicine, and the proportion rises sharply with age. In most households, someone depends on something.

What running out actually looks like, depending on the condition:

• Asthma or COPD: a preventer inhaler stops and control deteriorates over days to weeks, and a reliever runs out during an attack.
• Epilepsy: seizure control lost, and abrupt withdrawal of some anticonvulsants can itself trigger seizures.
• Diabetes: insulin is the acute one, in days. Oral medication is slower and still serious.
• Heart failure or high blood pressure: deterioration over weeks, and some drugs cause rebound problems if stopped suddenly.
• Thyroid: slow decline over weeks to months.
• Anticoagulants: clot risk on stopping, bleeding risk on continuing without monitoring.
• Mental health medication: relapse, and withdrawal effects that are themselves debilitating.

None of these are treatable with anything in this app, and no herb substitutes for any of them.

Know your own numbers

The single most useful preparedness action here, and it takes an hour.

Most people cannot answer "how many days do I actually have" without going and counting. That is the gap this closes, and it converts a vague worry into a number you can plan against.

Keep a copy in the document pack, one in the go-bag, and one somewhere an older child could find it. It is also the sheet any clinician will want first.

Building a buffer, properly

Which medicines must never be stopped suddenly

Stretching a supply

Honestly, because this is what people will actually try to do, and some ways are much worse than others.

Reasonable, with advice where possible:

• Check whether the dose can be reduced rather than stopped, for conditions where that is meaningful.
• Prioritise the medicines that matter acutely: reliever inhaler, insulin, anticonvulsant, cardiac medication.
• Deprioritise the ones with slow consequences if something has to give: a statin missed for a month is a very different matter from a missed anticonvulsant.
• Reduce demand where you can. Weight, activity, salt, alcohol and smoking all affect several of these conditions, and in a crisis those levers are still available.

Not reasonable:

• Splitting tablets that should not be split. Modified-release and enteric-coated tablets deliver their whole dose at once when broken, which can be dangerous. If it does not have a score line, do not split it without asking.
• Halving insulin doses to make it last. This does not halve the effect and produces sustained high blood sugar.
• Sharing between people.
• Substituting a herbal preparation, which does not work for any of these.

Monitoring without a clinic

Several conditions can be tracked at home with cheap equipment, and knowing the trend is worth a great deal when there is nobody to ask.

Daily weight for heart failure is the underrated one. A gain of a couple of kilograms over a few days usually means fluid retention and precedes breathlessness by days. It is the earliest available warning and it costs nothing.

Peak flow for asthma gives an objective number instead of an argument about whether breathing is worse today, and knowing your own normal is what makes it useful.

Write it down. A trend over two weeks tells you far more than any single reading, and in the absence of a clinician the trend is the diagnosis.

The conversation to have now

• Ask the GP or pharmacist about a buffer, explicitly, and be straightforward about why.
• Ask what happens if this runs out. How fast, what to watch for, and whether it can be tapered.
• Ask which of your medicines are the critical ones, if you take several.
• Ask about a longer prescription interval if you are on something stable.
• Get everything up to date: reviews, blood tests, vaccinations, dental work, an inhaler technique check.
• Get a written summary of your conditions and medicines, and put it in the document pack.
• Make sure someone else in the household knows all of this. If the person who manages the condition is the person who becomes unwell, everything above needs to be findable by somebody else.

This is unglamorous, it involves phone calls rather than equipment, and it will do more good for most households than anything else in this domain.
