Field kit

Your one-page health brief

Everything a stranger in an emergency department needs to know about you, on one sheet of paper. Fill in what you know, print it, and keep it with your ID.

Imagine you arrive at an emergency department unable to answer questions. The team in front of you has a body, a set of vital signs and no history: no list of your medicines, no idea what is normal for you, nobody to call. Every box below is a question they would ask you if they could.

The brief also earns its keep on ordinary days. Hand it to a new doctor instead of filling in the clipboard from memory, take it to a parent's appointment, or tuck it in an overnight bag. It works the way a pilot's checklist works: the information doesn't depend on anyone remembering it under stress.

Private by design. This page builds your brief inside your browser. Nothing you type is sent anywhere: there is no account and no copy on a server. You have two ways to keep it. "Remember this on this device" saves it in this browser's local storage, and it stays off unless you turn it on. "Save a file" downloads a copy you control, which you can open here again later on any device. That file is plain text and not encrypted, so store it as carefully as you would a copy of your passport.

About you
Who to call

The people a hospital should reach first. Put the most reachable person on top.

Health care proxy (the person who makes medical decisions if you can't)

Allergies and reactions

Medicines, foods, latex, contrast dye. Say what happens, so a nurse can tell an allergy from a side effect.

Medicines

Everything you take: prescriptions, over-the-counter medicines, vitamins and supplements, inhalers, eye drops, creams, injections.

Conditions

Diagnoses you have now or are treated for, with the year each was found.

Surgeries and hospital stays
Implanted devices

Pacemaker, defibrillator, stent, joint replacement, insulin pump, and so on. Keep any device card with the printed page.

Your usual numbers

What's normal for you helps a stranger see what has changed. Leave blank anything you don't know.

Family history

Parents, brothers and sisters, children, grandparents, aunts and uncles: the condition and the age each person was diagnosed. The CDC's guide explains what to collect.

Your care team

Specialists

Advance directive

A living will or medical power of attorney. Say where the signed copy is, so someone can find it fast.

Anything else

The printed page

Keeping it current

A brief with last year's medicines is worse than none, because people will trust it. Update it the day a dose changes, a medicine is added or a diagnosis is made, then reprint and swap out the old copies. The page stamps the date you last edited it and the date you printed it at the bottom, so anyone reading it knows how fresh it is.

For the family history section, start with your parents, brothers and sisters, and grandparents. The CDC suggests recording each relative's major conditions and the age at diagnosis, and some patterns are worth raising with your clinician directly: a mother or sister with breast cancer before 50, or a parent, brother or sister with colorectal cancer before 50. A diagnosis that came unusually young matters more than one that came late.

If you look after a parent, build one for them too, with them at the table. Use "Save a file" for each person so the briefs never get mixed up, and give a printed copy to whoever is most likely to get the phone call.

What stays on this device

Your brief is built and printed in this browser and never sent anywhere. It is saved here only if you tick "Remember this on this device." The button below removes it, along with anything else the field kit has saved in this browser, and empties the form.
