How I Use My Medical Information Cards

It was during one of my visits to the emergency room while caring for a family member that I realised memory alone isn’t enough. It was something I’d experienced myself just weeks earlier during my own emergency room visit, but the realisation carried a different weight when I was sitting beside someone else, trying to help answer the same questions I’d recently been asked.

Neither of us could recall the name of a new medication they’d started the week before or the name of the specialist they’d recently been referred to. In the stress of the moment, those details simply disappeared.

After many emergency room visits, appointments, medical documents and check-ups, I started noticing a pattern in the questions that were commonly asked and the information that was most useful to have readily available.

The details asked first were usually personal information such as your full name, date of birth and address, emergency contacts, allergies, current medications and medical conditions. That’s what I wanted on the front of the cards for a quick overview and easy reference.

The more in-depth questions usually came afterwards, such as diagnoses (and when they were made), surgeries or procedures, and specialists. That’s why I decided to put those details on the back of the card, as not everyone has surgeries or sees specialists.

The information I use most often is on the front of the card: names, dates of birth, emergency contacts, allergies, medications and medical conditions. They’re usually the first questions asked, so I wanted them to be the easiest details to find.

I prefer the wallet-sized version of the cards because I rarely carry a medical binder with me. Instead, I keep the cards in my phone case so they’re easy to access at all times.

I use them when filling out medical paperwork, answering questions during appointments or emergency situations, and as a reference to make sure I haven’t forgotten anything.

Unfortunately, I’ve also been in situations where I was unable to communicate through speaking or writing. Being able to simply hand over the card allowed me to provide the information clearly. Other times, I’ve just used it as a prompt to read from when my brain fog made recalling details difficult.

Keeping the cards updated means I no longer have to worry about remembering everything for everyone at appointments, check-ups or in an emergency. Between brain fog, fatigue and sleep deprivation, they’ve been a complete game changer. I can either refer to the card myself or hand it straight to the medical professional.

I’ve found it especially helpful to include the month and year of diagnoses and surgeries wherever possible. If you see specialists, adding their name, specialty (for example, endocrinologist) and the clinic they work from also makes the information much more useful.

Initially, I made every family member’s card the same colour, but I quickly realised it was difficult to tell whose card belonged to whom. After a few refinements, I colour-coded each family member instead. Keeping the layout consistent across every card also means I know exactly where to find each piece of information.

I know many people keep this information on their phones. I do too. But in an emergency, handing someone a card is often much quicker than unlocking a phone, opening an app or searching through notes while stressed and overwhelmed.

Over the years, these cards have gone through plenty of changes and refinements, but their purpose has always stayed the same:

To make important information easy to access when it matters most.

Whether it’s a routine appointment, an unexpected trip to the emergency room, or simply trying to remember who takes which medication after a sleepless night, having everything in one place has removed a huge amount of stress from our lives.

They’re not complicated. They’re not fancy.

They’re just one small system that helps our family feel a little more prepared—and one that future me is always grateful for.

Around here, I believe in doing one small thing today that makes life easier tomorrow. These cards are exactly that. They’re a simple system that takes less than an hour to set up but can make appointments, emergencies and everyday life a whole lot less stressful. That’s why I created them—and why I’m sharing them with you.
