You’ve probably seen it on a crumpled prescription slip or a frantic note in a hospital chart. A tiny, lowercase "c" with a straight line hovering directly over it. It looks like a typo or maybe a bit of stray ink. It isn't. That little mark is the medical symbol for with, and it’s been a staple of clinical communication for centuries, surviving the transition from parchment to iPads.
It’s weird, right? We have ultra-high-resolution MRIs and AI-driven diagnostic tools, yet doctors are still using Latin-derived scribbles to say something as simple as "with." This symbol is officially known as cum (the Latin preposition for "with"). In a fast-paced ER, writing out four letters—w-i-t-h—actually takes too long. Efficiency matters when you're charting forty patients.
Decoding the Medical Symbol for With and Its Siblings
Medical shorthand isn't just about the letter "c." To understand the medical symbol for with, you have to look at its counterpart: the symbol for "without." That one is a lowercase "s" with a line over it, standing for the Latin sine.
Think about how a nurse might jot down a patient’s status. "Chest pain $\bar{c}$ exertion" tells a specific story. It means the pain happens with movement. If they wrote "$\bar{s}$ exertion," the diagnostic path changes entirely. These symbols act as logic gates in a clinical workflow. They are binary signals that help prevent "charting fatigue," which is a very real thing for residents pulling 24-hour shifts.
The line above the letter is called a macron. In the world of stenography and old-school medical scribing, that macron is the signal that says, "Hey, this isn't just a letter; it’s a shorthand command." You'll also see "p" with a line (post/after) and "a" with a line (ante/before). It's a whole language of squiggles.
Where Did This Stuff Actually Come From?
We can blame the Romans, mostly. Or thank them, depending on how much you value your time. The use of Latin in medicine wasn't just about sounding fancy. For a long time, Latin was the lingua franca of science. It allowed a doctor in London to understand a medical treatise written in Rome or Paris.
The medical symbol for with persists because of the sheer momentum of medical education. Doctors are taught by older doctors who were taught by even older doctors. Even though Electronic Health Records (EHRs) are supposed to standardize everything, the "c-bar" still shows up in "free-text" boxes. It’s muscle memory.

Interestingly, the Institute for Safe Medication Practices (ISMP) has some thoughts on this. They aren't always fans of shorthand. Why? Because a messy "c" can look like an "o" or a "e" if the doctor is rushing. In the 1990s and early 2000s, there was a massive push to eliminate abbreviations to reduce medical errors. If a pharmacist misreads a symbol, the consequences range from "annoying" to "fatal." Despite this, the medical symbol for with is considered one of the lower-risk abbreviations compared to things like "u" for units, which can easily be mistaken for a zero.
The Digital Conflict: Shorthand vs. The Keyboard
The rise of Epic, Cerner, and other electronic charting systems has created a bit of a crisis for the humble medical symbol for with. Keyboards don't have a "c with a bar over it" button.
You can’t just hit a single key to produce $\bar{c}$. You’d have to go into a "special characters" menu or use an Alt-code ($Alt + 0175$ for the macron, maybe?). Nobody has time for that. So, what’s happening? The symbol is evolving or dying, depending on who you ask.
In digital notes, many clinicians have swapped the symbol for "w/" or just "w." It’s faster to type. But when they pick up a pen to sign a physical consent form or a quick bedside note, that Latin "c" comes right back. It’s like a reflex.
There's also the issue of patient portals. Nowadays, you can log in and read your own doctor's notes. When a patient sees "Patient presents $\bar{c}$ cough," they might be confused. Is that a grade? A code? It creates a barrier. Medical literacy is a huge topic in modern healthcare, and using 500-year-old Latin symbols doesn't exactly help the average person understand their own health.
Why Accuracy Still Matters in These Tiny Marks
You might wonder if we're overthinking a single letter. We aren't. In medicine, "with" is a modifier that changes the entire context of a symptom.

Take "Nausea $\bar{c}$ vomiting." That’s a specific clinical picture. Compare that to "Nausea $\bar{s}$ vomiting." One might suggest a blockage or severe infection, while the other might be a side effect of a medication. The medical symbol for with acts as a bridge between two clinical states.
Dr. Bryan Vartabedian, a well-known voice on medicine and technology, has often talked about how the "narrative" of a patient is being lost in the digital age. Short-hand symbols were part of that narrative—they were the "handwriting" of a doctor’s thought process. When we replace them with drop-down menus and checkboxes in a computer, some doctors feel they lose the ability to describe the nuance of a patient's experience.
Real-World Examples of Modern Usage
If you walk into a hospital today, you’ll see the medical symbol for with in these specific places:
- Surgery Consent Forms: Often hand-written by a surgical resident. "Lap chole $\bar{c}$ intraoperative cholangiogram."
- Nursing Flow Sheets: Quick notes during a shift change. "Ambulated $\bar{c}$ assist of 1."
- Physical Therapy Logs: "Patient performed leg lifts $\bar{c}$ 5lb weights."
- Emergency Room Whiteboards: Rapidly updated lists of patient needs.
It’s about brevity. In an environment where every second is accounted for, saving three keystrokes or three pen strokes adds up over a twelve-hour shift. If a doctor writes "with" fifty times a day, that’s 150 extra letters. Over a year? That’s a lot of wasted ink.
Is It Safe? The Debate Over Abbreviations
The Joint Commission, which accredits hospitals in the U.S., has a "Do Not Use" list of abbreviations. This list was created to stop people from dying because of bad handwriting.
The medical symbol for with is not currently on the "banned" list, but it is "discouraged" in many institutions. The problem is that while it's clear to a trained doctor, it's not clear to everyone else in the chain of care. A physical therapist might know it, but what about the medical billing specialist? What about the patient's family?

The trend is moving toward "plaintext." It's the idea that medical records should be written in a way that anyone with a basic education can understand. But medicine is a culture, and cultures don't give up their symbols easily. The "c-bar" is a badge of membership in that culture.
Moving Toward Better Communication
Understanding the medical symbol for with is kinda like learning a secret handshake. It’s useful, it’s historical, and it’s a bit exclusionary. If you’re a patient and you see this in your records, don’t be afraid to ask for a translation.
Honestly, the best thing a clinician can do is write for their audience. If the note is for another doctor, the symbol is fine. If it’s for the patient, just write the word.
To bridge the gap between "Doctor Speak" and "Human Speak," here are a few actionable steps for both sides of the stethoscope:
- For Patients: When you get a copy of your visit summary, look for symbols like $\bar{c}$, $\bar{s}$, or $\bar{p}$. Use a medical abbreviation key (many are available from reputable sources like the NIH) to decode them before your next appointment.
- For Clinicians: If you're using an EHR, set up a "dot phrase" or auto-correct. You can make it so that typing "cw" automatically expands to "with." You get the speed of shorthand with the clarity of full words.
- For Students: Learn the symbols, but don't rely on them. Your goal is to be understood, not just to look like you've been in the game for thirty years. Practice writing clear, concise notes that don't require a Latin degree to decipher.
The medical symbol for with is a fascinating relic. It’s a tiny reminder that medicine is an ancient craft, even when it’s practiced in a room full of glowing screens. It’s not just a letter; it’s a connection between the history of healing and the modern need for speed. Whether it survives another fifty years is anyone's guess, but for now, it remains a silent, barred sentry in the margins of our medical lives.
