About three years ago, I wrote a post titled “Second Language” in which I talked about how learning medicine comes with learning an entirely new set of vocabulary, like a second language. Now, after 11 months of seeing patients, writing progress notes, H&P’s, and consult notes, I’ve picked up another language that builds upon the language of medicine: medical abbreviations.

A year ago, I probably would not have been able to read the above statement, but now it’s second nature to me. Abbreviations continue to be used today by people in the medical field because it lets us write our findings faster, especially if we are pressed with time with many other patients to see. It’s also useful because it makes reading faster as well. Instead of reading “extraocular movements intact,” we could simply and briefly glance at EOMI and know exactly what it means. Ironically, however, over time the abbreviation itself becomes more intuitive to me than what it actually stands for. When I see “PERRLA” now, I instantly know what it means. But when you ask me what it actually stands for letter-by-letter, I’d have to pause for a few seconds to think about it.

While medical abbreviations has its advantages, it also has its disadvantages such as misinterpretation, especially when doctors write with their cursive Chinese calligraphic handwriting that they are so famous for. U’s can be confused with 0’s. IU’s can be confused with IV’s. Because of this, many hospital have discouraged the use of certain abbreviations like QD, QOD, U, IU, MS, and MgSO4, and have a set of approved abbreviations for current use.

Medicine really is a world of its own, with its own culture, knowledge, system, laws, traditions, ethics, practices, and of course, language. The longer we are immersed in it, the more we find ourselves expressing ourselves through it. I’ve heard residents talk like this before: “They’re showing the movie q3 hours. We should go ahead and buy tickets times 2 for the next showing.” I haven’t gotten to that level yet, but perhaps one day I may and not even realize it.
