At the clinic I volunteered at, I had to opportunity to file reports from doctors in various fields. The most difficult part is deciphering their hand writing and short hand notes. I have compiled a list of abbreviations that I have come across repeatedly. This is a list of common abbreviations. If there is anything you cannot read or do not know, guess the word and search it on Google. I do this by searching

“__(word/abbreviation I guessed)__ medical abbreviation”.

Read about how I decipher a doctor’s handwriting here.

Caution!

Some abbreviations should not be used because it can have multiple meanings or can be easily mistaken for something else if handwriting is sloppy. There are some health care providers who believe that given the context and sufficient medical training, these abbreviations should not be a problem and is common sense. Personally, as a health care worker, we should know better than to assume others understand what we mean. Different people interpret the same thing differently. It is better to assume the other person have the very basic medical knowledge and go from there. Therefore, it would still be in the person who is reading it and the patient’s best interest if the full word is written out whenever possible. Don’t be lazy, write clearly!
