As you said, many clinicians write medical records and prescriptions like poor "calligraphers".
I have been engaged in clinical work for a long time and have some understanding of this phenomenon. Now I would like to put forward several possibilities for discussion:
First, the more brilliant doctors receive patients, the time is always not enough. Imagine if a doctor needs to see 40 outpatients every morning, and often the previous patient is not treated well, and one patient is impatient. In this case, as a doctor, you must speed up your writing. As long as colleagues in laboratories, pharmacies and other departments can understand it, they will often "scribble" as soon as possible, even if they are ridiculed as "calligraphers" by others.
Second, in order to make others look more sophisticated and knowledgeable, young doctors often deliberately write their own words like "Dragon and Phoenix Dance", which makes people unable to understand. This situation is not common among junior doctors, but at least they had this idea and practice decades ago.
Third, except for Chinese medicine, many doctors in western medicine have never really worked hard on writing, so the writing itself is not good. Coupled with the hurry and other reasons, what they write is often worse and uglier.
There are other reasons that are difficult to describe, but the above reasons are probably the most common. Of course, poor handwriting is definitely a bad habit, but if you encounter the first situation, please forgive me. Although the latter problem is not good, it definitely needs improvement.
I hope you will feel less disgusted after reading it?
The above is for reference only.
