Many years ago, I volunteered at a hospital.
One of my duties was filling in for the floor secretary (remember, it was years ago) when she went to lunch or was on break.
As part of the job, I had a copy of the census or a listing of all the patients on that floor, so that when a physician or lab tech came to see a patient, I could direct them to the right room.
Next to each patient’s name was their primary diagnosis.
Almost half of the patients had a diagnosis of sepsis. The Internet was not around at the time, and I left my encyclopedias at home with my parents when I graduated college, so I really had no way of knowing what sepsis was, but I could tell it was prevalent.
