Did you actually violate HIPAA? No. Does it look like you did? Depends who is reading.
Personally, I don't know how anyone doesn't just use the simple alternatives available. Like, a man, a woman, a male, a female, a person, a patient, etc. etc. etc. I've helped maybe two dozen people with their personal statements and it always boggles my mind when people take risks like this. It's not like making a fake name is going to endear the reader... If anything, I'd be annoyed that someone would be willing to risk it. There's like a 3% chance putting the name will make the essay more interesting and like an 80% chance it'll be an opportunity for an ADCOM to whittle down their massive load of potential applicants...
My bad on the rant, I'm not an ADCOM, it's most likely fine, I have just seen these types of things more often than I thought I would. In all seriousness, mentioning the name in your personal statement will probably have little effect on your application compared to your mcat and gpa. Good luck bud.
