Dr. Kavin has history of sever OCD which he suffering from since a long time. At one point Dr. Cox mentions this:
Dr. Cox: Boy, I never thought I'd see that guy again! I mean, he had to drop out of our residency class because of the God-awful severity of his condition!
Naturally Kevin has been taking medical help for his condition all his life. From an earlier conversation:
Dr. Cox: Kevin Casey? Holy cow, get outta Dodge! Te-tell me this, are you--are ya shaking hands nowadays?
Dr. Casey: [steeling himself] Well, a lifetime of therapy...and a...whole lotta Zoloft...just so I can appropriately greet you, big guy!
But in those two episodes it is shown frequently that Kevin still suffers substantially because of this OCD - to name a couple of habits, he
- likes to start each day the same way by touching everything in his first patient's room
- gets stuck in a monologue and keeps repeating some particular phrase
- washes hands for a large number of times. Following is the scene:
But in the episode My Catalyst Kevin is shown performing a surgery and that too with incredible speed and efficiency.
But because of his condition isn't it quite possible that he might do something wrong in the surgery which will directly affect the patient? With such reasonably severe OCD how was Kevin able or in fact allowed to perform surgeries?
(With all due respect to people and/or doctors with OCD.)
