I remember watching the behind the scenes on this show. The creator of the show said that they got so much fan mail saying this show was the most realistic hospital show.
My parents both worked in the medical profession my whole life, and when I was watching them come home, I could see echoes of what this show did. All other medical shows were so much about the drama. This one nailed it. It nailed the good, the bad, and everything in between.
Also, I read that Scrubs was more medically accurate than House, Grey’s Anatomy, and every other medical show on TV
"Look again at that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam." - Carl Sagan
