I've been interested in the ways that doctors model their thinking for a while -- super-interesting, and I think harder than software-style thinking, as you're trying to work with subjects who are notoriously unreliable, changing all the time, and, you know, basically walking sacks of meat. So this was an interesting book, but I didn't like it as much at Gawande's Complications: A Surgeon's Notes on an Imperfect Science, which is totally fantastic. Groopman has deeper credentials than Gawande, but I found him to be chattier and more anecdotal, and ultimately not as relevant.
