"Where Does It Hurt?" - good read, BTW
I didn't explicitly say so in the article above, but the book is a good, engaging read. You may or may not agree with all of it, but Bush makes his case with a lot of good examples, sometimes but not always featuring Athenahealth customers. Co-author Stephen Baker apparently did most of the writing, but he does a good job of capturing Bush's style and sense of humor. The Athenahealth origin story is presented in the context of explaining what's frustrating about trying to run a business in healthcare and overall I didn't find the book to be terribly self-serving.
Bush and Baker also devote a fair amount of time to examining different perspectives, at one point including an interview with one of the authors of the Affordable Care Act for his insights about the frustrating compromises that went into turning the bill into a law, the underlying problems that were too fundamental and politically sensitive to tackle.
Book jacket blurbs from people like Atul Gawande (surgeon, professor, and author of The Checklist Manifesto) and John Halamka, CIO of Beth Israel Deaconess, reflect the fact that others see some serious thinking at work here.
