Why should docs care about big data?

'When we're not doing that, I think we're not following our Hippocratic Oath'

When he speaks at Healthcare IT News' Big Data & Healthcare Analytics Forum next month in Boston, Robert Wachter, MD, will have some provocative things to say about quality and safety – and the responsibility physicians have to embrace the promise of business and clinical intelligence.

Being provocative and innovative is what Wachter – widely read at his blog, Wachter's World, and followed on Twitter (@Bob_Wachter) – is good at.

Associate Chair of the Department of Medicine at University of California San Francisco, Wachter is a pioneer of the hospitalist field (he coined the term), a medical specialty that focuses on primary care in inpatient settings. He's a past-president of the Society of Hospital Medicine and has helped the specialty become the fastest growing in healthcare.

Wachter is also author of a forthcoming book, due out in 2015, titled, The Digital Doctor: Hope, Hype, and Harm at the Dawn of Medicine’s Computer Age. In it, he explores the consequences, both hoped-for and unintended, of the great health IT revolution.

On Thursday, Nov. 20, at the Big Data & Healthcare Analytics Forum, Wachter will deliver a talk titled, "The Value Agenda: Why Quality, Safety, and Patient Satisfaction are No Longer Elective." In it, he'll discuss how physicians must make smart use of data and analytics – not just to heal their own patients but also to help improve the prognosis of the healthcare industry itself.

We spoke to Wachter recently from Boston, where he's taking a sabbatical from UCSF to finish up his book.

Q: Tell us a bit about yourself and about how you helped create the hospitalist specialty.

A: I'm a general internist and an academic physician. My career can best be explained as "What happens when a political science major becomes an academic physician." I got very interested in how the system works, or doesn't.

In the mid-90s I was given a new job: to run the inpatient medical service at UCSF Medical Center, a big academic hospital. I had a very smart boss, and he said, "The service looks like it's organized when I was a resident here 20 years ago. That can't be right. Come up with some new model."

I started sniffing around to see who was doing innovative things in inpatient care. And I started to hear tales of different ways of doing it. The overarching theme was moving from the old model of your primary care doctor taking care of you in the hospital to a new model where a separate doctor did that. You can argue there are a lot of reasons why that might be a bad idea, in terms of discontinuity. But it struck me as probably being a good idea.

And being in keeping with what happened with the rest of medicine – if you think about it, in the old days there were no separate intensive care unit doctors, no separate emergency room doctors. You expected your own doctor to go there and take care of you. And then over time people said, "That doesn't work. These places are really complicated. We need someone who's there all the time. Who lives there. Who understands the system well."

And so I organized a model of doing that in my own hospital and wrote an article in the New England Journal of Medicine that coined the term “hospitalist.” I started getting calls from hospitals all over the country saying, "This is exactly what we need. Come out here, and tell us how to do it."

More interestingly, I began getting calls from doctors who said, "I've been doing this for five years here in Springfield, Mass., or Gainesville, Fla., and I thought I was the only one in the country.” I thought it was local and idiosyncratic or had to do with the nuances of payment or physician structure and preferences.

That's when I realized something interesting and organic was going on. And to make a long story shorter, that was 1996, and we're now almost 20 years into it. It's the fastest growing specialty in the history of medicine. Over 40,000 doctors now, a thriving professional society, all the attributes of a specialty: textbooks, meeting, board certification.

The evidence, by and large, supports the premise I had in the beginning. Concerns remain, though, which is why I got interested in technology. We do need to figure out now how to move information effectively from one doctor to another doctor, from one setting to another setting. But we have to do that all over the place in medicine.

By and large, I think it works better: The idea of having your own primary care doctor take care of you in the hospital sounds romantic and sounds terrific. When Marcus Welby did it, it was great.

But it just doesn't work. Patients are too sick in the hospital. They really need someone to be there, and primary care doctors are too busy in the office juggling the balls they're juggling. I think this is a better mousetrap.

Q: It's clearly an idea that's found a need. That's got to be gratifying.

A: At the Society of Hospital Medicine meeting, I get chosen each year to give the closing address: speaking to 2,500 or 3,000 people who really want to do the right thing. My group at UCSF is now 60 physicians. They're amazing people, and they do great things every day.

I'd say the most gratifying thing was a very lucky break. As the field began to grow, we came of age at precisely the same time as the healthcare industry was being pushed to transform itself in ways that were very different than what I grew up with. We were being pressured quite vigorously to figure out how to provide high quality, safe, satisfying care at a cost that won't bankrupt the country.

A lot of other physician groups said, "Leave us alone; we're too busy." For our field, since we're a brand new field, and a generalist field, we don't have a procedure, per se. We said, “Terrific. That's exactly correct. That's exactly what we need to be doing.”

So we jumped in with both feet to this idea of value improvement, the idea of making the system we work in work better.

And what's unbelievably gratifying now is to see leaders in hospitals all over the country emerge from this field. The top physician in Medicare is a hospitalist. The surgeon general nominee is a hospitalist. They are really emerging as national and local leaders. Many CMIOs are hospitalists.

That's not surprising to me. It's born of the field's driving and founding philosophy, which is: We are here not just to take care of the individual patients but to take care of this other really sick patient which is the healthcare system.

Each one deserves a lot of attention, and each one is hard, and each one requires special training. The same rigor you put into being a really good doctor – to diagnose people and know how to treat them – we also need to get trained to diagnose the system, when it's screwed up, and make it work better. I'd say that's the most gratifying thing of all, seeing that all come together.
