The Health Care Productivity Problem

I’ve blogged twice already about David Cutler’s recent NBER paper on inefficiencies and costs in the health care system. It’s worth some attention and it is an easy read, so I recommend checking it out  in full. It includes the following figure (original source: Oliner et al., 2007).


Cutler acknowledges that productivity is hard to measure in health care, and I don’t know how it’s done. Nevertheless, according to the figure, productivity growth in health, education, and social services was negative between 1995 and 2005, whereas the average across industries was 2.4%. This is not a good sign. To have any hope of obtaining a reasonable return on our massive health care (and other social program) spending, we need productivity in the sector to grow, not shrink. If the 1995-2005 trend continues, we risk both the health of our economy and populace.

Cutler’s paper explains why productivity and productivity growth are low in health care and what can be done about it. He hypothesizes why we see so little innovation in health care and suggests ways to promote it. It’s a familiar set of problems (asymmetric information, inability of plans and providers to capture long-term returns on short-term investments, plan turnover, third-party payment, etc.) and solutions (bundling, provider integration, pay-for-performance, etc.). He concludes,

To reduce this waste, organizational innovation will be required. To date, however, such innovation has been very rare in health care. This paper argues that lack of information and poor incentives are the key barriers to new organizational models, and accordingly that public action to address these issues is needed. Recent reform legislation has made changes in each of these areas. Whether the legislation addresses these problems sufficiently is something that only time will tell. (© 2010 by David M. Cutler.)

Actually, there are two levels of innovation required. We need innovation in the health care sector. But we don’t know for sure how best to foster it. So, we first need innovation in health policy. Doing nothing won’t suffice. Try we must.
