How much does it matter which hospital you go to? Of course, it matters a lot – hospitals vary enormously on quality of care, and choosing the right hospital can mean the difference between life and death. The problem is that it’s hard for most people to know how to choose. Useful data on patient outcomes remain hard to find, and even though Medicare provides data on patient mortality for select conditions on their Hospital Compare website, those mortality rates are calculated and reported in ways that make nearly every hospital look average.
Some people select to receive their care at teaching hospitals. Studies in the 1990s and early 2000s found that teaching hospitals performed better, but there was also evidence that they were more expensive. As “quality” metrics exploded, teaching hospitals often found themselves on the wrong end of the performance stick with more hospital-acquired conditions and more readmissions. In nearly every national pay-for-performance scheme, they seemed to be doing worse than average, not better. In an era focused on high-value care, the narrative has increasingly become that teaching hospitals are not any better – just more expensive.
But is this true? On the one measure that matters most to patients when it comes to hospital care – whether you live or die – are teaching hospitals truly no better or possibly worse? About a year ago, that was the conversation I had with a brilliant junior colleague, Laura Burke. When we scoured the literature, we found that there had been no recent, broad-based examination of patient outcomes at teaching versus non-teaching hospitals. So we decided to take this on.
One of the main goals of the Affordable Care Act (ACA), perhaps second only to improving access, was to improve the quality of care in our health system. Now several years out, we are at a point where we can ask some difficult questions as they relate to value and equity. Did the ACA improve quality of care in the ways it intended to? Did it do so for some people, or hospitals, more than others?
