Could It Be That Patients Aren’t Any Safer?

On the occasion of last year’s tenth anniversary of the IOM Report on medical mistakes, I was asked one question far more than any other: after all this effort, are patients any safer today than they were a decade ago?

Basing my answer more on gestalt than hard data, I gave our patient safety efforts a grade of B-, up a smidge from C+ five years earlier. Some commentators found that far too generous, blasting the safety field for the absence of measurable progress, their arguments bolstered by “data” demonstrating static or even increasing numbers of adverse events. I largely swatted that one away, noting that metrics such as self-reported incidents or patient safety indicators drawn from billing data were deeply flawed. Just look at all the new safety-oriented activity in the average U.S. hospital, I asked. How could we not be making patients safer?

I may have been overly charitable. This week, in an echo of the Harvard Medical Practice Study (the source of the 44,000-98,000 deaths/year from medical mistakes estimate, which launched the safety movement), a different group of Harvard investigators, led by pediatric hospitalist and work-hours guru Chris Landrigan, published a depressing study in the New England Journal of Medicine. The study used the Institute for Healthcare Improvement’s Global Trigger Tool, which looks for signals that an error or adverse event may have occurred, such as the use of an antidote for an overdose of narcotics or blood thinners. Following each trigger, a detailed chart review is performed to confirm the presence of an error, and to assess the degree of patient harm and the level of preventability. While the tool isn’t perfect, prior studies (such as this and this) have shown that it is a reasonably accurate way to search for errors and harm – better than voluntary reports by providers, malpractice cases, or methods that rely on administrative data.
