Hip Replacements: Safest Hospitals, Safest Doctors, Ranked

ProPublica, an independent, non-profit newsroom that produces investigative journalism in the public interest, created a searchable web app which allows anyone to search the Medicare database for specific hospitals or doctors and then to see their complication rates per CMS (Centers for Medicare and Medicaid Services).

Additionally, the app ranks both the hospitals and physicians against their peers.

This data is okay, not great. There are many confounding reasons for any particular complication rate. There are patient specific issues. This data does not account for co-morbidities like obesity, diabetes, prior surgeries, heart disease and other diagnosis which are associated in the literature with higher rates of complications. Some physicians will not perform revision surgeries, so their complication rates will be lower.

This data should be treated as more interesting and entertaining than useful for actually selecting a care provider.

We know from our sister company PearlDiver Technologies, Inc. that the data coming from CMS has a lot of noise in it.

Here is how ProPublica described their methodology:

Our analysis is based on billing data hospitals submitted to Medicare from 2009-2013. We analyzed 2.3 million procedures: hip and knee replacements, three types of spinal fusion, gallbladder removals, prostate removals and prostate resections. ProPublica’s analysis accounted for factors such as patients’ health and age. We focused only on elective cases because they typically involve healthier patients with the best odds of a smooth recovery.

The ProPublica researchers found that the overall complication rates in the United States are low, ranging from 2% to 4%, depending on the type of surgery.

Furthermore, ProPublica found 756 surgeons in the data who each performed at least 50 operations and who did not record a single complication in the five years covered by the analysis. Another 1, 423 surgeons had only one.

If there is an obvious conclusion from this data, it is that U.S. surgeons are excellent and have very low complication rates.

So, for the ten largest metropolitan areas in the United States; here are the best of the best. We listed the five hospitals (as measured by the ProPublica data) in each metropolitan area and one surgeon at each hospital with the lowest complication rates.

*Occasionally, the same physician is listed at different hospitals but with the same CMS data. When that occurs, we selected the physician with the next lowest complication rate and designated this person with an asterisk.

Coming in future articles are the rankings for knee replacements, lumbar spine fusion posterior approach, lumbar spine fusion anterior approach and cervical spine fusion.
