This is an interesting study. Men and women are different. We tend to forget that in this pseudo-post-equality world we live in. We forget that equality isn't something that's intrinsic to humanity, but rather it's a social construction we artificially impose upon biological reality:

It is important that this study is limited to elderly patients. It does use a lot of data though from many doctors and physicians, but only over the course of a 30 day window.

I'd like to see studies that do this with younger patients as well, as well as studies done over a longer timespam. If the same percentage present themselves, it be interesting to see if there was some kind of training or something that could be added to the medschool/education process to help male physicians implement the natural practices used by the female physicians to reduce the overall mortality rates.

If studies on younger patients or longer timespans show the percentages converging down to zero, than maybe this study was an isolated result from 30 days in that one facility and the differences aren't really statically significant. Studies like this really need to be reproduced.
