1) Feverent, almost religious, adherence to hand washing. 2) No neck ties or dangly sleves whatsoever in buildings that house patients. 3) Change from stainless steel hardware for doors and travel touch surfaces back to "brass/copper".

Those are simple, virtually free, things that have a very meaningful impact on outcomes. Some of the most viscous fights I've had with hospital boards were over what amounted to the "uglier look" of copper/brass.

It is an extremely unpopular topic in healthcare but the area that takes a lot of effort to solve but also has a tremendously out-weighted benefit is reducing preventable medical errors. My opinion after being in healthcare ~20 years is that preventable medical error is absolutely in the top 3 causes of death in the US. The easiest subset of it to resolve is prescription related errors, we have all the tools to resolve those but not the will.
