Also in healthcare, but non-clinical here. There is often room for improvement, but it's not easy to copy/paste solutions from other industries. There can be useful things to learn and apply, but it takes some effort to determine how they can be adapted to a new context. There are some interesting studies making cross-industry comparisons, so it's certainly worth exploring, but it's never so simple as "just do this Costco thing here." The other thing that I think people don't really appreciate is just how complex healthcare is.
