Much of it stems from regulatory bodies. The staggering amount of hoops that need to be jumped through for reimbursement/accreditation/etc. needs vast numbers of non-clinical people to service those hoops. Also, vast numbers of people are needed to constantly maintain and update the electronic medical record. Coding, billing, all that shit adds up quickly and then you throw in the expansion into health systems instead of stand alone hospitals and clinics and people are needed to oversee affiliates etc to make sure everyone is in line. Expansion brings about branding and advertising and here we are, the majority of employees have nothing to do with direct patient care. It's all about the business. We've lost our way.
