As an RN for fifty years, I witnessed first hand how insurance companies gained more and more power and influence over doctors, hospitals, clinics etc. Many very dedicated and good holistic type doctors gave up their practices because of insurance companies interfering with the care the doctors wanted for their patients. Some Insurance companies would not pay unless a physician followed the insurance companies rules and algorithms. Patients sometimes suffered because they could not get the care they needed in a timely manner. Insurance providers would add more and more "rules" for doctors to follow including things like not covering a certain drug the doctor preferred over what the insurance provider felt was "necessary" and less expensive. Forcing doctors to discharge patients from hospitals early because the algorithms determined what the "usual" stay should be. All these things and more in my experience. 😠
