Lede section and definition 

The lede section I see had been changed to say that a health care system is the some total of all the health care facilities.  This is not the definition of health care system but could also be the definition of a health care hotch-potch that is not a system at all. Systems are interconnected and work together in a way that is designed for maximum efficiency. The sum total of what there is may be a system if it has been designed that way or has emerged to be integrated into a whole functioning system. But a collection of what there is does not make it a system.
