The Cost of Thrift: Utilization of Imaging by Advanced Practice Clinicians

In his popular tome, Innovator’s Prescription, Clayton Christensen proposes several cures to healthcare’s cost disease, known as disruptive innovations. One is the replacement of physicians by advanced practice clinicians (APCs). That is by nurse practitioners and physician assistants. APCs meet the requirements for Christenson’s disruptive innovators: they cost less (than physicians) and are good enough. Read More
