Summary of article from D Magazine, by Will Maddox:
Walmart, Amazon, and other major corporations have struggled to make a profitable venture into primary care, often citing high operating costs and reimbursement challenges. Retail healthcare has proven complex due to the transient nature of providers in these settings and the difficulty in maintaining long-term patient relationships. Further, the current fee-for-service model in healthcare is unsustainable. The ongoing shortage of physicians is a significant challenge. A new payment model could alleviate the shortage and better meet the growing demand for primary care.
