Goodbye, doctor's office. Hello, Walmart? Based on Walmart's latest moves, it's not as unlikely as it sounds. After years of "Will they or won't they?" discussion, Walmart is making its long-awaited move into delivering primary care: The retailer has quietly opened a half-dozen primary care clinics across South Carolina and Texas, and plans to launch six more before January. The clinics will be staffed by nurse practitioners, in a partnership with QuadMed. Walmart watchers know that the company already has more than 100 "retail clinics" across its stores, a strategy it's pursued for years. So why fuss over a handful of new clinics?
