According to a Walmart spokesperson, Walmart foresees opening more than 6,000 in-store medical clinics over the next five (5) years.  Walmart already has 75 clinics in 12 states and envisions that the clinics could serve as the basis for a national electronic medical record platform.  The clinics, which will likely accept walk-in patients and have extended hours, will almost certainly present a new and unique challange to existing primary care practices in Walmart’s markets.
