Since the first one opened in 2000, retail medical clinics, such as those set up in grocery stores and pharmacies, have become increasingly widespread. There are currently about 1,200 of these in-store clinics in the United States, and more than 6,000 are expected to open across the country within five years. Typically staffed by nurse practitioners, these clinics offer care for minor illnesses, including coughs, body aches, and itchy eyes; perform routine exams, like college and camp physicals, and vaccinations; as well as providing diabetes and cholesterol screening.
