NEW YORK (Reuters Health) - Even children who have pediatricians sometimes get care from retail medical clinics like the ones in large drugstore chains, according to a survey of parents near St. Louis. Almost a quarter of the parents surveyed while at a pediatrician's office had taken their children to retail health clinics, many saying they found it more convenient than going to their child's regular doctor. Retail health clinics, which are often found in the pharmacy sections of chain stores such as CVS, Walgreens or Target, are usually staffed by nurse practitioners or physician assistants and are able to provide care for a number of common illnesses, like colds.
