Health clinics at retail stores like CVS, Walgreens and Target are a popular choice for some families because of their convenience, but a leading medical society is advising parents to avoid the clinics for their children's care. The American Academy of Pediatrics (AAP) says such clinics are "detrimental" to the comprehensive, continuous care relationship between doctors and families, a concept known as the medical home. Such facilities should not be a source of primary care for children, the academy said.
