receive prescription drugs for free or at a greatly reduced cost. Many free clinics work to qualify patients on behalf of these programs. In some cases the clinic receive and then distribute the medications themselves, in others they verify that the patient is eligible for the program, and the medication is then shipped to the patient, or patient receives the medication from a local pharmacy. Some free clinics sole mission is to help those who do not have prescription drug coverage, and cannot afford for their medications, to enroll in prescription assistance programs. Such clinics are known as "clinics without walls" because they dispense with the need to have their own building, exam rooms, or clinical equipment. Dentistry Some free clinics are able to assist with dental problems. This is handled either at the clinic itself, if the clinic has its own dental facilities and a dentist; or it is facilitated through a partnership with one or more local dentist who are willing to take referred patients for free. For example, a clinic might have ten local dentists who will each accept two patients per month, so this allows the clinic to treat a total of twenty dental patients each month. Some clinics use a referral system to handle other forms of specialized medical care. Student-run clinics Student-run clinics (SRC) are an increasingly prevalent part of U.S. medical school curricula, and they are designed to improve health-care delivery to underserved populations. The vast majority of these clinics are free-of-charge and they have been shown to result in high patient satisfaction The preventive medicine interventions offered at this clinics have been proved to have significantly high health and economic impacts. Free clinics allow student volunteers to become more socially aware and culturally competent in their medical experience. Medical schools sometimes do not address social determinants of health or treatment of underserved populations, and medical students can use free clinic volunteering to learn about these issues. At free clinics, medical student volunteers learn to listen to the full history of their patients and treat them as a whole rather than a list of symptoms. Medical students balance the power dynamic between the patient and provider, acting as a patient advocate. Furthermore, students who are exposed to SRCs are more likely than their peers to continue to work with underserved populations after graduation.
