With rising health care costs, retail clinics, typically staffed by nurse practitioners, have increased in popularity (about 6 million visitors in 2009) due to easier access. These clinics are usually located in convenient locations and patients can visit these clinics after hours. Most importantly, these retail clinics are significantly cheaper than regular primary care physician visits. Most patients visit these clinics for simple acute conditions and these clinics are usually appropriate (and cost efficient) for diagnosing these ailments rather than visiting larger hospitals. Interestingly, a new RAND study of health insurance records, finds that these retail clinic visits reduce visiting primary care for subsequent acute new conditions by about 27% and that continuity of care is hampered leaving some health experts worried.
