Walk-in clinic

A walk-in clinic (also known as a walk-in centre) is a medical facility that accepts patients on a walk-in basis and with no appointment required. A number of healthcare service providers fall under the walk-in clinic umbrella including urgent care centers, retail clinics and even many free clinics or community health clinics. Walk-in clinics offer the advantages of being accessible and often inexpensive. It is estimated that there are nearly 11,000 walk-in clinics in America, although it is impossible to calculate an exact number given the variable and ill-defined nature of the category. Urgent care centers make up the largest percentage of walk-in clinics in America with an estimated 9,000 locations nationwide. In fact, consumers often erroneously refer to all walk-in clinics as urgent care centers, and vice versa. Retail clinics are the next most prevalent in the industry with 1,443 locations as of July 1, 2013.

Walk-in clinics are often not staffed by physicians but nurses, and so are unable to treat the same range of conditions as regular doctors and hospitals. Other disadvantages may include the urgency to make the patient's visit as quick as possible in order to reduce the long waiting list of walk-ins at the clinic, which may fail to fulfill the purpose of the visit.
