One of the main benefits of immediate care is that patients do not require an appointment in order to be seen by a doctor or trained medical professional. Immediate care centers operate on a walk-in basis so that patients are seen, treated, and sent on their way quickly and efficiently. Through an immediate care center, patients will still receive top medical care, without the extended time spent in a waiting room or having to wait several days to get an available appointment with their family doctor. Some immediate care centers may offer appointments for patients who do want to have a confirmed time so they can make their visit as quick as possible, however, an appointment is not required. Illnesses and injuries can happen at any time, without warning, and immediate care gives people an option for receiving medical attention when these instances happen.
