The outpatient department is the first intermediary between a patient and the hospital staff. A patient first comes to the OPD for inspection and then the doctors from the OPD refer him/her to the respective departments of treatment according to the patient needs. Hospitals have OPDs for providing attention to the patients and conducting medical treatment. The minor treatments can be easily conducted in the OPDs. It is not necessary to admit a patient to the hospital for surgeries and treatment. Moreover, modern OPDs have the necessary equipment and facilities to conduct surgeries, medical tests, and diagnoses.
