A residency program is a stage of graduate medical education that provides practical experience and technical skills required by trainees to become full-time doctors. It is a training environment where newly graduated MD or DO physicians go to begin specialized training to become a certain type of doctor. Residency programs take place after training has been completed at an Allopathic or Osteopathic Medical school and offer in-depth, practical training in a chosen medical specialty. The length of the residency program depends on the specialty chosen, and it takes place at a hospital or academic center. During the residency program, the resident will function and perform the duties of an attending doctor while being supervised. The first year of residency is known as the internship period, during which the resident will work under different departments and gain experience in multiple specialties. The resident will learn the intricacies of diagnosis and patient care, and will be given more responsibilities as their knowledge and skills grow. Some of the responsibilities of a medical resident involve performing continuous assessments of patients’ conditions, analyzing patient histories, and performing physical examinations.
