A surgical intern is a doctor in their first year of postgraduate training, known as PGY-1 (postgraduate year one), who has completed medical school and earned their MD or DO degree but is now learning surgery through hands-on hospital work. Despite the word “intern,” this person is a fully licensed physician, not a student. The internship year is the foundation of a surgical residency, focused on mastering the basics of pre- and post-operative patient care before taking on more independent surgical responsibilities in later years.
Where Interns Fit in the Hospital Hierarchy
Hospitals run on a layered training structure, and the surgical intern sits near the bottom of it. Above the intern is the senior resident (often called the “chief” on a given service), who oversees daily decision-making and leads the team during rounds. Above the senior resident is the attending surgeon, a fully trained physician who holds ultimate responsibility for every patient and every operation. Surgical interns receive indirect supervision from both senior residents and attending faculty, meaning they’re expected to carry out tasks independently but always have someone more experienced reviewing their work and available for questions.
Medical students also rotate through surgical services, and interns often serve as informal teachers for third- and fourth-year students doing their surgical clerkships. So even at the most junior level of the physician hierarchy, interns have a small educational role.
What a Surgical Intern Actually Does All Day
The bulk of an intern’s life is not spent in the operating room. Most of the day revolves around floor work: managing the patients on the surgical service before and after their operations. A typical day starts early, often around 5:00 or 5:30 a.m., when the intern gathers vital signs, fluid intake and output numbers, and overnight lab results for every patient on the service. By 6:00 a.m., team rounds begin. The chief or senior resident examines each patient alongside the intern, sets the plan for the day, and moves quickly to the next room.
After morning rounds, the intern spends hours executing that plan: placing orders for medications, imaging, and lab tests, checking that patients are on their home medications, reviewing new culture results or radiology reads, and following up on consultations from other services. Writing post-operative orders for patients coming out of surgery is a core task. Communicating directly with nurses about any non-standard orders helps prevent confusion and avoids unnecessary pages later.
Around 1:00 p.m., the intern pre-rounds again, updating vitals, labs, and imaging results that have come in since the morning. Afternoon rounds are a shift in dynamic: the intern typically leads these rounds rather than the senior resident, presenting each patient’s status and any changes. After afternoon rounds, the intern finishes remaining floor work, updates the signout sheet for the night team, and works toward getting patients discharged, ideally before 11:00 a.m. when possible. Documentation runs throughout the day. Every significant discussion, update, and consent for a procedure needs to be recorded. Discharge summaries must list every medication the patient is going home on, not just a vague shorthand.
Time in the Operating Room
When interns do get into the OR, they function as a first assistant or “surgeon junior” under direct supervision of an attending or senior resident. In practical terms, this means holding retractors to keep the surgical field visible, cutting sutures, and helping position or undrape the patient. On some cases, interns are allowed to make incisions, suture wounds closed, tie off blood vessels, or perform small amounts of dissection. What the intern gets to do varies significantly depending on the attending surgeon, the complexity of the procedure, and how far along the intern is in the year.
After the operation ends, the intern accompanies the patient to the recovery room and writes post-operative notes and orders. Senior residents often notice and appreciate an intern who anticipates this step and has the paperwork ready before being asked.
Work Hours and Call Shifts
Surgical internship is one of the most demanding years in all of medical training. The Accreditation Council for Graduate Medical Education (ACGME) caps resident work hours at 80 per week, averaged over four weeks. Overnight shifts were originally limited to 24 hours, with mandatory rest periods of at least 10 hours between shifts. In 2011, intern shifts were further capped at 16 hours, but that restriction was rolled back in 2017 after large trials found that the shorter shifts didn’t improve patient safety and sometimes disrupted continuity of care. Today, interns can work shifts longer than 16 hours and may stay beyond 24 hours if they choose to for patient continuity or important learning opportunities, though the 80-hour weekly average still applies.
Night call is a regular part of the schedule. ICU patients on the surgical service must be checked at least once overnight, not just when nurses call about a problem. The combination of early mornings, long OR cases, and overnight coverage means surgical interns routinely work 60 to 80 hours per week.
Categorical vs. Preliminary Internship
Not all surgical internships lead to the same destination. A categorical position means the intern has a guaranteed spot in a full general surgery residency, typically five years total, leading to board certification. A preliminary position offers only one to two years of surgical training and exists mainly as a stepping stone for doctors who plan to enter a different specialty afterward, such as anesthesiology, radiology, or ophthalmology, which require a year of broad clinical experience before their advanced training begins.
The day-to-day work looks similar for both types of interns. The difference is what happens next: categorical interns advance to PGY-2 in the same program, while preliminary interns move on to their advanced specialty match.
Skills Interns Are Expected to Develop
The ACGME tracks resident progress through a milestone system that spans the full length of residency. Milestones are organized into levels from 1 (expected of a brand-new resident) to 4 (the graduation target), covering medical knowledge, patient care, and professional competencies. An intern isn’t expected to reach Level 4. The goal for the first year is to move from Level 1 toward Level 2: demonstrating growing competence in evaluating surgical patients, understanding the care of critically ill patients, performing basic bedside procedures, and recognizing when to escalate a problem to a senior resident or attending.
By the end of intern year, a surgical trainee should be comfortable managing a floor full of post-operative patients, responding to common overnight emergencies, and assisting capably in the OR. The transition from someone who needs to be told what to do to someone who can anticipate what comes next is the central developmental arc of the year.
Compensation
Surgical interns are paid a fixed salary, not an hourly wage, which means the long hours translate to a modest per-hour rate. At Rutgers New Jersey Medical School, a representative academic program, PGY-1 salary is $70,660 for the 2024-2025 year and rises to $73,133 for 2025-2026. Most programs across the country fall in a similar range, roughly $60,000 to $75,000 depending on the institution and region. Benefits typically include health insurance and malpractice coverage. Given that many surgical interns carry six-figure medical school debt and work 70-plus hours a week, the effective hourly pay often works out to less than $20 per hour.
