The short answer
Your credentials get you in the door. Your first day decides how the team works with you.
An OR team has reviewed your CV and your privileges, but nobody in that room has watched you operate. In a new hospital, trust is earned again, in hours, by how you prepare, how you treat people and how predictable you are when the case starts.
I have operated in 15 different hospitals as a locum cardiothoracic surgeon. What I took from that is simple: “Walking into a brand new facility and commanding that authority and respect is a skill set.” It can be learned, and it starts before you scrub.

Trust starts before you walk into the OR
The surgeon who spends the night before the first case finding parking, the after-hours entrance and the medical staff office is spending attention that belongs to patients. Arrive at least a day early if you can. Drive the route. Know which entrance you will use at 5 a.m. and who to ask for at medical staff services.
On the first morning, get to the medical staff office before clinical duties begin. Pick up your badge, confirm your active privileges and procedural authorizations in writing, get your EMR access working and finish required orientation. A team notices the surgeon who is ready when the room is ready.
Introduce yourself to the people who run the room
Make a short list and meet them on day one: the OR manager or unit director, the anesthesia lead, the perfusion lead, the ICU charge nurse and the scrub tech leads. Learn their names and use them.
Then ask the charge nurse or OR coordinator for a short practical tour: the OR suites and supply rooms, the ICU, the blood bank, pharmacy and dispensing stations, and the doctors’ lounge. Experienced staff know where everything is, and most are glad to show you if you ask directly and respectfully.
These introductions are not courtesy alone. They are how you learn who to call when the plan changes at 2 a.m.
Ask how they do it here before you say how you do it
Every hospital has its own equipment, routines and unwritten rules. I sometimes describe the adjustment this way: you have to be able to drive a Ford down the street instead of demanding a Mercedes every time you operate.
The point is not to accept less. The point is to separate preference from requirement. Be flexible about unfamiliar processes, instrument trays and workflows. Ask how the team usually handles a step before you propose your own way. People cooperate faster with a surgeon who learned their system first.
Make the first case calm and predictable
Your first case is the one the team will talk about. Choose clarity over speed. Walk through the plan with anesthesia, perfusion and nursing before the patient is in the room. Follow the facility’s own briefing and time-out process exactly as written.
Keep your communication even. State what you need before you need it. If something is unfamiliar to you, ask a precise question rather than guessing. A calm, well-briefed first case does more for your standing than any line on your CV.
Leave the label at the door
On my first locum assignment, a nurse called me “the new locums,” and my ego answered before my judgment did. I tell that story in Why I Chose Locum Tenens. The lesson for day one is that your title from your old hospital does not travel with you. Your judgment, preparation and manners do.
Authority in a new OR is earned by being useful: knowing the case, knowing your boundaries, keeping your word and treating every member of the team as part of the work. When you do that consistently, the label stops mattering to you and to them.
Speak up early when something essential is missing
Adaptability does not mean lowering your standards. You also have to be willing to say, this isn’t safe. If the support you need is not there, whether that is perfusion, cardiac anesthesia, specialized nursing or ICU coverage, name it before the case, and discuss with the team what needs to change.
Raising a safety concern early, in plain words and through the right people, builds trust. Teams remember the surgeon who protected the patient and the team from a preventable problem.
Let the trust you earn travel with you
The most valuable asset a locum surgeon builds is a small group of OR leaders, anesthesiologists, chiefs and nurse managers who will vouch for you when someone asks if they know a reliable surgeon.
Before you leave an assignment, ask one or two of them for two or three sentences about what it was like to work with you, especially reliability and how you fit with the team. Keep a current reference list across different hospitals and roles. That record makes the next team’s first day with you easier.
Questions from the field
Frequently asked questions
How long does it take a locum surgeon to earn a new team’s trust?
There is no fixed timeline. It depends on the team, the case mix and the length of the assignment. Preparation, clear communication and a calm, predictable first case shorten it, and a careless first day can lengthen it for the rest of the assignment.
Should a locum surgeon change how an unfamiliar OR runs?
Learn the local routine first. Be flexible about preferences such as equipment or workflow, and firm only about what safe care requires. If something essential is missing, raise it before the case through the OR manager or the appropriate clinical lead.
Who should a locum surgeon meet on the first day?
Start with the OR manager or unit director, the anesthesia and perfusion leads, the ICU charge nurse and the scrub tech leads, plus the medical staff office and anyone named as your go-to contact for problems. Learn their names and how to reach them after hours.
What if the team is skeptical of locum surgeons?
Do not argue about the label. Let your preparation, your communication and your care for each patient answer it. Teams judge a surgeon by the work they see, and a skeptical first impression often changes after one well-run case.
