The Universal Protocol is a set of three mandatory steps designed to prevent wrong-site, wrong-procedure, and wrong-person surgery. Developed through expert consensus and enacted by The Joint Commission in July 2004, it applies to all accredited hospitals, ambulatory care centers, and office-based surgery facilities in the United States. The three steps are simple in concept: verify the patient and procedure beforehand, mark the surgical site, and pause for a formal “time-out” before the first incision.
Why the Protocol Exists
Operating on the wrong body part, performing the wrong procedure, or even operating on the wrong patient are events that should never happen, yet they still do. In 2024, The Joint Commission recorded 127 sentinel events classified as wrong surgeries, a 13% increase from the previous year. Of those, 68% involved the wrong site, 12% the wrong patient, 11% the wrong procedure, and 9% the wrong implant. These numbers only reflect events reported to The Joint Commission, so the true count is likely higher.
The Universal Protocol was created to build redundant safety checks into the process so that if one step fails, another catches the error before it reaches the patient.
Step 1: Pre-Procedure Verification
The first component is a structured verification process that begins well before the patient enters the operating room. Its purpose is to confirm three things: the patient’s identity, the planned procedure, and the exact surgical site. Every patient wears an identification bracelet listing their name, date of birth, and medical record number. The surgical consent form spells out the intended procedure and the name of the responsible surgeon, and it’s presented to the patient for confirmation.
A checklist guides the team through a review of all relevant documents, including a current history and physical exam and written informed consent. Staff check that every item is present, accurate, and complete before the patient is moved to the operating room. This is not a single moment but an ongoing process. Verification can happen at the time of scheduling, at admission, and again at the door of the procedure room, each checkpoint reinforcing the last.
Step 2: Marking the Surgical Site
The second component requires someone to physically mark the spot on the patient’s body where the procedure will take place. The rules around this step are deliberately specific to prevent ambiguity.
- Who marks: The person performing the procedure is responsible for making the mark. This is not delegated to a nurse or assistant.
- What the mark looks like: It must be unambiguous. Acceptable marks include the surgeon’s initials, the word “YES,” or a line representing the proposed incision. An “X” is discouraged because it could be interpreted as “not here.”
- Where it goes: The mark is placed at or near the incision site. Non-operative sites should not be marked unless needed for another aspect of care.
- Visibility: The mark must remain visible after the skin is cleaned and sterile drapes are placed over the patient. It’s made with a permanent marker, not an adhesive sticker alone.
- Patient involvement: Whenever possible, marking takes place while the patient is awake and aware, giving them a final opportunity to confirm the correct location.
Every facility is expected to use a consistent marking method throughout its organization so there’s no confusion between departments or surgical teams.
Step 3: The Time-Out
The time-out is the final safety net. It happens in the procedure room, immediately before the first incision, and it requires every member of the team to stop what they’re doing and participate. The surgeon, anesthesia provider, and nurse all take part.
During the time-out, the team verbally confirms the patient’s name, the planned procedure, and the location of the incision. Team members also introduce themselves by name and role, which may sound trivial but serves a real purpose: it flattens the hierarchy in the room and makes it easier for anyone, regardless of title, to speak up if something seems wrong. No cutting, no draping, no other activity continues until the team reaches unanimous agreement that they have the right patient, the right procedure, and the right site.
Where the Protocol Applies
Although the Universal Protocol was created with surgery in mind, its principles extend beyond the traditional operating room. The Joint Commission frames the requirements under codes that apply broadly to invasive procedures. Facilities adapt the protocol for settings like interventional radiology suites, endoscopy labs, cardiac catheterization labs, and other areas where laterality or site selection could lead to error. The core logic is the same: if a procedure involves an incision, an insertion, or a choice between left and right, the three steps apply.
Why Compliance Remains a Challenge
The Universal Protocol has been in place for over two decades, and it has measurably improved teamwork and reduced the overall risk of wrong-site surgery. Yet compliance is inconsistent. Several recurring barriers explain why.
Staff working in high-volume operating rooms sometimes view the checklist as an unnecessary interruption to an already streamlined routine, particularly when case turnover is rapid and teams feel overburdened. During urgent or emergent surgeries, there is often reluctance to follow all 19 items on associated safety checklists when every minute feels critical. Some providers worry that running through the checklist aloud could make the patient anxious, especially if a gap in preparation is revealed in front of them.
The deeper issue is accountability. The protocol only works when every team member actively participates rather than passively standing by while one person reads through a list. When the time-out becomes a rote recitation that no one is truly listening to, its protective value erodes. Facilities that treat the Universal Protocol as a genuine team exercise rather than a bureaucratic formality tend to see better results.
The Patient’s Role
If you’re heading into a procedure, you are part of the Universal Protocol whether you realize it or not. You’ll be asked to confirm your name, date of birth, and what procedure you’re having, possibly multiple times by different people. This repetition is intentional. You may also be asked to point to or confirm the surgical site before it’s marked. If anything sounds wrong during these checks, say so immediately. The system is designed with the expectation that patients are a final line of defense against errors that slip past paperwork and checklists.
