The call comes and your stomach drops. The survey team is on its way.
If you have been in infection prevention for any length of time, you know that feeling. Whether it is The Joint Commission (TJC) or DNV Healthcare conducting the review, an accreditation survey is not just an audit. It is a full examination of your infection prevention program, your documentation, your staff knowledge, your physical environment, and your ability to demonstrate that what you have on paper actually happens at the bedside.
The good news is that surveyors are not trying to catch you. They are trying to confirm that your patients are safe. When you approach a survey from that frame, the preparation becomes clearer.
This article walks you through what TJC and DNV are actually looking for in infection control, the citations that come up most often, and the preparation strategies that experienced IPs use to walk into survey week with confidence.
TJC vs. DNV: What Is the Difference?
Both TJC and DNV are CMS-deemed accreditation bodies, which means accreditation by either organization satisfies the Medicare Conditions of Participation. The choice between them is a leadership and organizational decision, not a quality decision. Both hold facilities to rigorous standards.
The Joint Commission uses a tracer methodology. Surveyors follow individual patients through the care continuum, from admission through discharge, looking for evidence that standards were met at every handoff and intervention. For infection prevention, this means they may trace a CAUTI patient and examine every touchpoint: insertion documentation, maintenance bundle compliance, nursing education, and your surveillance data.
DNV Healthcare integrates ISO 9001 quality management principles into its accreditation process. Surveyors look not just at whether you are meeting standards, but whether you have a functioning quality management system that continuously identifies and improves gaps. For IPs, this means your QAPI documentation, your trending data, and your corrective action plans carry significant weight.
In practice, both surveys will examine the same core infection prevention elements. The framing is different. The expectations are equivalent.
What Surveyors Are Actually Looking For in Infection Control
Regardless of which body is conducting your survey, infection control reviewers focus on the same domains.
1. Infection Prevention Program Structure
Surveyors want to confirm that your facility has a functioning, documented infection prevention program. This includes:
- A designated infection preventionist with appropriate training and credentials
- An active Infection Control Committee or equivalent governance structure
- A written infection prevention plan that is reviewed and updated at least annually
- Clearly defined surveillance priorities that are risk-stratified for your patient population
The credentials question matters more than many IPs realize. CIC certification is not universally required, but it is recognized by both TJC and DNV as evidence of professional competency. When a surveyor asks about your qualifications, your answer needs to be confident and documented.
2. Surveillance Data and Trending
This is where many programs get cited. Surveyors do not just want to see that you are collecting data. They want to see that you are using it.
Specifically, they look for:
- NHSN enrollment and timely data submission for applicable events (CAUTI, CLABSI, SSI, CDI, MRSA)
- Facility-wide SIR trends over time
- Evidence that surveillance findings are being reported to leadership and clinical staff
- Corrective actions that are tied to surveillance findings, not just policy updates
If your SIR is above 1.0 and you cannot explain what you are doing about it, that is a problem. If your SIR is below 1.0 and you can show the interventions that drove it there, that is exactly what surveyors want to see.
3. Hand Hygiene Program
Hand hygiene remains the single most consistently cited infection control finding across both TJC and DNV surveys. It is not because facilities do not have a hand hygiene policy. It is because observed compliance and documented compliance frequently do not match.
Surveyors will observe hand hygiene during tracers. They will ask staff about the moments for hand hygiene. They will review your compliance monitoring data and ask what happens when compliance falls below your threshold.
Your program needs:
- A defined compliance monitoring process with documented observations
- A threshold for acceptable compliance (most programs set 90% or above)
- Evidence of feedback to unit leadership and staff
- A clear escalation pathway when compliance drops
4. Isolation and Transmission-Based Precautions
Surveyors observe whether isolation precautions are being implemented correctly, not just whether the policy exists. Common findings include:
- Isolation carts that are improperly stocked or positioned
- Staff donning or doffing PPE incorrectly while being observed
- Signage that is inconsistent, missing, or unclear
- Patients in transmission-based precautions without documented clinical rationale in the chart
- Inconsistent N95 fit testing records
Know your isolation census going into survey week. Know which patients are on what precautions and why. If a surveyor traces one of those patients, you want to be able to speak to the clinical decision-making.
5. Environment of Care and High-Risk Areas
Surveyors walk the environment. They open equipment storage rooms. They look at endoscope reprocessing areas. They visit the sterile processing department. They check surgical suites for traffic patterns and attire compliance.
The areas that generate the most infection control findings during environmental rounds include:
- Improper storage of sterile supplies (expired items, open packages, stored below the splash zone)
- Endoscope reprocessing documentation gaps (Spaulding classification compliance, high-level disinfection logs, drying and storage)
- Hand hygiene product availability (dispensers that are empty, broken, or inaccessible)
- Single-use device reuse without approved reprocessing protocols
- Medication storage and multi-dose vial labeling
If your facility has a sterile processing department, strongly consider a dedicated walk-through with your SPD manager at least four to six weeks before any anticipated survey window.
6. Staff Education and Competency
Surveyors will ask staff questions. Not just nurses. Environmental services, dietary staff, and volunteers are all fair game. The questions are typically straightforward but the answers reveal the depth of your education program.
Common staff questions during infection control tracers include:
- When do you perform hand hygiene?
- What do you do if you have a needlestick?
- How do you know if a patient is in isolation?
- What PPE do you put on before entering that room and in what order?
Documented competency assessments for high-risk tasks (N95 use, isolation precautions, central line care) should be current for all applicable staff.
The Citations That Come Up Most Often
Based on patterns in TJC and DNV findings data, the infection control citations that appear most consistently are:
- Hand hygiene monitoring -- incomplete or infrequent observations, no evidence of feedback loop
- Isolation precaution implementation -- observed gaps in donning and doffing
- Infection control data reporting -- surveillance data not consistently presented to leadership
- Environment of care -- expired supplies, improper storage, reprocessing documentation gaps
- Staff education -- competencies not current, no evidence of post-education follow-up
None of these are surprising. All of them are preventable with consistent program management. The challenge is that infection preventionists are typically covering large facilities with limited support. Things slip. The goal of survey preparation is to systematically surface those gaps before the survey team does.
A Practical Preparation Timeline
Six to Eight Weeks Before Survey
- Review your infection prevention plan for currency. Update any policy that references outdated guidelines.
- Pull your NHSN data and review SIRs for all device-associated and procedure-associated events. Flag any above 1.0 and document your corrective actions.
- Conduct a comprehensive environment of care walkthrough in all high-risk areas: sterile processing, endoscopy, the OR, and any construction or renovation zones.
- Audit isolation precaution carts in your highest-volume units.
- Review N95 fit testing records for currency.
Four Weeks Before Survey
- Run a mock tracer on your highest-complexity patients. Include a CAUTI patient, a CLABSI patient if applicable, and a patient on transmission-based precautions.
- Present a summary of your surveillance data to your Infection Control Committee and document the meeting.
- Brief your unit managers on the most common surveyor questions so they can reinforce with their teams.
- Audit hand hygiene compliance data for the past two quarters. If compliance is below threshold, document your intervention.
One to Two Weeks Before Survey
- Refresh signage in isolation areas. Replace anything that is faded, torn, or inconsistent.
- Restock isolation carts to full capacity.
- Verify that all high-risk area staff have current competency documentation on file.
- Review your corrective action logs. Every finding from your internal audits should have a documented response.
The Day Surveyors Arrive
- Know your current isolation census. Have the list accessible.
- Brief your nursing supervisors and charge nurses that the survey has begun.
- Be available. Surveyors will have questions for the IP.
- Stay calm. You have done the work. The survey is the verification.
One Thing Most IPs Overlook
Documentation of your own work.
Infection preventionists often focus heavily on clinical compliance and overlook the paper trail of their own program management activity. Surveyors want to see that you are functioning as a program, not just as an individual practitioner responding to incidents.
That means dated committee minutes, dated surveillance reports, dated corrective action plans, dated competency assessments, and dated policy reviews. When a surveyor asks "how do you know your program is working?" your answer should be a documented trend over time, not a verbal summary of what you remember doing.
How Prevexium Supports Survey Readiness
Inspectus, Prevexium's environment of care audit tool, was built specifically for this kind of preparation. The 31-point rounds template walks you through the high-risk areas surveyors examine, auto-scores your compliance against a 90% benchmark, and generates a gap-driven action plan so you know exactly where to focus your limited preparation time.
You do not have to rebuild your audit tool from scratch before every survey window. The template is already calibrated to the areas that generate the most findings. Run it. Review the gaps. Address them. Document the follow-up. That is the cycle.
Prevexia AI can help you cross-reference current CDC, WHO, and CMS guidance when you need to verify that your policies reflect the most current evidence base. Surveyors notice when your policies cite outdated guidelines. Staying current is a continuous responsibility, not a pre-survey scramble.
The Bottom Line
No survey is without stress. But the facilities that consistently perform well on infection control reviews share a common characteristic: they do not prepare for surveys. They run their infection prevention program the way the survey expects it to be run all year long.
Consistent surveillance. Consistent monitoring. Consistent education. Consistent documentation.
When that is your baseline, the survey is not an event to survive. It is an opportunity to demonstrate the work you have already done.
