ASC Survey Readiness: What Surveyors Look For
Preparing for an ASC survey doesn't start when a survey is announced. By the time a surveyor is on site, there's little opportunity to correct gaps in documentation, medication management, or staff training. The centers that perform well during surveys aren't necessarily the ones that spend the most time preparing the week before. They're the ones that make survey readiness part of everyday operations.
The good news is that survey findings tend to center around the same areas. Once you understand where surveyors focus and why those areas commonly generate findings, it's much easier to identify potential gaps before they become problems.
The sections below highlight the areas surveyors review most, along with practical ways to strengthen your survey readiness year-round. If you're looking for a more detailed, line-by-line review, you can download our ASC Survey Readiness Checklist at the end of this article.
Controlled Substance Documentation
Controlled substance documentation generates more findings than any other category in ASC surveys. It's rarely about intentional wrongdoing. It's about how much can go unnoticed in a manual, paper-based system until someone finally checks.
Surveyors typically want to see:
Complete logs with accurate, continuous running totals and no missing entries
A witness signature on every waste and disposal transaction
Daily counts, completed and witnessed, for at least the past 30 days
A written explanation for every count discrepancy, not just a note that one occurred
Two full years of records that can be retrieved on request
Storage secured to a wall or floor
An access list that reflects who's currently employed and authorized
A current DEA registration, with Form 106 filed for any reported theft or loss
At the core, surveyors are checking whether a facility can account for every controlled substance transaction, going back two years, without gaps. Even a single missed signature can prompt additional questions and closer review. Several similar gaps suggest a pattern, and that's what tends to lead to a citation.
This is also where the operational case for moving off paper logs is strongest. Manual tracking depends on someone remembering to sign, log, and reconcile every transaction correctly, every time. A digital system removes that dependency: transactions are recorded automatically, discrepancies are flagged right away, and two years of records are already organized instead of needing to be reconstructed under pressure. Facilities that make this shift often see improved documentation accuracy, along with real-time savings during counts and reconciliation.
Medication Management and Storage
Beyond the controlled substance cabinet, surveyors look at documented temperature monitoring for storage areas, timely removal of expired medications, and clear separation between medications and non-medication supplies.
A few specifics worth checking regularly, not just before a survey:
Multi-dose vials should show both an opened date and an expiration date, every time
Emergency medications should be current and easy for staff to reach quickly, not just stored somewhere they're technically available
High-alert medications should be physically separated from routine stock
Medication reconciliation should be a consistent, documented practice, not just a written policy that's rarely revisited
Surveyors often ask staff to walk through the reconciliation process directly, rather than relying on the policy document alone. If your team can demonstrate the process confidently and consistently, that's a good sign your daily practice matches your policy.
Documentation and Record Keeping
This category covers the paperwork most centers assume is already in order: complete patient records for the review period, signed informed consent, anesthesia records with pre- and post-operative assessments, signed and dated physician orders, documented adverse events, current quality improvement data, and up-to-date staff credentials.
One detail that's easy to miss: policies and procedures need to be reviewed, updated, and formally acknowledged by staff within your required timeframes. A policy that was updated but never re-acknowledged is, from a survey standpoint, treated much like one that was never reviewed.
Complete records matter beyond the survey itself. They support patient care, strengthen compliance, and make it easier to respond when questions come up. When documentation is maintained consistently throughout the year, survey readiness becomes part of everyday operations instead of a last-minute project.
Infection Prevention and Safety
This section tends to be more straightforward than others: sterilization and disinfection logs, biological indicator results, hand hygiene monitoring, proper sharps disposal, accessible PPE, and current fire safety inspections either exist and are current, or they don't.
One area worth double-checking: single-use item reprocessing. It's uncommon, but surveyors treat any indication of it as a serious finding rather than a documentation gap. If your facility has any practice that resembles reprocessing single-use items, it's worth resolving well before survey day.
Staff Competency and Training
Training records show what your center requires. Staff interviews show what your team actually knows and can apply.
A center can have complete training files, including annual training, documented diversion prevention training, and current BLS and ACLS certifications, and still run into trouble if a surveyor asks a staff member to explain how they'd report a suspected diversion incident. Staff should be able to answer clearly, without needing to check a reference first.
It's worth testing this internally before a surveyor does. Ask a few staff members the question directly and see how confidently they answer.
Physical Environment
This category includes equipment and safety standards in OR and procedure rooms, medical gas system inspections, electrical safety checks, and temperature and humidity logs for clinical areas. It also includes keeping controlled substance storage areas free of unauthorized access points and posting clear signage for restricted areas.
Most of this fits naturally into routine facility maintenance rather than requiring separate pre-survey attention. Building these checks into a regular maintenance schedule keeps them from becoming a last-minute task.
Preparing for Survey Day Itself
Strong documentation and a well-trained staff can still lose points to disorganization on the day itself. A few practices help:
Designate one staff member as the surveyor escort and brief them on their role ahead of time
Brief the full team on survey expectations, including answering questions honestly and directly
Pull and organize two years of controlled substance logs in advance
Confirm every department head knows exactly where their documentation lives
Walk through all clinical and storage areas the day before
Confirm emergency equipment is stocked, accessible, and documented
Remove anything expired, outdated, or incomplete from circulation ahead of time
Survey Readiness Works Best as a Daily Habit
The centers that handle surveys well tend to share one thing in common: they don't treat readiness as something that starts when a survey is announced. It's part of how the center already runs, which also tends to mean less scrambling, less overtime, and less time pulled away from patient care when a survey does come up.
Controlled substance documentation will likely keep generating the most findings, simply because it depends on people completing the same manual task correctly, every time, for years without a miss. A digital system takes on that responsibility instead, recording transactions as they happen and flagging discrepancies immediately. That's the shift MedServe helps ASCs make: less time spent reconstructing records under pressure, and more time available for the work that matters most.
