Surgery centers are paying more for less anesthesia coverage. Perioperative nurses are the ones rebuilding the schedule when it falls through.
The surgeon is scrubbed in, the patient is prepped and the room is turned over. Then the anesthesia provider is pulled to cover another site, and the day starts coming apart.
That scene is becoming routine. Trade coverage this week, including a string of Becker’s ASC Review stories on Medicaid anesthesia rates and on how rural facilities have long coped with thin coverage, has framed the anesthesia shortage as a reimbursement fight between surgery centers, anesthesia groups and payers. For perioperative nurses, it is something more immediate: a daily scheduling problem that lands on their shift.
A gap that is getting wider
The national numbers explain why the pressure is not easing. The National Center for Health Workforce Analysis projects a shortfall of 3,720 full-time-equivalent anesthesiologists in 2026, widening to 8,140 by 2031, according to an August 2026 analysis from Medicus Healthcare Solutions. The same projections show metropolitan areas short about 3,140 CRNAs this year.
The pipeline is slow to respond. Since 2025, all new CRNAs must hold a doctoral degree, which stretched training from roughly 28 months to between 36 and 51 months. Demand keeps climbing: surgical volume is expected to grow 2% to 3% a year over the next decade as the population ages.
Rural facilities feel it first. More than 80% of rural U.S. counties have no anesthesiologist, and CRNAs provide much of the anesthesia care in those communities. A facility with one or two anesthesia providers can lose surgical services entirely when one leaves.
Where it lands in the OR
When anesthesia coverage is short, the effects move straight through the perioperative department. Rooms close or open late. Cases get pushed, bumped to another day or sent elsewhere. Add-on cases wait. Patients who have already completed pre-op instructions, arranged rides and taken time off work get a phone call telling them to start over.
Perioperative nurses absorb much of that disruption. Pre-op nurses make the rebooking calls. Circulators reshuffle rooms and turnover plans. PACU teams deal with compressed arrival patterns when the day’s cases bunch into fewer rooms, and overtime climbs when late starts push cases past the scheduled end of the day.
The money behind the gap
The financial side explains why coverage has become so fragile, especially in surgery centers. Anesthesia groups say government rates have not kept pace with rising provider pay, and more surgery centers are paying subsidies, known as stipends, to keep anesthesia in the building.
For nurse leaders, the practical takeaway is that anesthesia coverage is now a negotiated, and sometimes precarious, arrangement. A contract dispute, a payer change or a single resignation can remove coverage from the schedule with little notice.
What rural teams already know
Facilities that have long worked with thin anesthesia coverage offer a preview of what other ORs may need to adopt. Common approaches include:
- Care-team models that match anesthesiologists, CRNAs and certified anesthesiologist assistants to cases by acuity and complexity. CAAs are authorized in 22 states, Washington, D.C., and Guam, so options vary by state.
- CRNA-led coverage where state scope-of-practice rules allow it.
- Tighter scheduling discipline, including block-time rules and case sequencing built around anesthesia availability rather than surgeon preference alone.
- Cross-trained perioperative staff who can flex between pre-op, OR and PACU when the day’s schedule changes.
What perioperative leaders can do now
The shortage is not something a nurse manager can fix, but it can be planned for. Periop leaders can track how often anesthesia gaps cause cancellations or closed rooms, so the cost is visible to administrators. They can build a rebooking and patient-communication playbook before the next gap, rather than during it. And they can ask to be at the table when their facility negotiates anesthesia contracts or care-team models, because the perioperative team lives with the result.
