CRNAs (certified registered nurse anesthetists) work across a surprisingly wide range of healthcare settings, from major trauma centers to small rural hospitals where they may be the only anesthesia provider on staff. Bureau of Labor Statistics data shows that roughly half of all nurse anesthetists work in physician offices and group practices, about a third work in general medical and surgical hospitals, and around 6% work in outpatient care centers. The remaining positions are spread across military facilities, VA hospitals, pain clinics, and other specialized environments.
Hospitals and Surgical Centers
Hospitals remain one of the most visible workplaces for CRNAs. Within a hospital system, the variety is enormous. A single health network might employ CRNAs at a level-one trauma center, a children’s hospital, an eye institute, a cancer center, and a community hospital, each requiring different anesthesia skills and case types. CRNAs in these settings handle everything from emergency surgeries and complex cardiac procedures to routine orthopedic cases.
Ambulatory surgical centers (often called outpatient surgery centers) are a growing employment sector. These freestanding facilities handle procedures that don’t require an overnight stay: colonoscopies, cataract removals, arthroscopic knee repairs, and similar same-day operations. The pace tends to be fast and predictable, with cases scheduled back to back during normal business hours. For CRNAs who prefer a more regular schedule without overnight call, these centers are a popular choice.
Physician Offices and Group Practices
The single largest employment category for CRNAs is physician offices, which accounts for over 51% of all positions nationally. This might sound surprising until you consider how the industry is structured. Many CRNAs are formally employed by anesthesia group practices, staffing companies, or physician-owned groups that then contract their services out to hospitals and surgical centers. So while a CRNA’s paycheck comes from a physician office or group, their day-to-day clinical work often takes place in an operating room across town. Others in this category provide sedation for procedures done directly in office-based settings, such as oral surgery practices, plastic surgery offices, or gastroenterology clinics.
Rural and Underserved Communities
CRNAs are the backbone of anesthesia care in rural America. According to the American Association of Nurse Anesthesiology, CRNAs represent more than 80% of anesthesia providers in rural settings. In many small-town hospitals, a CRNA is the only professional available to administer anesthesia for emergency surgeries, cesarean deliveries, or trauma stabilization. Without them, patients in these communities would face long transfers to distant facilities for even basic surgical needs.
This rural role is especially critical for obstetric care. CRNAs are often the only specialists providing access to obstetric anesthesia services in rural hospitals, meaning they’re the ones placing epidurals during labor and managing anesthesia for emergency C-sections. Research from NORC at the University of Chicago has highlighted how the availability of these providers directly affects whether rural hospitals can offer birthing services at all. When there’s no one to provide anesthesia, labor and delivery units close.
VA Hospitals and Military Facilities
The Department of Veterans Affairs employs CRNAs throughout its nationwide hospital system, where they work alongside anesthesiologists to deliver anesthesia tailored to each veteran’s individual needs. VA medical centers range from large urban campuses to smaller regional facilities, and CRNAs staff both. The U.S. military also employs CRNAs across all branches. Military nurse anesthetists provide care on bases, in field hospitals, and during deployments, often working with greater autonomy than their civilian counterparts due to the demanding and resource-limited environments they operate in.
Pain Management Clinics
Beyond the operating room, CRNAs also work in chronic pain management. In pain clinics, hospitals, and outpatient offices, they use a combination of interventional techniques (like nerve blocks and spinal injections), medications, and other therapeutic approaches to treat patients with ongoing pain conditions. This is a distinct career path from surgical anesthesia, and CRNAs who pursue it typically develop additional expertise in the physiological and psychological dimensions of chronic pain. It’s a growing niche, particularly as healthcare systems look for ways to expand access to pain specialists.
Independent Practice by State
Where a CRNA works is partly shaped by state law. Twenty-five states have opted out of the federal requirement that CRNAs practice under physician supervision. In these states, CRNAs can provide anesthesia independently, which opens up more opportunities for solo practice, direct contracting with surgical centers, and leadership roles in facilities that don’t have an anesthesiologist on staff. States that opted out early include Iowa, Nebraska, Idaho, Minnesota, and Kansas. More recent additions include Arizona (2020), Michigan (2022), and Massachusetts (2024). Some states, like Utah and Wyoming, have partial opt-outs limited to critical access hospitals and small rural facilities. In states that haven’t opted out, CRNAs still perform the same clinical work but do so under a supervisory or collaborative arrangement with a physician.
Work Schedules Across Settings
The work environment a CRNA chooses has a major impact on daily life. Hospital-based CRNAs commonly work 12-hour shifts. At Johns Hopkins, for example, a typical 12-hour track rotates between three-shift weeks (36 hours) and four-shift weeks (48 hours). Ten-hour, 14-hour, and 16-hour shifts also exist, though the longer options are typically voluntary. Some hospital positions require nights, weekends, holidays, and on-call time, but this varies dramatically by employer. Johns Hopkins’ main campus, for instance, doesn’t require any of those from its CRNAs.
Outpatient surgical centers and office-based practices generally offer the most predictable hours, often resembling a standard Monday-through-Friday schedule that follows the surgical caseload. Pain management clinics similarly tend toward regular business hours. On the other end of the spectrum, CRNAs at trauma centers or in military deployments may face unpredictable schedules with significant on-call demands. Many CRNAs deliberately choose their practice setting based on these lifestyle differences, and it’s common to shift between environments over the course of a career.
