CRNA schedules range from strict daytime hours with zero call to 24-hour in-house shifts covering everything that comes through the door. The schedule often matters more to daily life than the salary does, so understand the model before you sign anything.
Here are the common structures and how call pay typically works.
Key points
- Shifts run from 8-hour ASC days to 24-hour in-house hospital call.
- Heavy home call can be worse than in-house call.
- Call pay mixes stipends, callback rates, and shift differentials.
- Ask how call changes when someone quits; paper schedules lie.
Common shift models
- 8-hour shifts (five days a week). Common in ASCs, offices, and some hospital groups. Predictable, but you are there every weekday, and "out when the room finishes" can stretch past eight hours unless relief is guaranteed.
- 10-hour shifts (four days a week). A popular hospital pattern. One weekday off helps with burnout and errands.
- 12- and 13-hour shifts (three days a week). Fewer days on site, longer days. Common where hospitals run late rooms.
- 16-hour shifts. Often an evening or late-stay role layered on top of the day team, or part of a weekend program.
- 24-hour shifts. Usually in-house call at hospitals with OB or trauma. Some rural jobs run 24s with post-call days off. A week of 24s followed by a week off exists in some rural and locum arrangements.
- 7-on-7-off and block schedules. More common in locum and rural roles. See /locum-crna/.
ASC and office jobs cluster at the predictable end. Hospital jobs, especially with OB, trauma, transplant, or cardiac coverage, carry the call burden. See /crna-day-in-the-life/ for how those settings differ.
Call models
- In-house call. You are physically at the hospital, doing cases or available for them, typically 16 or 24 hours. You work whatever comes in: emergent sections, epidurals, traumas, add-ons.
- Home call (beeper call). You are at home within a required response time, often 30 minutes. You come in when called. Light home call can mean uninterrupted sleep most nights. Heavy home call at a busy OB hospital can be worse than in-house call because you drive in repeatedly.
- Backup or second call. Covers when first call is already in a case. Usually lighter, usually paid less.
- No call. Many ASC, office, GI, and some hospital daytime roles have none. These often trade some pay for lifestyle.
How call pay usually works
Structures vary a lot by employer, and exact rates are set by local markets, so treat these as patterns to ask about rather than fixed numbers:
- Call stipend. A flat amount per call shift (per night or per weekend) just for being available.
- Callback pay. An hourly rate, often at a premium such as time-and-a-half, for hours actually worked when called in, sometimes with a guaranteed minimum (for example two hours per callback).
- Shift differentials. Extra hourly pay for evenings, nights, and weekends on scheduled shifts.
- Beeper plus activation. Home call pays a lower hourly or flat beeper rate, then converts to a higher rate when you are activated.
- Salaried with call built in. Some positions bundle expected call into base salary. If so, ask exactly how many call shifts per month that salary assumes, and what happens above that number.
- Post-call time off. Whether you get the next day off after a 24 or a busy night, and whether it is paid.
For 1099 and locum work, call coverage is usually priced explicitly in the contract: a daily or hourly rate plus callback terms. Run any offer through /crna-1099-vs-w2-calculator/ and see /1099-crna/ for the tradeoffs.
Questions to ask about call in an interview
Call burden is where jobs hide their true cost. Ask precisely:
- How many call shifts per month, and is call in-house or from home?
- What is the average number of callbacks per call night, and how late do add-ons typically run?
- Who else is on call with me: backup CRNA, anesthesiologist, second call team?
- How is call paid: stipend, callback rate, minimums, differentials?
- Is there post-call relief, and is the post-call day guaranteed off?
- How is the call schedule built, and how far in advance? Can I trade shifts?
- Does call include OB coverage, and is OB its own call pool?
- What happens when someone quits: does everyone's call go up until the position is filled?
That last question matters most. In a short-staffed group, the schedule on paper is fiction. Ask how many open positions exist right now and how long the last opening took to fill. More interview guidance at /crna-job-interview-questions/, and negotiation tactics at /crna-contract-negotiation/.
Is call pay included in published CRNA salaries?
Surveys and BLS wage data report total wages, so heavy-call jobs partly explain the top of the pay range. BLS reports a mean of $248,320 for nurse anesthetists in May 2025. See /crna-salary/ for the full picture and /crna-take-home-pay/ to model a specific offer.
Do new grads take more call?
Often yes, since call assignments frequently follow seniority. Weigh that against the learning value: call cases build airway and crisis skills quickly. See /new-grad-crna-first-job/.
Can I work as a CRNA with no call at all?
Yes. ASC, office-based, GI, and some outpatient hospital roles have no call. Expect tradeoffs in pay, case variety, or both. Browse current openings at /best-crna-jobs/.
