Cases per day 8
Cases this CRNA's room runs on a normal day. Multiplies the margin lost for every day the room sits dark.
Net revenue per case $3,500
Average amount collected per case after payer mix and contractual adjustments. The starting point for what each cancelled case costs you.
Cases rescheduled 25%
Share of cancelled cases you'll recover on a later date. These are subtracted from the loss.
Contribution margin 70%
Share of each case's revenue left after supplies, implants and other variable costs. Only this portion counts as lost.
Days unstaffed 45
OR days the position will sit open before a permanent CRNA starts. Sets the length of the vacancy.
Days until locum starts 10
Days for credentialing and onboarding. Subtracted from the vacancy, because those days are lost with or without a locum.
Locum bill rate / hr $290
Hourly rate the agency bills you, fee included. Multiplied by billed hours to get the daily labor cost.
Billed hours / day 10
Hours billed per day, including any guaranteed minimum in the contract. Multiplied by the bill rate.
Travel & housing / day $350
Daily travel, lodging and per diem paid on top of the bill rate. Added to each covered day's locum cost.
Budgeted CRNA comp / yr $240,000
Annual salary plus benefits budgeted for the open position, divided by 260 working days. Used only for the budget view.

How the math works

Days covered = days unstaffed minus days until the locum starts. Margin lost during credentialing happens whether or not you hire a locum, so it is left out of the comparison.

Margin lost if dark = cases per day × net revenue per case × contribution margin × (1 − share rescheduled) × days covered. Using margin instead of revenue accounts for the supplies and variable costs you don't spend when a case is cancelled.

Locum cost = (bill rate × billed hours + travel and housing) × days covered.

Budget view compares locum spend with the budgeted comp for the open position over the same days, at 260 working days a year. That salary goes unpaid whether or not you hire a locum, so it shows the effect on your budget and does not change the recommendation.

Not included: overtime or call pay for existing staff, surgeon or referral loss to competing facilities, and recruiting fees for the permanent hire. Each of these usually makes a dark OR more expensive.
