For hospital CEOs and CFOs
Ask a hospital finance leader what an unfilled shift costs and you’ll usually get one of two answers. Either “nothing, we covered it,” or “whatever we paid to cover it at the last minute.”
Both answers are too small.
An unfilled shift isn’t a line item. That’s exactly the problem. The costs land in three different places, weeks or months apart, and nobody adds them up. So the shift looks free. It isn’t.
Here’s where the money actually goes.
Why this matters more than it used to
Margins are thin and getting thinner. Median hospital operating margin was negative 0.6% in January 2026 and negative 0.3% year to date through February, per Strata Decision data reported by HFMA. For rural hospitals it’s worse. Chartis found 41.2% of rural hospitals operating at a loss and 417 vulnerable to closure in its 2026 report, with 206 already closed or converted since 2010.
Coverage is also genuinely hard to buy. Physician vacancies now run $300,000 to $800,000 a month in lost gross billings depending on specialty, and recruitment alone averages over $150,000 per physician. Time to fill is up 23% since 2024.
So the shift you can’t fill isn’t a fluke. It’s the operating environment. That makes pricing it a real financial control, not an academic exercise.
The same three costs, different mechanisms
Where the gap sits changes how it hurts, which is why most hospitals never see the pattern.
An uncovered emergency department shift reroutes volume. Patients go elsewhere or walk out of the waiting room. An uncovered hospital medicine shift doesn’t reroute anything, because the patients are already in the building. It defers admissions and stretches the ones you have, so beds stay occupied by people who should have gone home.
Different mechanism, same three costs every time: care that doesn’t happen, patients who don’t come back, and staff who absorb the gap.
Cost #1: The care that doesn’t happen
In the ED, this is visible. The national median ER wait is 162 minutes, and about 2% of patients leave before they’re seen, per CMS data. Short a provider and that climbs. Benchmarking work published by BRG in 2025 puts a healthy left-without-being-seen rate at or below 2%, with real-world cohorts as high as 4.4%. And you don’t just lose the visit. About 13.1% of ED patients get admitted, so nine turned-away patients is nine visits plus roughly one admission plus everything that admission pulls through the building.
On the inpatient side it’s quieter and often larger. A thin hospitalist day means discharge decisions slip, and a bed you can’t turn over is a bed you can’t fill. Vizient priced an excess hospital day at $2,093 across 168 hospitals in 39 states in 2026. Four delayed discharges are more than $8,000 before you count the admissions you turned away for lack of a bed. Worth being precise here: Vizient’s own finding is that coordination, not staffing, is the biggest lever on length of stay. Their number tells you what a day costs. It doesn’t claim coverage gaps are why you have extra days. Use it to price the day, and judge for yourself how many of yours trace back to a thin schedule.
Either way, this is the cost most finance teams can already see. It’s also the smallest of the three.
Cost #2: Patients who don’t come back
This one doesn’t show up for years, and it’s the one that hurts.
A patient who drives past you once has now learned the drive. They’ve registered somewhere else. Their records are somewhere else. Their next imaging order goes somewhere else.
The data is blunt. A JAMA Network Open study published in January 2026 found 66.6% of rural patients with commercial insurance bypassed their nearest hospital. For nonemergent admissions, the kind hospital medicine depends on, the bypass rate was 77.4%. Those encounters sent $34.9 billion to receiving hospitals between 2012 and 2021, and the authors’ conclusion was direct: commercial bypass contributes to financial distress at rural hospitals.
Read that as a CFO and the point is uncomfortable. Three quarters of your best-paying elective volume is already willing to drive. A shift you couldn’t cover is a live demonstration that they should.
This isn’t rural-only either. Strata found hospital net revenue leakage grew from $38.6 billion to $48.4 billion between 2024 and 2025.
One turned-away patient is a rounding error. A pattern of them is a market share decision you didn’t get to vote on.
Cost #3: The staff who absorb the gap
Somebody works that shift. Even when no one is scheduled, somebody absorbs it: the nurse who picks up the load, the physician who stays four hours past sign-out, the director who covers it personally for the third time this quarter.
That absorption has a price, and it’s the largest of the three.
Burnout sits at 41.9% of physicians overall and 49.8% in emergency medicine, per the AMA’s 2025 Organizational Biopsy of nearly 19,000 physicians. On the nursing side the numbers are worse and easier to price:
- Each RN departure costs a hospital $60,090
- Every percentage point of turnover is worth roughly $295,000 a year to the average hospital
- The average hospital loses $5.19 million a year to nurse turnover
Those come from 2026 NSI retention data reported by Becker’s. Lose a physician instead and you’re looking at $150,000-plus in recruitment before you count the vacancy months.
Here’s the connection people miss. You don’t lose someone over one bad shift. You lose them over the twelfth one. The unfilled shift isn’t the cause of turnover, but it’s a reliable contributor, and turnover is the most expensive thing on this list by a wide margin.
Adding it up: two shifts, one rural hospital
Same 25-bed critical access hospital. Two different gaps.
An uncovered 12-hour ED shift, in a department seeing 30 visits a day
| 9 patients rerouted or walked, at $600 net revenue | $5,400 |
| 13.1% of those admitted, at $4,500 contribution margin | $5,306 |
| 1.8 patients who never return, over 5 years | $16,200 |
| Crisis-rate premium, 12 hours | $936 |
| Turnover, this shift’s share | $5,008 |
| Total | $32,849 |
Staffing it deliberately at the top of the 2026 locum emergency medicine range, $300 an hour, would have cost $3,600. The uncovered shift costs 9.1 times more.
An uncovered 12-hour hospitalist shift, in a service admitting 12 patients a day
| 3 admissions deferred or transferred, at $4,500 margin | $13,500 |
| 4 excess inpatient days at $2,093 | $8,372 |
| 0.75 patients who never return, over 5 years | $6,750 |
| Crisis-rate premium, 12 hours | $888 |
| Turnover, this shift’s share | $5,008 |
| Total | $34,518 |
Locum hospitalist coverage runs $140 to $200 an hour in 2026. Twelve hours at the top of that is $2,400. The uncovered shift costs 14.4 times more.
Note which one is bigger. The ED gap is the one everybody watches. The inpatient gap is quieter, cheaper to fill, and cost more.

What to actually do about it
Three things, in order.
Price your own gaps. Pull last year’s uncovered and last-minute-covered shifts across every service line, not just the ED. Multiply by your own version of the math above. Most finance teams find a six-figure number they’ve never seen on a report.
Stop buying coverage in emergencies. Emergency purchasing is the most expensive purchasing there is, and it produces the worst fit. 81% of healthcare organizations used locum tenens in 2024, two thirds of those placements to bridge gaps until a permanent hire. The organizations that do it well contract the coverage before the gap opens.
Build the schedule two months out, not two weeks. That’s the difference between a planned rate and a crisis rate, and between a physician who fits your culture and whoever is available Thursday.
One more reason not to wait: coverage is starting to be measured in public. CMS finalized the Emergency Care Access and Timeliness measure in the CY 2026 OPPS rule, so hospitals now publicly report how long admitted patients board in the ED. That measure is emergency-specific today. The direction of travel isn’t.
Where Inspire comes in
We place physicians and advanced practice providers, and we’ve been holding schedules for rural hospitals since 1996.
Our track record is in the emergency department: zero unstaffed shifts in nearly 30 years. We’re specific about that because it’s where we earned it, and because what made it possible isn’t emergency-specific at all. We build schedules two months in advance. We handle credentialing before it becomes an emergency rather than during one. We onboard every physician in person, so you’re not gambling on culture fit. That discipline is the product, and it travels across service lines.
We were founded by a physician who still takes shifts at partner hospitals. That’s why we say we won’t place someone somewhere we wouldn’t go ourselves.
If the number you just calculated made you uncomfortable, that’s the useful part. Schedule a meeting and we’ll walk through where your gaps actually are and what closing them would take.s across the region.
