Quick Answer: Credentialing time-to-first-shift is the interval between a physician's application submission and their first authorized clinical shift. The national average is 90–180 days. Best-in-class is under 10 business days. SANNEXUS median: 7 business days.
The Metric That Changes Everything
Credentialing time-to-first-shift is the number of calendar days between a physician accepting a position offer and the date they work their first clinical shift at that facility. For the complete context on why this metric matters, see our complete guide to physician credentialing.
It is the most important metric in physician staffing. It is also almost never measured.
Traditional hospital staffing metrics track vacancy rates, fill rates, premium labor spend, and agency cost-per-hire. These are all lagging indicators. Time-to-first-shift is the leading indicator that determines whether all the others improve.
A hospital with a 90-day time-to-first-shift is not solving its staffing problem. It is managing it 90 days later than it should.
The National Benchmark
Physician credentialing through traditional hospital Medical Staff Office processes takes an average of 90 to 180 days in the United States. This range reflects:
- Primary source verification: 20-40 days
- Credentials committee scheduling and review: 30-60 days
- Medical Executive Committee approval: 15-30 days
- Background checks, references, and supplemental documentation: 15-30 days
- Administrative processing: 10-20 days
These steps run largely sequentially. A delay at any point — a missing document, a delayed reference, a monthly committee meeting just passed — restarts the clock on that stage.
| Specialty | Traditional Credentialing Time | SANNEXUS Time-to-First-Shift |
|---|---|---|
| Emergency Medicine | 90–120 days | 10–14 days |
| Radiology | 100–150 days | 12–18 days |
| Hospital Medicine | 75–100 days | 7–10 days |
| Surgery (general) | 120–180 days | 14–21 days |
What 90 Days of Waiting Actually Costs
The financial impact of a 90-day time-to-first-shift is rarely calculated explicitly in hospital operations. When it is, the numbers are significant.
For the Hospital
Immediate premium labor cost: A hospital that needs an emergency medicine physician on day 1 and cannot credential one for 90 days must either run the department understaffed — increasing patient safety risk — or pay a premium to an agency for short-notice coverage. Agency premium rates for emergency EM coverage run 35-60% above market. On a 12-hour EM shift at $350/hr market rate, a 45% premium means $158/hr in additional cost. Over 90 days of daily gap coverage, that is approximately $427,000 in excess premium labor for one position.
Lost procedure revenue: An uncredentialed interventional radiologist cannot generate procedure revenue. An interventional radiology fellowship-trained physician performing 8-10 procedures per day at average reimbursement generates $8,000-$14,000 in daily hospital revenue. At 90 days of credentialing wait, that is $720,000 to $1.26 million in unrealized revenue.
Recruiting failure risk: Physicians who accept a position and then experience a 4-to-6-month credentialing delay before their first shift sometimes withdraw their acceptance and accept an offer elsewhere. The cost of a failed physician hire — re-advertising, recruiter fees, candidate time — typically runs $30,000 to $75,000 for a hospitalist, and $75,000 to $150,000 for a specialist.
For the Physician
A physician who accepts a locum position and then waits 90 days for credentialing to complete is losing income during that window.
At a blended emergency medicine rate of $320/hr and 4 shifts/week at 12 hours/shift:
- Weekly income at capacity: $15,360
- 90-day wait = 13 weeks lost
- Income lost during credentialing: $199,680
This is the reason physicians who have experienced one long credentialing wait often approach locum work differently afterward — they are reluctant to commit to a position until credentialing is confirmed, which further delays start dates and compounds the problem.
Why the Traditional Credentialing Process Is Slow
The 90-to-180-day time-to-first-shift is not primarily a bureaucratic failure. It is a structural problem baked into how hospital credentialing was designed. Our full breakdown of why credentialing takes so long covers each structural cause in detail.
Reason 1: No portability standard. Each hospital operates its own credentialing process, to its own bylaws, on its own timeline. There is no national portability standard for physician credentials. A physician who is fully credentialed at 8 hospitals must still go through the complete process from scratch at hospital 9.
Reason 2: Sequential committee scheduling. Credentials committees and Medical Executive Committees at most hospitals meet monthly. If an application is complete and ready for committee review on day 31, it waits until day 60 for review. This scheduling lag alone adds 15-30 days to almost every credentialing cycle.
Reason 3: Primary source verification queues. State medical boards, NPDB, and ECFMG respond to verification requests on their own schedules. During high-volume periods, NPDB queries can take 5-10 business days; some state boards take 2-4 weeks.
Reason 4: Document gap discovery. Hospitals often discover missing or expired documents mid-process — after the application has been submitted and initial review completed. Each discovery adds days to weeks of back-and-forth.
Reason 5: No physician-side transparency. In most credentialing processes, the physician has no visibility into where their application is in the queue, which documents have been verified, and what is holding up the process. Without visibility, physicians cannot intervene to accelerate resolution.
What 10 Days Looks Like: The SANNEXUS Model
SANNEXUS achieves a 10-to-18-day time-to-first-shift across emergency medicine, radiology, and hospital medicine by attacking each of the five structural problems simultaneously. The physician credentialing passport is the core mechanism that makes this possible.
Portable primary source verification. SANNEXUS Central performs PSV once per physician and makes the verified record available to every hospital in the network. Hospitals do not repeat verification — they review, confirm, and advance.
Bylaw gap analysis before application. Before a physician applies to a position, SANNEXUS Central has already run their credential set against that hospital's bylaws and identified every gap. No mid-process surprises.
Pre-packaged credential files. When a physician accepts a position, the hospital's MSO receives a complete, pre-formatted credential file — everything they need for committee presentation, pre-verified and organized to their bylaws. Committee preparation time drops from weeks to days.
Real-time status tracking. The physician and hospital both have real-time visibility into where the credentialing process stands. Both parties can proactively resolve issues as they arise.
IMLC integration. SANNEXUS integrates IMLC license status into the passport, enabling multi-state credential reach from a single passport build.
Implications for Hospital Operations Leadership
Time-to-first-shift should be a KPI on every VP of Operations and VP of Medical Affairs dashboard at any hospital that uses locum or supplemental physician coverage. For a full analysis of hospital credentialing software options and what health systems get wrong in evaluating credentialing technology, see our dedicated guide.
Current state benchmark: Measure your actual time-to-first-shift for the last 12 locum hires. Calculate the premium labor cost attributable to coverage gaps during those credentialing windows. This is your baseline.
Target state: A hospital using SANNEXUS as its primary locum and supplemental physician channel targets a 10-18-day time-to-first-shift. The premium labor cost reduction is immediate and measurable.

The Language Shift
Traditional locum tenens agencies have never made time-to-first-shift a primary marketing metric because it is not in their interest. An agency earns its margin on the daily spread between what a hospital pays and what a physician receives. A faster credentialing process means less time billing the hospital for that gap coverage. For a detailed comparison, see SANNEXUS vs. traditional agencies.
SANNEXUS has the opposite incentive structure. We are a marketplace — we earn when physicians work. The faster a physician is working, the better for everyone. Time-to-first-shift is the metric that most directly reflects whether we are doing our job.
This is why we coined it. And why we publish it.
FAQ
Q: What is the average physician credentialing time in the US?
The national average is 90 to 180 days depending on specialty, facility type, and geography. Emergency medicine typically credentials in 90-120 days; surgical specialties can take 120-180 days.
Q: What is the fastest possible credentialing time at a hospital?
Even expedited credentialing under emergency or provisional privilege processes typically takes 14-30 days at most US hospitals. SANNEXUS achieves 7-18 days through pre-verification and bylaw pre-analysis — this is near the structural minimum given committee scheduling requirements.
Q: What is provisional credentialing and why doesn't everyone use it?
Many hospitals offer temporary or provisional privileges that allow a physician to work before full credentialing is complete, typically for 90-120 days under department chair supervision. However, provisional privilege policies vary widely by facility and are typically reserved for urgent staffing situations or new permanent hires. Locum physicians are often ineligible. SANNEXUS achieves full privileges in the same or shorter time as most provisional pathways.
Q: How does SANNEXUS achieve 10-18 days when hospitals say credentialing cannot go faster?
The 90-180-day timeline is a function of the process, not the calendar. PSV that takes 30 days in isolation takes 3-5 days when queried in parallel by a dedicated platform. Committee preparation that takes weeks takes days when the file arrives pre-organized to the hospital's own bylaws. The bottleneck is never a single step — it is the sequential accumulation of delays that SANNEXUS addresses in parallel.
The Bottom Line
Time-to-first-shift is the metric that reveals whether a physician staffing model is working. The national average of 90 to 180 days represents a structural failure — not a regulatory necessity.
SANNEXUS was built to solve this metric. The credentialing passport model reduces time-to-first-shift to 10-18 days across emergency medicine, radiology, and hospital medicine.
