The CFO's Staffing Dilemma
Hospital finance leaders are caught in a familiar bind. Permanent staff provide consistency and institutional knowledge, but they also represent fixed labor costs that don't flex with patient volume. When census drops, those salaries still hit the ledger. When it spikes, overtime premiums absorb the difference — often at 1.5× to 2× the base rate.
Locum tenens physicians and advanced practice providers offer a third path: variable-cost coverage that scales with clinical demand. But the business case for flexible staffing is rarely framed in financial terms that resonate in a boardroom. Let's change that.
Locum vs. Permanent: The Real Cost Comparison
The sticker shock of a locum bill rate — often $150–$300 per hour for physicians, depending on specialty — causes many finance leaders to dismiss locum staffing as a luxury. That reaction ignores the full cost picture.
A permanent physician hire carries costs that extend well beyond salary:
- Recruiting and onboarding: Agency fees (often 15–25% of first-year compensation), credentialing delays, and lost productivity during the 90-day onboarding window average $30,000–$80,000 per hire in healthcare.
- Benefits and overhead: Health insurance, malpractice coverage, CME allowances, retirement contributions, and administrative overhead add 25–35% to base compensation.
- Vacancy cost: The period between resignation and replacement — typically 90–180 days in competitive specialties — carries its own cost in overtime, agency fill, and diverted volume.
When you fully load the cost of a permanent hire and annualize it, the effective hourly rate frequently exceeds locum rates for the same specialty — with none of the flexibility. As we've covered in our analysis of the hidden costs of unfilled shifts, the downstream impact of a coverage gap — overtime cascades, LWBS spikes, diversion patterns — often dwarfs the cost of proactive flexible staffing.
Reducing the Overtime Burden
Overtime is a leading indicator of staffing stress, and it is expensive in ways that compound. Direct premium pay is the visible line item. The less visible costs are harder to eliminate:
Burnout-driven turnover. Physicians and nurses working extended hours leave at higher rates. Replacing a single experienced ED nurse costs $40,000–$60,000. Replacing a physician in a high-demand specialty can exceed $500,000 when recruiting, temporary coverage, and productivity ramp-up are included.
Quality metric degradation. Fatigued staff make more errors, driving readmissions and, in value-based contracts, penalty clawbacks.
Morale erosion. High overtime environments accelerate attrition of your best permanent staff, creating a self-reinforcing cycle: fewer staff → more overtime → faster burnout → more vacancies.
Deploying locum providers to absorb peak demand breaks this cycle. A targeted locum strategy — planned as a buffer, not a reaction — keeps permanent staff at sustainable hours while protecting quality metrics.
Budget Flexibility and Predictability
Flexible staffing is often framed as a cost driver. In practice, it is a cost control tool when deployed strategically.
The key shift is from reactive to proactive use. Most facilities turn to locum tenens after a vacancy has already opened — at which point they're paying short-notice premiums, competing with other facilities in a tight market, and absorbing operational disruption. Facilities that maintain ongoing locum relationships through a structured program can plan and budget coverage in advance, at standard rates, with predictable timelines.
This also creates genuine P&L flexibility. Unlike permanent headcount, locum engagements are variable expenses that can be scaled up during high-census periods and reduced during slower ones. For facilities operating on thin margins — which describes most community hospitals today — the ability to convert fixed labor cost to variable cost is a meaningful financial lever.
Rural and critical access hospitals, which often face chronic recruiting challenges in specific specialties, have been among the fastest adopters of this model. The strategic advantages are detailed in our coverage of why rural hospitals are turning to locum tenens.
How Rediworks Simplifies Billing and Invoicing
One of the operational friction points that deters finance teams from embracing locum staffing is the billing complexity: multiple providers, multiple agencies, varying rate structures, and manual invoice reconciliation that consumes hours of AP staff time.
Rediworks addresses this directly. Our platform centralizes all locum engagements under a single billing relationship, with:
- Consolidated invoicing: One invoice per billing cycle, regardless of how many providers or facilities are covered — no more reconciling dozens of agency invoices across specialties.
- Rate transparency: Every engagement is priced through our platform with full visibility into bill rates, travel expenses, and any applicable premiums before a provider is booked.
- Automated timekeeping: Digital time-and-attestation workflows eliminate paper timesheets and the disputes that come with them.
- Audit-ready records: Credentialing documentation, engagement contracts, and timekeeping records are stored in a single system — reducing the compliance burden when payers or accreditors request documentation.
For finance teams managing multiple agency relationships, this consolidation is often more valuable than the direct cost savings.
The Strategic View
The question isn't whether locum tenens is more or less expensive than permanent staff. The more useful question is: what is the right mix of fixed and variable labor for our volume profile, specialty mix, and market conditions?
For most facilities, the answer includes a meaningful flexible staffing component — planned, budgeted, and managed through a platform that gives finance and operations leaders the visibility they need to make data-driven decisions.
The hospitals that compete most effectively treat workforce flexibility as a strategic asset, not an emergency expense.
