For a health system executive, physician workforce planning stopped being a purely operational concern some time ago. Every open physician role now carries a dollar figure attached to it, and every staffing decision carries clinical risk attached to it too. That combination has pulled workforce planning out of HR and placed it next to finance and operations on the strategic agenda.
This shift is being driven by fundamental disruption in the underlying math of physician recruitment. A structural physician shortage, a credentialing and licensing system built for careful decisions rather than fast ones, and a workforce that increasingly prioritizes flexibility over a single employer have forced sophisticated health system leaders to treat workforce composition as a strategic asset rather than a staffing line item. Four trends are driving that change.
Workforce Planning Is Becoming Portfolio Management
The old talent acquisition model assumed a stable baseline: recruit permanent staff and tap temporary coverage only when something unexpected happened. That assumption no longer holds. AAMC physician workforce projections point to a shortfall of up to 86,000 physicians by 2036, and the constraint is structural. Residency funding caps limit how fast new physicians can be trained, regardless of how much a health system is willing to spend on recruiting.
That dramatically changes the talent questions a CFO or CMO needs to answer. It is no longer “how do we fill this role permanently?” It is “what mix of employed staff, targeted contingent coverage, and flexible capacity gives us the most resilient service line at the lowest total cost?” Locum tenens fits into that mix as a deliberate lever, not a fallback. Used this way, it unlocks options not available under the old model. Systems can test a new service line without overcommitting to headcount, protect against retirements and leave-driven gaps before they become emergencies, or cover hard-to-fill specialties without absorbing the retention risks of stretching an already strained permanent team.
Organizations still treating locums as a last resort are also the ones absorbing the highest downstream costs. Independent analyses of physician turnover put the lost annual revenue from a single vacant primary care physician at nearly $1 million, and in service lines like rural obstetrics, staffing gaps have threatened to close entire units. Given these risks, disciplined workforce portfolio management has become a C-suite imperative built on the same return logic a health system already applies to its capital budget.
“Workforce planning used to mean keeping every seat filled with a full-time employee. Now it means building a deliberate mix of employed staff and flexible coverage, sized to the actual risk in each specialty and each market. The systems getting this right are not the ones with the biggest recruiting budget. They are the ones treating their workforce like a portfolio.” - Bales Nelson, CEO, Fusion Health
Fill Rate Is Being Replaced by Quality of Hire and Total Cost
Fill rate and time-to-fill were useful measures when the talent acquisition goal was simply to get a qualified provider into every open seat. These metrics say nothing about whether the provider stayed long-term, whether the provider fit the team, or whether the hire produced the results that were modeled in business cases. A 100 percent fill rate built on providers who underperform is not a success. It is an expensive cycle that regularly resets the search and adds additional strain to the permanent team.
Sophisticated health system leaders are pulling this metric apart and asking sharper questions, the same questions that define quality of hire in any people-driven business. Did the placement reduce strain on the existing team, or add to it? Did the coverage protect billable capacity, or did credentialing and payer enrollment delays leave the provider unable to see patients for weeks after arrival? Did the clinician ramp, produce, and retain as expected? Those questions carry real financial weight in an industry where days lost translate directly to thousands of dollars.
This is the same discipline health systems already apply to clinical outcomes: measure what happens downstream, not just whether the intervention occurred. Recruitment is catching up.
“Fill rate tells you a seat was filled. What we get asked now is how many of our providers are still there six months later, what was their impact, and whether the facility would want to work with us again. Those are the things that tell you if a placement worked.” - Bales Nelson, CEO, Fusion Health
Speed to Start Is an Infrastructure Problem, Not a Sourcing Problem
When an open shift carries a real financial and clinical cost, every day of delay matters. The instinct is to blame sourcing, as in not enough providers in the pipeline. In practice, many delays sit after a clinician has been confirmed: credentialing, internal approvals, payer enrollment, and scheduling and travel coordination. Those steps exist for good reasons and are not the problem. The problem is that most health systems manage them through disconnected systems and separate vendor relationships, one for locums, one for travel staff, one for permanent recruiting, with no shared visibility into where a candidate actually sits in the pipeline or what it is truly costing to get them there.
The clients we work with who are moving fastest are not cutting corners on credentialing. They are redesigning around it: parallel workflows instead of sequential ones, proactive licensing support that starts before a confirmed need exists, and a single view of workforce data that shows leadership where time and money are actually being lost across every labor channel at once. That last piece matters more than it sounds. Without centralized visibility, it is difficult to know whether a slow fill is a sourcing problem, a credentialing bottleneck, or a partner performance issue, and health systems end up solving the wrong problem.
Auditing the full workflow from need identification to a provider’s first billable day, across every staffing channel a system uses, reveals where time is really being lost. It is rarely where leadership assumes.
“We can source quickly. The real question is whether the rest of the process, credentialing, enrollment, scheduling, is built to move with the same urgency. We’ve made credentialing a focus area for just this reason. Speed at the front end doesn’t have an impact if the middle or end of the process is slow.” - Bales Nelson, CEO, Fusion Health
The Staffing Partner Relationship Is Becoming a Market Intelligence Function
Staffing has operated for years on a transactional model: a system has a need, a firm fills it, a fee is paid. That model is not going away. For high-volume, lower-complexity contingent labor, it is increasingly being run through vendor management systems and managed service programs that standardize supplier relationships for efficiency. That consolidation is a real and growing trend, and it is the right tool for commodity staffing needs.
Physician and advanced practice workforce strategy is different. Decisions about which service lines to protect, which markets are tightening, and what is actually moving providers toward or away from an assignment this year are not decisions a standardized panel can inform. Sophisticated health system leaders are asking their physician staffing partners for exactly that kind of insight: a seat in multi-year service line planning conversations, not just a fast response to a requisition.
That kind of insight does not come from a benchmarking report or a database query. It comes from a partner that is placing physicians and APPs and having these conversations every day. Firms that operate effectively across specialties and markets, and that pair that perspective with real operational discipline in credentialing and a focus on client and candidate experience, are increasingly in demand. That combination is what separates a strategic workforce partner from a panel vendor, and it is increasingly the basis on which sophisticated executives decide who earns a seat at the planning table.
“The calls we get now are not just ‘I need a hospitalist.’ They are ‘here is what we are trying to do with this service line over the next two years, what are you seeing in the market?’ That is not a conversation you have with a vendor. It is a conversation you have with a partner.” - Bales Nelson, CEO, Fusion Health
Looking Ahead
These four shifts point to the same conclusion. Workforce composition, who provides care, how they are engaged, and how quickly a system can adjust that mix, has moved from an HR concern to a strategic one. The health systems pulling ahead are not necessarily the ones with the largest recruiting budgets. They are the ones managing their workforce the way they manage any other strategic asset: with a portfolio view, outcome-based metrics, redesigned infrastructure, and a partner who brings more than capacity to the table.

Frequently Asked Questions
Why are health system executives treating locum tenens as a workforce planning tool instead of emergency coverage?
An AAMC-projected structural physician shortage, reaching up to 86,000 physicians by 2036, means health systems cannot rely on permanent hiring alone to close every gap. Locum tenens is increasingly built into workforce plans as a deliberate lever, used to protect service lines, test new capacity, and manage retirements before they become emergencies, rather than called in only after a vacancy has already caused disruption.
How should health system leaders measure the return on a staffing partnership?
Fill rate and time-to-fill still matter, but they do not capture whether a placement held, whether it protected billable capacity, or whether it reduced strain on the permanent team. Leading organizations now track downstream measures such as retention of the placement, credentialing and enrollment speed, and whether coverage decisions supported service line continuity.
What actually causes delays in getting a provider to their first day?
Delays are rarely a sourcing problem. They typically come from disconnected processes across credentialing, payer enrollment, internal approvals, and scheduling, often managed through separate systems for each staffing channel. Health systems that redesign these workflows to run in parallel, and gain unified visibility across every labor channel, cut time to start without compromising credentialing quality.
What should health system executives expect from a staffing partner today?
For high-volume, standardized contingent labor, vendor management systems and managed service programs are increasingly the right tool. For physician and APP workforce strategy, sophisticated executives expect more: real-time market intelligence, operational discipline in credentialing and enrollment, and a partner who can participate in multi-year service line planning rather than simply responding to individual requisitions.
How does workforce portfolio management reduce financial risk for a health system?
By sizing the mix of employed staff and flexible coverage to the actual risk in each specialty and market, rather than defaulting to permanent hiring everywhere or locums only in emergencies, health systems can protect revenue-generating service lines, avoid the retention cost of overstretching permanent staff, and avoid the higher long-term cost of reactive, last-resort staffing decisions.
