For many hospital leaders, physician coverage has become a daily fire drill. A shift opens, a service line is short, or patient demand rises faster than expected. The fastest answer is often to call an external locums agency. That can keep care moving in the moment, but it can also create high costs, less control, and a staffing plan that feels reactive. Over time, the same gaps come back, the same agencies are called, and the spend keeps growing.

There’s a better way to approach the problem. An internal float pool helps your health system use trusted physicians and advanced practice providers to cover open needs before you turn to outside agencies. Instead of treating every gap as a one-off emergency, you build a dependable group of clinicians who know your organization and can work where they are needed most. The goal is not to eliminate locums completely. The goal is to use external help when it is truly needed, not as the default answer to every opening.

Key takeaways

• An internal provider float pool gives your own credentialed providers the first look at open shifts before an outside agency is called.
• Shifting coverage from agencies to an internal pool can reduce cost per shift by roughly 20% to 30%.
• A float pool gives leaders visibility into open shifts, hard-to-cover specialties, and recurring gaps that a locums invoice never shows.
• A pool that scales needs recruiting, credentialing, scheduling, pay support, reporting, and an owner. A spreadsheet and a scheduling tool will not get you there.

What Is an Internal Provider Float Pool?

At its core, an internal float pool is a group of credentialed providers who can work across the enterprise. Some may want flexible work rather than a full-time job. Some may be strong candidates who are not the right fit for one permanent opening but would be a great fit for your system. Others may be former locums clinicians who would rather have a direct relationship with the health system. What they have in common is that they can help you fill gaps with providers who are already connected to your organization.

Why an Internal Float Pool Beats Default Locums Coverage

Providers who already know your system

That connection matters. A provider who understands your clinical standards, local workflows, electronic systems, and culture can often step in with less friction. Department leaders do not have to start from scratch every time a need comes up. The provider knows the system, and the system knows the provider. That can make coverage smoother for patients, care teams, and the provider themselves. It also helps build a more consistent experience across sites and service lines.

The financial case: 20% to 30% lower cost per shift

The financial case is just as important. Locums agencies serve a real purpose, but agency coverage comes at a premium. When more shifts are filled through your own pool, you reduce agency markups and gain more control over rates and spending. Programs that shift coverage from outside agencies to an internal pool can reduce the cost per shift by roughly 20% to 30%. In a large health system with regular openings across multiple sites, that difference can add up quickly.

Visibility that a locums invoice never gives you

An internal float pool also gives leaders something that is often missing in a traditional locums model: visibility. You can see who is available, which shifts are open, what specialties are most difficult to cover, and where needs keep coming back. That information helps you make better decisions. A recurring need may point to a recruiting issue, a scheduling problem, a service line that needs more support, or a permanent role that should be created. Without clear data, leaders are left looking at invoices after the fact instead of planning ahead.

A better experience for your providers

There is a provider benefit, too. Many clinicians want more choice in how they work. They may be interested in extra shifts, part-time work, or a flexible role that lets them stay connected to clinical care without making a full-time commitment. A well-run float pool can give them that option. When providers can easily view shifts, enter availability, manage time, and communicate through one simple process, the pool becomes a valuable part of the provider experience, not just a staffing fix.

Why Building a Float Pool on Your Own Is Harder Than It Looks

The hard truth is that launching a float pool on your own is much harder than it first appears. It is easy to think the answer is a shared spreadsheet, a scheduling portal, or one person coordinating coverage by email. That may work for a small pilot. It will not work when you are managing many clinicians, locations, specialties, and changing needs. At that point, every manual step creates delays, missed details, and more work for people who already have full-time jobs.

What a float pool needs in order to scale

A pool that can scale needs more than a list of available providers. It needs:

• Steady recruiting
• Structured onboarding
• Credentialing and compliance checks
• Scheduling rules
• Timekeeping and pay support
• Communication and approvals
• Reporting

It needs a clear process that gives internal providers the first look at a shift before an outside agency is called. It also needs someone who owns the program, watches the data, solves issues quickly, and helps leaders improve the model as it grows. Without that operating structure, a good idea can become another manual program that creates more stress than relief.

Technology is part of the answer, not the whole answer

Technology is part of the answer, but technology by itself is not enough. A scheduling tool cannot build a provider pipeline, keep credentials current, explain a workflow to a physician, or help finance and operations decide where the next staffing dollar should go. A real workforce strategy brings all those pieces together. It gives recruiters, clinical leaders, finance teams, and executives a shared view of the workforce so they can act from the same information instead of working in separate lanes.

The Built-In Conflict in the Locums Market

This is also where the usual staffing market has a built-in conflict. The five largest locums companies account for a major share of locums spend, and their business grows when agencies fill more shifts. A 30% reduction in external locums use may be a major win for a hospital, but it can cut into the revenue those firms are built to earn. That does not mean they cannot offer useful technology or support. It does mean a health system should look closely at whether its partner is truly motivated to reduce agency use or simply make agency use easier to manage.

How Syncx Runs a Physician Float Pool Differently

Syncx is the only true option for a health system that wants a partner whose success grows when its locums use goes down. Syncx combines a connected platform with the real work of running a float pool, including provider onboarding, credentialing, scheduling, payroll support, reporting, float-pool health reviews, and dedicated program management. It does not have locums revenue to protect, so the incentives are clear. This is why we recently helped a major health system slash their locums usage by 30%, saving $51 million over the last 4 years.*

When your internal pool fills more shifts, controls more spend, and gives leaders better visibility, Syncx wins because your health system wins. That is the difference between simply adding a scheduling tool and building a scalable staffing strategy that keeps care moving while bringing more control back inside your system.

Frequently Asked Questions

What is a physician float pool?

A physician float pool is a group of credentialed physicians who can work across a health system’s sites and service lines to cover open shifts. The providers are already connected to the organization, so they can step in with less friction than an outside agency clinician.

Does an internal float pool replace locums agencies?

No. The goal is not to eliminate locums completely. An internal float pool gives your own providers the first look at open shifts, so external help is used when it is truly needed rather than as the default answer to every opening.

How much can an internal float pool save compared to locums?

Programs that shift coverage from outside agencies to an internal pool can reduce the cost per shift by roughly 20% to 30%. In a large health system with regular openings across multiple sites, that difference adds up quickly.

Who joins a physician float pool?

Providers who want flexible work instead of a full-time job, strong candidates who were not the right fit for one permanent opening but fit the system, and former locums clinicians who would rather have a direct relationship with the health system.

Can a hospital run a float pool with a spreadsheet or scheduling tool?

That may work for a small pilot. At scale, a float pool needs recruiting, onboarding, credentialing, compliance checks, scheduling rules, timekeeping, pay support, communication, approvals, reporting, and someone who owns the program. A scheduling tool alone cannot do those things.
