Per Diem Nurse Staffing in Pennsylvania: A Facility Leader’s Guide

Pennsylvania’s post-acute and community-based providers are facing a staffing reality that’s not improving on its own. From SNFs in Reading and Harrisburg to personal care communities in Lancaster County, from behavioral health programs in Dauphin and Lebanon counties to IDD providers operating community homes across Central PA — the operators who’ve stabilized their schedules in 2026 have one thing in common: they’ve built per diem nurse staffing into their base plan, not their emergency plan.

If you’re a director of nursing, administrator, or HR leader at a Pennsylvania facility evaluating per diem nurse staffing, this is the working guide. We’ll cover what per diem staffing actually is, when it makes sense (and when it doesn’t), what to look for in a partner, and how to structure the relationship so it strengthens your retention instead of undermining it.

What per diem nurse staffing is

Per diem nurse staffing is a model where credentialed clinicians — RNs, LPNs, CNAs, and PCAs — pick up shifts at your facility on a shift-by-shift basis through a staffing agency. They’re employed by the agency, which handles credentialing, payroll, taxes, and benefits. You pay an hourly bill rate for the shifts you fill.

Done well, per diem coverage gives your core team predictable time off, reduces overtime spend, and keeps your unit ratios in compliance without forcing your full-time staff into burnout-driving rotations.

When per diem makes sense for PA facilities

Per diem staffing is most valuable when you use it as planned capacity, not emergency rescue. The PA facilities getting the most value out of agency partnerships use it in these specific ways:

• Weekend and overnight coverage. Predictable per diem rotations on the shifts that strain your core team most.
• FMLA, maternity, and extended leave bridging. Multi-week LPN or RN coverage that doesn’t require you to hire a permanent replacement you’ll have to let go later.
• Census flex. Adding hours when your census climbs and pulling back when it drops, without hiring/laying off.
• Specialty backfill. Hard-to-fill roles like MDS coordinators, RN supervisors, behavioral health LPNs, or IDD clinical nurses that take months to recruit permanently.
• New-program ramp-up. A new memory care unit, behavioral health expansion, or IDD service line where you don’t yet know steady-state staffing needs.

Where per diem fits across the PA care continuum

Skilled nursing and rehab

SNF and sub-acute rehab settings are the largest single use case for per diem staffing in PA. RN supervisors on nights and weekends, LPN charge nurses across all shifts, and CNAs for floor coverage and assist-of-two needs are the most common requests.

Personal care, assisted living, and CCRCs

Personal care and assisted living communities — including the major CCRCs across Lancaster, Lebanon, Cumberland, and Dauphin counties — rely heavily on per diem LPN and CNA support for medication passes, resident assessments, and overnight wellness coverage. Memory care units particularly benefit from a small bench of consistent per diem staff who know the residents.

Behavioral health

Inpatient psych, residential treatment, geriatric behavioral programs, and crisis stabilization units across PA have some of the most acute LPN and RN staffing gaps. Per diem coverage works best when your staffing partner pre-screens for behavioral health experience — a generalist LPN dropped into a high-acuity psych unit creates more problems than it solves.

IDD providers

IDD providers operating community homes, day programs, and ICF/IID facilities need LPN and RN per diem support for medication administration, ICF/IID clinical compliance, and treatment plan oversight. PA IDD staffing is one of the most under-served per diem markets, and the right agency partnership can make a real operational difference.

Hospice and

End-of-life care, palliative visits, and short-stay benefit from per diem RNs who can cover weekends, holidays, and on-call rotations without burning out your core team.

How to pick the right partner

The single biggest predictor of whether per diem staffing helps or hurts your facility is the partner you pick. Our full guide on choosing a PA staffing agency goes deeper, but here are the essential questions:

• How many PA-based clinicians are in your active per diem pool, and how many regularly cover my vertical?
• What’s your typical time-to-fill for a same-week request?
• Who is my actual point of contact — named recruiter, or portal?
• How transparent is your credentialing process? Can I see what’s on file for each clinician you send?
• What’s your bill rate structure, and are there hidden premium or holiday tiers?
• Do you handle per diem, local contract, and travel under one roof?

What to expect operationally

• Faster fills for predictable needs. Per diem partners can fill a 7am Saturday shift in hours if you give them notice. Same-shift emergency fills are possible but premium.
• Better fills when the partner knows your unit. Concentrate volume with one or two PA-based agencies so they learn your residents, protocols, and culture.
• Consistent invoices and credentialing. A good partner makes admin disappear; a bad one creates more work than it removes.
• A real conversation when things go sideways. Cancellations, no-shows, and difficult shifts happen. The question is whether your partner picks up the phone.
