Allied Health Staffing Shortages: What Hospitals Need to Know

Allied Health Staffing Shortages: What Hospitals Need to Know

Ask a hospital administrator about their toughest staffing problem and nursing comes up first. Nursing vacancies get tracked on every staffing dashboard and budgeted for every quarter. Allied health roles, radiology and imaging techs, respiratory therapists, surgical techs, and lab techs, rarely get the same visibility until a CT scanner sits idle or a ventilator patient waits on a respiratory therapist who is not on shift.

National vacancy rates for imaging technologists and respiratory therapists commonly run between 10% and 18%, on par with or higher than RN vacancy rates in many markets. The difference is the candidate pool behind each opening. Allied health credentials are narrower and the schools producing graduates are fewer, so a tech certified in one specialty usually cannot cover an opening in another.

Why Allied Health Shortages Get Overlooked

Allied health shortages get overlooked because nursing dominates the staffing conversation, not because the gap is smaller. Nursing is the largest single job category in most hospitals, so nursing vacancies show up first in every staffing report and every budget meeting.

Allied health departments are smaller, so a handful of open positions can look minor on a hospital-wide staffing dashboard even though it stops work at the department level. A single unfilled CT tech shift can back up an entire radiology schedule, and one missing respiratory therapist changes how an ICU night shift runs, but neither shows up as loudly in an executive report as ten open RN positions.

The Allied Health Roles Under the Most Pressure

Four roles account for most of the disruption hospitals report right now: radiology and imaging technologists, respiratory therapists, surgical technologists, and lab technicians. Each has its own bottleneck, but all four share the same underlying problem: too few credentialed graduates for too many open positions.

Radiology and Imaging Techs (CT, MRI, IR)

The radiology tech shortage is a training bottleneck, not a lack of interest in the field. Accredited radiologic technology programs graduate a fixed, limited number of students each year, and advanced modalities like CT, MRI, and interventional radiology require additional certification on top of the base credential. Many imaging departments report open CT and MRI tech positions sitting unfilled for 3 to 6 months, longer than a typical RN vacancy.

Respiratory Therapists

Respiratory therapist staffing tightened sharply after 2020 and has not loosened back to prior levels. Respiratory therapy programs are concentrated in a small number of community colleges, and many graduate fewer than 20 students a year, so one program shrinking its cohort can measurably shrink the regional supply.

Surgical Techs and Lab Techs

Surgical technologists and clinical lab technicians face a related supply problem from a different angle. Both roles require hands-on clinical rotations that many programs struggle to place, which caps how fast new graduates can enter the workforce. Hospitals in rural and mid-size markets often wait several months to fill a single surgical tech or lab tech opening, and some run short-staffed rather than leave the role vacant.

What Makes These Positions Harder to Fill Than Nursing

Allied health roles are harder to fill because the candidate pool is smaller and more specialized at every level, from school to license to shift. Nursing has hundreds of accredited programs nationwide feeding a large, flexible workforce that can often float between units. Allied health credentials do not work that way: a CT tech cannot cover an open lab tech shift, and a respiratory therapist license does not transfer to imaging.

• Fewer training programs: many allied health specialties are taught at a small number of schools, some producing fewer than 25 graduates a year in a given region.

• Certification stacking: advanced imaging and respiratory roles often require a base license plus one or more specialty certifications, which adds months to the pipeline.

• Narrow substitutability: staff in one allied health specialty typically cannot cover shifts in another, unlike float pools that work across nursing units.

The Real Cost of Unfilled Allied Health Positions

An unfilled allied health position costs a hospital more than the salary line, it costs throughput. When an imaging department runs short a tech, CT and MRI scan volume drops, which backs up ED discharges and delays surgical clearance for patients waiting on imaging.

Estimates for the fully loaded cost of a single allied health vacancy, including overtime, agency premiums, and lost procedure revenue, commonly run from $75,000 to over $150,000 a year depending on the specialty and market.

Respiratory therapist gaps carry a similar cost in a different form. Understaffed shifts increase overtime pay and raise the risk of care delays for ventilator and high-acuity patients, which pushes more of the workload onto the therapists who remain and accelerates burnout in the department that can least afford it.

Practical Strategies for Closing the Gap

Hospitals that close allied health gaps fastest treat the problem as its own staffing category, not a subset of nursing strategy. That means building a supply chain specific to imaging, respiratory, surgical, and lab roles instead of applying nursing recruitment tactics to a completely different candidate pool.

• Work with specialty-focused staffing agencies that maintain active pools of credentialed radiology, respiratory, surgical, and lab candidates, rather than general clinical staffing vendors.

• Cross-train where licensure allows, for example building a bench of techs certified in both CT and MRI, to add scheduling flexibility without waiting on new hires.

• Use per diem allied health coverage for predictable volume swings and short-term gaps, and travel allied health contracts for vacancies expected to last 8 weeks or longer.

• Forecast openings 60 to 90 days out given how long these credentials take to source, instead of starting the search the week a resignation is submitted.

Frequently Asked Questions

What is causing the radiology tech shortage?

The radiology tech shortage comes down to a training bottleneck: accredited imaging programs graduate a limited number of students each year, and advanced modalities like CT, MRI, and interventional radiology require extra certification beyond the base credential. Demand for imaging has grown faster than program capacity in most markets, so open CT and MRI positions often sit unfilled for 3 to 6 months.

Why are respiratory therapist vacancies taking so long to fill?

Respiratory therapy programs are concentrated in a small number of schools, many graduating fewer than 20 students a year, so the regional supply of new therapists is limited. Demand for respiratory support has stayed elevated since 2020, which means hospitals are competing for a candidate pool that has not grown to match it.

Can cross-training fix allied health staffing shortages?

Cross-training helps but does not fully solve the problem, since licensure limits how far a tech or therapist can move between specialties. Building staff certified in adjacent modalities, like CT and MRI, adds real scheduling flexibility, but it works best alongside agency support and longer-range forecasting.

Should hospitals use per diem or travel staff for allied health roles?

Both, depending on the gap. Per diem allied health coverage works well for predictable volume swings and short call-outs, while travel allied health contracts make sense for vacancies expected to last 8 weeks or longer while a permanent hire is sourced.
