Hospitals have more advanced technology than ever before. Artificial intelligence can analyse scans, robots can assist surgeons, and patient monitors can track vital signs continuously.
But hospitals still depend on something technology cannot easily replace: doctors and nurses.
In 2026, healthcare systems across the United States, United Kingdom, Canada and Australia continue to struggle with workforce pressure. The problem isn’t simply that too few people want healthcare careers.
An ageing population is increasing demand for treatment. Experienced clinicians are retiring. Burnout is pushing some workers away from bedside care. Training new doctors takes years. Nursing schools and clinical-placement programs have limited capacity. Rural hospitals struggle to recruit. And hospitals increasingly compete internationally for the same skilled professionals.
The result is one of the most important healthcare stories of 2026.
1. An Ageing Population Needs More Healthcare Workers
One of the biggest forces behind the shortage is surprisingly simple: people are living longer.
Older populations generally require more healthcare, particularly for chronic conditions such as heart disease, diabetes, cancer, dementia and respiratory illness.
The American Hospital Association’s 2026 Health Care Workforce Scan says US hospitals are confronting rising demand as the population ages and patient needs become more complex. At the same time, longstanding staffing shortages, turnover and burnout continue to pressure hospitals.
That creates a difficult equation:
More patients need care while hospitals struggle to expand their clinical workforce fast enough.
Emergency departments feel this particularly strongly. England recorded 2.46 million A&E attendances in May 2026, setting a record at the time.
More demand means hospitals need more nurses, physicians and support staff simply to maintain the same level of service.
2. America Could Be Short More Than 140,000 Doctors
The US workforce outlook shows how serious the long-term problem could become.
The American Hospital Association reported in 2026 that federal workforce projections indicate the United States could face shortages exceeding 141,000 physicians and 108,000 nurses by 2038 if current trends continue.
Another AHA analysis cites projections of more than 86,000 fewer physicians than needed by 2036, including shortages among primary-care doctors and specialists such as neurologists, radiologists, psychiatrists and pathologists.
3. Thousands Want to Become Nurses—but Training Capacity Is Limited
Perhaps the most surprising part of America’s nursing shortage is that a lack of applicants isn’t necessarily the main problem.
According to the AHA, US nursing schools rejected 80,162 qualified applications in 2024.
Why reject qualified people during a nursing shortage?
Nursing education requires more than classrooms.
Schools need qualified instructors, clinical-training sites and supervised placements in hospitals and other healthcare facilities.
If those resources are unavailable, programs cannot simply admit unlimited numbers of students.
4. Burnout Is Turning a Shortage Into a Retention Crisis
Recruiting healthcare professionals is only half the challenge.
Hospitals must keep them.
Healthcare workers have experienced years of high workloads, staff shortages, administrative demands and emotional pressure.
The AHA’s outlook for 2026 reports that 40% of nurses say they intend to leave their jobs or retire within five years, while more than 138,000 nurses left the workforce between 2022 and 2024.
The problem can become self-reinforcing.
When a hospital loses nurses, the remaining nurses may work more shifts.
Those heavier workloads can increase burnout.
More burnout can cause additional employees to leave.
And the hospital becomes even more understaffed.
5. Canada Has More Nurses—but Hospitals Still Feel Short-Staffed
Canada demonstrates why workforce shortages cannot be understood simply by counting the number of nurses.
Canadian Institute for Health Information data released in July 2026 shows that 238,162 registered nurses were working in direct patient care in 2025, an increase of 2% from the previous year.
Yet Canadian hospitals continue to report staffing pressure.
CIHI says hospitals are increasingly relying on overtime and private staffing agencies to cover gaps. More than half—52.5%—of job vacancies among nurses and allied-health professionals were advertised for 90 days or longer, compared with 31.6% across all occupations.
This highlights an important distinction.
6. The UK Has Doctors—but Not Enough Training Positions
The UK’s situation reveals another unusual workforce problem.
Thousands of doctors may want to continue their careers, yet there can be a bottleneck in accessing specialist training.
NHS England reported in June 2026 that 33,953 applications met the required standard for only 9,315 specialty-training posts.
To address the bottleneck, the NHS is planning up to 4,500 additional specialty-training places over three years, including 1,000 posts over the next year.
This means the phrase “doctor shortage” can be misleading.
A healthcare system may simultaneously have:
hospitals needing more experienced doctors,
while also having
young doctors competing intensely for the limited training positions needed to become those specialists.
Training a doctor takes many years, so fixing these bottlenecks cannot happen overnight.
7. Australia Could Need Nearly 80,000 More Nurses
Australia is also preparing for significant workforce pressure.
In August 2026, the Australian government released its National Nursing Workforce Strategy, warning that without reform the country could face a shortage of around 79,000 nurses by 2035.
Its modelling estimates an undersupply of 70,707 full-time-equivalent nursing positions, equivalent to approximately 79,473 individual nurses needed to close the gap.
The Australian government says demand is being driven by factors including an ageing population, more chronic and complex illnesses, geographic challenges and changing healthcare needs.
Jobs and Skills Australia has also identified both lengthy training requirements and retention problems as contributors to registered-nurse shortages. Workplace violence, inadequate staffing ratios and low professional satisfaction are among the factors potentially encouraging nurses to leave.
8. Rural Hospitals Have an Even Bigger Problem
Healthcare workers are not distributed evenly.
Large cities often contain major teaching hospitals, medical schools and specialist centres.
Smaller towns and remote regions may struggle to recruit surgeons, emergency physicians, nurses, mental-health professionals and other specialists.
The US AHA specifically identifies rural primary care and hospital medicine among areas where foreign-trained professionals help fill difficult vacancies.
Australia and Canada face similar geographic challenges because enormous areas of both countries have relatively small populations.
This means national workforce figures can hide major local shortages.
A country might technically have enough doctors overall while individual communities remain severely underserved.
9. Hospitals Are Increasingly Recruiting Internationally
One solution has been international recruitment.
The US, UK, Canada and Australia all depend to varying degrees on healthcare professionals who trained overseas.
But this creates global competition.
If the US offers better salaries to international nurses, Canada may find recruitment harder. If Australia attracts overseas doctors to regional areas, those clinicians are no longer available elsewhere.
International recruitment can fill immediate gaps, but it cannot be the only long-term solution.
Countries also need to increase domestic training capacity and retain the clinicians they already have.
10. Hospitals Are Turning to AI and New Staffing Models
Hospitals cannot instantly create thousands of additional doctors and nurses.
Instead, they are trying to make existing staff more productive.
The AHA says hospitals are increasingly experimenting with team-based care, AI, automation, virtual monitoring, new healthcare roles and redesigned workflows.
For example, AI medical scribes can automatically draft clinical notes, potentially reducing time doctors spend on documentation.
Hospitals are also expanding roles for nurse practitioners, pharmacists, physician assistants and other healthcare professionals.
Canada illustrates this trend.
CIHI reported that 8,611 nurse practitioners were providing direct patient care in 2025, up 10.2% in just one year.
The idea isn’t necessarily to replace doctors.
It is to ensure that every healthcare professional spends more time doing work that actually requires their expertise.
What Does the Shortage Mean for Patients?
Patients may notice the effects through:
longer emergency-room waits,
difficulty finding a family doctor,
longer waits for specialists,
delayed elective procedures,
shorter appointment times,
hospital-bed closures,
and greater use of virtual care.
But the shortage is not simply about hospitals failing to hire.
It is the result of several problems happening simultaneously: rising demand, burnout, retirements, limited training capacity, geographic inequalities and years-long medical education pipelines.
