The Global Doctor Shortage Is Changing Healthcare Faster Than Most People Realize

Who gets the doctors?

Healthcare systems across wealthy countries are increasingly drawing from the same international physician workforce.

OECD data show that member countries employed more than 600,000 foreign-trained physicians in 2023, an increase of just over 50% since 2010. Foreign-trained doctors represented an average of 20% of the medical workforce across OECD countries in 2023, up from 16% in 2010. OECD 2025

International recruitment can relieve an immediate staffing gap. It can also shift pressure from one healthcare system to another.

Physicians have become part of an international labor market

Doctors move for many of the same reasons other highly skilled workers move: compensation, working conditions, professional development, safety, family opportunity, specialization, and immigration pathways.

Health systems recruit for many of the same reasons employers recruit in any constrained labor market: vacancies are open now, while the domestic training pipeline takes years.

OECD describes foreign-trained recruitment as a way countries can expand the medical workforce quickly and at relatively low cost. The same OECD analysis warns that reliance on international recruitment can deepen shortages in countries of origin. OECD 2025

The World Health Organization makes a similar point from a global health-system perspective. WHO states that international migration and mobility of health workers have increased in volume and complexity and that poorly managed migration from low- and middle-income countries can exacerbate shortages and weaken source-country health systems.

Training capacity moves slowly

The United States illustrates the timing problem. The Health Resources and Services Administration says preparing a physician can take more than a decade of education and residency. HRSA currently projects an overall U.S. shortage of 141,160 physicians in 2038. HRSA

A health system facing vacancies this year cannot produce a fully trained physician this year by expanding medical school enrollment.

Medical education can grow. Residency capacity can expand. Scope-of-practice rules, team-based care, technology, and productivity changes can affect demand for physicians. Each response operates on a different timeline.

International recruitment therefore becomes attractive during the gap between immediate staffing pressure and long-term domestic workforce development.

Demand is rising while part of the workforce approaches retirement

The Association of American Medical Colleges projects a U.S. physician shortage of up to 86,000 by 2036 under its modeling scenarios. Its 2024 analysis identifies population growth and aging as major demand drivers. AAMC reported that 20% of the clinical physician workforce was age 65 or older and another 22% was between 55 and 64. AAMC 2024

The AAMC and HRSA projections are different estimates produced with different models, assumptions, and time horizons. They should not be treated as interchangeable counts. Together, they point toward the same planning problem: physician supply is under pressure while demographic demand rises and a substantial share of clinicians approaches retirement age.

The shortage is also about distribution

A national physician count can hide severe local shortages. Rural communities, underserved urban areas, primary care, psychiatry, and particular specialties can experience access pressure even when a country’s total physician supply appears comparatively strong.

International recruitment can improve staffing in a destination country without guaranteeing that physicians settle in the communities with the greatest need.

The same distribution problem exists globally. Countries with stronger currencies, higher compensation, more advanced facilities, or easier migration pathways can attract clinicians from places with fewer resources to replace them.

One country’s vacancy can become another country’s loss

WHO’s concern about unmanaged migration is rooted in that asymmetry. Training a physician requires years of public and private investment. When that clinician migrates, the destination system gains a trained professional without having carried the full cost and time of producing that workforce.

Migration can also benefit physicians and their families through higher income, safety, professional opportunity, and remittances. Source countries may benefit when clinicians return with new skills or when diaspora networks contribute expertise and capital.

The policy challenge is therefore broader than stopping migration. WHO’s framework focuses on managing mobility in ways that protect worker rights while reducing damage to health systems already facing shortages. WHO 2024

Competition for doctors changes the economics of healthcare

A constrained physician workforce affects compensation, recruitment spending, locum tenens use, scheduling, service-line expansion, and the ability of hospitals or clinics to maintain coverage.

Organizations with more money can offer signing bonuses, relocation packages, immigration support, research opportunities, technology, and lifestyle advantages. Smaller systems and lower-income countries may struggle to match those offers.

The competition is visible inside countries too. Major metropolitan systems can recruit from rural regions. High-paying specialties can pull graduates away from lower-paying fields. Private employers can compete with public systems. Every movement solves one staffing problem while potentially creating pressure somewhere else.

The workforce is moving faster than the training pipeline

The central constraint is time.

Patients need care now. Hospitals need coverage now. A physician takes years to train. Demographic change, retirement, migration, and burnout can alter supply faster than education systems can replace it.

That is why the global doctor shortage increasingly looks like a competition over allocation rather than a single worldwide headcount. The question facing health systems is how to build enough domestic capacity while participating in an international labor market without making already-fragile systems weaker.

Who gets the doctors will increasingly depend on who can train them, retain them, distribute them, and create working conditions that make clinicians willing to stay.
