The World Health Organization has identified a persistent global shortage of nurses, with low- and middle-income countries hit hardest by the gap between the nurses they need and the nurses they can train, employ, and keep. While the global nursing workforce has grown in recent years, that growth is unevenly distributed, and the shortage continues to threaten health outcomes in dozens of countries worldwide.
Where the Shortage Is Worst
The nursing shortage is not spread evenly across the globe. Wealthier nations generally have enough training programs, competitive salaries, and infrastructure to maintain their nursing workforces, though many still face regional gaps. The real crisis sits in low- and middle-income countries, where health systems struggle to graduate enough nurses, create funded positions for them, and then retain them once they’re trained.
The WHO maintains a “health workforce support and safeguards list” of 55 countries where the nursing and broader health workforce is so fragile that active international recruitment is discouraged. These are nations where losing even a small number of nurses to wealthier countries can destabilize local health services. The list is meant to protect these countries, but it doesn’t solve the underlying problem: there simply aren’t enough resources to build and sustain a domestic nursing workforce at the scale populations require.
What’s Driving the Gap
Several forces are compounding the shortage simultaneously. Populations are aging in nearly every region, which increases the demand for nursing care at the same time that many experienced nurses are reaching retirement age themselves. The pipeline of new graduates hasn’t kept pace in many countries, particularly where nursing education programs lack funding or clinical training sites.
Retention is arguably the bigger challenge. Nurses leave the profession because of burnout, inadequate pay, unsafe working conditions, and limited opportunities for career advancement. The COVID-19 pandemic accelerated these pressures dramatically. Nurses on the front lines faced extraordinary physical and psychological demands, and many chose to leave healthcare entirely rather than continue under those conditions. Even in countries where workforce numbers have technically recovered, the experience and institutional knowledge lost during that wave of departures hasn’t been replaced.
International migration also plays a significant role. Nurses trained in lower-income countries are actively recruited by wealthier nations offering higher salaries and better working conditions. This creates a cycle where the countries that can least afford to lose nurses are the ones losing them fastest.
Why Staffing Levels Directly Affect Patient Safety
The nursing shortage isn’t an abstract workforce statistic. It has measurable consequences for people receiving care. A large observational study published through the UK’s National Institute for Health Research found that every additional hour of registered nurse care per patient was associated with a 3% reduction in the risk of death. The inverse was equally stark: for each day a patient spent on a ward where nurse staffing fell below the planned level, their risk of death increased by 9%.
Heavy reliance on temporary or agency nurses, a common stopgap when permanent staff are in short supply, also carries risk. Patients who experienced high levels of temporary nurse staffing saw a 12% increase in their risk of death compared to those cared for by permanent staff. Temporary nurses may be fully qualified, but they’re less familiar with ward routines, equipment, and individual patients. The data makes a clear case: stable, adequate nurse staffing saves lives, and shortages cost them.
Beyond mortality, each additional hour of registered nurse time per patient over the first five days of a hospital stay was associated with a 2% decrease in the likelihood of an adverse event, things like medication errors, falls, or infections that go unnoticed when nurses are stretched too thin.
Gender, Pay, and Workforce Composition
Nursing remains a predominantly female profession, and that demographic reality intersects with the shortage in important ways. The profession has historically been undervalued in part because of its association with women’s work, and pay has reflected that. In the United States, male nurses earn an average of roughly $79,700 per year compared to about $73,100 for female nurses, a gap of about 8%. That gap narrows considerably among nurses with specialty certifications, where the difference drops to around $1,250, but it persists across the broader workforce.
The proportion of men entering nursing is growing. Among nurses licensed before 2000, about 5.8% were male. Among those licensed between 2013 and 2015, that figure jumped to 14.1%. A more gender-diverse workforce could help expand the pipeline of new nurses, but only if the profession addresses the compensation and working conditions that drive people of all genders away from bedside care.
WHO’s Policy Framework for Closing the Gap
The WHO’s Global Strategic Directions for Nursing and Midwifery lays out four policy areas that countries need to invest in simultaneously to build a sustainable nursing workforce: education, jobs, leadership, and service delivery.
- Education means expanding and improving nursing training programs, including clinical placements and faculty development, so countries can graduate more nurses who are prepared for modern healthcare demands.
- Jobs focuses on creating funded, permanent positions with competitive pay and safe working conditions. Training nurses means little if there are no positions waiting for them, or if the positions that exist don’t pay enough to live on.
- Leadership calls for placing nurses in decision-making roles within health systems and governments. When nurses have a voice in policy, workforce planning tends to better reflect the realities of clinical care.
- Service delivery involves redesigning how care is organized so that nurses can work to the full scope of their training, rather than being limited to narrow tasks or bogged down by administrative burdens.
The framework recognizes that no single intervention will solve the shortage. Countries that invest heavily in training but don’t create jobs will simply export their graduates. Countries that raise salaries but don’t address burnout and unsafe conditions will continue losing experienced nurses mid-career. The WHO’s position is that all four areas need simultaneous attention, and that low- and middle-income countries in particular need to raise domestic investment rather than relying on international aid or recruitment from elsewhere.
What the Shortage Looks Like Going Forward
The trajectory is concerning but not locked in. Global nursing numbers are growing, just not fast enough or in the right places. The 55 countries on the WHO’s safeguards list represent the most vulnerable health systems, but workforce pressures are felt in emergency departments and rural clinics in wealthy nations too. Aging populations will continue to increase demand for nursing care over the next decade, and without structural changes to how nurses are trained, employed, and supported, the gap between supply and need will widen further.
The core challenge is that nursing shortages are systemic, not accidental. They result from decades of underinvestment in the workforce that delivers the majority of hands-on healthcare worldwide. Fixing them requires sustained political commitment and funding at a level most countries have not yet demonstrated.
