A global healthcare workforce crisis is on the horizon, with projections estimating a shortage of at least ten million healthcare workers by 2030. This shortfall poses severe risks not only to individual well-being but also to global health systems and economies. While expanding the workforce supply is crucial, it is no longer sufficient. The path forward demands a bold reimagining of who delivers care, how services are provided and where healthcare takes place. Through strategic investment and systemic innovation, the global community has an opportunity to not only avert millions of years lost to disease and disability but also unlock over €1.01 trillion ($1.1 trillion) in economic value.
Understanding the Healthcare Workforce Gap
The implications of the healthcare worker shortage are wide-reaching. Almost 60 percent of the global population lacks access to essential health services, a gap largely attributed to the insufficient number of trained professionals. The result is longer wait times, untreated chronic conditions and preventable deaths—especially in maternal and neonatal care. The impact is not evenly distributed: Africa, for instance, holds 17 percent of the global population yet shoulders over half of the workforce shortfall.
To categorise this complexity, countries fall into four archetypes: worker-scarce, worker- and job-scarce, worker-advantaged and worker surplus (although the last does not currently exist). Worker-scarce countries, including many in Latin America and the Middle East, face high job vacancies despite a shortage of professionals. In contrast, job-scarce countries, mostly in Africa, struggle with both insufficient workers and limited job availability due to economic constraints. Meanwhile, high-income countries like the United States and United Kingdom, although better staffed, still experience inefficiencies and unfilled positions, especially in rural or specialised roles.
Strengthening the Workforce Triangle
Addressing this crisis begins with what the McKinsey Health Institute calls the Healthcare Workforce Triangle: Grow, Thrive and Stay. Each strategy targets a different aspect of the healthcare labour ecosystem.
"Grow" refers to expanding the talent pipeline. Many countries face bottlenecks in educational infrastructure and faculty shortages. Solutions include opening new training sites, introducing flexible faculty roles and shortening programme durations through accelerated or digital formats. For instance, Brazil’s expansion of medical schools helped increase its primary-care physician base significantly. Similarly, accelerated nursing programmes in the United States and the UK have expanded capacity while maintaining quality.
"Thrive" focuses on freeing up healthcare workers’ time. Up to 30 percent of routine nursing tasks could be automated or delegated, allowing clinicians to spend more time with patients. Empowering community health workers and introducing new roles for informal care can improve efficiency. Additionally, AI and automation offer powerful tools to reduce administrative tasks and enhance decision-making. In some countries, AI-assisted documentation and computer-aided diagnostics have reduced workload and accelerated care delivery with promising results.

"Stay" aims to improve retention by addressing the root causes of attrition, such as workplace violence, burnout and poor recognition. Effective strategies include redesigning work environments, investing in staff well-being and embedding appreciation into organisational culture. Moreover, targeting rural and underserved regions through local recruitment and supportive infrastructure has proven to increase healthcare worker retention. Flexible child care, scholarships and required service periods are also strategies that have demonstrated effectiveness.
Reimagining Healthcare Service Delivery
Even with maximum implementation of the Grow, Thrive and Stay strategies, a significant gap would remain. Thus, a radical shift in care delivery is essential—transforming who provides care, how it is accessed and where it takes place.
The concept of "who" is expanding to include not just formal healthcare professionals but patients themselves. Enhancing health literacy from early education through adulthood empowers individuals to take a more active role in managing their well-being. This could include learning to self-administer medications or using digital diagnostics at home. Community-based care, supported by technology and better access to health information, could significantly ease pressure on overburdened systems.
"How" care is delivered must also evolve. The traditional model of waiting for symptoms before seeking help is unsustainable. Instead, early detection, preventive care and digitally guided self-management can become standard. Technologies such as AI can aid in triage and routine diagnosis, enabling timely intervention and reducing the need for high-acuity treatment.
Finally, "where" care occurs should move beyond hospitals and clinics. Embedding healthcare into daily life—through pharmacies, workplaces and even homes—creates more accessible, cost-effective entry points. Self-injectable medications and remote monitoring devices are already reshaping how chronic diseases are managed. Expanding these innovations could reduce unnecessary hospital visits and improve patient outcomes.
The global shortage of healthcare workers is not merely a supply challenge but a systemic one. Closing the gap requires coordinated action across education, employment, innovation and community empowerment. By embracing the Healthcare Workforce Triangle and reimagining care delivery, the world can not only meet the health needs of billions but also drive significant economic and social gains. This transformation demands urgency, creativity and sustained investment—but the potential rewards are immense: a healthier population, a more resilient workforce and a redefined future for healthcare worldwide.
