The Healthcare Workforce Shortage of Nurses and Physicians: Practice, Theory, Evidence, and Ways Forward.

The healthcare sector is ubiquitously plagued by workforce shortages in economies around the globe. The fragility of this structural shortage becomes apparent when external shocks, such as the COVID-19 pandemic, exacerbate the lack of workers in clinical practice. In this article, we summarize current trends in healthcare workforce development across the globe, review theoretical concepts of workforce shortages, and discuss policies to address them. In practice, developed countries often address workforce shortages with targeted migration policies. However, targeted workforce migration policies only intensify workforce shortages in low-and middle-income countries. Theoretical macroeconomic models suggest that supply shortages may result from too low wages, supply lagging behind demand, and social perception. Changes in the wage rate cannot sufficiently increase the supply of health professionals as scholars find inelastic wages for physicians and nurses. Nonpecuniary factors such as working conditions, job satisfaction, and intrinsic motivation are at least equally important as financial incentives. In conclusion, increased wages can only be part of a heterogeneous policy plan to address shortages. Migration and retirement levels of health professionals can temporarily mitigate workforce shortages but rarely change the underlying systemic issues. Increasing the number of places available in medical and nursing schools while also improving, both, financial and nonfinancial incentives for employees are long-term structural policy options.
