Global Shortage of Health Workers

Health Systems and Health Sectors

Health Systems and Health Sectors

A health system, also known as a healthcare system, refers to the organization of people, institutions, and resources that deliver healthcare services to meet the health needs of target populations. There are many types of health systems around the world along with many different organizational structures. However, health systems encompass both the direct care of individuals and the broader infrastructure necessary for health, such as public health interventions and the regulatory environment.

In comparison, a health sector is a subset of the larger system that includes the organizations, people, and actions whose primary intent is to promote, restore, or maintain health. This includes efforts to influence determinants of health as well as more direct health-improving activities. The health sector may include public health initiatives, health care facilities, health education programs, and more (Karliner et al., 2020).

Universal Health Coverage (UHC)

Universal Health Coverage (UHC) is a concept where all individuals and communities have access to needed health services without suffering financial hardship. It includes the full spectrum of essential, quality health services, from health promotion to prevention, treatment, rehabilitation, and palliative care. The World Health Organization (WHO) identifies UHC as a key goal for health systems (Udoh et al., 2020).

UHC would promote access to healthcare and medicines significantly compared to the present system globally. Currently, healthcare access is unevenly distributed, with wealthier countries and individuals within countries generally having better access to health services and medications. UHC aims to eliminate these disparities by ensuring that everyone, regardless of their ability to pay, has access to the services they need (Udoh et al., 2020).

In UHC, costs are usually covered through public financing mechanisms like taxes or social health insurance, reducing or eliminating the direct costs of healthcare at the point of service. This can prevent situations where people forgo necessary care because they can't afford it or face financial ruin due to high medical costs. The push for UHC recognizes health as a fundamental human right and an essential component of sustainable development (Udoh et al., 2020).

Global Shortage of Health Care Workers

There are actually many rationales that can explain the global shortage of healthcare workers. For one thing, the world's population is growing and aging, which increases the demand for health services. Aging populations often have more complex and chronic health needs, requiring more health workers to care for them. Another issue is urbanization: rapid urbanization has led to overcrowded cities and slums, making health services less accessible to some people and increasing the demand for health workers.

Other factors include the increasing burden of chronic diseases alongside infectious diseases, which is putting additional strain on health systems by putting existing health care workers in high demand. However, insufficient training and education in many parts of the world does not help the situation. Many countries do not have sufficient capacity to train enough health workers. Plus, health education opportunities are often unequally distributed, leading to shortages in underserved areas. When hospitals are established, working conditions are often poor and compensation is low. In various parts of the world, health workers often face challenging working conditions, including long hours, high stress, and low pay, leading to burnout and turnover. Thus, health professionals often migrate from low- and middle-income countries to high-income countries for better opportunities and working conditions, leading to "brain drain" in the countries that may need these workers the most. Addressing this shortage is critical for achieving UHC and improving health globally. Strategies should include improving health worker training and recruitment, offering incentives to work in underserved areas, and improving working conditions and compensation.
