Global Health and Population-Based Nursing Practice

Introduction

As healthcare challenges continue to evolve and impact populations on a global scale, advanced practice nurses and nursing leaders play a crucial role in addressing a range of health issues — from epidemics and disasters to global health gaps and health education. This paper explores various topics related to nursing practice in response to health challenges. Specifically, it focuses on the changing American demographic landscape, the impact of the United Nations Millennium Development and Sustainable Development Goals on population-based global health, efforts to empower people to control disease through health education, current strategies that address American national security and global health, and the role of the nursing leader in developing guidelines for disaster management and emergency preparedness that address population health.

The Changing American Demographic and Its Impact

The changing American demographic landscape has significant implications for health both domestically and internationally. In the United States, the aging of the Baby Boomer generation is putting increasing pressure on healthcare systems to address chronic conditions such as diabetes, heart disease, and Alzheimer's disease (Thomas, 2022). At the same time, the country is becoming more diverse, with increasing numbers of individuals from ethnic and racial minorities, many of whom experience disparities in health outcomes due to social determinants of health such as poverty, limited access to healthcare, and discrimination (Chang, 2019).

These trends also have implications for global health. As the United States becomes more diverse, its population includes more individuals who may have family and social ties to other countries (Curley, 2019). This means that the health of people in other countries can have a direct impact on the health of Americans. For example, a pandemic like COVID-19 can easily spread across borders and affect populations in multiple countries. The global health gap — the disparity in health outcomes between developed and developing countries — is often driven by factors such as poverty, limited access to healthcare, and lack of education (McNeely et al., 2020).

In the context of the COVID-19 pandemic, the changing American demographic landscape and the global health gap present significant challenges for organizations that provide healthcare for employees and their families in countries with limited healthcare access and health literacy. In the absence of a vaccine, preventing the spread of COVID-19 requires implementing public health measures such as social distancing, hand hygiene, and wearing masks. These measures can be difficult to implement in communities with limited access to healthcare, as well as in communities where people are more likely to hold jobs that require them to work in close proximity to others (Curley, 2019).

Given the limited funding available to address the COVID-19 pandemic, organizations may need to prioritize their efforts and resources toward areas where the disease is most prevalent or where the risk of transmission is greatest. This may require working with local communities to educate them about the importance of public health measures and to develop strategies to implement those measures in ways that are culturally appropriate and accessible to all community members. It may also require working with local governments and healthcare providers to ensure that resources are available to treat individuals who become infected.

Ultimately, addressing these challenges will require a multi-faceted approach that includes education, outreach, and collaboration with local communities, governments, and healthcare providers (Kim et al., 2022).

Efforts to Use Health Education to Empower People to Control Disease

Efforts to empower people to control disease through health education have been a critical component of public health interventions for many years. The underlying premise is that by educating people about the risks and prevention of infectious diseases, individuals can take steps to protect themselves and their communities.

While health education can be an effective tool in preventing and controlling disease, there are important limitations and challenges to consider. One of the main challenges is that simply providing information may not be sufficient to motivate behavior change (Finset et al., 2020). Many factors influence health behaviors — including social, cultural, and economic factors — and telling people what they should do may not be enough to overcome these barriers.

Another challenge is that not all individuals have equal access to health education and information. Individuals who are marginalized, such as those living in poverty, may not have access to the same resources as those who are more privileged, and may therefore be at greater risk for infectious diseases (Curley, 2019). This inequity can contribute to health disparities, in which certain groups are disproportionately affected by disease.

In addition, health education interventions may not be effective if they are not tailored to the specific needs and preferences of the target population. Different populations may hold different beliefs, values, and cultural norms that shape their perceptions of health and disease. Interventions that are culturally sensitive and adapted to the local context are therefore more likely to be effective in promoting behavior change (Moore et al., 2021).

Finally, efforts to empower people through health education may be constrained by structural factors such as lack of access to healthcare and social determinants like poverty, housing conditions, and food insecurity. These factors contribute to the spread of infectious diseases, and addressing them may require broader structural and policy interventions.

Thus, while health education is an important tool for preventing and controlling disease, it is not a panacea. To be effective, health education interventions must be tailored to the specific needs and preferences of the target population and integrated into a larger, comprehensive approach that addresses the social, economic, and structural factors driving the spread of infectious diseases.

Current Strategies Addressing American National Security and Global Health

Current strategies that address American national security and global health are closely intertwined, as global health threats have the potential to pose significant risks to national security. The United States has implemented several strategies that focus on a range of activities — from improving disease surveillance and detection to enhancing emergency preparedness and response — while also promoting stability and security in partner countries.

One such initiative is the Global Health Security Agenda (GHSA), an international partnership of over 60 countries, international organizations, and non-governmental organizations that seeks to strengthen global health security by enhancing countries' capacity to prevent, detect, and respond to infectious disease threats (Guthrie et al., 2019). The GHSA includes activities such as strengthening disease surveillance systems, improving laboratory capacity, and enhancing emergency response.

The National Biodefense Strategy is a U.S. government strategy that aims to enhance the nation's ability to prevent, detect, and respond to biological threats, including infectious diseases that have the potential to be used as bioweapons. The strategy encompasses activities such as improving disease surveillance and detection, advancing medical countermeasure development, and strengthening public health emergency preparedness.

The President's Emergency Plan for AIDS Relief (PEPFAR) is a U.S. government initiative that provides funding to support the prevention, treatment, and care of HIV/AIDS in over 50 countries, with a particular focus on sub-Saharan Africa. PEPFAR aims to address the global health threat posed by HIV/AIDS while also promoting stability and security in partner countries (Sexton et al., 2020).

The Global Health Initiative is a U.S. government effort to coordinate and integrate U.S. global health programs and resources in order to improve health outcomes in partner countries. The initiative focuses on key areas including maternal and child health, HIV/AIDS, malaria, and neglected tropical diseases.

Finally, the One Health approach recognizes the interconnectedness of human, animal, and environmental health and seeks to address health threats through a multi-sectoral, collaborative strategy. This approach acknowledges that health threats can originate from a range of sources — including infectious diseases, environmental hazards, and bioterrorism — and therefore requires a broad-based response involving public health, veterinary, and environmental professionals.

Conclusion

As healthcare challenges become increasingly complex and impact populations on a global scale, advanced practice nurses and nursing leaders play a critical role in addressing these challenges. From developing guidelines for disaster management and emergency preparedness to assessing and monitoring the health needs of communities affected by epidemics, the nursing profession has a key role to play in promoting population health and well-being. By prioritizing assessment, education, collaboration, treatment, and advocacy, nursing leaders and advanced practice nurses can help ensure that healthcare facilities and their staff are prepared to respond to a range of health challenges — from epidemics and disasters to global health gaps and health education. Through ongoing research, education, and collaboration, the nursing profession can continue to play a vital role in promoting population-based health and improving health outcomes for individuals and communities around the world.
