Global Health: Evolution, Determinants, and the Role of DNP-Prepared Nurses

Posted on | by Linus

Global health has transitioned from a narrow focus on related tropical diseases and medicine to a more comprehensive, complex pursuit of health equity and the management of macrosocial determinants of health across borders. The evolution has been from the early 19th century, with international sanitary efforts focused on controlling infectious diseases and preventing epidemics that affected many people, such as cholera and plague, to a broader, equity-driven discipline addressing health.

Post-World War II, global health evolved into an international health system with the founding of what is today known as the World Health Organization (WHO) in 1948, marking a shift toward coordinated global action to improve the health of people and, by the late 20th century, emphasizing health as a fundamental human right. Global health adopted a broader focus on equity, social justice, and interdisciplinary efforts to address worldwide disparities. Over time, globalization, migration, climate change, and epidemiologic transitions expanded global health’s scope beyond communicable diseases to include noncommunicable diseases (NCDs), mental health, and health systems strengthening. These determinants underscore how poverty and education exacerbate disease burdens, guiding interventions for better population health

Health equity, transnational determinants, and shared responsibility are essential ideas in global health. These ideas are directly related to the worldwide burden of disease, which shows how social factors such as income, education, environment, and access to care can contribute to differences in health. Countries with less favorable economic situations disproportionately experience preventable morbidity and mortality due to limited resources, which affect the effective primary health system. In contrast, NCDs increasingly affect all regions, illustrating the interrelation of global health challenges. Focusing on determinants of health, such as poverty, food insecurity, and weak health infrastructure, is essential to reducing this burden and developing effective health plans.

Evaluating healthcare in this complex landscape requires more than just tracking clinical stats; it relies on population-level indicators, including morbidity, mortality, disability-adjusted life years, quality, access, and cost-effectiveness. Continuous evaluation informs policy decisions, guides resource allocation, and supports sustainable improvements in health outcomes. Evidence-based evaluation frameworks help ensure that interventions are culturally appropriate, equitable, and impactful. This analysis reveals gaps in resource allocation and informs policy for equitable care.

The Doctor of Nursing Practice (DNP) Essentials are critical to global health. Essentials I and III facilitate the translation of evidence into practice and the enhancement of quality. In contrast, Essentials II and VII underscore systems leadership and policy advocacy to tackle structural determinants of health and empower nurses to tackle global health issues through evidence-based strategies and advocacy. DNP-prepared nurses work together to improve global health by serving as leaders, conducting evaluations, and practicing in ways that are fair to everyone.

Step-by-Step Guide to Writing a Global Health Discussion

Step 1: Introduction

  • Introduce the evolution of global health, highlighting the transition from narrow disease control to a focus on equity and social determinants.

  • Define key terms: global health, health equity, macrosocial determinants.

Example Introduction:
“Global health has evolved from the 19th-century focus on controlling infectious diseases to a modern, equity-driven discipline addressing worldwide health disparities. Today, global health emphasizes health equity, social justice, and the management of macrosocial determinants, including poverty, education, and access to care.”

Step 2: Historical Evolution of Global Health

  • Discuss key milestones:

    • 19th century: international sanitary efforts, cholera, plague

    • Post-World War II: founding of the WHO in 1948

    • Late 20th century: focus on health as a human right, inclusion of NCDs, mental health, and health system strengthening

  • Highlight how globalization, migration, and climate change expanded the scope.

Example Paragraph:
“Initially focused on controlling epidemics like cholera and plague, global health expanded after World War II with the creation of the World Health Organization (WHO) in 1948, emphasizing coordinated global action. By the late 20th century, global health increasingly addressed health equity, social justice, and interdisciplinary collaboration to reduce worldwide disparities, including the growing burden of noncommunicable diseases (NCDs) and mental health conditions.”

Step 3: Social Determinants and Health Equity

  • Explain the influence of social factors on health outcomes: income, education, environment, and healthcare access.

  • Use examples: resource-limited countries, disproportionate morbidity/mortality, and emerging NCD burdens globally.

Example Paragraph:
“Health equity and transnational determinants are central to understanding the global burden of disease. Countries with limited resources face higher rates of preventable morbidity and mortality due to inadequate healthcare infrastructure. Meanwhile, noncommunicable diseases increasingly affect all regions, illustrating the interconnected nature of global health challenges. Addressing poverty, food insecurity, and weak health systems is essential to reducing disease burden and guiding effective health interventions (Marmot & Allen, 2014).”

Step 4: Evaluation and Evidence-Based Interventions

  • Discuss the importance of population-level indicators (morbidity, mortality, DALYs, quality, access, cost-effectiveness).

  • Explain how evaluation informs policy and resource allocation for sustainable improvements.

Example Paragraph:
“Evaluating healthcare globally requires more than clinical statistics; it relies on population-level indicators, such as morbidity, mortality, disability-adjusted life years, and cost-effectiveness. Evidence-based evaluation frameworks ensure interventions are culturally appropriate, equitable, and effective. These analyses reveal resource gaps and inform policy development for equitable care (World Health Organization, 2023).”

Step 5: Role of DNP-Prepared Nurses

  • Connect global health to DNP Essentials:

    • Essentials I & III: evidence translation and quality improvement

    • Essentials II & VII: systems leadership, policy advocacy, addressing structural determinants

  • Emphasize leadership, evaluation, and advocacy roles of DNP nurses in global health.

Example Paragraph:
“DNP-prepared nurses are pivotal in improving global health by translating evidence into practice, leading quality improvement initiatives, and advocating for structural changes that address social determinants of health. Essentials I and III guide evidence-based interventions, while Essentials II and VII empower nurses to lead systems-level improvements and policy advocacy to enhance health equity worldwide.”

Step 6: Conclusion

  • Summarize key points: evolution of global health, social determinants, evaluation, and DNP nurse roles.

  • Emphasize the importance of interdisciplinary, evidence-based, and equity-focused approaches.

Example Conclusion:
“In summary, global health has evolved into a complex, equity-driven discipline addressing both communicable and noncommunicable diseases worldwide. Understanding social determinants, evaluating population-level outcomes, and leveraging the leadership and expertise of DNP-prepared nurses are essential for advancing health equity and ensuring sustainable improvements in global health.”
