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.
