Public health nursing has long stood at the intersection of clinical care and population health, blending rigorous medical training with comprehensive public health principles. Unlike registered nurses who traditionally provide bedside care within clinical environments, PHNs operate beyond hospital walls, engaging communities directly. Their work encompasses a complex array of tasks, including disease surveillance, emergency preparedness, policy advocacy, and community mobilization—functions that are vital for preventing illness and promoting wellness at the macro scale.

Heather Krasna, PhD, EdD, associate dean for Career and Professional Development at Columbia Mailman School, emphasizes that despite the specialized and highly defined nature of public health nursing, federal labor classification systems have yet to reflect these distinctions. Currently, all registered nurses, including PHNs, are subsumed under the same Standard Occupational Classification (SOC) code (29-1141). This umbrella grouping masks the significant differences in job functions, competencies, and contributions within nursing subfields, hinderings granular workforce analyses and policy interventions.

To illuminate these disparities, Krasna and her colleagues undertook a rigorous comparative investigation utilizing several sophisticated data sources. They examined findings from the National Sample Survey of Registered Nurses (NSSRN) and the Public Health Workforce Interests and Needs Survey (PH WINS), both robust national surveys that capture workforce characteristics and self-reported activities. Coupling these datasets with real-time job posting analytics from Lightcast—a vast, comprehensive database cataloging occupational demand—they were able to distill critical differences in duties, required skills, education levels, and compensation between PHNs and other registered nurses.

The results are striking. Public health nurses undertake community-level health assessments and continuous surveillance activities vital for early detection of emerging health threats. Their responsibilities extend to managing individual cases to either preempt or resolve health problems while coordinating care across multiple health and social service systems. PHNs serve as trusted communicators and educators within communities, translating complex health information into accessible education campaigns and interventions that resonate at the grassroots level.

Moreover, PHNs are deeply engaged in advocacy and partnership-building efforts, striving to influence policy in ways that address social determinants of health and promote equitable health outcomes. Their involvement extends critically to frontline response roles in public health emergencies, including outbreak investigations, disaster response, and preparedness activities. This multilayered scope illustrates how PHNs serve as vital linchpins within public health infrastructure, seamlessly integrating clinical expertise with population health strategies.

Despite their indispensable contributions, the monolithic occupational classification system obscures PHNs’ true workforce size, generating significant limitations in federal data collection and analysis. This impairs the ability of health departments and policymakers to monitor workforce shortages, assess compensation adequacy, or identify training and resource needs specifically within public health nursing. Consequently, strategic planning for addressing urgent and emerging health crises remains suboptimal.

Quantitatively, PHNs represent approximately 18 percent of the workforce in local health departments and 8 percent at the state health department level. They confront some of the most pressing public health challenges, including managing the opioid epidemic, addressing health impacts of climate-induced disasters, and leading chronic disease prevention initiatives. Their unique training and positioning empower them to serve as crucial agents in mitigating these complex, multi-faceted issues.

The study’s authors highlight the upcoming 2028 revision opportunity for the SOC codes as a critical juncture to enact this change. They urge federal agencies, including the Department of Labor, to incorporate a dedicated classification for public health nursing. Such recognition would enable comprehensive and precise workforce surveillance, ensuring that PHNs receive rightful acknowledgment, targeted resources, and equitable pay reflecting their specialized roles.

Implementing a distinct SOC code for PHNs would also catalyze academic and professional workforce development programs by clarifying the career pathways unique to this discipline. Enhanced visibility on labor market analytics would attract new entrants to the profession, reinforce retention, and support funding streams essential for sustaining a vibrant public health nursing workforce.

The implications of adopting a formal occupation code extend beyond internal workforce management. In the broader context of public health preparedness and response, accurately quantifying and supporting the PHN workforce will enhance national capacity to respond to future pandemics and health emergencies. It will also facilitate more nuanced research on workforce dynamics, linking nurse deployment to health outcomes with greater precision.

This pioneering research was led by Krasna alongside co-authors Isabella Patino and Sarika Karra from Columbia Mailman School of Public Health, and Jocelyn Leung from the University of Minnesota. The study was generously funded by the Centers for Disease Control and Prevention (CDC) and the Health Resources and Services Administration (HRSA), underscoring its significance to federal health initiatives.

Founded in 1922, Columbia University’s Mailman School of Public Health remains a leader in public health research and education, employing nearly 300 multidisciplinary faculty and educating over 1,300 graduate students worldwide. Its faculty work at the forefront of essential health challenges such as infectious and chronic diseases, environmental health, and public health preparedness—fields in which the distinct contributions of PHNs are increasingly indispensable.

For policymakers, academic administrators, and public health leaders, this study issues a clear and urgent call to action: formal recognition and classification of public health nurses are not merely administrative adjustments but critical steps to safeguard and enhance the nation’s public health infrastructure. As future health crises loom on the horizon, empowering this specialized workforce segment benefits all facets of society by reinforcing the foundational systems that protect and promote population health.

The analysis encompassed an extensive review of 79,743 primary care practices across the United States, revealing that a noteworthy 53.4% of these practices employed NPs in 2023. This statistic marks a dramatic increase from just 21% in 2012, signaling the growing acceptance and integration of NPs within the primary care framework. The rise in NP employment is not merely a statistical anomaly; it aligns with broader healthcare trends that indicate a shifting paradigm in how medical professionals deliver care.

The researchers meticulously examined how practices that include NPs differ demographically from those that do not. They discovered that such practices are disproportionately located in lower-income areas with a striking 23.3% of NP-employed practices situated there versus 17.2% without NPs. Additionally, rural communities also experience increased access, with 11.9% of practices with NPs serving these areas in comparison to 5.5% for practices without NPs. These findings emphasize the critical role NPs play in expanding healthcare access to populations that face geographical, economic, and educational barriers.

The socioeconomic profiles of the communities served by NP-employed practices reveal deeper insights into health disparities across the country. The study found that areas with NPs have higher percentages of individuals living below the poverty line—14.4% compared to 12.8% in non-NP practices. Moreover, the prevalence of residents without high school diplomas in NP-inclusive practices was 19.8%, higher than the 18.5% found in those without NPs. Such statistics paint a clear picture of how NPs contribute to addressing health inequities, particularly in regions where traditional medical professionals may be fewer.

As healthcare evolves, the need for NPs is increasingly crucial, particularly in light of the projected shortage of primary care physicians. With fewer medical residents opting for careers in primary care, the American healthcare system anticipates an alarming shortfall of between 20,200 and 40,400 primary care physicians by 2036. This gap presents an enormous challenge that requires immediate attention and strategic planning. The study’s findings serve as a poignant reminder of the need for policy initiatives aimed at both attracting and retaining NPs in underserved communities.

To adequately address these needs, the researchers advocate for comprehensive policies designed to bolster the presence of NPs in areas of greatest need. Recommendations include enhancing federal and state loan repayment programs as well as establishing pay parity in state Medicaid programs. Ensuring that NPs receive equal reimbursement across different payers will not only incentivize them to serve in underserved areas but also help to create a more stable and sustainable workforce in primary care.

The implications of these findings are broad-reaching, impacting not just the communities served by NPs but the overall structure of primary care across the nation. As healthcare systems continue to adapt to shifting demographics and needs, integrating NPs into care delivery models could provide a pathway to addressing some of the most critical challenges facing American healthcare. Strengthening the role of NPs offers a promising solution to improve health outcomes for vulnerable populations.

Effective nursing education and training will also play a pivotal role in sustaining this positive trajectory. The Columbia University School of Nursing, known for its commitment to health equity and bridging care disparities, emphasizes the importance of preparing nursing professionals who can effectively navigate the complexities of primary care today. Through rigorous academic programs and hands-on clinical experiences, future NPs will be equipped to address multifaceted health issues that patients face in diverse settings.

The research, funded by the National Institute of Nursing Research, illuminates the interconnected nature of socioeconomics, education, and health outcomes. The role of NPs extends beyond simply providing care; it encompasses promoting health literacy, preventive services, and comprehensive patient education in communities where such resources are scarce. As NPs continue to take on more significant roles, their influence will be vital in shaping public health policies aimed at reducing disparities.

The increasing presence of nurse practitioners in primary care highlights a transformative movement toward a more inclusive healthcare environment. By leveraging the unique skills and expertise of NPs, healthcare systems can better position themselves to meet the diverse needs of their populations. As this trend continues to grow, the overall health of communities—particularly those historically marginalized—stands to benefit greatly, paving the way for a healthier future that prioritizes accessibility and equity in care.

In conclusion, the research conducted by Columbia University serves as a clarion call for stakeholders within the healthcare sector. Policymakers, healthcare institutions, and education systems must collaborate to ensure that nurse practitioners are supported and their integral roles are made more pronounced within the primary care context. Emphasizing NP integration is not just beneficial for immediate healthcare access but serves as a long-term investment in the country’s health infrastructure, promoting a healthier, more equitable society for generations to come.
