A groundbreaking perspective on the public health workforce has emerged, advocating for a broader and more inclusive definition. This new approach moves beyond conventional boundaries to encompass professionals from various sectors who contribute significantly to public health initiatives. According to Dr. Heather Krasna, associate dean at Columbia University Mailman School of Public Health, the traditional model of defining the workforce by job titles or government affiliations is no longer sufficient in today's complex health landscape. Instead, the focus should shift to understanding the impact of work rather than its source.

Dr. Krasna outlines a two-tiered framework that categorizes the public health workforce into distinct groups. The first tier consists of individuals employed directly by federal, state, local, tribal, and territorial health departments. The second tier includes professionals across diverse industries who dedicate at least half of their time to delivering services aligned with the Centers for Disease Control and Prevention’s Essential Public Health Services or Foundational Public Health Services. By adopting this intersectional framework, researchers and policymakers can better grasp the extensive network of professionals contributing to public health, ensuring more effective support systems.

This innovative redefinition not only enhances our understanding of the workforce but also paves the way for improved assessments, training programs, and resilient health systems. By recognizing contributions from both within and outside government agencies, we gain valuable insights into potential inefficiencies or gaps in service delivery. Such an approach ensures that essential public health services remain robust and adaptable, particularly during crises or pandemics. Embracing a comprehensive view of the workforce empowers us to build stronger, more responsive systems capable of addressing future challenges.
