Modernizing Data Systems in Environmental Public Health: A Blueprint for Action
Governance and Security Data governance provides the policies, standards, and oversight needed to man - age information ethically and effectively. Without strong governance, even the most advanced systems can falter due to confusion over data ownership, stew - ardship, or use. Clear governance practices ensure that data are protected, used appropriately, and aligned with agency goals and legal requirements. Governance responsibilities vary based on the size and structure of the EPH agency or department. In larger agencies, such as state health departments, governance is typically handled by dedicated teams that might include chief data officers, data stewards, privacy officers, and IT security leads. These organiza- tions often have formal data governance boards or committees to ensure coordi - nation and policy alignment across programs. In mid-sized local health departments, governance might fall to an IT or data manager, with responsibilities shared between program leads who oversee data collection and central staff managing access and security. In smaller or rural de- partments, program managers or directors often oversee governance informally, sometimes with support from general IT personnel or state-provided platforms that include built-in compliance tools. Regardless of the structure, all agencies benefit from a clear framework for data stewardship, consistent access controls, and the ethical use of data. Key compo- nents of sound governance include: Clearly defined roles and responsibilities for data collection, maintenance, access, and quality assurance Regular audits and reviews to evaluate data accuracy, integrity, and usage Security protocols such as encryption, multifactor authentication, and tiered permissions Compliance with legal frameworks , including HIPAA, public records laws, and relevant state-level privacy statutes Change management processes to guide and support system modifications over the lifetime of system use, ensuring continuity, user adoption, and align - ment with evolving needs
A Data-Centric Culture Technology alone cannot modernize EPH. Agencies are encouraged to support a workforce that understands and values data. This process requires a cultural shift toward data-informed thinking, backed by investments in professional de- velopment, cross-training, and the capacity to connect data to real-world impact through data-centered storytelling and policy analysis. Continuous training ensures staff at all levels receive regular, role-specific instruction on data systems, analytics tools, and visualization techniques. This training builds foundational skills and confidence in using modern tools. Effective training equips staff to translate analytical findings into persuasive narratives and policy recommendations, supporting accuracy and impact in decision- making and action. Internal champions play a crucial role in bridging the gap between technical and programmatic work. Identification and support of data champions within each team allow agencies to foster peer learning and encourage sustained engage - ment with data. These champions can model how to frame technical findings into stories that resonate with decision-makers and communities, and how to align data insights with regulatory and policy priorities. Celebration of success helps reinforce a culture of data use. The sharing of data-driven improvement stories, whether in compliance rates, community en- gagement, or resource allocation, not only demonstrates the practical value of modernization but also builds morale and broader buy-in across teams. A strong data culture fosters innovation, enhances morale, and empowers staff to adapt to emerging technologies confidently. When data moderniza- tion efforts are anchored in these core principles—FAIR data practices, re - al-time access, standardization, usability, governance, workforce readiness, data-centered storytelling, and policy analysis—EPH agencies can ensure their investments lead to more responsive, equitable, and sustainable public health systems. These principles provide the scaffolding on which agencies can build sound data infrastructures that are prepared for not only today’s needs but also tomorrow’s uncertainties.
