Digital health encompasses technology-enabled services to advance patient health and well-being. Digital health includes the following: (1) telemedicine and telehealth, enabling patient and health care provider engagement through telephone and video; (2) digital tools, monitoring, aggregating, and sharing patient data with health care providers; (3) mobile health (mHealth), allowing patient access to health care information and expertise through applications for smartphones and tablets; and (4) health information technology, empowering providers to use algorithms and electronic health records (EHRs) to identify, order, and deliver health care services. Digital health has the potential to improve access to health information and expertise, permitting patients health care customization, cost reduction, and the opportunity to have access to omnichannel experiences that meet their medical and social needs.

India's healthcare landscape is undergoing a digital transformation, driven by government initiatives, policy reforms, and technological advancements. With a rapidly growing population and increasing demand for quality healthcare, digital health solutions are playing a crucial role in enhancing accessibility, affordability, and efficiency. Digital healthcare infrastructure in India is evolving to bridge the gap between urban and rural healthcare services, leveraging telemedicine, electronic health records (EHRs), and artificial intelligence (AI)-driven diagnostics.

The recent World Economic Forum (WEF) article highlights India's potential to become a global leader in digital health by building a resilient digital health ecosystem. The report emphasizes the role of public-private partnerships, the importance of interoperability, and the need for robust data governance frameworks. It underscores how India’s initiatives, such as the Ayushman Bharat Digital Mission (ABDM) and the Digital Health Incentive Scheme (DHIS), can set a global benchmark for digital healthcare transformation.

There is a progressive shift in community health, giving importance to cross sector collaboration, leadership in addressing health disparities, and data enabled strategies. This model is built on the previous public health models by positioning local health departments as chief strategists, improving partnerships beyond traditional healthcare service settings to improve population health outcomes.

Emphasis on leadership is a new trend in public health for workforce development. Leaders of public health are expected to act as coordinators, guiding initiatives that address the social determinants of health. For this we need a diverse workforce for policy development, communication, and data analysis to overcome modern health challenges. In addition to this we need cross sector collaboration as a crucial approach. Health and its outcomes are influenced by various factors such as transportation, education, and housing, we need to work alongside non- health sectors, allowing a comprehensive strategy that enhances the overall wellbeing of the community.

Another major trend is the increasing reliance on data driven decision-making. Advancement in analysis provides real time insights into emerging health issues, enabling us to achieve all target interventions and efficient resource allocation. In collaboration with modern technology, public health agencies can make more informed decisions to address disparities and improve health equality.

Innovative strategies play a very important role in public health such as digital health technologies, such as telemedicine, mobile health applications, and wearable devices, therefore enhancing and expanding healthcare access, particularly for underprivileged populations. These types of healthcare tools facilitate remote monitoring, personalized healthcare interventions, and patient engagement, resulting in better heath outcomes. Another innovative development is community dashboards, which provide data on health. These platforms are transparent, community participation, and accountability in addressing health concerns. A strong public health infrastructure necessary to respond to upcoming health threats, including environmental challenges and pandemics.

In conclusion, a transformative approach to community health, collaboration, innovation, and leadership. The model is to be embraced, communities can work toward achieving health equality and to improve overall health and wellbeing.

Public Health 3.0 emphasizes on addressing the social determinants of health such as education, employment , income, housing, transportation, food and economic stability.A large number of innovative communities across are already attempting to enhance health by positively affecting these determinants. Community leaders have formed alliances to raise educational attainment, advance economic opportunity, guarantee community safety, and create settings that support mental health and community involvement in places like Nashville, Tennessee; Manchester, New Hampshire; Harris County, Texas; and the Shoalwater Bay Indian Tribe in Washington.

In order to address health disparities, the Global Commission on Social Determinants of Health report suggested three essential action areas (World Health Organization: WHO, 2019).

Enhance the conditions of daily life:

 the situations in which individuals are born, develop, live, work, and age.

Address the structural causes of the unequal distribution of wealth, power, and resources (such as macroeconomic and urbanization policies and governance) 

Measure, comprehend, and evaluate the issue and the effect of a solution:

Develop a workforce that is skilled in the socioeconomic determinants of health, increase public awareness of these factors, and broaden the body of knowledge.

It is necessary to take more extensive and methodical action that is universal but appropriate to the disadvantages across the social gradient. This is required to effectively address health disparities and encourage healthier communities (World Health Organization: WHO, 2019).

In low- and middle-income nations, access to high-quality healthcare is still difficult to come by. Accessing primary care for timely and appropriate healthcare is most difficult for vulnerable people with unmet requirements. Digital technology utilization has the potential to increase access to healthcare, especially for the most vulnerable, while also fortifying health systems (Vasanthan et al., 2024).

According to a study,Virtual telehealth systems and mHealth apps that are integrated into smartphones or tablets were the most often utilized DHI for enhancing access to primary care. The included research conceptualized and employed digital health interventions for a variety of reasons. It served as a stand-alone tele-assistance to raise people's awareness and understanding of healthcare access and support for a range of medical issues. Another option for increasing and improving access to primary care was virtual primary health care, which supported general practitioners at the primary health level in blocks and districts by connecting them with the specialist or specialists in the hub or higher referral facilities (Vasanthan et al., 2024).

Era of Public Health 3.0 is considered as an evolutionary progress of public health towards innovation and transformation. Recent emphasis is laid on local governments to pioneer a new Public Health 3.0 model in which leaders can serve as Chief Health Strategists, leveraging data and resources to address social, environmental, and economic conditions that influence health and health equity (DeSalvo et al 2017). However, there could be key barriers in the adoption of Public Health 3.0 model. Since, such influential and impactful contribution in public health require effective leadership and management skills, one of the key barriers could be the building the leadership and management competencies among the public health workers nationwide (Fraser et al 2017). Secondly, although funding is usually stabilized, local health departments continue to face resource challenges from local financing streams, and proposals to reduce federal public health spending are likely to have a major impact at the local leve. Furthermore, the foundational framework of local governmental public health domain may itself act as a barrier to efficient and cost-effective coordination at the local level. Thirdly, the absence of non-proprietary tools for data, analytics and metrics, might leave actionable information out of reach for most localities (Fraser et al 2017). Thus, it can be said it is essential to address these key challenges so that all the communities can adopt Public Health 3.0 model and combat complex health challenges while prioritizing community engagement.

The era of Public Health 3.0 is an exciting time of innovation and transformation. With the Public Health 3.0 framework, we envision a strong local public health infrastructure in all communities and its leaders serving as Chief Health Strategists that partner with stakeholders across a multitude of sectors on the ground to address the social determinants of health. With equity and social determinants of health as guiding principles, every person and every organization can take shared accountability to ensure the conditions in which everyone can be healthy regardless of race, ethnicity, gender identity, sexual orientation, geography, or income level. If successful, such transformation can form the foundation from which we build an equitable health-promoting system — in which stable, safe, and thriving community is a norm rather than an aberration. The Public Health 3.0 initiative seeks to inspire transformative success stories such as those already witnessed in many pioneering communities across the country. The challenge now is to institutionalize this expanded approach to community-based public health practice and replicate these triumphs across all communities, for the health of all people.

Full List of Recommendations to Achieve Public Health 3.0 : 

Leadership & Workforce

• Public health associations such as Association of State and Territorial Health Officials (ASTHO) and National Association of County and City Health Officials (NACCHO) should develop best practice models and training for current public health leaders looking to work as Chief Health Strategists.
• The Health Resources and Services Administration (HRSA) should incorporate principles of Public Health 3.0 and social determinants of health in their workforce training programs, including the National Health Service Corps orientation, public health training center, and National Coordinating Center for Medicare and Medicaid Services Accountable Health Communities Model.
• Local public health agencies should partner with public health training centers and academic schools and programs of public health to inform training that meets the local public health workforce needs.
• The business and public health communities should jointly explore leadership development and workforce enrichment opportunities such as short-term fellowships or exchange programs, with a particular focus on the financial and operational capacity of local health departments.
• Academic institutions should encourage their faculty and administrations to develop meaningful partnerships with local public health departments and support service learning and internships for students from all disciplines in state and local health departments.
• Local health departments should train their leaders and staff in the concept and application of the collective impact model of social change.
• Public health should work with leadership institutes and business schools to establish professional development resources and opportunities.
  

Strategic Partnerships 

• Local public health agencies should form cross-sector organizational structures aimed at achieving a collective vision of community health that are capable of receiving and sharing resources and governance.
• The US Department of Health and Human Services (HHS) should work with others to develop a report defining the key characteristics of successful local public health models that address social determinants of health through cross-sector partnerships and recommending pathways to wide adoption.
• The Assistant Secretary for Preparedness and Response (ASPR) and the Centers for Disease Control and Prevention (CDC) should work with state and local health entities to ensure synchronization between health care practices, coalitions, and public health entities. Pre-crisis collaboration is essential to improve sharing of limited resources, improve timely and accurate communication, and improve sharing of data relevant to preparedness planning and response.
• Local public health leaders should create cross-jurisdictional organizational structures or partnerships for community development efforts.
• Public health entities should partner with environmental health agencies to address the environmental determinants of health.
• HHS should continue to develop tools and resources (such as the HI-5 [Health Impact in 5 Years]) that identify system-level drivers of health disparities, connecting health and human services, and work with communities to translate evidence to action.
• HRSA should recommend that health centers document collaboration with their state and/or local health department.
• Health care providers should identify clear mechanisms to engage with local public health as part of their effort to achieve the three-part aim of better care, smarter spending, and healthier people.
• The Centers for Medicare and Medicaid Services (CMS) and ASPR should work together to ensure state and local public health entities engage health care providers during times of crisis or disaster. Preparedness measures are essential to healthier and more resilient people.
• The Substance Abuse and Mental Health Services Administration should encourage state mental health and substance use disorder agencies and other grantees to collaborate with state, local, and tribal public health entities in achieving PH3.0 goals.
• The Agency for Healthcare Research & Quality should ensure linkages between primary care and public health via the Primary Care Extension Program and evaluate outcomes.
• The National Institutes of Health should continue its community participatory research and engagement efforts, such as the Clinical and Translational Science Awards and the Partnerships for Environmental Public Health, to accelerate translation of evidence to community action, as well as to generate new knowledge in the evaluation and implementation of public health interventions.
• Public health leaders should pursue local partnerships to ensure population health is central in all community development efforts.
  

Infrastructure and Accreditation

• HHS should assess opportunities to incentivize Public Health Accreditation Board (PHAB) accreditation through federal programs and policies.
• HHS should require state and local health departments receiving federal grants to indicate their PHAB accreditation status, including applications in progress or plans to apply in the future.
• The federal government should partner with the private sector to create a learning community for local health departments seeking to engage in PH3.0 work with a particular focus on collective impact models to address the social determinants of health.
• Resources to support the accreditation process and maintenance should be more readily available from public and private funding sources.
• PHAB should continue to evolve accreditation expectations by incorporating Public Health 3.0 concepts.
• Philanthropic organizations supporting local public health activities and social interventions should require grant applicants to collaborate with local health departments.
• ASTHO and NACCHO should accelerate their support of state and local health departments moving to accreditation.
• PHAB and its strategic partners should continue to enable pathways to accreditation for small and rural health departments.
• States should assess the efficiency and effectiveness of their local health departments, including addressing jurisdictional overlaps and exploring opportunities for shared services mechanisms.
  

Data, Metrics, and Analytics  

• HHS should utilize opportunities such as Healthy People 2030, NCVHS’s population health subcommittee, the Evidence-Based Policymaking Commission, and the census to elevate metrics related to social determinants to be leading health indicators, to define community-level indicators that address the social determinants of health and to explore models to leverage administrative data.
• NCVHS should advise the secretary of HHS to incentivize the integration of public health and clinical information.
• CDC should continue its work with the private sector to make subcounty-level data including health, health care, human services, environmental exposure, and social determinants of health available, accessible, and useable.
• HHS should work with public health leadership and the private sector to develop a nonproprietary tool to support geographic information systems and other analytic methods for front-line public health providers.
• Health systems and other electronic health data repositories should prioritize data sharing at the federal, state, and local level with the goal of achieving a learning health system inclusive of public health by 2024 as described in the Office of the National Coordinator for Health Information Technology (ONC) Nationwide Interoperability Roadmap.
• The HHS Office for Civil Rights should continue to develop guidance for the public health system to provide clarity on private and secure data use, as well as guidance to promote civil rights compliance to address those social determinants which are the product of discriminatory practices.
• ONC and the Administration for Children and Families should continue to establish clear data and interoperability standards for data linkage between health and human services sectors.
• HHS should continue to identify gaps in the collection of data relating to race/ethnicity, language, gender identity or sexual orientation in existing surveys. When feasible, governmental and nongovernmental stakeholders at all levels — federal, state, local, and tribal — should collect standardized, reliable data concerning disparities.
• HHS should facilitate linking environmental and human services data to health.
  

Sustainable and Flexible Funding

• The CMS and private payers should continue to explore efforts to support population-level health improvements that address the social determinants of health.
• HHS should explore transformation grants for state and local health departments to evolve toward PH3.0 structure, analogous to the State Innovation Model (SIM) grants to support health care system transformation.
• State governments receiving funds through SIM or Medicaid Waiver processes should be required to document their health department accreditation status and their strategies for addressing the social determinants in partnership with their local public health departments.
• States should maximize their use of the funding through the Health Services Initiative option under the Children’s Health Insurance Program to advance their public health priorities for low-income children.
• HHS should enhance its coordination both within the department and with other agencies, developing and executing cross-agency efforts to strategically align policies and programs that address the social determinants of health.
• Public and private funders should explore options to provide more flexibility for accredited health departments to allocate funds toward cross-sector efforts including partnership development and collective impact models in addressing the social determinants.
• Communities should examine how to best use the Affordable Care Act’s community benefits requirement for nonprofit hospitals by coordinating the alignment of the data collection process and pooling resources and how these can be used to advance and provide funding for public health.
• Public health agencies and academic institutions should periodically calculate the funding gap — the difference between the costs of providing foundational capabilities by each local health department and its current funding level — and communicate these figures in the context of forging partnerships and expanding funding sources.

Our collective efforts as a society to create the conditions necessary for everyone to be healthy are known as public health. Government public health is a crucial component, even though numerous sectors play important roles. A new Public Health 3.0 model, in which leaders act as Chief Health Strategists, collaborating across various sectors and utilizing data and resources to address social, environmental, and economic factors that impact health and health equity, is being pioneered by numerous local governments due to recent public health stressors. The Public Health 3.0 effort was started by the US Department of Health and Human Services in 2016, and listening sessions were held all around the nation. The main conclusions from those listening sessions are outlined in this article along with suggestions for achieving Public Health 3.0.
