Damian Jacob Sendler: According to experts, public health primarily focuses on the health of the population as a whole, rather than individual health activities. They also adopt a population health approach, taking into account various factors such as genetics, behavior, and socio-economic conditions like housing, social networks, and education that can impact health and overall well-being. The incorporation of determinants of health has resulted in a paradigm shift towards comprehending health holistically and acknowledging the role of public health in promoting the health of the populace [3]. Public health’s crucial role in safeguarding and promoting health has frequently been overshadowed by debates on healthcare reform, except during major global health crises like the Ebola and Zika outbreaks. This is according to sources [4,5]. When it comes to health and the healthcare system, many individuals tend to associate it with clinics and hospitals. In North America, particularly in the United States and Canada, medical care is the biggest expense in the health budget. As a result, there is a lack of public or political enthusiasm for enhancing or funding public health systems. This is not unexpected, as medical care is a top priority for both countries. Despite ongoing budget cuts and insufficient investment in public health infrastructure, there is a lack of evidence regarding the state of public health systems in Canada and how they compare to other countries. This raises concerns about the overall health of the Canadian population. Public health research has primarily concentrated on assessing programs that target individual or population-level interventions and comprehending the causes and patterns of risk of illness and disease. However, it has not adequately addressed broader inquiries about the organization, delivery, or funding mechanisms of public health systems. In the midst of the ongoing COVID-19 pandemic, it is essential to comprehend the functioning of public health and broader health systems.
According to recent research, public health is not being given the recognition it deserves as a crucial aspect of health systems by health services and system researchers. Despite the significant contributions made by public health initiatives, including the control of communicable and non-communicable diseases, these achievements are frequently attributed to primary healthcare services and biomedical interventions. Despite the presence of various health systems frameworks that outline the constituent elements, operations, and objectives of healthcare systems, a uniform and unambiguous definition of public health systems has yet to be established, as per sources [13, 14].
Damian Sendler: The definition of public health systems is crucial in shaping the design and delivery of programmes and services that promote public health within the broader healthcare system and other significant institutions. This can pave the way for further discussions on the interplay between public health and healthcare. In a crucial move, this paper has tackled a pressing research area that demanded the creation of a comprehensive framework outlining the fundamental components of public health systems, as previously identified by experts [3, 15, 16]. A comprehensive analysis of existing literature was conducted to explore the definition and categorization of public health systems, as well as the distinctions between healthcare systems and public health systems within recognized frameworks for health systems.
According to the synthesis, the lack of a clear definition for public health systems can be attributed to two main factors: firstly, the concept of public health systems has been approached from different perspectives, and secondly, there is a certain degree of terminology overlap with publicly funded healthcare systems. The lack of clarity surrounding definitions and the evolution of terminology over time may also be attributed to the preferences of funders and publishers. Despite extensive research, no all-encompassing public health system frameworks were found. However, there was a notable focus on delineating the crucial responsibilities and duties of public health. The lack of consensus on essential functions across jurisdictions has made comparisons difficult. Public health services are often forced to take on responsibilities that fall outside the purview of healthcare systems, which can exacerbate financial constraints on already stretched budgets. Public health systems have taken the lead in responding to health emergencies due to their extensive capacity and expertise in organizing and addressing large-scale health threats. According to our findings, although several aspects of public health systems fall under the purview of conventional healthcare systems in terms of governance, delivery, and financial arrangements, there are significant distinctions, particularly with regard to the significance of partnerships and communication in public health. Partnerships have been instrumental in enabling multi-sectoral collaboration and promoting effective communication and information sharing to achieve the fundamental objectives of public health. In this paper, a framework for public health systems is proposed.
According to experts, there is a compelling argument to be made that public health and healthcare are aligned in their objective of promoting the well-being of individuals within larger communities. Integration, the convergence of public health and healthcare, is thought to facilitate the unification of the two systems to offer a smooth service delivery within the wider health system that caters to the requirements of both individuals and communities [33, 65]. The development of integrated health systems poses a challenge in terms of aligning financial, governance, and delivery arrangements to achieve complementarity and positive health outcomes. According to experts, population health is no longer limited to the health system alone, but encompasses political, environmental, and societal factors. Therefore, it is crucial to comprehend these broader contexts in which health systems function. This understanding can aid in improving overall population health outcomes. The current fit of public health systems within health systems has significant implications, with two key ramifications. Integrating healthcare and public health may prove to be a challenging task, as their objectives, management, funding, and provision of services are frequently misaligned. The prospect of integration between healthcare systems appears to be contingent upon substantial incentives, and even then, the absence of a unified vision for healthcare may hinder collaborative efforts. Public health experts have expressed concern that their ability to shape healthy public policies may be hindered if they are not included in decision-making processes for policies that fall outside of their field. This could have significant implications for public health initiatives. Debates may arise regarding the feasibility and desirability of the matter, but it can be argued that the current paradigm and structures are inadequate for achieving population health, which includes the wider social determinants of health.
Damian Jacob Sendler: Investing in public health systems is a crucial step towards improving population health and reducing healthcare costs in countries where medical care accounts for a significant portion of the health budget. It is imperative for governments and policymakers to acknowledge the significance of public health systems and provide sufficient resources to sustain them. Investing in public health infrastructure, such as surveillance systems, laboratories, and workforce development, is crucial to enable early detection and rapid response to disease outbreaks and other health emergencies. There is a growing need to shift the focus from treating illnesses to preventing them. Achieving this goal requires the implementation of evidence-based public health interventions and policies that target the social determinants of health, including education, housing, and employment. Moreover, it is imperative for public health systems to work in conjunction with other sectors such as education, housing, and transportation to tackle the root causes of health disparities and foster health parity. A comprehensive framework that outlines the crucial components, functions, and objectives of public health systems is imperative to provide guidance to policymakers, practitioners, and researchers in their efforts to enhance and invest in public health systems. By placing public health at the forefront and allocating resources towards robust public health systems, nations can enhance the overall health of their citizens and ultimately lower healthcare expenditures over time.
Improving the delivery of public health services to the population is crucial for strengthening public health systems. Innovative technologies and evidence-based practices are key to enhancing the effectiveness, efficiency, and quality of public health services. Investing in the education and training of public health professionals is crucial to ensure a proficient and capable workforce that can adeptly tackle both present and future public health challenges. The training program covers a range of essential areas, including epidemiology, biostatistics, health policy, and health promotion. Public engagement and participation are crucial factors for the triumph of public health systems. Public health initiatives require collaboration with communities, stakeholders, and various sectors to enhance health literacy, encourage health promotion and disease prevention, and incorporate the population’s needs and perspectives into public health policies and programs. Investing in and strengthening public health systems demands a collaborative and multifaceted approach that tackles the social, economic, and political determinants of health. It also highlights the significance of prevention, early detection, and swift response to emerging health threats.
Ensuring adequate funding is a crucial factor in strengthening public health systems. Adequate funding for public health is crucial in order to provide the necessary infrastructure, workforce, and programs required to fulfill the essential functions of public health. Achieving adequate funding can be made possible through a combination of government funding, public-private partnerships, and international aid, according to experts. Improving public health surveillance systems and data collection and analysis is crucial for identifying health trends and emerging health threats. This enables informed decisions on resource allocation and program development, which are essential for enhancing public health.
Damian Sendler: Establishing public trust in public health systems is crucial, and can be attained by means of transparent communication. In order to ensure effective communication, it is crucial to provide the public with precise and prompt information regarding health risks and recommended measures, while also addressing any concerns or misinformation that may arise. Transparency is a crucial aspect of public health policies and decision-making processes. It entails being accountable and responsive to the public, relying on sound evidence and data, and involving the public in decision-making. The establishment of public trust is crucial for public health systems to effectively involve the public in health promotion and disease prevention initiatives, as well as garner backing for policies and programs that enhance the health of the population.
Public health and healthcare systems have formed successful partnerships resulting in positive health outcomes. A noteworthy collaboration has been established between the Maryland Department of Health and Mental Hygiene and the Johns Hopkins University School of Medicine. In a collaborative effort, a team of public health and healthcare experts devised the “Maryland Hypertension Control Program” with the goal of enhancing hypertension control in the state of Maryland. The initiative was executed through a collaborative strategy that encompassed engaging with the community, educating healthcare providers, and conducting thorough data analysis and assessment. Over the course of two years, a program implemented in Maryland has resulted in a 7.6% increase in hypertension control rates among residents.
The South Carolina Department of Health and Environmental Control has partnered with the Medical University of South Carolina, as another example. The “Healthy South Carolina Initiative” was developed by a team with the goal of enhancing the well-being of South Carolina residents through prioritizing prevention and bolstering public health infrastructure. As part of the initiative, a thorough evaluation of the public health infrastructure in the state was conducted. This was followed by the creation of a health improvement plan that covers the entire state. The plan was then put into action through the use of evidence-based interventions that target the most pressing health concerns. The initiative has yielded noteworthy advancements in various health outcomes, such as a decline in infant mortality rates and a rise in immunization rates.
The Wisconsin Department of Health Services has formed a partnership with the University of Wisconsin-Madison School of Medicine and Public Health, marking a significant collaboration in the healthcare industry. In a collaborative effort, a team of experts created the “Wisconsin Tobacco Prevention and Control Program.” The program’s primary objective was to decrease tobacco usage in Wisconsin by implementing a holistic approach that involved educating the public, training providers, and implementing policy and systems change. The program has successfully brought about a noteworthy decrease in tobacco consumption rates among the residents of Wisconsin, with a significant impact on the younger population.
The potential for partnerships between public health and healthcare systems to achieve significant improvements in population health outcomes is demonstrated by these examples. Through the strategic utilization of the unique capabilities of each system, partnerships have the potential to enhance coordination and collaboration, minimize redundancy, and amplify the effectiveness of public health interventions. Collaboration between public health and healthcare systems is a crucial element in the pursuit of enhancing population health outcomes and curbing healthcare expenses.
Incorporating public health considerations into policy decisions that fall outside the realm of public health necessitates a collaborative and interdisciplinary approach that entails involving stakeholders, forging partnerships, and utilizing evidence-based tactics. Promoting cross-sectoral collaborations between public health and other sectors, such as education, housing, transportation, and the environment, is a potential solution to achieve this goal. To address shared health goals and priorities, experts from different sectors can come together through the creation of interagency working groups, task forces, or committees.
Damian Sendler: One effective approach is to collaborate with policymakers and decision-makers across various sectors to advance the cause of health equity and address the social determinants of health .It is important to emphasize the significance of evidence-based data and research that establish the correlation between social determinants and health outcomes. It is also crucial to highlight the economic and social advantages of investing in population health. Public health experts have the opportunity to interact with policymakers and decision-makers through various channels, including formal and informal means such as policy briefs, meetings, conferences, and other communication strategies.
Public health experts have the opportunity to work alongside media outlets and other communication platforms to enhance public awareness and education regarding health concerns and policy priorities. As part of their role, health professionals may be tasked with communicating information about potential health hazards, advocating for improved health literacy, and fostering discussions with the community about health equity and the social factors that impact health outcomes.
Public health professionals have the ability to engage in advocacy efforts aimed at promoting policies and programs that support population health and address social determinants of health. Collaborating with community-based organizations, advocacy groups, and other stakeholders is a crucial aspect of promoting policy change and influencing the political and economic systems that affect population health.
The integration of healthcare and public health systems presents a range of potential benefits, such as the improvement of health outcomes, reduction of healthcare expenses, and enhancement of service delivery efficiency and effectiveness. Integration has the potential to promote population health by aligning governance, finance, and service delivery. This approach can lead to the achievement of incentives.
Improving health outcomes through the promotion of prevention and early detection of disease, reducing health disparities, and addressing social determinants of health is a potential incentive for integration. The integration of public health and healthcare systems can effectively address health inequities and enhance access to preventive services. This approach capitalizes on the strengths of both systems to achieve these objectives.
Improving the efficiency and effectiveness of service delivery can lead to a reduction in healthcare costs, providing yet another incentive for pursuing this approach. Integrating healthcare and public health systems can lead to a reduction in duplicated efforts and a more efficient allocation of resources, ultimately resulting in improved health outcomes for the population. By prioritizing prevention and early intervention, healthcare expenses can be curbed by sidestepping expensive treatments and hospital stays.
Damian Jacob Sendler: In order to facilitate integration, a number of strategies can be put in place to ensure that governance, finance, and service delivery are all working in tandem. A recommended approach is to implement shared governance frameworks that encourage cooperation and coordination between public health and healthcare systems. To address common health goals and priorities, stakeholders from both systems can collaborate by establishing joint committees, task forces, or councils. Effective integration relies on critical components such as information sharing, decision-making, and accountability, which can be facilitated by shared governance structures.
One potential strategy is to realign financing mechanisms to facilitate the integration process. Experts suggest that payment models should be designed to encourage prevention, early intervention, and population health management. Payment models that incentivize healthcare providers to attain certain health outcomes or decrease healthcare expenses can foster cooperation between public health and healthcare systems in pursuit of these objectives. Moreover, the establishment of funding streams that endorse collaborative programs and initiatives can foster integration by furnishing the necessary resources to sustain mutual objectives.
In order to improve service delivery, it is crucial to establish integrated care models that facilitate seamless collaboration between public health and healthcare systems, thereby promoting continuity of care.

Integrating service delivery can enhance the quality and efficiency of care, ultimately resulting in improved health outcomes for the population.
Moving forward, it is imperative that research delves into various crucial domains to enhance our comprehension of public health systems and facilitate endeavors to fortify and amalgamate these systems. The development and testing of comprehensive frameworks for public health systems is an area of research that aims to provide guidance for the design, delivery, and evaluation of public health services. Public health systems must be defined clearly in frameworks, which should also outline the essential functions and roles of public health. Additionally, the governance, finance, and delivery mechanisms that support public health systems must be included in these frameworks.
The evaluation of public health interventions on population health outcomes and healthcare costs is another area of research that has gained significant attention. It is important to note that the assessment of prevention and early intervention strategies, as well as the understanding of social determinants of health, are crucial factors in determining health outcomes. Additionally, evaluating the cost-effectiveness of public health interventions is a key aspect of ensuring the most efficient use of resources. Efforts should be made to prioritize research that delves into successful collaboration models between public health and healthcare systems. It is crucial to identify the factors that facilitate or hinder integration.
In addition, it is imperative for upcoming studies to prioritize the establishment of a solid foundation of evidence for the development of the public health workforce. This includes the crucial task of pinpointing the fundamental competencies, skills, and training required for professionals in this field. The efforts to enhance public health systems involve the creation of impactful training and education initiatives, the encouragement of professional growth and leadership, and the recognition of workforce requirements in various settings.
Damian Jacob Sendler: Research must prioritize tackling the wider social, economic, and political factors that influence the health outcomes of populations. Public health initiatives must take into account the influence of policies and programs beyond the health sector on health outcomes. Additionally, promoting health equity and finding successful methods for involving communities and stakeholders are crucial components of these initiatives.
Damian Sendler: Future research should prioritize the advancement of our comprehension of public health systems, as it is an essential aspect of public health practice. This connection to public health underscores the significance of such research. Public health systems are crucial in safeguarding and enhancing the well-being of communities by tackling the social, environmental, and behavioral determinants that influence health results. To improve public health systems, a collaborative and multidisciplinary approach is necessary. This involves filling gaps in knowledge, establishing effective interventions, and finding ways to promote health equity and involve communities in public health initiatives.
