Introduction:
Public Health England (PHE) was established in 2013 as an executive agency of the Department of Health and Social Care in the United Kingdom. Its mission was clear: to protect and improve the nation's health and well-being, and to reduce health inequalities. Over its eight-year tenure, PHE played a pivotal role in addressing some of the most pressing public health challenges of the 21st century, from chronic disease prevention to the global COVID-19 pandemic.
Though PHE was officially dissolved in 2021, its functions were reorganized into two new entities: the UK Health Security Agency (UKHSA), focused on health protection and emergency response, and the Office for Health Improvement and Disparities (OHID), dedicated to health improvement and tackling health inequalities. However, the legacy of PHE continues to influence public health in the UK.
This article explores the history, impact, and legacy of Public Health England, examining the critical roles it played, the challenges it faced, and how its reorganization into UKHSA and OHID is shaping the future of public health in the UK.
The Formation of Public Health England:
The Need for a Unified Public Health Body:
Before PHE was established, public health in England was managed by multiple organizations, leading to fragmented efforts and a lack of coordination. The Health Protection Agency (HPA), the National Treatment Agency for Substance Misuse (NTA), and other smaller bodies each played individual roles, but the need for a unified approach to public health became increasingly clear.
The creation of PHE was part of the broader reforms introduced by the Health and Social Care Act 2012, which sought to streamline public health responsibilities and place a greater emphasis on prevention. By bringing various public health functions under one umbrella, PHE aimed to enhance the effectiveness and efficiency of public health initiatives, ensuring that resources were used more strategically to address the nation's health challenges.
The Mandate and Structure of PHE:
PHE's mandate was broad, encompassing areas such as health protection, health improvement, and emergency preparedness. The agency was responsible for providing national leadership on public health, supporting local authorities in their public health duties, and delivering specialized public health services.
PHE was structured into several key divisions, each focused on different aspects of public health:
1.Health Protection: This division was responsible for protecting the public from infectious diseases, environmental hazards, and other health threats.
2.Health Improvement: Focused on promoting healthier lifestyles and reducing health inequalities, this division worked on issues such as smoking cessation, obesity, and mental health.
3.Emergency Preparedness, Resilience, and Response (EPRR): This team ensured that the country was prepared for public health emergencies, from pandemics to natural disasters.
4.Knowledge and Intelligence: PHE gathered and analyzed health data to inform public health policy and practice, providing critical insights into the state of the nation's health.
5.Health and Wellbeing: This division focused on the broader determinants of health, such as housing, education, and employment, recognizing that these factors play a crucial role in health outcomes.
Key Achievements of Public Health England:
During its existence, PHE made significant contributions to public health in the UK. Its work spanned a wide range of areas, from communicable disease control to health promotion and policy development.
Tackling Infectious Diseases:
One of PHE's primary responsibilities was protecting the public from infectious diseases. The agency played a key role in managing outbreaks of diseases such as Ebola, Zika, and measles. PHE's work in this area involved surveillance, research, and the development of response strategies to contain and prevent the spread of infectious diseases.
The Fight Against Ebola:
In 2014, the world faced one of the most severe Ebola outbreaks in history, primarily affecting West Africa. PHE was instrumental in the UK's response, providing expert advice on infection control, supporting the deployment of health workers to affected regions, and contributing to the global effort to contain the outbreak. PHE's laboratories were also involved in testing and diagnosing cases, ensuring that the UK was prepared to respond to any potential cases that might arrive on its shores.
Measles and Mumps Control:
PHE also played a critical role in controlling outbreaks of vaccine-preventable diseases such as measles and mumps. The agency worked to increase vaccination coverage, particularly in communities with low uptake of the MMR vaccine. Through public awareness campaigns, targeted interventions, and close collaboration with local health authorities, PHE helped to reduce the incidence of these diseases and protect vulnerable populations.
Health Improvement Initiatives:
PHE was at the forefront of efforts to improve the health of the population through various health promotion initiatives. The agency's work in this area focused on addressing key risk factors for chronic diseases, such as smoking, poor diet, and physical inactivity.
The Fight Against Tobacco:
One of PHE's most notable achievements was its work in tobacco control. Smoking remains one of the leading causes of preventable death in the UK, and reducing smoking rates was a top priority for PHE. The agency supported the implementation of smoke-free legislation, provided resources for smoking cessation services, and ran public health campaigns such as "Stoptober" to encourage smokers to quit. As a result of these efforts, smoking rates in England declined significantly during PHE's tenure.
Tackling Obesity:
Obesity is a major public health challenge in the UK, contributing to a range of chronic diseases, including type 2 diabetes, cardiovascular disease, and certain cancers. PHE launched several initiatives aimed at reducing obesity rates, including the "Change4Life" campaign, which promoted healthy eating and physical activity among children and families. PHE also worked with the food industry to reduce sugar content in food and drink products, as part of the government's broader obesity strategy.
Emergency Preparedness and Response:
PHE's role in emergency preparedness and response was crucial in ensuring that the country was ready to handle public health emergencies. This included planning for and responding to incidents such as natural disasters, chemical spills, and pandemics.
The Novichok Incident:
In 2018, the UK faced a significant public health emergency when a former Russian spy and his daughter were poisoned with a nerve agent, Novichok, in Salisbury. PHE played a central role in the response, providing expert advice on decontamination, risk assessment, and public communication. The agency's swift and coordinated response helped to manage the incident and protect the public from further harm.
COVID-19 Pandemic Response:
Perhaps the most significant test of PHE's capabilities came with the COVID-19 pandemic. As the pandemic unfolded, PHE was responsible for much of the UK's initial response, including testing, contact tracing, and providing public health guidance. The agency's work was critical in the early stages of the pandemic, as it sought to contain the virus and mitigate its impact on public health.
However, the unprecedented scale of the pandemic also exposed some of the limitations and challenges faced by PHE, leading to widespread scrutiny and ultimately contributing to the decision to restructure the agency.
Addressing Health Inequalities:
Reducing health inequalities was a core part of PHE's mission. The agency recognized that health outcomes were often closely linked to social and economic factors, such as income, education, and housing. PHE worked to address these inequalities through targeted interventions and policies aimed at improving the health of disadvantaged communities.
The Marmot Review:
PHE supported the landmark Marmot Review, which highlighted the social determinants of health and called for action to reduce health inequalities in England. The agency worked with local authorities and other partners to implement the review's recommendations, focusing on areas such as early childhood development, education, and employment.
Health Equity Initiatives:
PHE also launched several initiatives aimed at promoting health equity, such as the "Healthy Communities" program, which focused on improving the health of people living in deprived areas. By working closely with local authorities and community organizations, PHE sought to ensure that everyone had the opportunity to live a healthy life, regardless of their background or circumstances.
Challenges Faced by Public Health England:
While PHE made significant contributions to public health, it also faced numerous challenges during its existence. These challenges were often related to the complex and evolving nature of public health, as well as the agency's role within the broader health system.
The Complexity of Public Health:
Public health is inherently complex, involving a wide range of factors that influence health outcomes. PHE had to navigate this complexity while addressing multiple public health issues simultaneously, from infectious disease control to chronic disease prevention and health promotion. Balancing these competing priorities was a constant challenge for the agency.
Financial Constraints:
Like many public sector organizations, PHE operated under significant financial constraints. Budget cuts and limited resources often made it difficult to deliver on its ambitious public health agenda. This was particularly challenging in areas such as health improvement, where sustained investment was needed to achieve long-term impact.
The COVID-19 Pandemic:
The COVID-19 pandemic was perhaps the most significant challenge faced by PHE. The scale and speed of the pandemic overwhelmed public health systems around the world, and PHE was no exception. The agency faced criticism over its handling of testing and contact tracing, as well as its communication with the public and other stakeholders. These challenges ultimately contributed to the decision to restructure PHE, with its functions being divided between UKHSA and OHID.
The Transition to UKHSA and OHID:
The Creation of UKHSA:
The UK Health Security Agency (UKHSA) was established in April 2021, taking over the health protection and emergency response functions of PHE. UKHSA's mandate is to protect the nation from health threats, including infectious diseases, environmental hazards, and bioterrorism. The agency is responsible for surveillance, research, and response activities, ensuring that the UK is prepared for future public health emergencies.
The Role of OHID:
The Office for Health Improvement and Disparities (OHID) was created to focus on health improvement and reducing health inequalities. OHID works closely with local authorities, the NHS, and other partners to deliver programs and policies that promote healthier lifestyles, address the social determinants of health, and reduce disparities in health outcomes. The creation of OHID reflects a renewed emphasis on prevention and health equity, building on the work previously carried out by PHE.
The Legacy of PHE:
While PHE no longer exists as a standalone agency, its legacy continues through the work of UKHSA and OHID. The achievements of PHE in areas such as tobacco control, infectious disease management, and health equity have laid the foundation for ongoing public health efforts in the UK. The lessons learned from PHE's successes and challenges will inform the future of public health, ensuring that the UK is better prepared to address the complex health challenges of the 21st century.
