High level review of configuration and reform of Public Health systems in selected countries

Abstract Background The impact of the COVID-19 pandemic has prompted governments internationally to consider reform and strengthening of their Public Health systems. To support this work in Ireland, we undertook a review Public Health systems internationally (research question [RQ] 1), and identified lessons learned from the COVID-19 pandemic (RQ2). Methods Data relating to Public Health systems (RQ1), and lessons learned (RQ2) for a select group of 12 countries were identified from organisations’ websites, an electronic database and grey literature search and representatives from key national-level organisations. Data for RQ1 were extracted, mapped to the 12 Essential Public Health functions (EPHFs) at national, regional and local levels, and verified by participating representatives. For RQ2, thematic analysis of semi-structured interviews with participating representatives was undertaken and. Results Typically, across all included countries, there is national strategic oversight of all EPHFs and, for certain functions, there is regional and local level implementation. Lessons learned from the COVID-19 pandemic broadly related to the themes of legislation and decision making; data collection, surveillance, evidence synthesis and collaboration; public health interventions; public participation, public messaging and communication; continuation of healthcare services; and workforce capacity and resilience. Conclusions When structuring Public Health systems, there is a need to identify which functions, and or which elements of a function, should be delivered at a national, regional or local level to ensure a sustainable and comprehensive Public Health system. Appropriate IT infrastructure, strong communication and an established evidence synthesis function are key to timely and informed decision making. Ideally, these functions should be established during periods of relative stability to permit a faster response during a pandemic or emergency situation.


Background:
The COVID-19 pandemic has exposed Public Health system weaknesses due to chronic underinvestment in Public Health. In this context, Essential Public Health Functions (EPHFs) have been revitalized as an integrated, cost effective and sustainable approach to operationalising Public Health. The World Health Organization's recent position paper on building health systems resilience towards universal health coverage and health security recommended investing in EPHFs as a key mean for countries' health systems recovery and transformation during COVID-19 and beyond. There is a need for conceptual and operational clarity of EPHFs to support countries to build back better, fairer and more resilient health systems.

Methods:
A rapid review of peer-reviewed and grey literature regarding the EPHFs was conducted to identify different actors' understandings of EPHFs and key lessons of applying the EPHFs at the global, regional and national levels, in order to identify the added value and key enablers to operationalising EPHFs. A crosswalk analysis of different authoritative lists of EPHFs was conducted to develop a common list of EPHFs as a reference for countries in response to Public Health challenges.

Results:
A consolidated list of 12 EPHFs derived from the crosswalk analysis of different authoritative lists is presented, underpinning the consideration of health systems components and pressing health challenges. Six key enablers are identified from evidence and experience. These enablers are fundamental for countries to build holistic and strong Public Health capacities.

Conclusions:
The EPHFs provide a clear and integrated framing to operationalise Public Health in countries that can be adapted to country contexts to build resilience. Health authorities and other Public Health stakeholders must seize the opportunity brought by COVID-19 recovery to continue advocating for and strengthening Public Health as a priority in health systems' reconstruction and reform.

Weaknesses in Public Health capacities have undermined health system resilience compounding the effects of the pandemic. The Essential Public Health Functions (EPHFs) provide a comprehensive, cost-effective approach to operationalising public health and a means to build health systems resilience. As Ireland looks to recovery, the Department of Health engaged the World Health Organization (WHO) to undertake a mapping of the current state of delivery of EPHFs to identify opportunities for improvement and support wider health system strengthening towards resilience.

Methods:
A strategic review of the delivery of EPHFs in Ireland was conducted with respect to policy, infrastructure, service provision and coordination and integration. Findings were reported in the context of international lessons identified through experience with COVID-19 and major health system challenges within the Irish context.

Results:
There are significant capacities present within the Irish context to support the delivery of the EPHFs though they are limited in strategic cohesion, coordination and implementation. These include a high level of Public Health expertise, an agile and resourceful workforce, a strongly engaged community and significant evidence generation and synthesis capacities. Gaps recognised included ICT infrastructure and capacity, workforce resourcing and support, pandemic planning and public health governance, visibility, legislation, strategy and resourcing. COVID-19 has led to the development and strengthening of mechanisms to leverage a whole-of-government and -society approach to health that should be sustained to tackle ongoing and future stressors.

Conclusions:
The use of the EPHFs within the Irish setting provides a comprehensive approach to strengthening capacities for public health and enhanced population health and wellbeing.
