Abstract
The concept of health system resilience has been challenged by the COVID-19 pandemic. Even well-established health systems, considered resilient, collapsed during the pandemic. To revisit the concept of resilience two years and a half after the initial impact of COVID-19, we conducted a qualitative study with 26 international experts in health systems to explore their views on concepts, stages, analytical frameworks, and implementation from a comparative perspective of high- and low-and-middle-income countries (HICs and LMICs). The interview guide was informed by a comprehensive literature review, and all interviewees had practice and academic expertise in some of the largest health systems in the world. Results show that the pandemic did modify experts' views on various aspects of health system resilience, which we summarize and propose as refinements to the current understanding of health systems resilience.

Introduction
The idea of improving the resilience of health systems has been studied and discussed since the 2000s, although not always using resilience as a concept (Gilson, 2012; Murray and Frenk, 2000; World Health Organization, 2010; World Health Organization, 2000). As external and internal shocks increasingly affected health systems functionality worldwide, the expression “health system resilience” emerged as an adaptable approach to analyzing the impacts of different types of crises, such as economic downturns (Thomas et al., 2013), the Ebola epidemic (Kruk et al., 2015; Ling et al., 2017), influxes of refugees (Alameddine et al., 2019; Ammar et al., 2016), and infectious disease outbreaks (Nuzzo et al., 2019), among others. Only after 2014, the concept of health system resilience gained relevance in reports from the European Union (EU) (European Commission, 2014), Organization for Economic Co-operation and Development (OECD) (OECD. Organisation for Economic Co-operation & Development, 2014), Oxfam (Kamal-Yanni, 2015), and the World Health Organization Regional Office for Europe (WHO/Europe) (WHO Europe, 2017). Analytical frameworks were designed to evaluate health system capacity for responding to public health emergencies, focusing predominantly on high- and low-and-middle-income countries (HICs and LMICs) (Irene Papanicolas et al., 2022; Thomas et al., 2020; WHO Europe, 2017).
With advances in the concept, stages, and dimensions of health system resilience, initiatives to monitor and evaluate proposed analytical frameworks emerged, such as the Global Health Security Index (Bell and Nuzzo, 2021) and the European Observatory on Health Systems and Policies reports (Sagan et al., 2021; Thomas et al., 2020; WHO Europe, 2021). Despite the efforts to establish the characteristics of the most resilient countries and to propose rankings among them, the COVID-19 pandemic (World Health Organization, 2020) has challenged the concept of resilience and brought new issues into the discussion (Forman et al., 2022). For example, the Global Health Security Index (Bell and Nuzzo, 2021) ranked the United States and the United Kingdom as the 1st and 7th countries, respectively, best prepared to respond to a new health emergency. Yet, based on the number of COVID-19 deaths per million people (University of Oxford, 2022), these countries have shown worse results than the world average. Countries with well-structured and integrated health systems, such as some Western European countries, were severely hit by the pandemic (Aarestrup et al., 2021; Burau et al., 2022). Also, qualitative and quantitative metrics in the health system resilience literature still face difficulties, in particular, related to qualitative indicators in the governance dimension and to quantitative indicators aimed at measuring changes associated with shocks (Fleming et al., 2022).
The COVID-19 pandemic is the most severe global health emergency since the 1918–19 influenza. It brought unprecedented challenges that tested health systems' capacity to cope and respond to shocks, ultimately revealing that the world was not prepared to respond to such emergencies. This raises the question of whether there is anything new we should look at after two and a half years on from the initial impact of the COVID-19 pandemic to update knowledge on the health system resilience concept, stages, analytical framework, and implementation mechanisms.
To address this question, we performed a two-step qualitative analysis. First, we conducted a comprehensive literature review to identify critical themes on health system resilience. Second, we conducted semi-structured interviews with 26 world-renowned experts in health systems, and the interview guide was informed by the themes identified in the first step. Semi-structured interviews aimed at collecting informed opinions on the gaps and needs for revision of the current understanding of health system resilience, considering the challenges imposed by the COVID-19 pandemic.
Methods
A deductive qualitative approach comprised a) a comprehensive literature review on health system resilience, b) semi-structured interviews with world-renowned health system experts (with an interview guide informed by the literature review), and c) content analysis of the interviews. The deductive qualitative approach was chosen to link the categories created by the scoping review with the knowledge collected from the experts in the interviews (Saulnier et al., 2022).
Literature review
We used a scoping review approach to collect and categorize scientific papers and reports about health system resilience in the world. In this sense, our literature review is qualitative in nature by extracting information on health system resilience concepts, stages, dimensions, or implementation, and not by measuring quantitatively the studies through bibliometric analysis or meta-analysis.
The first search was conducted in September 2020, and updated every 3 months until September 2022 (Fig. 1 ).

Description: the scoping review flow chart demonstrates the applied steps to collect and select the scientific papers and technical reports used in the paper.
For scientific papers, we searched the strings “health system” and “resilience” in the Web of Science, PubMed, and Scopus databases with no time filter. An initial screen was done based on the title, keywords, and abstract. For reports, we searched the strings “health system” and “resilience” and “report” in the google academic platform. Results were filtered by the publishing organization (e.g., World Health Organization and its regional offices, European Commission, OECD), and initially screened based on the title and abstract.
We used the Mendeley reference manager software to organize and detect duplicated studies. We used the PRISMA flow diagram to guide the steps and eligibility of the collected scientific papers and reports following Page et al. (2021). The authors screened the titles, abstracts, and summary executive and excluded those with clearly no relevant information to the health system resilience discussion. In sequence, the authors reviewed the full scientific papers and reports and elected those to be included in the final sample, based on their contribution to the health system resilience concept, stages, dimensions, or implementation.
We extracted from the included studies the general characteristics (title, authors, abstract, year, journal/organization) and the full texts. The full texts were analyzed through content analysis, and we created categories according to the health system resilience concept, stages, dimensions, or implementation to organize the existing topics.
Semi-structured interviews
We sought experts with solid knowledge of health systems, both in the practice and academic fields. The selection criteria were two-fold: i) current or previous work as a health system practitioner – e.g., worked for a government, served as a health advisor for a government, or worked in a WHO/UNICEF unit of a country, and/or ii) an academic with expertise and active research in health systems – e.g., professors, senior lecturers, or WHO/UNICEF advisors with published reports and/or relevant scientific papers.
Deductive content analysis of the semi-structured interview transcripts was done using QSR NVivo v.12. Categories and subcategories were discussed in light of the literature review and classified as novel contributions if not present in the available literature. In this sense, we deducted the content of the experts’ interviews through the categories and subcategories generated by the scoping review (Naylor et al., 2018).

Semi-structured interviews
We interviewed 26 world-renowned health system experts, with experience in 27 countries across all continents, except Antarctica (Fig. 2 ), between November 23, 2021, and March 1st, 2022. The final sample included health systems’ perspectives from 7 of the 10 most populous countries in the world (China, India, the United States, Brazil, Nigeria, Russia, and Mexico) (World Bank, 2021), and some of the leading universities and organizations in health system research (Table 2 ). The interviews had an average duration of 28 min, ranging from 14 to 59 min (Appendix 1). Although the length of the interviews varied across interviewees, we did not observe any differences in the depth of information collected by interview length.”

Health system resilience - concept
The scoping review indicated an evolution in the concept of health system resilience. Initially, there was a focus on the capacity of the system to absorb shocks and maintain its functions and identity (Thomas et al., 2013). This initial concept was revised to consider (i) preparedness and learning, including the analysis of the role of actors, such as institutions and the population (Chua et al., 2020; Kruk et al., 2015; Ling et al., 2017; Nuzzo et al., 2019); (ii) recognizing that shocks could be internal or external to the system (Ammar et al., 2016; Ozawa et al., 2016; Van de Pas et al., 2017); (iii) management as a sequence of actions that imply absorbing, adapting, and transforming; and (iv) different shock types, such as epidemics, pandemics, or natural disasters (Blanchet et al., 2017; Khan et al., 2018; Nzinga et al., 2021; Saulnier et al., 2021). Lastly, based on previous studies, a synthetic version was created considering the ability of preparedness, management (including absorb, adapt, and transform), and learning when facing a shock (Biddle et al., 2020; Fridell et al., 2020; Thomas et al., 2020).
Analysis of the semi-structured interviews showed that experts interviewed demonstrated knowledge of the health system resilience concept and its evolution, mainly with the emphasis on the ability or capacity to keep the health system operating and learning about shocks (Haldane et al., 2021; Kruk et al., 2015; Thomas et al., 2013, 2020). According to the interviews, however, that ability or capacity could influence or be influenced by community participation and context understanding. This is a novel concept improvement, not found in the scoping review. As one interviewee said:
“… healthcare systems don’t happen to people, they happen with people. So at the same time understand their expectations and how they react when a crisis happens … and then we switch back to the technical part because it is a lot easier. And then we follow to political and then legal ….”
When inquired about possible changes in the health system resilience concept considering COVID-19, experts suggested that the concept of health system resilience has been tested, challenged, and therefore changed.
“It showed a certain amount of flexibility, and the things that people might have taken years to implement in a hospital were implemented overnight. A pivot to telehealth, for example, things, you know, people have been talking about that, but well, it just had to happen.”
The changes proposed are a) resilience needs to have a strong element of context in your concept; b) health system resilience should go beyond the health care boundaries, emphasizing the need for financial, political, and social support; c) health care supply chain gained importance in the health system resilience discussion, with influence on public policies; d) health system resilience should include new technologies and instruments to strength resilient health system, as artificial intelligence and telemedicine; and e) surveillance, governance instruments, and social measures should gain more relevance in the health system resilience debate.
Health system resilience - stages
Based on the scoping review, health system resilience includes four stages (Burke et al., 2021; Khan et al., 2018; Thomas et al., 2020). The first, preparedness, represents the health system's readiness to respond before the shock event (Aarestrup et al., 2021; el Bcheraoui et al., 2020). The second, onset and alert, aims to understand the shock and establish timelines of action (Thomas et al., 2020). The third, shock impact and management, refers to the health system in action during the shock, with some adaptations and transformations to keep the health system operating (Burke et al., 2021; Khan et al., 2018). Finally, recovery and learning is the process of rethinking the health system and how it could be made more resilient (Sagan et al., 2021; Sheikh and Abimbola S. editor, 2021).
Experts interviewed proposed some changes to this framework. The first relevant change is to consider the four stages as a complex adaptive system with a continuing process of multiple interconnected and interdependent interactions among stages, thus building upon the framework developed by Thomas et al. (2020).
“They're all connected in true life. They overlap quite a lot. We are dealing with a complex adaptive system. I mean, unfortunately, when we try and classify stages, which is convenient, because when we are trying to under each heading consider, what are the actions that are required, what are the consequences of an action? And what are the consequences of inaction? It is convenient to divide into stages, but quite often, we find that in a complex adaptive system, there is an iteration of very many factors and alteration of very many factors as they come into play. And therefore, I don't think we can always say that these are sequential”.
At the core of that adaptive system should be the decision-making process and management capacity, influencing all the stages of action. Interviewees discussed the importance of the decision-making process through management. Therefore, the decision-makers – e.g., health system managers, front-line health professionals, among others – are the core of the adaptive system, and the management capacity connects them with all the other stages. Also, the resilience adaptive system is part of the health system, which influences and is influenced by the context.
Health system resilience - dimensions
Based on the scoping review, dimensions to be considered in the assessment of health system resilience have their roots in analytical frameworks to evaluate health system performance, initially proposed by the WHO in 2000 (Murray and Frenk, 2000). Over time, many changes were proposed to those frameworks, with dimensions (or building blocks) to analyze health systems including financing, service delivery, health workforce, health information systems, medicines/vaccines/technology (Olu, 2017), leadership and governance (World Health Organization, 2010), and community engagement (Barasa et al., 2018; Khan et al., 2018). These health systems dimensions contributed to creating a version to evaluate health systems resilience, proposed in 2020 and continued to be refined until 2022 (Irene Papanicolas et al., 2022; Thomas et al., 2020). Dimensions considered include governance, financing, resources, services delivery, political environment and community, legal foundation, risk communication, and containment measures (Haldane et al., 2021; Mustafa et al., 2021).
We cited in the interviews the building blocks framework (World Health Organization, 2010) and two health system resilience frameworks (Haldane et al., 2021; Thomas et al., 2020) to contextualize the discussion. Experts interviewed suggested several changes to health system resilience dimensions, such as (i) the framework needs to act as an integrated system, not fragmented by building blocks due to the relationship among dimensions; (ii) the center level is the decision-makers dimension, connected with the health system resilience dimensions through technology and information; (iii) technology and information gain relevance with the role of interfacing with all the health system resilience dimensions improving their performance; (iv) regulation is part of governance and leadership in the dimension; (v) a fourth level is proposed to connect the health system resilience dimensions with the context, through communication and social participation; and (vi) the inclusion of medical and public health approaches in the services provision dimension.
“Only things missing there. I thought was the government's response. The health information systems. Some of these elements were missing.”
“We need to use a little bit of bottom-up, which means to know how the organizations and institutions responded and adjusted (…). But also, it needs to understand the top down, and how the system works from top to down, because we are talking about mobilization, information systems, (…).”
Health system resilience in a comparative perspective
Based on experts’ interviews, there should be no differences in how the governance, leadership, and regulation dimensions of resilience are implemented in health systems in HICs or LMICs. Governance and regulation mechanisms, such as decision-making, evidence-based, and accountability, are more frequently found in HICs. Resources dimensions (human, physical and structural) in HICs are usually greater than in LMICs due to the greater financial capacity.
As for the medicines dimension, the COVID-19 pandemic showed the importance of logistics and healthcare supply chain, particularly for the delivery of vaccines. Here, HICs have been learning and adapting the health system services provision dimension faster than LMICs.
Regarding technology and information, one of the different elements could be the instruments and tools to plan, monitor, and evaluate these targets, such as information and communications technologies. HICs usually have a better instrumental capacity to follow and incorporate targets.
“(…) the essential difference here between developed and developing countries is probably in the available resources. (…) everything that is a decision-making process, informatics and mobilization infrastructure, and resources that could be mobilized probably, I would say, there you would have some difference to developing countries.”
In contrast, communication and social participation are important instruments to influence the governance, leadership, and regulation dimension, and do not depend on being HIC or LMIC. Also, before incorporating resilience into countries’ health systems, it is important to comprehend the context. Some context elements include trust in institutions; solidarity; the likelihood of outbreaks (natural disasters, war, or conflict); socioeconomic vulnerability; and whether primary health care works as the health system base. Despite that, social protection mechanisms play an important role to keep the health system resilient.
Health system resilience framework implementation
Resilience framework implementation is a major gap in the literature, based on the scoping review. Experts interviewed discussed implementation considering political, legal, economic, and technical perspectives. From a political perspective, four issues were identified as critical: (i) bring society to the center of the discussion through participatory mechanisms that facilitate understanding of what a resilient health system would mean to them; (ii) adapt the international discussion to national, regional, and local scenarios; (iii) have the government, or a policy champion, supporting implementation in different levels; and (iv) create a transformation process in the health system, with a long- and well-established plan. Legal elements, such as laws, decrees, and ordinances, could influence implementation, as they (a) connect the different subsystems in the healthcare sector (public, private, and supplementary), (b) measure and understand the impact of healthcare judicialization, and (c) have a strong and flexible regulation to quickly support the health system adaptation.
“(…) you're going to have to engage, not just the Ministry of Health, but all the particular economy, finance, the other sectors that have been very clearly impacted by the pandemic and make the strong, make the strong justification, (…). The arguments at the moment will be you, you should be able to make them even recognizing the current situation there at the moment, from the economic perspective on the political economy perspective. Also, (…) strengthening of the health system there from the technical a strategic perspective.”
From an economic perspective, it is essential to establish a fund to support implementation, understand the resource constraints of the healthcare system, and improve resources management capacity in strategic areas. Lastly, regarding technical elements, five actions were highlighted by the experts: (i) create or adapt a national representative survey to increase social participation and bottom-up communication by analyzing people's perception of what a resilient health system is; (ii) establish national, state, regional, and local data analysis capacity; (iii) improve health care data system interoperability between government spheres (e.g., federal, state, regional and local) and country borders, health care subsystems (private x public), and different services delivery subsystems (e.g., PHC and specialized care); (iv) have a high and stable competent team to manage, implement, monitor, and assess the health system resilience framework implementation; and (v) create a benchmarking atmosphere between the health departments in state, regional and local levels.
Discussion
Health system resilience has gained relevance in academic and practical discussions, affecting the decision-making process of many countries worldwide since the beginning of the 21st century. In the last two and a half years, the COVID-19 pandemic challenged the concept of health system resilience. Here, we reviewed the current literature and conducted interviews with experts to discuss the advances in health system resilience.
First, the resilience concept was improved with the addition of one important element: context dependence (Gilson et al., 2020; Sagan et al., 2021). It is important to consider the management and learning capacity with shocks, but also the context in which the shock happens. The capacity or ability to respond must engage the community, with an empathetic approach, and be adapted to local contexts. This understanding provides a refinement to the health system resilience definition as seen in the last studies (Biddle et al., 2020; Fridell et al., 2020; Haldane et al., 2021; Thomas et al., 2020). Specifically, it could be read as the “ability to prepare for, manage (absorb, adapt, and transform) and learn from shocks, based on community participation and context adaptation”. This refinement was influenced by the COVID-19 pandemic, placing more emphasis on non-medical elements, such as health surveillance (Haldane and Morgan, 2021; Legido-Quigley et al., 2020; Sundararaman et al., 2021), health care supply chain (Bhaskar et al., 2020b; Kandel et al., 2020), governance mechanisms to coordinate integrated responses (Haldane et al., 2021; Haldane and Morgan, 2021), and speed in the development and incorporation of new health technologies to support response worldwide (from vaccines to digital health) (Bhaskar et al., 2020a).
Second, we summarized the suggestions regarding the health system resilience stages in Fig. 3 . Decision-making gains a central role in the response to shocks and crises, supported by its management capacity, connected with all the health system resilience stages, and in constant interaction with the health system and the context. Most importantly, the previous four health system resilience stages discussed in the literature (Thomas et al., 2020) should be seen as an adaptive system (Atun et al., 2013; Haldane et al., 2021).
Fig. 3.
Health system resilience adaptive stages.
Description: the scheme illustrates the health system resilience stages, with a complex-based adaptive system and in constant interaction. Decision-making has a central role and is operationalized by the management capacity to connect with the 4 stages, acting in the health system environment and context.
Third, the scoping review and interviews brought advances in the health system resilience dimensions, with a new and adaptable framework. We summarize the findings in Fig. 4 and propose a system-based approach with technology and information systems playing an important role to connect the decision-makers with all the health system resilience dimensions (Yoon et al., 2022). In this refined framework, regulation gains more emphasis on governance and leadership (Bhaskar et al., 2020a; Kandel et al., 2020; Kringos et al., 2020; Sagan et al., 2021), and communication and social participation appear in the fourth level, connecting all other dimensions with the context. Therefore, the proposed framework (Fig. 4) advances in the health system resilience analysis with a system model, based on the importance of the decision-makers and management capacity, powered by technology and information, to improve the third-level dimensions performance. Also, the framework shows the importance of communication and participation to connect the health system's performance with the context.
Fig. 4.
Health system resilience framework.
Description: the figure illustrates an adaptable health system resilience framework. The decision-makers are in the center and connected with the 6 dimensions through technology and information. All the health system resilience dimensions interact with the context using communication and social participation.
In a comparative vision between HICs and LMICs, the main differences to incorporate resilience in health systems are resources (Haldane et al., 2021; Haldane and Morgan, 2021), social protection capacity, logistics and supply chain structure, and information and communication technologies (Bhaskar et al., 2020b; Haldane et al., 2021; Sundararaman et al., 2021). Governance mechanisms depend on the democracy maturity stage and are more frequently found in HICs (Foroughi et al., 2022; Lal et al., 2021; Robert et al., 2022), while communication and social participation, context, and target dimensions play a similar role in all countries. To properly respond to crises, it is necessary to have all parts of the health system resilience framework work together.
Regarding the implementation of the health system resilience framework, it is necessary to understand people's expectations about what a resilient healthcare system to them would be (Haldane et al., 2021; Nimako and Kruk, 2021), adapt the discussion to different government levels (H. C. Karamagi et al., 2022), and have policy support and a strong narrative (Herron et al., 2022). Therefore, organizations and actors must be connected (Kringos et al., 2020; Sundararaman et al., 2021; Williamson et al., 2022), through an improved information system (Chua et al., 2020; Jit et al., 2021; Sagan et al., 2021) and flexible regulation, to better respond to a crisis (Bhaskar et al., 2020a; Kandel et al., 2020). Having a stable team to manage the initiative and create a benchmarking environment between all the actors should be considered (Carroll et al., 2022; Yoon et al., 2022).
Finally, most studies on health systems resilience have focused on the context of HICs with well-established health systems or LICs with very fragile systems. It is essential to expand studies on health system's resilience in the context of MICs with highly fragmented systems in the public and private sectors.
Conclusion
Based on a scoping review and in-depth interviews we propose improvements in the health system resilience discussion. We revisited key aspects of the concept, stages, dimensions/framework, differences across countries, and framework implementation.
This paper contributed new conceptual insights to the health system resilience academic debate as well as to the policy and practical discussion around the topic by i) advancing towards a refinement in the health system resilience 4 adaptive stages model and the health system resilience framework; ii) pointing out differences in the way health systems resilience should be incorporated in HICs and LMICs, iii) identifying the timing and conditions upon which the health system resilience framework should be implemented; and iv) identifying gaps in the understanding of health system resilience in countries with fragile institutions and financial vulnerability.
