Chapter 1 conceptualizes a health system as a collection of interacting elements that are designed to produce outputs that lead to better population health. A system’s elements both “hang together” as a whole and continually interact and affect each other as they interoperate to produce their final result. Systems thinking is one of the most important disciplines enabling one to understand and characterize systems that display dynamic complexity. Systems thinking in health is a framework for seeing interrelationships and repeated events rather than individual activities, for discerning patterns of change, understanding responses to policies, and for deciphering human behavior within health systems and over time.

Systems Simulation

Most problems arising from the operation of the health system are studied and addressed using conventional reductionist methods, which reduce, isolate, and freeze aspects of the system at a given time. This fails to deal with the dynamic complexity inherent in the health system and which is often the source of the problem. The result is that all too often, well intentioned interventions make the original problem worse by failing to fully understand the complexities involved in the origin of a problem (Sterman, 2000). In this article, we introduce system simulation as a means of exposing the underlying causes and systemic structures of problems within the health care system, as well as providing a tool for assessing the likely impact of new interventions. The following sections will examine the advantages of simulation, areas of application, how simulation experiments can overcome some of the limitations of randomised control trials (RCTs), and various simulation methodologies as well as the challenges of conducting simulation experiments.

IntroductionThe debate over the impact of vertical programmes, including mass vaccination, on health systems is long-standing and often polarised. Studies have assessed the effects of a given vertical health programme on a health system separately from the goals of the vertical programme itself. Further, these health system effects are often categorised as either positive or negative. Yet health systems are in fact complex, dynamic and tightly linked. Relationships between elements of the system determine programme and system-level outcomes over time.MethodsWe constructed a causal loop diagram of the interactions between mass polio vaccination campaigns and government health systems in Ethiopia, India and Nigeria, working inductively from two qualitative datasets. The first dataset was 175 interviews conducted with policymakers, officials and frontline staff in these countries in 2011–2012. The second was 101 interviews conducted with similar groups in 2019, focusing on lessons learnt from polio eradication.ResultsPursuing high coverage in polio campaigns, without considering the dynamic impacts of campaigns on health systems, cost campaign coverage gains over time in weaker health systems with many campaigns. Over time, the systems effects of frequent campaigns, delivered through parallel structures, led to a loss of frontline worker motivation, and an increase in vaccine hesitancy in recipient populations. Co-delivery of interventions helped to mitigate these negative effects. In stronger health systems with fewer campaigns, these issues did not arise.ConclusionIt benefits vertical programmes to reduce the construction of parallel systems and pursue co-delivery of interventions where possible, and to consider the workflow of frontline staff. Ultimately, for health campaign designs to be effective, they must make sense for those delivering and receiving campaign interventions, and must take into account the complex, adaptive nature of the health systems in which they operate.

Effective Coverage

Abstract Background The global health community has recognised the importance of defining and measuring the effective coverage of health interventions and their implementation strength to monitor progress towards global mortality and morbidity targets. Existing health system models and frameworks guide thinking around these measurement areas; however, they fall short of adequately capturing the dynamic and multi-level relationships between different components of the health system. These relationships must be articulated for measurement and managed to effectively deliver health interventions of sufficient quality to achieve health impacts. Save the Children’s Saving Newborn Lives programme and EnCompass LLC, its evaluation partner, developed and applied the Pathway to High Effective Coverage as a health systems thinking framework (hereafter referred to as the Pathway) in its strategic planning, monitoring and evaluation. Methods We used an iterative approach to develop, test and refine thinking around the Pathway. The initial framework was developed based on existing literature, then shared and vetted during consultations with global health thought leaders in maternal and newborn health. Results The Pathway is a robust health systems thinking framework that unpacks system, policy and point of intervention delivery factors, thus encouraging specific actions to address gaps in implementation and facilitate the achievement of high effective coverage. The Pathway includes six main components – (1) national readiness; (2) system structures; (3) management capacity; (4) implementation strength; (5) effective coverage; and (6) impact. Each component is comprised of specific elements reflecting the range of facility-, community- and home-based interventions. We describe applications of the Pathway and results for in-country strategic planning, monitoring of progress and implementation strength, and evaluation. Conclusions The Pathway provides a cohesive health systems thinking framework that facilitates assessment and coordinated action to achieve high coverage and impact. Experiences of its application show its utility in guiding strategic planning and in more comprehensive and effective monitoring and evaluation as well as its potential adaptability for use in other health areas and sectors.

Amenable Mortality

SummaryThere has been growing interest in the comparison of health system performance within and between countries. Yet, identifying practical and understandable ways to make these comparisons remains challenging. Health systems are complex, with multiple functions, so any framework must use a range of indicators to capture their different aspects. A fundamental issue relates to how to attribute population health outcomes to activities in the health system. Amenable mortality has been suggested as one way to address this.

The Impact

Abstract Background Economic sanctions, understood as measures taken by one state or a group of states to coerce another into a desired conduct (eg by restricting trade and financial flows) do not primarily seek to adversely affect the health or health system of the target country's population. Yet, there may be indirect or unintended health and health system consequences that ought to be borne in mind when assessing the full set of effects of sanctions. We take stock of the evidence to date in terms of whether - and if so, how - economic sanctions impact health and health systems in LMICs. Methods We undertook a structured literature review (using MEDLINE and Google Scholar), covering the peer-reviewed and grey literature published from 1970-2019, with a specific focus on quantitative assessments. Results Most studies (23/27) that met our inclusion criteria focus on the relationship between sanctions and health outcomes, ranging from infant or child mortality as the most frequent case over viral hepatitis to diabetes and HIV, among others. Fewer studies (9/27) examined health system related indicators, either as a sole focus or jointly with health outcomes. A minority of studies explicitly addressed some of the methodological challenges, incl. control for relevant confounders and the endogeneity of sanctions. Taking the results at face value, the evidence is almost unanimous in highlighting the adverse health and health system effects of economic sanctions. Conclusions Quantitatively assessing the impact of economic sanctions on health or health systems is a challenging task, not least as it is persistently difficult to disentangle the effect of sanctions from many other, potentially major factors at work that matter for health (as, for instance, war). In addition, in times of severe economic and political crisis (which often coincide with sanctions), the collection of accurate and comprehensive data that could allow appropriate measurement is typically not a priority. Key messages The existing evidence is almost unanimous in highlighting the adverse health and health system effects of economic sanctions. There is preciously little good quality evidence on the health (system) impact of economic sanctions.

Abstract The European Commission's State of Health in the EU (SoHEU) initiative aims to provide factual, comparative data and insights into health and health systems in EU countries. The resulting Country Health Profiles, published every two years (current editions: November 2019) are the joint work of the European Observatory on Health Systems and Policies and the OECD, in cooperation with the European Commission. They are designed to support the efforts of Member States in their evidence-based policy making and to contribute to health care systems' strengthening. In addition to short syntheses of population health status, determinants of health and the organisation of the health system, the Country Profiles provide an assessment of the health system, looking at its effectiveness, accessibility and resilience. The idea of resilient health systems has been gaining traction among policy makers. The framework developed for the Country Profiles template sets out three dimensions and associated policy strategies and indicators as building blocks for assessing resilience. The framework adopts a broader definition of resilience, covering the ability to respond to extreme shocks as well as measures to address more predictable and chronic health system strains, such as population ageing or multimorbidity. However, the current framework predates the onset of the novel coronavirus pandemic as well as new work on resilience being done by the SoHEU project partners. This workshop aims to present resilience-enhancing strategies and challenges to a wide audience and to explore how using the evidence from the Country Profiles can contribute to strengthening health systems and improving their performance. A brief introduction on the SoHEU initiative will be followed by the main presentation on the analytical framework on resilience used for the Country Profiles. Along with country examples, we will present the wider results of an audit of the most common health system resilience strategies and challenges emerging from the 30 Country Profiles in 2019. A roundtable discussion will follow, incorporating audience contributions online. The Panel will discuss the results on resilience actions from the 2019 Country Profiles evidence, including: Why is resilience important as a practical objective and how is it related to health system strengthening and performance? How can countries use their resilience-related findings to steer national reform efforts? In addition, panellists will outline how lessons learned from country responses to the Covid-19 pandemic and new work on resilience by the Observatory (resilience policy briefs), OECD (2020 Health at a Glance) and the EC (Expert Group on Health Systems Performance Assessment (HSPA) Report on Resilience) can feed in and improve the resilience framework that will be used in the 2021 Country Profiles. Key messages Knowing what makes health systems resilient can improve their performance and ability to meet the current and future needs of their populations. The State of Health in the EU country profiles generate EU-wide evidence on the common resilience challenges facing countries’ health systems and the strategies being employed to address them.

Overconsumption of health care is an ever-present and complex problem in health systems. It is especially significant in countries in transition that assign relatively small budgets to health care. In these circumstances, trust in the health system and its institutions is of utmost importance. Many researchers have studied interpersonal trust. Relatively less attention, however, has been paid to public trust in health systems and its impact on overconsumption. Therefore, this paper seeks to identify and examine the link between public trust and the moral hazard experienced by the patient with regard to health care consumption. Moreover, it explores the mediating role of patient satisfaction and patient non-adherence. For these purposes, quantitative research was conducted based on a representative sample of patients in Poland. Interesting findings were made on the issues examined. Patients were shown not to overconsume health care if they trusted the system and were satisfied with their doctor-patient relationship. On the other hand, nonadherence to medical recommendations was shown to increase overuse of medical services. The present study contributes to the existing knowledge by identifying phenomena on the macro (public trust in health care) and micro (patient satisfaction and non-adherence) scales that modify patient behavior with regard to health care consumption. Our results also provide valuable knowledge for health system policymakers. They can be of benefit in developing communication plans at different levels of local government.

Gomez and her colleagues have presented a helpful study of the relationship of the chaplains in her health system to physicians which highlights several barriers to a well-integrated relationship and thus to more optimal patient care. We have seen these same barriers as we have consulted with health systems nationally and have also identified many best practices that mediate or even eliminate many of these barriers. This commentary describes some of what we have seen as chaplain-generated causes of those barriers and effective strategies that have been employed to overcome them. We also provide some resources for chaplains who wish to institute some of these best practices themselves.

Ethical Implications

Abstract Background Artificial intelligence (AI) has been described as the “fourth industrial revolution” with transformative and global implications, including in healthcare, public health, and global health. AI approaches hold promise for improving health systems worldwide, as well as individual and population health outcomes. While AI may have potential for advancing health equity within and between countries, we must consider the ethical implications of its deployment in order to mitigate its potential harms, particularly for the most vulnerable. This scoping review addresses the following question: What ethical issues have been identified in relation to AI in the field of health, including from a global health perspective? Methods Eight electronic databases were searched for peer reviewed and grey literature published before April 2018 using the concepts of health, ethics, and AI, and their related terms. Records were independently screened by two reviewers and were included if they reported on AI in relation to health and ethics and were written in the English language. Data was charted on a piloted data charting form, and a descriptive and thematic analysis was performed. Results Upon reviewing 12,722 articles, 103 met the predetermined inclusion criteria. The literature was primarily focused on the ethics of AI in health care, particularly on carer robots, diagnostics, and precision medicine, but was largely silent on ethics of AI in public and population health. The literature highlighted a number of common ethical concerns related to privacy, trust, accountability and responsibility, and bias. Largely missing from the literature was the ethics of AI in global health, particularly in the context of low- and middle-income countries (LMICs). Conclusions The ethical issues surrounding AI in the field of health are both vast and complex. While AI holds the potential to improve health and health systems, our analysis suggests that its introduction should be approached with cautious optimism. The dearth of literature on the ethics of AI within LMICs, as well as in public health, also points to a critical need for further research into the ethical implications of AI within both global and public health, to ensure that its development and implementation is ethical for everyone, everywhere.
