Creeping Crises

Global health challenges and how to handle them
The Future of Life Science at Engelsberg 2024
Creeping crisis

Introduction

Life science is all about revealing the mysteries of life. Life science research aims to understand and explain various processes and phenomena related to living organisms, with the ultimate goal of increasing human knowledge, allowing people and animals to lead healthier lives, and improving the well-being of our planet. To explore how research and breakthroughs within life science affect society, healthcare systems and our lives, Stockholm Science City Foundation together with Nordstjernan hosts an annual symposium The Future of Life Science. At the symposium on May 23-24, 2024, the discussion revolved around global challenges related to health, including climate change, antimicrobial resistance (AMR), and an increase in age-related neurodegenerative diseases. The symposium considered key questions that must be addressed to ensure that unfolding crises don’t become acute disasters: which advances within life science could mitigate these threats; could economic incentives promote more proactive activities and increase the rate of progress; and how should scientists and experts communicate their results more persuasively to engage political leaders and rally public support for change?

This report gives an overview of creeping global crises and their associated challenges. The intention of the report is not to cover all the topics discussed at the symposium, but rather to focus on key topics concerning escalating crises. It highlights the status of specific threats, immediate challenges, and possible strategies to better handle future crises.

The symposium considered key questions that must be addressed to ensure that unfolding crises don’t become acute disasters.

What are creeping crises?

Creeping crises is a relatively new term used to describe threats to widely shared societal values or life-sustaining systems. The development of these threats is gradual and of low intensity but often results in incremental societal disruption, culminating in a sudden major emergency. Creeping crises evolve, often quite slowly, over time and space and are foreshadowed by precursor events. Precursor events may be limited, acute crises such as several local outbreaks of a disease foreshadowing a pandemic. Similarly, increased frequency of thunderstorms or longer dry periods, which are geographically constrained, indicate acute crises we can expect from global warming.

Other examples of creeping crises are antimicrobial resistance (AMR), lifestylerelated diseases, climate change, declining biodiverity, migration streams, fake news and disinformation. Creeping crises are subject to various degrees of political and societal attention. Magnus Ekengren, Professor at Department of Political Science and Law at the Swedish Defence University, delivered a keynote speech at the symposium. Magnus is one of the researchers who coined the term and defined the concept of creeping crises. He contends that these crises are only partially recognized and dealt with by authorities - addressing them properly is challenging and, in most cases, we are unable to use evidence-based measures since knowledge from past crises may not be relevant.

The division between creeping and other types of crises may not be clear. It can be argued, for example, that AMR is an acute rather than a creeping crisis. However, even though 1.3 million people are dying worldwide every year due to AMR, the crisis is far from fully-fledged, and experts agree that measures taken globally and locally to address the issue are insufficient. It is still a crisis that mostly affects certain geographic areas (such as Russia and the African continent), and in other parts of the world the crisis is not yet exerting significant pressure on healthcare systems.

These crises are only partially recognized and dealt with by authorities -addressing them is challenging and we are unable to use evidence-based measures.

Creeping crises that were highlighted during the symposium

Non-healthy habits driving the increase in lifestyle related diseases

It is estimated that around 40% of premature deaths worldwide are attributed to lifestyle factors, including too little physical activity and sleep, poor diet, and alcohol and tobacco use.2 Carl Johan Sundberg, Professor at Department of Physiology and Pharmacology, Karolinska Institutet, explained that although calorie intake is lower today than 70 years ago, physical activity is much lower, leading to excess weight and weak muscles, including weak hearts. This trend is ongoing and in Sweden the proportion of citizens with health-threatening poor fitness has increased from 27% in 1995 to 46% in 2017.3 According to the World Health Organization (WHO) Europe, around 80% of all heart disease, stroke and type 2 diabetes, plus 30% of cancers are avoidable.  

All organs in our body are affected by lifestyle. Carl Johan Sundberg described the positive effects that physical exercise have on the brain, heart, skeletal muscles, endocrine glands and the immune system. Research has shown that even moderate exercise improves physical performance and mobility and contributes to the prevention of most non-communicable diseases. Physical activity also improves mood and cognition. In addition, being physically fit provides better protection when the body is stressed and when responding to acute infections.

In Sweden the healthcare law states that the most severe conditions should be given priority in healthcare. When the resources in the healthcare systems are limited and set by yearly budgets, it isn’t easy to justify a large share of the money being invested in prevention. However, financial models may increase the incentives to work with prevention in healthcare. One example of such models is health impact bonds that was presented by Fredrik Söder, CEO and founder of Health Integrator, during the symposium. In a pilot study done together with Region Stockholm, 925 individuals with pre-diabetes (defined as long-term blood glucose levels, HbA1c, levels of 42-47 mmol/mol, indicating a high risk of developing type 2 diabetes) were identified and included in a program where they were offered different types of support for physical training, diet and other lifestyle-related factors. The cost of 30 million SEK for the support program was financed upfront by private money from an insurance company. Two years after study start, 54% of the participants had lowered their long-term blood glucose level to a value below the risk level, and 85% of the participants felt that the health program had been a contributing factor to improved quality of life. Only 7.5% of participants developed type 2 diabetes over 2 years, compared to an average of 23% if no lifestyle intervention is used. Allocating private money to finance prevention upfront and letting the healthcare systems pay back once the cost savings are evident could solve the problem of limited yearly resources and diminish the risk of push aside other types of healthcare when introducing preventive interventions or new expensive treatments.

To work with preventive activities and promote healthy habits is however not only the responsibility of the healthcare system but also several other stakeholders. To achieve increased physical activity, city planning that supports active transportation such as cycling, walking and public transport is needed. Also, easy access to parks and other recreation areas is important. Schools play a crucial role in promoting physical activity for people from a young age to adolescence. Some experts highlight that ways forward to promote healthy habits are stronger regulations for food producers and a taxation system that favors healthy food. The Swedish Cancer Society together with The Swedish Heart Lung Foundation has started an initiative to encourage politicians to develop a national strategy that promotes healthy lifestyles and sustainable diets for all. Their suggestions include banning advertising of unhealthy foods which targets children; removing VAT on fruit and vegetables; introducing a producer tax on sugar-sweetened beverages; and introducing mandatory labeling of healthy and unhealthy foods. As discussed at the symposium, such changes will certainly require brave politicians and strong opinion leaders.

Antimicrobial resistance (AMR)

Each year 7.7 million deaths, equating to one in eight deaths globally, are caused by bacterial infections and many people around the world still do not have access to basic antimicrobials. However, almost 1.3 million of these deaths are due to AMR, which occurs when bacteria, viruses, fungi, or parasites no longer respond to medicines, resulting in infections that are difficult or impossible to treat. The causes of AMR are severalfold: over-prescribing of antibiotics or patients not taking antibiotics as prescribed, excessive use of antibiotics in farming, poor infection control in hospitals, poor hygiene and sanitation practices; and lack of rapid laboratory tests. There is a pressing need for new, innovative antibacterials, to replace those which are becoming ineffective or less effective due to widespread use. According to WHO, there were 97 antibacterial agents in the clinical pipeline as of 2023. This can be compared to about 10,000 new oncology drugs in clinical trials. Fredrik Almquist, Professor of Organic Chemistry at Umeå University, pointed out that a range of strategies are needed to combat different types of infections and improve the response to AMR. For acute deadly infections, we need to restore susceptibility of microbes to leading antibiotics and use combination therapies with new antibiotics. For non-acute deadly infections, we need to restore and improve the effect of antibiotics, while for non-fatal infections, by default the antibiotics should be replaced by virulence blockers.

Experts in the antibiotics and AMR field agree that too little is being done at all levels to address the AMR crisis. According to Olivier Rubin, Professor at the Department of Social Sciences and Business Globalization and Europeanization, Roskilde University, there are many reasons for this. One is that it is a silent crisis that is difficult to visualize, and the crisis is very fragmented across time, space, different types of diseases and healthcare processes. Another is that there is insufficient backing from the public to implement the measures needed to combat AMR. There are experts and advocates in the field, but more activists are needed.

Since the agreement of a global action plan in 2015, 170 countries have created national AMR action plans.10 However, Olivier claims that we are now losing momentum due to declining political commitment to the processes. This is observed as limited implementation of policies, limited budget allocations in national action plans, and limited commitment to international collaboration. 

Politics is about how power and resources are distributed and allocated in society, and prioritizing the implementation of policies, laws and regulations. In democracies, policies should align with broad public opinions. Olivier highlighted that handling creeping crises, such as AMR, requires both momentum and endurance. The issues need to be kept on the political agenda for many years, and they need to have a public anchoring. He suggested a few points to improve global AMR governance: 

1) to focus more broadly on antimicrobial usage, 2) to agree upon and measure national contributions (compare to the Paris agreement for reduction of CO2-emissions), and 3) to form an international expert organization to follow the development of AMR and suggest mitigation measures.

Most modern cancer therapies rely on effective antibiotics. This suggests that pharmaceutical companies which have developed cancer drugs or have a strong pipeline of drugs in the cancer field, should be interested in the antibiotics field. Some pharmaceutical companies, for example Roche and GSK, do have novel antibiotics in their pipeline, but major investment in the field is still lacking. Most of the pre-clinical and clinical development is instead being carried out by smaller companies.

A key reason why so few new antibiotics are developed that was discussed at the symposium is the weak business case for antibiotics. Once new powerful antibiotics are developed, they should not be used until it is absolutely necessary. With current models of pharmaceutical development and reimbursement of drugs it is difficult to justify investments in the field. As monetary incentives for developing new antibiotics are insufficient, new initiatives are attempting to address this issue. There are ideas on subscription models whereby states pay an annual fee to access new antibiotics once they are needed. However, political enthusiasm for these models has been lukewarm so far. According to Nina Rawal, partner and co-Head of Impact Ventures at Trill Impact, Sweden and the UK are trying to champion subscription models, but a larger group of countries is needed to make such models feasible. At the symposium, it was mentioned that there may also be a challenge with trust between countries. Models to restrict the use of new antibiotics require that no country overuses them once they are developed and released.

Handling creeping crises, such as AMR, requires both momentum and endurance.

Age-related neurodegenerative diseases

With aging populations globally, the incidence of age-related neurodegenerative conditions such as Alzheimer’s disease is increasing. This brings suffering among those affected, both patients and their families, and pressure on society. The global cost of dementia is estimated to be 1.3 trillion USD per year, implying that a cure for dementia would have a value approximately equal to the global GDP. Only a small proportion of the costs associated with dementia today are healthcare costs, and an even smaller part of this is expenditure on drugs. 

Promising new anti-amyloid drugs that slow disease progression are being developed. The first of these drugs (Lecanemab, co-developed by the Swedish company BioArctic) has been approved for use in large parts of the world, including US, Japan and China. Also, simpler and more accurate diagnostics methods consisting of blood tests for Alzheimer’s disease are making it much easier to detect the disease and identify patients who would benefit from drug treatment. The new anti-amyloid drug is based on antibody technology and therefore expensive. In the US the cost of treating one patient is 56,000 USD/year. The drug is not yet approved in EU, but with a similar pricing, if it were to be provided to all eligible patients it would account for 80% of our total national drug budget in Sweden. 

The new drugs are delaying disease progression, but it was suggested that in the future, the greatest impact would probably be achieved by using two or three different drugs in combination. To achieve the full potential of new products, the experts at the symposium thought that healthcare systems first need to set up processes where people at risk are identified, preferably through digital cognitive screening, followed by blood plasma tests. There has to be preventative programs and for those who may benefit from drug treatments, combination therapies would probably be needed. Currently, healthcare systems and budgets are not set up for handling such approaches. Recent research has shown that preventive actions and lifestyle choices may delay the onset of Alzheimer’s disease and slow its progression. In 2020, the Lancet Commission presented a list of twelve risk factors for dementia: diabetes, high blood pressure in midlife, obesity in midlife, physical inactivity, depression, smoking, low education, hearing loss, traumatic brain injury, high alcohol consumption, social isolation, and air pollution.

Only a small proportion of the costs associated with dementia today are healthcare costs.

Francesca Mangialasche, assistant professor at Department of neurobiology, care sciences and society, Karolinska Institutet, described results from clinical studies where the so-called FINGER-model has been applied. This model focuses on five lifestyle interventions: healthy and balanced food, physical exercise, cognitive training, social activities, and management of vascular and metabolic risk factors. Today, 5-, 7- and 11-year follow-ups have been completed and the results show: cognitive benefits, 20% lower risk cardiovascular events, 30% lower risk for functional decline, 60% lower risk of chronic diseases, better health related to quality of life, reduced costs for healthcare and health-economic benefits. Can we also expect that such preventive interventions will save money? Linus Jönsson, professor in health economics at Karolinska Institutet, pointed out that it depends on how the interventions affect the progression of the disease. With compressed morbidity, i.e. when the period of illness and disability preceding death is shortened, expenditure is likely to be lower. On the other hand, if the progression is slower and the time the patient spend in severe states before death is prolonged, the costs may instead increase. Current modelling shows that preventive interventions give some some cost savings, but the biggest benefit would be in Qalys (Quality Adjusted Life Years), i.e. more time would be spent in less severe states of ill health. The experts at the symposium all agreed that when discussing dementia interventions, we need to shift the focus from cost savings to increased health and wellbeing. However, the cost issue is important when deciding upon which interventions to use. Health economics programs must compare outcomes to help decide which healthcare programs should be funded to maximize health gains under given budget constraints.
