Asthma impacts over 330 million people worldwide. While severe asthma makes up only 5-10 percent of cases, it is accountable for over half of asthma-related costs globally.[1] It profoundly affects patients’ lives, undermining their physical, mental and economic well-being, and increasing the risk of preventable deaths. Despite its significance, severe asthma is often overshadowed by other health priorities, leading to inadequate resource allocation and substandard care, further straining already pressured health systems.
Severe asthma outcomes, like many other chronic diseases, are deeply entangled with a wide range of environmental and socio-economic factors. Therefore, addressing it is not merely about medical intervention, but about creating and implementing comprehensive, holistic strategies.
The challenges presented by severe asthma are not beyond our capabilities. Around the globe, there is a wide range of best practices, treatments, and approaches to asthma management. Yet, the path to transformation demands a unified commitment from a broad set of stakeholders, from policymakers to medical professionals, industry, patients and beyond. While the blueprint for a future unburdened by severe asthma exists, it is up to decision-makers to realize it together.
While the blueprint for a future unburdened by severe asthma exists, it is up to decision-makers to realize it together.
And the good news is that progress is already underway. Since autumn 2022, we have collaborated as an international expert group to support the development of the Copenhagen Institute for Futures Studies’ (CIFS) Severe Asthma Index. This tool assesses how 29 OECD countries manage severe asthma across various indicators, such as national strategies, treatment access, hospitalizations, societal costs and air quality, among others.
While the Severe Asthma Index is an important stride in tackling severe asthma, the true test lies in how its insights are applied in practice. Among the many actions needed to be taken to improve severe asthma care, the most pressing concern is policy change.
We have identified three actions, derived from the work we have conducted to date, for policymakers to kickstart strengthening health systems’ approaches to and management of severe asthma:
- Development and implementation of national asthma plans and strategies
The Severe Asthma Index has found that less than half of the countries analyzed have a national strategy for asthma, prevention, and management. There is, therefore, a need to formulate and actively implement dedicated national asthma programs, tailored to the unique challenges of individual health systems. These programs should not only emphasize prevention, early detection and diagnosis but also adapt best practices to specific national and local contexts.
Importantly, plans should be situated in the context of long-term strategies for improving population health outcomes.
“In England, work around respiratory illness is gaining traction,” notes Sir David Behan, chair of Health Education England, NHS, and expert group member. “Part of the initiative being developed [is] to ease pressure on the emergency care pathways and hospitals.”
All approaches should promote awareness on respiratory diseases, support personalized care plans, empower patients and improve training and opportunities for training health care professionals working in respiratory care.
2. Coordination and harmonization of policies and care guidelines
There is a patchwork of country approaches to severe asthma, illustrated by the observation that more than two-thirds of the country guidelines assessed in the Severe Asthma Index do not fully align with the Global Initiative for Asthma’s (GINA) guide for Difficult-to-treat and Severe Asthma in Adolescence And Adult Patients. Policymakers must strive to coordinate their approaches to severe asthma by harmonizing policies and guidelines for asthma care to the greatest possible extent, with the aim of reducing outcome disparities, bolstering equity and promoting health system sustainability.
In doing so, there should be an emphasis on identifying and scaling best practices, promoting cross-border collaboration, and championing holistic solutions informed by the widely-acclaimed Health in All Policies approach.
The Australian National Asthma Council’s Australian Asthma Handbook is a strong example of a best practice in this area that policymakers could draw inspiration from in acting on this point.
3. Supporting improved data collection and the development of a more robust evidence base for severe asthma
Policymakers should incentivize and ultimately mandate improved production, recording and utilization of asthma- and severe asthma-specific data, as well as identifier data such as prescription data, adherence to treatment regimes, lung function analysis and demographic and socioeconomic indicators, following a set of common standards.
Currently, despite the existence of clinical codes for severe asthma, the condition remains significantly underreported in clinical settings due in large part to inconsistent coding practices, leading to an increased probability of patients receiving inadequate care and suboptimal allocation of health system resources. The dearth of severe asthma data and barriers to accessing the few datasets that do exist render it difficult to develop a comprehensive and consistent understanding of the full impact of severe asthma.
National policymakers need to prioritize financial and logistical support for country-level asthma research. Research activities should aim to produce a solid evidence base that will offer a nuanced understanding of each country’s needs, challenges and opportunities regarding asthma care. Support for research activities granted over the long term will enable longitudinal studies so that national trends and progress can be accurately tracked.
Only 3 percent of the European Union’s budget for health [is] spent on lung health, although 13 percent of Europeans have lung disease.
“Only 3 percent of the European Union’s budget for health [is] spent on lung health, although 13 percent of Europeans have lung disease,” says Susanna Palkonen, director of the European Federation of Allergy & Airways Diseases Patients’ Associations (EFA) and expert group member.
The International Severe Asthma Registry (ISAR) initiative provides a strong basis for continued work in this area.
The path ahead requires that these actions evolve in tandem with the latest advancements in respiratory care and approaches to the management and prevention of noncommunicable diseases. This is not simply about updating and developing new policies — it’s about crafting robust and well-rounded solutions that proactively address a health challenge that is both global and local and supporting a much-needed vision for improved respiratory health outcomes.
As we look forward, we cannot just treat asthma. We must transform our approach to ensure that every patient’s right to breathe becomes a global reality.
