A Charter to Improve Patient Care in Severe Asthma
Severe asthma is a subtype of asthma that is difficult to treat and control. By conservative estimates, severe asthma affects approximately 5–10% of patients with asthma worldwide. Severe asthma impairs patients’ health-related quality of life, and patients are at risk of life-threatening asthma attacks. Severe asthma also accounts for the majority of health care expenditures associated with asthma. Guidelines recommend that patients with severe asthma be referred to a specialist respiratory team for correct diagnosis and expert management. This is particularly important to ensure that they have access to newly available biologic treatments. However, many patients with severe asthma can suffer multiple asthma attacks and wait several years before they are referred for specialist care. As global patient advocates, we believe it is essential to raise awareness and understanding for patients, caregivers, health care professionals, and the public about the substantial impact of severe asthma and to create opportunities for improving patient care. Patients should be empowered to live a life free of symptoms and the adverse effects of traditional medications (e.g., oral corticosteroids), reducing hospital visits and emergency care, the loss of school and work days, and the constraints placed on their daily lives. Here we provide a Patient Charter for severe asthma, consisting of six core principles, to mobilize national governments, health care providers, payer policymakers, lung health industry partners, and patients/caregivers to address the unmet need and burden in severe asthma and ultimately work together to deliver meaningful improvements in care.

Severe asthma is hard to control and affects 5–10% of patients with asthma . This may be a conservative estimate. For many patients with severe asthma, symptoms do not improve with the usual standard of care [inhaled corticosteroids (ICS)], even when medicines are taken correctly and other potential causes of symptoms have been ruled out . Therefore, traditional treatments are either less effective for these patients or must be taken in extremely high dosages, exposing patients to associated and substantial adverse effects. Patients with severe asthma also have more frequent life-threatening asthma attacks, which can have a devastating impact on people’s lives . The struggle to breathe can be a day-to-day challenge that overshadows much of the sufferer’s daily activities, potentially resulting in hospital admissions, intensive care, and even death [9, 10].
In addition to the burden on the individual with severe asthma, the disease impacts on health systems and society . The relatively small severe asthma patient population drives a significant percentage of health care cost, estimated in some countries to be 50% of all asthma-related costs . In other health systems, the care required to treat a patient with severe asthma can be up to five times more expensive than the care required for mild asthma ($1579 vs. $298 US dollars, respectively) .
Guidelines written by the American Thoracic Society (ATS) and the European Respiratory Society (ERS) in 2014 are recognized as the best clinical guidance for severe asthma diagnosis and treatment . However, understanding of the biology and needs of patients with severe asthma is rapidly evolving, and new treatments (e.g., biologics) are being introduced . Approaches to care must reflect these changes and the increasing treatment options available. In response to these changes, we, as representatives of the academic treating community, patient support groups, and professional organizations, have developed a Patient Charter for the care of patients with severe asthma with six principles for consideration (see Box 1 in Appendix). These principles set out to define what patients should expect for the management of their severe asthma and what should constitute a basic standard of care, in line with the latest science and best practice understanding from existing severe asthma care services.
Principle 1: I Deserve a Timely, Straightforward Referral When My Severe Asthma Cannot Be Managed in Primary Care
Patients who present to their general practitioner with difficult-to-manage asthma should be adequately assessed using a structured methodology, such as the “SIMPLES” approach, before severe asthma is considered and the patient is referred to a severe asthma specialist clinic . The “SIMPLES” approach, aligned with cooperation between primary and specialist care, can avoid inappropriate escalation of treatment, streamline clinical assessment and management, and optimize patient referrals . Patients and health care professionals should also have access to a simple, understandable set of criteria for identifying severe asthma based on best practice guidance, such as the ATS/ERS and Global Initiative for Asthma (GINA) guidelines [2, 8]. In general, patients experiencing any of the following should be referred to an expert respiratory physician: oral corticosteroid (OCS) use for > 3 months, more than two rounds of OCS treatment in the past 12 months, hospitalization for asthma in the past 12 months, or impaired lung function despite optimized standard therapy.
Education within the health care and patient communities on these referral criteria would facilitate rapid referral, and systems already in place in many health authorities could be used to automate this process. Studies have reported that patients under the care of an asthma specialist have a reduced risk of being hospitalized for an asthma attack compared with those being managed by a nonspecialist .
Principle 2: I Deserve a Timely, Formal Diagnosis of My Severe Asthma By an Expert Team
An accurate diagnosis is the foundation of effective asthma care [2, 6]. An initial diagnosis of asthma usually occurs in primary care, based on objective testing over a period of time. However, a formal diagnosis of severe asthma requires a more complex assessment following referral to a respiratory specialist . Part of the reason why a diagnosis of severe asthma is complex is the lack of a clear and consistently used definition of severe asthma. Definitions of severe asthma have historically been based on the degree of symptoms, but newer guidance considers the treatment required to attain control. According to international guidelines, asthma is considered severe if, despite the elimination of modifiable factors (e.g., poor inhaler technique/adherence, persistent environmental exposure to disease triggers), it requires high-dosage ICS plus a second controller with or without oral OCS to prevent it from becoming uncontrolled or if it remains uncontrolled despite this treatment .
It is recommended that a diagnosis of severe asthma should be completed by a specialist multidisciplinary team (MDT) with access to the appropriate resources [6, 7, 17]. However, prior to referral, patients presenting with uncontrolled asthma in primary care initially should be assessed to ensure that their symptoms do not remain uncontrolled because of factors other than severe disease . It should first be determined if patients are taking their prescribed medication properly, with good inhaler technique. The presence of uncontrolled comorbid conditions that may reduce the effectiveness of asthma medications (e.g., chronic sinusitis, obesity, gastroesophageal reflux disease) should also be investigated . Measures to improve the accuracy of diagnosis for patients with mild and moderate asthma and persistent symptoms caused by poor medication adherence or triggers other than asthma would also help to ensure appropriate use of specialist care .
In other conditions, such as rheumatoid arthritis, cardiovascular disease, and cancer, there are clear referral pathways and set waiting time targets to ensure rapid diagnosis [18, 19]. Establishing similar targets and clear referral pathways for patients with asthma would help patients receive an accurate, early diagnosis and appropriate treatment.
Principle 3: I Deserve Support to Understand My Type of Severe Asthma
Summary of recognized asthma subtypes (endotypes and phenotypes) based on disease characteristics, treatment response, and disease mechanisms
Markers associated with the disease
Blood IgE 
Genetic tendency to develop allergies is associated with all asthma types, but prevalence is increased in those with early onset 
Eosinophils (IL-5) 
Blood/sputum eosinophil count is a predictive biomarker for increased severity of asthma attacks 
Targeting eosinophils may improve asthma control 
Aspirin-exacerbated respiratory disease
Eosinophils, also IgE
Often severe and exhibits sinusitis and nasal polyposis
Presents as an NSAID allergy
May be genetic 
Neutrophils in the airways are associated with reduced lung function and thicker airway walls 
Typically experienced by patients treated with corticosteroids, limited management options 
Lack of biomarkers 
Poor response to corticosteroid therapy 
Weight loss may improve symptoms 
Presents intermittently with strenuous exercise
More common in athletes with a genetic tendency to develop allergies 
The published European Charter of Patients’ Rights states, “Each individual has the right to freely choose from among different treatment procedures and providers on the basis of adequate information” . Patients should receive relevant information from his or her health care professional in a simple and clear format to better understand the treatment options available and the consequences of different management approaches. Such provision represents a definite unmet need for patients with severe asthma .
Principle 4: I Deserve Care that Reduces the Impact of Severe Asthma on My Daily Life and Improves My Overall Quality of Care
Severe asthma differs from mild and moderate asthma, in part because the patient experience is much worse. Symptoms can affect relationships, careers, parenting, and social lives, and sometimes patients’ abilities to undertake the most basic daily tasks . Patients with severe asthma also have more frequent life-threatening asthma attacks, resulting in hospital admission and potentially death . Furthermore, the adverse effects associated with treatments to manage and prevent such asthma attacks (including OCS, on which patients can become dependent) can also represent a significant burden for people with severe asthma .
The goal of asthma management is to achieve disease control. The definition of asthma control is based on symptoms, lung function, sleep disturbance, limitations of daily activity, use of rescue medication, and the overall assessment of patients and physicians . Assessment of asthma control is used to inform changes made to a patient’s asthma management plan and for prompt referral to a specialist for diagnosis of severe asthma . The benefits of good asthma control include reduced health care resource utilization, fewer missed work/school days, and a lesser risk of asthma attacks .
There is a need to educate patients living with severe asthma to recognize persistent symptoms and know to seek expert treatment to potentially achieve a better health-related quality of life. Frequent patient education on correct inhaler technique is also important to ensure the optimal effect of currently prescribed medications. There should be shared decision-making between patients and their clinicians to ensure that care focuses on limiting the impact of symptoms and the adverse effects of treatment on physical, mental, and emotional health. Each person will be different, so care should be personalized to address what matters most to each individual .
Principle 5: I Deserve Not to Be Reliant on Oral Corticosteroids
Compared with patients with milder controlled disease, patients with severe asthma also experience adverse effects from treatments that are used to manage asthma attacks (e.g., OCS). If these treatments are used long term, the resulting adverse effects may include weight gain, diabetes, osteoporosis, glaucoma, anxiety, cardiovascular disease, and impaired immunity . These can be debilitating, with a significant impact on both other conditions that patients may have and overall health-related quality of life . Adverse effects also have a significant impact on the utilization of additional health care services [31, 32]. Asthma UK reports that patients “loathe” these treatments and that the substantial adverse effects are a significant reason they do not comply with their prescribed medications, which puts them at risk of experiencing a future asthma attack [9, 14]. Now that new, targeted treatment options based on increased understanding of the biology of the underlying disease are available, there is a growing call for severe asthma care to be less reliant on the long-term use of OCS to prevent asthma attacks .
Principle 6: I Deserve to Access Consistent Quality Care, Regardless of Where I Live or Where I Choose to Access It
Severe asthma requires input from a specialist team to confirm a diagnosis and determine the best treatment/management approach for individual patients [6, 8]. However, management practices and patients’ experiences of asthma care exhibit geographic variation, and there is also inconsistency within countries in how patients are managed . A study in seven European countries reported that management and control of asthma were below the standard defined in the GINA guidelines, with most adults (49.5–73.0%) and many children (38.4–70.6%) only having a follow-up visit for their asthma when they experienced an asthma attack [31, 33]. Furthermore, in our experience, it can take patients an astounding 10–20 years to be referred to a respiratory specialist in many countries.
New care models should be considered for the delivery of severe asthma services to improve efficiency and ensure that patients have access to consistent quality care. Treatment of conditions such as diabetes and stroke has been transformed using networks and technology to deliver efficient but effective specialized care . People with severe asthma should receive a personalized approach throughout their treatment journey based on their own individual needs .
Severe asthma places a significant burden on health systems and the lives of patients. Despite existing treatment guidelines, the management of patients with severe asthma in practice all too often fails to sufficiently achieve outlined goals. There is, therefore, a need to urgently review the current care provided for patients with asthma and raise the expectations regarding their diagnosis and treatment. Improvements in the quality of care for patients with asthma falls behind that achieved for other diseases. For example, a patient experiencing a heart attack would not be released from the hospital after an initial attack had been controlled without a plan for follow up and treatment to prevent future attacks. Yet this is the experience of many patients hospitalized for an asthma attack, even though these patients are very likely to experience another attack that could be potentially fatal.
During the past 20 years, the introduction of biologics for the treatment of rheumatoid arthritis, along with improved care from a MDT, has transformed the experience of patients with this disease. Early diagnosis and effective treatment have resulted in a reduction in the number of surgeries and hospitalizations required for the management of rheumatic disease . Steroid therapy is no longer overused. The same revolution is occurring in the treatment of patients with severe asthma, with new biologic treatments becoming available that have demonstrated effectiveness in reducing future asthma attacks for patients with defined subtypes of severe asthma . However, ensuring that patients with severe asthma who may potentially benefit from these new treatments are identified and seen by specialists is fundamental to achieving these improvements. Early diagnosis is particularly important to facilitate the prescribing of these new biologics or to enable patients to enroll in clinical studies of other novel therapies.
To implement these principles, we recommend the following. Asthma patients should request written asthma treatment action plans from physicians, with specific goals detailed, as a mandatory part of the care they receive. They should also request that both their physicians and pharmacists provide or make available training of inhaler technique to them before they fill new prescriptions. This “double check” can help avoid errors. In addition, patient organizations should reinforce the need for written action plans and frequent checks of inhaler technique. Many patient organizations have programs to detail what should be in a written action plan and why is it useful and often provide instructional recordings demonstrating correct inhaler techniques. Patient organization representatives should screen meeting participants as they demonstrate their inhaler techniques and review written action plans to verify they understand them correctly.
The principles we have set out in the Charter to Improve Patient Care in Severe Asthma demonstrate the core elements of quality care that patients with severe asthma should expect to receive. They are based on the latest understanding of the disease and how care should be structured. These principles should be used to benchmark current service provision. We urge policymakers, those responsible for the delivery of severe asthma care, and advocates for better care to use the principles and action plan we have set out here to build consensus on what severe asthma care should look like in their health system, place people with asthma at the center of care, identify the current gaps and areas for improvement, and implement measures to improve the quality of care and outcomes for people with severe asthma with a view to promoting a life with minimal symptoms.
The Patient Charter was initiated by AstraZeneca to inform a discussion about what quality care should look like in the provision of severe asthma services. These principles were debated and refined during a discussion held on 8 September 2017 in Milan, Italy, organized and funded by AstraZeneca. Twelve academic, patient organization, and professional group experts discussed the value of establishing a Patient Charter as a potential starting point for discussions on how to improve severe asthma care.
