With the European Respiratory Society (ERS) International Congress 2017 taking place in Milan, Italy on 9-13 September, it’s a good time to focus on some of the important issues facing the asthma community. Asthma is often seen as a low-risk condition that can be “fixed” with an inhaler. In reality, asthma is serious, especially for those with more severe forms of the disease.
Approximately 10% of all asthma patients worldwide – about 31.5 million individuals – have severe asthma, which can require specialist assessment, personalised support and targeted treatments.1,2 And yet, severe asthma is not that well understood outside of the asthma community. It does not generate the headlines that would be expected of a life-threatening disease that affects tens of millions of people every day. Why? Well, part of the reason may lie in how, and how little, severe asthma is talked about.
AstraZeneca recently conducted research on social media across several countries and found that there are few severe asthma conversations happening online. We learned that despite a desire for information, severe asthma conversations are under-represented in the overall asthma conversation online. When conversations do take place, they tend to focus on sharing experiences or seeking solutions, rather than sharing information. And the information that does exist can be inconsistent and difficult to find.
A closer look at the dialogue taking place on platforms like Facebook and Twitter highlights a disconnect between patients and physicians in terms of the language each uses. Patients describe their condition in many varying ways. While some use emotive language to discuss their experience, few identify themselves as having ‘severe asthma’. They may talk powerfully about frequency and severity of their attacks, but use a range of words like “uncontrolled” or “serious” rather than chronic or severe. On the other hand, physicians tend to use specific, medical language so it is easy to see how anyone searching online for information could have difficulty in finding information that feels relevant to them. This variance in vocabulary may be important for us to keep in mind as we work to disseminate news and information around ERS and beyond.
In addition to our research, we hear anecdotal evidence from leading members of the asthma community that people with severe asthma are hungry for more information. Some suggestions on topics of interest include:
- Prevalence: Asthma affects 315 million individuals worldwide, and up to 10% of asthma patients have severe asthma. Severe asthma may be uncontrolled despite high doses of standard-of-care asthma controller medicines and can require the use of chronic oral corticosteroids (OCS).1,2
- Risk: Severe, uncontrolled asthma is debilitating and potentially fatal with patients experiencing frequent exacerbations and significant limitations on lung function and quality of life. 1,3,4
- OCS dependence: Uncontrolled asthma can lead to a dependence on OCS, with systemic steroid exposure potentially leading to serious short- and long-term adverse effects, including weight gain, diabetes, osteoporosis, glaucoma, anxiety, depression, cardiovascular disease and immunosuppression. 5,6,7,8,9
- Physical and socio-economic burden: There is also a significant physical and socio-economic burden of severe asthma with these patients accounting for 50% of asthma-related costs.3,4
- Drivers of disease: Severe asthma is a heterogeneous disease with complex biology and various immunological disease drivers.10 Because these drivers differ among patients and sometimes overlap, targeting specific biologic treatments to patient types has the potential to optimise individual responses to treatment.4,10
We believe facilitating online conversations that connect members of the severe asthma community more easily could be helpful. Equally, there is a real opportunity to improve access to effective information through a standardised terminology and the search terms we use.
AstraZeneca is committed to playing our part in helping improve the digital experience of people with asthma, and ensuring they get access to the information they need. Be sure to follow us on Twitter for updates at @AstraZeneca and @MedImmune to see where this ambition takes us.
We plan to talk with others at #ERSCongress so join the conversation and visit the event page.
