Allergic Rhinitis

Brief summary

The primary objective consists in the comparison of the combined symptom medication score values between (i) patients randomised to the early warning system personalised forecasting messages, and (ii) patients randomised to generic messages already delivered by MASK-air®. The combined symptom medication score has recently been developed in a data-driven way and validated (https://eaaci.org/images/CSMS.pdf); it assesses allergic rhinitis control taking into account both reported symptoms and medication use. As secondary objectives, visual analogue scales on allergic rhinitis symptoms (VAS global, nasal, eye, asthma), and medication use will also be separately compared.

Detailed description

In patients with allergic rhinitis, forecasting potential exacerbation of symptoms may allow patients to adopt the most adequate preventive measures. In this context, we are developing an early warning system combining atmospheric, pollen, patient symptoms and online activity data. This early warning system will be incorporated in a mobile health app, and aims to provide patients with messages indicating whether exacerbations are expected in the subsequent five days. To test the effectiveness of the early warning system in avoiding a worsening of patients' symptoms, undertaking a randomised controlled trial is warranted, particularly comparing personalised forecasting messages versus generic messages. The clinical study will assess an early warning system, which will be developed through the CATALYSE project. This early warning system will be incorporated in MASK-air®, a mobile health app implemented in 19 European countries, and which allows for patients to register their daily allergic rhinitis symptoms(rhinitis, conjunctivitis and asthma) and medication. The early warning system will be based on: patients' symptom information (as registered in MASK-air®); and atmospheric and pollen forecasts provided by SILAM model and Copernicus systems (which are able to provide forecasts for six main allergic pollen types in Europe, and is able to assimilate new observations registered with an hourly time resolution).
