[Adaptation of the General Data Protection Regulation (GDPR) to a smartphone app for rhinitis and asthma (MASK-air®)]. / Règlement général sur la protection des données pour MASK-air® (application mobile rhinite et asthme).

The General Data Protection Regulation (GDPR) regulates the processing of personal data in the European Union. The legal context is adapted to follow the evolution of technologies and of society. This new European regulation became mandatory, especially for connected devices, on May 25, 2018. An app originally known as "The Allergy Diary" is available for Android phones and iPhones. Its name was recently changed to MASK-air. The downloading and use of this app are free of charge and there are no adverts. It enables users to record their symptoms and their medications to better track the progress of their allergic rhinitis and/or asthma. It has been developed by public (Foundation FMC VIA-LR, University of Montpellier) and private (KYomed INNOV) organizations based in France and therefore falls under French jurisdiction. This article summarizes the five main principles of personal data protection to be respected during the development of the app: purpose, proportionality and relevance, limited retention period, security and confidentiality, as well as the rights of the people who are involved in the management of the personal data (including withdrawal and modification).

Daily allergic multimorbidity in rhinitis using mobile technology: A novel concept of the MASK study.

BACKGROUND: Multimorbidity in allergic airway diseases is well known, but no data exist about the daily dynamics of symptoms and their impact on work. To better understand this, we aimed to assess the presence and control of daily allergic multimorbidity (asthma, conjunctivitis, rhinitis) and its impact on work productivity using a mobile technology, the Allergy Diary. METHODS: We undertook a 1-year prospective observational study in which 4 210 users and 32 585 days were monitored in 19 countries. Five visual analogue scales (VAS) assessed the daily burden of the disease (i.e., global evaluation, nose, eyes, asthma and work). Visual analogue scale levels <20/100 were categorized as "Low" burden and VAS levels ≥50/100 as "High" burden. RESULTS: Visual analogue scales global measured levels assessing the global control of the allergic disease were significantly associated with allergic multimorbidity. Eight hypothesis-driven patterns were defined based on "Low" and "High" VAS levels. There were <0.2% days of Rhinitis Low and Asthma High or Conjunctivitis High patterns. There were 5.9% days with a Rhinitis High-Asthma Low pattern. There were 1.7% days with a Rhinitis High-Asthma High-Conjunctivitis Low pattern. A novel Rhinitis High-Asthma High-Conjunctivitis High pattern was identified in 2.9% days and had the greatest impact on uncontrolled VAS global measured and impaired work productivity. Work productivity was significantly correlated with VAS global measured levels. CONCLUSIONS: In a novel approach examining daily symptoms with mobile technology, we found considerable intra-individual variability of allergic multimorbidity including a previously unrecognized extreme pattern of uncontrolled multimorbidity.
