Tracking and Promoting the Usage of a COVID-19 Contact Tracing App

Abstract: Digital contact tracing apps have been introduced globally as an instrument to contain the COVID-19 pandemic. Yet, privacy by design impedes both the evaluation of these tools and the deployment of evidence-based interventions to stimulate uptake. We combine an online panel survey with mobile tracking data to measure the actual usage of Germany's official contact tracing app and reveal increased uptake rates among vulnerable groups, but lower rates among those with frequent social contact. Using a randomized i… Show more

“…Most studies of this review converged to the same uptake rate of at least 90% (in the absence of manual contact tracing) to control the epidemic (drop R eff below one). This finding is in agreement with other works that consider a broad uptake in the population as the key for digital contact tracing success ( Munzert, Selb, Gohdes, Stoetzer, & Lowe, 2021 ).…”

“…Nach epidemiologischen Berechnungen bedürfe es jedoch mindestens 56 %, damit die App ihren Sinn erfülle [ 4 ]. Im Besonderen zwei vulnerable Gruppen nutzen die App nicht in erhofftem Maße: Ältere Personen mit Vorerkrankungen, die ein höheres Gesundheitsrisiko zeigen, sind zwar im Durchschnitt etwas geneigter als der Durchschnitt, die App zu installieren [ 18 ]. Dass es dennoch nicht der erhoffte Anteil ist, liegt daran, dass sie seltener ein Smartphone besitzen oder es ihnen an digitalen Kompetenzen fehlt, die App zu installieren [ 4 ].…”

“…Um die Corona-Warn-App insgesamt breiter zu implementieren, und damit ihre Wirksamkeit zu erhöhen, bedarf es also zusätzlicher Maßnahmen: Erstens müssten die technischen Voraussetzungen der App modifiziert, zweitens gezielt vertrauensbildende gesundheitspolitische Diskurse forciert werden. Ein weiterer Ansatz, der jüngst aus Public-Health-Kreisen zu hören ist [ 18 ], wäre die mögliche finanzielle Förderung der Teilnahme an der Intervention: Durch gezielte pekuniäre Anreize könnte, im Besonderen bei jenen Bevölkerungsgruppen die Akzeptanz anregt werden, die sich von dem Motiv des sozialen Engagements nicht angesprochen fühlen.…”

“…Despite strong efforts to deploy these smartphone-based, pairwise encounter-based contact tracing systems, henceforth referred to as SPECTS, there is only limited evidence of their effectiveness [14–16]. This may be due to poor interoperability with manual contact tracing [14] and low adoption rates ( < 25%) in countries that do not mandate their use [17], despite advertising campaigns to promote their adoption [18, 19]. Moreover, a societally sensitive trade-off between utility and privacy has precluded the use of location and associated environmental features (e.g., indoor vs. outdoor).…”
