Table 1 Summary of key performance indicators and results of the population-based controlled experiment.
KPI | Result |
|---|---|
Adoption | ~33%, potentially larger based on indirect survey data. |
Adherence | high during the whole duration of the experiment. |
Compliance | 64% of those cases that are given a code introduce it in the app. |
Turnaround time | 98% of those index cases that comply introduce the code within 24 h, and on average it takes 2.35 days between a simulated index case introduces a code in the app and the alerted close-contacts follow-up with call centre. |
Follow-up | 10% of notified close-contacts follow-up with a call to the designated point of care (call centre). |
Overall detection | on average and after adequate Bluetooth calibration, the app can trace 6.3 close-contacts per index case. |
Hidden detection | between 23% and 39% (depending on the survey form) of exposed close-contacts are strangers to the index case. |
