Metrics for TEKs Uploaded #333

Closed stephenyates-gc closed 3 years ago

stephenyates-gc commented 3 years ago

Our partners at Health Canada have requested additional metrics from the COVID Alert server.

The outcome will be Google Sheets updated daily with the server metrics data segmented by province.

Context The Heath Canada task force will use the data that we provide as a basis for

Context from HC: Once the new exposure window feature is live, it will enable us to estimate how many users are taking advantage of the feature (and inputting a test date or symptom date), and how many choose to use the original 14 day default. This will let us determine how effective the new feature is at reducing burden on the healthcare system and reducing “overnotifying” where someone is notified even if they were not exposed to someone during the infectious period.

In addition, for users that do input a symptom onset date, it will allow us to calculate the average days between symptom onset/test date and a user uploading their TEKs. According to recent evidence this is likely one of the most important metrics for understanding the healthcare outcomes of the app, as the less time between symptom onset/test date and the uploading of their TEKs (and therefore notifications going out and their contacts beginning to self-isolate) the more effective the app is at breaking the chain of infection (since their contacts are self-isolating earlier). And so we plan to include this metric in our performance measurement plan.

Acceptance Criteria

Data to track We need to track each occurrence of a user uploading TEKs for the first time. Each record should include:
