Geneva University Hospitals
In a Nutshell

Covid-19 Symptom Monitoring

The University Hospitals of Geneva and Basel started a trial on Covid-19 prophylaxis. To monitor participants during the duration of the study, Visible Solutions AG developed a platform to monitor participants during the duration of the study.

Every day, participants receive a text message or email containing a personalized link to a questionnaire about Covid-19 symptoms, side effects and adherence. The study team takes action on individual reports.

No App required

The personalized online-questionnaires can be opened from a daily SMS or email.

Multi-site capability

Study teams in Geneva and Basel can enroll patients over the same platform.

Red flag alerts

Upon reporting specified symptoms, the  study team is informed proactively.

Follow-up lists

A list displays all symptomatic patients, and patients with side-effects.


If a questionnaire remains unanswered, a reminder is automatically sent.

Anonymized participants

All patients are anonymized, no names are stored.

Study Team Backend

Study team access

The backend collects all reports and provides filters for symptoms and side effects. Manual data entry for missed reports is possible to study administrators.
