Turning health plan letters into real appointments

Broadcast reached over 1,000 patients due for Healthier SG health plan follow-ups via WhatsApp. Within 24 hours of the first message, 15% had already booked their appointments through the automated flow.

Among seniors aged 65 and above, the effect was even stronger: roughly 1 in 5 booked after just a single message, showing that older adults will act when the call-to-action is timely and low-friction.

Driving uptake of ancillary diabetes services

Broadcast invited diabetic patients for DRP and DFS appointments. In a single automated WhatsApp campaign, more than 27% of patients engaged with the full conversation flow.

Automating smoking assessments at scale

For patients with no documented smoking status, clinics typically rely on opportunistic questioning during visits. Using Broadcast, structured smoking assessment workflows were sent over WhatsApp to patients without prior documentation.

Over 139 campaigns were delivered, and 46% of patients completed the full assessment within the chat. This turned a manual, inconsistent workflow into a fully automated process.

Raising awareness of pneumococcal vaccination

A 21-day WhatsApp campaign nudged Healthier SG enrollees aged 40-64 with chronic or immunocompromising conditions to learn about pneumococcal vaccination.

The campaign included pre-programmed nudges on days 3, 7, and 14, with two behavioural-science-informed variants: a self-check pathway and an infographic-led pathway.
