How the Health Systems Trust used WhatsApp to improve their adherence programme

The Health Systems Trust has funded healthcare projects in South Africa for over 30 years. Looking to improve the effeciency of their CCMDD programme, they understood that the humans they assist are predominantly using mobile devices.

Apex was the natural choice to power the official HST GCGC WhatsApp chatbot, having already executed USSD solutions for HST.

Since the inception of the WhatsApp chatbot, HST experienced their highest CCMDD sign-ups in a 12 month period, dramatically increased the efficiency of the CCMDD, and WhatsApp is now HST’s biggest digital engagement channel in company history.
