Evidence and lessons learnt from the use of digital telephone technologies for public health

On January 31, 2023, a virtual event was held to present the findings of the studies carried out within the framework of the project DIAMOND-R: “Digital Applications to Monitor Novel coronavirus Disease and Response in Colombia – syndromic and vaccination surveillance”. This event was organized by Javeriana and Johns Hopkins Universities, together with IMEK Research Center in Marketing & Development. This virtual event included the participation of officials from the health, social, demographic, and information technology sectors working at the national and subnational levels. People who address health issues from research or social programs of civil society also participated.


The DIAMOND-R project consisted of several quantitative and qualitative studies that used digital telephone technologies, especially Recorded Voice Response (RVG), to monitor and promote vaccination against COVID-19 among residents in Colombia. During the event, in addition to sharing evidence from the studies carried out, including the co-design of voice messages led by IMEK, and the learning from the research processes that were developed, training was carried out on the use of RVG for public health. A total of 30 people participated in this virtual event. The research articles generated in this project will be available soon.
