Context

South Korea's Clova CareCall is a large-language-model-powered conversational AI that places regular phone check-ins with older adults living alone, deployed since 2021 through partnerships with roughly 150 municipal welfare institutions including Seoul, Busan and Gyeonggi Province.

Results

A comparative analysis of municipal data found regions using CareCall had a 44.2% reduction in solitary deaths and a 9.2% decrease in emergency-room visits versus regions without it, plus roughly KRW 34 billion in estimated social value; a separate study of 80 individuals with dementia over 31 weeks (no control group) found median depression scores (GDS) fell from 8.5 to 6.0 and memory scores rose from 3.0 to 4.0.
