Korea University Guro Hospital

AI reservation callbot and speech-based consultation analysis

Guro Hospital reported a 98% call-answering rate after introducing AI call support

WorkingCompany's own claim

Problem

The hospital's call center missed calls and needed callbacks. Returning patients also needed to manage appointments outside normal consultation hours.

Approach

The hospital began the project with Broad C&S after selection for an AI voucher program in March 2022. Its KUMI callbot handled routine appointment requests from returning patients. A speech-recognition solution converted recorded messages into text for staff follow-up.

Results

98%call-answering rate, up from 88%, per the hospitalCompany's own claim[1]
150monthly callbacks, down from 2,000, per the hospitalCompany's own claim[1]
30%reduction in call duration, per the hospitalCompany's own claim[1]

Takeaway

The results covered the combined callbot and speech-recognition deployment. The hospital did not isolate each component's contribution.
