The right ambulance, decided instantly

In emergency medical response, how to efficiently deploy limited personnel and vehicles had become a major challenge. There were also cases where response to severely ill patients was delayed, and situations where over-responding to minor cases strained ambulance crew resources.

Challenge

In emergency medical response, how to efficiently deploy limited personnel and vehicles had become a major challenge.

There were also cases where response to severely ill patients was delayed, and situations where over-responding to minor cases strained ambulance crew resources.

Approach

Based on patient condition and base location data, a machine learning model using LightGBM predicts severity.

By combining optimization algorithms with mathematical programming techniques, the system also recommends effective ambulance deployment, building a mechanism that makes full use of available resources.

Outcomes

Shortened arrival times for severely ill patients and distributed the burden on ambulance crews through appropriate triage of minor cases.

Contributed to building a structure that makes maximum use of limited medical resources.
