GLIF: Clinical Decision Support System

GLIF is a Clinical Decision Support System (CDSS) designed to assist community health workers with medical decisions. It would function similarly to the SMS question-answering service ChaCha. By capturing data exhaust, it may also help epidemiologists identify and contain outbreaks in the developing world.

In order to circumvent language barriers and illiteracy, GLIF uses a system of pictorial and numeric communication. Basic information about patient and symptoms (“male / age 3 / yes fever / 72 w / yes nailbed pallor / question treat for malaria / question which medication / question what dosage / question how long”) is converted into hexadecimal sequence by a community health worker using a pictographic key, then automatically decoded on the receiving end. The receiver is presented with the question and a list of suggested responses. Suggestions take into consideration such factors as the location of the sender. A response is chosen, sequenced, sent, and again decoded by the community health worker using the pictographic key.
