chitSMS: Community Health Information Tracking System Using Short Message Service

摘要

Community Health Information Tracking System using Short Message Service (chitSMS) is an extension of CHITS which is a system that stores health records of patients in the barangay. Another project incorporated a mobile component in CHITS, enabling the health worker to visit the patient, do routine check-ups and medical services, and update CHITS when the health worker returns to the health center. Without a remote connection, however, the health worker has to return frequently to the usually distant health center to update the CHITS database with the data gathered from the field consult. chitSMS addresses this by using SMS as a mode of remote data transfer. It ensures the reliable transmission of the data by implementing a modified selective repeat protocol. Furthermore, it performs the Deflate algorithm for compression of the data being sent to minimize the cost.
