Architecture

Intelehealth Android application runs on low bandwidth mobile data connection so it can operate in the remotest of settings. The mobile app uses complex data-gathering flowcharts, called “mind maps” which together form an assisted history-taking system, HxGuide. Using HxGuide, CHWs gather comprehensive clinical history and conduct clinically relevant physical exams. The app independently guides the CHW through a series of questions and exams based on the patient’s presenting symptoms and medical history. The CHW uploads the gathered clinical data to a cloud server which houses the patient’s Electronic Health Record (EHR). The remote doctor reviews uploaded data through a web portal and can arrive at a management plan such as offering advice, a prescription, or making a referral. The cloud server consists of an EHR server, called OpenMRS which stores patient data and manages the business logic and a Parse server that hosts the images, while a separate Parse server hosts the HxGuide mind maps.
