enGeno: Towards enabling a medical genogram library for supporting home-visit patient diagnosis

A genogram refers to a family tree used for medical purposes. It is a useful diagnosis tool for physicians to understand patients' family information. There are many programs that attempt to support genogram creation, but each has its own limitation. For examples, some programs require users to pay usage fee and to install them in computers in order to view and edit genograms. While free Web-based genogram tools offer more economical alternatives to the formers, their users usually cannot save genograms for later edition. Moreover, it is not possible to integrate and reuse functionalities from these existing programs in users' own systems. Therefore, we propose a JavaScript library, called "enGeno", to address the above issues. From our performance evaluation, the enGeno library can efficiently provide physicians capabilities to store and retrieve information about their patients.
