We have just released the Calendar Module for GNU Health.
This module allows appointments to be viewed from any calendar client that supports the CalDAV protocol, like Sunbird/Iceowl, Thunderbird/Icedove, iPhone or Android Clients.
Doctors can use this tool from a desktop computer, notebook or mobile device to manage their appointments. The calendar can also be used by the receptionist to visualize all the doctor’s appointments and make suew that different patients were not being scheduled at the same time.
Thanks to the Tryton team for the CalDAV support.
GNU Health is a Free Health and Hospital Information System.
