Background and History
The Buenos Aires city Government is working on an EMR|CIS platform for the 35 public hospitals in the urban area. The first steps involved developing an appointment module based on MS visual basic. Due to expensive licenses, the government decided in 2004 for use open source languages. 2004 paved way for the development of ADT and appointments modules for outpatients. In 2006 and 2007 they added a web based form based on epidemiological data with ICD 10 codification. In 2008, the pharmacy module was added.
