Mental health is one of the areas that involves more attention, since the actions taken within the services network cannot be reduced to closed systems without communication with other systems, but with open, heterogeneous and articulated ones. Thus, a search for new possibilities for the realization of continuous and articulated work between different levels of mental health care network is necessary. Given this context, the main objective of this project is to develop and deploy a web based health information system for patient management in order to perform the monitoring of the flow of patients with mental disorders. To this end, the project will include the use of web technologies such as PHP, HTML, JavaScript and CSS, Database Management System MySQL, and Apache web server. A web based system called SISAM 13, that allows appointments, requests for hospitalizations, hospitalizations and the movement of patients in the public mental health network, providing management reports, was created. Initially, the system was implemented as a pilot, and after 90 days, it came into definitive operation. From November 2012 to October 2014, the system registered 4271 patients, 480 professionals, 1483 schedules appointments, 5938 request for hospitalizations and 3239 hospitalizations. Most origin municipalities of the requests was part of the Regional Health Department XIII (RHD XIII), confirming the adequacy of regionalization. It was found that the high proportion of requests from the mental health specialized services, showed the difficulty of stabilizing patients with mental disorders by these units, showing the lack of organization and coordination with other network services. The network overloading can be justified by the high waiting time for hospitalization, and the bed turnover decrease, damaging the network patients flow. It was shown that the majority of the population treated in hospital admissions was male, between 20 to 39 years, diagnosed with disorders related to the use of psychoactive(s) substance(s) use and length of stay more than or equal to 31 days. The longer length of stay by the compulsory admissions compared with voluntary and involuntary admissions, causes reduction in the bed turnover, reflecting on the entire mental health network. The high proportion of counter references to mental health specialist services can contribute to the continuity of care, however, it was found that only 54,92 % of the discharges were counter referenced. The low level use of the appointments features along with the low number of user actions by requesters, suggests the improvement and / or inclusion of features in the system for outpatient services. The increase of 13,16% in the total number of actions from one year to another can be explained by the incorporation of the system in the daily working process, since users of the system were seen and recognized as an integral part in the system development, allowing their engagement in its use and improvement.
