Methodology for Interoperability between Health Information Systems, for Information Management and Decision-Making

ICTS are revolutionizing not only the way of communication and interrelation between people, but also between information systems, in such a way that they allow the exchange of information between computer systems, a method will be developed to take advantage of the functionalities of the information systems dedicated to the health area, where information related to the health area can be shared, to improve the procedures related to decision making, which are vital in emergency situations, as in the case of an emergency care where it is required to know if the patient has some type of insurance or if he/she is allergic to certain medications, this information is important if an online consultation is made with the information systems. In this sense the information systems that work in the Health System, communicates with the information system of the insurance companies, to request the data of the insurance policy, as well as the hospital systems can communicate with the service providers to request medical supplies, among other applications, thanks to the interoperability, based on the XML communication standard that in its essence is the basis of the HL7 protocol, the results of the proposed methodology allow the interaction between systems, if as a development and application guide where you can create and read these messages based on XML, which can be applicable and scalable.
