The amount of institutions with hospital information systems has increased. Different technologies and standards available makes possible to satisfy many information exchange needs. HL7's CDA is a marked-up document standard, which specifies the structure and the semantics of a clinical document. Digital Signature is a tool that guarantees the authorship and integrity of electronic documents. The Hospital Italiano of Buenos Aires, has developed and implemented a CDA documents repository along with the creation of its own PKI infrastructure, obtaining then a trustworthy and unique registry of the medical acts, making possible the access to documents in a format that allows full legibility, also allowing process and later inclusion of this information in other systems or applications, guaranteeing its authorship and integrity.
