Healthy Hospital HS.REGISTER Audit-Trail



At IPOPorto (an oncology hospital) HLTSYS has performed server and network audits, and also implement a HL7 message integration auditing system. HLTSYS also installed and still maintains an integration engine to manage the communications among the existing Information Systems.

Oporto, June 18th, 2015 – the HELIOS, a software solution developed to support clinical management and integration, won the IDC CIO Awards last June 17th. The software is already in use at IPO Porto, and it allows real time monitoring of information production and data exchange across departments.

HLTSYS is performing consultancy to the ANF (the Portuguese National Pharmacy Association) regarding
Patient Data Anonymization. We have performed iteratively the tasks of:

  • Anonymization protocol design ;
  • Validation and implementation of Risk Analysis ;
  • Production of requests, opinions and reports to law enforcement

HLTSYS provides the maintenance and monitoring services to the Hospital Information Systems developed and installed by the Faculty of Medicine of the University of Porto (FMUP). These systems are currently installed in 8  Portuguese hospitals, and FMUP personal is able to monitor them all. HLTSYS has developed a remote monitoring system with sensors for hardware, operating systems, integration responsiveness, information flow and quality of data.



Our solution aims to create a single audit trail for health institutions that collects different logs (ex: syslog, log4j, HL7, web servers logs). This solution is aligned with the IHE-ATNA (Audit Trail and Node Authentication) profile. It allows to perform audit processes that cross different systems in an integrated manner, as well as to diagnose problem occuring in different systems using a single dashboard.
