Depending mostly on voluntarily sent spontaneous reports, pharmacovigilance studies are hampered by low quantity and quality of patient data. Enabling safety analysts to seamlessly access a wide range of Electronic Health Record (EHR) sources for collecting de-identified medical data sets of selected patient populations and tracing the reported incidents back to original EHRs can provide major improvements for such post market safety studies. The adoption of EHR systems and data exchange among these systems are rapidly increasing due to a number of national and cross-border initiatives. Although the main priority of these systems is improving clinical care, we demonstrate that the same systems and interfaces can be exploited for post market safety studies as well. We have developed an ontological framework where EHR sources and target clinical research systems can continue to use their own local data models, interfaces and terminology systems; while both structural and semantic interoperability are handled through rule-based reasoning on formal representations of different models and terminology systems maintained in our Semantic Resource Set. The Common Information Model at the core of this set acts as the common mediator. Our semantic interoperability framework for post market safety studies is scalable. The quantity and quality of the information provided through our framework to the safety analysts is a significant improvement compared to traditional methods. Semantically mediating all the patient data and terminology systems in formalized representations allows us to extend the capabilities of our tools easily.

An Extensible security infrastructure for the secondary use of electronic health records in clinical research
Eryılmaz, Elif; Toroslu, İsmail Hakkı; Doğaç, Asuman; Department of Computer Engineering (2013)
In order to facilitate clinical research studies re-using Electronic Health Records (EHR) has a great potential. Besides interoperability, safeguarding the security and privacy of the medical data in the context of secondary use for clinical research is one of the most important challenges in this respect. In order to ensure that the clinical information is shared among EHR systems and clinical research systems in an ethical and safe way, there needs to be standards-based and adaptable security and privacy ...
A Multi-layer model for privacy preserving policy making for disclosure of public health data
Alizadeh Mizani, Mehrdad; Baykal, Nazife; Department of Medical Informatics (2013)
Health organizations in Turkey collect ever-increasing amount of individual data are valuable source of information for public health research. However, due to privacy risks, they publish data in aggregated rather than individual forms. The lack of standardized policies regarding secondary uses of health data leads to ineffectiveness of available technical methods. As a result, access to and utilization of person-specific datasets by public health researchers become extremely cumbersome. The bias introduced...
Semantic transformation framework to enable statistical research on medical summaries
Paçacı, Anıl; Altıngövde, İsmail Sengör; Doğaç, Asuman; Department of Computer Engineering (2015)
One of the important aspects of the clinical research studies carried out in the pharmacovigilance and pharmacoepidemiology is the postmarketing drug surveillance. Utilization of the available Electronic Health Record (EHR) data is key to complement and strengthen the postmarketing safety studies. In addition, EHRs provide a huge, but still under-utilized source of information for the observational studies in clinical research. However, use of different EHR data models and vocabularies presents an important...
A novel report generation approach for medical applications : the sisds methodology and its applications
Kuru, Kaya; Arda, Kemal; Department of Medical Informatics (2010)
In medicine, reliable data are available only in a few areas and necessary information on prognostic implications is generally missing. In spite of the fact that a great amount of money has been invested to ease the process, an effective solution has yet to be found. Unfortunately, existing data collection approaches in medicine seem inadequate to provide accurate and high quality data, which is a prerequisite for building a robust and effective DDSS. In this thesis, many different medical reporting methodo...
