Dympna O'Sullivan obtained a PhD in Computer Science in 2006 and a BSc in Computer Science in 2002, both from University College Dublin, Ireland. Following that she spent 18 months working as a post-doctoral fellow in Health Informatics at The University of Ottawa, Canada. She joined City University London as a Senior Lecturer in Health Informatics in 2012 after working as a Lecturer in Computer Science at Aston University since 2008.
Dympna's research is in the area of health informatics, clinical decision support systems and evidence-based medicine. In particular she is interested in managing the large volumes of data generated by today's digital healthcare environments and in developing intelligent software systems to bridge the gaps between clinician's information needs and the computational resources available to meet them. It involves the application of intelligent systems techniques including artificial intelligence, machine learning, information retrieval and ontological engineering. In addition, she is interested in knowledge management methodologies to address the problem of organizational knowledge-loss by using intelligence systems to capture and reuse knowledge from clinical tasks.
She is a member of the MET (Mobile Emergency Triage) Research Group which is directed from the University of Ottawa, Canada, and has active research collaborations with Aston University in the UK, the Centre for Affective Solutions for Ambient Living Awareness and University College Dublin in Ireland, Poznan University of Technology in Poland, and the University of North Carolina at Charlotte and Adventium Labs in the USA. She is a level 3 member (highest level) of the UK Council of Health Informatics Professionals, an Educational Affiliate member of the British Computer Society and a Fellow of the Higher Education Academy.
Dympna's research is in the area of health informatics, clinical decision support systems (CDSS) and evidence-based medicine.
Retrieving online biomedical literature
The online biomedical literature is vast with approximately 30,000 articles published annually. Furthermore many current repositories are characterised by poor indexing and querying methodologies. As a result clinicians often find it very difficult to easily retrieve information relevant for a particular presentation and patient, especially at the point of care where such information is likely to be most useful. I am interested in resolving some such issues by developing ontology-based information retrieval methodologies that can retrieve and emphasize presentation and patient specific aspects of clinical evidence rather than only aspects relating to the specified disease. I am also interested in developing methodologies for accurately ranking and presenting relevant aspects of clinical evidence for improved discrimination at the point of care.
Biomedical data mining
I am interested in developing applications for clinical decision support that utilize data mining techniques to support clinicians. Support is provided either by presenting exemplar patient cases for comparative purposes or by calculating a diagnostic predication given a current patient state. I have performed work in this area using medical imagery (using case-based reasoning to compute similar patient cases) and paediatric asthma (a classification system that employed machine leaning techniques) as sample domains.
Acceptance of clinical decision support systems among clinicians
Much research investigates acceptance of clinical decision support systems among clinicians where the focus is on the perceived usability of such systems. However, in spite of many CDSS being rated as highly usable, uptake of CDSSs among clinicians in practice is relatively low. My research in this areas focuses on other factors aside from usability that may impact the adoption of CDSSs. In particular I believe that an important role is played by clinicians' intrinsic motivation to such systems. Initial studies involving a cohort of medical doctors, and quantified using the Intrinsic Motivation Inventory, indicates that motivation to use computer-based support in general plays an important role and thus impacts the adoption of specific systems such as CDSS.
Automation of clinical practice guidelines
Clinical practice guidelines (CPG) primarily exist in non-digitized formats, either as long text-based documents summarizing relevant clinical evidence or as summarized 'flowcharts' outlining diagnoses, differential diagnoses and recommended interventions. As a result it is often difficult to directly link CPG to clinical practice. I am interested in integrating CPG with clinical workflow by developing methodologies for automating and implementing CPG. CPG attribute and values pairs, diagnoses and recommended interventions, are encoded as sets of rules and/or constraints which are executed in real-time on collected clinical data. This research allows for the practice of evidence-based medicine as well as provides improved methodologies for clinical data entry and clinical data accuracy.
