What is Diagnostic Informatics?
Diagnostic informatics relates to the gathering, integrating, interpreting and communication of data and information, an integral part of the diagnostic process and crucial to the quality and safety of patient care.
Diagnostic informatics involves laboratory medicine, anatomic pathology and medical imaging. Whilst diagnostic testing may account for a small (less than 5%) proportion of most hospital budgets, it is considered to have a huge influence on medical decision-making . It underpins much of our health care system, generating information that is crucial to the prevention, diagnosis, prognosis, stratification of risk and treatment of disease .
Diagnostic informatics encompasses major areas of research across the diagnostic analytical process. This ranges from the clinical choice of diagnostic request, the quality and efficiency of the analytical process, right through to the interpretation and follow-up of test results and their impact on patient care outcomes.

Clinical Excellence, Safety and Value
The diagnostic informatics research team is committed to generating quality evidence to enhance clinical excellence, patient safety and the value of care. This involves:
- An outcomes-based approach to diagnostic research
- Optimised clinical workflows, engagement, governance and accountability
- Shared decision-making and patient-centred care
- IT-enhanced decision support, data analytics and knowledge management systems

AIHI Diagnostic Informatics research on rapid diagnostic testing for respiratory viruses to be published internationally
For respiratory viruses like the flu, Dr Nasir Wabe and a research team including Associate Professor Ling Li, Dr Mary Dahm, Professor Johanna Westbrook and Professor Andrew Georgiou have found there are better patient and laboratory outcomes associated with rapid diagnostic testing in Emergency Departments compared to standard testing. The research will be published in the Medical Journal of Australia and the American Society for Microbiology’s Journal of Clinical Microbiology.
AIHI Diagnostic Informatics systematic review of the impact of Health Information Technology on test result management to be published in JAMIA
Ms Yu Jia Julie Li, Dr Mary Dahm, Professor Johanna Westbrook and Professor Andrew Georgiou from the Diagnostic Informatics stream of the Centre for Health Systems and Safety Research have conducted a systematic review of the evidence on “The impact of Health Information Technology on the management and follow-up of test results”. It has been accepted for publication in the highly regarded Journal of the American Medical Informatics Association (JAMIA), the Association’s premier peer-reviewed journal for biomedical and health informatics.

Diagnosing iron deficiency in general practice: a study on pathology tests and clinical decision making in diagnosing iron deficiency based on primary care electronic health records
The use and interpretation of pathology tests can be challenging. Pathology tests used in diagnosing iron deficiency is believed to be often incorrectly interpreted in general practice, which may have an undesirable impact on the practitioner’s decision-making process. Further, ferritin levels - which are used in diagnosing iron deficiency - shows variation by age and gender that are generally not taken into account when interpreting the results. This study has two major objectives: 1) to determine how pathology testhttps://www.mq.edu.au/research/research-centres-groups-and-facilities/healthy-people/centres/australian-institute-of-health-innovation/Research-Streams/Diagnostic-informatics/_edit#s are being utilised by general practitioners in diagnosing iron deficiency, and 2) to determine the impact of variation in age and gender on ferritin test results in diagnosing iron deficiency. The outcomes of this study will provide valuable information that could be utilised to improve diagnosis of iron deficiency.

What is the Evidence for Total Serum Calcium Alert List Thresholds?
Wilson’s area of research is within the pathology testing discipline, in the area of “high risk results”– which are those results considered life-threatening to a patient in the absence of medical intervention. Specifically, Wilson is looking at critical risk alert thresholds for total serum calcium and their association with adverse patient outcomes.
