Early Career Researchers

I am a senior research fellow within the NHMRC funded Wiser Healthcare Collaboration, with appointments at the University of Sydney and Bond University. I am a medically trained epidemiologist with expertise in the evaluation of tests used for screening, diagnosis and monitoring, including cancer screening and surveillance. I am leading a number of collaborative research projects relating to overdiagnosis (both primary studies and new analysis of existing datasets). I am also leading several primary studies conducted in patients with melanoma, including a pilot randomised controlled trial of surveillance methods; an observational study (questionnaire and phone interview), and a qualitative study. Other studies I am leading include methodological studies related to estimating cardiovascular risk, long term effects of interventions to prevent cardiovascular disease, and the population impact of interventions.

Carissa’s research focusses on cardiovascular disease, primary care, behavioural science, implementation and e-health. Her NHMRC/Heart Foundation fellowship involves developing new online systems to implement general practice guidelines. This will involve linking guidelines to updated evidence summaries, audit and feedback activities and patient decision aids, with a focus on cardiovascular disease prevention. Her work uses mixed methods including:

  • Qualitative (interview, think aloud, content analysis)
  • Quantitative (systematic review, survey, experiment, pre-post piloting, RCT)

Doctors and patients can too easily fall into decision making traps that result in some people missing out on useful medications, while other people end up taking medications that they don’t need. Carissa is a behavioural scientist and her research aims to find the best ways to communicate information about health risks, so that doctors and patients can make informed decisions. Specifically, her interests include risk perception, doctor-patient communication and medical decision making, and you can find me discussing these issues on twitter (@carissa_bon).

Using a practical definition of “low value care” as care that a clinician group (such as Choosing Wisely or EVOLVE initiatives) has recommended not be used, I am developing direct measures of the use of low value care in NSW public hospitals. I create indicators based on diagnosis and procedure codes and other relevant variables in the hospital admissions data to capture use of services in patient groups where the service provides no benefit.

I completed my Master of Biostatistics through the NSW Health Biostatistical Officer Training Program in July 2011. As part of the Training Program, I completed placements in the Centre for Aboriginal Health at the Ministry of Health, the Perinatal Research Group at the Kolling Institute of Medical Research, and the Bureau of Health Information. I then worked as a contract biostatistician in the Centre for Epidemiology and Evidence at the Ministry. In April 2012 I joined the Cancer Epidemiology and Services Research Group (CESR) and the Surgical Outcomes Research Centre (SOuRCe) in the Sydney School of Public Health as a Research Officer (Biostatistics). In March 2015 I began my PhD in low value care.

After undertaking honours in Psychology at the University of Sydney, Tessa started her PhD in July 2016 in the School of Public Health, under the leadership of Dr Jesse Jansen, Professor Kirsten McCaffery, Dr Jolyn Hersch and Professor Jenny Doust. Tessa is investigating the areas and pathways of overdiagnosis of Polycystic Ovary Syndrome (PCOS) and the impact of the PCOS disease label on psychosocial outcomes and decision making.

Tessa’s research consists of a four-part mixed-methods study focusing on the impact of the PCOS label, and investigating the areas and pathways leading to overdiagnosis. PCOS disease definitions have expanded without clear evidence of benefits for the women being diagnosed, and have contributed to an increase in prevalence from traditional estimates of 4-6.6% to now affecting up to 21% of reproductive aged women.

The first two stages will consist of qualitative investigations regarding (1) the views and experiences of clinicians who diagnose and manage PCOS, and (2) the impact of the diagnosis on psychosocial wellbeing and lifestyle from the patient perspective, for women with both mild and more severe manifestations of symptoms associated with PCOS.
