Paediatric Economic Database Evaluation
Technology Assessment at SickKids (TASK)

Brief Biography

Wendy Ungar is a Senior Scientist in Child Health Evaluative Sciences at The Hospital for Sick Children (SickKids) in Toronto, a Professor in Health Policy, Management and Evaluation at the University of Toronto, and an Adjunct Scientist at the Institute for Clinical Evaluative Sciences. Dr. Ungar is a member of the Ontario Health Technology Advisory Committee (OHTAC) and chairs the Ontario Genetic Advisory Committee with a mandate to advise OHTAC on the clinical utility, validity, and value for money of new and existing genetic and genomic tests in Ontario. In 2010, Dr. Ungar’s book, Economic Evaluation in Child Health, was published by Oxford University Press.

Why do health care costs keep rising? How can we continue to afford it? Is all the new technology increasingly used in patient care actually making us healthier? With a focus on genomics, these are some of the questions that Dr. Ungar and her team address in her program of research investigating the application of health economic methods to the paediatric population.

Dr. Ungar also studies the relationship between policies governing access to prescription medicines and health outcomes in children. In 2007, Dr. Ungar started TASK (Technology Assessment at SickKids), a Health Technology Assessment (HTA) unit focusing on technology assessment of paediatric health interventions. Dr. Ungar and her research team created and maintain the PEDE database, a popular on-line health technology assessment tool for examining health economic evidence in children.

Research Interests

  • Defining and measuring value of emerging genetic testing technologies
  • Determining the use and cost-effectiveness of autism services across sectors
  • Paediatric economic evaluation methods research
  • Parent and child preferences and willingness to pay for costly paediatric technologies
  • Pharmaceutical policy and health outcomes in children

Research Activities

Sequencing technologies are poised to exert a profound impact on paediatric medicine, yet there is little research investigating their role, value for money, and patient and public preferences.

Current research is assessing the cost-effectiveness of sequencing in neurodevelopmental disorders such as autism and in cardiology where early identification of mutations may improve management and long-term outcomes. Additional research is aimed at exploring personal utility and public preferences for sequencing technologies. 

Evaluating the breadth of interventions used by children with autism of all ages, and assessing the cost-effectiveness of autism interventions is another area of active research as policy makers across Canada grapple with reforming autism programs to serve the needs of Canadian children and their families. Methodologic research to advance the tools and approaches available for child health technology assessment is integrated throughout the research.

The provision of medications is a major component of health care not universally covered by provincial health programs. Payment for medications can impose a significant financial burden on the families of children with acute or chronic diseases requiring medical treatment. A current avenue of research focuses on the health consequences in children of policies governing access to medications.
