Research interests

My primary areas of interest include geriatric assessment, mental health, health care and service delivery, case mix systems, quality measurement, health information management, and quantitative research methods. Working as the senior Canadian Fellow and as a Board Member of interRAI, an international consortium of researchers from over 35 countries, I also chair interRAI's International Network of Excellence in Mental Health and the interRAI Network of Canada.

Graduate supervision and student opportunities

I am currently accepting applications from graduate students with research interests related to:

  • Home care, nursing homes
  • Palliative care
  • Mental health

PhD Aging, Health and Well-being student, Joanna Sinn is supervised by Professor Hirdes. Watch her experience as she travels to a conference to deliver a presentation. Joanna is primarily interested in care transitions, resource allocation, and quality improvement. Her research uses data from various sources, including the standardized clinical assessments used internationally and developed by interRAI. Through this research, she is hoping to inform how heath care organizations and decision makers can better enable persons to live and thrive in the community.
