Keywords: asthma, respiratory illness, chronic obstructive pulmonary disease (COPD)
Professor Kenneth Chapman the first recipient of the University Health Network's GSK-CIHR Chair in Respiratory Healthcare Delivery. This multi-year award recognizes and encourages his broad program of research designed to assess, improve and disseminate optimal strategies for managing the common respiratory illnesses, asthma and chronic obstructive pulmonary disease (COPD). Dr. Chapman is an internationally respected researcher in the field of asthma, COPD and airway diseases; his publications have appeared in the New England Journal of Medicine and Lancet. The titles of more than 400 publications have ranged from " Emergency medical services for outdoor rock music festivals" to "The effect of posture on thoracoabdominal movements during progressive hyperoxic hypercapnia in conscious man" . With more the 6,000 citations to his work, Professor Chapman is in the top 1% of cited medical researchers.

Dr. Chapman is currently Director of the Asthma and Airway Centre of the University Health Network and Director of the Canadian Registry for Alpha1 Antitrypsin Deficiency. Previously, he was the Canadian Network for Asthma Care. His academic appointments are as Professor of Medicine in the Faculty of Medicine with a cross-appointment to the School of Graduate Studies (Institute of Medical Science). He has supervised graduate students of varied backgrounds at the MSc and PhD levels.
  • Asthma management strategies
    It is now a standard of care that patients with unstable asthma are given a short course of oral steroids in hospital emergency rooms, walk-in clinics and offices to allow their safe discharge home. This strategy was first examined rigorously by Dr. Chapman and his colleagues who published their pivotal study in the New England Journal of Medicine (see below). This was followed by other studies examining the optimal strategies for managing asthma.

  • Patient education

    Optimizing asthma treatment outcomes requires studies on patient education, compliance, and control assessment. Recognizing this, Dr. Chapman founded the Canadian Network for Respiratory Care, an organization that manages respiratory educator certification programs for Canada. He remains active on its executive.

  • Chronic obstructive pulmonary disease (COPD)
    Dr. Chapman wrote Canada's first guidelines for the management of COPD and maintains a broad program of research in this area, addressing issues of diagnostic delay, epidemiology and non-invasive monitoring. He is a member of the CanCOLD consortium, a trans-Canadian program of study examining the natural history in a large population-based cohort of patients with COPD. He has addressed issues of gender bias in his work.

  • Alpha1 antitrypsin deficiency
    Dr. Chapman follows a large number of patients with alpha1 antitrypsin deficiency and is considered one of the world's experts in this comparatively rare lung disease. His work reflects both the Canadian perspective (from the Canadian registry) and his collaboration with international colleagues.
