Respiratory Investigation Unit
The Respiratory Investigation Unit (RIU) at Queen's University and Kingston Health Sciences Centre (Kingston General Hospital Site), under the directorship of Dr. J. Alberto Neder, was founded by Dr. Denis O’Donnell in 1990. It is a clinical respiratory physiology research group dedicated to studying the neurophysiologic mechanisms of dyspnea (respiratory discomfort) and activity limitation in patients with a variety of cardiorespiratory diseases such as chronic obstructive pulmonary disease (COPD), interstitial lung disease, and obstructive sleep apnea (OSA). Dr. Nicolle Domnik explores the relationships between sleep, exercise and breathing in healthy persons and those with sleep disordered breathing.
We employ a variety of sophisticated and integrative physiologic measurements to assess the neural drive to breathe, respiratory mechanics, pulmonary gas-exchange and acid-base balance, cardiocirculatory responses to exertion, central and peripheral neuromuscular fatigue, and lung structure-function relationships. The long-term goal is the development of novel diagnostic and innovative treatment approaches to alleviate dyspnea, increase functional capacity and improve quality of life in these patients.
The RIU participates in sponsored clinical trials and is a site for the Canadian Cohort Lung Disease (CanCOLD) study.
Asthma Research Unit
The Asthma Research Unit (ARU) was opened as part of the KGH Asthma Program within the Division of Respirology, Department of Medicine at Queen’s University. The ARU is directed by Dr. M. Diane Lougheed, Professor of Medicine Biomedical and Molecular Sciences, and Community Health and Epidemiology and Senior Adjunct Scientist, ICES-Queen’s. The research team includes research associates, graduate students and a nurse practitioner. The team collaborates with many researchers at other centres as part of research networks and team grants.
Research areas include:
- Asthma symptom perception and lung mechanics
- Cough variant asthma
- Asthma epidemiology (practice patterns and outcomes research)
- Asthma guidelines implementation and knowledge translation (e.g. care maps, electronic care tools and indicators for electronic medical records)
- Asthma management (clinical trials and asthma education)
Interstitial Lung Disease Research
Dr. Onofre Moran has developed a detailed database of clinical and pulmonary function characteristics of over 800 patients with Interstitial Lung Disease (ILD) followed over several years. This is being used to identify prognostic trends in patients with ILD. He is interested in environmental causes of ILD and collaborates with the RIU to explore the basis of dyspnea in patients with this disease. Research is a component of the ILD training program that he directs.
Quality Improvement Research
Dr. Genevieve Digby’s research is focused on Quality Improvement (QI) in healthcare, including efficient resource utilization, patient flow, guideline adherence, and QI education. She is leading QI initiatives in the Lung Diagnostic Assessment Program that demonstrate improvement in quality, timeliness and equity of access to care for patients with lung cancer in Southeastern Ontario.
