BC Children's Hospital Research Institute is pleased to congratulate the recipients of the 2018 Outstanding Achievement Awards and the 2018 BCCHR Studentships and Fellowships.
I grew up and took my basic medical training in what used to be called Rhodesia (now Zimbabwe). After graduating, I worked as a district health doctor in remote rural hospitals. My continuing interest in the health of people living in poverty dates to that time. After moving to Canada with my family, I worked as a resident at BC Children's Hospital before taking further sub-specialty training in pediatric respiratory diseases plus a second fellowship in pediatric intensive care. After completing this training I joined the BC Children's Hospital
staff, splitting my time between the intensive care unit and the respiratory division. More recently, I have left the ICU and I am currently the head of the division of respiratory medicine.
My research interests reflect my past clinical experience. My primary interest has always been international health. I have published two books on the subject and also teach a credit course on international health at UBC. I currently run a large multi-centre trial in India looking into childhood pneumonia. I also like investigating topical questions in clinical respiratory medicine, including the very specialised respiratory topic of children that need mechanical ventilation in their homes.

Quality of life for children who need home ventilation and their caregivers. Medical advances over the last 20 years have produced a revolution in child survival. Many of these survivors lead normal lives but a few require some form of assisted ventilation. The trend is to manage these patients in their homes. Numbers have risen steadily to the point that there are now 150 patients registered in the home ventilation clinic from places all over BC. This is now the largest home ventilation clinic in Canada. We are just starting a questionnaire-based study of the quality of life of the affected children and their caregivers. We will also be monitoring extra health-related expenses the family must meet. This is the first study of this kind ever undertaken in children. The results will be a valuable addition to home care planning.
The use of hi-flow nasal oxygen in the treatment of viral bronchiolitis. Bronchiolitis is the single most common cause for admission to pediatric hospitals, including our own. The disease has enormous economic and health consequences. Survivors are frequently left with significant long term health problems including asthma. Despite considerable research, there are no effective therapies other than symptom support. Over this last winter, we conducted a prospective controlled study of the use of hi-flow nasal oxygen in children with bronchiolitis. It was a low-incidence winter so we only managed to enroll 50 patients. Fortunately, we registered our study and it was noticed by staff at Children's Hospital in Sydney, Australia. They now have research clearance to run the same protocol during their bronchiolitis season which starts in June. Hopefully this will allow us to get over 100 patients which will allow us to analyse the data. If numbers are low then we will run the study again in our next winter. This has the potential to improve the care of this common condition so we hope to finish the analysis and submit the work as soon as possible.
Improving the diagnosis of respiratory diseases in children living in low-resource conditions. Each year, over a million children die from lung infections. Accurate diagnosis is a fundamental requirement for the improved treatment protocols needed to reduce this terrible annual mortality. During the last winter we organised a large study involving 5 Indian hospitals. The aim was to define accurate diagnostic criteria to improve the prediction of the major respiratory illnesses affecting children. The organisation worked well. We stopped the study at the end of the viral season in May. At that stage, we had enrolled over 700 patients. The data analysis is not yet complete but clear diagnostic criteria have emerged that will be valuable in advancing the fight against pediatric respiratory deaths.Grants
