Dr. Richard Webster, has an MSc in Imaging Science and a Ph.D. in Biology. Prior to joining CHEO, he was a fellow at Health Canada working in the Genomic Laboratory of the Environmental Health Centre. Dr. Webster is now the Team Lead for Health Informatics and Big Data at the Clinical Research Unit. He contributes to the Clinical Research Unit Leadership Team, CHEO RI Data Warehouse committee, EPIC Research Application Leadership Team, as well as providing biostatistical oversight for many research projects. While based at CHEO, Dr. Webster is also a consultant for the Ontario Child Health Support Unit.
Dr. Webster’s research on child health often involves utilizing health administrative data like ICES and the CHEO RI’s data warehouse. His research interests are twofold, 1) making science more impactful and cost effective with improved statistical power analysis, and 2) improving sustainable healthcare where he collaborates with the Cochrane Climate-Health Working Group and the Centre for Sustainable Health Systems.
Poor adherence to sleep and physical activity guidelines among children with epilepsy
To assess physical activity and sleep rates in a cohort of children with epilepsy (CWE) and determine if there is a relationship between physical activity and sleep time.
Exploring data subsets with vtree
While vtree can be used to explore data, it can also be used to generate study-flow diagrams.
Decontaminating N95 and SN95 masks with Ultraviolet Germicidal Irradiation (UVGI) does not impair mask efficacy and safety: A Systematic Review
In conclusion, the function of N95 masks, based on aerosol penetration and airflow filtration, is maintained following a single cycle of UVGI. Decontamination using UV light in the laboratory setting suggests that this can be a successful method of removing infectious pathogens from FFRs. Future studies should use a cumulative UV-C dose of 40,000 J/m2 and focus on validating the effectiveness of UVGI decontamination in the real-world setting, and on determining the impact of UVGI on mask fit as well as the maximum number of UVGI cycles that can be safely applied to an N95 FFR.
Efficacy and Safety of Disinfectants for Decontamination of N95 and SN95 Filtering Facepiece Respirators: A Systematic Review
Aim:The objective of this review was to synthesize existing data on the effectiveness and safety of using disinfectants to decontaminate N95 FFR.
Cannabis treatment in children with epilepsy: Practices of Canadian neurologists
The majority of Canadian pediatric neurologists consider using cannabis as a treatment for epilepsy in children. With many gaps in evidence and high patient-driven demand for cannabis therapy, this survey provides immediate information from the “wisdom of the crowd,” to aid neurologists until further evidence is available.
