Overview

Clinical Epidemiology is a “basic science for clinical medicine”, it is the scientific process of learning from groups of patients to develop better ways to prevent, diagnose, treat and monitor diseases. Dr. Guzman applies clinical epidemiology methods to childhood rheumatic diseases in collaboration with other researchers and clinicians. He advises on the design, planning, analysis and interpretation of clinical studies.

Dr. Guzman is a physician who cares regularly for children with rheumatic diseases, the same children he hopes to help with his research. Three of his current projects investigate: 1) what are the top priorities of children with arthritis and their parents in dealing with arthritis, and how to foretell what a given child can expect from the disease; 2) how physical activity impacts arthritis in children; and 3) whether mobile technologies can help document the impact of arthritis and its treatment on the day-to-day lives of children.

Research

Measuring What Counts: Documenting the Impact of Arthritis on Children's Daily Community Activities.
Children with Juvenile Idiopathic Arthritis (JIA) are less active and less involved in community activities than their healthy peers. Children and families who attend the arthritis clinic say what "counts" for them is how much JIA interferes with the child's ability to participate in family, peer and community activities. Currently, this is assessed by informal conversations or standard questionnaires; but these reflect poorly on changes induced by disease of treatment. Our goal is to develop a better method to measure how JIA treatments impact the child's physical activity and community participation. In this study children with JIA wear an accelerometer and a smartphone attached to an elastic belt for one week before and one week after a treatment. The phone and accelerometer use special software to document how treatment impacted mobility and their ability to participate in activities at home and school.

CIHR Team in Linking Exercise, Physical Activity and Pathophysiology in Childhood Arthritis: A Canadian Collaborative Team (LEAP).
Identifying, characterizing and understanding the relationship of physical activity with arthritis signs and symptoms and the development of bone and muscle in children with Juvenile Idiopathic Arthritis (JIA) will provide the evidence required to rationally incorporate Physical Activity into the care of children with JIA. This cross-Canada study funded by the Canadian Institutes of Health Research will define what determines the level of physical activity in children with arthritis, and how the level of physical activity impacts the symptoms and signs of the disease, blood markers of inflammation and the development of joints, bones and muscle.

What matters the most for parents, patients and clinicians in predicting the course of Juvenile Idiopathic Arthritis?
Some children with juvenile idiopathic arthritis (JIA) have a mild disease course that requires little treatment, and others have a severe disease course that requires aggressive treatment despite its attendant toxic effects. However, our ability to predict who will have a severe disease course is limited, and parents and patients have not been systematically consulted about their priorities in defining the course and outcomes of JIA. With funding from the Canadian Initiative for Outcomes in Rheumatology Care (CIORA) we are conducting focus groups and reciprocal interviews (participants interview each other) to gather the opinions of parents, patients and clinicians about the clinical features that should be used to define the course and outcomes of JIA, the terms that should be used to describe JIA disease course, and the desirable attributes of a tool to predict the course of JIA.
