Health service planners need a reliable method of forecasting the resources needed to respond to an anticipated rise in the burden of osteoarthritis as Canada’s population ages and obesity rates climb. A research team led by Dr. Deborah Marshall examined different methods of estimating the incidence and prevalence of osteoarthritis in the population using different data sources. The researchers found the administrative databases in Alberta provide valuable information for making these estimates and using the results to plan health services. Their findings are described in the latest edition of Arthritis Care & Research, a journal of the American College of Rheumatology and the Association of Rheumatology Health Professionals. Dr. Marshall is professor in the Faculty of Medicine, University of Calgary, and ABJHI’s advisor, Health Technology Assessment and Research. She holds the Canada Research Chair in Health Systems and Services Research, and the Arthur J.E. Child Chair in Rheumatology. Read the article in Arthritis Care & Research.
