Quantifying the arthritis pyramid for Ontario by using comprehensive community health data

Introduction: Arthritis is a leading cause of functional impairment and health care utilization in Canada and in the Western world. The aim of this investigation is to quantify the frequency, severity, and magnitude of arthritis in Ontario, Canada, using recognized databases supplemented with comprehensive, population-based survey data to facilitate informed, evidence-based planning. Materials and Methods: Data from Vital Statistics (2011, mortality), Canadian Institute for Health Information (2013, Discharge Abstract Database), Census (2011, demographic information), National Ambulatory Care Reporting System (2013, emergency department visits), and the Canadian Community Health Survey (2011/12) were used to construct an arthritis pyramid for residents of Ontario aged 15 years and older. Results and Discussion: Although arthritis is not a common cause of death, it is an important reason for hospitalizations and emergency room visits. Its greatest impact lies in the prevalence of individuals who are affected; approximately 1.8 million individuals in Ontario, and the resulting negative impact on functional ability, health care utilization, and health-care costs. The impact on society is immense and is expected to worsen as the population ages. Conclusion: A nationwide health care strategy to prevent and manage all forms of arthritis is crucial. In order to do this, we must first understand its prevalence and impact on society. This study provides a detailed information on the iceberg effect for arthritis and offers valid information for regional planning, provincial comparisons and an illustration for similar analyses nationally and internationally.
