78.1: VITAL STATISTICS INFORMATION
• What are the key causes of illness or death in Canada?– Common things are common
• using epidemiology can help you run a better clinical practice
• How have disease incidence and mortality changed in Canada in the past 20 years?– Little good information on disease incidence except for
reportable diseases and cancer (cancer registries)
