The burden of COPD in Canada: results from the Confronting COPD survey.

Chronic obstructive pulmonary disease (COPD) is a condition characterized by progressive airflow limitation, with symptoms of dyspnoea, cough, and sputum production. Aside from information on prevalence, mortality and hospital resource utilization arising from COPD in Canada, there is a lack of data on the impact of the disease on primary care healthcare resource utilization and the economic burden of the disease (i.e. direct and indirect costs). Canada is not unusual in this respect, as surprisingly few studies have attempted to quantify the impact of COPD on the healthcare system and society in other countries. In an attempt to address the need for information on the burden of COPD, an economic analysis of data from a large-scale international survey, Confronting COPD in North America and Europe, was conducted in Canada and six other countries. The results of the Canadian survey estimated the direct cost of the disease at CA dollar 1997.81 per patient, with over half of this due to inpatient hospitalizations. COPD also had an impact on the economy, with indirect costs amounting to CA dollar 1198.18, a third of the total per patient cost of COPD to society (CA dollar 3195.97). Reducing the impact of this disease will necessitate improvements to the way the disease is managed in primary care, as poor symptom control and frequent exacerbations are key drivers of hospital and other unscheduled care costs. Early diagnosis and the application of available but underused interventions (e.g. smoking cessation, inhaled drug therapies and pulmonary rehabilitation) could reduce the morbidity and costs of COPD in this country.
