Asthma Hospitalizations From 1990-1995, asthma was responsible for 6.7% of all hospitalizations for children and youth less than 20 years of age. From 1990-1995, asthma was responsible for 6.7% of all hospital separations for children and youth less than 20 years of age in Canada.(11) Hospital separation rates (hereafter referred to as hospitalization rates) refer to the number of people in a given population who leave a hospital either through a completed procedure, discharge or death in a given time period. Hospitalization data for asthma likely reflect the more severe and/or poorly controlled cases of asthma. These data are obtained from the Discharge Abstract Database and the National Morbidity Database, which are maintained by the Canadian Institute for Health Information (CIHI). In the year 1995-96, there were 29,051 hospitalizations due to asthma among children and youth less than 20 years old in Canada (344 per 100,000). Of these, 17,582 or 60.5% occurred among children aged 0-4 years (890 per 100,000). Sex differences in the rates are notable. In the 0-4 year age group, the 1995-96 asthma hospitalization rate among males was almost double the female rate (1175 per 100,000 in boys vs. 592 per 100,000 in girls). Figure 3 illustrates the Canadian age-adjusted hospitalization rates due to asthma from 1971-1995 for two age groups of children and youth under 20 years old. The increasing asthma hospitalization rates, most notable in the 0-4 year age group, appear to have stabilized.

Hospitalizations due to asthma have also increased until recently in other countries, including Australia, Great Britain and the United States.(9) Figure 4 illustrates a trend similar to that observed in Canada in the rate of asthma-related hospitalizations in the United States.(10)
