Overall

The age-standardized hospitalization rate for asthma in Simcoe Muskoka for all ages and sexes in 2020 was 13.3 (10.5, 16.7) hospitalizations per 100,000 population, which was not significantly different from the Ontario rate of 16.6 (15.9, 17.3) hospitalizations per 100,000 population.

The asthma hospitalization rates dropped dramatically in 2020, by approximately 40% in Simcoe Muskoka and by 50% for Ontario overall. This sudden and dramatic drop can be attributed, at least in part, to changes in health care use and access during the COVID-19 pandemic. It is unclear how much the reduced transmission of other infectious diseases (like the common cold and influenza) and reduced exposures to activities and environments that exacerbate asthma may have contributed to the drop in the rate.

Prior to 2020, there was a significant downward trend in the asthma hospitalization rates in both Simcoe Muskoka and Ontario as a whole over the 15-year period from 2005 to 2019 with the steepest drop in the rates occurring between 2005 and 2007.

By Sex

In 2020, the age-standardized hospitalization rate for asthma among Simcoe Muskoka males was 9.9 (6.5, 14.4) hospitalizations per 100,000, which was significantly lower than the female rate of 21.0 (16.1, 27.1) hospitalizations per 100,000. These rates were not significantly different from the comparable Ontario rates for either males or females.

The 2020 asthma hospitalization rate dropped by more than 50% among Simcoe Muskoka males compared with a 20% drop among Simcoe Muskoka females. The reason for this difference in the change in 2020 between males and females in unclear. There was a sharp drop in the asthma hospitalization rates among Simcoe Muskoka males between 2005 and 2007. This was followed by a flattening of the trend from 2007 through to 2019. The asthma hospitalization rates among Simcoe Muskoka females declined steadily from 2005 to 2011, followed by a flattening of the trend from 2011 to 2019.
