Chronic obstructive pulmonary disease (COPD)

COPD is a type of obstructive lung disease that is characterized by long-term poor air flow in the lungs, with symptoms including shortness of breath, and cough with sputum production.  COPD is a chronic condition that tends to get worse over time.  The NWHU monitors local trends in hospitalization and mortality caused by COPD.

Hospitalization

Between 2010 and 2014 hospitalization rates for COPD were statistically higher in the NWHU area than in Ontario as a whole. NWHU rates were over twice as high as provincial rate, with an average of 263.3 cases per 100,000 per year versus 133.4 cases per 100,000 per year.

M​ales had slightly higher rates of hospitalization for COPD in comparison to females, an average of 284.2 cases per 100,000 vs 251.1 cases per 100,000 respectively, although the difference was not statistically significant. As well, those aged 75 years and older had the highest rates for COPD hospitalizations, at 2,831.3 cases per 100,000 per year.

Mortality

On average, mortality rates for COPD were slightly higher within the NWHU than the province of Ontario during 2007-2011 (26.9 cased per 100,000 people vs 19.7 cases per 100,000 people, respectively), although this difference was not statistically significant on average (except for in 2011). While Ontario experienced a gradual downward trend, the NWHU experienced a gradual, sharp increase from 2008 to 2010 with a subsequent dip in 2011.

Male mortality rates in the NWHU from COPD were 1.6 times as high as in females (34.6 deaths per 100,000 per year versus 21.2 deaths per 100,000 per year). As well, those ages 75 years and had the highest mortality rates from COPD of any age group (440.2 deaths per 100,000).
