Standardized Hospitalization Ratios (SHRs): Local Versus Province

Standardized Hospitalization Ratios (SHRs): Local Versus Province

Key Findings: 
  • Among Middlesex-London females, hospitalization rates for injuries and endocrine diseases were slightly higher than in Ontario (Fig. 4.15).
  • Rates for circulatory diseases, cancer and respiratory diseases in Middlesex-London females were somewhat lower than in the province (Fig. 4.15).
  • Among Middlesex-London males, hospitalization rates for injuries and respiratory diseases were slightly higher than in Ontario (Fig. 4.16). 
  • Rates for circulatory diseases, infectious diseases, and urinary diseases in Middlesex-London males were somewhat lower than in the province (Fig. 4.16).
Interpretive Notes

The Standardized Hospitalization Ratio (SHR) allows for a comparison of local to provincial rates while adjusting for the difference in age structure between the two geographic areas. It is the ratio of the number of hospitalizations in the population of Middlesex-London to the number of hospitalizations expected if the population had the same age and sex-specific hospitalization rates as the population of Ontario.

How this Indicator was Calculated: 
Ontario Public Health Standard: 

Population Health Assessment and Surveillance Protocol - Section 1, Subsections b-i, ii

Chronic Disease Prevention Standard - Requirement #1

Prevention of Injury and Substance Misuse Standard - Requirement #1

Jargon Explained

Standardized Hospitalization Ratio (SHR) 

Actual number of deaths in the Middlesex-London population divided by the number of deaths expected if the population had the same age and sex specific mortality rates as the population of Ontario.

Standardized mortality ratio (SMR) Interpretation

An SMR of 1 indicates that, after adjusting for the effect of differences in age and sex structure between the geographic areas, the mortality rate in Middlesex-London is the same as the rate for Ontario.
