A Standardized dependency ratio

Hospital Standardized Mortality Ratio

HSMR is calculated as a ratio of the actual number of deaths to the expected number of deaths among patients in acute care hospitals. An HSMR of 100 indicates there is no difference between the hospital’s mortality rate and the overall average rate. Therefore a rate greater than 100 means the hospital’s mortality rate is higher than the overall average and a rate lower than 100 means the hospit...

Statistical analysis of the standardized mortality ratio and life expectancy.

A new theoretical relation that does not require the constant age-specific mortality ratio assumption is established between the standardized mortality ratio (SMR) and the life expectancy. A set of regression equations is developed from the theoretical relation to derive estimates of the future expectation of life from estimates of the SMR. Curves are presented showing the changes in life expec...

Value of hospital standardized mortality ratio unclear, administrators say.

administrators continue to express concern about the effects of hospital standardized mortality ratios (HSMRs) — particularly, negative press — proponents say it’s proving to be an effective quality improvement tool. Representatives of two regional health authorities that received unflattering scores in each of the first three reports on HSMRs in Canadian hospitals released by the Canadian Inst...
