Hospital Standardized Mortality Ratio: Consequences of Adjusting Hospital Mortality with Indirect Standardization

BACKGROUND The hospital standardized mortality ratio (HSMR) is developed to evaluate and improve hospital quality. Different methods can be used to standardize the hospital mortality ratio. Our aim was to assess the validity and applicability of directly and indirectly standardized hospital mortality ratios. METHODS Retrospective scenario analysis using routinely collected hospital data to co...

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...

Performance of in-hospital mortality prediction models for acute hospitalization: Hospital Standardized Mortality Ratio in Japan

OBJECTIVE In-hospital mortality is an important performance measure for quality improvement, although it requires proper risk adjustment. We set out to develop in-hospital mortality prediction models for acute hospitalization using a nation-wide electronic administrative record system in Japan. METHODS Administrative records of 224,207 patients (patients discharged from 82 hospitals in Japan ...

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...
