Numerator including inclusion/exclusion

MDSHSI score

Denominator including inclusion/exclusion

Total population age 66 years or older with an interRAIHC assessment in the observation period. For home care
clients with >1 assessment, we take the most recent.

Adjustment (risk, age/sex standardization)- detailed

Model-based risk-adjusted via generalized regression (assuming a normal distribution and identity link function) using individual-level data, controlling for age (continuous) and sex.

Caveats and Limitations

For calculation of the MDSHSI from RAI data, see: Wodchis WP, Hirdes JP and Feeny DH. Health-related quality of life measure based on the minimum data set. Int J Technol Assess Health Care. 2003; 19(3): 490-506 • MDSHSI ranges from -0.03 to 1, with higher scores (approaching 1) indicative of good health. • A value of ≥0.03 is a clinically meaningful difference in MDSHSI • The MDSHSI was validated on the RAIHC assessment instrument, which is no longer used in Ontario. Data items collected on the interRAIHC assessment instrument (which was adopted in Ontario in March 2018) differs, notably for assessing mobility, which results in a marginally higher MDSHSI score. Interpretation requires caution. • A higher value (mean score) is desirable for this measure
