DEFINITION AND SOURCE INFORMATION
Unit of Measurement
Ratio
Calculation Methods
Clients with <2 interRAIHC assessments within 365d
Numerator including inclusion/exclusion
Change in MDSHSI score from first to most interRAIHC assessment
Denominator including inclusion/exclusion
Total population age 66 years or older with an interRAIHC assessment in the observation period (index assessment) and a second interRAIHC assessment within 365d prior. The index assessment is the most recent in the
observation period.
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
interRAIHC data was not available in 2017/18 • 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. Therefore, a higher value (mean change score) is desirable for this indicator • 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.
