Change in MDSHSI score from first to most interRAIHC assessment
Denominator (short description i.e. not inclusions/exclusions)
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

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.
