Resident Assessment Instrument (RAI)
• Resident Assessment Instruments (RAI) include 2 components: an assessment tool (MDS); and a screening protocol .
• The instruments were developed and are used in over 30 countries.
• There are 5 RAIs each based on an MDS instruments (interrai.org, 2010)
• The instruments can be combined into an integrated health assessment system (Morris et al., 1997)
• The RAI was originally constructed as a care planning tool, but has been proven to be effective for research (Stones et al., 2006)

RAI• The MDS consists hundreds (over
230) of different items that measure various constructs (Stevenson et al., 2006)
• The data is collected by trained assessors, and has been shown to have high levels or reliability (inter-rater) (Morris et al., 1997)
• RAPs (CM&MS, 2002)
• Depression Rating Scale (Burrows, et al.,
2000) • Cognitive Performance Scale (Morris et al.,
1994) • Activities of Daily Living Scale (Morris et al.,
1999) • RAI-HC Canada

RAI-HC and the Health of Minority Francophones in Ontario
Some Context
• The largest population of Francophones outside Québec resides in Ontario
• There are over 450,000 Francophones in Ontario
• 75,500 are over 65 (17% of the Francophone population)(Statistics Canada, 2008)
• Most studies are at a national level

Some Context
• SES (Picard & Charland, 1999; Bouchard et al., 2006, Wagner et al., 2002; Statistics Canada, 2001)
• Health Services Use (Kobayashi, 2003; Bouchard et al., 2006; Picard & Allaire, 2005; Picard & Hébert, 1999)
• Physical Health (Picard & Hébert, 1999; Statistics Canada, 2005; 2007; Wharry, 1997; Kopec et al., 2005; 2007; Picard & Allaire, 2005; Statistics Canada, 2007)
• Medication Usage (Hogan, 1995; McKellar, 1999; Bouchard et al., 2005)
• Mental Health (Cairney & Krause, 2005; Streiner et al., 2006; Bouchard et al., 2006)

Method of the Study (Thériault & Stones, 2009)
• RAI-HC data from the 2000 Health Informatics Project
• N = 5570• Females = 69.5%
Francophones Anglophones
N= 197 (3.5%) N= 4764 (85.5%)
Female= 152 (77.2%) Female= 3312 (69.5%)

Results• SES - Significantly more trade-offs • Health Services – MLM significant interaction between the
language at the individual and Community level • Physical Health
– No differences regarding: lifestyle, oral health, disease diagnoses
– Differences in vision and perceived health– iADL and MAPLE
• Medication usage – Significantly more medication oversight for Francophones
• Mental Health – Psychotropic Medication and DRS• Cognition (CPS)• Communication (Expression and Comprehension)
