From: Evaluation of data quality of interRAI assessments in home and community care

Abbreviation Name Purpose Range Cut-off
ADLH Activities of Daily Living Hierarchy Categorizes ADL loss according to disablement process 0 (no impairment) – 6 (total dependence) ≥ 3 (Extensive assistance needed to total dependence)
ADL Long Form Activities of Daily Living – Long Form Sum of seven items assessing performance of ADLs 0 (independent in all ADLs) – 28 (completely dependent in all ADLs) n/a
CHESS Changes in Health, End-Stage Disease, Signs, and Symptoms Scale Measure of health instability, identifies individuals at risk of serious decline 0 (no at all unstable) – 5 (highly unstable) n/a
CMI Case Mix Index Cost weight value assigned to each RUG-III/HC group that reflects the relative resource use per day of an individual within that group compared to the overall average resource use per day within a specific population 0.45 (cost is 0.45 times that of overall average) – 5.75 (cost is 5.75 times that of overall average) n/a
CPS Cognitive Performance Scale Reflects cognition, based on memory impairment, level of consciousness, and executive function 0 (intact) - 6 (severe impairment) ≥ 3 (moderate to severe impairment)
DRS Depression Rating Scale Measures signs and symptoms of depression 0 (no mood symptoms) – 14 (all mood symptoms present in last 3 days) ≥ 3 (presence of symptoms of moderate to severe depression)
IADL Performance Scale Instrumental Activities of Daily Living Performance Scale Sum of three items assessing performance of IADLs 0 (independent in all IADLs) – 9 (completely dependent in all IADLs) ≥ 3 (at least some help needed with IADLs)
IADL Capacity Scale Instrumental Activities of Daily Living Capacity Scale Sum of three items assessing capacity to perform IADLs 0 (no difficulty to perform all IADLs) – 6 (great difficulty to perform all IADLs) ≥ 3 (some or great difficulty to perform IADLs)
MAPLe Method for Assigning Priority Levels Differentiates clients into levels based on risk of adverse outcomes, highly correlated with need for long-term care, caregiver distress, and client considered to be better off living in another setting 0 (self-reliant, no major problems in function, cognition, behaviours or environment) – 5 (presence of ADL impairment, cognitive impairment, wandering, behaviour problems) ≥ 3 (moderate to high risk of long-term care placement and/or caregiver distress)
Pain Scale   Uses two measures of pain (frequency and intensity) to create summary score 0 (no pain) – 3 (daily severe pain) n/a
RUG-III-HC Resource Utilization Groups –Home Care Reflects relative intensity of services and supports a client is likely to use Assigns clients to groups within categories (44 groups) n/a
