Description of variables
| 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 |
