  1. aResident Assessment Instrument for Home Care (RAI-HC). The Cognitive Performance Scale (CPS) uses items on memory and communication skills to create a 7-point scale from 0 (intact) to 6 (very seve re) [35]. The Instrumental Activities of Daily Living (IADL) scale [36] provides a measure of the customer’s self-performance of seven daily tasks: meal preparation, ordinary housework, managing finances, managing medications, phone use, shopping and transportation. The scores are from 0 to 21. The Method for Assigning Priority Levels (MAPLe) differentiates customers into five different groups ranging from low to very high risk of health decline [34]. Higher risk group indicates a higher risk to be admitted to a long-term care facility
