The Resident Assessment Instrument-Minimum Data Set (RAI-MDS) 2.0 is a comprehensive assessment that is used to identify the preference, needs and strengths of residents of long-term care homes and patients in continuing care hospitals; it also provides a snapshot of the services they receive.

The RAI data holding includes both the Home Care Reporting System (HCRS) and the Continuing Care Reporting System (CCRS).

The Home Care Reporting System (HCRS) was launched in 2006/2007. It is a database that captures longitudinal, demographic, administrative, clinical, functional and utilization information on clients who receive publicly funded home care services. The HCRS contains data on clients at multiple points throughout clients’ home care services. Information on organization characteristics that supports comparative reporting and benchmarking is also captured.

The Continuing Care Reporting System (CCRS) was launched in 2003-04. It is a database that captures longitudinal, demographic, clinical and functional information on residents who receive continuing care services in hospital-based facilities and long-term care homes that have 24-hour nursing available. Continuing care includes long-term care (e.g., nursing or personal care homes) and hospital-based continuing care for people who require on-site delivery of supervised care 24 hours a day, 7 days a week. Long-term care is governed by provincial and territorial legislation. The admission criteria for long-term care and the services provided vary across the country.

Fields available

Both Core and Non-Core fields are available for this data set.

Core vs. Non-Core Data

Core Data: Some data available through PopData and HDPBC are ‘Core Data’. Core Data are data identified by the data provider as 'Safe Data' and eligible for pre-approved release, with the exception of PharmaNet data. Core Data includes commonly-requested data columns, but not necessarily all of the columns available in a data set. For example, some Core Data fields, such as geography or organisational codes, have been suppressed for increased privacy.

Please note that the overall data access request is subject to meeting ALL of the Five SAFEs requirements, not just the Safe Data component. For more detail on the Five SAFEs, visit the Eligibility and the FIVE Safe's model page of our website.

Non-Core Data: Non-Core Data are data NOT identified by the data provider as 'Safe Data' and thus are NOT eligible for pre-approved release. Access to Non-Core Data follows the usual processes and will not follow expedited review procedures.

For the majority of DARs, requesting access to Core Data may make the data access approval process quicker and reduce the wait time for data access. It may also reduce the need for time-consuming data amendments related to a request for additional data fields or changes to study populations.

Data update schedule

For BC, our two RAI data sets (CCRS and HCRS) usually have a 3-month lag.

Approximate data update schedule Complete data up to:
January  September 30th
April  December 31st 
July March 31st 
October  June 30th 

Please note: Our data update schedule depends on when these data are made available to us by the data provider, so the update schedule is an estimation only.

Additional information

Please note: For CCRS and HCRS year ranges in the filenames are based on the ASSESSMENT_DATE field in the ASSESSMENT tables for both datasets.
