Canadian health care managers, clinicians and other health professionals face the increasingly difficult challenge of reducing costs while maintaining or improving quality of care and access.
In this environment, the importance of the information that decision-makers use to help manage health care facilities and regional health authorities has never been greater. That’s why we’ve taken a lead role in developing and implementing case-mix methodologies. These methodologies categorize patients into statistically and clinically homogeneous groups based on the collection of clinical and administrative data.
Understanding the different care requirements of patients and clients forms the basis for comparing health care organizations and case mix–adjusted resource use.
Health care facilities use these grouping methodologies and their accompanying resource indicators to effectively plan, monitor and manage the services they provide.

Case-mix products, such as Case Mix Group+ (CMG+) and the Comprehensive Ambulatory Classification System (CACS), are methodologies for grouping acute care episodes captured in CIHI’s databases.
Case mix also supports grouping methodologies for continuing and specialized care.
Resource Utilization Group, version III (RUG-III)—Grouping methodology applied to RAI-MDS 2.0 Canadian version assessment data submitted to CCRS. Effective 2011, the CCRS RUG-III (44-group) Case Mix Index (CMI) values will no longer be a separate product; they are available only with the complete CCRS RUG-III grouper product.
RUG Weighted Patient Day (RWPD) reports—Resource summary reports produced for complex continuing care and long-term care at the resident level.
Resource Utilization Group, version III, Home Care (RUG-III-HC)—Grouping methodology applied to RAI-HC Canadian version assessment data submitted to HCRS.
Rehabilitation Patient Groups (RPGs)—Grouping methodology applied to episodes based on the FIM® instrument data submitted to the NRS.
System for Classification of In-Patient Psychiatry (SCIPP)—Grouping methodology applied to MDS-MH assessment data submitted to OMHRS.
OHMRS SCIPP Weighted Patient Day (SWPD) Reports—Resource summary reports produced at the patient level.
Canadian MIS Database
The Canadian MIS Database (CMDB) is the national data source for financial and statistical information about hospitals and health regions. The day-to-day health service operations data is collected according to a standardized framework known as the Standards for Management Information Systems in Canadian Health Service Organizations (MIS Standards).
Continuing Care Reporting System
The Continuing Care Reporting System (CCRS) contains demographic, clinical, functional and resource utilization information on individuals receiving continuing care services in hospitals or long-term care homes in Canada. Participating organizations also provide information on facility characteristics to support comparative reporting and benchmarking.
Discharge Abstract Database
The Discharge Abstract Database (DAD) contains demographic, administrative and clinical data on inpatient hospital discharges. Facilities in all provinces and territories except Quebec are required to report to the DAD. Quebec acute inpatient records are submitted to CIHI through a different process and are included in the Hospital Morbidity Database.
Home Care Reporting System
The Home Care Reporting System (HCRS) contains demographic, clinical, functional and resource utilization information on clients served by publicly funded home care programs in Canada.
National Ambulatory Care Reporting System
The National Ambulatory Care Reporting System (NACRS) contains data for all hospital-based and community-based ambulatory care: day surgery, outpatient clinics and emergency departments. Client visit data is collected at the time of service in participating facilities.
National Rehabilitation Reporting System
The National Rehabilitation Reporting System (NRS) contains client data collected from participating adult inpatient rehabilitation facilities and programs across Canada, including specialized facilities and hospital rehabilitation units, programs and designated rehabilitation beds.
Ontario Mental Health Reporting System
The Ontario Mental Health Reporting System (OMHRS) contains data about individuals admitted to adult mental health beds in the province of Ontario. It includes information about their mental and physical health, as well as which social supports and services they use. The data is collected at admission, discharge and every three months for patients with extended stays.

Regrouping historical data is the process of assigning the most recent grouping methodology and resource indicators to historical data. The Regrouped Historical Data—CIHI Reference Document provides information about this regrouped historical data process.
