The Province of Ontario applies relative cost weights to acute inpatient activity submitted to the Canadian Institute of Health Information's (CIHI) Discharge Abstract Database (DAD) for a variety of purposes. The introduction of the International Statistical Classi¯cation of Diseases and Related Health Problems - Tenth Revision, Canada (ICD-10-CA) and the Canadian Classication of Health Interventions (CCI) in Ontario introduces changes in Case Mix Group (CMG^TM) assignment. Statistical methods are used to identify affected CMG. Relative cost weights are developed for use in Ontario to be applied to 2002/2003 DAD acute inpatient activity. The new relative cost weights are known as PAC-10 to reflect their application to ICD-10-CA and CCI activity. Recommendations regarding their application to weighted cases are provided.
