The Canadian Institute for Health Information (CIHI) is supporting the effective deployment and use of the Health Based Allocation Model (HBAM) funding methodology of the Ontario Ministry of Health and Long-Term Care (MOHLTC) under the Health System Funding Strategy. This support includes providing monitoring tools, such as historical data regrouped to the 2019 HBAM Inpatient Group (HIG) and Ontario-specific Comprehensive Ambulatory Classification System (CACS) weighting methodologies. Provision of these regrouped historical data files will ensure that historical time-series analyses derived from these methodologies are relevant and useful. The output of these methodologies will be utilized as direct input into the HBAM methodology.

This bulletin concerns the 2019 methodologies that are applied to acute and ambulatory care data: HIGs for inpatient Discharge Abstract Database (DAD) records and Ontario-specific CACS weights for National Ambulatory Care Reporting System (NACRS) records. This bulletin will inform Ontario clients about how to access and read these record-level historical files. For more information regarding HBAM, please visit the MOHLTC’s website.
