There will be new limitations to the data contained in 2022 OHT-specific reports. The limitations are a result of the lag in updating the attribution methodology used to derive the population numbers for OHTs. New births in the province and patients moving into, out of, and around the province are not captured in these analyses.

Specifically, please be aware of the following caveats, and note that these caveats do NOT apply to the 2022 data report for “All Ontario”:

1.The N for under 5 years of age is low in the OHT-specific reports as children born in or moving to the region after the last attribution date are not captured in the data. We estimate a 30-40% discrepancy between the actual numbers and the numbers we were able to capture in the OHT-specific analyses.

2. All OHTs have seen their total attributed numbers fall due to the removal of people who have died, or no longer have OHIP numbers/no longer meet inclusion criteria (e.g., maximum age, years since last OHIP billing).

Due to these limitations, percentages should be used for data interpretation

Again, this limitation does not apply to all Ontario numbers as all Ontarians are included, even those not attributed to a specific OHT.
