Catching cancers early? How well do Ontario’s organized screening programs perform for First Nations and Métis persons?

Background

Communities report screening program cancers in community members before screen-eligible age, late presentation of cancers and difficulties accessing screening. Previous work by research team members used qualitative, participatory research methods to document these experiences and quantitative approaches to describe risk factors, incidence and outcomes from cancer in Métis and First Nations persons in Ontario. The current project builds on these works using resources at ICES linked to OH (CCO) datasets.

The overall objective of this research project is to evaluate the effectiveness of Ontario’s organized cancer screening programs for First Nations and Métis persons.

Separate analyses will be conducted for Métis and First Nations persons. The specific aims are:

To determine the age- and sex-adjusted incidence, mortality as well as the the age-, sex- and stage-adjusted survival for screening program cancers among First Nations and Métis persons in Ontario

To compare the probability of being diagnosed with screening program cancers by age among First Nations compared to other Ontarians, while accounting for the competing risk of death and potential confounders. (e.g. sex (where relevant), up-to-date with screening program tests, remoteness, comorbidity, having a regular primary care provider)

To determine participation (adherence and follow-up after an abnormal screening test) with screening tests for breast, cervical and colorectal cancers in First Nations and Métis persons compared to the general population. Examined factors will include age, sex (where relevant), comorbidity, remoteness and having a regular primary care provider

The research team followed the ICES-First Nations Data Access Process and the ICES-Métis Data Access Process to obtain permission to use Indian Registry System (IRS) and Métis Citizenship Registry (MCR) data for this project. This process involved receiving approvals from the Chiefs of Ontario First Nations Data Governance Committee, Métis Nation of Ontario, Grand Council Treaty #3 and Kenora Chiefs Advisory.
