At both dates, the screening-eligible population for each cancer type was assessed.<\/p>\n<p><strong>Exposures<\/strong> \u2014 Neighborhood income quintile, immigrant status, and primary care model type.<\/p>\n<p><strong>Main Outcomes and Measures<\/strong> \u2014 For each cancer screening type, the main outcome was whether the screening-eligible population was up to date on screening (a binary outcome) on March 31, 2019, and March 31, 2022. Up to date on screening was defined as having had a mammogram in the previous 2 years, a Papanicolaou test in the previous 3 years, and a fecal test in the previous 2 years or a flexible sigmoidoscopy or colonoscopy in the previous 10 years.<\/p>\n<p><strong>Results<\/strong> \u2014 The overall cohort on March 31, 2019, included 1\u202f666\u202f943 women (100%) eligible for breast screening (mean [SD] age, 59.9 [5.1] years), 3\u202f918\u202f225 women (100%) eligible for cervical screening (mean [SD] age, 45.5 [13.2] years), and 3\u202f886\u202f345 people eligible for colorectal screening (51.4% female; mean [SD] age, 61.8 [6.4] years). The proportion of people up to date on screening in Ontario decreased for breast, cervical, and colorectal cancers, with the largest decrease for breast screening (from 61.1% before the pandemic to 51.7% [difference, \u22129.4 percentage points]) and the smallest decrease for colorectal screening (from 65.9% to 62.0% [difference, \u22123.9 percentage points]). Preexisting disparities in screening for people living in low-income neighborhoods and for immigrants widened for breast screening and colorectal screening. For breast screening, compared with income quintile 5 (highest), the \u03b2 estimate for income quintile 1 (lowest) was \u22121.16 (95% CI, \u22121.56 to \u22120.77); for immigrant vs nonimmigrant, the \u03b2 estimate was \u22121.51 (95% CI, \u22121.84 to \u22121.18). For colorectal screening, compared with income quintile 5, the \u03b2 estimate for quntile 1 was \u22121.29 (95% CI, 16 \u22121.53 to \u22121.06); for immigrant vs nonimmigrant, the \u03b2 estimate was \u22121.41 (95% CI, \u22121.61 to \u22121.21). The lowest screening rates both before and after the COVID-19 pandemic were for people who had no identifiable family physician (eg, moving from 11.3% in 2019 to 9.6% in 2022 up to date for breast cancer). In addition, patients of interprofessional, team-based primary care models had significantly smaller reductions in \u03b2 estimates for breast (2.14 [95% CI, 1.79 to 2.49]), cervical (1.72 [95% CI, 1.46 to 1.98]), and colorectal (2.15 [95% CI, 1.95 to 2.36]) postpandemic screening and higher uptake of screening in general compared with patients of other primary care models.<\/p>\n<p><strong>Conclusions and Relevance<\/strong> \u2014 In this cross-sectional study in Ontario that included 2 time points, widening disparities before compared with after the COVID-19 pandemic were found for breast cancer and colorectal cancer screening based on income and immigrant status, but smaller declines in disparities were found among patients of interprofessional, team-based primary care models than among their counterparts. Policy makers should investigate the value of prioritizing and investing in improving access to team-based primary care for people who are immigrants and\/or with limited income.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Importance \u2014 Breast, cervical, and colorectal cancer\u2013screening disparities existed prior to the COVID-19 pandemic, and it is unclear whether those have changed since the pandemic.
