CHC—community health centre, CI—confidence interval, FFS—fee-for-service, FHN—family health network, HSO—health service organization, OR—odds ratio.
↵* Cervical cancer screening: women 17–69 years. Breast cancer screening: women 50–69 years. Influenza immunization: 65 years or older or any age with a chronic condition putting patients at higher risk of influenza. Colorectal cancer screening: 50 years or older. Visual impairment screening: 65 years or older. Auditory impairment screening: 65 years or older.
↵† For each of the 6 maneuvers making up the prevention score, we evaluated the presence of the maneuver being performed in the previous 24 months in those for whom the maneuver was recommended: the age effect for those aged 50–64 was significantly larger in HSOs (−22%, 95% CI 15% to −30%) than FHNs (−12%, 95% CI −6% to −18%).
↵‡ For the overall prevention score, individuals younger than 50 years of age make up the reference category. For individual maneuvers, the younger age group for which the maneuver is indicated make up the reference category.
↵§ Statistically significant (P < .05) results.
↵‖ ORs (95% CI) for older individuals compared with younger individuals, adjusted for sex, rurality, and insurance status are shown.
↵¶ The estimated prevention score for the “typical” individual is shown. The typical individual is urban and has public health insurance.
